Governmental  Authority,  or any agreement or instrument to which the Company or
any of its  Subsidiaries is a party or by which any of them is bound or to which

in accordance  with the terms of Purchased  Shares,  be duly and validly issued,
fully  paid and  nonassessable;  and the  Purchased  Shares  when  executed  and

            VALID OR EFFECTIVE UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED. A COPY
            OF THE  PREFERRED  STOCK  PURCHASE  AGREEMENT  IS ON FILE AND MAY BE
            INSPECTED  AT  THE  PRINCIPAL  EXECUTIVE  OFFICE  OF  THE  AFORESAID
            CORPORATION.  THE HOLDER OF THIS CERTIFICATE,  BY ACCEPTANCE OF THIS
            CERTIFICATE,  AGREES TO BE BOUND BY THE PROVISIONS OF SUCH PREFERRED
            STOCK PURCHASE AGREEMENT."

            4.05 Termination of Restrictions.  The restrictions  imposed by this
Section 4 upon the transferability of the Restricted  Securities shall cease and
terminate as to any particular Restricted Security when such Restricted Security
shall have been effectively  registered under the Securities Act and sold by the
Holder thereof in accordance  with such  registration or sold under and pursuant
to Rule 144 or is eligible to be sold  pursuant  to  paragraph  (k) of Rule 144.
Whenever the  restrictions  imposed by this Section 4 shall  terminate as to any
Restricted  Security as hereinabove  provided,  the Holder  thereof shall,  upon
written request, be entitled to receive from the Company, without expense, a new
certificate  evidencing  such  Restricted  Security not bearing the  restrictive
legend  otherwise  required  to  be  borne  by  a  certificate  evidencing  such
Restricted Security.

            Section 5. Additional Provisions Relating to Transfers.

            5.01  Disposition of Securities.  Subject to compliance  with all of
the provisions of Section 4 hereof,  any Holder shall have the right to transfer
any Restricted Securities to any Person.

            (a) Subject to compliance  with the  provisions of Section 4 hereof,
except with respect to the  requirement for an opinion of counsel to the Holder,
which shall not be required  under this Section  5.01(a),  any Holder shall have
the right to transfer any Restricted Securities:

                        (i) to any  Person  who at the time  owns  (directly  or
               indirectly)  at least a majority of the voting  capital  stock or
               other equity interests of such Holder; or

                        (ii) to any Person at least a majority  of whose  voting
               capital stock shall at the time be owned (directly or indirectly)
               by such Holder or by any Person who owns (directly or indirectly)
               at least a majority of the voting  capital  stock or other equity
               interests of such Holder.

            (b) In the event of any  underwritten  public offering of Restricted
Securities in which a Holder which is subject to the  provisions of Regulation Y
is  participating,  the Company shall use its  reasonable  efforts to assist the
underwriter  in ensuring  that any Purchased  Shares or

                                       17

<PAGE>

Underlying Common Stock issued by the Company and sold by such Holder are widely
disseminated.

            5.02  Repurchase  of Common  Stock.  The Company  shall give 30 days
prior written notice to each Holder before  purchasing,  redeeming,  retiring or
otherwise acquiring any shares of Common Stock of the Company.

            5.03 Transfer, Division and Combination. Subject to Sections 4 and 5
hereof,  transfer of Purchased Shares and all rights thereunder,  in whole or in
part (the "Transferred  Purchased  Share"),  shall be registered on the books of
the  Company  to  be  maintained  for  such  purpose,  upon  surrender  of  such
Transferred  Purchased  Shares at the office of the Company  maintained for such
purpose  pursuant to Section  11.03  hereof,  together  with a written  power or
assignment, duly executed by the relevant Holder and payment of funds sufficient
to pay any transfer  taxes payable upon the making of such  transfer.  Upon such
surrender and, if required, such payment, the Company shall, subject to Sections
4 and 5 hereof and the immediately  following sentence,  (a) execute and deliver
new  Preferred  Shares  in the  name of the  assignee  or  assignees  and in the
denominations  specified  in such  instrument  of  assignment,  (b) issue to the
assignor  new  Preferred  Shares  evidencing  the  portion  of such  Transferred
Purchased  Shares not so assigned or  transferred  and (c) promptly  cancel such
Transferred  Purchased  Shares.   Preferred  Shares,  if  properly  assigned  in
compliance  with  Sections 4 and 5 hereof,  may be  converted by an assignee for
shares  of  Common  Stock   without   having  new   Preferred   Shares   issued.
Notwithstanding  any provision herein to the contrary,  the Company shall not be
required to register  the  transfer of  Preferred  Shares or  Underlying  Common
Shares in the name of any Person who  acquired  such  Preferred  Shares (or part
thereof) or any Underlying  Common Stock  otherwise than in accordance with this
Agreement.

            The  Company  shall  maintain  with  its  transfer  agent  or at its
aforesaid  office,  books for the  registration  and  transfer of the  Preferred
Shares.

