under the direction of a Board of Directors (the  "Board"),  which shall consist
of not more than eight members  unless Suez should fail or be unable to exercise
its right to designate a director  pursuant to this  Section,  in which case the
Board shall  consist of not more than seven  members.  The  Stockholders  hereby
agree  to use  their  best  efforts  and to take  all  reasonably  necessary  or
desirable   actions  within  their  power,   whether  in  their   capacities  as
stockholders,  directors, members of a board committee,  officers of the Company
or  otherwise  (including,  but not  limited to, the voting of shares of Company
Stock owned by them,  attendance  at meetings in person or by proxy for purposes
of obtaining a quorum and  execution of written  consents in lieu of  meetings),
and the Company shall take all reasonably  necessary or desirable actions within
its  control  (including,   without   limitation,   calling  special  board  and
stockholder meetings) to effectuate and carry out the following provisions:

                  (a) The Stockholders  shall be entitled to  representation  on

                           Federal  Reserve System,  12 C.F.R.  225, if it shall
                           elect  in  writing  to  the   Company,   Suez  Equity
                           Investors L.P., a Delaware limited partnership, shall
                           have the right to designate one director.

securities  of the  Company  owned by them  for the  election  of the  directors
designated in accordance with this Section 2.1(a) or to cause the directors then

representative  to attend and observe  meetings  of the Board and any  committee
thereof and (b) receive all information and consents distributed to directors.

                  (b) A director  may be removed  only if the Person or Persons,
if any,  entitled to designate  such director  pursuant to Section 2.1(a) hereof
delivers  a written  notice to the  Company  stating  that such  director  shall
forthwith be removed and replaced with a substitute  director designated in such

                  (c) In the event  that any  vacancy is created on the Board by

designated by the Person or Persons,  if any, entitled to designate the director
whose  death,  resignation  or  removal  created  such  vacancy  and each of the
Stockholders shall cause its designated directors to elect the person designated
to fill the vacancy.

                  (d) Any  committee  of the Board will be  constituted  to give
each of IESI Capital,  EOF Delaware,  TCC and Thayer  representation  thereon at
least proportionate to their representation on the Board.

compensation from the Company for service as a director; provided, however, that
all reasonable  out-of-pocket  expenses of each director `incurred in connection
with  attending  regular and special board meetings and any meeting of any board
committee shall be paid by the Company.

         2.2 CERTAIN  RESTRICTIONS.  No Stockholder shall grant any proxy, enter
into or agree to be bound by any voting trust  agreement or  arrangement  of any
kind with respect to any voting  securities  of the  Company,  or enter into any
stockholder agreements or arrangement of any kind with respect to any Securities
of the  Company,  any of  which is  inconsistent  with  the  provisions  of this
Agreement,  including,  but not limited to, any  agreement or  arrangement  with

         3.1      GENERAL RESTRICTIONS ON TRANSFER.
                  ---------------------------------

                  (a)  Except  as  otherwise  provided  in  this  Agreement,  no
Stockholder  shall directly or indirectly  effect a Transfer of any Shares owned
or held by such  Stockholder  unless  (i) such  Transfer  is (A) to a  Permitted
Transferee (other than Transfers to another Stockholder that is not an Affiliate
of  the  transferring  Stockholder  or  Transfers  that  are  consummated  after
compliance  with the  provisions  of Section  4.1,  Section  5.1 or Section  5.2
hereof) or (B) a Permitted Thayer Transfer, (ii) the certificate or certificates
representing  such Shares bear a legend as provided in Section 7.2 hereof to the

                                       11
<PAGE>

effect that such Shares are not  registered  under the Act and that the Transfer
thereof  is  subject  to the  terms  of  this  Agreement,  (iii)  the  Permitted
Transferee  shall have executed,  as a condition to obtaining  ownership of such
Shares, an instrument  substantially in the form attached hereto as Exhibit B (a
"Joinder Agreement") in which the Permitted Transferee agrees that its ownership
of such  shares of Company  Stock  shall be subject  to, and that the  Permitted
Transferee  will comply with,  all of the terms and conditions of this Agreement
and in which the  Permitted  Transferee  confirms that the  representations  and
warranties  contained in Section 7.1(a) hereof are true and correct with respect
to such Permitted Transferee as of the date of such Joinder Agreement,  and (iv)
such Joinder  Agreement  shall have been promptly  delivered to the Board of the
Company prior to the acquisition by such Permitted Transferee of such Shares. As
used herein,  "Permitted  Thayer Transfer" shall mean a sale by TCC3 of Series E
Preferred  Stock  pursuant  to Section  8.2 of the  Purchase  Agreement.  Such a
Permitted  Transferee or transferee in a Permitted  Thayer  Transfer that is not
already  a party  to  this  Agreement,  by  executing  a  Joinder  Agreement  as
hereinabove provided, shall become a party to this Agreement and shall be deemed
a Stockholder for purposes hereof.  Notwithstanding the foregoing, a Stockholder
may effect a Transfer of Shares owned or held by such  Stockholder  (i) pursuant
to a Public Sale, or (ii) to the Company, in a transaction that is incidental to
(A) the exercise,  conversion or exchange of such Shares in accordance  with the
terms of such  Shares,  (B) a  combination  of such Shares  (including a reverse
stock split), or (C) a recapitalization,  reorganization or reclassification, or
merger or  consolidation  involving  the Company or the Shares  (each a "Company
Transfer").

                  (b) No  Stockholder  shall  directly  or  indirectly  effect a
Transfer of any Shares  owned or held by such  Stockholder  if such action would
constitute a violation of any federal securities laws or any state securities or
blue sky laws or a breach of the conditions  under which such Transfer is exempt
from  registration  under  any  such  laws or a  breach  of any  undertaking  or
agreement on the part of such  Stockholder made or entered into pursuant to such
laws or in connection with obtaining an exemption from registration  thereunder.
Such  Stockholder  shall  deliver  to the  Company a written  opinion of counsel
acceptable to the Company, in form and substance reasonably  satisfactory to the
Company,  to the  effect  that  the  Transfer  of such  Shares  is  exempt  from
registration  under the Act and  applicable  state  securities  laws;  provided,
however,  that in the event of a Permitted Thayer Transfer, a Transfer of Shares
between any of Suez, EOF, Sanders I, Sanders II (or their respective  successors
or  assigns   hereunder)  and  any  of  their  respective   Affiliates  who  are
Stockholders;  IESI  Capital  and any of the  other  entities  included  in such
definition  hereunder;  and  between or among  Thayer,  TCC2,  TCC 3 and TCC, no
opinion  of  counsel  shall  be  required,  unless,  in any  case,  the  Company
reasonably requests such an opinion. The Company shall promptly advise a selling
Stockholder   whether  such  opinion  of  counsel  is  in  form  and   substance
satisfactory to the Company.

                  (c) The Company  shall refuse to record in its stock  transfer
books a Transfer  by any  Stockholder  of any  Shares  that is not  effected  in
compliance  with this Agreement,  and any such attempted  Transfer shall be null
and void.

