rights under the Pesa Agreement to acquire 17,648,839 shares of Common Stock.

     The Closing, as contemplated by the Pesa Agreement and there Sepa

cause to be voted all of the shares of Common Stock of which such party is the
beneficial owner in favor of the actions contemplated by (i), (ii), and (iii)
above. While the provisions of the Shareholders Agreement create an obligation
upon CCACA and CCACB and the WP Group to vote in a certain manner, CCACA and
CCACB disclaim beneficial ownership of any shares of Common Stock held by the
WP Group.

     The Registration Rights Agreement (filed under Item 7 as Exhibit C) expired

                                    AGREEMENT

          THIS AGREEMENT (the "Agreement") is being made this 25th day of July,
1995, by and among Alfred O.P. Leubert, Ltd. ("Leubert"), a New York
Corporation, and CC Acquisition Company A, L.L.C., a Delaware limited liability
company ("CCACA").

                              W I T N E S S E T H :

          WHEREAS, Leubert acquired from Sepa Technologies Ltd., Co. ("Sepa")
300,000 shares (the "Shares") of common stock, par value $.01 per share (the
"Common Stock"), of Chyron Corporation (the "Company"), a New York corporation;

          WHEREAS, the Shares were subject to a right of first refusal of CCACA
pursuant to the stock purchase agreement dated May 25, 1995 by and among Sepa,
John Servizio and CCACA; and

          WHEREAS, Leubert has acquired the Shares subject to such right of
first refusal and Leubert wishes to grant CCACA a similar right of first refusal
with respect to the Shares, subject to the terms and conditions set forth below.

          NOW, THEREFORE, in consideration of the premises, representations,
warranties, and covenants contained herein, and intending to be legally bound
hereby, the parties hereto agree as follows:

     1.   RIGHT OF FIRST REFUSAL.  (a) Leubert hereby grants to CCACA a right of
first refusal to acquire the Shares.  Leubert shall not sell or otherwise
dispose of the Shares except (x) to an Affiliate (as defined in Section 1.(b)
hereof), or (y) in compliance with the provisions set forth below:

               (i)       If Leubert proposes to dispose of the Shares to a non-
                         Affiliated third party, it shall deliver a notice (the
                         "Sale Notice") signed by him to
<PAGE>

                         CCACA relating to the proposed disposition; provided,
                         however, that no Sale Notice of any proposed
                         disposition of the Shares shall be valid unless Leubert
                         shall have received prior to the date of the Sale
                         Notice an offer therefor in writing from a BONA FIDE
                         purchaser stating the price, terms, and conditions of
                         the proposed sale.  The Sale Notice shall specify the
                         number of Shares (the "Offered Shares") that Leubert
                         intends to dispose of, identify and give the address of
                         the person to whom Leubert proposes to dispose the
                         Offered Shares, and indicate the price, terms, and
                         conditions of the proposed disposition.

               (ii)      CCACA shall have the irrevocable and exclusive option,
                         but not the obligation, to purchase from Leubert the
                         Offered Shares at the price and upon the terms and
                         conditions equal to those offered by the prospective
                         purchaser.  If CCACA elects to purchase the Offered
                         Shares, it shall give written notice of such election
                         within 30 days after the receipt of the Sale Notice;
                         and the closing regarding such Offered Shares shall
                         occur within 90 days after receipt of the Sale Notice.
                         Any transfer of the Offered Shares to CCACA shall
                         include the valid transfer of the registration rights
                         relating to such Offered Shares, subject to the terms
                         and conditions of the Registration Rights Agreement.

               (iii)     If Leubert gives a Sale Notice, and CCACA does not
                         elect to purchase the Offered Shares within such 30-day
                         period, Leubert may dispose of its Offered Shares to
                         the person or persons at the price, and on the terms
                         and conditions specified in the Sale Notice.


                                       -2-

          (b)  The term "Affiliate" of a person or entity or "Affiliated with" a
     specified person or entity means a person or entity that directly or
     indirectly, through one or more intermediaries, controls, is controlled by,
     or is under common control with the person or entity specified.  The term
     "control" means the possession, directly or indirectly, alone or in concert
     with others, of the power to direct or cause the direction of the
     management and policies of a person or entity, whether through ownership of
     securities, by contract, or otherwise.

          (c)  Notwithstanding Section 1.1(a)hereof, the Seller shall have the
     right to sell the Additional Shares pursuant to Rule 144 promulgated under
     the Securities Act of 1933, as amended; PROVIDED, however, that no such
     sales shall be made during the two-year period following the Closing.

     2.   SHARE OWNERSHIP.  Leubert represents that the Shares are owned by
Leubert free and clear of all liens, security interests, pledges, charges,
claims of creditors, encumbrances, stockholders' agreements, voting trusts, and
adverse claims of any kind or nature whatsoever.  Upon transfer to CCACA of the
Shares, Leubert will convey to the CCACA good title to the  Shares, free and
clear of all liens, security interests, pledges, charges, claims of creditors,
encumbrances, stockholders' agreements, voting trusts, and adverse claims of any
kind or nature whatsoever.

     3.   VOTING.  Leubert shall vote all shares of Common Stock of the Company
that it beneficially owns in accordance with the directions of CCACA.  In
furtherance of this purpose, Leubert shall deliver to CCACA, at the Closing,
Leubert's proxy relating to the voting of such Common Stock.

submits to the jurisdiction of the courts of the State of New York and of any
Federal court located in the State of New York in connection with any action or
proceeding arising out of or relating to this Agreement or of any document or

          (b)  Acquisition Company A hereby grants, conveys and assigns to the
     Assignees, in the amounts set forth opposite each Assignees' name in Column
     5 of Exhibit A-2 hereto, its right to acquire 5 million shares of the

     Acquisition Company A shall cause Pesa to deliver to the Assignees stock
     certificates representing such 5 million shares of Common Stock in the
     amounts set forth opposite such Assignee's name in Column 5 of Exhibit A
     hereto, duly endorsed or accompanied with stock powers duly endorsed for

<PAGE>

     Assignee's name in Column 6 of Exhibit A-2 hereto to Sepa by certified
     check or wire transfer in immediately available funds to an account in the
     United States designated by Sepa.

          (c)  Acquisition Company A hereby grants, conveys and assigns to the
     WP Group Assignees the right to participate in Acquisition Company A's
     exercise of its right of first refusal contained in Section 1.1(b) of the
     Sepa Agreement and in the Leubert Agreement as provided in this Section
     2.1(c).  Each time Sepa or Leubert delivers a Sale Notice, Acquisition
     Company A shall immediately (and in any event no later than two days after
     receipt thereof) deliver a copy of such Sale Notice to WPG Corporate
     Development Associates IV, L.P., as representative of the WP Group
     Assignees (the "Representative").  Acquisition Company A shall notify the
     Representative in writing within five (5) days of the receipt of such Sale
     Notice whether it intends to exercise its right of first refusal with
     respect to the Offered Shares and the Representative shall immediately (and
     in any event no later than two days after receipt thereof) deliver to the
     Assignees a copy of such notice delivered by Acquisition Company A to the
     Representative together with a copy of the Sale Notice previously delivered
     to the Representative.  If Acquisition Company A shall desire to exercise
     its right of first refusal, each of the WP Group Assignees shall have the
     irrevocable and exclusive option, but not the obligation, to purchase from
     Sepa or Leubert, as the case may be sixty percent (60%) of the Offered
     Shares at the price and upon the terms and conditions equal to those
     offered by the prospective purchaser in the proportions set forth opposite
     such WP Group Assignee's name in Column 10 of Exhibit A-2 hereto.  If
     Acquisition Company A shall not desire to exercise its right of first
     refusal, the WP Group Assignees shall have the irrevocable and exclusive
     option, but not the obligation, to purchase all of the Offered Shares at
     the price and upon conditions equal to those offered by


                                       -5-
<PAGE>

     the prospective purchaser in the proportions set forth opposite such WP
     Group Assignee's name in Column 10 of Exhibit A-2 hereto.  Within ten (10)
     days of receipt of the notices from the Representative each WP Group
     Assignee shall notify the Representative in writing whether it intends to
     exercise its right of first refusal with respect to its portion of the
     Offered Shares (including, if applicable, that portion of the Offered
     Shares that Acquisition Company A has stated it will not purchase).  To
     the extent any of the WP Group Assignees do not notify the Representative
     or states that such WP Group Assignee does not desire to exercise its right
     of first refusal (the "Non-Participating Assignees"), each of the other WP
     Group Assignees shall have the irrevocable and exclusive option, but not
     the obligation, to purchase the shares that could have been purchased by
     the Non-Participating Assignees in an amount equal to the product of
     (i) the Offered Shares such Assignee has a right to purchase divided by
     (ii) all of the Offered Shares, multiplied by the shares that the Non-
     Participating Assignees could have purchased.  The Representative shall
     notify Acquisition Company A and Pesa of the number of shares of Common
     Stock each participating WP Group Assignee will purchase no later than
     twenty-five (25) days after the Representative's receipt of the Sale
     Notice.  The Representative will coordinate with the WP Group Assignees
     regarding each WP Group Assignee's rights with respect to the right of
     first refusal.