            Section  6.  Notice to  Holders  of  Preferred  Shares.  In case the
Company  shall  propose (a) to pay any dividend  (other than a regular  periodic
dividend  payable in cash out of earned  surplus)  to the  holders of its Common
Stock or to make any other  distribution  to the holders of its Common Stock, or
(b) to offer to the holders of its Common Stock  rights to  subscribe  for or to
purchase any Additional  Shares of Common Stock or Other  Securities,  rights or
options, or (c) to effect any reclassification of its Common Stock (other than a
reclassification involving only the subdivision,  or combination, of outstanding
shares of Common Stock), or (d) to effect any capital reorganization,  or (e) to
effect any  consolidation,  merger or share exchange in which the Company is not
the surviving  entity,  or is the surviving entity but its Common Stock shall be
changed into  securities or other property of another  Person,  or sale,  lease,
transfer or other  disposition  of all or a majority of its property,  assets or
business,  or (f) to effect the  liquidation,  dissolution  or winding up of the
Company,  then,  in each such case,  the Company  shall give to each Holder,  in
accordance with Section 11.02 hereof,  a notice of such proposed  action,  which
shall specify the date on which a record is to be taken for the purposes of such
stock dividend,  distribution  or offering of rights,  or the date on which such
reclassification,  reorganization,  consolidation, merger, share exchange, sale,
lease, transfer, disposition,  liquidation, dissolution or winding up is to take
place and the date of  participation  therein by the

                                       18

<PAGE>

holders  of Common  Stock,  if any such  date is to be fixed and shall  also set
forth such facts  with  respect  thereto  as shall be  reasonably  necessary  to
indicate the effect of such action on the Common  Stock,  if any, and the number
and kind of any other shares of stock which will comprise a Stock Unit,  and the
purchase price or prices thereof, after giving effect to any adjustment, if any,
which will be required as a result of such action. Such notice shall be so given
in the case of any  action  covered  by clause (a) or (b) above at least 20 days
prior to the  record  date for  determining  holders  of the  Common  Stock  for
purposes of such action,  and in the case of any other such action,  at least 20
days  prior to the date of the  taking  of such  proposed  action or the date of
participation  therein by the holders of Common  Stock,  whichever  shall be the
earlier.

            Section  7.  Reservation  and  Authorization  of Common  Stock.  The
Company  shall at all  times  reserve  and keep  available  for  issue  upon the
conversion of the Preferred  Shares such number of its  authorized  but unissued
shares of Common Stock as will be sufficient to permit the conversion in full of
all the  outstanding  Preferred  Shares from time to time.  All shares of Common
Stock which shall be so issuable,  when issued upon  conversion of any Preferred
Shares in accordance with the terms thereof, shall be duly and validly issued by
the Company, fully paid and nonassessable and free and clear of all Liens.

            The  Company  will  list  on  each  trading  market,  including  any
automated  quotation  system and any  securities  exchange,  on which any Common
Stock may at any time be listed or  admitted  to  trading,  subject to  official
notice of issuance upon  conversion of the Preferred  Shares,  and will maintain
such  listing of or  admission  to, all shares of Common Stock from time to time
issuable upon the conversion of the Preferred  Shares.  The Company will also so
list on such  trading  market,  and will  maintain  such  listing  of, any Other
Securities  if at the time any  securities  of the same class shall be listed on
such trading market by the Company.

            Section 8. Stock and Preferred Shares Transfer Books.

            The Company  shall not close its stock  transfer  books or Preferred
Shares  transfer  books for the purpose of  preventing or delaying the exercise,
conversion or transfer of any Preferred Shares.

            Section 9. Holders' Special Rights.

            9.01  Replacement  of  Instruments.  Upon  receipt by the Company of
evidence reasonably  satisfactory to it of the ownership of and the loss, theft,
destruction  or  mutilation of any  certificate  or  instrument  evidencing  any
Preferred Shares issued by the Company, and

            (a) in the  case of  loss,  theft or  destruction,  of an  indemnity
      reasonably  satisfactory to it, provided that, if the owner of the same is
      Purchaser,   its  own  agreement  of  indemnity  shall  be  deemed  to  be
      satisfactory,  or if the  owner of the same is a Holder  the  Company  may
      require a bond, or

            (b) in the  case  of  mutilation,  upon  surrender  or  cancellation
      thereof,

                                       19

<PAGE>

      the Company, at its expense, shall execute,  register and deliver, in lieu
      thereof, a new certificate or instrument for such Preferred Shares.

            9.02 Restrictions on Certain Action.

            (a) The  Company  shall not at any time enter into an  agreement  or
other instrument  limiting in any manner (other than in a de minimis manner) its
ability  to  perform  its  obligations  under  this  Agreement  or  making  such
performance or the issuance of shares of Common Stock upon the conversion of any
Preferred Shares issued by it a default under any such agreement or instrument.