         4.1      FIRST OFFER RIGHT.
                  ------------------

                  (a) At least  thirty (30) days prior to making any Transfer of
any Company Stock (other than in a Public Sale, a Permitted Thayer Transfer,  to
a  Permitted  Transferee  (but not  Transfers  to a  Stockholder  that is not an
affiliate of the transferring Stockholder (the "Transferring Stockholder")) or a
Company Transfer),  the Transferring  Stockholder shall deliver a written notice
(an "Offer  Notice")  to the  Company  and the other  Stockholders  (the  "Other
Stockholders").  The Offer  Notice  shall  disclose  in  reasonable  detail  the
proposed  number of shares of  Company  Stock to be  transferred  (the  "Offered
Stock"),  the proposed  terms and conditions of the Transfer and the identity of
the prospective  transferee(s)  (if any). The Company shall promptly  provide to
any  Stockholder,  upon  written  request  to the  Company  for the  purpose  of
delivering  an  Offer  Notice,  a  list  of  names  and  addresses  of  all  the
Stockholders.  First,  the Company may elect to purchase  all (but not less than
all) of the Offered Stock  specified in the Offer Notice at the price and on the
terms  specified  therein by delivering  written  notice of such election to the
Transferring  Stockholder and the Other Stockholders as soon as practical but in
any event  within ten (10) days after the delivery of the Offer  Notice.  If the
Company does not elect to purchase all of the Offered Stock within such ten (10)
day  period,  each  Other  Stockholder  may elect to  purchase a portion of such
Offered  Stock at the price and on the terms  specified  in the Offer  Notice by
delivering  written notice of such election to the  Transferring  Stockholder as
soon as practical,  but in any event within  twenty (20) days after  delivery of
the Offer  Notice,  provided that the rights  granted to the Other  Stockholders
under  this  Section   4.1(a)  shall  only  exist  if  the  Other   Stockholders
collectively  elect to  purchase  all (or more than all as  provided in the next
sentence) and not less than all of the Offered Stock. If the Other  Stockholders
have in the  aggregate  elected  to  purchase  more than the number of shares of
Offered Stock being offered by the Transferring  Stockholder,  the Offered Stock
shall be allocated among the Other Stockholders  electing to purchase Shares pro
rata based upon the number of Shares elected to be purchased.  Any Offered Stock
not elected to be  purchased  by the end of such twenty (20) day period shall be
re-offered  by the  Transferring  Stockholder,  for  the  ten  (10)  day  period
following the expiration of such twenty (20) day period,  on a pro rata basis to
the Other  Stockholders  who have elected to purchase  Offered Stock and, if any
Offered Stock remains after such  re-offering,  the Company shall have the right
to  purchase  such  remaining  Offered  Stock.  If  the  Company  or  any  Other
Stockholders  have elected to purchase all (but not less than all) Offered Stock
from  the  Transferring  Stockholder,  the  transfer  of such  Shares  shall  be
consummated as soon as practical after the delivery of the election notice(s) to
the  Transferring  Stockholder,  but in any event within fifteen (15) days after
the expiration of the final applicable election period.

                  (b) If the Company and the Other Stockholders have not elected
to purchase all of the Offered Stock, the  Transferring  Stockholder may, within
sixty (60) days  after the  expiration  of the  applicable  election  period and
subject to the provisions of Section 5.1 hereof,  Transfer such Offered Stock to
one or more third parties at a price no

                                       13
<PAGE>

less than the price per Share  specified  in the Offer Notice and on other terms
no more favorable to the transferees thereof than offered to the Company and the
Other Stockholders in the Offer Notice. Any Offered Stock not transferred within
such sixty (60) day period  shall be  re-offered  to the  Company  and the Other
Stockholders under Section 4.1(a) above prior to any subsequent Transfer.

                  (c) At any  closing  pursuant  to Section  4.1(a)  above,  the
Company  and/or the  relevant  Other  Stockholder(s),  as the case may be, shall
deliver to the Transferring Stockholder the full amount of the purchase price of
the Offered Stock (any cash portion thereof to be paid in immediately  available
funds),  and the  Transferring  Stockholder  shall  execute  and  deliver to the
Company or the relevant Other  Stockholder(s)  certificate(s)  representing  the
Shares being transferred,  free of any liens, claims or encumbrances (other than
those imposed by Federal or state securities laws and this Agreement),  and such
duly executed stock powers or other  instruments of conveyance as the Company or
the relevant Other Stockholder(s),  as the case may be, shall reasonably request
to convey title to the Offered Stock. The Transferring Stockholder shall pay any
applicable  federal,  state or  local  taxes  incurred  in  connection  with the
foregoing transfer.

         4.2 PLEDGE OF SHARES. A Stockholder  shall have the right to pledge any
shares of Company  Stock owned or held by such  Stockholder  to the  Company,  a
commercial  bank,  savings and loan  association  or other  lending or financial
institution  as security for any  indebtedness  of such  Stockholder;  provided,
however,  that no such pledge  shall be made unless (a) the Person to which such
pledge is made shall have executed an appropriate  document in which such Person
agrees that,  in the event of  realization  upon such Shares,  such Shares shall
continue to be subject to the terms and  conditions  of this  Agreement and that
such Person will not effect any  Transfer  of such Shares  except in  compliance
with the  provisions  hereof as if such Person was a  Stockholder,  and (b) such
document shall have been promptly delivered to, and shall have been approved by,
the Company  prior to the pledge of such  Shares,  which  approval  shall not be
unreasonably withheld.

                        TAG ALONG AND BRING ALONG RIGHTS
                        --------------------------------

         5.1 TAG ALONG  RIGHTS.  In the event that any  Stockholder  or group of
Stockholders  (such Stockholder or Stockholders,  together with their respective
Permitted  Transferees,  shall be  hereinafter  referred  to as the  "Article  V
Sellers")  proposes to Transfer in a single  transaction  or a series of related
transactions  to any Person or group of Persons (other than to any Person who is
a Stockholder as of the date hereof or a Permitted Transferee) other than in any
Company  Transfer,  Permitted Thayer Transfer,  Public Sale or a Transfer to the
Company  or  another  Stockholder   pursuant  to  Section  4.1,  Paid-In  Shares
representing an amount equal to or greater than five percent (5%) of the Paid-In
Shares in the  aggregate,  the  Article V Sellers  shall  first  comply with the
following:

                                       14
<PAGE>

                  (a) The Article V Seller or Sellers shall give written  notice
(the  "Article V Notice") to the Company and each  Stockholder  identifying  the
number of Paid-In  Shares it desires to Transfer (the  "Article V Shares"),  the
intended  method of the  Transfer,  the price such  Article V Seller  desires to
receive for such Article V Shares,  the proposed  transfer  date,  and all other
pertinent terms thereof, including, if known, the identity of any proposed buyer
or buyers of such Article V Shares.  The Company shall  promptly  provide to any
Stockholder,  upon written request to the Company, for the purpose of delivering
an  Article  V  Notice,  a  list  of  the  names  and  addresses  of  all of the
Stockholders.  For purposes hereof,  a bona fide third-party  tender or exchange
offer to  purchase  shares of  Company  Stock  shall be deemed to be an offer to
purchase  such  Shares at the price  specified  therein,  without  regard to any
provisions  thereof with respect to proration  or  conditions  to the  offeror's
obligation to purchase.

                  (b)  Any  Stockholder  that  is not an  Article  V  Seller  (a
"Participant")  may  elect  to  participate  in  the  contemplated  Transfer  by
delivering a written  notice to the Company and the Article V Seller or Sellers,
within  thirty (30)  Business  Days (the "Option  Period")  after receipt of the
Article V Notice,  specifying  the number of  Paid-In  Shares  such  Participant
elects to sell. Each such  Participant may elect to Transfer in the contemplated
transaction,  at the same price and on the same terms, up to a number of Paid-in
Shares  equal to the product of (i) the  quotient  determined  by  dividing  the
percentage  of  Paid-In  Shares  owned  by  such  Stockholder  by the  aggregate
percentage of Paid-In Shares owned by the Article V Sellers and all Participants
and (ii) the number of Paid-in Shares to be sold in the proposed transaction. If
the Participants and the Article V Sellers (singularly,  a "Selling Party," and,
collectively,  the "Selling  Parties") in the aggregate  elect to sell more than
the total  number of Paid-In  Shares that the  proposed  buyer or buyers wish to

buyers  that  number of Shares  equal to the number of  Paid-In  Shares to be so
purchased  by such buyer or buyers  from the  Selling  Parties  multiplied  by a
fraction  the  numerator  of which is the number of Paid-in  Shares such Selling
Party elects to sell and the  denominator  of which is the  aggregate  number of
Paid-in Shares all of such Selling Parties elect to sell.

                  (c) Each  Article V Seller and  Participant  shall  effect its

or  Participant  is entitled to sell pursuant to this Section 5.1. All shares of
Company  Stock  proposed  to  be  transferred  by  each  Article  V  Seller  and
Participant  shall be  transferred  free  and  clear of all  liens,  claims  and
encumbrances  of any kind  (other  than  those  imposed  by  federal  and  state
securities  laws and this  Agreement) and such Article V Seller and  Participant
shall, if requested, deliver certificates to such effect.

