          clear of any and all liens,  security interests or encumbrances of any

          knowledge there is no document,  consent,  agreement,  waiver or other

     5. a. (1) As  consideration  for the  assignment of the Claim,  Issuer,  on
behalf of Assignee, hereby agrees to irrevocably transfer to Assignor, as of the
date  hereof,  four  million  (4,000,000)  shares of common stock of Issuer (the
"Initial Share Holding"),  evidenced by a stock  certificate  (with  appropriate
restrictions  and  restrictive  legends  affixed  thereto)  issued by Issuer and
delivered to Assignor by Issuer's duly appointed stock transfer agent, not later
than ten (10) business days from the date hereof.  Issuer and Assignee represent
and warrant that the Initial Share  Holding and any shares issued  thereafter to
Assignor  shall  be  validly  issued,  fully  paid  and  nonassessable.  On  the
eighteenth  month  anniversary  of the date  hereof  (the  "Subsequent  Transfer
Date"), Issuer, on behalf of Assignee, will transfer to Assignor such additional
number  of  shares  of  common  stock  of  Assignee   (the   "Subsequent   Share
Distribution")  necessary to make the  aggregate  fair market value of shares in
the Initial Share Holding equal four million dollars  ($4,000,000)  (the "Target
Share  Value"),  based on the  weighted  average  formula set forth  herein.  In
determining the number of shares in the Subsequent Share  Distribution,  if any,
on the  Subsequent  Transfer Date Issuer shall average the fifteen (15) highest,
daily,  ending  values of the common  stock for the trading  period  between the
Effective Date (as defined below) and the Subsequent Transfer Date to obtain the
"Weighted  Average  Value." In the event the Weighted  Average Value (A) is less
than $ 1.00 per share,  regardless of the value of the shares of common stock on
the Subsequent  Transfer Date, the Subsequent  Share  Distribution  (B) shall be
computed as follows:

         B = $4.000.000 - (4.000.000 shares x A)

         A

               (2) If the  Weighted  Average  Value is less than $.50 per share.
          Issuer shall use the value of $.50 for the Weighted  Average  Value in
          determining the number of shares in the Subsequent Share Distribution.

               (3) If the  Weighted  Average  Value  exceeds  $ 1.00 per  share.
          Issuer  shall not be  required to transfer  any  additional  shares to
          Assignor,  regardless of the fair market value of the shares of common
          stock on the Subsequent Transfer Date.

               (4) If  Assignor  sells a portion of the Initial  Share  Holdings
          prior to the Subsequent Transfer Date, the Target Share Value shall be
          reduced by the same  percentage  as such sold  shares  comprise of the
          Initial Share  Holdings.  By way of example  only,  if Assignor  sells
          1,000,000  shares,  or twenty-five  percent (25%) of the Initial Share
          Holdings  prior  to  the  Subsequent   Transfer  Date,  then,  on  the
          Subsequent Transfer Date, the Target Share Value shall also be reduced
          by 25% and Issuer shall transfer to Assignor that number of additional
          shares  of  common  stock  of  Issuer  that is  necessary  to give the
          aggregate  number  shares of then held by Assignor a fair market value
          of  $3,000,000.  In such an event,  the  formula for  determining  the
          Subsequent  Share  Distribution  (B), if any,  using the same Weighted
          Average  Value (A) discussed  above and  regardless of the fair market
          value of the shares on the Subsequent Transfer Date, shall be:

                                       4
<PAGE>

         B = $3.000.000 - (3.000.000 shares x A)

         A

               b. Issuer shall prepare and file a registration statement on Form
          S-1 (or such other form as Assignee  is  eligible to use)  registering
          the resale of all of the shares in the  Initial  Share  Holdings  from
          time to time pursuant to Rule 415 under the Securities Act of 1933 (as
          amended,  the  "Securities  Act") in a timely  manner  such  that such
          registration  statement shall become  effective in accordance with the
          terms  hereof.  Following the filing of such  registration  statement.
          Issuer shall use its best efforts to cause such registration statement
          to become  effective no later than the latter of(i) one hundred eighty
          (180)  days  from  the  date  hereof,  or (ii)  November  1,2000  (the
          "Effective  Date").  In addition,  within ten (10) business days after
          the  Effective  Date,  Issuer  shall  issue,  and shall cause its duly
          appointed stock transfer agent to deliver to Assignor, in exchange for
          any existing  certificates,  a stock certificate for the Initial Share
          Holding  with  all  transfer   restrictions  and  restrictive  legends
          removed. Issuer shall thereafter take all actions necessary, including
          the filing of amendments thereto or the filing of a Form 8-K to report
          material events for  incorporation by reference  therein,  to maintain
          effectiveness of such registration statement so long as any shares are
          held by Assignor.  Such registration  statement shall list Assignor as
          "selling  shareholder"  therein and shall be amended as necessary from
          time-to-time  to reflect  transfers of the shares in the Initial Share
          Holdings (or such other shares  subsequently  transferred  to Assignor
          pursuant to this Agreement) by Assignor.