            (b) So long as at least 50% of all of the Purchased Shares issued to
Purchaser hereunder shall remain outstanding, neither the Company nor any of its
Subsidiaries  shall (i) issue  any  Participating  Security  or  Options  for or
Convertible Securities convertible into a Participating Security, (ii) issue any
class of equity other than Common Stock  outstanding  on the date hereof and any
Preferred  Stock of the  Company or (iii) make or agree to make  payments to any
Person,  such as any  "phantom"  stock  payments,  where the  amount  thereof is
calculated  with  reference to fair market or equity value of the Company or any
of its Subsidiaries.

            9.03 Inspection  Rights.  As and when  requested,  the Company shall
provide to Purchaser or any  transferee  who is a Holder of more than 15% of the
total  outstanding  Preferred  Shares or the agents or  representatives  of such
holder  all  information  and/or  access to all  information  in  respect of the
Company and its  Subsidiaries as the Company provides to members of the Board at
the same time or times  and/or  subject  to the same  conditions  to which  such
information or access thereto is provided to such members of the Board.

            9.04 Board Attendance.  So long as Purchaser owns 50% or more of the
Purchased  Shares  or the  Underlying  Common  Stock,  one  representative  (the
"Representative")  appointed  by  Purchaser  shall be  entitled  to  attend  all
meetings of (i) the Board,  (ii) the board of directors of any Subsidiary of the
Company and (iii) any committee of (i) and (ii) above  provided,  however,  that
the  Representative  shall  not be  entitled  to vote at any such  meeting.  The
Company  shall  reimburse,  by Company  check mailed  within 30 Business Days of
receipt  by  the  Company  of  proper  documentation   thereof,  the  reasonable
out-of-pocket  expenses  incurred  by  the  Representative  in  connection  with
attendance at any meetings pursuant to this Section 9.04; provided, however, the
Representative shall not be entitled to reimbursement for first-class travel.

            Section 10. Registration.

            10.01 Notice.  (a) On and after the date of this  Agreement (i) upon
receipt of notice (a "Demand Notice") from the Majority Holders  requesting that
the  Company  effect  the  registration  of the  Preferred  Shares  or shares of
Underlying  Common  Stock held by any Holder or  Holders  or (ii)  whenever  the
Company otherwise  proposes to effect the registration of any Common Stock under
the  Securities  Act, the Company shall  promptly,  and in any event at least 20
days  prior  to  the  anticipated  filing  date  of  the  proposed  registration
statement,  give written  notice of such proposed  registration  to all Holders.
Each Holder that wishes to register its

                                       20

<PAGE>

Preferred Shares or shares of Underlying  Common Stock (each, a "Seller") shall,
within 15 days after  receipt of such  notice from the  Company,  deliver to the
Company  a notice  (a  "Seller  Notice")  stating  that  such  Seller  wishes to
participate in such offering and setting forth the number of Preferred Shares or
Underlying Common Stock, as the case may be, that such Seller desires to include
in such offering.  The Company  thereupon shall,  subject to Section 10.01(b) as
expeditiously as possible, use its best efforts to effect the registration under
the Securities Act of such Preferred Shares or Underlying Common Stock (any such
registration  effected or  undertaken  pursuant to a Demand  Notice being herein
referred to as a "Demand  Registration");  provided,  however,  that the Company
shall not be required to effect  more than (x) one Demand  Registration  on Form
S-1 or other  "long-form"  registration  as may be available  and (y) two Demand
Registrations  on  Form  S-3  or  other  "short-form"  registration  as  may  be
available;   provided,   further  that  the   Company's   obligation  to  effect
registration  of  Preferred  Shares or  Underlying  Common  Stock under  Section
10.01(a)(ii)  shall be unlimited in number.  In the event that (i) the amount of
securities  proposed to be sold by Sellers  pursuant to a Demand Notice shall be
reduced  pursuant to Section 10.02(a) hereof to an amount which is less than 75%
of the amount of securities  originally proposed to be sold by Sellers or if any
securities  of the Company  other than those  proposed to be sold by Sellers are
included  in such  Demand  Registration  on a pari  passu  basis  with  Seller's
securities,  or (ii) any  Demand  Notice  shall be  withdrawn  by the  Holder or
Holders  originally giving such Demand Notice at any time prior to the filing by
the Company of a  preliminary  registration  statement in  connection  with such
Demand Notice,  then, in such event, no right to a Demand  Registration shall be
deemed to have been  exercised  or  forfeited  and such Demand  Notice shall not
operate  to reduce  the  Company's  obligation  to effect  the  number of Demand
Registrations  pursuant to a Demand  Notice as specified in this Section  10.01;
provided,  however,  if the Demand  Notice is withdrawn by the Holder or Holders
originally giving such Demand Notice as provided in subparagraph (ii) above, the
right to a Demand  Registration  shall be deemed to have been  exercised if such
Holder or Holders does not  reimburse  the Company for all costs and expenses of
such withdrawn registration.

