                               SUMMARY TERM SHEET

  This summary term sheet highlights selected information from this Offer to
Purchase, and may not contain all of the information that is important to you.
To better understand our offer to you and for a complete description of the
terms of the offer, you should read the entire Offer to Purchase and the
accompanying Letter of Transmittal carefully. Questions or requests for
assistance may be directed to the Information Agent at its address and
telephone number listed on the last page of this Offer to Purchase.

Principal Terms

  .  Cobra Electronics Corporation, through its wholly owned subsidiary, is
     offering to buy all of the outstanding shares of common stock of
     Lowrance Electronics, Inc. The tender price for the common stock is
     $8.25 per share in cash. Tendering stockholders will not have to pay
     brokerage fees or commissions.

  .  The offer is the first step in our plan to acquire all of the
     outstanding shares of Lowrance common stock, as provided in our merger
     agreement with Lowrance. If the offer is successful, we will acquire
     each remaining share of Lowrance common stock in a later merger for
     $8.25 per share in cash. Lowrance stockholders will not have appraisal
     rights in the tender offer; however, they will have appraisal rights in
     the merger.

  .  The offer will expire at 12:00 midnight, New York City time, on Monday,
     February 12, 2001, unless we extend the offer.

  .  If we decide to extend the offer, we will issue a press release giving
     the new expiration date no later than 9:00 a.m., New York City time, on
     the first business day after the previously scheduled expiration of the
     offer.

Lowrance Board Recommendation

  .  By unanimous vote of all directors, the Lowrance board of directors has
     approved the merger agreement, the offer and the merger and determined
     that the terms of offer and the merger are fair to, and in the best
     interests of, Lowrance stockholders. The Lowrance board recommends that
     stockholders of Lowrance accept the offer and tender their shares in the
     offer.

Conditions

  We are not required to complete the offer unless:

  .  the number of shares of Lowrance common stock validly tendered and not
     withdrawn prior to the expiration of the offer equals at least 63 1/3
     percent of the outstanding shares of Lowrance common stock, and

  .  we receive the proceeds of debt financing in an amount necessary to
     consummate the transactions contemplated by the merger agreement on
     terms satisfactory to us in our sole discretion.

  Other conditions to the offer are described on pages 36 and 37.

Procedures for Tendering

  If you wish to accept the offer, this is what you must do:

  .  If you are a record holder of Lowrance shares (i.e., a stock certificate
     has been issued to you), you must complete and sign the enclosed letter
     of transmittal and send it with your stock certificate to the depositary
     for the offer or follow the procedures described in the offer for book-
     entry transfer. These

                                       ii
<PAGE>

     materials must reach the depositary before the offer expires. Detailed
     instructions are contained in the letter of transmittal and on pages 5
     through 7 of this document.

  .  If you are a record holder but your stock certificate is not available
     or you cannot deliver it to the depositary before the offer expires, you
     may be able to tender your shares using the enclosed notice of
     guaranteed delivery. Please call our information agent, Morrow & Co.,
     Inc. at (800) 607-0088 for assistance. See page 6 for further details.

  .  If you hold your shares through a broker or bank, you should contact
     your broker or bank and give instructions that your shares be tendered.

Withdrawal Rights

  .  If, after tendering your shares in the offer, you decide that you do NOT
     want to accept the offer, you can withdraw your shares by instructing
     the depositary before the offer expires. If you tendered by giving
     instructions to a broker or bank, you must instruct the broker or bank
     to arrange for the withdrawal of your shares. See pages 7 and 8 for
     further details.

No Subsequent Offering Period

  .  We have agreed not to provide a subsequent offering period during which
     Lowrance stockholders who do not tender in the offer would have another
     opportunity to tender at the same price. These stockholders will have to
     wait until the merger is completed to receive cash consideration. See
     page 24 for further details.

Stockholder Agreements

  .  We have entered into stockholder agreements with certain stockholders of
     Lowrance. Pursuant to those agreements, the stockholders have agreed to
     tender an aggregate of 2,044,279 shares of Lowrance common stock,
     constituting approximately 54.24% of the aggregate number of shares of
     Lowrance common stock issued and outstanding as of January 3, 2001.

  .  The stockholders have also agreed that they will not transfer their
     Lowrance shares prior to the expiration of the stockholder agreements
     and that they will vote their shares of Lowrance common stock in favor
     of the merger and against any competing transactions. You can find a
     more complete description of the stockholder agreements on page 31.

Redemption of Preferred Stock

  .  If the offer is successful, Lowrance has agreed in the merger agreement
     to redeem all 40,000 of its issued and outstanding shares of preferred
     stock at $9.375 per share in cash. This amount represents a redemption
     price of $1.875 for each share of common stock that the holders of
     preferred stock would receive if they converted the shares into common
     stock, after subtracting the applicable conversion price.

Recent Lowrance Trading Prices; Subsequent Trading

  .  The closing price for Lowrance common stock was:

      $3.12 on January 3, 2001, the last day on which there was a reported
      trade of Lowrance common stock before we announced the execution of
      the merger agreement with Lowrance, and

      $8.09375 on January 12, 2001, the last trading day before the
      commencement of the offer.

  Before deciding whether to tender, you should obtain a current market
quotation for the shares.

  .  If the offer is successful, we expect the Lowrance shares of common
     stock to be traded on the

                                      iii
<PAGE>

     Nasdaq National Market until the time of the merger, although we expect
     trading volume to be below its pre-offer level.

To: All holders of shares of common stock of Lowrance Electronics, Inc.:

                                  INTRODUCTION

  Blue Marlin, Inc., a Delaware corporation ("Purchaser") and a wholly owned
subsidiary of Cobra Electronics Corporation, a Delaware corporation ("Cobra"),
is offering to purchase all of the outstanding shares (the "Shares") of common
stock, $.10 par value ("Common Stock"), of Lowrance Electronics, Inc., a
Delaware corporation ("Lowrance"), at a purchase price of $8.25 per share, net
to the seller in cash, without interest thereon (the "Offer Price"), on the
terms and subject to the conditions set forth in this Offer to Purchase and in
the related Letter of Transmittal (which, as amended or supplemented from time
to time, collectively constitute the "Offer"). As used herein, "we" or "us"
refers to Cobra and Purchaser.

  You will not be required to pay brokerage fees or commissions or, except as
described in Instruction 6 of the Letter of Transmittal, stock transfer taxes
on the purchase of Shares in the Offer. However, if you do not complete and
sign the Substitute Form W-9 that is included in the Letter of Transmittal, you
may be subject to a required backup federal income tax withholding of 31% of
the gross proceeds payable to you. See Section 3. We will pay all charges and
expenses of American Stock Transfer and Trust Company, as Depositary, and
Morrow & Co., Inc., as Information Agent, incurred in connection with the
Offer. See Section 16.

  The Board of Directors of Lowrance (the "Lowrance Board") has by a unanimous
vote approved the Merger Agreement (as defined below), the Offer and the Merger
(as defined below), has determined that the terms of the Offer and the Merger
are fair to, and in the best interests of, Lowrance's stockholders, and
recommends that stockholders of Lowrance accept the Offer and tender their
Shares pursuant to the Offer.

  We are not required to purchase any Shares unless there shall have been
validly tendered and not withdrawn prior to the expiration of the Offer such
number of Shares that would constitute at least 63 1/3 percent of the Shares
that in the aggregate are outstanding determined on a fully diluted basis
(assuming the exercise of all options to purchase Shares, and the conversion or
exchange of all securities convertible or exchangeable into Shares, outstanding
at the expiration date of the Offer) (the "Minimum Condition"). We reserve the
right (subject to the applicable rules and regulations of the Securities and
Exchange Commission (the "SEC") and to the prior written consent of Lowrance),
which we presently have no intention of exercising, to waive or reduce the
Minimum Condition and to elect to purchase a smaller number of Shares. We also
are not required to purchase any Shares unless Cobra has received the proceeds
of debt financing in an amount necessary to consummate the transactions
contemplated by the Merger Agreement on terms satisfactory to Cobra in its sole
discretion (the "Financing Condition"). The Offer is also subject to certain
other terms and conditions. See Sections 1, 14, and 15 below.

  We are making the Offer under the Agreement and Plan of Merger (the "Merger
Agreement"), dated as of January 4, 2001, among Lowrance, Cobra and Purchaser.
Following the consummation of the Offer and the satisfaction or waiver of
certain conditions, Purchaser will merge with and into Lowrance (the "Merger"),
with Lowrance continuing as the surviving corporation (the "Surviving
Corporation"). In the Merger, each Share issued and outstanding immediately
prior to the Effective Time (as defined herein) (other than any Shares that are
held in the treasury of Lowrance or by any wholly owned subsidiary of Lowrance,
Shares owned by Cobra or by any wholly owned subsidiary of Cobra and Shares
held by stockholders who properly perfect appraisal rights under the Delaware
General Corporation Law (the "DGCL")) will be converted into the right to
receive $8.25 in cash, without interest, or any higher price per Share paid in
the Offer (the "Merger Consideration"). Section 11 below contains a more
detailed description of the Merger Agreement. Section 5 below describes the
principal federal income tax consequences of the sale or exchange of Shares in
the Offer and the Merger.

  American Appraisal Associates, Inc. ("American Appraisal"), has delivered to
the Lowrance Board a written opinion that, as of the date of the Merger
Agreement, the per Share consideration to be received by the

                                       1
<PAGE>

holders of Shares and the other terms and conditions of the Offer and the
Merger were fair from a financial point of view to such stockholders. A copy of
the American Appraisal opinion is included with Lowrance's
Solicitation/Recommendation Statement on Schedule 14D-9, which is being mailed
with this document, and stockholders are urged to read the opinion in its
entirety for a description of the assumptions made, matters considered and
limitations of the review undertaken by American Appraisal.

  The approval and adoption of the Merger Agreement by Lowrance requires the
affirmative vote of holders of 63 1/3 percent of the outstanding Shares. As a
result, if the Minimum Condition, the Financing Condition and the other
conditions to the Offer are satisfied and the Offer is completed, Cobra and its
subsidiaries will own a sufficient number of Shares to ensure that the Merger
Agreement will be approved by Lowrance's stockholders.

  Lowrance has informed us that, as of January 3, 2001, there were (a)
3,768,796 Shares issued and outstanding, and (b) 40,000 shares of Series A
Preferred Stock, par value $.50 per share (the "Preferred Stock"), issued and
outstanding . Upon the acceptance of Shares for payment by Purchaser pursuant
to the Offer, the shares of Preferred Stock will immediately be redeemed by
Lowrance. If Purchaser acquires at least 2,386,905 Shares in the Offer,
Purchaser would own 63 1/3 percent of such Shares and would own a sufficient
number of Shares to approve the Merger without the affirmative vote of any
stockholder.

  Stockholders of Lowrance owning a total of 2,044,279 Shares, constituting
approximately 54.24% of the total number of Shares outstanding as of January 3,
2001, have entered into stockholder agreements pursuant to which they have
agreed to tender those Shares pursuant to the Offer. See Section 11 below.
Lowrance has advised us that each of its directors and each of its executive
officers intends to tender all Shares that he owns in the Offer.

  The Offer is conditioned upon the fulfillment of the conditions described in
Section 14 below. The Offer will expire at 12:00 midnight, New York City time,
on Monday, February 12, 2001, unless we extend it.

  This Offer to Purchase and the related letter of transmittal contain
important information which you should read carefully before you make any
decision with respect to the Offer.

1. Terms of the Offer.

  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any extension or
amendment), we will purchase all Shares validly tendered and not withdrawn in
accordance with the procedures set forth in Section 3 of this Offer to Purchase
on or prior to the Expiration Date. The term "Expiration Date" means 12:00
midnight, New York City time, on Monday, February 12, 2001. We may terminate or
withdraw the Offer or extend the Offer from time to time, if at the then-
scheduled expiration date of the Offer, the conditions to the Offer shall have
not been satisfied or earlier waived. We may also extend the Offer for any
period required by applicable rules, regulations, interpretations or positions
of the SEC or its staff applicable to the Offer or on one or more occasions for
an aggregate period of not more than fifteen business days if there shall not
have been tendered a sufficient number of Shares to enable the Merger to be
effected without a meeting of Lowrance's stockholders in accordance with
Section 253 of the DGCL. If we extend the Offer under any of these
circumstances, the term "Expiration Date" will mean the time and date at which
the Offer, as so extended, will expire.

  Upon the terms and subject to the conditions of the Offer, we will purchase
all Shares validly tendered and not withdrawn prior to the expiration of the
Offer. If, at the Expiration Date, the conditions to the Offer described in
Section 14 have not been satisfied or earlier waived, then, subject to the
provisions of the Merger Agreement, we may extend the Expiration Date for an
additional period or periods of time by giving oral or written notice of the
extension to the Depositary. During any such extension, all Shares previously
tendered and not withdrawn will remain subject to the Offer and subject to your
right to withdraw Shares. See Section 4.

                                       2
<PAGE>

  Subject to the applicable regulations of the SEC and the terms of the Merger
Agreement, we also reserve the right, in our sole discretion, at any time or
from time to time, to: (a) delay purchase of or, regardless of whether we
previously purchased any Shares, payment for any Shares pending receipt of any
regulatory or governmental approvals or expiration of the applicable regulatory
or governmental waiting period specified in Section 15; (b) terminate the Offer
(whether or not any Shares have previously been purchased) prior to the
Expiration Date if any condition referred to in Section 14 has not been
satisfied or upon the occurrence of any event specified in Section 14; and (c)
except as set forth in the Merger Agreement, waive any condition or otherwise
amend the Offer in any respect, in each case, by giving oral or written notice
of the delay, termination, waiver or amendment to the Depositary and, other
than in the case of any waiver, by making a public announcement thereof. We
acknowledge (a) that Rule 14e-1(c) under the Exchange Act of 1934 (the
"Exchange Act") requires us to pay the consideration offered or return the
Shares tendered promptly after the termination or withdrawal of the Offer and
(b) that we may not delay purchase of, or payment for (except as provided in
clause (a) of the preceding sentence), any Shares upon the occurrence of any
event specified in Section 14 without extending the period of time during which
the Offer is open.

  The rights we reserve in the preceding paragraph are in addition to our
rights described in Section 14. Any extension, delay, termination or amendment
of the Offer will be followed as promptly as practicable by a public
announcement. An announcement in the case of an extension will be made no later
than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date. Without limiting the manner in which we
may choose to make any public announcement, subject to applicable law
(including Rules 14d-4(d) and 14d-6(c) under the Exchange Act, which require
that material changes be promptly disseminated to holders of Shares), we will
have no obligation to publish, advertise or otherwise communicate any such
public announcement other than by issuing a release to the Dow Jones News
Service.

