                                 STOCK PURCHASE AGREEMENT     


         THIS STOCK PURCHASE AGREEMENT is made this 5th day of October, 1994, by
and between LET'S TALK CELLULAR OF AMERICA, INC., a Florida corporation (the
"Company"), and ALLAN C. SORENSEN, a Florida resident ("Purchaser").

         WHEREAS, the Company desires to sell to the Purchaser, and the 
Purchaser desires to purchase from the Company, shares of the common stock of
the Company, par value $1.00 per share (the "Shares"), on the terms and
conditions set forth herein;

         NOW, THEREFORE, for and in consideration of the premises and agreements
contained herein, the parties hereto agree as follows:

         Section 1. Transfer of the Shares.

         (a)  Upon the terms and subject to the conditions set forth herein, the
    Company shall issue to the Purchaser, 100 Shares, free and clear of all 
    liens, encumbrances and limitations of any kind or nature (collectively,
    "Liens"), 60 of which Shares shall be delivered to the Purchaser at the
    Closing and 40 of which Shares shall be delivered to the Escrow Agent (as
    defined in Section 8.2) at the Closing to be held pursuant to the terms of
    the Escrow Agreement (as defined in Section 8.2).

         (b)  If the Company shall reorganize its capital, reclassify its 
    capital stock, consolidate or merge with another corporation, or sell or
    otherwise consummate any transaction involving the issuance of the capital
    stock of the Company ("Dilutive Event"), the Company shall issue to the
    Purchaser additional Shares, free and clear of all Liens, such that, after
    giving effect to all such transactions and the Purchaser's then current
    holdings of Shares, the Purchaser shall own 10% of the issued and
    outstanding capital stock of the Company. The obligation of the Company to
    issue to the Purchaser additional Shares pursuant hereto shall terminate on
    (the "Termination Date"): (i) the day prior to the consummation of the
    Company's initial public offering which is registered with the Securities
    and Exchange Commission (the "Registered Offering") or, if earlier, (ii) the
    date on which Nick Molina and Brett Beveridge (collectively, the "Principal
    Shareholders") shall


   2



    cease to own in the aggregate at least 75% of the issued and outstanding
    capital stock of the Company as a result of the issuance of capital stock
    pursuant to Dilutive Events (thus, for purposes of determining pursuant to
    this clause (b) whether the Principal Shareholders still own at least
    seventy-five percent (75%) of the issued and outstanding capital stock of
    the Company, they shall be deemed to still own all shares of capital stock
    transferred by the Principal Shareholders and all capital stock issued by
    the Company to family members and affiliates of the Principal 
    Shareholders.) The purpose of this Section 1(b) is to assure that the
    Purchased Shares represent, at all times through and including the
    Termination Date, ten percent (10%) of the issued and outstanding capital
    stock of the Company on a fully-diluted basis. For purposes of this 
    Agreement, the phrase "on a fully-diluted basis" shall mean after giving
    effect to the issuance of securities pursuant to any then outstanding
    preemptive rights, subscriptions, options, warrants, puts, calls,
    rights, exchangeable or convertible securities or other agreements or
    commitments of any character obligating the Company to issue, transfer,
    sell, purchase or redeem any of its securities. Promptly after the
    consummation of each transaction giving rise to such issuance, the Company
    shall deliver certificates representing 60% of all additional Shares
    issued hereunder to the Purchaser and certificates representing the
    remaining 40% of such additional shares to the Escrow Agent, or, if the
    Escrow Agreement shall have terminated pursuant to the terms thereof, all
    such certificates to the Purchaser, in each case bearing such legends as
    the Company shall reasonably require.

         The Shares described in clauses (a) and (b) above are hereinafter 
    referred to as the "Purchased Shares".

         Section 2. Consideration.

         In consideration and payment in full for the Purchased Shares, the 
Purchaser shall pay $250,000 in cash to the Company on the Closing Date.