          (d)  Acquisition Company B hereby grants, conveys and assigns to the
     Assignees, its right to acquire the number of shares of Common Stock set
     forth opposite such Assignee's name in Column 7 of Exhibit A-2 hereto,
     which aggregate to 17,648,839 shares of the Common Stock of the Company
     (representing sixty percent (60%) of 29,414,732 shares of the Common Stock
     of the Company) and each such Assignee hereby agrees to assume his or its
     obligation to pay as


                                       -6-
<PAGE>

     consideration for such shares, the amount set forth opposite each
     Assignee's name in Column 8 of Exhibit A-2 hereto, which aggregates to
     $8,471,442.83 (representing sixty percent (60%) of $14,119,071.36), in
     accordance with the terms and provisions set forth in Section 1.1(c) of the
     Pesa Agreement.

               (i)       At the Closing, the Assignors shall cause Pesa to
                         deliver to each Assignee stock certificates
                         representing the number of Installment Pesa Shares set
                         forth opposite each Assignee's name in Column 7 of
                         Exhibit A-2 hereto, duly endorsed or accompanied by
                         stock powers duly endorsed for transfer to each such
                         Assignee.  Such Installment Pesa Shares shall be
                         delivered to the Assignees free and clear of all liens,
                         security interests, pledges, charges, claims of
                         creditors, encumbrances, stockholders' agreements,
                         voting trusts, and adverse claims, of any kind or
                         nature whatsoever.

               (ii)      Each of the Assignees shall make payment for its
                         portion of the Installment Pesa Shares in the amount
                         set forth opposite each Assignee's name in Column 8 of
                         Exhibit A-2 hereto, by certified check or wire
                         transfer, in immediately available funds, to an account
                         in the United States designated by Pesa, in accordance
                         with the schedule set forth in Section 1.1(c)(ii) of
                         the Pesa Agreement.

               (iii)     As security for the payment obligation for the portion
                         of the Installment Pesa Shares purchased by each
                         Assignee, each Assignee shall pledge its Installment
                         Pesa Shares to Pesa and deliver such Installment Pesa
                         Shares to the Escrow Agent, duly endorsed in blank or
                         accompanied with stock


                                       -7-
<PAGE>

                         powers duly endorsed in blank by such persons to be
                         held as collateral; such Installment Pesa Shares shall
                         be delivered to the Escrow Agent by each Assignee free
                         and clear of all liens, security interests, pledges,
                         charges, claims of creditors, encumbrances,
                         stockholders' agreements, voting trusts, and adverse
                         claims of any kind or nature whatsoever, except for any
                         claims or liens resulting from the terms and provisions
                         of the Pesa Agreement and the shareholders agreement,
                         dated as of July 25, 1995  among certain of the
                         Assignees and the Assignors (the "Shareholders
                         Agreement").

               (iv)      If Acquisition Company B fails to make its pro rata
                         portion of any monthly payment when due as provided in
                         Section 1.1(c) of the Pesa Agreement or any of the
                         Assignees fails to make its monthly payment when due as
                         provided in section 1.1(c) of the Pesa Agreement, the
                         WP Group Assignees shall have the right to cure such
                         payment default within twenty (20) days after receipt
                         of written notice thereof from Pesa.  Upon receipt from
                         Pesa by the Representative of a written notice of a
                         payment default by Acquisition Company B or any of the
                         Assignees "The Cure Notice") the Representative shall
                         immediately (and in any event no later than two days
                         after the receipt thereof) deliver a copy of such
                         notice to the WP Group Assignees.  Within ten (10) days
                         of the date the Representative receives the Cure
                         Notice, each WP Group Assignee shall notify the
                         Representative in writing whether it intends to
                         participate, with respect to its portion in the cure of
                         any monthly payment that Acquisition


                                       -8-
<PAGE>

                         Company B, or any of the non WP Group Assignees has
                         failed to make and to receive shares of Common Stock
                         out of escrow in respect of the amount so paid.  A WP
                         Group Assignee who has failed to make its monthly
                         installment shall not be eligible to participate in a
                         cure.   Each participating WP Group Assignee shall have
                         the right to cure in an amount equal to the product of
                         (i) the monthly installment most recently paid by such
                         WP Group Assignee dived by (ii) the total installment
                         payment due for such month (excluding amounts paid or
                         owed by Acquisition Company B and any of the non WP
                         Group Assignees), multiplied by the dollar amount to be
                         cured.  The Representative shall notify Acquisition
                         Company B and Pesa of the dollar amount each
                         participating WP Group Assignee will pay in respect of
                         a cure no later than twenty (20) days after the
                         Representative's receipt of the Cure Notice.
                         Acquisition Company B shall have the right to cure any
                         payment default not cured by the WP Group Assignees.
                         The Representative will coordinate with the WP Group
                         Assignees regarding such Assignee's right to cure.  In
                         either such case the party which cures such payment
                         default shall be entitled to receive out of escrow the
                         portion of such Installment Pesa Shares covered by such
                         payment free and clear of all liens, security
                         interests, stockholders' agreement, voting trusts and
                         adverse claims of any kind or notice whatsoever, except
                         for the Shareholders Agreement.

<PAGE>

Assignees or any affiliate or controlling entities thereof for the execution,
delivery, or performance of this Agreement by any of the Assignees.

     Section 4.5    PURCHASES FOR INVESTMENT PURPOSES.

          Each Assignee is acquiring the Initial Pesa Shares, the Installment
Pesa Shares, and the Sepa Shares (collectively, the "Shares") for its own
account for investment purposes only and with no intention of offering,
distributing, or reselling the Shares or any part thereof in any transaction
that would be in violation of any Federal or State securities laws, without
prejudice, however, to any right of a Assignee to sell or otherwise dispose of
all or any part of the Shares under a registration under the Securities Act of
1933, as amended (the "Securities Act"), and other applicable State securities
laws or under an exemption from such registration available under the Securities
Act and other applicable State securities laws.  Each Assignee has not taken or
caused to be taken, and shall not take or cause to be taken, any action that
would cause the Assignees, the Assignors, the Company or any of their respective
affiliates to be deemed an underwriter, as defined in Section 2(11) of the
Securities Act.

     Section 4.6    SOPHISTICATED INVESTOR.

          (a)  Each Assignee is a sophisticated investor as such term is
     contemplated under the Securities Act of 1933, as amended.  Each Assignee
     recognizes that the Company emerged from bankruptcy on December 27, 1991
     and that the purchase of the Shares involves significant risks.  Each
     Assignee also recognizes that none of the proceeds from the purchase of the
     Shares shall accrue to the benefit of the Company, but shall instead accrue
     to the benefit of Pesa and Sepa, as the case may be.