Proposing Stockholder, the Proposing Stockholder(s),  at its option, may require
that (i) each  other  Stockholder  sell or  exchange  a Like  Percentage  of its
Paid-In  Shares in the same  transaction at the same price and on the same terms
and  conditions  as  applicable  to the  Proposing  Stockholder(s),  and (ii) if

cooperate with and take all necessary and desirable  actions in connection  with
the  consummation  of  such  Bring  Along  Sale,  including  without  limitation
executing  and  delivering  (A) a purchase and sale  agreement in the form to be

subject to the conditions that upon consummation of the Bring Along Sale, all of
the  holders  of  Common  Stock  will  receive  the  same  form  and  amount  of
consideration  per share of Common Stock,  all of the holders of the same series
of Preferred  Stock will receive the same form and amount of  consideration  per
share of such series of  Preferred  Stock,  and if any holder of Common Stock or
any  series of  Preferred  Stock is given an option as to the form and amount of
consideration  to be received,  all holders of such stock will be given the same
option.

                  (b) The Proposing  Stockholders shall give written notice (the
"Bring  Along  Notice")  to  each of the  other  Stockholders,  identifying  the
proposed  buyer or buyers,  a description of the Bring Along Sale, the number of
shares of Company Stock to be transferred,  the amount and type of consideration
to be paid, the proposed  transfer date and all other pertinent terms thereof no
later than fifteen (15) days prior to such proposed  transfer  date. The Company

the Company for the purpose of  delivering a Bring Along  Notice,  a list of the
names and addresses of all of the Stockholders.

                  (c) On the closing date of a Transfer pursuant to this Section
5.2, the Proposing Stockholders and the other Stockholders shall sell the shares
of Company  Stock owned by them to the buyer or buyers  designated  in the Bring
Along  Notice  on  the  terms  and   conditions   acceptable  to  the  Proposing
Stockholders  which  shall be at least as  favorable  as those  set forth in the
Bring Along Notice.  By execution of this  Agreement,  each  Stockholder  hereby
irrevocably  designates and appoints the Proposing  Stockholders,  or any one of
them, as its attorney in fact to transfer such  Stockholder's  shares of Company

Stockholder)  pursuant to this Section  5.2.  All shares of Company  Stock to be
Transferred by each  Stockholder  pursuant to this Section 5.2 shall be free and
clear of all  liens,  claims  and  encumbrances  of any kind  (other  than those

Stockholder shall, if requested, deliver certificates to such effect.

                                ISSUANCE OF STOCK
                                -----------------

         6.1 RIGHTS UPON ISSUANCE OF ADDITIONAL SECURITIES.  Except as otherwise
provided in Section  6.1(e),  the Company hereby grants to each  Stockholder the
following  rights with respect to any and all proposed  issuances of  Additional
Securities by the Company:

                  (a) The Company shall give each Stockholder  written notice of
the Company's intention to issue Additional  Securities (the "Issuance Notice"),
describing the type of Additional Securities,  the price at which the Additional
Securities will be issued and the general terms upon which the Company  proposes
to issue the  Additional  Securities,  including  the  anticipated  date of such
issuance.

                  (b) Each Stockholder shall have twenty (20) Business Days from
the date it receives the Issuance Notice to agree to purchase all or any portion
of its Pro Rata Portion of such  Additional  Securities by giving written notice
to the Company of its desire to purchase  Additional  Securities  (the "Response
Notice")  and  stating  therein  the  quantity of  Additional  Securities  to be
purchased.  Such Response Notice shall  constitute the irrevocable  agreement of
such Stockholder to purchase the quantity of Additional  Securities indicated in
the  Response  Notice at the price  and upon the  terms  stated in the  Issuance
Notice; provided,  however, that if the Company is proposing to issue Additional
Securities for consideration other than all cash, and subject to the limitations
on the rights set forth in this Section  6.1(e),  the Company  shall accept from
such Stockholder either non-cash consideration which is reasonably comparable to
the  non-cash  consideration  proposed  by the Company or the cash value of such
non-cash  consideration.  Any purchase by a Stockholder of Additional Securities
shall be  consummated  on or prior to the  later of the date on which  all other
Additional  Securities described in the applicable Issuance Notice are issued or
the  tenth  Business  Day  following  delivery  of the  Response  Notice by such
Stockholder.

                  (c) The Company shall have one hundred  twenty (120) days from
the date of the
Issuance   Notice  to  consummate  the  proposed   issuance  of  the  Additional
Securities,  which the  Stockholders  have not elected to  purchase  pursuant to
Section  6.1(b).  Notwithstanding  the  foregoing,  the  Company  may  sell  the
Additional  Securities  which the  Stockholders  have not  elected  to  purchase
pursuant to a Response  Notice at a price and upon terms that are less favorable
to the Company than those  specified in the Issuance  Notice;  provided that any
purchase of Additional Securities by the Stockholders consummated at the time of
such issuance,  pursuant to the last sentence of Section  6.1(b),  shall be upon
the same less favorable terms;  provided,  further that if a Stockholder did not

                                       17
<PAGE>

elect to purchase  any or all of its Pro Rata Portion of  Additional  Securities
based upon the terms  specified in the  relevant  Issuance  Notice,  the Company
shall provide such Stockholder  with a revised  Issuance Notice  reflecting such
less favorable terms, and each such Stockholder shall have fifteen (15) Business
Days from the date such  Stockholder  receives such revised  Issuance  Notice to
agree to purchase all or any portion of its Pro Rata Portion of such  Additional
Securities to be issued upon the less  favorable  terms set forth in the revised
Issuance  Notice  by  giving  written  notice to the  Company  of its  desire to
purchase  such  Additional  Securities  and  stating  therein  the  quantity  of
Additional  Securities  to be  purchased.  In the event the Company  proposes to
issue  Additional  Securities  after such one hundred eighty (180) day period or
Additional  Securities in addition to those specified in the Issuance Notice, it
must again comply with the procedures set forth in this Section 6.1.

                  (d) In the event the  Company  grants to any Person  rights to
participate  in any issuances of Securities  which are more  favorable  than the
rights  granted to the  Stockholders  in this Section 6.1, the rights granted to
the  Stockholders  shall be expanded to the extent necessary to make such rights
no less  favorable  than the  rights  granted to such  other  Person;  provided,
however,  that the foregoing provisions shall not apply to the rights granted by
the Company to any  underwriter  to acquire  Securities to be issued and sold by
the Company in a Public Offering.

                  (e) Notwithstanding  the foregoing  provisions of this Section
6.1, the Stockholders shall not have the right to participate in (i) the sale of
up to  55,000  shares of  Series E  Preferred  Stock  pursuant  to the  Purchase
Agreement  (as the same may be amended,  modified or  supplemented  from time to
time, by the addition of additional  Purchasers thereunder or otherwise) or (ii(
the issuances of any  Securities (A) made as part of the  consideration  paid by
the Company in any merger, consolidation, combination, acquisition of securities
of another corporation or purchase of any business or assets for such securities
by or with the Company;  provided that the Board shall have  determined,  in its
sole discretion by resolution  approved by the Board,  that the consideration to
be  received  by the  Company in such  issuance is not less than the fair market
value of the  Securities to be issued in such  transaction;  provided,  further,
that  no  Stockholder  or  Affiliate  thereof  shall  own  any  interest  in the
corporation  or  entity  with  whom  the  merger,  consolidation,   combination,
acquisition or purchase of assets is consummated,  unless such Stockholder is an
executive officer of the Company on such date and will be employed by the entity
with which the merger,  consolidation,  combination,  acquisition or purchase of
assets transaction is consummated after the date of such transaction; or (B) any
Securities issued or issuable to any employees,  officers or directors  pursuant
to any Employee Plan approved by the Board.