         Section 3. Option to Repurchase.

         The Company shall have the right, but not the obligation, to purchase 
from the Purchaser, in each case free and clear of all Liens:



                                      -2-
   3



         (a)  one-fourth of all Purchased Shares held in escrow by the Escrow 
    Agent, for an aggregate exercise price of $1.00, if, on or before the first
    anniversary of the Closing Date, the Purchaser has not submitted to the
    Board of Directors of the Company a Proposal for a Nationwide Distribution
    Network. For purposes of this clause (a), "Proposal for a Nationwide
    Distribution Network" shall mean a written proposal prepared by or on behalf
    of the Purchaser setting forth in reasonable detail the comparative
    material features, including, without limitation, geographic scope, time to
    implement, costs, projected benefits, legal requirements and marketing      
    advantages, of three or more methods of distributing the Company's
    products, including franchising and licensing, and containing the
    Purchaser's recommendations and reasons therefor; and

         (b)  three-fourths of all Purchased Shares held in escrow by the Escrow
    Agent, for an aggregate exercise price of $1.00, if, on or before the second
    anniversary of the Closing Date, the Company has not received net proceeds
    in the aggregate amount of $1,000,000 or more from any sale or sales of
    securities of the Company (whether through a public offering, private
    placement or otherwise), or from any institutional or other borrowing (other
    than pursuant to any lines of credit which any of the Principal Shareholders
    have guaranteed), or from any combination thereof.

         The option granted pursuant to clause (a) above shall be exercisable by
delivery of notice to the Purchaser and payment of the exercise price at any
time after the first anniversary of the Closing Date, and the option granted
pursuant to clause (b) above shall be exercisable by delivery of notice and
payment of the exercise price to the Purchaser at any time after the second
anniversary of the Closing Date, Each option shall expire if notice of exercise
and payment are not received by the Purchaser on or before the thirtieth day
after such option first becomes exercisable. Upon exercise or expiration or an
option, as the case may be, the Company and the Purchaser shall give written
instructions to the Escrow Agent to release the Purchased Shares subject to
such option which are then held in escrow, to the Company in the event of an
exercise, or to the Purchaser in the event of expiration.

         The Purchaser represents and warrants to the Company as of the date
hereof and as of the Closing Date as follows:

         5.1  Enforceable Obligation. This Agreement has been duly executed
and delivered by the Purchaser and constitutes a valid and binding obligation of
the Purchaser enforceable against the Purchaser in accordance with its terms.
Each of the Consulting Agreement and the Escrow Agreement shall, when it is
executed and delivered by the Purchaser, be duly executed and delivered by the
Purchaser and shall constitute the valid and binding obligation of the Purchaser
enforceable against the Purchaser in accordance with its terms.

         5.2  No Violation. The execution, delivery and performance by the
Purchaser of this Agreement, the Escrow Agreement and the Consulting Agreement
shall not constitute a violation of, or be in conflict with, or result in a
breach of, or constitute a default under, or contravene any provision of, any

judgment, decree, order or award, by which the Purchaser is bound or to which
any of his assets are subject.

         5.3  Securities Laws. The Purchaser is purchasing the Purchased Shares 
for his own account and for investment and not with a view to, or for sale in
connection with, any distribution of securities.

         Section 6. Covenants.

         6.1  Conduct of the Business. Prior to the Closing, the Company and its
subsidiaries shall carry on their businesses in the ordinary course consistent
with past practice and shall use their best efforts to preserve intact their
present business organization and their relationships with customers.