  In the Merger Agreement, we have agreed that, without the prior written
consent of Lowrance, we will not (a) reduce the number of Shares subject to the
Offer, (b) reduce the Offer Price, (c) impose additional conditions to the
Offer other than those set forth in Section 14, or modify the conditions to the
Offer (other than to waive any condition to the Offer to the extent permitted
by the Merger Agreement), (d) except as provided in the Merger Agreement,
extend the Offer, (e) change the form of consideration payable in the Offer, or
(f) amend any other term of the Offer in a manner which is materially adverse
to the holders of Shares.

  If we make a material change in the terms of the Offer, or if we waive a
material condition to the Offer, we will extend the Offer and disseminate
additional tender offer materials to the extent required by Rules 14d-4(d),
14d-6(c) and 14e-1 under the Exchange Act. The minimum period during which a
tender offer must remain open following material changes in the terms of the
offer, other than a change in price or a change in percentage of securities
sought, depends upon the facts and circumstances, including the materiality of
the changes. In the SEC's view, an offer should remain open for a minimum of
five business days from the date the material change is first published, sent
or given to stockholders, and, if material changes are made with respect to
information that approaches the significance of price and the percentage of
securities sought, a minimum of 10 business days may be required to allow for
adequate dissemination and investor response. With respect to a change in
price, a minimum 10 business-day period from the date of the change is
generally required to allow for adequate dissemination to stockholders.
Accordingly, if prior to the Expiration Date, we decrease the number of Shares
being sought, or increase or decrease the consideration offered pursuant to the
Offer, and if the Offer is scheduled to expire at any time earlier than the
period ending on the 10th business day from the date that notice of the
increase or decrease is first published, sent or given to holders of Shares, we
will extend the Offer at least until the expiration of such period of 10
business days. For purposes of the Offer, a "business day" means any day other
than a Saturday, Sunday or a federal holiday and consists of the time period
from 12:01 a.m. through 12:00 midnight, New York City time.

  The Offer is conditioned upon, among other things, the satisfaction of the
Minimum Condition and the Financing Condition.

                                       3
<PAGE>

  Consummation of the Offer is also conditioned upon the other conditions set
forth in Section 14. We reserve the right (but are not obligated), in
accordance with applicable rules and regulations of the SEC and with the Merger
Agreement, to waive any or all of those conditions. If, by the Expiration Date,
any or all of those conditions have not been satisfied, we may, without the
consent of Lowrance, elect to (a) extend the Offer and, subject to applicable
withdrawal rights, retain all tendered Shares until the expiration of the
Offer, as extended, subject to the terms of the Offer and the Merger Agreement;
(b) waive all of the unsatisfied conditions (other than the Minimum Condition)
and, subject to complying with applicable rules and regulations of the SEC,
accept for payment all Shares so tendered; or (c) terminate the Offer and not
accept for payment any Shares and return all tendered Shares to tendering
stockholders. In the event that we waive any condition set forth in Section 14,
the SEC may, if the waiver is deemed to constitute a material change to the
information previously provided to the stockholders, require that the Offer
remain open for an additional period of time and/or that we disseminate
information concerning such waiver.

  There will not be a subsequent offering period after the expiration of the
Offer.

  Lowrance has provided us with its stockholder lists and security position
listings for the purpose of disseminating the Offer to holders of Shares. We
will mail this Offer to Purchase, the related Letter of Transmittal and other
relevant materials to record holders of Shares and we will furnish the
materials to brokers, dealers, commercial banks, trust companies and similar
persons whose names, or the names of whose nominees, appear on the
securityholder lists or, if applicable, who are listed as participants in a
clearing agency's security position listing, for forwarding to beneficial
owners of Shares.

2. Acceptance for Payment and Payment for Shares.

  Upon the terms and subject to the conditions of the Offer (including, if we
extend or amend the Offer, the terms and conditions of the Offer as so extended
or amended), we will purchase, by accepting for payment, and will pay for, all
Shares validly tendered and not withdrawn prior to the Expiration Date promptly
(as permitted by Section 4) after the Expiration Date. In addition, subject to
applicable rules of the SEC, we reserve the right to delay acceptance for
payment of, or payment for, Shares pending receipt of any regulatory or
governmental approvals specified in Section 15.

  For information with respect to regulatory approvals that we are required to
obtain prior to the completion of the Offer, see Section 15.

  In all cases, we will pay for Shares purchased in the Offer only after timely
receipt by the Depositary of (a) certificates representing the Shares ("Share
Certificates") or timely confirmation (a "Book-Entry Confirmation") of the
book-entry transfer of the Shares into the Depositary's account at The
Depository Trust Company (the "Book-Entry Transfer Facility") pursuant to the
procedures set forth in Section 3; (b) the appropriate Letter of Transmittal
(or a facsimile), properly completed and duly executed, with any required
signature guarantees or an Agent's Message (as defined below) in connection
with a book-entry transfer; and (c) any other documents that the Letter of
Transmittal requires.

  The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares which are the subject of the Book-Entry
Confirmation that the participant has received and agrees to be bound by the
terms of the Letter of Transmittal and that we may enforce that agreement
against the participant.

  For purposes of the Offer, we will be deemed to have accepted for payment,
and purchased, Shares validly tendered and not withdrawn if, as and when we
give oral or written notice to the Depositary of our acceptance of the Shares
for payment pursuant to the Offer. In all cases, upon the terms and subject to
the conditions of the Offer, payment for Shares purchased pursuant to the Offer
will be made by deposit of the purchase price for the

                                       4
<PAGE>

Shares with the Depositary, which will act as agent for tendering stockholders
for the purpose of receiving payment from us and transmitting payment to
validly tendering stockholders.

  Under no circumstances will we pay interest on the purchase price for Shares,
regardless of any extension of the Offer or any delay in making such payment.

  If we do not purchase any tendered Shares pursuant to the Offer for any
reason, or if you submit Share Certificates representing more Shares than you
wish to tender, we will return Share Certificates representing unpurchased or
untendered Shares, without expense to you (or, in the case of Shares delivered
by book-entry transfer into the Depositary's account at the Book-Entry Transfer
Facility pursuant to the procedures set forth in Section 3, the Shares will be
credited to an account maintained within the Book-Entry Transfer Facility), as
promptly as practicable following the expiration, termination or withdrawal of
the Offer.

  If, prior to the Expiration Date, we increase the price offered to holders of
Shares in the Offer, we will pay the increased price to all holders of Shares
that we purchase in the Offer, whether or not the Shares were tendered before
the increase in price.

  We reserve the right, subject to the provisions of the Merger Agreement, to
transfer or assign, in whole or from time to time in part, to one or more of
our wholly owned subsidiaries the right to purchase all or any portion of the
Shares tendered in the Offer, but any such transfer or assignment will not
relieve us of our obligations under the Offer or prejudice your rights to
receive payment for Shares validly tendered and accepted for payment in the
Offer.

3. Procedures for Accepting the Offer and Tendering Shares.

  Valid Tender of Shares. Except as set forth below, in order for you to tender
Shares in the Offer, the Depositary must receive the Letter of Transmittal (or
a facsimile), properly completed and signed, together with any required
signature guarantees or an Agent's Message in connection with a book-entry
delivery of Shares and any other documents that the Letter of Transmittal
requires at one of its addresses set forth on the back cover of this Offer to
Purchase on or prior to the Expiration Date and either (a) you must deliver
Share Certificates representing tendered Shares to the Depositary or you must
cause your Shares to be tendered pursuant to the procedure for book-entry
transfer set forth below and the Depositary must receive Book-Entry
Confirmation, in each case on or prior to the Expiration Date, or (b) you must
comply with the guaranteed delivery procedures set forth below.

  The method of delivery of Share Certificates, the Letter of Transmittal and
all other required documents, including delivery through the Book-Entry
Transfer Facility, is at your option and sole risk, and delivery will be
considered made only when the Depositary actually receives the Share
Certificates. If delivery is by mail, registered mail with return receipt
requested, properly insured, is recommended. In all cases, you should allow
sufficient time to ensure timely delivery.

  Book-Entry Transfer. The Depositary will make a request to establish an
account with respect to each of the Shares at the Book-Entry Transfer Facility
for purposes of the Offer within two business days after the date of this Offer
to Purchase. Any financial institution that is a participant in the system of
the Book-Entry Transfer Facility may make book-entry delivery of Shares by
causing the Book-Entry Transfer Facility to transfer the Shares into the
Depositary's account at the Book-Entry Transfer Facility in accordance with the
Book-Entry Transfer Facility's procedures. However, although Shares may be
delivered through book-entry transfer into the Depositary's account at the
Book-Entry Transfer Facility, the Depositary must receive the Letter of
Transmittal (or facsimile), properly completed and signed, with any required
signature guarantees, or an Agent's Message in connection with a book-entry
transfer, and any other required documents, at one of its addresses set forth
on the back cover of this Offer to Purchase on or before the Expiration Date,
or you must comply with the guaranteed delivery procedure set forth below.

                                       5
<PAGE>

  Delivery of documents to the Book-Entry Transfer Facility in accordance with
the Book-Entry Transfer Facility's procedures does not constitute delivery to
the Depositary.

  Signature Guarantees. A bank, broker, dealer, credit union, savings
association or other entity which is a member in good standing of the
Securities Transfer Agents Medallion Program (an "Eligible Institution") must
guarantee signatures on all Letters of Transmittal, unless the Shares tendered
are tendered (a) by a registered holder of Shares who has not completed either
the box labeled "Special Payment Instructions" or the box labeled "Special
Delivery Instructions" on the Letter of Transmittal or (b) for the account of
an Eligible Institution. See Instruction 1 of the Letter of Transmittal.

  If the Share Certificates are registered in the name of a person other than
the signer of the Letter of Transmittal, or if payment is to be made to, or
Share Certificates for unpurchased Shares are to be issued or returned to, a
person other than the registered holder, then the tendered certificates must
be endorsed or accompanied by appropriate stock powers, signed exactly as the
name or names of the registered holder or holders appear on the certificates,
with the signatures on the certificates or stock powers guaranteed by an
Eligible Institution as provided in the Letter of Transmittal. See
Instructions 1 and 5 of the Letter of Transmittal.

  If the Share Certificates are forwarded separately to the Depositary, a
properly completed and duly executed Letter of Transmittal (or facsimile) must
accompany each delivery of Share Certificates.

  Guaranteed Delivery. If you want to tender Shares in the Offer and your
Share Certificates are not immediately available or time will not permit all
required documents to reach the Depositary on or before the Expiration Date or
the procedures for book-entry transfer cannot be completed on time, your
Shares may nevertheless be tendered if you comply with all of the following
guaranteed delivery procedures:

  (a) your tender is made by or through an Eligible Institution;

  (b) the Depositary receives, as described below, a properly completed and
      signed Notice of Guaranteed Delivery, substantially in the form made
      available by us, on or before the Expiration Date; and

  (c) the Depositary receives the Share Certificates (or a Book-Entry
      Confirmation) representing all tendered Shares, in proper form for
      transfer together with a properly completed and duly executed Letter of
      Transmittal (or facsimile), with any required signature guarantees (or,
      in the case of a book-entry transfer, an Agent's Message) and any other
      documents required by the Letter of Transmittal within three trading
      days after the date of execution of the Notice of Guaranteed Delivery.
      A "trading day" is any day on which the New York Stock Exchange is open
      for business.

  You may deliver the Notice of Guaranteed Delivery by hand, mail or facsimile
transmission to the Depositary. The Notice of Guaranteed Delivery must include
a guarantee by an Eligible Institution in the form set forth in the Notice of
Guaranteed Delivery.

  Notwithstanding any other provision of the Offer, we will pay for Shares
only after timely receipt by the Depositary of Share Certificates for, or of
Book-Entry Confirmation with respect to, the Shares, a properly completed and
duly executed Letter of Transmittal (or facsimile thereof), together with any
required signature guarantees (or, in the case of a book-entry transfer, an
Agent's Message) and any other documents required by the Letter of
Transmittal. Accordingly, payment might not be made to all tendering
stockholders at the same time, and will depend upon when the Depositary
receives Share Certificates or Book-Entry Confirmation that the Shares have
been transferred into the Depositary's account at the Book-Entry Transfer
Facility.

  Backup Federal Income Tax Withholding. Under the backup federal income tax
withholding laws applicable to certain stockholders (other than certain exempt
stockholders, including, among others, all corporations and certain foreign
individuals), the Depositary may be required to withhold 31% of the amount of
any payments made to those stockholders pursuant to the Offer. To prevent
backup federal income tax withholding, you must provide the Depositary with
your correct taxpayer identification number and certify that

                                       6
<PAGE>

you are not subject to backup federal income tax withholding by completing the
Substitute Form W-9 included in the Letter of Transmittal. See Instruction 8 of
the Letter of Transmittal.

  Appointment as Proxy. By executing the Letter of Transmittal, you irrevocably
appoint our designees, and each of them, as your agents, attorneys-in-fact and
proxies, with full power of substitution, in the manner set forth in the Letter
of Transmittal, to the full extent of your rights with respect to the Shares
that you tender and that we accept for payment and with respect to any and all
other Shares and other securities or rights issued or issuable in respect of
those Shares on or after the date of this Offer to Purchase. All such powers of
attorney and proxies will be considered irrevocable and coupled with an
interest in the tendered Shares. This appointment will be effective when we
accept your Shares for payment in accordance with the terms of the Offer. Upon
such acceptance for payment, all other powers of attorney and proxies given by
you with respect to your Shares and such other securities or rights prior to
such payment will be revoked, without further action, and no subsequent powers
of attorney and proxies may be given by you (and, if given, will not be deemed
effective). Our designees will, with respect to the Shares and such other
securities and rights for which the appointment is effective, be empowered to
exercise all your voting and other rights as they in their sole discretion may
deem proper at any annual or special meeting of Lowrance's stockholders, or any
adjournment or postponement thereof, or by consent in lieu of any such meeting
or otherwise. In order for Shares to be deemed validly tendered, immediately
upon the acceptance for payment of such Shares, we or our designee must be able
to exercise full voting, consent and other rights with respect to such Shares
and other securities, including voting at any meeting of stockholders.

