 AGREEMENT: 
  
 NOW, THEREFORE, in consideration of the foregoing
and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows: 
  

 1 

	1.	Effectiveness and Termination of Prior Agreements. 

  

	 	(a)	This Agreement shall become effective only upon the consummation (closing and funding) of the Qualified Public Offering on or prior to September 30, 2004 (the “Effective
Time”). If the Qualified Public Offering has not been closed and funded on or prior to September 30, 2004, this Agreement (including the proxies granted pursuant to Section 2 hereof) shall automatically terminate and be of no further force
or effect. 

  

	 	(b)	The Existing Voting Agreement and the Amended and Restated Agreement shall each be terminated and of no further force or effect as of the Effective Time. 

 

	2.	Board of Directors; Grant of Irrevocable Proxy. 

  

	 	(a)	The Shareholders agree to vote all shares of voting capital stock of the Company that they own (“Company Capital Stock”), of record or beneficially, whether
beneficially owned on the date hereof or hereafter, to cause and maintain the election to the Board of Directors of: (a) two persons designated by Leininger (the “Leininger Designees”), and (b) one person designated by Vodafone (or,
if the Company’s Board constitutes more than nine members, two persons) (collectively, the “Vodafone Designees” and together with the Leininger Designees, the “Designees”), and to take all other reasonable
action that may be necessary or proper to effect the foregoing, including without limitation attendance at annual or special meetings of the Company’s shareholders (in person or by proxy), however called, and at any adjournments or
postponements thereof, for purposes of obtaining a quorum and the execution of written consents in lieu of such meetings. 

  

	 	(b)	The Shareholders shall not vote to remove any Leininger Designee unless such removal is requested by Leininger in writing, and shall not vote to remove any Vodafone Designee unless
such removal is requested by Vodafone in writing. 

  

	 	(c)	If any Designee ceases for any reason to serve as a member of the Board during his or her term of office, the Shareholders agree to vote all shares of Company Capital Stock that
they own, of record or beneficially, for the election to the Board of such new Designee recommended by Leininger or Vodafone and to take all other reasonable action that may be necessary or proper to effect the foregoing. 

 

	 	(d)	If Leininger or Vodafone determines to remove any Leininger Designee or Vodafone Designee, respectively, from the Board, then the Shareholders agree to vote all shares of Company
Capital Stock that they own, of record or beneficially, for the removal from the Board of such Designee, and to take all other reasonable action that may be necessary or proper to effect the foregoing. Leininger or Vodafone, as the case may be, will
provide prior written notice to the other Shareholders of any such determination. 

  

	 	(e)	Each of the Leininger Shareholders hereby appoints Vodafone and each of its officers as such Shareholder’s proxy and attorney-in-fact, with full power of

  

 2 

 substitution and resubstitution, to vote and otherwise act (by written consent or otherwise) with respect
to all shares of Company Capital Stock that such Shareholder is entitled to vote at any meeting of shareholders of the Company, however called, or by consent in lieu of any such meeting, on the matters and in the manner specified in Sections 2(a)
through 2(d) above, inclusive, so as to cause the election and continued appointment of the Vodafone Designees to the Board, until the obligations of such Shareholders are terminated pursuant to Section 4(b) below (at which time the proxy granted in
this paragraph (e) shall terminate without further action by any party). In all other matters, such Shareholder’s shares of Company Capital Stock shall be voted by and in the manner determined by such Shareholder. Such Shareholder hereby
represents that it has not heretofore granted any proxy with respect to such Shareholder’s shares of Company Capital Stock that is inconsistent with the proxy granted hereby and hereby revokes any and all such proxies which may previously have
been granted with respect to such shares. Such Shareholder acknowledges that Vodafone is entering into this Agreement in reliance on such Shareholder’s execution and delivery of this Agreement. Such Shareholder affirms that the proxy granted in
this paragraph (e) is coupled with an interest and may not be revoked. 
  

