                  (D) Any party claiming a right to indemnification hereunder
         (the "Indemnified Party") shall give the other party from whom
         indemnification is sought (the "Indemnifying Party") prompt written
         notice of any claim, demand, action, suit, proceeding or discovery of
         fact (any of which shall be a "Claim") upon which the Indemnified Party
         intends to base a claim for indemnification under this Article III,
         Section 2, provided, however, that no failure to give such notice shall
         excuse any


                                       11
<PAGE>   12

         Indemnifying Party from any obligation hereunder except to the extent
         the Indemnifying Party is materially prejudiced by such failure. The
         Indemnified Party shall not settle or compromise any Claim by a third
         party without the prior written consent of the Indemnifying Party,
         which will not be unreasonably withheld or delayed, unless suit in
         respect of such Claim shall have been instituted against the
         Indemnified Party and the Indemnifying Party shall not have chosen to
         participate in the defense of such suit after notification thereof if
         the Indemnifying Party is entitled to participate under paragraph (E)
         of this Section.

                  (E) In connection with any Claim resulting from or arising out
         of any claim or legal proceeding by a third party, the Indemnifying
         Party, may, upon written notice to the Indemnified Party within 15 days
         following the Indemnified Party's notice of the Claim, assume the
         defense of any such action with its own counsel and its own expense if
         the Indemnifying Party acknowledges to the Indemnified Party in writing
         its obligation to indemnify the Indemnified Party pursuant to this
         Article III, Section 2 in respect of such Claim; provided, however,
         that such counsel is reasonably acceptable to the Indemnified Party and
         provided, further, that if, in the reasonable opinion of the
         Indemnified Party, for any conflict of interest that may arise between
         the Indemnifying Party and the Indemnified Party, the Indemnified Party
         may retain independent counsel at the expense of the Indemnifying
         Party. If the Indemnifying Party assumes the defense or prosecution of
         any such action or proceeding, it shall take all steps reasonably
         necessary in the defense, prosecution and settlement of such action or
         proceeding. The Indemnifying Party shall not, in the defense or
         prosecution of any such action or proceeding except with the written
         consent of the Indemnified Party, consent to the entry of any judgment
         or enter into any settlement which does not include as an unconditional
         term thereof, a release by the third party of the Indemnified Party
         from all liability in respect of the matter which is the subject of
         such action or proceeding. The Indemnified Party shall cooperate in the
         defense or prosecution of any such action or proceeding; provided that
         the Indemnifying Party shall pay or reimburse the Indemnified Party for
         any actual costs or expenses attributable to such cooperation.

                  (F) The obligations of the Company pursuant to paragraph (B)
         of this Section and the obligations of the Buyer pursuant to paragraph
         (C) of this Section shall, in each case be limited to an aggregate
         amount not in excess of the Purchase Price. Neither the Company nor the
         Buyer shall make any Claim hereunder unless and until the aggregate
         amount of such Claim exceeds $25,000; provided, however, that if the
         aggregate amount of Claims by the Buyer or the Company, respectively,
         exceeds $25,000, the obligations of the Company or the Buyer,
         respectively, hereunder shall be with respect to the entire amount of
         such Claims.

LABAMERICA SHAREHOLDERS, IN AGGREGATE BASED ON THEIR PRO-RATA RESPECTIVE
OWNERSHIP INTERESTS IN THE COMPANY AS DESCRIBED IN THESE EXHIBITS, ARE ENTITLED
TO RECEIVE WARRANTS TO PURCHASE COMMON STOCK OF PARENT, COMPUTED IN THE