         6.2  Access to Information. During the period from the date hereof 
to the Closing Date, upon reasonable notice, the Company shall afford to the
Purchaser access, during normal business hours, to the properties, books,

cause his representatives not to, unduly interfere with the business and
employees of the Company and its subsidiaries. The

                                       -6-


   7



Purchaser shall use all non-public information disclosed by the Company or its
representatives solely for the purpose of evaluating the transactions 
contemplated hereby and shall not disclose to any person or entity other than
his representatives or use such information for any other purpose, except as
required by applicable law or legal process, without the prior written consent
of the Company. The Purchaser shall inform his representatives of the
confidential nature of such information and shall obtain the agreement of each
such representative to maintain and use such non-public information in a manner
consistent with the provisions of this Section 6.2. If this Agreement is
terminated, the Purchaser shall, and shall cause his representatives to,
destroy or deliver to the Company all non-public documents, work papers and
other materials containing any non-public information, whether obtained before
or after the date of execution hereof.

         6.3  Restrictions on Transfer. 

         (a)  If the Purchaser shall desire to sell or otherwise dispose of, 
    grant any option with respect to, or create, incur, assume or suffer to
    exist any Lien on the Purchased Shares (collectively, a "Transfer"), then
    in his possession and not held by the Escrow Agent (the "Non-Escrow
    Shares"), he shall first offer to sell such Shares to the Company by
    delivering to the Company notice of the proposed Transfer. Such notice shall
    state the number of Non-Escrow Shares offered and the price and terms upon
    which such Shares are proposed to be Transferred. The Company shall have
    the right to elect upon notice to the Purchaser within 30 days thereafter
    to purchase all, but not less than all, of the Non-Escrow Shares at the
    same price and upon the same terms and conditions as those contained in
    such offer by giving notice to the Purchaser within the 30-day period.
    Notwithstanding the foregoing, if the proposed Transfer is to occur
    subsequent to the Registered Offering, the Purchaser may give Company
    notice of the Transfer telephonically or by fax and the Company's right
    to elect to purchase pursuant this Section 6.3 must be exercised within
    forty-eight (48) hours after notice is given telephonically or by fax by
    the Purchaser. If the Company does not elect to purchase all of the
    Non-Escrow Shares within the aforesaid period or, if, after accepting such
    offer, the Company fails to purchase all such Shares in accordance
    herewith, then the Purchaser shall be free to Transfer all such Shares to
    anyone at not less than the price and on the same terms and conditions
    contained in the

                                       -7-


   8



    offer within 90 days following, as the case may be, (x) the default by the
    Company to make such purchase of such Shares on the closing date, or (y) the
    earlier of either (1) the expiration of the period within which the Company
    may elect to purchase such Shares or (2) the giving of notice by the
    Company to the Purchaser that it does not elect to purchase all of
    Non-Escrow Shares. Promptly after the execution of any contract for the
    Transfer of such Shares, the Purchaser shall deliver to the Company a true
    and complete copy of such contract and all amendments thereto, and such
    other information relating to the contract and the proposed purchaser as
    the Company may request. Upon the consummation of the Transfer of such
    Shares, the Purchaser shall notify the Company thereof and shall certify
    the price and terms and conditions upon which such Transfer was made. Any
    attempted Transfer of Purchased Shares by the Purchaser otherwise than in
    full compliance herewith shall be null and void.

         (b)  In the event that either or both of the Principal Shareholders 
    propose to engage in one or more Transfers prior to the consummation of the
    Registered Offering which would result in the Principal Shareholders owning
    in the aggregate less than 51% of the voting capital stock of the Company,
    the Transferors shall give written notice to the Purchaser setting forth
    the material terms of the proposed Transfer. If the Purchaser so elects by
    delivery of written notice to the Transferors, the Principal Shareholders
    shall not Transfer their Shares unless the Transferee agrees to purchase
    such number of Non-Escrow Shares as is specified in the notice, at the same
    pries per share and upon the same terms and conditions, as such Transferee
    proposes to purchase the Shares of the Transferors.