	 	(f)	Vodafone hereby appoints Leininger as Vodafone’s proxy and attorney-in-fact, with full power of substitution and resubstitution, to vote and otherwise act (by written consent
or otherwise) with respect to all shares of Company Capital Stock that Vodafone is entitled to vote at any meeting of shareholders of the Company, however called, or by consent in lieu of any such meeting, on the matters and in the manner specified
in Sections 2(a) through 2(d) above, inclusive, so as to cause the election and continued appointment of the Leininger Designees to the Board, until the obligations of Vodafone are terminated pursuant to Section 4(b) below (at which time the proxy
granted in this paragraph (f) shall terminate without further action by any party). In all other matters, Vodafone’s shares of Company Capital Stock shall be voted by and in the manner determined by Vodafone. Vodafone hereby represents that it
has not heretofore granted any proxy with respect to its shares of Company Capital Stock that is inconsistent with the proxy granted hereby and hereby revokes any and all such proxies which may previously have been granted with respect to such
shares. Vodafone acknowledges that Leininger is entering into this Agreement in reliance on its execution and delivery of this Agreement. Vodafone affirms that the proxy granted in this paragraph (f) is coupled with an interest and may not be
revoked. 

  

	3.	Exchange Act Filings. Each Shareholder shall make all filings as and when required to be made by such Shareholder with the Securities and Exchange Commission pursuant to the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), as a result of the execution and effectiveness of this Agreement, including all filings required to be made by such Shareholder pursuant to Sections 13(d) and 16(a) of the
Exchange Act and the rules and regulations thereunder, including, without limitation, any Schedule 13D or 13G that may be required to be filed by such Shareholder. The Shareholders agree to give prompt notice to each of any event or change of
beneficial ownership which would require amendment to their respective Schedules 13D or 13G. 

  

 3 

	4.	Termination. 

  

	 	(a)	The obligations of the Shareholders under this Agreement with respect to Leininger Designees shall continue in effect until such time as Leininger ceases to beneficially own,
directly or indirectly, at least 10% of the voting power of the outstanding capital stock of the Company or such earlier time, if any, as Leininger ceases to be entitled to nominate any Leininger Designees under its agreement(s) with the Company,
and at such time, such obligations will automatically terminate without further action by any party. Leininger agrees to notify Vodafone and the other Shareholders promptly after such obligations have terminated under this paragraph.

  

	 	(b)	The obligations of the Shareholders under this Agreement with respect to Vodafone Designees shall continue in effect until such time as Vodafone ceases to beneficially own, directly
or indirectly, at least 10% of the voting power of the outstanding capital stock of the Company or such earlier time, if any, as Vodafone ceases to be entitled to nominate any Vodafone Designees under its agreement(s) with the Company, and at such
time, such obligations will automatically terminate without further action by any party. Vodafone agrees to notify Leininger and the other Shareholders promptly after such obligations have terminated under this paragraph. 

 

	 	(c)	For purposes of this Agreement, “beneficial ownership” shall mean beneficial ownership within the meaning of Rule 13d-3 promulgated under the Exchange Act.

  

	5.	Legends. Each party agrees that, so long as its shares of Company Capital Stock are subject to obligations hereunder (with respect to the Vodafone Designees, the Leininger Designees
or both), such shares shall bear a legend substantially in the form set forth below, and each agrees to execute such documents as may be necessary to cause the Company to affix such legends to any certificates representing such shares of Company
Capital Stock, and consents to the entry in the Company’s records of appropriate stop orders or other customary restrictions against transfers in violation of this Agreement. 

  
 “THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES
REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF A VOTING AGREEMENT DATED APRIL 26, 2004. THESE SECURITIES MAY NOT BE SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF OR ENCUMBERED, EXCEPT IN STRICT

 4 

	6.	Transfer of Rights. Any transferee (other than a Third-Party Transferee, as defined below) to whom a Shareholder transfers shares of Company Capital Stock in any manner (whether
voluntarily or by operation of law) shall, as a condition precedent to such transfer, agree in writing to be bound by the obligations imposed under this Agreement on the transferor of such shares of Company Capital Stock, including the affixing of
legends on the certificates representing such shares. Any transfer of shares in violation of this Agreement shall be void. As used in this Agreement:

a member of the Immediate Family of such Shareholder, (B) a trust, family limited partnership or other entity that is directly or indirectly controlled by or for the benefit of such Shareholder, one or more members of the Immediate Family of such

	7.	Specific Performance. In addition to any and all other remedies that may be available at law in the event of any breach of this Agreement, each Shareholder shall be entitled to
specific performance of the agreements and obligations of the Shareholders hereunder and to such other injunctive or other equitable relief as may be granted by a court of competent jurisdiction. 