                                      -13-
<PAGE>

          (b)  No Assignee is relying upon Assignor, Pesa or Sepa, as the case
     may be, the Company or any of their respective Affiliates, accountants,
     attorneys or financial advisors for advice with respect to whether the
     Assignee's acquisition of the Shares constitutes a legal investment for the
     Assignees or with respect to the tax or other legal consequences of such
     purchase.

     Section 4.7    RESTRICTED SECURITIES.

          (a)  Each Assignee understands and agrees that (i) the sale of the
     Shares has not been registered under the Securities Act or any State
     securities laws; and (ii) each Assignee shall not offer or sell the Shares
     except pursuant to registration under the Securities Act or an available
     exemption from registration under the Securities Act.

          (b)  Each Assignee agrees to the imprinting, so long as appropriate,
     of any certificates representing the Shares with a conspicuous legend in
     substantially the following form:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") OR UNDER ANY
          STATE SECURITIES LAWS.  THESE SECURITIES SHALL NOT BE SOLD OR
          OTHERWISE TRANSFERRED IN THE ABSENCE OF EITHER (1) AN EFFECTIVE
          REGISTRATION STATEMENT UNDER THE ACT AND ANY APPLICABLE STATE
          SECURITIES LAWS, OR (2) AN OPINION OF COUNSEL, AS MAY BE REASONABLY
          SATISFACTORY TO THE COMPANY, THAT THE PROPOSED SALE OR TRANSFER IS IN
          ACCORDANCE WITH AN AVAILABLE EXEMPTION FROM THE REGISTRATION
          REQUIREMENTS OF THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

V.   MISCELLANEOUS.

     Section 5.1    BROKERAGE FEES.

          If any person shall assert a claim to a fee, commission, or other
compensation on account of alleged employment as a broker or finder, in
connection with or as a result of any of the transactions contemplated by this
Agreement, the party purportedly engaging such broker or finder shall indemnify
and hold harmless the other parties against any and all Claims (as defined in
Section 8.1 of the Pesa Agreement), as and when incurred, arising out of, based
upon, or in connection with such Claim by such person, except to the extent that
it is determined in any suit, action, or proceeding that such other parties had
engaged such broker or finder.

          Section 5.2    FURTHER ACTIONS.

          At any time and from time to time, each party agrees, as its expense,
to take such actions and to execute and deliver such documents or instruments as
may be reasonably necessary to effectuate the purposes of this Agreement.

     Section 5.3    SUBMISSION TO JURISDICTION.

          Each of the parties hereto irrevocably submits to the jurisdiction of

relating to this Agreement or of any document or instrument delivered pursuant
to, in connection with, or simultaneously with this Agreement.

     Section 5.4    MERGER; MODIFICATION.

          This Agreement, the Shareholders Agreement and the exhibits attached

agreements concerning such subject matter, and may be modified only by a written
instrument duly executed by each party to be charged.  None of the parties
hereto or their affiliate has entered into any other agreement concerning the
Common Stock which is the subject matter hereof with any other party hereto or
any third party other than with respect to any agreement specifically referred
to herein.

assigned meanings, and the following capitalized terms shall have the meanings
ascribed to them below:

          "AFFILIATE" shall mean (i) in the case of any individual stockholder,
any Associate of such individual or (ii) in the case of any other Person, any

                                        2
<PAGE>

issued and outstanding shares of Common Stock, CCAC shall have the right to
nominate three members of the Board of Directors (the "CCAC DIRECTORS") and each
of the Parties agrees to vote or cause to be voted all the shares of Common

With respect to the three

<PAGE>

members of the Board of Directors other than the CCAC Directors and the New
Investor Group Directors (the "INDEPENDENT DIRECTORS"), neither CCAC nor the New
Investor Group shall nominate or vote the shares of Common Stock of which such
Party is the Beneficial Owner in favor of the election of any Independent
Director unless CCAC and the WP Group and WIT/Lion each agrees with such
nomination or each votes the shares of Common Stock of which such Party is the
Beneficial Owner in favor of such election and CCAC and the WP Group and
WIT/Lion each shall cause (to the extent permitted under applicable laws and to
the extent within such Party's control) the members of the Board of Directors
designated by it not to nominate or vote in favor of the election of any
Independent Director unless the members of the Board of Directors designated by
the other group agrees with such nomination or votes in favor of such election.

          (b)  It is CCAC's and the New Investor Group's understanding that as
of the date of this Agreement, three members of the Board of Directors will have
resigned from the Board of Directors and the four remaining members of the Board
of Directors will increase the size of the Board of Directors to nine and vote
for the election of two of the CCAC Directors and all of the New Investor Group
Directors.  CCAC and the New Investor Group each hereby agrees it shall promptly
take whatever action necessary to effect the intent of this Agreement,
including, without limitation, making a written request for the Secretary of the
Company to call a special meeting of the Stockholders to, if necessary, (i)
elect the CCAC Directors and the New Investor Group Directors, (ii) remove any
members of the Board of Directors who are not agreed to by CCAC and the New
Investor Group and (iii) elect Independent Directors.  At such meeting of
Stockholders, CCAC and the New Investor Group each hereby agree to vote all of
the shares of Common Stock owned or held of record by it to effect the intent of
the immediately preceding sentence and the intent of this Agreement.

          (c)  If either CCAC or the New Investor Group shall notify the other
of its desire to remove any director of the Company previously designated by it,
each of the other Parties, subject to applicable law and Section 2(e) below,
shall vote or cause to be voted all of the shares of Common Stock of which such
Party is the Beneficial Owner so as to remove such director.

          (d)  If any director previously designated by CCAC or the New Investor
Group ceases to serve on the Board of


                                        4
<PAGE>

Directors (whether by reason of death, resignation, removal or otherwise), the
party that designated such director shall be entitled to designate a successor
director to fill the vacancy created thereby and each of CCAC and the New
Investor Group shall, subject to applicable law, cause the directors designated
by it to vote for such person designated to fill such vacancy.

          (e)  Each of the Parties agrees to indemnify and hold harmless the
Company and each other Party from and against any and all losses, claims,
damages or liabilities (or actions in respect thereof) to which the Company and
the other Parties, as the case may be, may be subject, insofar as such losses,
claims, damages or liabilities arise out of or are based upon the removal, in
accordance with the specific provisions of this Section 2, of any director
previously designated by it pursuant to this Section 2, and shall reimburse the
Company and the other Parties, as the case may be, for any legal or other
expenses reasonably incurred by the Company and the other Parties, as the case
may be, in connection with investigating or defending any such loss, claim,
damage, liability or action.

          (f)  The Parties hereto hereby agree that any individual designated as
a director of the Company may be removed for Cause.  For purposes of this
Section 2.2(f), "Cause" shall mean the conviction of, or plea of NOLO CONTENDERE
to, a felony by such party, or commitment of fraud, embezzlement or theft by
such party against the Company, in each case as reasonably determined by a
majority vote of the Board of Directors.  No such removal of an individual
designated pursuant to this Section 2 shall affect any of the Parties' rights to
designate a different individual pursuant to this Section 2.

          3.   TRANSFERS.  (a) Notwithstanding any other provisions of this
Agreement, each Party shall be entitled from time to time, without the consent
of any other Parties or compliance with any of the procedures specified in
Section 5 hereof, to Transfer any or all of the shares of Common Stock owned by
it to any of its Affiliates, any other Party or any limited partner of any of
the general partnerships that is a Party or an Affiliate of a Party, so long as
such Permitted Transferee agrees in form and substance satisfactory to the
Parties, to be, and becomes, bound by the terms of this Agreement.


                                        5
<PAGE>

          (b)  Each Party agrees that it and its Affiliates will not Transfer
10% or more of the outstanding shares of Common Stock in one or a series of
transactions unless (i) such Transfer is in accordance with Section 3(a) hereof,
(ii) such Transfer is in compliance with the procedures specified in Section 5
hereof and such Permitted Transferee agrees in form and substance satisfactory
to the Parties, to be, and becomes, bound by the terms of this Agreement or
(iii) such Transfer is in connection with any offering of Common Stock (x)
pursuant to a registration statement filed with the Securities and Exchange
Commission, (y) pursuant to the volume and manner of sale limitations set forth
in Rule 144 under the Securities Act of 1933, as amended (the "ACT") or (z)
pursuant to Regulation S of the Act.