  Determination of Validity. All questions as to the form of documents and the
validity, eligibility (including time of receipt) and acceptance for payment of
any tender of Shares will be determined by us, in our sole discretion, which
determination will be final and binding on all parties. We reserve the absolute
right to reject any or all tenders determined by us not to be in proper form or
the acceptance of or payment for which may, in the opinion of our counsel, be
unlawful. We also reserve the absolute right to waive any of the conditions of
the Offer (subject, in the case of the Minimum Condition, to the consent of
Lowrance) or any defect or irregularity in any tender of Shares of any
particular stockholder whether or not similar defects or irregularities are
waived in the case of other stockholders.

  Our interpretation of the terms and conditions of the Offer will be final and
binding. No tender of Shares will be deemed to have been validly made until all
defects and irregularities with respect to the tender have been cured or waived
by us. None of Cobra, Purchaser or any of their affiliates or assigns, the
Depositary, the Information Agent or any other person or entity will be under
any duty to give any notification of any defects or irregularities in tenders
or incur any liability for failure to give any such notification.

  Our acceptance for payment of Shares tendered pursuant to any of the
procedures described above will constitute a binding agreement between us and
you upon the terms and subject to the conditions of the Offer.

4. Withdrawal Rights.

  Except as described in this Section 4, tenders of Shares made in the Offer
are irrevocable. You may withdraw Shares that you have previously tendered in
the Offer at any time on or before the Expiration Date and, unless theretofore
accepted for payment as provided herein, may also be withdrawn at any time
after March 17, 2001.

  If, for any reason, acceptance for payment of any Shares tendered in the
Offer is delayed, or we are unable to accept for payment or pay for Shares
tendered in the Offer, then, without prejudice to our rights set forth in this
document, the Depositary may, nevertheless, on our behalf, retain Shares that
you have tendered, and you may not withdraw your Shares except to the extent
that you are entitled to and duly exercise withdrawal rights as described in
this Section 4. Any such delay will be by an extension of the Offer to the
extent required by law.

  In order for your withdrawal to be effective, you must deliver a written or
facsimile transmission notice of withdrawal to the Depositary at one of its
addresses set forth on the back cover of this Offer to Purchase. Any

                                       7
<PAGE>

such notice of withdrawal must specify your name, the number of Shares that you
want to withdraw, and (if Share Certificates have been tendered) the name of
the registered holder of the Shares as shown on the Share Certificate, if
different from your name. If Share Certificates have been delivered or
otherwise identified to the Depositary, then prior to the physical release of
such certificates, you must submit the serial numbers shown on the particular
certificates evidencing the Shares to be withdrawn and an Eligible Institution
must guarantee the signature on the notice of withdrawal, except in the case of
Shares tendered for the account of an Eligible Institution. If Shares have been
tendered pursuant to the procedures for book-entry transfer set forth in
Section 3, the notice of withdrawal must also specify the name and number of
the account at the appropriate Book-Entry Transfer Facility to be credited with
the withdrawn Shares, in which case a notice of withdrawal will be effective if
delivered to the Depositary by any method of delivery described in the first
sentence of this paragraph. You may not rescind a withdrawal of Shares. Any
Shares that you withdraw will be considered not validly tendered for purposes
of the Offer, but you may tender your Shares again at any time before the
Expiration Date by following any of the procedures described in Section 3.

  All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by us, in our sole discretion, which
determination will be final and binding. None of Cobra, Purchaser or any of
their affiliates or assigns, the Depositary, the Information Agent or any other
person or entity will be under any duty to give any notification of any defects
or irregularities in any notice of withdrawal or incur any liability for
failure to give any such notification.

5. Material Federal Income Tax Consequences.

  Your receipt of cash for Shares in the Offer or the Merger will be a taxable
transaction for federal income tax purposes and may also be a taxable
transaction under applicable state, local, foreign and other tax laws. For
federal income tax purposes, if you sell or exchange your Shares for cash in
the Offer or the Merger, you would generally recognize gain or loss equal to
the difference between the amount of cash received and your tax basis for the
Shares that you sold or exchanged. That gain or loss will be capital gain or
loss (assuming you hold your Shares as a capital asset) and any such capital
gain or loss will be long term if, as of the date of sale or exchange, you have
held the Shares for more than one year or will be short term if, as of such
date, you have held the Shares for one year or less.

  The discussion above may not be applicable to certain types of stockholders,
including stockholders who acquired Shares through the exercise of employee
stock options or otherwise as compensation, individuals who are not citizens or
residents of the United States, foreign corporations, or entities that are
otherwise subject to special tax treatment under the Internal Revenue Code
(such as insurance companies, tax-exempt entities and regulated investment
companies).

  The federal income tax discussion set forth above is included for general
information only. You are urged to consult your tax advisor with respect to the
specific tax consequences to you of the Offer and Merger, including federal,
state, local and foreign tax consequences.

6. Price Range Of The Shares; Dividends

  According to Lowrance's Annual Report on Form 10-K for the fiscal year ended
July 31, 2000, the Shares are principally traded on the Nasdaq National Market
("Nasdaq") under the symbol "LEIX" The following table sets forth, for the
periods indicated, (a) the reported high and low sale prices for the Shares on
Nasdaq, as reported on Lowrance's Form 10-K with respect to periods occurring
in fiscal 2000 and fiscal 1999 and published financial sources, with respect to
periods occurring in the current fiscal year. During such period, Lowrance has
paid no cash dividends on the Shares.

</TABLE>

  Lowrance has not paid cash dividends for over twenty years. Lowrance's
inventory and accounts receivable line of credit agreement prohibits the
payment of dividends.

  Under the terms of the Merger Agreement, Lowrance is not permitted to declare
or pay dividends with respect to the Shares without the prior written consent
of Cobra.

  On January 3, 2001, the last day on which there was a reported trade of
Shares prior to the announcement of the execution of the Merger Agreement, the
reported closing price per Share on Nasdaq was $3.12. On January 12, 2001, the
last full day of trading prior to the commencement of the Offer, the reported
closing price per Share on Nasdaq was $8.09375.

  Stockholders are urged to obtain current market quotations for the Shares.

7. Possible Effects of the Offer on the Market for the Shares; Nasdaq
   Quotation; Exchange Act Registration; Margin Regulations.

  Possible Effects of the Offer on the Market for the Shares. The purchase of
Shares pursuant to the Offer will reduce the number of Shares that might
otherwise trade publicly and could adversely affect the liquidity and market
value of the remaining Shares held by the public. The purchase of Shares
pursuant to the Offer can also be expected to reduce the number of holders of
Shares. We cannot predict whether the reduction in the number of Shares that
might otherwise trade publicly would have an adverse or beneficial effect on
the market price for, or marketability of, the Shares or whether it would cause
future market prices to be greater or less than the Offer Price.

  Nasdaq Quotation. Depending upon the number of Shares purchased pursuant to
the Offer, the Shares may no longer meet the standards for continued inclusion
in Nasdaq, which requires that an issuer either (i) have at least 750,000
publicly held shares, held by at least 400 round lot stockholders, with a
market value of at least $5,000,000, have at least two market makers, have net
tangible assets of at least $4,000,000, and

                                       9
<PAGE>

have a minimum bid price of $1 or (ii) have at least 1,100,000 publicly held
shares, held by at least 400 round lot stockholders, with a market value of at
least $15,000,000, have a minimum bid price of $5, have at least four market
makers and have either (A) a market capitalization of at least $50,000,000 or
(b) total assets and revenues each of at least $50,000,000.

  If the Shares are no longer eligible for Nasdaq quotation, quotations might
still be available from other sources. The extent of the public market for the
Shares and the availability of such quotations would, however, depend upon the
number of holders of such Shares remaining at such time, the interest in
maintaining a market in such Shares on the part of securities firms, the
possible termination of registration of such Shares under the Exchange Act as
described below and other factors. We cannot predict whether the reduction in
the number of Shares that might otherwise trade publicly would have an adverse
or beneficial effect on the market price for or marketability of the Shares or
whether it would cause future market prices to be greater or less than the
Offer Price.

  Exchange Act Registration. The Shares are currently registered under the
Exchange Act. The purchase of the Shares pursuant to the Offer may result in
the Shares becoming eligible for deregistration under the Exchange Act.
Registration of the Shares may be terminated upon application by Lowrance to
the SEC if the Shares are not listed on a "national securities exchange" and
there are fewer than 300 record holders of Shares. Termination of registration
of the Shares under the Exchange Act would substantially reduce the
information that Lowrance would be required to furnish to its stockholders and
the SEC and would make certain provisions of the Exchange Act, such as the
short-swing profit recovery provisions of Section 16(b) and the requirements
of furnishing a proxy statement in connection with stockholders' meetings
pursuant to Section 14(a) or 14(c) and the related requirement of an annual
report, no longer applicable to Lowrance. If the Shares are no longer
registered under the Exchange Act, the requirements of Rule 13e-3 under the
Exchange Act with respect to "going private" transactions would no longer be
applicable to Lowrance. In addition, the ability of "affiliates" of Lowrance
and persons holding "restricted securities" of Lowrance to dispose of such
securities pursuant to Rule 144 promulgated under the Securities Act, may be
impaired or, with respect to certain persons, eliminated. If registration of
the Shares under the Exchange Act were terminated, the Shares would no longer
be eligible for stock exchange listing or Nasdaq reporting. We believe that
the purchase of the Shares pursuant to the Offer may result in the Shares
becoming eligible for deregistration under the Exchange Act, and it would be
our intention to cause Lowrance to make an application for termination of
registration of the Shares as soon as possible after successful completion of
the Offer if the Shares are then eligible for such termination.

  If registration of the Shares is not terminated prior to the Merger, then
the registration of the Shares under the Exchange Act and the listing of the
Shares on the Nasdaq will be terminated following the completion of the
Merger.

  Margin Regulations. The Shares are currently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System, which
have the effect, among other things, of allowing brokers to extend credit on
the collateral of the Shares for the purpose of buying, carrying or trading in
securities ("Purpose Loans"). Depending upon factors such as the number of
record holders of the Shares and the number and market value of publicly held
Shares, following the purchase of Shares pursuant to the Offer, the Shares
might no longer constitute "margin securities" for purposes of the Federal
Reserve Board's margin regulations and, therefore, could no longer be used as
collateral for Purpose Loans made by brokers. In addition, if registration of
the Shares under the Exchange Act were terminated, the Shares would no longer
constitute "margin securities."

  Projections. Lowrance does not, as a matter of course, make public forecasts
or projections as to future revenues, earnings or other income statement data.
However, certain projections (the "Projections") were provided to the Lowrance
Board of Directors, as well as to Cobra and its advisers in connection with the
negotiation of the Merger Agreement.

  The Projections were prepared by Lowrance solely for internal use and not for
publication. The Projections were not prepared with a view to complying with
the published guidelines of the SEC regarding projections or with the American
Institute of Certified Public Accountants Guide to Prospective Financial
Statements. Neither Lowrance's independent auditors, nor any other independent
accountants, have compiled, examined or performed any procedures with respect
to the prospective financial information contained in the Projections. The
Projections do not reflect any of the effects of the Offer, the Merger or other
changes that in the future may be deemed appropriate in light of the
circumstances then existing.

  The Projections necessarily are based upon numerous estimates and assumptions
that, although considered reasonable by Lowrance, are inherently subject to
significant economic, industry and competitive risks, uncertainties and
contingencies, including industry performance, general business and economic
conditions, and other matters, all of which are difficult to predict and many
of which are beyond the control of Lowrance. Accordingly, there can be no
assurance that the projected results would be realized or that actual results
would not be significantly higher, or lower, than those projected. The
inclusion of this forward-looking information should not be regarded as fact or
an indication that Cobra, Purchaser or Lowrance or anyone who received this
information considered it a reliable predictor of future results, and this
information should not be relied on as such. None of Cobra, Purchaser or
Lowrance assumes any responsibility for the validity, reasonableness, accuracy
or completeness of the forecasts. Lowrance does not intend to update or revise
the Projections.

(1) Includes a one-time income tax credit of $10.4 million for the reversal of
    Cobra's valuation allowance on its deferred tax asset.
(2) The ratio of earnings to fixed charges is computed by dividing the sum of
    earnings before the provision for income taxes and fixed charges, by total
    fixed charges. Total fixed charges consist of interest expense and the
    interest factor of all rentals, assumed to be one-third of rental expense.

  The following unaudited pro forma condensed combined financial statements are
based on the historical consolidated financial statements of Cobra and
Lowrance, combined and adjusted to give effect to the proposed acquisition of
Lowrance by Cobra (the "Acquisition").

  The following unaudited pro forma condensed combined statements of operations
for the nine months ended September 30, 2000 and the year ended December 31,
1999 give effect to the Acquisition as if it had occurred at the beginning of
the periods presented. The unaudited pro forma condensed combined statement of

                                       14
<PAGE>

operations for the nine months ended September 30, 2000 was prepared based upon
the unaudited statement of income for Cobra for the nine months ended September
30, 2000 and quarterly unaudited statements of income for the three months
ended April 30, 2000, the three months ended July 31, 2000 and the three months
ended October 31, 2000 less the unaudited statement of income for October 2000
plus the unaudited statement of income for January 2000 for Lowrance. The
unaudited pro forma condensed combined statement of operations for the year
ended December 31, 1999 was prepared based upon the statement of income of
Cobra for the year ended December 31, 1999 and quarterly unaudited statements
of income for the three months ended April 30, 1999, the three months ended
July 31, 1999, the three months ended October 31, 1999 and the three months
ended January 31, 2000 less the unaudited statement of income for January 2000
plus the unaudited statement of income for January 1999 for Lowrance.

  The following unaudited pro forma condensed balance sheet as of September 30,
2000 gives effect to the Acquisition as if it had occurred on such date and was
prepared based on the unaudited balance sheets of Cobra and Lowrance as of
September 30, 2000.

  These unaudited pro forma condensed combined financial statements should be
read in conjunction with the Cobra and Lowrance financial statements, including
notes thereto, which are included in Cobra's Annual Audited Report on Form 10-K
for the year ended December 31, 1999, Cobra's Quarterly Unaudited Report on
Form 10-Q for the nine months ended September 30, 2000, Lowrance's Annual
Audited Report on Form 10-K for the year ended July 31, 2000, and Lowrance's
Quarterly Unaudited Reports for the three months ended January 31, 2000, as
amended, the three months ended April 30, 2000 and the three months ended
October 31, 2000. See Section 8.