  

	8.	Amendments and Waivers. This Agreement constitutes the full and complete agreement of the parties with respect to the subject matter hereof. Any term hereof may be amended and the
observance of any term hereof may be waived only with the written consent of Vodafone and of Leininger Shareholders collectively owning a majority of the Company Capital Stock then owned by all Leininger Shareholders. Any amendment or waiver so
effected shall be binding upon all of the Leininger Shareholders (whether or not so consenting) and their respective heirs, personal representatives, successors and assigns. No waivers or exceptions to any term, condition or provision of this
Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision. 

  

	9.	Stock Splits, Stock Dividends, Etc. In the event of any stock split, dividend, combination, recapitalization, reorganization or other similar event involving the Company, any
securities issued on, in exchange for or with respect to the Company Capital Stock held by Shareholders bound by this Agreement shall become subject to the terms and conditions of this Agreement. 

  

 5 

	10.	Severability. Each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be

Agreement. 

  

	11.	Governing Law; Arbitration. This Agreement shall be governed by and construed under the substantive laws of Delaware, exclusive of its conflicts of laws rules. Any dispute,

jurisdiction thereof. Such arbitration shall be conducted by three arbitrators, one chosen by Vodafone, one chosen by Leininger Shareholders holding a majority of the voting power of the Company Capital Stock then owned by all Leininger
Shareholders, and one chosen by the two arbitrators chosen by Vodafone and the foregoing Leininger Shareholders. Any notices to be given involving arbitration may be provided to such person at the address specified in the notice provision in Section
14. 

  

	12.	Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same
instrument. 

  

	13.	Successors and Assigns; Beneficiaries. Except as otherwise expressly provided in this Agreement, the provisions hereof shall inure to the benefit of, and be binding upon, the

delivered to Leininger in accordance with this 

  

 6 

 Section 14 shall constitute effective notice and delivery of the same to each such Shareholder, for all
purposes hereunder. 
  

	15.	Attorney Fees. In the event that any dispute among the parties to this Agreement should result in litigation or arbitration, the prevailing party in such dispute shall be entitled
to recover from the losing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect to this Agreement, including, without limitation, the reasonable fees and expenses of attorneys and accountants,
which shall include, without limitation, all fees, costs and expenses of successful appeals. 

  

	16.	Other.

 Exhibit 4.5 
  
 THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. THEY HAVE BEEN ACQUIRED SOLELY FOR INVESTMENT AND
NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE DISTRIBUTED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN EXEMPTION
FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED AND ANY APPLICABLE STATE SECURITIES LAWS. 
  
 AMENDED AND RESTATED WARRANT 
  
  To Purchase Up To 797 Shares of Common Stock of ATX Group, Inc., a Delaware Corporation (“ATX Group”) 
   
 WHEREAS, ATX Technologies, Inc. (“ATX”) granted to Hi-Tek
INTERNATIONAL, L.L.C. (“Hi-Tek”) that certain Warrant, dated as of July 2, 1998, exercisable by Hi-Tek for purchase up to 2,857 shares of common stock, par value $.01 per share of ATX (“ATX Common Stock”), at a
price of $1.75 per share upon the terms and conditions set forth therein (the “PriorWarrant”), a copy of which is attached hereto as Exhibit A; and 
  
  WHEREAS, (i) ATX has effected a reorganization pursuant to which ATX became a wholly-owned subsidiary of ATX Group as a
result of the merger of a wholly-owned subsidiary of ATX Group with and into ATX (the “ATX Reorganization”), pursuant to which each share of ATX Common Stock outstanding prior to the ATX Reorganization has been converted into the
right to receive in exchange for such share of ATX Common Stock, 797 shares of common stock, par value $.01 per share, of ATX Group (the “ATX Group Common Stock”), and (ii) ATX has consummated (funded and closed) an underwritten
public offering of shares of ATX Group Common Stock pursuant to a registration statement under the Securities Act of 1933, as amended (the “IPO”); and 
   
 WHEREAS, pursuant to the terms of Section 11 of the Prior Warrant and as a result of ATX Reorganization, ATX Group has
assumed the obligations of ATX under the Prior Warrant, which has been cancelled and superceded by this Amended and Restated Warrant (the “Warrant”). 
  