          4.   EFFECT OF VOID TRANSFERS.  In the event of any purported Transfer
of any shares of Common Stock in violation of the provisions of this Agreement,
such purported Transfer shall be void and of no effect.

          5.   TAG-ALONG RIGHTS.  (a)  Subject to Section 5(b) hereof, no later
than 20 days prior to the proposed date of consummation of a Transfer of any
shares of Common Stock, the transferring Party shall provide each other Party
with written notice of the proposed Transfer, including the Person to whom it
wishes to Transfer shares, the number of shares proposed to be Transferred, and
the price and other material terms and conditions of the proposed Transfer.
Each such other Party shall then have the right by notice given no later than 10
days following receipt of the 20-day notice referred to above, and the
transferring Party shall afford each such other Party the opportunity, to
include in such Transfer a pro rata portion of the shares of Common Stock held
by such other Party on the same terms and conditions.  The term "pro rata
portion" as used above shall be determined by multiplying the number of shares
of Common Stock owned by a Party at such time by a fraction, the numerator of
which is equal to the number of shares of Common Stock owned by such Party at
such time and the denominator of which is the number of shares of Common Stock
owned by all Parties at such time having elected to participate in such
Transfer.  If necessary, the party initially proposing the Transfer shall reduce
the number of its shares to be included in the Transfer to permit such pro rata
participation.  In the event any Party elects to sell less than its full pro
rata portion, the difference shall be allocated among each of the other Parties
having elected to participate in such Transfer and each such other Party shall


                                        6
<PAGE>

be entitled to include in such Transfer its pro rata portion (calculated
excluding such difference from the denominator of the fraction referred to
above) of such difference until no such difference remains.

          (b)  The Tag-Along Rights of the Parties shall not pertain or apply to
(a) any offering of Common Stock by the Parties or their transferees (i)
pursuant to a registration statement filed with the Securities and Exchange
Commission or any similar authority outside the United States, or (ii) pursuant
to the volume and manner of sale limitations set forth in Rule 144 under the
Securities Act of 1933, as amended, as in effect on the date thereof, (b)
pledges of Common Stock which create a mere security interest pursuant to a BONA
FIDE loan transaction, or to the acquisition (by virtue of the exercise of the
security interest created by such pledge in accordance with its terms) or
subsequent sale of such Common Stock by the pledgee, (c) (i) any transaction for
which neither the Transferring Party nor its Affiliates or Associates receives
any consideration, directly or indirectly or (ii) any Transfers permitted by the
terms of Section 3 hereof.

          6.   TERMINATION.  This Agreement shall terminate, and thereby become
null and void, on the earlier to occur of (i) the tenth anniversary of the date
hereof and (ii) the date that either CCAC or the New Investor Group cease to
Beneficially Own at least five percent of the issued and outstanding shares of
Common Stock, except with respect to Section 2(e), which shall survive
indefinitely.

          7.   REPRESENTATIONS AND WARRANTIES.  Each Party hereto represents and
warrants as follows:

          (a)  The Person executing and delivering this Agreement on behalf of
such Party is duly authorized to execute and deliver this Agreement on behalf of

material agreement or instrument to which such Party is a party or which is
binding on such Party or the assets of


                                        7

interest in, any of the assets of such Party.

          (c)  It has good and marketable title to any shares of Common Stock
held by it immediately prior to the date of this Agreement, free and clear of

          8.   MISCELLANEOUS.

          (a)  OTHER STOCKHOLDERS' AGREEMENTS.  None of the Parties hereto nor
any Permitted Transferees thereof have entered into or shall enter into any
stockholder agreement or arrangement of any kind with any Person with respect to
voting of the Common Stock or that is otherwise inconsistent with the provisions
of this Agreement.

          (b)  AMENDMENTS.  This Agreement may be amended only by a written

          WHEREAS, the Purchasers are purchasing 64,414,732 shares of the common

          split of the Shares.  For purposes of this Agreement, any Registrable

          effective registration statement, (x) such Registrable Stock is sold

          Stock.

               (i)  References in this Agreement to any rules, regulations or
          forms promulgated by the Commission shall include rules, regulations
          and forms succeeding to the functions thereof, whether or not bearing
          the same designation.

          2.   DEMAND REGISTRATION.

               (a)  At any time after January 25, 1996, any Requesting Holders
          may make a written request to the Company (specifying that it is being
          made pursuant to this Section 2) that the Company file a registration
          statement under the 1933 Act (or a similar document pursuant to any
          other statute then in effect corresponding to the 1933 Act) covering
          the registration of Registrable Stock.  In such event, the Company
          shall (x) within ten (10) days thereafter notify in writing all other
          Holders of Registrable Stock of such request, and (y) use its best
          efforts to cause to be registered under the 1933 Act all Registrable
          Stock that the Requesting Holders and such other Holders have, within
          twenty (20) days after the Company has given such notice, requested be
          registered.  Unless a majority in interest of the Holders requesting
          to participate in such registration shall consent in writing, no other
          party, including the Company (but excluding another Holder), shall be
          permitted to offer securities in connection with such registration;
          provided, however, that this limitation shall not restrict or limit
          any registrations or rights to participate in any registration
          provided under or contained in the Registration Rights Agreement by
          and between the Company and Pesa, dated December 27, 1991.

               (b)  If the Requesting Holders intend to distribute the
          Registrable Stock covered by their request by means of an underwritten
          offering, they shall so advise the Company as a part of their request
          pursuant to Section 2(a) above, and the Company shall include such
          information in the written notice referred to in clause (x) of Section
          2(a) above.  In such event, the Holder's right to include its
          Registrable Stock in such registration shall be conditioned upon such
          Holder's participation in such underwritten offering and the inclusion
          of such Holder's Registrable Stock in the underwritten offering to the
          extent provided in this Section 2.  All Holders proposing to
          distribute Registrable Stock through such underwritten offering shall
          enter into an underwriting agreement in customary form with the
          underwriter or underwriters.  Such underwriter or underwriters shall
          be selected by a majority in interest of the Requesting Holders and
          shall be approved by the Company, which approval shall not be
          unreasonably withheld; PROVIDED, that all of the representations and
          warranties by, and the other agreements on the


                                       -3-
<PAGE>

          part of, the Company to and for the benefit of such underwriters shall
          also be made to and for the benefit of such Holders and that any or
          all of the conditions precedent to the obligations of such
          underwriters under such underwriting agreement shall be conditions
          precedent to the obligations of such Holders; and PROVIDED FURTHER,
          that no Holder shall be required to make any representations or
          warranties to or agreements with the Company or the underwriters other
          than representations, warranties or agreements regarding such Holder,
          the Registrable Stock of such Holder and such Holder's intended method
          of distribution and any other representation required by law or
          reasonably required by the underwriter.

               (c)  Notwithstanding any other provision of this Section 2 to the
          contrary, if the managing underwriter of an underwritten offering of
          the Registrable Stock requested to be registered pursuant to this
          Section 2 advises the Requesting Holders in writing that in its
          opinion marketing factors require a limitation of the number of shares
          to be underwritten, the Requesting Holders shall so advise all Holders
          of Registrable Stock that would otherwise be underwritten pursuant
          hereto, and the number of shares of Registrable Stock that may be
          included in such underwritten offering shall be allocated among all
          such Holders, including the Requesting Holders, in proportion (as
          nearly as practicable) to the amount of Registrable Stock requested to
          be included in such registration by each Holder at the time of filing
          the registration statement; PROVIDED, that in the event of such
          limitation of the number of shares of Registrable Stock to be
          underwritten, the Holders shall be entitled to an additional demand
          registration pursuant to this Section 2.  If any Holder of Registrable
          Stock disapproves of the terms of the underwriting, such Holder may
          elect to withdraw by written notice to the Company, the managing
          underwriter and the Requesting Holders.  The securities so withdrawn
          shall also be withdrawn from registration.