  The unaudited pro forma adjustments are based upon information set forth in
this Offer to Purchase and certain assumptions included in the notes to the
unaudited pro forma condensed combined financial statements. Cobra's management
believes that the pro forma assumptions are reasonable under the circumstances.
The Acquisition will be accounted for by the purchase method of accounting.
Accordingly, Cobra's total cost to acquire all of the outstanding Shares
("Purchase Consideration"), estimated to be $58.2 million including the
assumption of anticipated debt at closing of $21.9 million, transaction costs
of approximately $2.6 million, and deferred financing costs of approximately
$2.2 million, will be allocated to the assets acquired and liabilities assumed
according to their respective fair values, with the excess Purchase
Consideration being allocated to goodwill. The total cost to acquire Lowrance
is subject to change, to the extent that total debt at closing differs from
$21.9 million and to the extent that actual transaction costs differ from the
$2.6 million estimated. The final allocation of the Purchase Consideration is
dependent upon certain valuations and other studies that have not yet occurred
to make such an allocation in the accompanying unaudited pro forma condensed
combined financial statements. Accordingly, a total amount for the excess
Purchase Consideration has been included in connection with the development of
the unaudited pro forma condensed combined financial statements.

      Notes to Unaudited Pro Forma Condensed Combined Financial Statements

  The unaudited pro forma condensed combined financial statements reflects
excess Purchase Consideration over net tangible assets acquired as follows (in
thousands):

<TABLE>
      <S>                                                        <C>

       30, 2000.................................................  (11,189)
                                                                 --------
      Excess of Purchase Consideration over net tangible assets
       acquired................................................. $ 22,854 (ii)
                                                                 ========
</TABLE>
--------
(i) Estimated merger transaction costs of $2.6 million relate principally to
    investment banking fees, legal, accounting, investor relations, printing
    fees and other costs associated with the merger.

(ii) For purposes of preparing the unaudited pro forma condensed combined
     financial statements, the estimated excess of Purchase Consideration over
     net tangible assets acquired as of September 30, 2000 of $22.9 million is
     being amortized on a straight-line basis over an estimated average period
     of 15 years at a rate of $1.5 million per year. After consummation of the
     Acquisition, Cobra will utilize valuations and other studies to make a
     final allocation of the Purchase Consideration, including allocation to
     tangible assets and liabilities, identifiable intangible assets, and
     goodwill. As a result of the final allocation, the amount of the excess of
     Purchase Consideration over net tangible assets acquired and the average
     amortization period may be different from what has been assumed in
     preparation of these unaudited pro forma condensed combined financial
     statements. On an ongoing basis, Cobra will perform periodic reviews of
     goodwill and other intangible assets arising from the Acquisition to
     ensure that they are carried at recoverable amounts in light of current
     business conditions.

  Pro forma adjustments giving effect to the Acquisition in the unaudited pro
forma condensed combined statements of operations reflect the following:

  (a) Annual documentary letter of credit financing fee that is computed by
      multiplying .135% (1.625% per annum) by the average monthly documentary
      letters of credit and then summing up the applicable number of months.

  (b) Amortization of the excess of the Purchase Consideration over net
      tangible assets acquired is on a straight-line basis over 15 years.
      Refer to note (ii) above.

  (c) The total amount of funds required by Cobra is estimated to be
      approximately $58.2 million to (a) consummate the Acquisition
      (including direct transaction costs of $2.6 million and fees related to
      the financing of $2.2 million); and (b) refinance existing debt of
      Lowrance of $21.9 million estimated as of closing. The incremental
      interest expense reflects the prime rate (estimated to be 9.0% as of
      January 9, 2001) plus .875% for the revolving line of credit and long-
      term debt and 18.5% for the subordinated debt.

  (d) Includes annual agent's financing fee of $50,000 per annum.

  (e) Income tax effect of the pro forma adjustments at the applicable
      statutory federal and state income tax rates plus the elimination of
      the tax benefit recorded by Lowrance in the respective period to
      reverse its previously established deferred tax valuation allowance, as
      such tax benefit is not available to the combined entity.

  (f) Diluted net income per common share reflects the impact of Cobra's
      outstanding options on common stock. The subordinated debt includes
      payment in kind (PIK) interest of 4.5% that may be converted to 350,000
      shares of Cobra common stock at any time beginning three years after
      closing. However, the diluted net income per common share calculation
      excludes the impact of this convertible security because it is
      antidilutive. Also, Lowrance's net income per common share and weighted
      average shares outstanding have been eliminated from the pro forma
      calculations.

                                       19

  The historical financial statements of Lowrance include the following
significant non-recurring item:

    Severance costs related to closing Lowrance's Tulsa, Oklahoma
  manufacturing facility and merger costs related to Lowrance's terminated
  merger with Orbital Sciences Corporation.

  Pro forma adjustments giving effect to the Acquisition in the unaudited pro
forma condensed combined balance sheet reflect the following:

  (a) Excess of Purchase Consideration over net tangible assets acquired as a
      result of this acquisition (refer to Note (ii) above).

  (b) Estimated deferred financing costs to be amortized straight-line over
      the term of the associated financing agreements, which is five years
      for the revolving line of credit and long-term debt and eight years for
      the subordinated debt.

  (c) New borrowings to (a) finance the Purchase Consideration; (b) refinance
      existing Lowrance debt; and (c) pay for direct transaction costs and
      fees related to the new bank facility, long-term debt and subordinated
      debt. Quarterly payments of $750,000 on the long-term debt will
      commence during the first calendar year quarter after closing.

  (d) Elimination of Lowrance's stockholders' equity.

  The name, citizenship, business address, business telephone number, principal
occupation or employment and five-year business history of each of the
directors and executive officers of Cobra and Purchaser are described in
Schedule I hereto.

puts or calls, guaranties of loans, guaranties against loss or the giving or
withholding of proxies, consents or authorizations); (d) since January 16,
1999, there have been no transactions which would require reporting under the
rules and regulations of the SEC between us or any of our subsidiaries or, to
our knowledge, any of the persons listed in Schedule I to this Offer to
Purchase, on the one hand, and Lowrance or any of its executive officers,
directors or affiliates, on the other hand; and (e) since January 16, 1999,
there have been no contacts, negotiations or transactions between us or any of

affiliates, on the other hand, concerning a merger, consolidation or
acquisition, a tender offer or other acquisition of securities, an election of
directors or a sale or other transfer of a material amount of assets.

10. Background of the Offer; Contacts with Lowrance.

  On August 20, 1998, Lowrance engaged J P Morgan, a division of Chase
Securities, Inc. ("J P Morgan") as its financial advisor to assist in exploring
potential strategic alternatives, particularly a sale or merger of Lowrance. In
September 1998, representatives of J P Morgan began contacting potential
strategic and financial partners to ascertain their interest in pursuing an
acquisition of, a merger with or an investment in Lowrance. In October 1998,
Lowrance and J P Morgan requested and received from several parties, including
Orbital Sciences Corporation ("Orbital"), non-binding indication of interest
letters that stipulated the basic terms upon which these parties would be
interested in exploring a potential acquisition of, merger with or investment
in Lowrance.

                                       20
<PAGE>

  On November 23, 1998, Orbital sent a letter to J P Morgan which expressed
Orbital's interest in a potential merger with Lowrance and requested additional
time for due diligence. On December 21, 1998, Orbital informed J P Morgan of
its continued interest in a possible merger of Lowrance into Orbital in an all-
stock transaction. After consultation with Lowrance's Board, representatives of
J P Morgan informed Orbital that Lowrance was interested in the possible
merger, pending negotiation of a definitive agreement.

  After several weeks of negotiations, including discussions of the
consideration to be received by Lowrance stockholders, Orbital informed J P
Morgan on January 7, 1999 that it would be willing to increase the value of its
merger proposal to a number of shares of Orbital stock having an implied value
of $7.30 (based upon Orbital's then current per share price) for each Share.

  On March 8, 1999, the Orbital board voted unanimously to approve the stock-
for-stock merger agreement and authorized the execution of the merger
agreement, subject to negotiation of remaining issues within the ranges
authorized by the Orbital board.

  On March 11, 1999, the Lowrance Board voted unanimously to approve the stock-
for-stock merger agreement and authorized the execution of the merger
agreement, subject to negotiation of remaining issues within the ranges
authorized by the Board, and recommended that Lowrance's stockholders approve
and adopt the merger agreement.

  On the afternoon of March 11, 1999, the stock-for-stock merger agreement and
the other transaction documents were executed. Public disclosure of the
transaction was made prior to the opening of trading on Nasdaq on March 12,
1999.

  On August 18, 1999, Orbital management proposed changing the terms of the
merger agreement from a stock-for-stock merger to a cash-for-stock merger
valued at $7.30 per Share. On August 26, 1999, both the Orbital board and the
Lowrance Board voted unanimously to approve the amended merger agreement and
the Lowrance Board recommended that Lowrance stockholders approve and adopt the
amended merger agreement. On August 26, 1999, the parties executed the amended
merger agreement and other transaction documents. Public announcement of the
execution of the amended merger agreement was made on August 30, 1999.

  On September 11, 1999, Lowrance mailed a proxy statement to its stockholders
recommending that, among other things, the stockholders vote for approval and
adoption of the amended merger agreement.

  In September and subsequent to the mailing of the proxy statement, Orbital's
chief financial officer informed representatives of J P Morgan that Orbital had
been unsuccessful in its efforts to secure $150 million in privately placed
equity. Orbital's chief financial officer also informed representatives of J P
Morgan that Orbital would attempt to finance the acquisition through its
existing bank lines.

  At a special meeting of the stockholders of Lowrance held on October 12,
1999, Lowrance's stockholders approved and adopted the amended merger
agreement.

  Orbital was ultimately unsuccessful in securing the financing from its bank
group. The amended merger agreement contained a termination date of December
23, 1999, on which date Lowrance informed Orbital that the amended merger
agreement had been breached and that Lowrance was terminating the amended
merger agreement effective as of December 27, 1999.

  Following the termination of the Orbital transaction, Lowrance met with
several potential strategic and financial partners that had contacted Lowrance
on an unsolicited basis. Between February and July 2000, three potential
strategic partners and one potential financial partner contacted Lowrance on an
unsolicited basis, including Cobra.

  On July 6, 2000, James R. Bazet, President and Chief Executive Officer of
Cobra, contacted Darrell J. Lowrance, President and Chief Executive Officer of
Lowrance, to discuss the potential for a strategic business combination between
the two companies. Subsequently, Cobra's financial advisors contacted
representatives of J P Morgan to request certain information for use by Cobra
in assessing the possibility of a merger of the two companies. As a result of
these discussions, a mutual confidentiality agreement between Lowrance and
Cobra was executed.

  On July 28, 2000, Mr. Bazet, Mr. Lowrance and certain other Cobra and
Lowrance management team members met in Dallas, Texas to discuss the
possibility of a merger between the companies. Representatives of each company
presented an overview of its operations, markets, products, strategies, and
financial projections. At the conclusion of this meeting, senior management of
each company agreed that the strategic merits of a merger warranted further
discussion and it was agreed that Lowrance would provide Cobra and its advisers
with additional financial and operating information to allow Cobra to formulate
an offer to purchase all of the outstanding Shares of Lowrance.

  Between August 16 and August 29, representatives of Lowrance and Cobra had
conducted several discussions concerning the possibility of an acquisition
transaction, including price, structure, timing, due diligence and Cobra's
valuation analysis. Cobra's senior management indicated that, subject to
satisfactory completion of due diligence, Cobra would be willing to pay $8.25
per Share in cash for all of the outstanding Shares of Lowrance. Cobra
indicated that any transaction would be conditioned on Cobra obtaining adequate
financing. Cobra also indicated that it would require that Mr. Lowrance, and
possibly other stockholders of Lowrance, enter into agreements to support the
transaction.

  On August 30, during a regularly scheduled Lowrance Board meeting,
representatives of J P Morgan presented Cobra's offer to Lowrance's directors.
At this meeting, the directors were informed of all prior discussions between
senior management of Lowrance and representatives of Cobra as well as
discussions with other potential acquirers. In addition to the financial merits
of the offer by Cobra, the Board discussed the strategic rationale for the
transaction, including but not limited to, the benefits to Lowrance from access
to Cobra's Hong Kong buying office for electronic components, Cobra's ability
to use the existing capacity at Lowrance's Mexican facility, opportunities to
leverage Lowrance's existing technology in Cobra's products and opportunities
to use Cobra's mass market retail channels for distribution of Lowrance's
products.

  During the August 30 meeting, the Board also discussed the ability of the
Cobra to obtain financing to complete the transaction and concluded, based on
the presentations of representatives of J P Morgan and senior management's
views, that such financing was likely to be obtainable. Additionally, the
Lowrance Board concluded that it was extremely important that the pursuit of
the transaction not lead to any major disruptions at Lowrance, particularly
with regard to the significant new product rollouts that were well under way.

  At the conclusion of the August 30 meeting, the Board recommended that senior
management of Lowrance and representatives of J P Morgan continue to explore
the possibility of completing a transaction with Cobra at the proposed $8.25
per Share price.

  On September 11, 2000, Lowrance and Cobra executed an Exclusivity Agreement
which, among other things, provided Cobra with exclusive access to non-public
information concerning Lowrance until October 31, 2000 so that Cobra could
complete its evaluation of an acquisition of Lowrance. The agreement also
contained Lowrance's agreement not to solicit, initiate or encourage the
submission of proposals by third parties for an acquisition of Lowrance and
provided for payment of certain Cobra expenses by Lowrance in the event
Lowrance entered into a definitive agreement for an alternative transaction on
or prior to November 30, 2000.

  From mid-September through mid-October, there were a series of meetings held
between representatives of Lowrance and Cobra during which Cobra continued its
due diligence investigation of Lowrance and representatives of Cobra gathered
information about Lowrance to be used in connection with securing Cobra's
financing. Both parties agreed that Lowrance's participants in these due
diligence meetings would be limited to Mr. Lowrance, Ronald G. Weber,
Lowrance's Executive Vice President of Engineering and Manufacturing, and
Douglas J. Townsdin, Lowrance's Vice President Finance and Chief Financial
Officer, in order to preserve confidentiality and not disrupt Lowrance's
operations. These meetings were held at an off-site location in Tulsa,
Oklahoma. As part of Cobra's due diligence, representatives of Cobra met with
Lowrance's financial auditors and visited Lowrance's manufacturing facility in
Ensenada, Mexico.