               c. The  registration  requirements  set forth in  paragraph  5(b)
          hereof  shall also apply to the  shares,  if any,  issued by Issuer as
          part of the Subsequent Share  Distribution,  except that the Effective
          Date for such shares shall be one-hundred  eighty (180) days after the
          Subsequent Transfer Date.

               d. In the event Issuer,  at any time, (1) fails to issue or cause
          to be delivered stock  certificates in accordance with paragraph 5 (a)
          hereof, (2) fails to issue or cause to be delivered stock certificates
          in accordance  with paragraph  5(b) hereof,  or (3) violates any other
          provision of this paragraph 5. Issuer shall be deemed to be in default
          of this Agreement.  Upon such default, that certain General Continuing
          Guaranty  dated  as of June 5,  1998,  and  that  certain  Guarantor's
          Security  Agreement  dated as of June 5, 1998,  and that certain First
          Amendment and Reaffirmation of General Continuing Guaranty dated as of
          April 14,  1999,  and that  certain  First  Amendment  to  Guarantor's
          Security  Agreement  dated as of April  14,  1999  (collectively,  the
          "Guaranty Documents"),  all in favor of Assignor,  shall be reinstated
          in their entirety,  with all benefits and obligations  thereof vesting
          in Assignor.

     Notwithstanding  the  foregoing,  in the event  Issuer  cures  any  default
hereunder within three (3) business days from the date of such default. Issuer's
obligations  under the Guaranty  Documents  shall be  terminated,  so long as no
other defaults have occurred and are continuing.

          e. As to the  registration of the shares in the Initial Share Holdings
     and the registration of the shares in the Subsequent Share Distribution, if
     any,  pursuant to paragraph 5(b) and (c). Issuer shall pay all costs,  fees
     and expenses  incident to the  performance  and  compliance  by Issuer with
     paragraph 5(b) and (c). including, without limitation, (1) all registration
     and filing fees; (2) all printing expenses;  (3) all fees and disbursements
     of counsel and independent  public accountants for Issuer; (4) all blue sky
     fees and expenses  (including  fees and  expenses of counsel in  connection
     with blue sky surveys);  (5) all transfer taxes;  (6) the entire expense of
     any  audits  incident  to  such  registration  required  by the  rules  and
     regulations  of the  Securities  and Exchange  Commission;  (7) the cost of
     distributing  prospectuses  in  preliminary  and final  form as well as any
     supplements  thereto;  and (8) the fees and expenses of one counsel for the
     Assignor  in  connection  with the  shares  being  registered  pursuant  to
     paragraph 5(b) and (c) hereof.  Assignor shall bear its proportionate  cost
     of all  underwriting  fees  and  commissions,  if  any,  relating  to  such
     registration,  such  proportionate  amount to be equal to a  fraction,  the
     numerator of which is the amount of shares being registered by Assignor and
     the denominator of which is the aggregate number of shares being registered
     by any and all other  holders  of  Issuer's  shares  participating  in such
     registration.

          in such registration  statement,  any prospectus contained therein, or
          any amendment or supplement thereto, or arise out of or are based upon
          the omission or the alleged  omission to state therein a material fact
          required  to be stated  therein or  necessary  to make the  statements
          therein,  in light of the  circumstances  in which they were made, not
          misleading,  in each case to the extent, but only to the extent,  that
          such  untrue  statement  or alleged  untrue  statement  or omission or
          alleged omission was so made in reliance upon and in strict conformity
          with written information furnished by Assignor specifically for use in
          the preparation thereof. Notwithstanding any provision to the contrary
          contained herein, the aggregate liability of Assignor pursuant to this
          paragraph  5(f)(2)  shall be limited  to an amount  equal to the gross
          proceeds  received by Assignor from the offering of shares  registered
          pursuant to this paragraph 5.