               (d)  Notwithstanding any provision of this Agreement to the
          contrary, the Company shall not be required to effect a registration
          pursuant to this Section 2 during the period starting with the
          fourteenth day immediately preceding the date of an anticipated filing
          by the Company of, and ending on a date ninety (90) days following the
          effective date of, a registration statement pertaining to a public
          offering of securities for the account of the Company; PROVIDED, that
          the Company shall actively employ in good faith all reasonable efforts
          to cause such registration statement to become effective; and PROVIDED
          FURTHER, that the Company's estimate of the date of filing such
          registration statement shall be made in good faith.

               (e)  The Company shall be obligated to effect and pay for a total
          of only four (4) registrations pursuant to this Section 2, unless
          increased pursuant to Section 2(c) hereof; PROVIDED, that a
          registration requested pursuant to this Section


                                       -4-
<PAGE>

          2 shall not be deemed to have been effected for purposes of this
          Section 2(e), unless (i) it has been declared effective by the
          Commission, (ii) if it is a shelf registration, it has remained
          effective for the period set forth in Section 4(b), (iii) the offering
          of Registrable Stock pursuant to such registration is not subject to
          any stop order, injunction or other order or requirement of the
          Commission (other than any such action prompted by any act or omission
          of the Holders), and (iv) no limitation of the number of shares of
          Registrable Stock to be underwritten has been required pursuant to
          Section 2(c) hereof.

          3.   INCIDENTAL REGISTRATION.  If at any time the Company determines
that it shall file a registration statement under the 1933 Act (other than a
registration statement on a Form S-4 or S-8 or filed in connection with an
exchange offer or an offering of securities solely to the Company's existing
stockholders) on any form that would also permit the registration of the
Registrable Stock and such filing is to be on its behalf and/or on behalf of
selling holders of its securities for the general registration of its common
stock to be sold for cash, at each such time the Company shall promptly give
each Holder written notice of such determination setting forth the date on which
the Company proposes to file such registration statement, which date shall be no
earlier than forty (40) days from the date of such notice, and advising each
Holder of its right to have Registrable Stock included in such registration.
Upon the written request of any Holder received by the Company no later than
twenty (20) days after the date of the Company's notice, the Company shall use
its best efforts to cause to be registered under the 1933 Act all of the
Registrable Stock that each such Holder has so requested to be registered.  If,
in the written opinion of the managing underwriter or underwriters (or, in the
case of a non-underwritten offering, in the written opinion of the placement
agent, or if there is none, the Company), the total amount of such securities to
be so registered, including such Registrable Stock, will exceed the maximum
amount of the Company's securities which can be marketed (i) at a price
reasonably related to the then current market value of such securities, or (ii)
without otherwise materially and adversely affecting the entire offering, then
the amount of Registrable Stock to be offered for the accounts of Holders shall
be reduced pro rata to the extent necessary to reduce the total amount of
securities to be included in such offering to the recommended amount; PROVIDED,
that if securities are being offered for the account of other Persons as well as
the Company, such reduction shall not represent a greater fraction of the number
of securities intended to be offered by Holders than the fraction of similar
reductions imposed on such other Persons other than the Company over the amount
of securities they intended to offer.

          4.   OBLIGATIONS OF THE COMPANY.  Whenever required under Section 2 to
use its best efforts to effect the registration of any Registrable Stock, the
Company shall, as expeditiously as possible:

               (a)  prepare and file with the Commission, not later than sixty
          (60) days after receipt of a request to file a registration statement
          with respect to such

          Registrable Stock, a registration statement on any form for which the
          Company then qualifies or which counsel for the Company shall deem
          appropriate and which form shall be available for the sale of such
          issue of Registrable Stock in accordance with the intended method of
          distribution thereof, and use its best efforts to cause such
          registration statement to become effective as promptly as practicable
          thereafter; PROVIDED that before filing a registration statement or
          prospectus or any amendments or supplements thereto, the Company will
          (i) furnish to one counsel selected by the Requesting Holders copies
          of all such documents proposed to be filed, and (ii) notify each such
          Holder of any stop order issued or threatened by the Commission and
          take all reasonable actions required to prevent the entry of such stop
          order or to remove it if entered;

               (b)  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 for a period of not less than one hundred twenty
          (120) days or such shorter period which will terminate when all
          Registrable Stock covered by such registration statement has been sold
          (but not before the expiration of the forty (40) or ninety (90) day
          period referred to in Section 4(3) of the 1933 Act and Rule 174
          thereunder, if applicable), and comply with the provisions of the 1933
          Act with respect to the disposition of all securities covered by such
          registration statement during such period in accordance with the
          intended methods of disposition by the sellers thereof set forth in
          such registration statement;

               (c)  furnish to each Holder and any underwriter of Registrable
          Stock to be included in a registration statement copies of such
          registration statement as filed and each amendment and supplement
          thereto (in each case including all exhibits thereto), the prospectus
          included in such registration statement (including each preliminary
          prospectus) and such other documents as such Holder may reasonably
          request in order to facilitate the disposition of the Registrable
          Stock owned by such Holder;

               (d)  use its best efforts to register or qualify such Registrable
          Stock under such other securities or blue sky laws of such
          jurisdictions as any selling Holder or any underwriter of Registrable
          Stock reasonably requests, and do any and all other acts which may be
          reasonably necessary or advisable to enable such Holder to consummate
          the disposition in such jurisdictions of the Registrable Stock owned
          by such Holder; PROVIDED that the Company will not be required to (i)
          qualify generally to do business in any jurisdiction where it would
          not otherwise be required to qualify but for this paragraph 4(d), (ii)
          subject itself to taxation in any


                                       -6-
<PAGE>

          such jurisdiction, or (iii) consent to general service of process in
          any such jurisdiction;

               (e)  use its best efforts to cause the Registrable Stock covered
          by such registration statement to be registered with or approved by
          such other governmental agencies or other authorities as may be
          necessary by virtue of the business and operations of the Company to
          enable the selling Holders thereof to consummate the disposition of
          such Registrable Stock;

               (f)  notify each selling Holder of such Registrable Stock and any
          underwriter thereof, at any time when a prospectus relating thereto is
          required to be delivered under the 1933 Act (even if such time is
          after the period referred to in Section 4(b)), of the happening of any
          event as a result of which the prospectus included in such
          registration statement contains an untrue statement of a material fact
          or omits to state any material fact required to be stated therein or
          necessary to make the statements therein in light of the circumstances
          being made not misleading, and prepare a supplement or amendment to
          such prospectus so that, as thereafter delivered to the purchasers of
          such Registrable Stock, such prospectus will not contain an untrue
          statement of a material fact or omit to state any material fact
          required to be stated therein or necessary to make the statements
          therein in light of the circumstances being made not misleading;

               (g)  make available for inspection by any selling Holder, any
          underwriter participating in any disposition pursuant to such
          registration statement, and any attorney, accountant or other agent
          retained by any such seller or underwriter (collectively, the
          "Inspectors"), all financial and other records, pertinent corporate
          documents and properties of the Company (collectively, the "Records"),
          and cause the Company's officers, directors and employees to supply
          all information reasonably requested by any such Inspector, as shall
          be reasonably necessary to enable them to exercise their due diligence
          responsibility, in connection with such registration statement.
          Records or other information which the Company determines, in good
          faith, to be confidential and which it notifies the Inspectors are
          confidential shall not be disclosed by the Inspectors unless (i) the
          disclosure of such Records or other information is necessary to avoid
          or correct a misstatement or omission in the registration statement,
          or (ii) the release of such Records or other information is ordered
          pursuant to a subpoena or other order from a court of competent
          jurisdiction.  Each selling Holder shall, upon learning that
          disclosure of such Records or other information is sought in a court
          of competent jurisdiction, give notice to the Company and allow the
          Company, at the Company's expense, to undertake appropriate action to
          prevent disclosure of the Records or other information deemed
          confidential;