         6.4  Incidental Registration. 

         (a)  If, on any one or more occasions, the Company proposes to register
    its Shares under the Securities Act of 1933, as amended (the "Securities
    Act"), by registration on Forms S-1, S-2, S-3, SB-1 or SB-2, or any
    successor, or similar form(s), whether or not for sale for its own account,
    it will each such time give prompt written notice to the Purchaser of its
    intention to do so. The Purchaser shall be entitled pursuant to the
    provisions of this Section 6.4 to request the registration of up to 30% of
    his Non-Escrow Shares. Upon the written request of the

                                       -8-

   9



    Purchaser made as promptly as practicable and in any event within 20 days
    after the receipt of any such notice (which request shall specify the
    Purchased Shares intended to be included by the Purchaser in such
    registration), the Company will use its best efforts to effect the
    registration under the Securities Act of a number of Purchased Shares not to
    exceed 30% of the Non-Escrow Shares which the Company has been so requested
    to register; provided, however, that if, at any time after giving written
    notice of its intention to register any Non-Escrow Shares and prior to the
    effective date of the registration statement filed in connection with such
    registration, the Company shall determine for any reason to delay or not to
    complete the registration of the Company's Shares in which Purchased Shares
    were to be included pursuant to this Section 6.4(a). The Company may, at its
    election, give written notice of such determination to the Purchaser and (i)
    in the case of a determination not to register, shall be relieved of its
    obligation to register any Non-Escrow Shares in connection with such
    registration, without prejudice, however, to the rights of the Purchaser
    hereunder, and (ii) in the case of a determination to delay registering,
    shall be permitted to delay registering any Non-Escrow Shares for the same
    period as the delay in registering such other securities; and provided
    further that, subsequent to the Registered Offering, the Company shall not
    be required to register pursuant to this Section 6.4(a) Purchased Shares
    that are then eligible for resale pursuant to Rule 144 under the Securities
    Act. For purposes of this Section 6.4, the term "Non-Escrow Shares" will be
    deemed to include all shares issued on or in respect of the Purchased Shares
    as a result of a stock split, stock dividend or otherwise. The rights of the
    Purchaser under this Section 6.4 shall be pari passu with, but not superior
    to, any other registration rights outstanding in regard to the capital stock
    of the Company. Any underwriters' discounts and commissions with respect to
    the Purchased Shares shall be allocated to and paid by the Purchaser based
    on the number of Non-Escrow Shares registered. The Purchaser shall pay for
    all of the fees and expenses of counsel retained by him.

         (b)  If the managing underwriter of any underwritten offering shall 
    inform the Company by letter of its belief that the number of Shares
    requested to be included in such registration would materially adversely
    affect such offering, then the Company will include in such registration, to
    the

                                       -9-


   10



    extent of the number which the Company is so advised can be sold in (or
    during the time of) such offering, first, all Shares proposed by the
    Company to be sold for its own account and second, such Shares requested to
    be included in such registration pro rata among the requesting holders
    according to the total number of Shares requested by such holders.

         (c)  If and whenever the Company is required to use its best efforts to
    effect the registration of any Shares under the Securities Act as provided
    in Section 6.4(a), the Company will as soon as practicable:

              (i)   prepare and (within 60 days after the end of the Company's 
         fiscal quarter within which requests for registration may be given to
         the Company or 90 days in the case of the Company's fourth fiscal
         quarter) file with the Securities and Exchange Commission the requisite
         registration statement to effect such registration and thereafter use
         its best efforts to cause such registration statement to become
         effective;

              (ii)  prepare and file with the Securities and Exchange 
         Commission such amendments and supplements to such registration 
         statement and the prospectus used in connection therewith as may be 
         necessary to keep such registration statement effective and to comply 
         with the provisions of the Securities Act with respect to the 
         disposition of all Shares covered by such registration statement until 
         the earlier of such time as all of such Shares shall have been 
         disposed and 45 days after the effective date of the registration 
         statement;