         SECURITIES LAWS AND MAY NOT BE OFFERED,  SOLD, TRANSFERRED OR OTHERWISE
         DISPOSED OF OR PLEDGED OR HYPOTHECATED  UNLESS REGISTERED UNDER THE ACT
         AND ANY APPLICABLE  STATE  SECURITIES  LAWS OR UNLESS AN EXEMPTION FROM
         REGISTRATION UNDER THE ACT AND ANY SUCH LAWS IS AVAILABLE (AND, IN SUCH
         CASE,  AN OPINION OF COUNSEL  ACCEPTABLE  TO THE  COMPANY,  IN FORM AND
         SUBSTANCE  REASONABLY  SATISFACTORY  TO THE  COMPANY,  SHALL  HAVE BEEN

         DISPOSITION,   PLEDGE  OR   HYPOTHECATION   THEREOF   IS  EXEMPT   FROM
         REGISTRATION UNDER THE ACT AND ANY SUCH LAWS).

         THE  SHARES  REPRESENTED  BY THIS  CERTIFICATE  ARE  SUBJECT TO CERTAIN
         RESTRICTIONS  ON  TRANSFER  AS SET  FORTH  IN THE  SECOND  AMENDED  AND

         SHARES  REPRESENTED  BY THIS  CERTIFICATE  WITHOUT  CHARGE UPON WRITTEN
         REQUEST TO THE COMPANY AT ITS PRINCIPAL PLACE OF BUSINESS OR REGISTERED

         COMPLIED WITH."

         7.3  TERMINATION  UPON  PUBLIC  OFFERING OR SALE  TRANSACTION.  If this
Agreement has not previously  been  terminated by the written consent of all the
Stockholders  then party hereto,  this  Agreement,  except for the provisions of
Section 2.1, shall  terminate  upon the effective  date of a Public  Offering or
Sale Transaction. In addition, upon the request of the underwriter in connection
with an initial Public Offering,  the Stockholders  will discuss the termination
of Section 2.1.

         7.4 AMENDMENT; WAIVER. The provisions of this Agreement may be amended,
and  compliance  with the  provisions  hereof may be  waived,  only by a written
instrument executed by Stockholders  holding not less than seventy percent (70%)
of the Paid-In Shares and the Company; provided, however, that the Agreement may
be amended to add a new  Stockholder  as a party  hereto by the Company and such
new Stockholder executing and delivering a Joinder Agreement.  No failure on the
part of any party to exercise any right,  power or privilege  granted  hereunder
shall  operate as a waiver  thereof,  nor shall any  single or partial  exercise
thereof  preclude any other or further  exercise  thereof or the exercise of any
other right, power or privilege granted hereunder.

                  By virtue of the execution hereof, any non-compliance with the
provisions of the Prior Agreements in connection with the issuance of the Series
E Preferred Stock is hereby waived.

         7.5 FURTHER  ASSURANCES.  Each Stockholder agrees to do, or cause to be
done,  such further acts and to execute and deliver,  or to cause to be executed
and delivered,  such further  agreements,  instruments,  certificates  and other
documents as may be necessary or  appropriate  to  effectuate  and carry out the
purposes of this Agreement.

         7.6 NOTICES. All notices and other communications hereunder shall be in
writing and shall be given by delivery in person,  by  registered  or  certified
mail (return receipt requested and with postage prepaid thereon) or by facsimile
transmission  to the parties at their  respective  addresses as reflected in the
Company's records (or to such other address as any party shall have furnished to
the others  pursuant to this Section 7.6). All notices and other  communications
hereunder  that are  addressed  as provided in this  Section 7.6 shall be deemed
duly and validly given, (a) if delivered in person or by overnight courier, upon
delivery,  (b) if delivered by registered or certified  mail,  seventy-two  (72)
hours after being placed in a depository of the United States mails,  and (c) if

delivered by facsimile  transmission,  upon transmission  thereof and receipt of
the appropriate confirmation.

         7.7 BINDING  EFFECT;  ASSIGNMENT.  This Agreement shall be binding upon
and inure to the  benefit  of the  parties  hereto and their  respective  heirs,
assigns, executors, administrators,  personal representatives and successors (it
being understood and agreed that nothing contained in this Agreement is intended
to confer upon any other Person any rights,  benefits or remedies of any kind or
character  whatsoever).  No Stockholder  may assign this Agreement to any Person
(other than a Permitted  Transferee of Shares  previously  owned or held by such
Stockholder  that  acquired the same in compliance  with the  provisions of this
Agreement)  without  the prior  written  consent  of each of the  other  parties
hereto.

         7.8  SEVERABILITY.  In the event that any  provision  set forth in this
Agreement  is found to be  invalid,  illegal  or  unenforceable,  the  validity,
legality and  enforceability  of the remaining terms and provisions hereof shall
not be in any way affected thereby,  and this Agreement shall be construed as if
such  invalid,  illegal or  unenforceable  provision  had never  been  contained
herein.

         7.9 SPECIFIC PERFORMANCE.  The parties hereto agree that a violation of
the provisions hereof would cause  irreparable  injury to the parties hereto for
which they would have no adequate  remedy at law.  Accordingly,  in the event of
any such  violation,  the parties  hereto shall be entitled to  preliminary  and
other injunctive  relief without  necessity of complying with any requirement as
to the posting of a bond or other security.  Any such injunctive relief shall be
in addition to any other  remedies that may now or hereafter be available at law
or in equity.

         7.10 GOVERNING  LAW. This Agreement  shall be governed by and construed

2.       Requested Registrations.
         -----------------------

         (a) If on any three  occasions  on or after the  earlier of the date of
the Company's  initial  public  offering or December 31, 2004, the Company shall
receive from one or more  Initiating  Holders a written request that the Company
effect the  registration  of  Registrable  Common  Stock  representing  at least
fifteen  percent  (15%) of the  Registrable  Common  Stock then  outstanding  or
issuable (or any lesser percentage if the reasonably anticipated aggregate price
to  the  public  of  the  Registrable  Common  Stock  to  be  included  in  such
registration  would exceed $25 million),  in connection  with a firm  commitment
underwriting managed by a nationally recognized underwriter, the Company will:

                  (i) promptly give written notice of the proposed  registration
to all other Stockholders; and

                  (ii) as soon as practicable,  use all commercially  reasonable
efforts to effect such  registration  as may be so requested and as would permit
or  facilitate  the sale and  distribution  of such portion of such  Registrable
Common Stock as are specified in such request, together with such portion of the
Registrable  Common Stock of any  Stockholder  or  Stockholders  joining in such
request as are  specified in a written  request  given within  thirty days after
receipt of such written notice from the Company. If the underwriter managing the
offering  advises  the  Stockholders  who  have  requested  inclusion  of  their
Registrable  Common Stock in such  registration  that  marketing  considerations
require a limitation on the number of shares offered,  such limitation  shall be
imposed pro rata among such Stockholders who requested  inclusion of Registrable
Common Stock in such registration  according to the number of Registrable Common
Stock  owned by each of such  Stockholders.  Neither  the  Company nor any other
Person (excluding  Stockholders)  may include shares in a registration  effected
under this Section 2 without the consent of the Stockholders  holding a majority
of the  shares  of  Registrable  Common  Stock  sought  to be  included  in such
registration  if the  inclusion  of shares by the  Company or the other  Persons
would, in the judgment of the managing  underwriter,  limit the number of shares
of Registrable  Common Stock sought to be included by the Stockholders or reduce
the offering  price thereof.  No  registration  initiated by Initiating  Holders
hereunder  shall count as a  registration  under this  Section 2: (1) unless and
until it shall have been declared effective,  and (2) if such Initiating Holders
fail to Register and sell at least 67% of the Registrable Common Stock requested
to be included in such registration by such Initiating  Holders in their initial
registration request relating to such registration.