               (h)  furnish, at the request of any Requesting Holder, on the
          date that such shares of Registrable Stock are delivered to the
          underwriters for sale pursuant to such registration or, if such
          Registrable Stock is not being sold through underwriters, on the date
          that the registration statement with respect to such shares of
          Registrable Stock becomes effective, (1) a signed opinion, dated such
          date, of the legal counsel representing the Company for the purposes
          of such registration, addressed to the underwriters, if any, and if
          such Registrable Stock is not being sold through underwriters, then to
          the Requesting Holders as to such matters as such underwriters or the
          Requesting Holders, as the case may be, may reasonably request and as
          would be customary in such a transaction; and (2) a letter dated such
          date, from the independent certified public accountants of the
          Company, addressed to the underwriters, if any, and if such
          Registrable Stock is not being sold through underwriters, then to the
          Requesting Holders and, if such accountants refuse to deliver such
          letter to such Holder, then to the Company (i) stating that they are
          independent certified public accountants within the meaning of the
          1933 Act and that, in the opinion of such accountants, the financial
          statements and other financial data of the Company included in the
          registration statement or the prospectus, or any amendment or
          supplement thereto, comply as to form in all material respects with
          the applicable accounting requirements of the 1933 Act, and (ii)
          covering such other financial matters (including information as to the
          period ending not more than five (5) business days prior to the date
          of such letter) with respect to the registration in respect of which
          such letter is being given as the Requesting Holders may reasonably
          request and as would be customary in such a transaction;

               (i)  enter into customary agreements (including if the method of
          distribution is by means of an underwriting, an underwriting agreement
          in customary form) and take such other actions as are reasonably
          required in order to expedite or facilitate the disposition of the
          Registrable Stock to be so included in the registration statement;

               (j)  otherwise use its best efforts to comply with all applicable
          rules and regulations of the Commission, and make available to its
          security holders, as soon as reasonably practicable, but not later
          than eighteen (18) months after the effective date of the registration
          statement, an earnings statement covering the period of at least
          twelve (12) months beginning with the first full month after the
          effective date of such registration statement, which earnings
          statements shall satisfy the provisions of Section 11(a) of the 1933
          Act; and


                                       -8-
<PAGE>

               (k)  use its best efforts to cause all such Registrable Stock to
          be listed on the New York Stock Exchange and/or any other securities
          exchange on which similar securities issued by the Company are then
          listed, or traded on the National Association of Securities Dealers
          Automated Quotations System, if such listing or trading is then
          permitted under the rules of such exchange or system, respectively.

          The Company may require each selling Holder of Registrable Stock as to
which any registration is being effected to furnish to the Company such
information regarding the distribution of such Registrable Stock as the Company
may from time to time reasonably request in writing.

          Each Holder agrees that, upon receipt of any notice from the Company
of the happening of any event of the kind described in Section 4(f) hereof, such
Holder will forthwith discontinue disposition of Registrable Stock pursuant to
the registration statement covering such Registrable Stock until such Holder's
receipt of the copies of the supplemented or amended prospectus contemplated by
Section 4(f) hereof, and, if so directed by the Company, such Holder will
deliver to the Company (at the Company's expense) all copies, other than
permanent file copies then in such Holder's possession, of the prospectus
covering such Registrable Stock current at the time of receipt of such notice.
In the event the Company shall give any such notice, the Company shall extend
the period during which such registration statement shall be maintained
effective pursuant to this Agreement (including the period referred to in
Section 4(b)) by the number of days during the period from and including the
date of the giving of such notice pursuant to Section 4(f) hereof to and
including the date when each selling Holder of Registrable Stock covered by such
registration statement shall have received the copies of the supplemented or
amended prospectus contemplated by Section 4(f) hereof.

          5.   HOLDBACK AGREEMENT.

               (a)  RESTRICTIONS ON PUBLIC SALE BY HOLDER.  To the extent not
          inconsistent with applicable law, each Holder whose Registrable Stock
          is included in a registration statement agrees not to effect any
          public sale or distribution of the issue being registered or a similar
          security of the Company, or any securities convertible into or
          exchangeable or exercisable for such securities, including a sale
          pursuant to Rule 144 under the 1933 Act, during the fourteen (14) days
          prior to, and during the ninety (90) day period beginning on, the
          effective date of such registration statement (except as part of the
          registration), if and to the extent requested by the Company in the
          case of a non-underwritten public offering or if and to the extent
          requested by the managing underwriter or underwriters in the case of
          an underwritten public offering.


                                       -9-
<PAGE>

               (b)  RESTRICTIONS ON PUBLIC SALE BY THE COMPANY AND OTHERS.  The
          Company agrees (i) not to effect any public sale or distribution of
          any securities similar to those being registered, or any securities
          convertible into or exchangeable or exercisable for such securities,
          during the fourteen (14) days prior to, and during the ninety (90) day
          period beginning on, the effective date of any registration statement
          in which Holders are participating (except as part of such
          registration), if and to the extent requested by the Holders in the
          case of a non-underwritten public offering or if and to the extent
          requested by the managing underwriter or underwriters in the case of
          an underwritten public offering; and (ii) that any agreement entered
          into after the date of this Agreement pursuant to which the Company
          issues or agrees to issue any securities convertible into or
          exchangeable or exercisable for such securities (other than pursuant
          to an effective registration statement) shall contain a provision
          under which holders of such securities agree not to effect any public
          sale or distribution of any such securities during the periods
          described in (i) above, in each case including a sale pursuant to Rule
          144 under the 1933 Act.

          6.   EXPENSES OF REGISTRATION.  All expenses incurred in connection
with each registration pursuant to Sections 2 and 3 of this Agreement, excluding
underwriters' discounts and commissions, but including, without limitation, all
registration, filing and qualification fees, word processing, duplicating,
printers' and accounting fees (including the expenses of any special audits or
"cold comfort" letters required by or incident to such performance and
compliance), exchange listing fees or National Association of Securities Dealers
fees, messenger and delivery expenses, all fees and expenses of complying with
securities or blue sky laws, fees and disbursements of counsel for the Company,
and the reasonable fees and disbursements of one (1) counsel for the selling
Holders shall be paid by the Company.  The selling Holders shall bear and pay
the underwriting commissions and discounts applicable to the Registrable Stock
offered for their account in connection with any registrations, filings and
qualifications made pursuant to this Agreement.

          7.   INDEMNIFICATION AND CONTRIBUTION.

               (a)  INDEMNIFICATION BY THE COMPANY.  The Company agrees to
          indemnify, to the full extent permitted by law, each Holder, its
          officers, directors and agents and each Person who controls such
          Holder (within the meaning of the 1933 Act) against all losses,
          claims, damages, liabilities and expenses caused by any untrue or
          alleged untrue statement of material fact contained in any
          registration statement, prospectus or preliminary prospectus or any
          omission or alleged omission to state therein a material fact required
          to be stated therein or necessary to make the statement therein (in
          case of a prospectus or preliminary prospectus, in the light of the
          circumstances under which they were made) not misleading, except
          insofar


                                      -10-
<PAGE>

          as the same are caused by or contained in any information with respect
          to such Holder furnished in writing to the Company by such Holder
          expressly for use therein or by such Holder's failure to deliver a
          copy of the registration statement or prospectus or any amendments or
          supplements thereto after the Company's compliance with Section 4(c)
          hereof.  The Company will also indemnify any underwriters of the
          Registrable Stock, their officers and directors and each Person who
          controls such underwriters (within the meaning of the 1933 Act) to the
          same extent as provided above with respect to the indemnification of
          the selling Holders.