            (b)  Deferral  of Filing.  The Company may defer the filing (but not
the  preparation) of a registration  statement  required by Section  10.01(a)(i)
until a date not later than 60 days in the case of clause (i) below and,  in the
case of clause (ii) below, 180 days (or, if longer,  90 days after the effective
date of the registration statement contemplated by clause (ii) below), after the
date of the Demand  Notice if (i) at the time the  Company  receives  the Demand
Notice,  the  Company or any of its  Subsidiaries  is  engaged  in  confidential
negotiations  or other  confidential  business  activities,  disclosure of which
would be required in such  registration  statement (but would not be required if
such  registration  statement were not filed),  and the Board determines in good
faith that such  disclosure  would be materially  detrimental to the Company and
its   shareholders  or  would  have  a  material  adverse  effect  on  any  such
confidential  negotiations or other confidential  business  activities,  or (ii)
prior to  receiving  the Demand  Notice,  the Board had  determined  to effect a
registered  underwritten  public  offering of the Company's  securities  for the
Company's account and the Company had taken  substantial  steps (including,  but
not  limited to,  selecting a managing  underwriter  for such  offering)  and is
proceeding with reasonable  diligence to effect such offering. A deferral of the
filing of a registration  statement  pursuant to this Section  10.01(b) shall be
lifted, and the requested registration  statement shall be filed forthwith,  if,
in the case of a deferral pursuant to clause (i) of the preceding sentence,  the
negotiations or other activities are disclosed or terminated, or, in the

                                       21

<PAGE>

case of a  deferral  pursuant  to clause  (ii) of the  preceding  sentence,  the
proposed registration for the Company's account is abandoned.  In order to defer
the filing of a registration  statement  pursuant to this Section 10.01(b),  the
Company shall  promptly (but in any event within 10 days),  upon  determining to
seek such deferral,  deliver to each Seller a certificate signed by an executive
officer of the Company pursuant to this Section 10.01(b) and a general statement
of the reason for such deferral and an approximation  of the anticipated  delay.
Within 15 days after receiving such certificate,  Seller's holding a majority in
interest of the Underlying  Common Stock for which  registration  was previously
requested  may  withdraw  such  request  by  giving  notice to the  Company;  if
withdrawn,  the  Demand  Notice  shall be  deemed  not to have been made for all
purposes  of this  Agreement.  The Company may not invoke its right to defer the
filing of a registration statement under this Section 10.01(b) more than once in
any eighteen month period.

            (c) If the Majority  Holders so elect, the offering of the Preferred
Shares,  the Underlying  Common Stock and/or the Other Securities  pursuant to a
Demand  Registration  shall be in the form of an underwritten  offering.  If any
Demand  Registration  is in the form of an underwritten  offering,  the Majority
Holders will select and obtain the investment banker or investment  bankers that
will administer the offering;  provided,  that such  investment  banker shall be
reasonably satisfactory to the Company.

            10.02 Proration.

            (a) In the case of a Demand Registration, if the underwriter (or, if
the  offering  is not  underwritten,  an  independent  financial  advisor to the
Sellers) determines that marketing factors require a limitation on the number of
securities to be offered and sold, there shall be included in such  registration
only that number of securities that the underwriter,  or financial  advisor,  as
the case may be,  reasonably  believes  will not  jeopardize  the success of the
offering. Any reduction in the number of securities to be so offered shall first
be  pro-rata  among all  Persons  (other  than the  Company)  proposing  to sell
securities pursuant to such offering who are not Sellers, based on the number of
securities  originally  proposed  to be  sold  by each of  them,  and  then,  if
necessary,  pro-rata  among all Sellers  and the Company  based on the number of
securities originally proposed to be sold by each of them.

            (b) In the case of a registration to be effected pursuant to Section
10.01(a)(ii)   hereof,   if  the  underwriter   (or,  if  the  offering  is  not
underwritten,  an independent  financial advisor to the Company) determines that
marketing factors require a limitation on the number of securities to be offered
and sold in the offering,  including securities requested to be offered and sold
by  Sellers,  there  shall be  included  in the  offering  only  that  number of
securities  that the  underwriter,  or  financial  advisor,  as the case may be,
reasonably  believes  will not  jeopardize  the  success  of the  offering.  Any
reduction in the number of securities  to be so offered shall be pro-rata  among
the  Shareholders,  the  Sellers  and  all  other  Persons,  proposing  to  sell
securities  pursuant  to  such  offering,  based  on the  number  of  securities
originally proposed to be sold by each such Person.

Nothing  contained  herein shall be construed to limit in any way the  Company's
right, in its sole  discretion,  to withdraw any  registration  statement (other
than a  registration  statement  filed

                                       22

<PAGE>

pursuant  to  a  Demand  Notice)  before  such  registration  statement  becomes
effective,  or to postpone the offering of securities  contemplated  by any such
registration statement.