                                      -4-
<PAGE>

         (b)  Notwithstanding the provisions of subparagraph (a) of this Section
2,  the  Company  shall  not be  obligated  to take any  action  to  effect  any
registration pursuant thereto:

                  (i)  Within  the  120-day  period  immediately  following  the
effective  date  of  the   registration   statement   pertaining  to  the  first
underwritten  public  offering of  securities of the Company for its own account
(other than a registration relating solely to a transaction under Rule 145 under
the Act or a registration relating solely to employee benefit plans);

                  (ii)  After  the  Company  has  effected  three  registrations
pursuant to this Section 2, and such registrations have been declared or ordered
effective  and have not been  withdrawn  or  suspended  during the first 90 days
after such registrations have been declared or ordered effective; or

                  (iii) If at the time of the request,  the  Initiating  Holders
could sell all of the Registrable  Common Stock requested to be Registered under
Rule 144 without restrictions.

         (c) The  holders of a  majority  of the Common  Stock  included  in any
registration  requesting  registration under this Section 2 shall have the right
to select the  investment  banker(s) and  manager(s) to administer the offering,
subject to the Company's  approval,  which shall not be  unreasonably  withheld,
provided that, unless the Company otherwise consents, the lead investment banker
shall be from one of the ten firms, which in the immediately  preceding calendar
year managed the ten highest volumes of equity security offerings or a firm that
has previously managed or administered (alone or with others) an equity security
offering for the Company.

         (d) Except for the rights to request the Company to Register any equity
securities of the Company  granted to certain  stockholders of the Company under
the Second  Amended  Agreement,  the Company  shall not grant to any Persons any
rights to request the Company to Register any equity  securities of the Company,
or any securities  convertible  or  exchangeable  into or  exercisable  for such
securities,  unless such rights are  expressly  designated  as  subordinate  and
junior to  (including,  without  limitation,  rights with respect to underwriter
cutbacks or similar limitations) those granted hereunder.

         (e)  In  the  event  any  holder  of   Registrable   Common   Stock  is
participating in an underwritten  offering  pursuant to a registration  effected
under  Section  2 or 3  hereof,  such  holder  shall be party to the  applicable
underwriting agreement and shall provide customary  representations,  warranties
and other  agreements,  and shall be  responsible  for its pro rata share of any
underwriting fees, commissions or discounts payable to the underwriters.

         (f) If the  Company  (i)  shall  furnish  to the  Initiating  Holders a
certificate,  signed by the President of the Company,  stating that the Board of
Directors  has in good  faith  adopted  a  resolution  stating  that it would be
inimical to the best  interests  of the  stockholders  for a public  offering to
proceed, (ii) desires to postpone filing a registration statement in order to be
able to include in such filing audited year-end financing statements prepared in
the ordinary course of preparing its annual report to stockholders (including on
Form  10-K  or such  other  applicable  form),  or  (iii)  gives  notice  to the
Initiating  Holders,  within  thirty (30) days of the receipt of a request given
pursuant to Section 2(a),  that it is engaged or has fixed plans to engage in an
initial firmly  underwritten  registered public offering within thirty (30) days
of the notice date, then the Company may delay a requested  registration for not
more than 90 days,  provided that such delay may be invoked on not more than two
occasions and on not more than one occasion within any twelve-month period.

                                      -5-

3.       Piggyback Registration Rights
         -----------------------------

         (a)  Piggyback   Registration   Rights.   If  at  any  time  after  the
Registration  Right  Effective Date the Company  proposes to Register any of the
Common  Stock under the Act for sale,  either for its own account or the account
of a Stockholder,  for cash (other than a  registration  on Form S-4, S-8 or any
similar form), it will serve written notice of such proposed registration to the
Stockholders at least 30 days before the anticipated  filing date,  which notice
shall include the number of shares of Common Stock the Company or other security
holder  proposes to Register and, if known,  the proposed  underwriter.  Written
notices served by the Company pursuant to the preceding sentence of this Section
3(a) shall be referred to hereinafter as "Notices."  Subject to the restrictions
and in accordance with the procedures set forth below,  the Company will use its
best  efforts to  include  in any  registration  to which a Notice  relates  all
Registrable  Common Stock with respect to which the Company has received written
requests for inclusion  therein  within 20 days after the receipt of the Notice.
Nothing  set forth in this  Section 3 shall  obligate  the  Company  to file any
registration statement unless the Board of Directors approves such filing.

         (b) Priority on Registrations.

                  (i)  Notwithstanding the provisions of Section 3(a) hereof, in
the case of an underwritten  offering,  the managing underwriter or underwriters
of the  registration  may limit the number of shares of Common Stock included in
the underwritten  offering if, in its or their opinion,  the number of shares of
Common Stock  requested  to be sold in such  underwritten  offering  exceeds the
number that can be sold  without  materially  adversely  affecting  the price at
which such securities could be sold. In the event the number is to be so limited
in the  underwritten  offering,  a  sufficient  number of shares of Common Stock
shall be  eliminated  to reduce the total amount of shares of Common Stock to be
included  in  such  underwritten  offering  to the  amount  recommended  by such
underwriter.  In reducing the amount of shares of Common Stock to be included in
such  underwritten  offering,  the  Company  will  include in such  underwritten
offering (A) first, all shares of Common Stock the Company proposes to sell, (B)
second,  all  Registrable  Common Stock  beneficially  owned by any  Stockholder
requested to be included in the underwritten offering and shares of Common Stock
requested to be included by other holders of Common Stock,  who are stockholders
on the date  hereof and who have  registration  rights in respect  thereof  pari
passu with the registration rights granted hereby, reduced pro rata according to
the  number  of  shares  of  Common  Stock   beneficially  owned  by  each  such
stockholder;  and (C)  third,  other  shares of  Common  Stock  requested  to be
included in such registration.

                  (ii) The  Company  shall use its best  efforts  to enable  the
Registrable  Common Stock of the  Stockholders,  if inclusion in an underwritten
offering is properly  requested,  to be included in such underwritten  offering;
provided,  however,  that the  Company  will not be  required to pay any Selling
Expenses  with respect to the sale of such  Registrable  Common  Stock.  If such
Selling   Stockholder's   Registrable  Common  Stock  is  not  included  in  the
underwritten  offering,  the Company shall  nonetheless  use its best efforts to
enable  such  Selling  Stockholder's  Registrable  Common  Stock  to be  sold in
accordance with the intended  methods of distribution  without  inclusion in the
underwriting, subject to the provision contained in the preceding sentence.

         (c)  Other  Registrations.  If  the  Company  has  previously  filed  a
registration  statement  with respect to  Registrable  Common Stock  pursuant to
Section  2,  and if  such  previous  registration  has  not  been  withdrawn  or
abandoned,  the Company  shall not  announce,  file or cause to be effected  any
other registration of any of its equity securities or securities  convertible or
exchangeable  into or exercisable for its equity securities under the Securities
Act (except on Form S-8 or any successor form),  whether on its own behalf or at
the  request of any holder or holders of such  securities,  until a period of at
least 90 days has elapsed from the effective date of such previous registration.

4.       Restrictions on Public Sale by Purchaser.
         ----------------------------------------

         To the  extent  not  inconsistent  with  applicable  law,  the  Selling
Stockholders agree not to effect any public sale or distribution of Common Stock
(including  Registrable  Common Stock not included in an  underwritten  offering
pursuant to Section  3(b)(ii) above) or a similar security of the Company or any
securities  convertible into or exchangeable or exercisable for such securities,
during the seven days prior to, and during the 90-day  period  beginning on, the
effective  date  of  such  registration   statement  (except  as  part  of  such
registration),  if and to the extent requested in writing (with reasonable prior
notice), by (i) the Company in the case of a non-underwritten public offering by
the Company,  (ii) or the managing underwriter or underwriters in the case of an
underwritten public offering. The Company may impose stop-transfer  instructions
with respect to its Common Stock subject to the  restrictions  in this Section 4
until the end of such 90-day period.