	1.	Number of Shares; Exercise Price. This certifies that Hi-Tek is entitled, upon the terms and subject to the conditions hereinafter set forth, to acquire from ATX
Group, in whole or in part, from time to time, up to 797 fully paid and nonassessable shares (the “Shares”) of ATX Group Common Stock at a purchase price of $6.28 per Share (the “Exercise Price”). The number of
Shares, type of security and Exercise Price are subject to adjustment as provided in Section 11 of this Warrant, and all references to “Common Stock” and “Exercise Price” herein shall be deemed to include any such
adjustment or series of adjustments. 

	2.	Term. The right to purchase Shares under this Warrant shall be fully vested on the grant date above and shall continue until July 2, 2008. 

  

	3.	Exercise of Warrant. The purchase rights represented by this Warrant are exercisable by Hi-Tek, in whole or in part, at any time, or from time to time, by the
surrender of this Warrant and the “Notice of Exercise” attached hereto, all duly completed and executed, on behalf of Hi-Tek, at the principal office of ATX Group in Irving, Texas (or such other office or agency of ATX Group as it
may designate) and upon payment of the Exercise Price for the Shares thereby purchased (by cash, certified or cashier’s check or wire transfer payable to the order of ATX Group). Thereupon, Hi-Tek as the holder of this Warrant, shall be
entitled to receive from ATX Group a stock certificate in proper form representing the number of Shares so purchased, and a new Warrant in substantially identical form and dated as of such exercise for the purchase of that number of Shares equal to
the difference, if any, between the number of Shares subject to this Warrant and the number of Shares as to which this Warrant is so exercised. 

  

	4.	Issuance of Shares. Certificates for Shares purchased hereunder shall be delivered to Hi-Tek promptly after the date on which this Warrant shall have been exercised in
accordance with the terms hereof. ATX Group hereby represents and warrants that all Shares that may be issued upon the exercise of this Warrant will, upon such exercise, be duly and validly authorized and issued, fully paid and nonassessable. ATX
Group agrees that the Shares so issued shall be and shall for all purposes be deemed to have been issued to Hi-Tek as the record owner of such Shares as of the close of business on the date on which this Warrant shall have been exercised or
converted in accordance with the terms hereof. 

  

	5.	No Rights as Stockholders. This Warrant does not entitle Hi-Tek as a holder hereof to any voting rights or other rights as a stockholder of ATX Group prior to the
exercise hereof. 

  

	6.	Charges, Taxes and Expenses. Certificates for Shares issued upon exercise of this Warrant shall be issued in the name of Hi-Tek as the holder of this Warrant. Issuance
of certificates for Shares upon the exercise of this Warrant shall be made without charge to Hi-Tek for any issue or transfer tax or other incidental expense in respect of the issuance of such certificates. 

  

	7.	No Transfer. This Warrant and any rights hereunder are not transferable by Hi-Tek as the holder hereof, in whole or in part. 

  

	8.	Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by ATX Group of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and in the case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it, and upon reimbursement to ATX Group of all reasonable expenses incidental thereto, and upon surrender and cancellation of this
Warrant, if mutilated, ATX Group will make and deliver a new Warrant of substantially the same form and dated as of such cancellation and reissuance, in lieu of this Warrant. 

  

 -2- 

	9.	Reservation of Common Stock. ATX Group will at all times reserve and keep available, solely for issuance, sale and delivery upon the exercise of this Warrant, such
number of shares of ATX Group Common Stock, equal to the number of such Shares purchasable upon the exercise of this Warrant. All such Shares shall be duly authorized and, when issued upon exercise of this Warrant in accordance with the terms
hereof, will be validly issued and fully paid and non-assessable. 

  

	10.	Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall be a
Saturday or a Sunday or shall be a legal holiday of the United States, then such action may be taken or such right may be exercised on the next succeeding day that is not a Saturday or a Sunday or a legal holiday of the United States.