            10.03  Registration  Procedures.  If and  whenever  the  Company  is
required by the  provisions  of Section  10.01(a)(i)  hereof or, with respect to
subsections  (iii),  (vi), (vii),  (viii),  (ix), (x) and (xiii) of this Section
10.03, by the provisions of Sections 10.01(a)(i) or (ii) hereof, to use its best
efforts to effect the registration of any of its securities under the Securities
Act, the Company shall, as expeditiously as possible,

               (i) prepare and file with the Commission a registration statement
            on Form S-1 (or such other  "long-form")  or Form S-3 (or such other
            "short-form") as may be available,  as the case may be, with respect
            to  such   securities  and  use  its  best  efforts  to  cause  such
            registration  statement to become and remain  effective for a period
            of not less than 90 days to permit  the sale of such  securities  in
            accordance  with the plan of  distribution  chosen by the  Seller or
            Sellers and the underwriter;

               (ii) prepare and file with the  Commission  such  amendments  and
            supplements to such  registration  statement and the prospectus used
            in   connection   therewith   as  may  be  necessary  to  keep  such
            registration  statement  effective and to comply with the provisions
            of the Securities Act with respect to the sale or other  disposition
            of all securities covered by such registration statement;

               (iii)  furnish  to  each  Seller  such  numbers  of  copies  of a
            prospectus,  including a preliminary prospectus,  in conformity with
            the requirements of the Securities Act, and such other documents, as
            such Seller may reasonably request in order to facilitate the public
            sale or other disposition of the securities owned by such Seller;

               (iv) use its best  efforts to register or qualify the  securities
            covered by such  registration  statement under such other securities
            or blue sky laws of such  jurisdictions  within the United States as
            each Seller shall reasonably  request,  and do such other reasonable
            acts and things as may be  requested  of it to enable such Seller to
            consummate   the   public   sale  or  other   disposition   in  such
            jurisdictions  of the securities  owned by such Seller,  except that
            the Company shall not for any such purpose be required to qualify to
            do business as a foreign corporation in any jurisdiction  wherein it
            is not so qualified;

               (v) use its best efforts to cause the securities  covered by such
            registration  statement  to be  registered  with or approved by such
            other U.S. or state  governmental  agencies or authorities as may be
            necessary to enable the Seller or Sellers  thereof to consummate the
            disposition of such securities;

               (vi)  notify  each  Seller  of any  securities  covered  by  such
            registration  statement,  at any  time  when a  prospectus  relating
            thereto is required to be delivered under the Securities Act, of the
            Company's  becoming  aware  that  the  prospectus  included  in such
            registration  statement,  as  then in  effect,  includes  an  untrue
            statement  of a material  fact or omits to state any  material  fact
            required to be stated  therein or necessary  to make the

                                       23

<PAGE>

            statements  therein not misleading in the light of the circumstances
            then existing (upon receipt of which each Seller agrees to forthwith
            cease making  offers and sales of such  securities  pursuant to such
            prospectus  and to  deliver  to  the  Company  any  copies  of  such
            prospectus  then  in the  possession  of  such  Seller),  and at the
            request of any such  Seller  promptly  prepare  and  furnish to such
            Seller a reasonable number of copies of a prospectus supplemented or
            amended so that, as thereafter  delivered to the  purchasers of such
            securities, such prospectus shall not include an untrue statement of
            a material  fact or omit to state a  material  fact  required  to be
            stated  therein or  necessary  to make the  statements  therein  not
            misleading in the light of the circumstances then existing;

               (vii)  make  available  to  its  security  holders,  as  soon  as
            reasonably practicable, an earnings statement covering the period of
            at least twelve months, but not more than eighteen months, beginning
            with one of the first three months after the  effective  date of the
            registration  statement,  which earnings statement shall satisfy the
            provisions of Section 11(a) of the Securities Act;

               (viii)  otherwise  use  its  best  efforts  to  comply  with  all
            applicable rules and regulations of the Commission;

               (ix) use its best  efforts to list such  securities  on automatic
            quotation  system or any  securities  exchange  on which the  Common
            Stock of the  Company is then  listed,  or, if not so  listed,  on a
            national securities  exchange,  if the listing of such securities is
            then permitted under the rules of such exchange;

               (x) provide a transfer agent and registrar for all the securities
            covered by such registration  statement not later than the effective
            date of such registration statement;

               (xi)  enter  into  such  agreements  (including  an  underwriting
            agreement in customary form containing without limitation  customary
            indemnity  and  contribution  provisions  for  the  benefit  of  the
            underwriter or underwriters and the Seller or Sellers) and take such
            other actions as the Seller or Sellers shall  reasonably  request in
            order to expedite or facilitate the disposition of such securities;