                                       6

               (3) Promptly after receipt by a party indemnified pursuant to the
          provisions of subparagraph (1) or (2) of this paragraph 5(f) of notice
          of the  commencement of any action involving the subject matter of the
          foregoing  indemnity  provisions,  such  indemnified  party will, if a
          claim therefor is to be made against the indemnifying party in writing
          pursuant  to the  provisions  of  subparagraph  (Dor (2).  notify  the
          indemnifying party of the commencement thereof; but the omission so to
          notify the  indemnifying  party will not relieve it from any liability
          which it may have to an  indemnified  party  otherwise than under this
          paragraph  5  and  shall  not  relieve  the  indemnifying  party  from
          liability  under this  paragraph 5. In case any such action is brought
          against any indemnified  party, and it notifies the indemnifying party
          of the commencement  thereof,  the indemnifying party will be entitled
          to  participate  therein and, to the extent that it may wish,  jointly
          with any other indemnifying parties similarly notified,  to assume the
          defense thereof,  with counsel satisfactory to such indemnified party;
          provided,  however,  that if the defendants in any such action include
          both  the  indemnified  party  and  the  indemnifying  party  and  the
          indemnified  party shall have  reasonably  concluded that there may be
          legal defenses available to it and/or other indemnified  parties which
          are  different   from  or   additional  to  those   available  to  the
          indemnifying  party,  the indemnified  party or parties shall have the
          right to select separate counsel (in which case the indemnifying party
          shall not have the  right to  direct  the  defense  of such  action on
          behalf  of the  indemnified  party or  parties).  Upon  the  permitted
          assumption  by the  indemnifying  party of the defense of such action,
          and approval by the indemnified party of counsel,  which approval will
          not be  unreasonably  withheld,  the  indemnifying  party shall not be
          liable to such indemnified  party under  subparagraph ( I ) or (2) for
          any legal or other expenses  subsequently incurred by such indemnified
          party in connection  with the defense  thereof (other than  reasonable
          costs of  investigation)  unless (A) the indemnified  party shall have
          employed  separate  counsel in connection  with the assertion of legal
          defenses in accordance with the proviso to the  immediately  preceding
          sentence,  (B) the indemnifying  party shall not have employed counsel
          satisfactory  to the  indemnified  party to represent the  indemnified
          party within a reasonable  time,  (C) the  indemnifying  party and its
          counsel do not  actively  and  vigorously  pursue the  defense of such
          action, or (D) the indemnifying party has authorized the employment of
          counsel for the indemnified  party at the expense of the  indemnifying
          party. No indemnifying  party shall be liable to an indemnified  party
          for any  settlement  of any action or claim without the consent of the
          indemnifying party and no indemnifying party may unreasonably withhold
          its consent to any such settlement. No indemnifying party will consent
          to entry of any judgment or enter into any  settlement  which does not
          include as an unconditional term thereof the giving by the claimant or
          plaintiff to such  indemnified  party of a release from all  liability
          with respect to such claim or litigation.

                                       7

               (4) If the  indemnification  provided for in subparagraph  (1) or
          (2)  of  this   paragraph  5(f)  is  held  by  a  court  of  competent
          jurisdiction  to be  unavailable  to a party  to be  indemnified  with
          respect to any claims, actions, demands, losses, damages, liabilities,
          costs or expenses referred to therein,  then each  indemnifying  party
          under any such  subsection,  in lieu of indemnifying  such indemnified
          party  thereunder,  hereby  agrees to contribute to the amount paid or
          payable by such indemnified party as a result of such claims, actions,
          demands,  losses,  damages,  liabilities,  costs or  expenses  in such
          proportion as is appropriate to reflect the relative benefits received
          by such  indemnifying  party on the one hand and the indemnified party
          on the other from the related  offering.  If, however,  the allocation
          provided by the  immediately  preceding  sentence is not  permitted by
          applicable law, then each indemnifying  party shall contribute to such
          amount  payable by such  indemnified  person in such  proportion as is
          appropriate  to reflect not only such  relative  benefits but also the
          relative  fault of the  indemnifying  party on the one hand and of the
          indemnified  party on the other in connection  with the  statements or
          omissions  which resulted in such claims,  actions,  demands,  losses,
          damages, liabilities, costs or expenses, as well as any other relevant
          equitable  considerations.   The  relative  benefits  received  by  an
          indemnifying  party on the one hand  and an  indemnified  party on the
          other  shall be deemed to be in the same  proportion  as the total net
          proceeds from the offering  (before  deducting  expenses)  received by
          each party bear to the total net proceeds  from the offering  received
          by each other party and,  with  respect to an  underwriter,  the total
          underwriting  discounts and commissions  received by such underwriter,
          and in each case as set  forth in the  table on the cover  page of the
          related  prospectus.  The relative fault of the indemnifying party and
          of the  indemnified  party shall be  determined by reference to, among
          other  things,  whether the untrue or alleged  untrue  statement  of a
          material fact or the omission or alleged  omission to state a material
          fact relates to information  supplied by the indemnifying  party or by
          the indemnified  party and the parties'  relative  intent,  knowledge,
          access to  information  and  opportunity  to correct  or prevent  such
          statement or omission.

