                                    A.      any breach of the representations
and warranties made by Purchaser in this Agreement or any certificate delivered

perform any covenant or agreement contained in this Agreement.

                             (iii)  Indemnity Procedure for Third Party Claims.

                                    A.      Promptly after receipt by a party
seeking  indemnification  hereunder  (an  "Indemnified  Party) of notice (a
"Third Party Claim Notice") of any claim,  or of the  commencement  by any third
party of any action,  suit or proceeding,  which might result in the other party
hereto (the  "Indemnifying  Party") becoming  obligated to indemnify or make any
other payment to the  Indemnified  Party under this  Agreement,  the Indemnified
Party  shall  notify  the  Indemnifying   Party  forthwith  in  writing  of  the
commencement thereof or of the claim. The failure of the Indemnified Party to so
notify the Indemnifying  Party shall not relieve the Indemnifying Party from any
liability  which it may have on account of this  indemnification  or  otherwise,
except and only to the extent that the Indemnifying Party is prejudiced thereby.

                                    B.      The Indemnifying Party shall have
the right,  within thirty (30) days after being so notified,  to assume the
defense  of  such  claim,  litigation  or  proceeding  with  counsel  reasonably
satisfactory  to the  Indemnified  Party in good  faith and at the  Indemnifying
Party's own expense.






                                    C.      Unless and until the Indemnifying
Party shall assume such defense  pursuant to the  foregoing  sentence,  the
Indemnified  Party  shall have the right to conduct  and  control the defense of
such claim,  litigation or proceeding (including the settlement thereof) without
the Indemnifying Party's consent and, without limiting any other indemnification
obligation,  shall be entitled  to payment  from the  Indemnifying  Party of all
reasonable costs of such defense (including attorneys' fees and expenses).

                                    D.      In any such claim, litigation or
proceeding  the  defense  of which the  Indemnifying  Party  shall  have so
assumed,  the Indemnified Party shall have the right to participate  therein and
retain its or his own counsel at its or his own expense, unless

                                            (a)    the Indemnifying Party and
the  Indemnified  Party shall have mutually  agreed to the retention of the
same counsel, or

                                            (b)    the named parties to any such
litigation or proceeding  (including  impleaded  parties)  include both the
Indemnifying Party and the Indemnified Party, and representation of such parties
by the same counsel would be inappropriate due to actual or potential  differing
interests  between them in which case, such separate  counsel may be retained by
the Indemnified Party at the expense of the Indemnifying Party.

                                    E.      The Indemnifying Party may elect to
settle any claim,  action or  proceeding  defended by it or him without the
written  consent of the  Indemnified  Party  provided  that such  settlement  is
limited  to  payment  of  monetary  damages  which  are  payable  in full by the
Indemnifying  Party and the Indemnified Party is fully discharged at the time of
the  settlement  from  any  liability  with  respect  to the  claim,  action  or
proceeding. The Indemnifying Party may not enter into any settlement that is not
limited to payment of monetary  damages  without the  Indemnified  Party's prior
written consent which will not be unreasonably withheld.

                                    F.      Seller and Purchaser covenant to use
all  reasonable  efforts to cooperate  fully with respect to the defense of
any claim, action or proceeding covered by this section.

               9.  Offset.  In the event  that  seller  is  liable to  Purchases
pursuant  to  Section  8 or  Purchaser  receives  a Third  Party  Claim  Notice,
Purchaser  may (but shall not be  obligated  to) offset all or a portion of such
liability or potential liability against any other payment owing to Seller under
Sections  2(b)  and (c) of  this  Agreement  and  section  3D of the  Employment
Agreement between Purchaser and Seller.






               10.  Purchaser's  Covenants.  After the Closing,  Purchaser shall
lend to TeleSite the sum of $750,000 in accordance  with a future  business plan
reasonably satisfactory to Purchaser.

               11.  Further  Assurances.  Purchaser and Seller agree that,  from
time to time after Closing, and upon request,  they shall execute,  acknowledge,
and  deliver  such other  instruments  as  reasonably  may be  required  to more
effectively  transfer and vest in Purchaser  the TeleSite  Stock or to otherwise
carry out the terms and conditions of this Agreement.