               (xii)  obtain an opinion from the  Company's  counsel and a "cold
            comfort" letter from the Company's independent public accountants in
            customary  form and  covering  such matters as the Seller or Sellers
            shall reasonably request;

               (xiii) make  available for inspection by any Seller of securities
            covered  by  such   registration   statement,   by  any  underwriter
            participating  in any  disposition  to be effected  pursuant to such
            registration  statement  and by any  attorney,  accountant  or other
            agent  retained  by any such  Seller  or any such  underwriter,  all
            pertinent financial and other records, pertinent corporate documents
            and  properties  of the  Company,  and  cause  all of the  Company's
            officers,   directors  and  employees  to  supply  all   information
            reasonably  requested  by any such  Seller,  underwriter,  attorney,
            accountant or agent in connection with such registration  statement;
            and

                                       24

<PAGE>

               (xiv)   permit   any  Seller  of   securities   covered  by  such
            registration statement to require the insertion therein of material,
            furnished  to the  Company  in  writing,  which  in  the  reasonable
            judgment of such Seller should be included.

If any such registration or comparable statement refers to any Seller by name or
otherwise as the holder of any securities of the Company, then such Seller shall
have the right to require (A) the  insertion  therein of  language,  in form and
substance  satisfactory  to such Seller,  to the effect that the holding by such
Seller of such  securities  is not to be construed as a  recommendation  by such
Seller of the investment quality of the Company's securities covered thereby and
that such  holding  does not imply that such  Seller  will assist in meeting any
future  financial  requirements  of the  Company,  or (B) in the event that such
reference to such Seller by name or otherwise is not required by the  Securities
Act, the deletion of the reference to such Seller.

            The Company may require each Holder of securities  to, and each such
Holder,  as a condition to including  securities  in such  registration,  shall,
furnish the Company with such  information and affidavits  regarding such holder
and the  distribution  of such  securities  as the Company may from time to time
reasonably  request in writing in connection with such  registration.  No Seller
may participate in any  underwritten  registration  hereunder unless such Seller
(a)  agrees to sell  such  Seller's  securities  on the  basis  provided  in any
underwriting  arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all  questionnaires,  powers of
attorney,  indemnities,  lock-ups,  underwriting  agreements and other documents
reasonably required under the terms of such underwriting  arrangements and these
registration rights.

            Each Seller of  securities  agrees  that upon  receipt of any notice
from the Company of the happening of any event of the kind  described in Section
10.03(vi),  such Seller will forthwith  discontinue such Seller's disposition of
securities  pursuant to the registration  statement  relating to such securities
until  such  Seller's  receipt  of the  copies of the  supplemented  or  amended
prospectus contemplated by Section 10.03(vi) and, if so directed by the Company,
will deliver to the Company (at the  Company's  expense) all copies,  other than
permanent  file  copies,  then in such  Seller's  possession  of any  prospectus
relating to such securities at the time of receipt of such notice.

            10.04  Holdback on Sales.  The Company and the Holders  hereby agree
not to effect any public sale or distribution of any securities similar to those
registered  in  accordance  with Section  10.03 hereof  during the 14 day period
prior to, and during the 45 day period  beginning on, the effective  date of any
registration statement (except as part of such registration statement).

            10.05 Expenses.  Subject to Section 10.01,  all reasonable  expenses
incurred in complying  with this Section,  including,  without  limitation,  all
registration  and filing fees,  printing  expenses,  fees and  disbursements  of
counsel for the Company,  the reasonable fees and  disbursements  of one counsel
for the  Seller or the  Sellers  (to be chosen by the  Seller or by the  Sellers
holding a majority of the securities to be included by Sellers in a registration
statement),  expenses of any special audits  incident to or required by any such
registration  and expenses of complying  with the securities or blue sky laws of
any jurisdictions  (provided,  however,  the

                                       25

<PAGE>

Company  may delay  such  registration  for up to 30 days,  if such  delay  will
eliminate  the need  for  such  special  audit),  shall be paid by the  Company;
provided, that in no event shall the Company be required to pay any underwriting
discounts,  commissions or fees  attributable to the sale of shares of Preferred
Stock by a Seller hereunder.