  On October 11, 2000, counsel to Cobra delivered to counsel for Lowrance a
draft merger agreement and draft form of stockholder agreement to be executed
by certain stockholders of Lowrance, including Mr. Lowrance. On October 19,
2000, counsel to Lowrance transmitted comments to the draft merger agreement to
counsel for Cobra.

  On October 25, 2000, the board of directors of Cobra held a regularly
scheduled meeting at which Cobra's financial and legal advisors gave
presentations relating to the terms of the proposed merger agreement and
stockholder agreement, the status of due diligence and the status of
discussions with potential financing sources. After discussion, Cobra's board
of directors approved the Offer, the Merger and the proposed merger agreement
and stockholder agreement and authorized senior management to negotiate the
final terms of the transaction agreements and to proceed with efforts to secure
the necessary financing.

  In late October, legal advisors to Cobra and Lowrance held discussions to
negotiate the terms of the proposed merger agreement. From late October through
mid-December, Lowrance continued to supply due diligence information to Cobra
to allow Cobra to complete its due diligence investigation. During this period,
Cobra pursued discussions with various financing sources. On December 7, 2000,
at a regularly scheduled meeting, the Cobra board of directors reviewed with
Cobra's senior management the status of the transaction and Cobra's progress
towards securing financing in the form of a senior credit facility and
subordinated note financing.

  On December 22, 2000, Cobra delivered to senior management of Lowrance copies
of executed financing term sheets for a senior credit facility as well as
subordinated financing.

  Between December 26, 2000 and January 4, 2001, the legal advisors of Cobra
and Lowrance negotiated the final terms of the merger agreement and the
stockholder agreements.

  In the morning of January 4, 2001, the Lowrance Board met to consider Cobra's
offer to purchase the Shares for $8.25 per Share in cash. Lowrance Board
reviewed the terms of the Merger Agreement and received the opinion of American
Appraisal that the offer price of $8.25 per Share was fair to the stockholders
of Lowrance from a financial point of view. Thereafter, the Lowrance Board
unanimously approved the Merger Agreement, the Offer and the Merger, determined
that the terms of the Offer and the Merger are fair to, and in the best
interests of, Lowrance's stockholders and recommended that the stockholders of
Lowrance accept the Offer and tender their Shares pursuant to the Offer. In the
late afternoon of the same day, Cobra and Lowrance executed the Merger
Agreement and Mr. Lowrance, Mr. Weber, Willard P. Britton and Peter F. Foley
executed Stockholder Agreements. Public disclosure of the execution of the
Merger Agreement was made by joint press release on the morning of January 5,
2001, prior to the opening of trading of Shares on Nasdaq.

11. Purpose of the Offer and the Merger; The Merger Agreement; The
   Confidentiality Agreement; The Stockholder Agreements; Statutory
   Requirements; Appraisal Rights; Rule 13e-3; Plans for Lowrance After the
   Offer and the Merger.

  Purpose of the Offer and the Merger. The purpose of the Offer and the Merger
is for Cobra and its subsidiaries to acquire all of the outstanding Shares.
Upon the consummation of the Merger, Lowrance will become a wholly owned
subsidiary of Cobra. The acquisition of Shares has been structured as a cash
tender offer followed by a cash merger in order to effect a prompt and orderly
transfer of ownership of Lowrance from the public stockholders to Cobra and
provide stockholders with cash for all of their Shares.

   Stockholders of Lowrance who sell their Shares pursuant to the Offer will
cease to have any equity interest in Lowrance or the right to participate in
its earnings and future growth. If the Merger is consummated, non-tendering
stockholders will no longer have an equity interest in Lowrance. Similarly,
after selling their Shares pursuant to the Offer or the subsequent Merger,
stockholders of Lowrance will no longer bear the risk of any decrease in the
value of Lowrance.

  The Merger Agreement. The following summary description of the Merger
Agreement is qualified in its entirety by reference to the agreement itself,
which we have incorporated by reference in the Schedule TO that we filed with
the SEC, which you may examine and copy as set forth in Section 8 above (except
that it will not be available at the regional offices of the SEC).

                                       23

  The Offer. The Merger Agreement provides for the commencement of the Offer by
Purchaser. The obligation of Purchaser to accept for payment and pay for Shares
validly tendered pursuant to the Offer is subject to the prior satisfaction or
waiver by Purchaser of the conditions to the Offer set forth in Section 14
hereof. The Merger Agreement provides that, without the prior written consent
of Lowrance, Purchaser will not (a) reduce the number of Shares subject to the
Offer, (b) reduce the Offer Price, (c) impose additional conditions to the
Offer other than the conditions set forth in Section 14 or modify the
conditions to the Offer (other than to waive any condition of the Offer to the
extent permitted by the Merger Agreement), (d) except as described in the
following paragraph, extend the Offer, (e) change the form of consideration
payable in the Offer or (f) amend any other term of the Offer in a manner which
is materially adverse to the holders of Shares.

  We have agreed with Lowrance that we will not extend the Offer, without the
consent of Lowrance; provided, however, that without the consent of Lowrance,
we may extend the Offer (a) if, at the scheduled or extended expiration date of
the Offer any of the conditions to Purchaser's obligation to accept Shares for
payment are not satisfied or waived, until such time as such conditions are
satisfied or waived, (b) for any period required by any rule, regulation,
interpretation or position of the SEC or the staff thereof applicable to the
Offer and (c) for any reason on one or more occasions for an aggregate period
of not more than fifteen business days beyond the latest expiration date that
would otherwise be permitted under the terms of the Merger Agreement if there
shall not have been tendered a sufficient number of Shares to enable the Merger
to be effected in accordance with Section 253 of the DGCL, in each case subject
to the right of Cobra, Purchaser or Lowrance to terminate the Merger Agreement
pursuant to its terms.

  The Merger. The Merger Agreement provides that Purchaser will be merged with
and into Lowrance following the satisfaction or waiver of the conditions to the
Merger contained in the Merger Agreement. As a result of the Merger, the
separate corporate existence of Purchaser will cease and Lowrance will continue
as the Surviving Corporation.

  At the effective time of the Merger (the "Effective Time"), the Certificate
of Incorporation and Bylaws of Lowrance shall be the Certificate of
Incorporation and Bylaws of the Surviving Corporation; the directors of
Purchaser shall become the directors of the Surviving Corporation and the
officers of Lowrance shall become the officers of the Surviving Corporation.

  Lowrance has agreed in the Merger Agreement that it will, at Cobra's request,
as soon as practicable following the purchase of Shares pursuant to the Offer,
(a) prepare and file with the SEC a preliminary proxy statement relating to the
Merger Agreement and use its reasonable best efforts to respond to any comments
of the SEC and its staff and to cause the proxy statement to be mailed to its
stockholders as promptly as practicable after responding to all such comments
to the satisfaction of the staff and (b) convene a special meeting of its
stockholders for the purpose of considering the adoption of the Merger
Agreement. The Merger Agreement provides that if Purchaser or any other direct
or indirect subsidiary of Cobra owns at least 90% of the outstanding Shares,
Cobra, Purchaser and Lowrance shall take all necessary and appropriate action
to cause the Merger to become effective as soon as practicable after expiration
of the Offer without a meeting of the stockholders of Lowrance, in accordance
with Section 253 of the DGCL.

  Conversion of Securities. As of the Effective Time, by virtue of the Merger
and without any action on the part of Purchaser, Lowrance or the holders of any
securities of Purchaser or Lowrance, each Share (other than Shares held in the
treasury of Lowrance or by any wholly owned subsidiary of Lowrance, Shares
owned by Cobra or any wholly owned subsidiary of Cobra and Shares owned by
stockholders, if any, who are entitled to and who properly exercise dissenter's
rights under the DGCL) shall be converted into the right to receive from the
Surviving Corporation, in cash, without interest, the Merger Consideration.
Each share of stock of Purchaser issued and outstanding immediately prior to
the Effective Time shall, at the Effective Time, by virtue of the Merger and
without any action on the part of the holder of any shares of stock of
Purchaser, be converted into and become one fully paid and nonassessable share
of common stock of the Surviving Corporation.

                                       24

  The Merger Agreement provides that Cobra or the designated paying agent will
be entitled to deduct and withhold from the consideration otherwise payable
pursuant to the Merger Agreement to any holder of Shares such amounts as Cobra
or such paying agent is required to deduct and withhold with respect to the
making of such payment under the Internal Revenue Code or the rules and
regulations promulgated thereunder or any provision of state, local or foreign
tax law.

Proposal (as defined below), (ii) enter into any agreement with respect to or
approve or recommend any Takeover Proposal or (iii) participate in any
discussions or negotiations regarding, or furnish to any person any information
with respect to Lowrance or any of its subsidiaries in connection with, or take
any other action to cooperate in any way with respect to, or assist in or
facilitate any inquiries or the making of any proposal that constitutes, or may
reasonably be expected to lead to, any Takeover Proposal; provided, however,
that neither Lowrance nor its directors shall be prohibited from (x) complying
with Rule 14e-2 promulgated under the Exchange Act with regard to a tender or
exchange offer or (y) referring a third party to the section of the Merger
Agreement described in this paragraph or making a copy of such section
available to any third party; and provider, further, that prior to the
acceptance for payment of Shares pursuant to the Offer, if the Lowrance Board
reasonably determines that a Takeover Proposal constitutes a Superior Proposal
(as defined below), then, to the extent required by the fiduciary obligations
of the Lowrance Board, as determined in good faith by a majority thereof after
consultation with independent counsel (who may be Lowrance's regularly engaged
independent counsel), Lowrance may, in response to an unsolicited request
therefor, furnish information with respect to Lowrance and its subsidiaries to
any person pursuant to a confidentiality agreement, in customary form and in
any event containing terms, taken as a whole, at least as stringent as those
contained in the confidentiality agreement entered into between Lowrance and
Cobra, and participate in discussions or negotiations with such person. For
purposes of the Merger Agreement, "Takeover Proposal" means any proposal for
(i) a merger or other business combination involving Lowrance or any of its
subsidiaries, (ii) any proposal or offer to acquire in any manner, directly or
indirectly, an equity interest in or any voting securities of Lowrance
representing 15% or more of the Shares or of the total voting securities of
Lowrance outstanding or (iii) an offer to acquire in any manner, directly or
indirectly, a substantial portion of the assets of Lowrance or any of its
subsidiaries, other than the transactions contemplated by the Merger Agreement,
and "Superior Proposal" means a bona fide written proposal made by a third
party to acquire Lowrance pursuant to a tender or exchange offer, a merger, a
sale of all or substantially all of the assets of Lowrance or otherwise on
terms which a majority of the Lowrance Board determines in its reasonable good
faith judgment to be more favorable to Lowrance's stockholders than the Merger
(based on the advice from Lowrance's independent financial advisor that the
value of the consideration provided for in such proposal exceeds the value of
the consideration provided for in the Merger) and for which financing, to the
extent required, is then committed or which, in the reasonable good faith
judgment of a majority of the members of the Lowrance Board (based on the
advice of Lowrance's independent financial advisor), is reasonably capable of
being obtained by such third party.

  The Merger Agreement provides further that, Lowrance must advise Cobra orally
and in writing of (i) any Takeover Proposal or any inquiry with respect to or
which could lead to any Takeover Proposal received by any officer or director
of Lowrance or, to the knowledge of Lowrance, any financial advisor, attorney
or other advisor or representative of Lowrance, (ii) the material terms of such
Takeover Proposal (including a copy of any written proposal), and (iii) the
identity of the person making any such Takeover Proposal or inquiry. Lowrance
shall so advise Cobra no later than 24 hours following receipt of such Takeover
Proposal or inquiry. If Lowrance intends to furnish any person with any
information with respect to any Takeover Proposal, Lowrance is required to
advise Cobra orally and in writing of such intention not less than two business
days in advance of providing such information. Lowrance is further required to
keep Cobra fully informed of the status and material terms of any such Takeover
Proposal or inquiry.

  Third Party Standstill Agreements. During the period from the date of the
Merger Agreement through the Effective Time, Lowrance has agreed not to
terminate, amend, modify or waive any provision of any confidentiality or
standstill agreement to which Lowrance or any of its subsidiaries is a party
(other than any confidentiality or standstill agreement involving Cobra) and to
enforce, to the fullest extent permitted under applicable law, the provisions
of any such agreements, including obtaining injunctions to prevent any breaches
of such agreements and to enforce specifically the terms and provisions thereof
in any court of the United States or any state thereof having jurisdiction.

  Indemnification. Pursuant to the Merger Agreement, from and after the
Effective Time, Cobra will cause the Surviving Corporation to indemnify and
hold harmless all past and present officers and directors of Lowrance and its
subsidiaries to the same extent and in the same manner such persons are
indemnified as of the date of the Merger Agreement by Lowrance pursuant to the
DGCL, Lowrance's Certificate of Incorporation or Lowrance's Bylaws for acts or
omissions occurring at or prior to the Effective Time and shall advance
reasonable litigation expenses incurred by such officers and directors in
connection with defending any action arising out of such acts or omissions.

  Board Representation. The Merger Agreement provides that promptly after such
time as Purchaser acquires Shares pursuant to the Offer, Purchaser will be
entitled to designate at its option up to that number of directors of the
Lowrance Board, subject to compliance with Section 14(f) of the Exchange Act,
as will make the percentage of Lowrance's directors designated by Purchaser
equal to the percentage of the aggregate voting power of the Shares held by
Cobra or any of its subsidiaries; provided, however, that in the event that
Purchaser's designees are elected to the Lowrance Board, until the Effective
Time, the Lowrance Board shall have at least two directors who were directors
of Lowrance on the date of the Merger Agreement and who are not officers of
Lowrance (the "Independent Directors"). If the number of Independent Directors
shall be reduced below two for any reason whatsoever, the Independent Director
shall designate an Independent Director for purposes of the Merger Agreement
or, if no Independent Directors then remain, the other directors of Lowrance
shall designate two persons to fill such vacancies who shall not be officers or
affiliates of Lowrance or any of its subsidiaries, or officers or affiliates of
Cobra or any of its subsidiaries, and such persons shall be deemed to be
Independent Directors for purposes of the Merger Agreement. Following the
election or appointment of Purchaser's designees to the Lowrance Board and
prior to the Effective Time, any amendment, or waiver of any term or condition,
of the Merger Agreement or Lowrance's Certificate of Incorporation or Bylaws,
any termination of the Merger Agreement by Lowrance, any extension by Lowrance
of the time for the performance of any of the obligations or other acts of
Purchaser or waiver or assertion of any of Lowrance's rights under the Merger
Agreement, and any other consent or action by the Lowrance Board with respect
to the Merger Agreement, will require the concurrence of a majority of the
Independent Directors and no other action by Lowrance, including any action by
any other director of Lowrance, shall be required for purposes of the Merger
Agreement. In connection with the foregoing, Lowrance will promptly, at the
option of Cobra, either increase the size of the Lowrance Board and/or obtain
the resignation of such number of its current directors as is necessary to
enable Purchaser's designees to be elected or appointed to the Lowrance Board
as provided above to the fullest extent permitted by law.