               (b)  INDEMNIFICATION BY HOLDERS.  In connection with any
          registration statement in which a Holder is participating, each such
          Holder will furnish to the Company in writing such information with
          respect to such Holder as the Company reasonably requests for use in
          connection with any such registration statement or prospectus and
          agrees to indemnify, to the extent permitted by law, the Company, its
          directors and officers and each Person who controls the Company
          (within the meaning of the 1933 Act) against any losses, claims,
          damages, liabilities and expenses resulting from any untrue or alleged
          untrue statement of material fact  or any omission or alleged omission
          of a material fact required to be stated in the registration
          statement, prospectus or preliminary prospectus or any amendment
          thereof or supplement thereto or necessary to make the statements
          therein (in the case of a prospectus or preliminary prospectus, 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 contained in any information with respect to such Holder
          so furnished in writing by such Holder.  Notwithstanding the
          foregoing, the liability of each such Holder under this Section 7(b)
          shall be limited to an amount equal to the initial public offering
          price of the Registrable Stock sold by such Holder, unless such
          liability arises out of or is based on willful misconduct of such
          Holder.

               (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
          and, unless 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 claims 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).  Failure


                                      -11-
<PAGE>

          by such Person to provide said notice to the indemnifying party shall
          itself not create liability except to the extent of any injury caused
          thereby.  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 of more than one (1) counsel
          with respect to such claim, unless in the reasonable judgment of any
          indemnified party a conflict of interest may exist between such
          indemnified party and any other 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.

               (d)  CONTRIBUTION.  If for any reason the indemnity provided for
          in this Section 7 is unavailable to, or is insufficient to hold
          harmless, an indemnified party, then the indemnifying party shall
          contribute to the amount paid or payable by the indemnified party as a
          result of such losses, claims, damages, liabilities or expenses (i) in
          such proportion as is appropriate to reflect the relative benefits
          received by the indemnifying party on the one hand and the indemnified
          party on the other, or (ii) if the allocation provided by clause (i)
          above is not permitted by applicable law, or provides a lesser sum to
          the indemnified party than the amount hereinafter calculated, in such
          proportion as is appropriate to reflect not only the relative benefits
          received by the indemnifying party on the one hand and the indemnified
          party on the other but also the relative fault of the indemnifying
          party and the indemnified party as well as any other relevant
          equitable considerations.  The relative fault of such indemnifying
          party and indemnified parties shall be determined by reference to,
          among other things, whether any action in question, including any
          untrue or alleged untrue statement of a material fact or omission or
          alleged omission to state a material fact, has been made by, or
          relates to information supplied by, such indemnifying party or
          indemnified parties; and the parties' relative intent, knowledge,
          access to information and opportunity to correct or prevent such
          action.  The amount paid or payable by a party as a result of the
          losses, claims, damages, liabilities and expenses referred to above
          shall be deemed to include, subject to the limitations set forth in
          Section 7(c), any legal or other fees or expenses reasonably incurred
          by such party in connection with any investigation or proceeding.


                                      -12-
<PAGE>

               The parties hereto agree that it would not be just and equitable
          if contribution pursuant to this Section 7 (d) were determined by pro
          rata allocation or by any other method of allocation which does not
          take account of the equitable considerations referred to in the
          immediately preceding paragraph.  No Person guilty of fraudulent
          misrepresentation (within the meaning of Section 11(f) of the 1933
          Act) shall be entitled to contribution from any Person who was not
          guilty of such fraudulent misrepresentation.

               If indemnification is available under this Section 7, the
          indemnifying parties shall indemnify each indemnified party to the
          full extent provided in Sections 7(a) and (b) without regard to the
          relative fault of said indemnifying party or indemnified party or any
          other equitable consideration provided for in this Section 7.

           8.  PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.  No Holder may
participate in any underwritten registration hereunder unless such Holder (a)
agrees to sell such Holder's securities on the basis provided in any
underwriting arrangements approved by the Holders entitled hereunder to approve
such arrangements, and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

          9.   RULE 144.  The Company covenants that it will file the reports
required to be filed by it under the 1933 Act and the Securities Exchange Act of
1934, as amended, and the rules and regulations adopted by the Commission
thereunder; and it will take such further action as any Holder may reasonably
request, all to the extent required from time to time to enable such Holder to
sell Registrable Stock without registration under the 1933 Act within the
limitation of the exemptions provided by (a) Rule 144 under the 1933 Act, as
such Rule may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the Commission.  Upon the request of any Holder,
the Company will deliver to such Holder a written statement as to whether it has
complied with such requirements.

          10.  TRANSFER OF REGISTRATION RIGHTS.  The registration rights of any
Holder under this Agreement with respect to any Registerable stock may be
transferred to any transferee of such Registrable Stock; PROVIDED that such
transfer may otherwise be effected in accordance with applicable securities

          previously entered into any agreement with respect to any of its
          securities granting any registration rights to any Person, other than
          agreements which by reason of lapse of time do not require the Company
          as a practical matter to register any securities for any Person.

               (b)  REMEDIES.  Each Holder, in addition to being entitled to
          exercise all rights granted by law, including recovery of damages,
          will be entitled to specific performance of its rights under this
          Agreement.  The Company agrees that monetary damages would not be
          adequate compensation for any loss incurred by reason of a breach by
          it of the provisions of this Agreement and hereby agrees to waive (to
          the extent permitted by law) the defense in any action for specific
          performance that a remedy of law would be adequate.

               (c)  AMENDMENTS AND WAIVERS.  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 obtained the written consent of the Holders of at least a
          majority of the Registrable Stock then outstanding affected by such
          amendment, modification, supplement, waiver or departure.

               (d)  SUCCESSORS AND ASSIGNS.  Except as otherwise expressly
          provided herein, the terms and conditions of this Agreement shall
          inure to the benefit of and be binding upon the respective successors
          and assigns of the parties hereto.  Nothing in this Agreement,,
          express or implied, is intended to confer upon any Person other than
          the parties hereto or their respective successors and assigns any
          rights, remedies, obligations, or liabilities under or by reason of
          this Agreement, except as expressly provided in this Agreement.

               (e)  GOVERNING LAW.  This Agreement shall be governed by and
          construed in accordance with the internal laws of the State of New

          counterparts, each of which shall be deemed an original, but all of

     that the thirty (30) day cure period specified in Section 1.1(c)(iv) of the
     Underlying Agreement has expired without such default being cured, and
     (iii) the dollar amount of the default, the Escrow Agent shall promptly
     deliver to the PESA Escrow Account 2,083 Acquisition Shares (with their

               (c)  The Escrow Agent shall, at any time, deliver such part of
     the Escrowed Property as shall be set forth in an affidavit signed by the
     PESA Escrow Agent, the CCACB Representative and the WPG Representative.

               (d)  The Escrow Agent shall, at any time, deliver such part of
     the Escrowed Property as shall be set forth in any order, decree, or
     judgment of a court of competent jurisdiction which has been finally
     affirmed on appeal or which, by lapse of time or otherwise, is not subject
     to appeal.

     All distributions of the Escrowed Property shall be subject to the claims
of Escrow Agent and the Indemnified Parties (as defined below) pursuant to
Section 9 below.


          5. DELIVERY INTO COURT.  If, at any time, there shall exist any
dispute between PESA, the Purchasers, or the Representatives with respect to the
holding or disposition of any portion of the Escrowed Property or any other
obligations of Escrow Agent hereunder, or if at any time the Escrow Agent is
unable to determine, to Escrow Agent's sole satisfaction, the proper disposition
of any portion of the Escrowed Property or Escrow Agent's proper actions with
respect to its obligations hereunder, or if the Representatives have not, within
thirty (30) days of the furnishing by Escrow Agent of a notice of resignation
pursuant to Section 7 hereof, appointed a successor Escrow Agent to act
hereunder, then Escrow Agent may, in its sole discretion, take either or both or
the following actions:

               (a)  suspend the performance of any of its obligations under this
     Escrow Agreement until such dispute or uncertainty shall be resolved to the
     sole satisfaction of Escrow Agent or until a successor Escrow Agent shall
     have been appointed (as the case may be); provided, however, that Escrow
     Agent shall continue to hold the Escrowed Property safely until directed as
     to distribution by the court; and/or


                                       -4-
<PAGE>


               (b)  petition (by means of an interpleader action or any other
     appropriate method) any court of competent jurisdiction in New York, New
     York, for instructions with respect to such dispute or uncertainty, and
     disposition in accordance with the instructions of such court.