5.       Registration Procedures.
         -----------------------

         Whenever any Registrable  Common Stock is to be Registered  pursuant to
Sections  2 or 3 hereof,  the  Company  will use its best  efforts to effect the
registration  and the sale of such  Registrable  Common Stock in accordance with
the intended  method of  disposition of the Selling  Stockholders  as quickly as
practicable,  and in  connection  with any such  request,  the  Company  will as
expeditiously as possible:

         (a) prepare and file with the Commission a registration statement which
includes  the  Registrable  Common  Stock and use its best efforts to cause such
registration  statement  to become  effective  (provided  that  before  filing a
registration  statement or prospectus or any amendments or supplements  thereto,
the Company shall  furnish to the counsel  selected by the holders of a majority
of the Registrable Common Stock covered by such registration statement copies of
all such documents proposed to be filed, which documents shall be subject to the
review and comments of such counsel);

         (b)  prepare  and  file  with  the  Commission   such   amendments  and
post-effective  amendments to the registration  statement and prospectus used in
connection  therewith  as may be necessary  to keep the  registration  statement
effective  for a period  of not less  than 120 days (or such  shorter  period as
shall  be  necessary  to  permit  the  Selling   Stockholders  to  complete  the
distribution  of  the  Registrable  Common  Stock  to  which  such  registration
statement relates in accordance with their intended methods of distribution) and
to  comply  with  the  provisions  of the  Act  and the  rules  and  regulations
thereunder  with  respect to the  disposition  of all  Registrable  Common Stock
covered by the  registration  statement  for the period  required  to effect the
distribution thereof, but in no event shall the Company be required to do so for
a period of more than 120 days following the effective date of such registration
statement;

         (c)  furnish  to  the  Selling  Stockholders  and  the  underwriter  or
underwriters,   if  any,  and  to  counsel  to  the  Selling   Stockholders  and
underwriters,   without  charge,   such  number  of  conformed   copies  of  the
registration  statement and any post-effective  amendment thereto, upon request,
and  such  number  of  copies  of the  prospectus  (including  each  preliminary
prospectus)  and any  amendments  or  supplements  thereto,  and  any  documents
incorporated  by  reference  therein,  as  the  Selling   Stockholders  or  such
underwriter(s)  may reasonably request in order to facilitate the disposition of
the Registrable  Common Stock being sold by the Selling  Stockholders  (it being
understood  that  the  Company  consents  to the use of the  prospectus  and any
amendment or supplement thereto by the Selling  Stockholders and the underwriter
or  underwriters,  if any,  in  connection  with  the  offering  and sale of the
Registrable  Common  Stock  covered  by  the  prospectus  or  any  amendment  or
supplement thereto);

         (d) notify the Selling  Stockholders and the  underwriters,  if any, at
any time when a prospectus  relating  thereto is required to be delivered  under
the Act,  when the  Company  becomes  aware of the  happening  of any event as a
result of which any prospectus included in such registration  statement

                                      -7-
<PAGE>

(as then in effect) contains any untrue statement of a material fact or omits to
state a material fact necessary to make the statements  therein, in light of the
circumstances  under which they were made,  not  misleading  and, as promptly as
possible  thereafter,  prepare  and  file  with the  Commission  and  furnish  a
supplement or amendment to such  prospectus so that, as thereafter  delivered to
the Selling  Stockholders of such Registrable Common Stock, such prospectus will
not contain any untrue  statement of a material fact or omit to state a material
fact necessary to make the  statements  therein,  in light of the  circumstances
under which they were made, not misleading.

         (e) on or  prior to the date on which  the  registration  statement  is
declared effective,  use its best efforts to Register or qualify the Registrable
Common Stock covered by the registration  statement for offer and sale under the
securities or blue sky laws of each state and other  jurisdiction  of the United
States as the Selling  Stockholders or underwriter  requests in writing,  and to
cooperate with the Selling  Stockholders,  the underwriter or  underwriters,  if
any, and their counsel, in connection therewith; to use its best efforts to keep
each  such  registration  or  qualification  effective,  including  through  new
filings,  or  amendments  or  renewals,  during  the  period  such  registration
statement is required to be kept  effective  and to do any and all other acts or
things   necessary  or  advisable  to  enable  the   disposition   in  all  such
jurisdictions  of  the  Registrable  Common  Stock  covered  by  the  applicable
registration  statement;  provided  that the  Company  will not be  required  to
qualify  generally  to do business in any  jurisdiction  where it is not then so
qualified  or to take any action  which would  subject it to general  service of
process in suits other than those arising out of such  registration  in any such
jurisdiction where it is not then so subject;

         (f)  cooperate   with  the  Selling   Stockholders   and  the  managing
underwriter or  underwriters,  if any, to facilitate the timely  preparation and
delivery of certificates (not bearing any restrictive legends)  representing the
Common Stock to be sold under the registration statement, and enable such Common
Stock to be in such  denominations  and Registered in such names as the managing
underwriter or underwriters, if any, or the Selling Stockholders may request;

         (g) enter into such  customary  agreements  (including an  underwriting
agreement in customary form which, if requested by an underwriter,  will contain
customary contribution  provisions on the part of the Company) and take all such
other  actions  (including,  without  limitation,  delivery of  customary  legal
opinions and  officers'  certificates)  as the Selling  Stockholders  reasonably
request in order to expedite or facilitate the  disposition of such  Registrable
Common Stock;

         (h) make  available  for  inspection  and  copying  by any  underwriter
participating in any disposition  pursuant to such registration  statement,  and
any attorney,  accountant or other agent retained by any such  underwriter,  all
financial and other records, pertinent corporate documents and properties of the
Company, and cause the Company's officers, directors,  employees and independent
accountants to supply all information  reasonably  requested by any such seller,
underwriter,  attorney, accountant or agent in connection with such registration
statement,  as shall be  reasonably  necessary  to enable it to exercise its due
diligence responsibility;

         (i) use its best  efforts to obtain a "cold  comfort"  letter  from the
Company's  independent  public  accountants  in customary form and covering such
matters of the type customarily covered by "cold comfort" letters as the Selling
Stockholders or the underwriter reasonably request;

         (j) otherwise use its best efforts to comply with all applicable  rules
and regulations of the Commission,  and make generally available to its security
holders, as soon as reasonably  practicable,  an earnings statement covering the
period of at least twelve months  beginning  with the first day of the Company's
first  full  calendar  quarter  after  the  effective  date of the  registration
statement,  which  earnings  statement  shall satisfy the  provisions of Section
11(a) of the Securities Act and Rule 158 thereunder;

                                      -8-
<PAGE>

         (k) permit any holder of Registrable  Common Stock which holder, in its
sole  and  exclusive  judgment,  might  be  deemed  to  be an  underwriter  or a
controlling  Person of the Company,  to participate  in the  preparation of such
registration or comparable statement; and

         (l) in the  event of the  issuance  of any stop  order  suspending  the
effectiveness  of a  registration  statement,  or of  any  order  suspending  or
preventing the use of any related  prospectus or suspending the qualification of
any  Common  Stock  included  in such  registration  statement  for  sale in any
jurisdiction, the Company shall use its best efforts to obtain the withdrawal of
such order.

         The Selling  Stockholders,  upon receipt of any notice from the Company
of the happening of any event of the kind described in Section 5(d) hereof, will
immediately  discontinue  disposition of the Registrable  Common Stock until the
Selling  Stockholders'  receipt  of the  copies of the  supplemented  or amended
prospectus  contemplated  by  Section  5(d)  and  copies  of any  additional  or
supplemental  filings which are incorporated by reference in the prospectus,  or
until the Selling  Stockholders  are advised in writing  (the  "Advice")  by the
Company that the use of the  prospectus  may be resumed,  and, if so directed by
the  Company,  the Selling  Stockholders  will,  or will  request  the  managing
underwriter or  underwriters if any to, deliver to the Company (at the Company's
expense)  all  copies,  other than  permanent  file  copies  then in the Selling
Stockholders'  possession,  of the prospectus  covering such Registrable  Common
Stock  current at the time of receipt of such  notice.  In the event the Company
shall give any such notice,  the time periods mentioned in Section 5(b) shall be
extended by the number of days during the period from and  including the date of
the  giving  of  such  notice  to  and  including  the  date  when  the  Selling
Stockholders  shall have received (x) the copies of the  supplemented or amended
prospectus  contemplated  by  Section  5(d)  and  copies  of any  additional  or
supplemental  filings which are incorporated by reference in the prospectus,  or
(y) the Advice.