            10.06 Indemnification.

            (a) In the event of any  registration of any of its securities under
the Securities  Act pursuant to this Section 10, the Company  shall,  and hereby
agrees to,  indemnify  and hold  harmless  each Seller of such  securities,  its
directors and officers,  partners,  and each other Person,  if any, who controls
such Seller within the meaning of Section 15 of the Securities Act,  against any
losses to which such Seller or any such director, officer, partner or Person may
become  subject under the  Securities Act or any other statute or at common law,
insofar as such losses (or actions in respect thereof) arise out of or are based
upon  any  alleged  untrue  statement  of any  material  fact  contained  in any
registration  statement under which such  securities  were registered  under the
Securities  Act, any  preliminary  prospectus or final  prospectus  with respect
thereto,  or any amendment or  supplement  thereto,  or any alleged  omission to
state therein a material fact required to be stated therein or necessary to make
the statements  therein not misleading,  and shall reimburse such Seller or such
director, officer, partner or participating Person or controlling Person for any
legal or any other expenses reasonably incurred by such Seller or such director,
officer,  partner or  participating  Person or controlling  Person in connection
with  investigating  or defending  any such loss;  provided,  however,  that the
Company  shall not be liable in any such case to the  extent  that any such loss
arises out of or is based upon any alleged untrue  statement or alleged omission
made in such registration  statement,  preliminary  prospectus,  prospectus,  or
amendment  or  supplement  in  reliance  upon  and in  conformity  with  written
information furnished to the Company for inclusion therein through an instrument
duly executed by such Seller; provided further, however that with respect to any
untrue statement or omission or alleged untrue statement or omission made in any
preliminary  prospectus,  the indemnity  agreement  contained in this  paragraph
shall not apply to the extent that any such loss,  claim,  damage,  liability or
expense results from the fact that a current copy of the prospectus was not sent
or given to the Person  asserting  any such loss,  claim,  damage,  liability or
expense at or prior to the written  confirmation  of the sale of the  securities
concerned to such Person if the Company had prior  thereto given such Seller the
notice  referred to in Section  10.03(vi)  hereof and  provided to such Seller a
supplemented or amended  prospectus as contemplated  by Section  10.03(vi),  and
such current copy of the  prospectus  would have cured the defect giving rise to
such loss, claim, damage,  liability or expense.  Such indemnity shall remain in
full force and effect  regardless of any  investigation  made by or on behalf of
such Seller or such  director,  officer or  participating  Person or controlling
Person, and shall survive the transfer of such securities by such Seller.

            (b) Each Seller of securities  which are included in a  registration
statement hereunder, as a condition to including securities in such registration
statement,  shall,  to the full  extent  permitted  by law,  indemnify  and hold
harmless the Company,  its directors and officers and each other Person, if any,
who controls the Company within the meaning of Section 15 of the Securities Act,
against any losses to which the Company or any such director,  officer or Person
may become subject under the Securities Act or otherwise, insofar as such losses
(or  actions  in  respect  thereof)  arise out of or are based  upon any  untrue
statement or alleged  untrue

                                       26

<PAGE>

statement of any material fact  contained in such  registration  statement,  any
preliminary  prospectus,   final  prospectus  or  summary  prospectus  contained
therein,  or any  amendment 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 case of a prospectus,  in the
light of the circumstances  under which they were made) not misleading,  if such
untrue statement or alleged untrue statement or omission or alleged omission was
made in reliance upon and in conformity  with written  information  furnished to
the  Company by such Seller  specifically  for use in the  preparation  thereof;
provided, however, that if the obligation to provide indemnification pursuant to
this Section  10.06(b) is  applicable in more than one Seller,  such  obligation
shall be several, and not joint and several,  among such Sellers on the basis of
the number of securities included by each in such registration statement and the
aggregate  amount which may be recovered from any holder of securities  pursuant
to the indemnification  provided for in this Section 10.06(b) in connection with
any sale of securities  shall be limited to the total proceeds  received by such
holder from the sale of such  securities.  Such  indemnity  shall remain in full
force and effect  regardless  of any  investigation  made by or on behalf of the
Company  or any such  other  Person  and  shall  survive  the  transfer  of such
securities by such Seller.

            (c)  Promptly  after  receipt  by any Person  under this  Section of
notice of the commencement of any action,  such Person (an "Indemnified  Party")
shall,  if a claim in respect thereof is to be made against any other Person (an
"Indemnifying Party") for indemnity under this Section,  notify the Indemnifying
Party in writing of the commencement  thereof; but the omission so to notify the
Indemnifying  Party shall not relieve it from any liability which it may have to
any  Indemnified  Party,  except to the extent  that the  Indemnifying  Party is
prejudiced  thereby.  The  Indemnifying  Party may, upon being  notified of such
action,   assume  the  defense  thereof,   with  counsel  satisfactory  to  such
Indemnified Party, and, after such assumption,  the Indemnifying Party shall not
be liable to such Indemnified Party under this Section for any legal expenses of
other counsel or any other expenses,  in each case subsequently incurred by such
Indemnified  Party, in connection with the defense thereof;  provided,  however,
that the Indemnifying  Party may not assume the defense of the action, and shall
remain  liable to the  Indemnified  Party for its legal  expenses of counsel and
other  expenses,  in the event that the  Indemnified  Party has been  advised in
writing by counsel who, in good faith determines that a conflict of interest may
exist between the Indemnified Party and the Indemnifying Party.