  Employment Agreements. Prior to February 12, 2001, Lowrance shall enter into
employment agreements with Darrell J. Lowrance and Ronald G. Weber, each in a
form satisfactory to Cobra. In the case of the employment agreement of Ronald
G. Weber, such agreement shall be for a term of five years and shall provide
for salary no less favorable in the aggregate than currently provided to Mr.
Weber by Lowrance and benefits at the same level as similary situated officers
of Cobra. The employment agreements shall become effective upon consummation of
the Offer.

  Conditions Precedent. The respective obligations of each party to effect the
Merger are subject to the fulfillment at or prior to the Effective Time of the
following conditions: (i) the Merger Agreement shall have been approved and
adopted by the affirmative vote of the stockholders of Lowrance (unless the
vote of stockholders is not required under the DGCL) as required by the DGCL
and Lowrance's Certificate of Incorporation; (ii) Purchaser shall have
previously accepted for payment and paid for Shares pursuant to the

                                       28
<PAGE>

Offer, except that this condition shall not apply if Purchaser shall have
failed to purchase Shares pursuant to the Offer in breach of its obligations
under the Merger Agreement; and (iii) no court or other Governmental Entity (as
defined in the Merger Agreement) having jurisdiction over Lowrance or Cobra or
any of their respective subsidiaries shall have enacted, issued, promulgated,
enforced or entered any law, rule, regulation, executive order, decree,
injunction or other order (whether temporary, preliminary or permanent) which
is then in effect and has the effect of making the Merger illegal.

  Termination. The Merger Agreement provides that it may be terminated at any
time prior to the Effective Time, whether before or after approval of the
Merger Agreement by the stockholders of Lowrance:

  (a) by mutual written consent of Cobra and Lowrance;

  (b) by either Cobra or Lowrance: (i) if (x) as a result of the failure of
      any of the conditions to the Offer as set forth in Section 14 of this
      Offer to Purchase shall have terminated or expired in accordance with
      its terms without Purchaser having accepted for payment any Shares
      pursuant to the Offer or (y) Purchaser shall not have accepted for
      payment any Shares pursuant to the Offer prior to May 4, 2001 (provided
      that the right to terminate the Merger Agreement pursuant to this
      clause (b)(i) shall not be available to any party whose failure to
      perform any of its obligations under the Merger Agreement results in
      the failure of any such condition or if the failure of such condition
      results from facts or circumstances that constitute a breach of any
      representation or warranty under the Merger Agreement by such party),
      or (ii) if any Governmental Entity shall have issued an order, decree
      or ruling or taken any other action permanently enjoining, restraining
      or otherwise prohibiting the acceptance for payment of, or payment for,
      Shares pursuant to the Offer and such order, decree or ruling or other
      action shall have become final and nonappealable;

  (c) by Cobra or Purchaser prior to the purchase of Shares pursuant to the
      Offer in the event of a breach by Lowrance of any representation,
      warranty, covenant or other agreement contained in the Merger Agreement
      which (i) would give rise to the failure of the Offer conditions
      described in paragraph (e) or (f) of Section 14 and (ii) cannot be or
      has not been cured within 30 days after the giving of written notice to
      Lowrance;

  (d) by Cobra or Purchaser if either Cobra or Purchaser is entitled to
      terminate the Offer as a result of the occurrence of any event set
      forth in paragraph (d) of Section 14;

  (e) by Lowrance if the Lowrance Board reasonably determines that a Takeover
      Proposal constitutes a Superior Proposal and a majority of the Lowrance
      Board determines in its reasonable good faith judgment, after
      consultation with independent counsel, that failing to terminate the
      Merger Agreement would constitute a breach of its fiduciary duties
      under applicable law; provided, that it has complied with the notice
      and other provisions of the Merger Agreement relating to no
      solicitation of Takeover Proposals and it complies to the extent
      applicable with requirements of the Merger Agreement relating to
      payment of Expenses and the Termination Fee (each as defined below
      under "--Fees and Expenses"); and provided further that Lowrance may
      not terminate the Merger Agreement pursuant to this clause (e) unless
      and until 72 hours have elapsed following the delivery to Cobra of a
      written notice of such determination by the Lowrance Board;

  (f) by Lowrance, if (i) any of the representations or warranties of Cobra
      or Purchaser set forth in the Merger Agreement that are qualified as to
      materiality shall not be true and correct in any respect or any such
      representations or warranties that are not so qualified shall not be
      true and correct in any material respect or (ii) Cobra or Purchaser
      shall have failed to perform in any material respect any material
      obligation or to comply in any material respect with any material
      agreement or covenant of Cobra or Purchaser to be performed or complied
      with by it under the Merger Agreement and such untruth, incorrectness
      or failure cannot be or has not been cured within 30 days after the
      giving of written notice to Cobra or Purchaser, as applicable; or

  (g) by Lowrance, if the Offer has not been timely commenced in accordance
      with the Merger Agreement.

                                       29
<PAGE>

  In the event of a termination of the Merger Agreement by either Lowrance or
Cobra, the Merger Agreement shall become void (except for certain provisions
pertaining to the payment of certain expenses and fees and except for certain
confidentiality obligations of the parties) and there shall be no liability or
obligation on the part of Cobra, Purchaser or Lowrance or their respective
officers or directors other than for liability for any breach of a
representation or warranty contained in the Merger Agreement, the breach of any
covenant contained in the Merger Agreement or for fraud.

  Preferred Stock Redemption. Upon consummation of the Offer, Lowrance has
agreed to redeem all of its issued and outstanding shares of Preferred Stock at
a redemption price of $9.375 per share in cash (which represents a net
redemption price of $1.875 for each Share into which the shares of Preferred
Stock are convertible under certain circumstances).

  Fees and Expenses. Except as provided in the Merger Agreement, whether or not
the Merger is consummated, all costs and expenses incurred in connection with
the Offer, the Merger and the Merger Agreement and the transactions
contemplated thereby shall be paid by the party incurring such costs and
expenses.

  The Merger Agreement provides that Lowrance will pay, or cause to be paid, in
same day funds to Cobra the following amounts under the circumstances and at
the times set forth as follows:

  (i) if Cobra or the Purchaser terminates the Merger Agreement in accordance
      with the provisions described in clause (d) under "Termination" above,
      Lowrance shall pay the Expenses (as defined below) of Cobra and a
      $1,500,000 termination fee (the "Termination Fee") upon demand;

  (ii) if Lowrance terminates the Merger Agreement in accordance with the
       provision described in clause (e) under "Termination" above, Lowrance
       shall pay the Termination Fee within one business day following such
       termination and the Expenses of Cobra upon demand; or

  (iii) if any termination of the Merger Agreement occurs under the
        provisions described in clause (b) or (c) under "Termination" above,
        and at the time of any such termination a Takeover Proposal shall
        have been made (other than a Takeover Proposal made prior to the date
        of the Merger Agreement), if concurrently therewith or within 12
        months thereafter, (A) Lowrance enters into a merger agreement,
        acquisition agreement or similar agreement (including a letter of
        intent) with respect to a Takeover Proposal, or a Takeover Proposal
        is consummated, involving any party (1) with whom Lowrance had any
        discussions with respect to a Takeover Proposal, (2) to whom Lowrance
        furnished information with respect to or with a view to a Takeover
        Proposal or (3) who had submitted a proposal or expressed any
        interest publicly in a Takeover Proposal, in the case of each of
        clauses (1), (2) and (3), prior to such termination, or (B) Lowrance
        enters into a merger agreement, acquisition agreement or similar
        agreement (including a letter of intent) with respect to a Superior
        Proposal, or a Superior Proposal is consummated, then, in the case of
        either (A) or (B) above, Lowrance shall pay the Termination Fee and
        the Expenses of Cobra upon the earlier of the execution of such
        agreement or upon consummation of such Takeover Proposal or Superior
        Proposal; provided, that if the Merger Agreement is terminated by
        Lowrance pursuant to clause (b)(i) under "Termination" above and at
        the time of such termination the Financing Condition has not been
        satisfied, Lowrance shall not be obligated to pay the Termination Fee
        and the Expenses of Cobra under this clause (iii).

  For purposes of the Merger Agreement, "Expenses" means documented out-of-
pocket fees and expenses incurred or paid by or on behalf of Cobra in
connection with the Offer, the Merger or the consummation of any of the
transactions contemplated by the Merger Agreement, including all fees and
expenses of law firms, commercial banks, investment banking firms, accountants,
experts and consultants to Cobra, in an aggregate amount not in excess of
$500,000.

The Confidentiality Agreement.

  The following summary description of the confidentiality agreement entered
into between Cobra and Lowrance (the "Confidentiality Agreement") is qualified
in its entirety by reference to the agreement itself, which is an exhibit to
the Schedule TO that we filed with the SEC, which you may examine and copy as
set forth in Section 8.

                                       30
<PAGE>

  In July 2000, Lowrance and Cobra entered into a Confidentiality Agreement
pursuant to which Cobra agreed, in return for Lowrance's making available
certain non-public information, to use such information solely for the purpose
of evaluating the transaction between the parties and to not use such
information in any way directly or indirectly detrimental to Lowrance. Cobra
also agreed that it and its representatives will not disclose any of the
evaluation information unless the disclosure is made to a representative of
Cobra who needs to have such material for the sole purpose of evaluating the
transaction between the parties. Without the prior consent of Lowrance, Cobra
agreed that it and its representatives will not disclose to any other person
the fact that the materials have been provided to it or that discussions or
negotiations were taking place.

The Stockholder Agreements.

  The following summary description of the Stockholder Agreements is qualified
in its entirety by reference to the agreements themselves, which we have filed
as exhibits to the Schedule TO that we filed with the SEC, which you may
examine and copy as set forth in Section 9.

  Cobra and Purchaser entered into Stockholder Agreements dated as of January
4, 2001 (the "Stockholder Agreements") with each of the following stockholders
of Lowrance: Darrell J. Lowrance, Ronald G. Weber, Willard P. Britton and Peter
F. Foley (the "Tendering Stockholders"). Pursuant to the Stockholder
Agreements, each Tendering Stockholder has agreed that, (a) such Tendering
Stockholder will vote the Shares held by such Tendering Stockholder in favor of
the Merger and the Merger Agreement; (b) such Tendering Stockholder will vote
his or her Shares against (i) any other merger agreement or merger,
consolidation, combination, sale of substantial assets, reorganization,
recapitalization, dissolution, liquidation or winding up of or by Lowrance or
any other Takeover Proposal or (ii) any amendment of Lowrance's Certificate of
Incorporation or Bylaws or other proposal or transaction involving Lowrance,
which amendment or other proposal or transaction would in any manner impede,
frustrate, prevent or nullify the Merger, the Merger Agreement or any of the
other transactions contemplated by the Merger Agreement; (c) such Tendering
Stockholder will not (i) sell, transfer, pledge, assign or otherwise dispose
of, or enter into any contract, option or other arrangement (including any
profit sharing arrangement) with respect to the sale, transfer, pledge,
assignment or other disposition of, his or her Shares to any person other than
Purchaser or Purchaser's designee or (ii) enter into any voting arrangement,
whether by proxy, voting agreement or otherwise, in connection, directly or
indirectly, with any Takeover Proposal; (d) such Tendering Stockholder will
not, and will not permit any investment banker, attorney or other adviser or
representative of such Tendering Stockholder to, (i) directly or indirectly
solicit, initiate or encourage the submission of, any Takeover Proposal or (ii)
directly or indirectly participate in any discussions or negotiations
regarding, or furnish to any person any information with respect to, or take
any other action to facilitate any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Takeover Proposal;
and (e) the Tendering Stockholder will tender pursuant to the Offer and not
withdraw the Shares owned by such Tendering Stockholder. The Stockholder
Agreements terminate upon the earlier of (i) the Effective Time and (ii) the
valid termination of the Merger Agreement as set forth in the Stockholder
Agreements. In addition, Darrell J. Lowrance and Ronald G. Weber, the only
holders of Preferred Stock, have agreed that their shares of Preferred Stock
shall be redeemed by Lowrance at a redemption price of $9.375 per share,
effective immediately after the acceptance of shares for payment by Purchaser
pursuant to the Offer.

Statutory Requirements.

  In general, under the DGCL a merger of two Delaware corporations requires the
adoption of a resolution by the board of directors of each of the corporations
desiring to merge approving an agreement of merger containing provisions with
respect to certain statutorily specified matters and the approval of such
agreement of merger by the stockholders of each corporation by the affirmative
vote of the holders of a majority of all the outstanding shares of stock
entitled to vote on such merger. According to Lowrance's Certificate of
Incorporation, the Shares are the only securities of Lowrance which entitle the
holders thereof to voting rights.

  The DGCL also provides that if a parent company owns at least 90% of each
class of stock of a subsidiary that is outstanding and would be entitled to
vote on a merger, the parent company can effect a short-form

                                       31
<PAGE>

merger (a "Short-Form Merger") with that subsidiary without the action of the
other stockholders of the subsidiary. Accordingly, if as a result of the Offer
or otherwise Purchaser acquires or controls the voting power of at least 90% of
the Shares, Purchaser could, and intends (subject to the conditions to its
obligations to effect the Merger contained in the Merger Agreement) to, effect
the Merger without prior notice to, or any action by, any other stockholder of
Lowrance. Pursuant to the Merger Agreement, under certain circumstances we
could extend the Offer for a limited period of time in order to receive tenders
of at least 90% of the issued and outstanding Shares to enable us to effect a
Short-Form Merger. See "--The Merger Agreement--The Offer."

Appraisal Rights.