6.       Registration Expenses.
         ---------------------

         (a) The  Company  will  bear all  expenses  incident  to the  Company's
performance of or compliance with this Agreement, including, without limitation,
all  Commission and  securities  exchange or National  Association of Securities
Dealers, Inc. registration and filing fees, fees and expenses of compliance with

7.       Indemnification; Contribution.
         -----------------------------

         (a)  Indemnification  by the Company.  The Company agrees to indemnify,
protect and hold  harmless,  to the full extent  permitted  by law,  the Selling
Stockholders,  its officers, directors,  partners, employees and agents, and any
agent or  investment  adviser of any  thereof,  and each Person who controls any
such  Person  (within  the  meaning of the Act),  against  all  losses,  claims,
damages,  liabilities  and  expenses  arising  out of or based on any  untrue or
allegedly  untrue  statement  of material  fact  contained  in any  registration
statement,  prospectus or  preliminary  prospectus  or any amendment  thereof or
supplement  thereto or any  omission  or  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  under  which  they  were  made,  not
misleading,  or any  violation  by the Company of the Act or the Exchange Act or
securities act of any state or any rule or regulation  thereunder  applicable to
the  Company  and  relating  to action or  inaction  required  of the Company in
connection with the registration of Registrable  Common Stock hereunder,  except
to the extent, and only to the extent,  that the same are caused by or contained
in any  information  which any Selling  Stockholder  furnished in writing to the
Company  expressly  for use  therein  or by a Selling  Stockholder's  failure to
deliver to a  purchaser  of  securities  a copy of the  registration  statement,
prospectus or preliminary  prospectus or any  amendments  thereof or supplements
thereto at a time when such Selling  Stockholder is required by the Act to do so
after the Company has  furnished  such  Selling  Stockholder  with a  sufficient
number of copies of the same. In connection with an underwritten  offering,  the
Company will  indemnify,  protect and hold  harmless the  underwriters  thereof,
selling   brokers,   dealer   managers,   and  similar   securities   industries
professionals,  their officers, directors, employees, agents and each Person who
controls  any such Person  (within the meaning of the Act) to the same extent as
provided above with respect to the indemnification of the Selling Stockholders.

         (b) Indemnification by the Selling Stockholders. In connection with any
registration  statement in which a Selling  Stockholder is  participating,  such
Selling  Stockholder  will  furnish to the  Company in  writing  such  customary
information with respect to such Selling  Stockholder as the Company  reasonably
requests for use in connection with any such registration statement,  prospectus
or  preliminary  prospectus or any amendment  thereof or supplement  thereto and
agrees to indemnify, to the extent permitted by law, the Company, its directors,
employees,  agents,  officers,  and each Person who controls the Company (within
the meaning of the Act) against all losses,  claims,  damages,  liabilities  and
expenses  arising out of or based on any untrue or allegedly untrue statement of
a  material  fact  contained  in  any  registration  statement,   prospectus  or
preliminary  prospectus  or any amendment  thereof or supplement  thereto or any
omission or alleged  omission to state  therein a material  fact  required to be
stated therein or necessary to make the statements  therein, in the light of the
circumstances  under which they were made, not  misleading,  to the extent,  but
only to the  extent,  that such  untrue  statement  or  omission is caused by or
contained in any information which such Selling Stockholder furnished in writing
to the  Company  expressly  for use  therein  or by such  Selling  Stockholder's
failure to deliver  to a  purchaser  of  securities  a copy of the  registration
statement,  prospectus,  or preliminary  prospectus or any amendments thereof or
supplements  thereto at a time when such Selling  Stockholder is required by the
Act to do so after the Company has  furnished  such Selling  Stockholder  with a
sufficient number of copies of the same. In no event shall the liability of such
Selling Stockholder hereunder be greater in amount than the dollar amount of the
net  proceeds  received  by  such  Selling  Stockholder  upon  the  sale  of the
Registrable Common Stock giving rise to such indemnification obligation.

         (c)  Conduct of  Indemnification  Proceedings.  Any Person  entitled to
indemnification   hereunder   agrees  to  give  prompt  written  notice  to  the
indemnifying party after the receipt by such Person of any written notice of the
commencement of any action, suit,  proceeding or investigation or threat thereof
made in writing for which such Person will claim indemnification or contribution
pursuant  to this  Agreement,  but the  failure  to give such  notice  shall not
relieve the indemnifying party of its obligations hereunder except to the extent
the indemnifying party has been prejudiced as a consequence,  and, unless

                                      -10-
<PAGE>

in the reasonable  judgment of such indemnified party a conflict of interest may
exist between such indemnified party and the indemnifying  party with respect to
such claim,  permit the  indemnifying  party to assume the defense of such claim
with counsel reasonably  satisfactory to such indemnified party.  Whether or not
such defense is assumed by the indemnifying  party, the indemnifying  party will
not be subject to any liability for any settlement made without its consent (but
such consent will not be  unreasonably  withheld or  delayed).  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 in respect
of such claim or litigation.  If the  indemnifying  party is not entitled to, or
elects not to,  assume the defense of a claim,  it will not be  obligated to pay
the fees and  expenses  with  respect to such claim of more than one counsel for
the  indemnified  party with respect to which a claim has been  asserted  (which
fees and  expenses  will be paid as they are  billed to the  indemnified  party)
unless in the  reasonable  judgment  of such  indemnified  party a  conflict  of
interest  may  exist  between  such  indemnified  party  and any  other  of such
indemnified  parties with respect to such claim, in which event the indemnifying
party shall be obligated to pay the fees and expenses of such additional counsel
or counsels as shall be necessary to eliminate such conflicts in connection with
the representation of indemnified parties,  such fees and expenses to be paid as
they are billed to the indemnified party.

         (d)   Contribution.   In  order  to  provide  for  just  and  equitable
contribution in circumstances in which the indemnification  provided for in this
Section 7 is for any reason  held to be  unenforceable  although  applicable  in
accordance  with its terms,  the  Company and the  Selling  Stockholders,  shall
contribute to the losses,  claims,  damages,  liabilities and expenses described
herein,  in such  proportions so that the portion  thereof for which any Selling
Stockholder shall be responsible shall be limited to the portion determined by a
court or the  parties  to any  settlement  to arise out of or to be based on any
untrue  statement  of  material  fact  contained  in a  registration  statement,
prospectus,  or preliminary  prospectus,  or any amendment thereof or supplement
thereto or any omission to state  therein a material  fact required to be stated
therein  or  necessary  to make  the  statements  therein,  in the  light of the
circumstances under which they are made, not misleading,  caused by or contained
in any information  which such Selling  Stockholder  furnished in writing to the
Company  expressly for use therein or by such Selling  Stockholder's  failure to
deliver to a  purchaser  of  securities  a copy of the  registration  statement,
prospectus or preliminary prospectus or any amendments or supplements thereto at
a time when such Selling  Stockholder  is required by the Act to do so after the
Company has  furnished  such Selling  Stockholder  with a  sufficient  number of
copies  of the  same,  and the  Company  shall be  responsible  for the  balance
(subject  to any other  rights the Company  may have  against any other  selling
holder the  securities  of which were included in such  registration  statement,
preliminary prospectus, prospectus, amendment or supplement); provided, that the
liability of such Selling  Stockholder shall in no event exceed the net proceeds
from the  Registrable  Common Stock sold by it  thereunder.  The Company and the
Selling  Stockholder  agree  that it would  not be just and  equitable  if their
respective  obligations  to  contribute  were  to  be  determined  by  pro  rata
allocation, by reference to the proceeds realized by them or in any manner which
does not take  into  account  the  equitable  considerations  set  forth in this
Section 7(d).

8.       Rule 144 Sales.
         --------------

         The Company shall file the reports required to be filed by it under the
Exchange Act and the rules and regulations promulgated thereunder, and will take
such further action as any Stockholder may reasonably request, all to the extent
required from time to time to enable such Stockholder to sell Registrable Common
Stock (subject to Section  2(a)(ii)) without  registration  under the Act within
the  limitation of the  exemptions  provided by Rule 144,  provided that nothing
contained in this Section 8 shall require the Company to file or make  available
any reports or  information  that it is not  otherwise  required to file or make
available under the Exchange Act. Upon the written  request of any  Stockholder,

                                      -11-
<PAGE>

the Company shall deliver to such Stockholder a written  statement as to whether
it has complied with such requirements.