            (d)  If  the  indemnification   provided  for  in  this  Section  is
unenforceable   although   available,   or  insufficient  to  hold  harmless  an
Indemnified  Party  hereunder for any losses (or actions in respect  thereof) in
respect of which the  provisions  of Sections  10.06(a)  or (b) would  otherwise
apply by their terms, then the Indemnifying Party shall contribute to the amount
paid or payable by such Indemnified Party as a result of such losses (or actions
in respect thereof) in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party on the one hand and the Indemnified Party on the
other hand in connection with the statements or omissions which resulted in such
losses (or actions in respect thereof),  as well as any other relevant equitable
considerations.  The relative  fault shall be  determined by reference to, among
other things,  whether the untrue or alleged untrue statement of a material fact
relates to  information  supplied by the  Indemnifying  Party on the one hand or
such  Indemnified  Party on the other  hand and the  parties'  relative  intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
statement or omission. The parties agree that it would not be just and equitable
if  contribution  pursuant  to  this  subsection  were  determined  by pro  rata
allocation or by any other

                                       27

<PAGE>

method of allocation which does not take account of the equitable considerations
referred  to in this  subsection.  The amount paid or payable as a result of the
losses (or  actions in respect  thereof)  referred  to above in this  subsection
shall be deemed to include any legal or other  expenses  reasonably  incurred by
such  Indemnified  Party in connection with  investigating or defending any such
action or claim.  In no event shall any Seller be required to  contribute in the
aggregate an amount exceeding the amount of proceeds  received by such Seller in
connection with any offering.  No Person guilty of fraudulent  misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution   from  any  Person   who  was  not   guilty  of  such   fraudulent
misrepresentation.

            10.07 No Other Registration  Rights. The Company shall not grant any
registration  rights to any holder of  securities  of the  Company in respect of
such securities if such  registration  rights would rank senior to, or otherwise
adversely affect in any material  respect,  the  registration  rights granted in
this Section 10.

            10.08 Rule 144. The Company  covenants that it will file the reports
required to be filed by it under the Securities Act and the Exchange Act so long
as the Company is  registered  under the Exchange  Act.  Upon the request of any
Holders,  the  Company  will  deliver to such Holder a written  statement  as to
whether it has complied with such requirements.

            Section 11. Miscellaneous.

            11.01  Waiver.  No failure on the part of any Holder to exercise and
no delay in  exercising,  and no course of dealing  with  respect to, any right,
power or privilege under this Agreement  shall operate as a waiver thereof,  nor
shall any single or partial exercise of any right, power or privilege under this
Agreement  preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The remedies provided herein are cumulative and
not exclusive of any remedies provided by law.

            11.02  Notices.  All notices and other  communications  provided for
herein  and  the  Preferred   Shares   (including,   without   limitation,   any
modifications  of, or waivers or consents under,  this Agreement) shall be given
or made in writing (including,  without limitation,  by telecopy), if to (a) any
party hereto,  delivered to the intended  recipient at the "Address for Notices"
specified below its name on the signature pages hereof;  or, as to any party, at
such other address as shall be  designated by such party in a written  notice to
each other party,  or (b) any other Person who is the  registered  Holder of any
Preferred  Shares or Underlying  Common Stock, to the address for such Holder as
it appears in the stock or Preferred  Shares  ledger of the  Company.  Except as
otherwise provided in this Agreement, all such communications shall be deemed to
have been duly given when transmitted by telecopier or personally delivered, or,
in the case of a mailed notice, upon receipt, in each case given or addressed as
aforesaid. The Company agrees to deliver to each Holder in the manner prescribed
by this  Section  11.02 any  notices or other  communications  delivered  to the
Shareholders.

            11.03 Office of the Company.  So long as any of the Preferred Shares
remain  outstanding,  the Company  shall  maintain an office in the  continental
United  States of  America  where the  Preferred  Shares  may be  presented  for
conversion,  transfer,  division or combination  provided in the  Certificate of
Designations.  Such office  shall be at 2800  Southeast  Market  Place,

                                       28

the  issuance  of  the  Preferred   Shares  hereunder  and  (y)  any  amendment,

in connection  with any  modification  of this  Agreement or the  Certificate of
Designations and shall hold each Holder harmless  without  limitation as to time
against any and all liabilities  with respect to all such taxes. The obligations
of the  Company  under this  Section  11.04(b)  shall  survive  any  redemption,
repurchase  or  acquisition  of the  Preferred  Shares  by the  Company  and the
termination of this Agreement.

            (c) Transfer Taxes, Etc. The Company shall pay any and all expenses,

Common  Stock in a name other than that in which the relevant  Preferred  Shares
are is registered,  and no such issue or delivery shall be made unless and until
the Person  requesting such issue has paid to the Company the amount of any such
tax, or has established,  to the satisfaction of the Company,  that such tax has
been paid.

            11.05  Amendments,  Etc. Except as otherwise  expressly  provided in
this Agreement,  any provision of this Agreement may be amended or modified only
by an  instrument  in writing  signed by the Company and the Holders of at least

Holders of Restricted Preferred Shares shall not be required with respect to any