  No appraisal rights are available in connection with the Offer. However, if
the Merger is consummated, any holder of Shares at the Effective Time will have
certain rights under the DGCL to dissent and demand appraisal of, and payment
in cash of fair value of, their Shares. Such rights, if the statutory
procedures were complied with, could lead to a judicial determination of the
fair value (excluding any element of value arising from the accomplishment or
expectation of the Merger) required to be paid in cash to such dissenting
holders for their Shares. Any such judicial determination of fair value of
Shares could be based upon considerations other than, or in addition to, the
price paid in the Offer and the market value of the Shares, including asset
values and the investment value of the Shares. The value so determined could be
more or less than the purchase price per Share pursuant to the Offer or the
consideration per Share to be paid in the Merger.

  In addition, several decisions by Delaware courts have held that, in certain
instances, a controlling stockholder of a corporation involved in a Merger has
a fiduciary duty to the other stockholders that requires the Merger to be fair
to such other stockholders. In determining whether a Merger is fair to minority
stockholders, the Delaware courts have considered, among other things, the type
and amount of consideration to be received by the stockholders and whether
there were fair dealings among the parties. Although the remedies of rescission
or other damages are possible in an action challenging a Merger as a breach of
fiduciary duty, decisions of the Delaware courts have indicated that in most
cases the remedy available in a Merger that is found not to be "fair" to
minority stockholders is a damages remedy based on essentially the same
principles as an appraisal.

  APPRAISAL RIGHTS CANNOT BE EXERCISED AT THIS TIME. STOCKHOLDERS WHO WILL BE
ENTITLED TO APPRAISAL RIGHTS IN CONNECTION WITH THE MERGER WILL RECEIVE
ADDITIONAL INFORMATION CONCERNING APPRAISAL RIGHTS AND THE PROCEDURES TO BE
FOLLOWED IN CONNECTION THEREWITH BEFORE SUCH STOCKHOLDERS HAVE TO TAKE ANY
ACTION RELATING THERETO.

  STOCKHOLDERS WHO SELL SHARES IN THE OFFER WILL NOT BE ENTITLED TO EXERCISE
APPRAISAL RIGHTS WITH RESPECT THERETO BUT, RATHER, WILL RECEIVE THE PRICE PAID
IN THE OFFER THEREFOR.

Rule 13e-3.

  The SEC has adopted Rule 13e-3 under the Exchange Act which is applicable to
certain "going private" transactions and which may, under certain
circumstances, be applicable to the Merger or another business combination in
which Purchaser seeks to acquire the remaining Shares not held by it following
the purchase of Shares pursuant to the Offer. Purchaser believes, however, that
Rule 13e-3 will not be applicable to the Merger if the Merger is consummated
within one year after the termination of the Offer at the Offer Price. If
applicable, Rule 13e-3 requires, among other things, that certain financial
information concerning Lowrance and certain information relating to the
fairness of the proposed transaction and the consideration offered to minority
stockholders in such transaction be filed with the SEC and disclosed to
stockholders prior to consummation of the transaction.

                                       32

Plans for Lowrance After the Offer and the Merger.

  Pursuant to the Merger Agreement, upon completion of the Offer, Cobra and
Purchaser intend to effect the Merger in accordance with the Merger Agreement.
See "--The Merger Agreement."

  Except as otherwise described in this Offer to Purchase, Cobra has no current
plans or proposals or negotiations which relate to or would result in: (i)
other than the Merger, an extraordinary corporate transaction, such as a
merger, reorganization or liquidation involving Lowrance; (ii) any purchase,
sale or transfer of a material amount of assets of Lowrance; (iii) any change
in the management of Lowrance or any change in any material term of the
employment contract of any executive officer of Lowrance; or (iv) any other
material change in Lowrance's corporate structure or business.

  Nevertheless, Cobra may initiate a review of Lowrance and its assets,
corporate structure, capitalization, operations, properties, policies,
management and personnel to determine what changes, if any, would be desirable
following the Merger in order best to organize and integrate the activities of
Lowrance and Cobra.

12. Source and Amount of Funds.

   The Offer is conditioned upon receipt by Cobra of proceeds of debt financing
in an amount necessary to consummate the transactions contemplated by the
Merger Agreement on terms satisfactory to Cobra in its sole discretion. Cobra
estimates that the total amount of funds required to purchase all of the Shares
pursuant to the Offer, to refinance the outstanding indebtedness of Lowrance,
and to pay fees and expenses related to the transaction will be approximately
$58.2 million.

  Cobra plans to obtain the necessary funds under the Credit Facility (as
defined below) and the Senior Subordinated Notes (as defined below).

  Credit Facility. Cobra has executed a financing term sheet (the "Credit
Facility Term Sheet") with LaSalle Bank National Association ("LaSalle"),
General Electric Capital Corporation ("GE Capital") and BT Commercial
Corporation ("BTCC") in which LaSalle, GE Capital, BTCC (collectively, the
"Agents") and other lenders acceptable to the Agents would provide financing in
an aggregate principal amount of up to $85 million (the "Credit Facility").
Although the Agents have committed to provide the entire Credit Facility, the
Agents may assemble a syndicate of financial institutions prior to the initial
funding under the Credit Facility. The terms of the definitive agreement
providing for the Credit Facility (the "Loan Agreement") have not yet been
finalized. The following is a summary of the anticipated principal terms of the
Credit Facility based upon the Credit Facility Term Sheet. This summary is
subject to finalizing the Loan Agreement and is qualified in its entirety by
reference to the Credit Facility Term Sheet, which is filed as an exhibit to
the Schedule TO that we filed with the SEC.

  The Credit Facility consists of a revolving loan facility (the "Revolving
Facility") under which loans may be borrowed, repaid and reborrowed by Cobra or
Lowrance from time to time in an aggregate amount of up to $65 million, with
the amount available for borrowing at any time being limited to an amount equal
to the sum of up to 75% of eligible accounts receivable of Cobra and Lowrance,
up to 60% of eligible inventory of Cobra and Lowrance (excluding goods in
Mexico and Australia) valued at the lower of cost or market and up to 50% of
eligible finished goods inventory purchased by Cobra and Lowrance utilizing
documentary letters of credit less reserves. The amount outstanding under the
Revolving Facility will include $25 million that is available for documentary
letters of credit. The Credit Facility also contains a term loan (the "Term
Loan") of up to $20 million.

  The Credit Facility will mature in the lesser of five years or six months
prior to the first principal payment required under the Subordinated Debt
Agreement (as defined below). The Term Loan will be repaid in quarterly
payments of principal. If the Revolving Facility is terminated, the Term Loan
will become immediately due and payable.

                                       33
<PAGE>

  Borrowings under the Credit Facility will bear interest based upon, at
Cobra's option, (i) absent a default, 1, 2 or 3-month reserve-adjusted London
Interbank Offered Rate plus 3.250% per annum or (ii) a floating rate at the
higher of the prime rate or .50% per annum over the Federal funds rate plus
0.875% per annum.

  Borrowings under the Credit Facility will be secured by a first priority
security interest in all existing and after-acquired assets of Cobra and
Lowrance and their subsidiaries and a pledge of all of the issued and
outstanding capital stock of Cobra's subsidiaries (including Lowrance). Each of
Cobra and Lowrance will guarantee the other's obligations under the Credit
Facility.

  Cobra may terminate the Revolving Facility or prepay the Term Loan, and, if
Cobra chooses to do so, will pay a prepayment fee of 1.5% of the committed
amount of the Revolving Facility and the amount prepaid on the Term Loan in the
first year and 0.5% of such amounts in the second year and will incur no
prepayment fees thereafter. The amounts borrowed under the Credit Facility are
subject to mandatory prepayment upon certain dispositions of assets, upon
certain sales of equity or issuance of debt and for 65% of annual excess cash
(as defined in the Loan Agreement).

  The Credit Facility will include a closing fee of 2% of the $85 million
Credit Facility amount, one-half of which is due and payable upon the signing
of a commitment letter and the other one-half of which is due and payable upon
the closing of the Credit Facility. A documentary letter of credit fee of
1.625% per annum will accrue on the face amount of the letters of credit issued
pursuant to the Credit Facility, payable monthly in arrears, plus any charges
assessed by the issuing bank. A facility fee will accrue on the Revolving
Facility at a rate of 0.50% on the average unused daily balance of the
Revolving Facility, payable monthly in arrears. Cobra will also pay the Agents
an annual Agents' fee of $50,000 per annum, reimburse certain expenses and
provide certain indemnities, all of which Cobra believes to be customary for
commitments of this type.

  The Loan Agreement will contain conditions precedent, representations and
warranties, covenants (including financial covenants), events of default and
other provisions customary for such financings.

  The Agents' agreement to provide the Credit Facility is conditioned on, among
other things: Cobra's procurement of at least $15 million of subordinated debt
with terms and conditions that are satisfactory to the Agents; satisfactory
completion by the Agents of all business, environmental and legal due
diligence; the signing of the Loan Agreement on or before January 31, 2001; the
absence of a material adverse change in the business, financial or other
condition of Cobra or Lowrance or both of them taken as a whole, the industry
in which Cobra or Lowrance operates, the collateral which will be subject to
the security interest granted to the Agents or in the prospects or projections
of Cobra or Lowrance; the absence of any litigation which, if successful, would
have a material adverse impact on Cobra or Lowrance or both of them taken as a
whole, their respective businesses or on their ability to repay the loans, or
which would challenge the Offer, the Merger or the Credit Facility; the
absence, since Cobra's and Lowrance's last audited financial statements, of a
material increase in the liabilities, liquidated or contingent, of Cobra or
Lowrance, or both of them taken as a whole; the absence, since December 14,
2000, of any change in loan syndication, financial or capital market conditions
generally that in the Agents' judgment would materially impair syndication of
the financing; total funded senior debt (including capital leases) of Cobra and
Lowrance not exceeding 2.75 times trailing twelve month earnings before taxes,
depreciation and amortization; and minimum excess collateral at closing of at
least $8 million.

  Senior Subordinated Notes. Cobra has also executed a financing term sheet
(the "Subordinated Notes Term Sheet") with American Capital Strategies, Ltd.
("American Capital") pursuant to which American Capital has agreed to provide
Cobra $15 million in financing in exchange for senior secured subordinated
notes of Cobra in the aggregate principal amount of $15 million (the
"Subordinated Notes"). The terms of the agreement providing for the
Subordinated Notes (the "Subordinated Debt Agreement") have not yet been
finalized. The following is a summary of the anticipated principal terms of the
Subordinated Debt Agreement based upon the Subordinated Notes Term Sheet. This
summary is subject to finalizing the Subordinated Debt Agreement and is
qualified in its entirety by reference to the Subordinated Notes Term Sheet,
which is filed as an exhibit to the Schedule TO that we filed with the SEC.

                                       34
<PAGE>

  The Subordinated Notes will mature on February 28, 2009 (the "Maturity
Date"). The Subordinated Notes will be repaid over equal monthly payments of
principal commencing on the first month following the fifth anniversary of the
closing of the Subordinated Debt Agreement such that the Subordinated Notes are
fully repaid on the Maturity Date.

  The Subordinated Notes will bear monthly interest in arrears on the first
business day of each month at a fixed rate equal to 14% per annum in cash plus
4.50% per annum payable in kind ("PIK Interest") due on the Maturity Date.

  Cobra paid American Capital a processing fee of $75,000 upon execution of the
Subordinated Notes Term Sheet and will pay American Capital a processing fee at
the closing of the Subordinated Debt Agreement of $375,000.

  Cobra may prepay the Subordinated Notes in multiples of $100,000, and, if
Cobra chooses to do so, will pay a prepayment fee in the first year of 4% of
the amount prepaid, 3% in the second year of the amount prepaid, 1% in the
third year of the amount prepaid and will incur no prepayment fee thereafter.
Mandatory prepayments of the Subordinated Notes will be required upon a change
in control, merger, consolidation or similar combination involving Cobra, or
sale of a material portion of Cobra's assets or other similar transaction, or
upon a change in the position of James R. Bazet, currently the president and
chief executive officer of Cobra. Mandatory prepayments will be subject to the
same prepayment fees as discussed above, in addition to default interest rates
if applicable.

  American Capital will have the right to convert the accumulated PIK Interest
portion of the Subordinated Notes into 350,000 shares of common stock of Cobra
(the "Conversion Option"). The Conversion Option will be exercisable any time
after the third anniversary of the closing of the Subordinated Debt Agreement.
American Capital may also deliver for mandatory redemption at fair market value
(determined at the market price or by appraisal) by Cobra any shares of common
stock of Cobra received in connection with the Conversion Option at any time
after the earlier to occur of: (i) the fifth anniversary of the closing of the
Subordinated Debt Agreement; (ii) sale of Cobra or a material portion of its
assets or (iii) repayment in full of the Subordinated Notes. The Conversion
Option will expire on the tenth anniversary of closing. The Conversion Option
will also include registration rights, anti-dilution rights and pre-emptive
rights customary for such financing.

  The Subordinated Notes will be secured by a security interest in all of
Cobra's assets, subordinated only to the security interests of the lenders
under the Credit Facility.

  The Subordinated Debt Agreement will contain conditions precedent,
representations and warranties, covenants (including financial covenants),
events of default and other provisions customary for such financing.

  American Capital's agreement to purchase the Subordinated Notes is
conditioned on, among other things: satisfactory completion by American Capital
of all business, legal and accounting due diligence; execution of the
Subordinated Debt Agreement; the absence of a material adverse change in the
business or financial condition of Cobra, its business or the capital markets
after the date of the Subordinated Notes Term Sheet; execution of the Loan
Agreement; and Cobra having no less than $65.1 million of working capital and
no less than $47 million of equity at closing.

  In addition to providing the funds required to consummate the purchase of
Lowrance, the proceeds of the Credit Facility and the Subordinated Notes will
also be used to refinance Cobra's existing indebtedness.

  It is anticipated that the indebtedness incurred through borrowings under the
Credit Facility and the Subordinated Debt Agreement will be repaid from funds
generated internally by Cobra and its subsidiaries, including Lowrance and its
subsidiaries, and from other sources that may include the proceeds of the
private or public sale of debt or equity securities. No final decisions have
been made concerning the method Cobra will

                                       35
<PAGE>

employ to repay such indebtedness. Such decisions when made will be based on
Cobra's review from time to time of the advisability of particular actions, as
well as on prevailing interest rates and financial and other economic
conditions.