9.       Miscellaneous.
         -------------

         (a) Listing Application. If shares of Common Stock shall be listed on a
national  securities  exchange or NASDAQ,  the Company  shall,  at its  expense,
include in its listing  application  all of the shares of the Common  Stock then
owned by any Stockholder.

         (b)  Damages.  The  Company  recognizes  and agrees  that the holder of
Registrable  Common Stock shall not have an adequate remedy if the Company fails
to comply with the  provisions of this  Agreement,  and that damages will not be
readily  ascertainable,  and the Company  expressly  agrees that in the event of
such failure,  any holder of Registrable  Common Stock shall be entitled to seek
specific performance of the Company's obligations hereunder and that the Company
will not oppose an application seeking such specific performance.

         (c) Amendments and Waivers.  Except as otherwise  provided herein,  the
provisions of this Agreement may not be amended,  modified or supplemented,  and
waivers or consents to departures  from the  provisions  hereof may not be given
unless the Company has  consented  thereto  and the  Company  has  obtained  the
written  consent of the  Stockholders  holding  at least 70% of the  Registrable
Common Stock, provided that, without the consent of any other party, the Company
(i) may amend this Agreement to add as additional stockholder parties hereto any
(A) party to the Second Amended Agreement or the Subordinate  Agreement,  or (B)
person that  purchases  Series E Preferred  Stock  reasonably  acceptable  to TC
Carting III,  L.L.C,  and (ii) shall amend this  Agreement to add as  additional
stockholder  parties hereto any transferees in a Thayer  Permitted  Transfer (as
defined in that certain Second Amended and Restated Stockholders'  Agreement, of
even date  herewith,  between  the  Company  and  certain  holders of its equity
securities).

         (d)  Notices.  All notices  and other  communications  provided  for or
permitted  hereunder  shall be in writing  and shall be deemed to have been duly
given if delivered  personally  or sent by  telecopier,  registered or certified
mail  (return  receipt  requested),  postage  prepaid  to the  parties  at their
respective addresses as reflected in the Company's records. Notices sent by mail
shall be effective five days after mailing;  notices sent by telecopier shall be
effective when receipt is acknowledged; and notices sent by courier guaranteeing
next day  delivery  shall be  effective  on the next  business  day after timely
delivery to the courier.

         (e) Successors and Assigns.  This Agreement  shall inure to the benefit
of and be  binding  upon the  successors  and  assigns  of each of the  parties;
provided,  that, no Person,  other than the Stockholders,  who acquire shares of
Registrable Common Stock in a transaction Registered under the Securities Act or
effected  without  registration  pursuant to Rule 144 under the  Securities  Act
shall have any rights or be entitled to any benefit hereunder in respect of such
Registrable Common Stock.

         (f)  Counterparts.  This  Agreement  may be  executed  in any number of
counterparts
and by the  parties  hereto  in  separate  counterparts,  each of which  when so
executed shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement.

         (g) Headings.  The headings in this  Agreement are for  convenience  of
reference only and shall not limit or otherwise affect the meaning hereof.

         (h) Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

                                      -12-

         (i)  Severability.  In the event that any one or more of the provisions
contained  herein,  or the  application  thereof in any  circumstances,  is held
invalid,  illegal or unenforceable in any respect for any reason,  the validity,
legality and  enforceability of any such provision in every other respect and of
the  remaining  provisions  contained  herein  shall not be in any way  impaired
thereby,  it  being  intended  that  all of the  rights  and  privileges  of the
Stockholders shall be enforceable to the fullest extent permitted by law.

         (j) Entire Agreement.  This Agreement  constitutes the entire agreement
among the  parties,  and  supersedes  all prior  agreements  or  understandings,

respect to the Common Stock which is inconsistent with the rights granted to the
Stockholders  in this  Agreement  or  otherwise  conflicts  with the  provisions
hereof.

         (m) Enforcement. It is specifically agreed and understood that monetary
damages would not adequately compensate the non-breaching parties for the breach
of  this  Agreement  and  this  Agreement   shall   therefore  be   specifically
enforceable,  and any breach or threatened breach of this Agreement shall be the
proper  subject of a temporary or permanent  injunction  or  restraining  order,
without necessity of bond or other security.

         (n)  Government  Approvals.  Notwithstanding  anything to the  contrary
contained in this  Agreement,  the Company and any holder of Preferred  Stock or
Class B Stock,  as applicable,  shall use their best efforts to make any filings
with any  governmental  body, or obtain any approvals of any  governmental  body
(including those in connection with the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended from time to time (the "HSR Act"))  required prior to or
in connection  with any conversion of any such stock within a reasonable  period
of time. Any conversion  shall be delayed to the extent  necessary to allow such
filings to be made and such approvals to be obtained. In the event that any such
approvals  cannot be  obtained,  the  Company  shall not,  nor shall it have the
obligation  to,  convert any Preferred  Stock or Class B Stock into  Registrable
Common Stock.  The costs and expenses  (including  reasonable  attorneys'  fees)
associated with any filing or approval  required  (including those in connection
with the HSR Act) shall be paid by the Company.

         (o) Certain Additional Matters.  Following the date hereof, the Company
shall use its best efforts to (i) have each of its stockholders  that is a party
to the Second Amended Agreement or Subordinate Agreement that has not heretofore
become a party to this Agreement, execute a joinder agreement hereto in the form
of Exhibit A hereto,  and (ii) obtain the  signatures  of all persons  listed as
signatories to the Second  Amended and Restated  Registration  Rights  Agreement
substantially  in the  form  attached  hereto  as  Exhibit  B hereto  (the  "New
Registration  Rights  Agreement"),  it being understood and agreed that such New
Registration   Rights  Agreement  will  not  become  effective  until  all  such
signatures are obtained.  All rights granted to the stockholder  parties to this
Agreement  shall be, if  applicable,  subordinate  to the rights  granted to the
stockholder parties under the Second Amended Agreement.

         By execution  hereof  (including  by  execution of a joinder  agreement
hereto) the stockholder parties hereto agree to (i) subordinate their rights and
interests  under  Section  2 and  3(b) of the  Second

                                      -13-
<PAGE>

Amended  Agreement in an equitable  manner and to the extent  required such that
each stockholder party hereto have, to the extent possible and without breaching
the Second Amended  Agreement,  the  respective  rights which would have been in
effect if the New Registration  Rights Agreement had become effective,  and (ii)
extend to the other  stockholder  parties hereto,  if applicable,  the rights to
request  registrations under Section 2 of the Second Amended Agreement.  Nothing
in this  Agreement  shall act as waiver of any rights  under the Second  Amended
Agreement as between any party hereto and any stockholder not a party hereto.

         If at any time the Company obtains the signatures of all parties to the
New Registration  Rights  Agreement,  the Company shall cause the Second Amended
Agreement,  and the parties hereto shall cause this Agreement,  to be terminated
and the New  Registration  Rights Agreement shall become effective and supersede
this Agreement and the Second Amended Agreement.

         (p) Third Party  Beneficiaries.  Except as expressly  provided  herein,
nothing  contained  in this  Agreement is intended to confer on any person other
than the parties and their  respective  successors  and permitted  assigns,  any
rights,  remedies,  obligations  or  liabilities  under  or by  reason  of  this
Agreement.

         WHEREAS, the Company and certain of its stockholders (collectively, the
"Stockholders")  are parties to that certain  Amended and  Restated  Subordinate
Registration  Rights  dated as of October  10,  2003 (the  "Registration  Rights

         WHEREAS, the undersigned and the Company desire the New Party to become
a party to the Registration Rights Agreement;

         NOW,  THEREFORE,  in  consideration  of the  premises,  the  terms  and
provisions set forth herein, the mutual benefits to be gained by the performance