              (iii) furnish to the Purchaser such number of conformed copies of 
         such registration statement and of each such amendment and supplement
         thereto (in each case including all exhibits), such number of copies of
         the prospectus contained in such registration statement (including each
         preliminary prospectus and any summary prospectus) and any other
         prospectus filed under Rule 424 under the Securities Act, in conformity
         with the requirements of the Securities Act, as the Purchaser may
         reasonably request;


                                      -10-
   11


              (iv)  use its best efforts (x) to register or qualify all of the 
         Shares covered by such registration statement under such other
         securities or blue sky laws of the State of Florida and such other
         States of the United States of America where an exemption is not
         available and as a majority of the sellers of Shares covered by such
         registration statement shall reasonably request, (y) to keep such
         registration or qualification in effect for so long as such
         registration statement remains in effect, and (z) to take any other
         action which may be reasonably necessary or advisable to enable such
         sellers to consummate the disposition in such jurisdictions of the
         securities to be sold by such sellers, except that the Company shall
         not for any such purpose be required to qualify generally to do
         business as a foreign corporation in any jurisdiction wherein it would
         not but for the requirements of this subclause (iv) be obligated to be
         so qualified, to consent to general service of process in any such
         jurisdiction or to subject itself to taxation in any such jurisdiction;
         and

              (v)   use its best efforts to cause all Shares covered by such 
         registration statement to be registered with or approved by such other
         Federal or state governmental agencies or authorities as may be
         necessary in the opinion of counsel to the Company and counsel to the
         sellers of Shares to enable the sellers thereof to consummate the
         disposition of such Shares.

         The Company may require the Purchaser to furnish to the Company such 
information regarding the Purchaser and the distribution of his Purchased Shares
as the Company may from time to time reasonably request in writing.

       NOW THEREFORE, for good and valuable consideration, the receipt, adequacy
and sufficiency whereof are hereby acknowledged, the parties hereto agree as
follows:

                                    AGREEMENT

1.     The above recitals are true and correct and are incorporated herein by
       this reference. All capitalized terms used but not otherwise defined
       herein shall have the respective meanings provided for them in the
       Agreement.

2.     The following sections of the Agreement are hereby amended to read as
       follows:

       a)     Section 6.3(b) of the Agreement is amended by inserting as the
              last sentence of that section the following:

              Immediately prior to the consummation of a Registered Offering by
              the Company, the right of the Consultant to cause the Company to
              repurchase his shares under this Section 6.3(b) shall

              Consultant hereby agrees and acknowledges that his shares shall be
              treated pro rata with the shares of the other Holders of
              Registrable Securities.


   23

                                                                           P. 3

              rights he may have to cause the Company to repurchase his shares
              if the Company commits an "EBIT Default" (as such term is defined
              in that certain Shareholders Agreement, dated as of the date
              hereof, by and among the Company, the Consultant, HIG Fund V.
              Inc., ("HIG"), Nick Molina, and Brett Beveridge and Anne Gozlan)
              to the redemption rights of HIG under (I) the Redemption
              Agreement, dated as of the date hereof, by and between HIG and the
              Company and (II) the Description of Series A Preferred Stock
              attached as Exhibit A to the Purchase Agreement. The Consultant
              agrees that he will not require or receive payment for his shares
              upon the occurrence of an EBIT Deficit until HIG has received all
              payment for the number of shares that it requested the Company to
              repurchase following the occurrence of such an event.

       d.     The Consultant hereby confirms that (I) he currently owns and is
              in possession of 100 shares of the Company's Common Stock, par
              value $1.00 per share, which is evidenced by a Certificate issued
              in the name of Allan C. Sorensen (the "Certificate") and (II) upon
              the effectiveness of the 650-for-1 forward stock split, he shall
              return the Certificate to the Company in exchange for a
              certificate evidencing 65,000 shares of the Company's Common
              Stock, par value $.001 per share.

3.     Except as modified by this Amendment, the parties hereto acknowledge that
       the Agreement remains unmodified and in full force and effect.

       IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of
the date and year first witness above.