13. Dividends and Distributions.

  The Merger Agreement provides that Lowrance shall not, without the prior
written consent of Cobra, (i) declare, set aside or pay any dividends on, or
make any other actual, constructive or deemed distributions in respect of, any
of its capital stock, or otherwise make any payments to its stockholders in
their capacity as such, (ii) split, combine or reclassify any of its capital
stock or issue or authorize the issuance of any other securities in respect of,
in lieu of or in substitution for shares of its capital stock, or (iii)
purchase, redeem or otherwise acquire any Shares or any other securities
thereof or any rights, warrants or options to acquire any such Shares or other
securities.

14. Conditions of the Offer.

  Conditions to the Offer. Notwithstanding any other term of the Offer or the
Merger Agreement, Purchaser shall not be required to accept for payment or,
subject to any applicable rules and regulations of the SEC, including Rule 14e-
1(c) under the Exchange Act (relating to Purchaser's obligation to pay for or
return tendered Shares after the termination or withdrawal of the Offer), to
pay for any Shares tendered pursuant to the Offer unless (i) the Minimum
Condition shall have been satisfied and (ii) the Financing Condition shall have
been satisfied. Furthermore, notwithstanding any other term of the Offer or the
Merger Agreement, Purchaser shall not be required to accept for payment or,
subject as aforesaid, to pay for any Shares not theretofore accepted for
payment or paid for, and may terminate the Offer if, at any time on or after
the date of the Merger Agreement and before the acceptance of such Shares for
payment or the payment therefor, any of the following conditions exist (other
than as a result of any action or inaction of Cobra or any of its subsidiaries
that constitutes a breach of the Merger Agreement):

  (a) there shall be threatened or pending by any Governmental Entity (as
      defined in the Merger Agreement) any suit, action or proceeding (i)
      challenging the acquisition by Cobra or Purchaser of any Shares under
      the Offer, seeking to restrain or prohibit the making or consummation
      of the Offer or the Merger or the performance of any of the other
      transactions contemplated by the Merger Agreement or the Stockholder
      Agreements (including the voting provisions thereunder), or seeking to
      obtain from Lowrance, Cobra or Purchaser any damages that are material
      in relation to Lowrance and its subsidiaries taken as a whole, (ii)
      seeking to prohibit or materially limit the ownership or operation by
      Lowrance, Cobra or any of their respective subsidiaries of a material
      portion of the business or assets of Lowrance and its subsidiaries, or
      Cobra and its subsidiaries, taken as a whole, or to compel Lowrance or
      Cobra to dispose of or hold separate any material portion of the
      business or assets of Lowrance and its subsidiaries, or Cobra and its
      subsidiaries, taken as a whole, as a result of the Offer or any of the
      other transactions contemplated by the Merger Agreement or the
      Stockholder Agreements, (iii) seeking to impose material limitations on
      the ability of Cobra or Purchaser to acquire or hold, or exercise full
      rights of ownership of, any Shares to be accepted for payment pursuant
      to the Offer, including the right to vote such Shares on all matters
      properly presented to the stockholders of Lowrance, (iv) seeking to
      prohibit Cobra or any of its subsidiaries from effectively controlling
      in any material respect any material portion of the business or
      operations of Lowrance or its subsidiaries or (v) which otherwise is
      reasonably likely to have a Material Adverse Effect (as defined below)
      on Lowrance, or there shall be pending by any other person any suit,
      action or proceeding which would have a Material Adverse Effect on
      Lowrance;

  (b) there shall be enacted, entered, enforced, promulgated or deemed
      applicable to the Offer or the Merger by any Governmental Entity any
      statute, rule, regulation, judgment, order or injunction that is
      reasonably likely to result, directly or indirectly, in any of the
      consequences referred to in clauses (i) through (v) of paragraph (a)
      above;

                                       36
<PAGE>

  (c) there shall have occurred any Material Adverse Change (as defined
      below) with respect to Lowrance;

  (d)  (i) the Lowrance Board or any committee thereof shall have withdrawn
      or modified in a manner adverse to Cobra or Purchaser its approval or
      recommendation of the Offer, the Merger or the Merger Agreement, or
      approved or recommended any Takeover Proposal or (ii) the Lowrance
      Board or any committee thereof shall have resolved to take any of the
      foregoing actions;

  (e) the representations and warranties of Lowrance set forth in the Merger
      Agreement shall not be true and correct in each case at the date of the
      Merger Agreement and at the scheduled or extended expiration of the
      Offer unless the inaccuracies (without giving effect to any materiality
      or Material Adverse Effect qualifications or exceptions contained
      therein) under such representations and warranties, taking all the
      inaccuracies under such representations and warranties together in
      their entirety, do not, individually or in the aggregate, result in a
      Material Adverse Effect on Lowrance;

  (f) Lowrance shall have failed to perform in any material respect any
      obligation or to comply in any material respect with any agreement or
      covenant of Lowrance to be performed or complied with by it under the
      Merger Agreement;

  (g) any person or "group" (as defined in Section 13(d)(3) of the Exchange
      Act), other than Cobra, Purchaser or their affiliates or any group of
      which any of them is a member, shall have acquired or announced its
      intention to acquire beneficial ownership (as determined pursuant to
      Rule 13d-3 promulgated under the Exchange Act) of 25% or more of the
      Shares;

  (h) there shall have occurred and be continuing (i) any general suspension
      of trading in, or limitation on prices for, securities on a national
      securities exchange in the United States (excluding any coordinated
      trading halt triggered solely as a result of a specified decrease in a
      market index), (ii) a declaration of a banking moratorium or any
      suspension of payments in respect of banks in the United States, (iii)
      any limitation (whether or not mandatory) by any Governmental Entity
      on, or other event that materially adversely affects, the extension of
      credit by banks or other lending institutions or (iv) a commencement of
      a war or armed hostilities or other national or international calamity
      directly or indirectly involving the United States which in any case is
      reasonably expected to have a Material Adverse Effect on Lowrance or to
      materially adversely affect Cobra's or Purchaser's ability to complete
      the Offer and/or the Merger or materially delay the consummation of the
      Offer and/or the Merger; or

  (i) the Merger Agreement shall have been terminated in accordance with its
      terms.

  "Material Adverse Change" or "Material Adverse Effect" means any change or
effect that is or could reasonably be expected (as far as can be foreseen at
the time) to be materially adverse to the business, operations, properties or
results of operations, financial projections or forecasts, or the business
prospects and condition (financial or otherwise), with all such matters being
considered in the aggregate, of Lowrance and its subsidiaries, taken as a
whole.

  The foregoing conditions are for the sole benefit of Cobra and Purchaser and
may, subject to the terms of the Merger Agreement, be waived by Cobra and
Purchaser in whole or in part at any time and from time to time in their sole
discretion. The failure by Cobra or Purchaser at any time to exercise any of
the foregoing rights shall not be deemed a waiver of any such right, the waiver
of any such right with respect to particular facts and circumstances shall not
be deemed a waiver with respect to any other facts and circumstances and each
such right shall be deemed an ongoing right that may be asserted at any time
and from time to time.

15. Legal Matters; Required Regulatory Approvals.

  Except as set forth in this Offer to Purchase, based on our review of
publicly available filings by Lowrance with the SEC and other information
regarding Lowrance, we are not aware of any licenses or regulatory permits that
appear to be material to the business of Lowrance and its subsidiaries, taken
as a whole, and that might be adversely affected by our acquisition of Shares
in the Offer. In addition, except as described

                                       37
<PAGE>

in this Offer to Purchase, we are not aware of any filings, approvals or other
actions by or with any governmental authority or administrative or regulatory
agency that would be required for our acquisition or ownership of the Shares.
Should any such approval or other action be required, we expect to seek such
approval or action, except as described below under "State Takeover Laws."
Should any such approval or other action be required, we cannot be certain that
we would be able to obtain any such approval or action without substantial
conditions or that adverse consequences might not result to Lowrance's
business, or that certain parts of Lowrance's, Cobra's, or any of their
respective subsidiaries' businesses might not have to be disposed of or held
separate in order to obtain such approval or action. In that event, we may not
be required to purchase any Shares in the Offer. See Introduction and Section
14 for a description of the conditions to the Offer.

  State Takeover Laws. Lowrance is incorporated under the laws of the State of
Delaware. In general, Section 203 of the DGCL ("Section 203") prevents an
"interested stockholder" (including a person who owns or has the right to
acquire 15% or more of a corporation's outstanding voting stock) from engaging
in a "business combination" (defined to include mergers and certain other
actions) with a Delaware corporation for a period of three years following the
date such person became an interested stockholder unless, among other things,
the "business combination" is approved by the Board of Directors of such
corporation prior to such date. The Lowrance Board has approved the Offer and
the Merger. Accordingly, Section 203 is inapplicable to the Offer and the
Merger. A number of other states have adopted laws and regulations applicable
to attempts to acquire securities of corporations which are incorporated, or
have substantial assets, stockholders, principal executive offices or principal
places of business or whose business operations otherwise have substantial
economic effects in such states. In 1982, the Supreme Court of the United
States, in Edgar v. Mite Corp., invalidated on constitutional grounds the
Illinois Business Takeovers Statute, which as a matter of state securities law
made takeovers of corporations meeting certain requirements more difficult. The
reasoning in that decision is likely to apply to certain other state takeover
statutes. In 1987, however, in CTS Corp. v. Dynamics Corp. of America, the
Supreme Court of the United States held that the State of Indiana could as a
matter of corporate law and, in particular, those aspects of corporate law
concerning corporate governance, constitutionally disqualify a potential
acquirer from voting on the affairs of a target corporation without the prior
approval of the remaining stockholders, as long as those laws were applicable
only under certain conditions. Subsequently, in TLX Acquisition Corp. v. Telex
Corp., a federal district court in Oklahoma ruled that the Oklahoma statutes
were unconstitutional insofar as they apply to corporations incorporated
outside Oklahoma, because they would subject those corporations to inconsistent
regulations. Similarly, in Tyson Foods, Inc. v. McReynolds, a federal district
court in Tennessee ruled that four Tennessee takeover statutes were
unconstitutional as applied to corporations incorporated outside Tennessee.
This decision was affirmed by the United States Court of Appeals for the Sixth
Circuit. In December 1988, a federal district court in Florida held, in Grand
Metropolitan PLC v. Butterworth, that the provisions of the Florida Affiliated
Transactions Act and Florida Control Share Acquisition Act were
unconstitutional as applied to corporations incorporated outside of Florida.

  We have not attempted to comply with any state takeover statutes in
connection with the Offer or the Merger. We reserve the right to challenge the
validity or applicability of any state law allegedly applicable to the Offer or
the Merger, and nothing in this Offer to Purchase nor any action that we take
in connection with the Offer is intended as a waiver of that right. In the
event that it is asserted that one or more takeover statutes apply to the Offer
or the Merger, and it is not determined by an appropriate court that the
statutes in question do not apply or are invalid as applied to the Offer or the
Merger, as applicable, we may be required to file certain documents with, or
receive approvals from, the relevant state authorities, and we might be unable
to accept for payment or purchase Shares tendered in the Offer or be delayed in
continuing or consummating the Offer. In that case, we may not be obligated to
accept for purchase, or pay for, any Shares tendered. See Section 14.

  Antitrust. Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act"), and the related rules and regulations that have been
issued by the Federal Trade Commission (the "FTC"), certain acquisition
transactions may not be consummated until certain information and documentary

                                       38
<PAGE>

material have been furnished for review by the FTC and the Antitrust Division
of the Department of Justice and certain waiting period requirements have been
satisfied. On December 21, 2000, the President of the United States signed into
law amendments to the HSR Act that increased the applicable minimum "size of
transaction" reportability threshold, based on the value of the voting
securities and/or assets being acquired, from $15 million to $50 million, and
made other changes to the HSR Act. The amendments will become effective on
February 1, 2001, which is prior to the Expiration Date. Consequently, the
requirements of the HSR Act that will then exist as a result of the newly-
enacted amendments will not be applicable to our acquisition of Shares in the
Offer and the Merger.

16. Fees and Expenses.

  We have retained Morrow & Co., Inc. as Information Agent in connection with
the Offer. The Information Agent may contact holders of Shares by mail,
telephone, telex, telegraph and personal interview and may request brokers,
dealers and other nominee stockholders to forward material relating to the
Offer to beneficial owners of Shares. We will pay the Information Agent
reasonable and customary compensation for these services in addition to
reimbursing the Information Agent for its reasonable out-of-pocket expenses. We
have agreed to indemnify the Information Agent against certain liabilities and
expenses in connection with the Offer, including certain liabilities under the
federal securities laws.

  In addition, we have retained American Stock Transfer and Trust Company as
the Depositary. We will pay the Depositary reasonable and customary
compensation for its services in connection with the Offer, will reimburse the
Depositary for its reasonable out-of-pocket expenses and will indemnify the
Depositary against certain liabilities and expenses, including certain
liabilities under the federal securities laws.

  Except as set forth above, we will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of Shares pursuant to the
Offer. We will reimburse brokers, dealers, commercial banks and trust companies
and other nominees, upon request, for customary clerical and mailing expenses
incurred by them in forwarding offering materials to their customers.

17. Miscellaneous.

  We are not aware of any jurisdiction where the making of the Offer is
prohibited by any administrative or judicial action pursuant to any valid state
statute. If we become aware of any valid state statute prohibiting the making
of the Offer or the acceptance of the Shares, we will make a good faith effort
to comply with that state statute. If, after a good faith effort, we cannot
comply with the state statute, we will not make the Offer to, nor will we
accept tenders from or on behalf of, the holders of Shares in that state. In
any jurisdiction where the securities, blue sky or other laws require the Offer
to be made by a licensed broker or dealer, the Offer shall be deemed to be made
on behalf of Purchaser by one or more registered brokers or dealers licensed
under the laws of such jurisdiction.

  We have filed with the SEC a Tender Offer Statement on Schedule TO, together
with exhibits, furnishing certain additional information with respect to the
Offer, and may file amendments to our Schedule TO. Our Schedule TO and any
exhibits or amendments may be examined and copies may be obtained from the SEC
in the same manner as described in Section 8 with respect to information
concerning Lowrance.

  We have not authorized any person to give any information or to make any
representation on our behalf not contained in this Offer to Purchase or in the
Letter of Transmittal and, if given or made, you should not rely on any such
information or representation as having been authorized.

  Neither the delivery of the Offer to Purchase nor any purchase pursuant to
the Offer will under any circumstances create any implication that there has
been no change in the affairs of Cobra, Purchaser, Lowrance or any of their
respective subsidiaries since the date as of which information is furnished or
the date of this Offer to Purchase.
