to Rako in writing and as set forth herein and in Schedule 4.3, and other than
according to the ordinary and usual course of Centra's business, consistent with
such practice, (a) Centra has engaged only in its routine daily business since
the date of its financial statements, and (b) there has not been any material
adverse change in the business operations, assets, properties, prospects or
condition (financial or otherwise) of Centra taken as a whole, from that

properties or assets, or which if determined against Centra, would have a
material adverse effect against Centra, or which might result in any liability
on the part of Centra, or which questions the validity of this Agreement or of

required to be made nor are any consents, registrations, approvals, permits,
authorizations or designations required to be obtained by Centra from any court,
governmental or regulatory authority, agency, commission, body or other
governmental entity, in connection with the execution and delivery of this
Agreement by Centra or the carrying out and consummation of any transactions

                                      -13-
<PAGE>

         applicable state laws and its certificate of incorporation, by-laws and

         provided to Rako or any such director or officer in respect of the
         following:

                  (i) any matter alleging a violation of the 1933 Act or 1934
                  Act in respect of events or filings made with the SEC, NASD,
                  NASDAQ, any State agency or any stock exchange prior to the
                  Closing;

                  (ii) any matter alleging a breach of Rako's representations,

         fees), judgments, fines, losses, claims, demands, liabilities, damages
         and deficiencies, including interest and penalties, incurred or
         suffered in connection with any claim action, suit, proceeding or
         investigation, whether civil, criminal or administrative, arising out
         of matters existing or occurring prior to the Closing, whether asserted
         or claimed prior to, at or after the Closing, which is based in whole
         or in part on, or arising in whole or in part out of the fact that such
         person is or was a director or officer of Rako including, without
         limitation, all losses, claims, damages, costs, expenses, liabilities,
         judgments or settlement amounts based in whole or in part on, or
         arising in whole or in part out of, or pertaining to this Agreement or
         the transactions contemplated hereby to the fullest extent that Centra
         could have been permitted under applicable state laws and its
         certificate of incorporation, by-laws and other agreements in effect on
         the date hereof to indemnify such individual. Notwithstanding the
         foregoing, no indemnity shall be provided to Centra or any such
         Shareholder, director or officer in respect of the following:

                  (i) any matter alleging a breach of Centra's representations,
                  warranties and/or covenants in this Agreement; or

                  (ii) any matter alleging the Shareholder, director or officer
                  willfully acted in violation of his duty under applicable law.

         (c) Any indemnified party wishing to claim indemnification under
         subsection (a) or (b) of this Section 6.4, upon leaning of any such
         claim, action , suit, proceeding or investigation, will promptly notify
         Centra if under subsection (a), or Rako if under subsection (b), but
         failure to so notify the appropriate party will not relieve the
         indemnifying party from any liability which it may have under this
         Section 6.4 except to the extent such failure materially prejudices
         such party. In the event of any such claim, action, suit, proceeding or
         investigation, (i) the indemnifying party will have the right to assume
         the defense thereof and will not be liable to any such indemnified
         party in connection with the defense thereof, (ii) the indemnified
         party will cooperate in all respects as requested by the indemnifying
         party in the defense of any such matter, and (iii) the indemnifying
         party will not be liable for any settlement effected without its prior
         written consent, which consent will not be unreasonably withheld;
         provided, however, that the indemnifying party will not have any
         obligation hereunder to any indemnified party if and when a court will
         ultimately determine, and such determination will have


                                      -14-
<PAGE>

         become final, that the indemnification of such indemnified party in the
         manner contemplated hereby is prohibited by law.

SECTION 6.5. Confidentiality. All parties hereto agree to keep confidential this
Agreement and all information and documents relating to this Agreement until
such time as the Agreement and the transactions contemplated hereunder are made
public by means of an appropriate press release or by any other means reasonably
assured to make such information publicly available.