The Escrow Agent shall have no liability to PESA, the Purchasers, their
respective shareholders or any other person with respect to any such suspension
of performance or disbursement or distribution into court, specifically
including any liability or claimed liability that may arise, or be alleged to
have arisen, out of or as a result of any delay in the delivery of the Escrowed
Property or any delay in or with respect to any other action required or
requested of Escrow Agent.


          6. INTENTIONALLY DELETED.


          7. RESIGNATION AND REMOVAL OF ESCROW AGENT.  Escrow Agent may resign
from the performance of its duties hereunder at any time by giving ten (10) days
prior written notice to the Representatives or may be removed, with or without
cause, by the Representatives, acting jointly by furnishing a Joint Written
Direction to Escrow Agent, at any time by the giving of ten (10) days prior
written notice to Escrow Agent.  Such resignation or removal shall take effect
upon the appointment of a successor Escrow Agent as provided hereinbelow.  Upon
any such notice of resignation or removal, the Representatives jointly shall
appoint a successor Escrow Agent hereunder, which shall be a United States
commercial bank, trust company, or other financial institution with a combined
capital and surplus in excess of $10,000,000 and not affiliated with PESA or the
Purchasers.  Upon the acceptance in writing of any appointment as Escrow Agent
hereunder by a successor Escrow Agent, such successor Escrow Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Escrow Agent, and the retiring Escrow Agent shall be
discharged from its duties and obligations under this Escrow Agreement, but
shall not be discharged from any liability for actions taken as Escrow Agent
hereunder prior to such succession.  After any retiring Escrow Agent's
resignation or removal, the provisions of this Escrow Agreement shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Escrow Agent under this Escrow Agreement.


          8. LIABILITY OF ESCROW AGENT.  Escrow Agent shall have no liability or
obligation with respect to the Escrowed Property except for Escrow Agent's
willful misconduct or gross negligence.  Escrow Agent's sole responsibility
shall be for the safekeeping and distribution of the Escrowed Property in
accordance with the terms of this Escrow Agreement.  Escrow Agent shall have no
implied duties or obligations and shall not be charged with knowledge or notice


                                       -5-
<PAGE>

of any fact or circumstance not specifically set forth herein.  Escrow Agent may
rely upon any instrument, not only as to its due execution, validity and
effectiveness, but also as to the truth and accuracy of any information
contained therein, which Escrow Agent shall, in good faith, believe to be
genuine, to have been signed or presented by the person or parties purporting to
sign the same, and to conform to the provisions of this Escrow Agreement.  In no
event shall Escrow Agent be liable for incidental indirect, special,
consequential or punitive damages.  Escrow Agent shall not be obligated to take
any legal action or commence any proceeding in connection with the Escrowed
Property, this Escrow Agreement, or the Underlying Agreement, or to appear in,
prosecute or defend any such legal action or proceeding.  Escrow Agent may
consult legal counsel selected by it in the event of any dispute or question as
to the construction of any of the provisions hereof or of any other agreement or
of its duties hereunder, and shall incur no liability and shall be fully
protected from any liability whatsoever in acting in accordance with the opinion
or instruction of such counsel.  PESA, CCACB, and the WPG Group, jointly and
severally, shall promptly pay, upon demand, the reasonable fees and expenses of
any such counsel.  The parties agree that the payment by Pesa or CCACB, or the
WPG Group for the reasonable fees and expenses of the Escrow Agent's legal
counsel hereunder shall not impair, limit, modify, or affect, the respective
rights and obligations as between PESA, CCACB, the WPG Group and the other
Purchasers and the respective rights of each of PESA, CCACB, and the WPG Group
and the other Purchasers as against each other.


          9. INDEMNIFICATION OF ESCROW AGENT.  From and at all times after the
date of this Escrow Agreement, PESA, CCACB, and the WPG Group jointly and
severally, shall, to the fullest extent permitted by law and to the extent
provided herein, indemnify and hold harmless Escrow Agent and each director,
officer, employee, attorney, agent and affiliate of Escrow Agent (collectively,
the "Indemnified Parties") against any and all actions, (whether or not valid),
losses, damages, liabilities, costs and expenses of any kind or nature
whatsoever (including, without limitation, reasonable attorneys' fees, costs and
expenses) incurred by or asserted against any of the Indemnified Parties from
and after the date hereof, whether direct, indirect or consequential as a result
of or arising from or in any way relating to any claim, demand, suit, action or
proceeding (including any inquiry or investigation) by any person, whether
threatened or initiated, asserting a claim for any legal or equitable remedy
against any person under any statute or regulation, including, but not limited
to, any federal or state securities laws, or under any common law or equitable
cause or otherwise) arising from or in connection with the negotiation,
preparation, execution, performance or failure of performance of this Escrow
Agreement or any transactions contemplated herein, whether or not any such
Indemnified Party is a party to any such action, proceeding, suit or the target
of any such inquiry or investigation; provided, however, that no Indemnified
Party shall have the right to be indemnified hereunder for any liability finally
determined by a court of competent jurisdiction, subject to no further appeal,
to have resulted solely from the gross negligence or willful misconduct of such
Indemnified Party.  If any such action or claim shall be brought or


                                       -6-
<PAGE>

asserted against any Indemnified Party, such Indemnified Party shall promptly
notify PESA, CCACB, and the WPG Group in writing, and PESA, CCACB, and the WPG
Group shall assume the defense thereof, including the employment of counsel and
the payment of all expenses.  Such Indemnified Party shall, in its sole
discretion, have the right to employ separate counsel in any such action and to
participate in the defense thereof, and the fees and expenses of such counsel
shall be paid by such Indemnified Party unless (a) PESA and/or CCACB and/or the
WPG Group agree to pay such fees and expenses, or (b) PESA and/or CCACB and/or
the WPG Group shall fail to assume the defense of such action or proceeding or
shall fail, in the reasonable discretion of such Indemnified Party, to employ
counsel satisfactory to the Indemnified Party in any such action or proceeding,
or (c) the named parties to any such action or proceeding (including any
impleaded parties) include both Indemnified Party and PESA and/or CCACB and/or
the WPG Group, and Indemnified Party shall have been advised by counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to PESA or CCACB or the WPG Group.  All such
fees and expenses payable by PESA and/or CCACB and/or the WPG Group pursuant to
the foregoing sentence shall be paid from time to time as incurred, both in
advance of and after the final disposition of such action or claim.  All of the
foregoing losses, damages, costs and expenses of the Indemnified Parties shall
be payable by PESA and CCACB and the WPG Group, jointly and severally, upon
demand by such Indemnified Party.  The obligations of PESA and CCACB and the WPG
Group under this Section 9 shall survive any termination of this Escrow
Agreement and the resignation or removal of Escrow Agent.

     The parties agree that the payment by PESA or CCACB or the WPG Group of any
claim by Escrow Agent for indemnification hereunder in respect of a claim by
Escrow Agent for indemnification shall not impair, limit, modify, or affect, the
respective rights and obligations as between PESA, CCACB, the WPG Group, and the
other Purchasers and the respective rights of each of PESA, CCACB, the WPG Group
and the other Purchasers as against each other.


          10. FEES AND EXPENSES OF ESCROW AGENT.  PESA, CCACB and the WPG Group
shall compensate Escrow Agent for its services hereunder in accordance with
Schedule C attached hereto, except that the WPG Group shall not be responsible
for any payments due at Closing as defined in the Underlying Agreement.  PESA,
CCACB and the WPG Group shall reimburse Escrow Agent for all of its reasonable
out-of-pocket expenses, including attorneys' fees, travel expenses, telephone
and facsimile transmission costs, postage (including express mail and overnight
delivery charges), copying charges and the like.  All of the compensation and
reimbursement obligations set forth in this Section 10 shall be payable by PESA,
CCACB and the WPG Group, jointly and severally, upon demand by Escrow Agent.
The obligations of PESA, CCACB and the WPG Group under this Section 10 shall
survive any termination of this Escrow Agreement and the resignation or removal
of Escrow Agent.

          including, without limitation, the Underlying Agreement, to which PESA