               (5) No person guilty of fraudulent  misrepresentation (within the
          meaning of Section I l(f) of the Securities  Act) shall be entitled to
          contribution  hereunder  from any  person  who was not  guilty of such
          fraudulent misrepresentation.

               (6) In addition  to its other  obligations  under this  paragraph
          5(f).  Issuer  further  agrees to  reimburse  promptly  Assignor  (and
          Assignor's controlling persons, officers,  directors, and underwriters
          (and controlling persons of such underwriters)) on a monthly basis for
          all  reasonable  legal  fees,  expenses  and other  fees and  expenses
          incurred by Assignor in connection with investigating or defending any
          claim, action, investigation,  inquiry or other proceeding arising out
          of or based upon any statement or omission,  or any alleged  statement
          or admission,  described in  subparagraph  (1) of this paragraph 5(f).
          notwithstanding the possibility that such payments might later be held
          to be improper.  To the extent that any payment is ultimately  held to
          be improper,  each person receiving such payment shall promptly refund
          such payment.

                                       8
<PAGE>
               (7) In addition  to its other  obligations  under this  paragraph
          5(f).  Assignor  further  agrees to  reimburse  promptly  Issuer  (and
          Issuer's  controlling  persons,  officers,  directors and underwriters
          (and controlling persons of such underwriters)) on a monthly basis for
          all  reasonable  legal  fees,  expenses  and other  fees and  expenses
          incurred by Issuer in connection with  investigating  or defending any
          claim, action, investigation,  inquiry or other proceeding arising out
          of or based upon any statement or omission,  or any alleged  statement
          or admission,  described in  subparagraph  (2) of this paragraph 5(f).
          notwithstanding the possibility that such payments might later be held
          to be improper.  To the extent that any payment is ultimately  held to
          be improper,  each person receiving such payment shall promptly refund
          such payment.

     6. Assignee  agrees to indemnify  Assignor and hold Assignor  harmless from
any liability, cost, penalties or expenses (including reasonable attorneys' fees
and disbursements) for any amounts owed by Ameritel to any taxing authority,  to
extent such amounts are chargeable to Ameritel's secured lender.

     7. Assignor  acknowledges that Assignee currently may possess and hereafter
may come into  possession  of certain  information  that may be  material to its
decision  to  sell,   hold  or  purchase  the  Claim  (the  "Assignee   Excluded
Information");  Assignor,  independently  and without reliance upon Assignee and
based on such documents and information as Assignor has deemed appropriate,  has
made its own credit  analysis and decision to enter into this  Agreement  and to
sell the Claim; and Assignor hereby waives and releases any claims that Assignor
might now or hereafter have against  Assignee or any of its affiliates and their
respective directors,  officers, employees, agents,  representatives,  partners,
controlling  persons,  successors  and assigns,  whether  pursuant to applicable
bankruptcy law, securities law or otherwise,  with respect to the non-disclosure
of Assignee Excluded  Information Assignor further represents that it is not and
never has been an "insider" of Ameritel.

     8. Assignee  acknowledges that Assignor currently may possess and hereafter
may come into  possession  of certain  information  that may be  material to its
decision  to  sell,   hold  or  purchase  the  Claim  (the  "Assignor   Excluded
Information");  Assignee,  independently  and without reliance upon Assignor and
based on such documents and information as Assignee has deemed appropriate,  has
made its own credit  analysis and decision to enter into this  Agreement  and to
purchase  the Claim;  and  Assignee  hereby  waives and releases any claims that
Assignee might now or hereafter  have against  Assignor or any of its affiliates
and their respective directors,  officers,  employees, agents,  representatives,
partners,  controlling  persons,  successors  and assigns,  whether  pursuant to
applicable  bankruptcy  law,  securities  law or otherwise,  with respect to the
non-disclosure of Assignor Excluded Information.

     9.  Notwithstandinganything  otherwise  contained  herein,  the undersigned
parties hereby agree that Assignor shall retain,  and Assignee shall not take an
assignment  of, any and all claims that  Assignor  may have  against any and all
public  accountants  or  other  independent   financial  advisors  of  Ameritel,
including without  limitation claims for accountant  liability and other related
or similar claims related to work performed prior to the date hereof.