  

	11.	Adjustments of Rights. The Exercise Price per Share and the number and type of Shares purchasable hereunder are subject to adjustment from time to time as follows:

  

	 	a.	Reclassification, Recapitalization, etc. If ATX Group at any time shall, by subdivision, combination or reclassification of securities, recapitalization, or other similar
event affecting the number or character of outstanding shares of Common Stock, or otherwise, change any of the securities as to which purchase rights under this Warrant exist into the same or a different number of securities of any other class or
classes, this Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities that were subject to the purchase rights under this
Warrant immediately prior to such subdivision, combination, reclassification or other change. 

  

	 	b.	Subdivision or Combination of Shares. If ATX Group at any time while this Warrant remains outstanding and unexpired shall split, subdivide or combine the securities as to
which purchase rights under this Warrant exist, the Exercise Price per Share shall be proportionately decreased in the case of a split or subdivision or proportionately increased in the case of a combination. 

  

	 	c.	Common Stock Dividends. If ATX Group at any time while this Warrant is outstanding and unexpired shall pay a dividend with respect to Common Stock payable in shares of Common
Stock, or make any other distribution with respect to Common Stock of shares of Common Stock, then the Exercise Price shall be adjusted from and after the date of determination of the shareholders entitled to receive such dividend or distribution,
to that price determined by multiplying the Exercise Price per Share in effect immediately prior to such date of determination by a fraction (i) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior
to such dividend or distribution, and (ii) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution. This paragraph shall apply only if and to the extent that, at the
time of such event, this Warrant is then exercisable for Common Stock. 

  

 -3- 

	 	d.	Adjustment of Number of Shares. Upon each adjustment in the Exercise Price pursuant to 11(b) or 11(c) hereof, the number of Shares purchasable hereunder shall be adjusted, to
the nearest whole Share, to the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the Exercise Price by a fraction (i) the numerator of which shall be the Exercise Price immediately prior to
such adjustment, and (ii) the denominator of which shall be the Exercise Price immediately after such adjustment. 

  

	 	e.	The preceding sections notwithstanding, this Section 11 shall have no force or effect with respect to the transactions contemplated in connection with the ATX Reorganization
and the IPO, and there shall be no adjustment of the exercise price or the number or type of shares purchasable under the Warrant as a result of the ATX Reorganization and the IPO except as specifically provided in this Agreement.

  

	12.	Notice of Adjustments; Notices. Whenever the Exercise Price or number or type of securities issuable hereunder shall be adjusted pursuant to Section 11 hereof,
ATX Group shall issue and provide to Hi-Tek as the holder of this Warrant a certificate signed by an officer of ATX Group setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such
adjustment was calculated and the Exercise Price and number of Shares purchasable hereunder after giving effect to such adjustment. 

  

	13.	Governing Law. This Warrant shall be binding upon any successors or assigns of ATX Group. This Warrant shall constitute a contract under the laws of Texas and for all
purposes shall be construed in accordance with and governed by the laws of said state, without giving effect to the conflict of laws principles. 

  

	14.	Amendments. This Warrant may be amended and the observance of any term of this Warrant may be waived only with the written consent of both ATX Group and Hi-Tek as the
holder of this Warrant.

 1. The undersigned hereby elects to purchase shares (the “Shares”) of common stock $.01 par value of ATX Group, Inc. pursuant to the terms of
the attached Warrant, and tenders herewith payment of the purchase price and any transfer taxes payable pursuant to the terms of the Warrant, together with an investment Representation Statement in form and substance satisfactory to legal counsel to

 2. The Shares to be received by the undersigned
upon exercise of the Warrant are being acquired for its own account, not as a nominee or agent, and not with a view to resale or distribution of any part thereof, and the undersigned has no present intention of selling, granting any participation

 3. The undersigned understands that the Shares are

THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. THEY HAVE BEEN ACQUIRED SOLELY FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED,
HYPOTHECATED OR OTHERWISE DISTRIBUTED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED AND ANY APPLICABLE STATE SECURITIES LAWS.” 
  
 (b) Any legend required by applicable state law. 

 
 5. Please issue a certificate or certificates representing said Shares in
