Exhibit 20.3

NOTICE OF MERGER AND APPRAISAL RIGHTS

To:

Former Stockholders of
Next Level Communications, Inc.

Dear Former Stockholder:

In accordance with Section 262 of the General Corporation Law of the State of Delaware (the "DGCL"), you are hereby notified that the Board of Directors and sole stockholder of NL Merger Corporation ("NLMC"), a Delaware corporation and wholly owned subsidiary of Motorola, Inc., a Delaware corporation ("Motorola"), has approved the merger (the "Merger") of NLMC with and into Next Level Communications, Inc., a Delaware corporation ("Next Level"), pursuant to Section 253 of the DGCL and that the Merger became effective on April , 2003 (the "Effective Date").

Upon effectiveness of the Merger, (i) Next Level became a wholly owned subsidiary of Motorola, and (ii) each share of common stock of Next Level, par value $.01 per share (a "Next Level Common Stock") outstanding at the effective time of the Merger (other than shares held by Motorola or its wholly owned subsidiaries or by stockholders exercising appraisal rights) automatically converted into the right to receive $1.18 in cash.

In accordance with Section 262 of the DGCL, you are hereby notified that the record holders of shares of Next Level Common Stock (the "Shares") at the Effective Date of the Merger (the "Former Stockholders") are entitled to have their Shares appraised by the Court of Chancery of the State of Delaware and to receive payment of the fair value of such Shares together with a fair rate of interest, if any, as determined by such court. In determining the fair value of the Shares, the Delaware court would not consider any benefits arising from the Merger. The following is a summary of certain of the provisions of Section 262 of the DGCL and is qualified in its entirety by reference to the full text of Section 262, a copy of which is attached to this notice as Exhibit A.

Any Former Stockholder entitled to appraisal rights has the right, within 20 days after the date of mailing of this notice, to demand in writing from Next Level an appraisal of his or her Shares. Such demand will be sufficient if it reasonably informs Next Level of the identity of the Former Stockholder and of the Former Stockholder's intent to demand an appraisal of the fair value of his or her Shares. Failure to make such demand on a timely basis would foreclose a Former Stockholder's right to appraisal.

Only a holder of record of Shares at the Effective Date of the Merger is entitled to assert appraisal rights for the Shares registered in that holder's name. A demand for appraisal should be executed by or on behalf of the holder of record fully and correctly, as the holder's name appears on the holder's stock certificates. Holders of Shares who hold their shares in brokerage accounts or other nominee forms and wish to exercise appraisal rights should consult with their brokers to determine the appropriate procedures for the making of a demand for appraisal by such nominee. All written demands for appraisal of the Shares should be sent or delivered to Secretary, Next Level Communications, Inc., c/o Motorola, Inc. 1303 E. Algonquin Road, Schaumburg, Illinois 60196, Attention: Michelle M. Warner, Esq. so as to be received within the 20 days after the mailing of this notice.

If the Shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, execution of the demand should be made in that capacity, and if the Shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including one or more joint owners, may execute a demand for appraisal on behalf of a holder of record; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, the agent is agent for such owner or owners.

A record holder such as a broker holding Shares as nominee for several beneficial owners may exercise appraisal rights with respect to the Shares held for one or more beneficial owners while not exercising such rights with respect to the Shares held for other beneficial owners; in such case, the written demand should set forth the number of Shares as to which appraisal is sought. Where no number of Shares is expressly mentioned, the demand will be presumed to cover all Shares held in the name of the record owner.

Within 120 calendar days after the Effective Date of the Merger, Next Level, or any Former Stockholder entitled to appraisal rights under Section 262 of the DGCL who has complied with the foregoing procedures, may file a petition in the Delaware Court of Chancery demanding a determination of the fair value of the Shares of all such Former Stockholders. Next Level is not under any obligation, and has no present intention, to file a petition with respect to the appraisal of the fair value of the Shares. Accordingly, it is the obligation of the Former Stockholders to initiate all necessary action to perfect their appraisal rights within the time prescribed in Section 262 of the DGCL.

Within 120 calendar days after the Effective Date of the Merger, any Former Stockholder who has complied with the requirements for exercise of appraisal rights will be entitled, upon written request, to receive from Next Level a statement setting forth the aggregate number of Shares with respect to which demands for appraisal have been received and the aggregate number of holders of such Shares. Such statement must be mailed within 10 calendar days after a written request therefor has been received by Next Level or within 10 calendar days after the expiration of the period for the delivery of demands for appraisal, whichever is later.

If a petition for an appraisal is timely filed, after a hearing on such petition, the Delaware Court of Chancery will determine the Former Stockholders entitled to appraisal rights and will appraise the fair value of the Shares, without considering any benefits arising from the Merger, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. Holders considering seeking appraisal should be aware that the fair value of their Shares as determined under Section 262 of the DGCL could be more than, the same as or less than the Merger consideration of $1.18 per Share that they would otherwise receive if they did not seek appraisal of their Shares. The Delaware Supreme Court has stated that "proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court" should be considered in the appraisal proceedings. The Court will also determine the amount of interest, if any, to be paid upon the amounts to be received by persons whose Shares have been appraised. The costs of the action may be determined by the Court and taxed upon the parties as the Court deems equitable. The Court may also order that all or a portion of the expenses incurred by any holder of Shares in connection with an appraisal, including, without limitation, reasonable attorneys' fees and the fees and expenses of experts used in the appraisal proceeding, be charged pro rata against the value of all the Shares entitled to appraisal.

The Court may require Former Stockholders who have demanded an appraisal and who hold Shares represented by certificates to submit their certificates for Shares to the Court for notation thereon of the pendency of the appraisal proceedings. If any Former Stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such Former Stockholder.

Any Former Stockholder who has duly demanded an appraisal in compliance with Section 262 of the DGCL will not be entitled to vote the Shares subject to such demand for any purpose or to be entitled to the payment of dividends or other distributions on those Shares.

If any Former Stockholder who demands appraisal of Shares under Section 262 of the DGCL fails to perfect, or effectively withdraws or loses, the right to appraisal, as provided in the DGCL, the Shares of such holder will be converted into the right to receive the Merger consideration of $1.18 per Share, without interest. A Former Stockholder will fail to perfect, or effectively lose, the right to appraisal if no petition is filed within 120 calendar days after the Effective Date of the Merger. A Former Stockholder may withdraw a demand for appraisal by delivering to Next Level a written withdrawal of the demand for appraisal and acceptance of the Merger, except that any such attempt to withdraw made more than 60 calendar days after the Effective Date of the Merger will require the written

approval of Next Level. Once a petition for appraisal has been filed, such appraisal proceeding may not be dismissed as to any Former Stockholder without the approval of the Court.

The foregoing summary does not purport to be a complete statement of the procedures to be followed by Former Stockholders desiring to exercise their dissenting appraisal rights and is qualified in its entirety by express reference to Section 262 of the DGCL, the full text of which is attached hereto as Exhibit A. Former Stockholders are urged to read Exhibit A in its entirety since failure to comply with the procedures set forth therein will result in the loss of appraisal rights.

EXHIBIT A

SECTION 262 OF THE GENERAL CORPORATION LAW
OF THE STATE OF DELAWARE

§ 262 Appraisal rights.

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of § 251 of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to § § 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228 or § 253 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be

not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