     10.  In the  event  the  Claim  is  ultimately  allowed  in the  Bankruptcy
Proceedings in an amount  greater than the amount set forth herein.  Assignee is
hereby  deemed to have  purchased,  and Assignor is hereby  deemed to have sold,
such additional amount for the same consideration paid herein.

     11. In the event all or any part of the Claim is disallowed,  subordinated,
objected  to or  otherwise  impaired,  in whole or in  part,  in the  Bankruptcy
Proceedings for any reason whatsoever, Assignor agrees to cooperate or assist in
the defense of such claim and that  Assignee  shall have the right to defend the
allowability  of the Claim on Assignor's  behalf;  provided,  however,  that all
costs and expenses  incurred in such defense  shall be paid by Assignee,  unless
such claim is related to a misrepresentation made by Assignor hereunder.

     12.  Assignor  agrees that in the event Assignor shall receive any payments
or  distributions  and any  notices  with  respect  to the Claim  after the date
hereof,  Assignor agrees to accept the same as Assignee's agent and to hold same
in trust on behalf of and for the benefit of Assignee,  and shall promptly remit
the same  forthwith  to  Assignee  in the same  form  received,  within  two (2)
business  days in the case of cash and within five (5) business days in the case
of securities,  which are in good and deliverable  form, with the endorsement of
Assignor when necessary or appropriate.

     13. Assignor hereby  irrevocably  appoints  Assignee as its true and lawful
attorney-in-fact  and authorizes  Assignee to act in Assignor's  name, place and
stead,  to file a Proof of Claim or to demand,  sue for,  compromise and recover
all such sums of money  which now are, or may  hereafter  become due and payable
for, or on account of the Claim herein  assigned.  Assignor grants unto Assignee
full authority to take all actions necessary to enforce the Claim and Assignor's
rights  thereunder  pursuant to this Agreement.  Assignor agrees that the powers
granted by this paragraph 13 are  discretionary in nature and exercisable at the
sole  option  of  Assignee.  Assignor  shall  have no  obligation  to  take  any
affirmative  action to prove or defend  the  Claim's  validity  or amount in the
Bankruptcy Proceedings.  Assignor agrees to execute, acknowledge and deliver all
such further certificates, instruments and other documents, and to take all such
further action as may be necessary or  appropriate  to effect  assignment of the
Claim and all  interests  therein  to  Assignee,  to  cooperate  with and assist
Assignee in enforcing the Claim and to otherwise  effectuate  the intent of this
Agreement  Assignor agrees that Assignee may sell,  transfer or assign the Claim
together  with  all  right,  title  and  interest  of  Assignee  in and to  this
Agreement.

     14. Assignor shall be solely  responsible for professional fees and similar
costs or expenses  payable by or reimbursable  to Assignor  relating to the Loan
Documents or the Bankruptcy  Proceedings that are incurred for services rendered
by  professionals  retained by Assignor on or before the date  hereof.  Assignee
shall be  responsible  for all  professional  fees and similar costs or expenses
payable by or  reimbursable  to Assignee  relating to the Loan  Documents or the
Bankruptcy  Proceedings that are incurred for services rendered by professionals
retained by Assignee after the date hereof.  Each party shall bear its own fees,
costs and expenses  related to the transaction  hereunder.  Notwithstanding  the
foregoing,  Assignor and Assignee shall also be responsible for all professional
fees  and  similar  costs  or  expenses  payable  as part of the  Carve-Out,  in
accordance with the terms hereof.

attorneys' fees and  disbursements)  incurred by Assignee and owed to any Person
other than Ameritel,  Issuer, any of their affiliates,  subsidiaries,  officers,
directors or other related  personnel,  or any of their respective  successor or
assigns,  resulting  from or arising out of (i) the breach of any of  Assignor's

reserves  the  right  to  initiate  its  own   defense,   prosecute   applicable
counterclaims  or  cross-claims,  appoint  counsel,  negotiate a  settlement  or
compromise  or  otherwise  defend  against  such claim or cause of action in any
manner that  Assignor,  in the  exercise  of its own  business  judgment,  deems
appropriate, and will not be bound by any settlement or other resolution of such
claim or cause of action entered into or ordered upon Assignee or Issuer without
Assignor's prior written consent.

     17.  Assignee  agrees  to  indemnify  Assignor  against  and hold  Assignor
harmless from any Expense incurred by Assignor  resulting from or arising out of
(i) the breach of any of Assignee's representations,  warranties,  agreements or
covenants  contained herein, (ii) the Assumed  Obligations,  or (iii) Assignee's
gross negligence or wilful misconduct.

     18. All  representationsand  warranties  contained herein shall survive the

The  Released  Assignor  Parties  acknowledge  and agree  that this  release  is
