be removed (with or without cause) by written notice thereof to the other
Stockholders of the Company, then such director shall be removed, upon the
affirmative vote of holders of a majority of the outstanding shares of Common
Stock, and each Stockholder hereby agrees to vote all Shares owned or held of
record by such persons or entities to effect such removal upon such request.

         (d)  In the event a vacancy is created on the Board of Directors at
any time by the death, disability, retirement, resignation or removal of a
director or otherwise, the Stockholder who originally designated such director
shall nominate a replacement director, and each Stockholder agrees to cause the
director(s) designated by such Stockholder to vote for such nominated individual
to fill such vacancy.

         In addition, Stockholders may transfer Shares in connection with a

         (a)  If the Company elects to offer Common Stock pursuant to a
Qualified IPO

or is required to make a registration that would constitute a Qualified IPO, the
Board of Directors shall deliver a written notice to each of the Stockholders at
least 30 days prior to the filing of the initial registration statement in
connection with such Qualified IPO (the "IPO Notice").  Within 10 days of
receipt of such notice, the DLJ Investors may elect to participate in such
Qualified IPO as a selling Stockholder by delivering to the Company and each
other Stockholder, a notice stating (i) the DLJ Investors' bona fide intention
of participating in such Qualified IPO and (ii) and the number of Shares the DLJ
Investors wish to sell in such Qualified IPO.  The number of Shares that the DLJ
Investors may include in the Qualified IPO will be determined in accordance with

                       RIGHT OF FIRST OFFER; TAG-ALONG RIGHTS;
              CERTAIN PURCHASE RIGHTS; SHARES SUBJECT TO THIS AGREEMENT

    4.1. RIGHT OF FIRST OFFER.

         (a)  GENERAL.  If, prior to the consummation of a Qualified IPO, a
Stockholder ("Selling Stockholder") proposes to sell Shares to a third party
other than pursuant to an Exempt Transfer (a "PROPOSED SALE"), the Selling
Stockholder must first comply with the procedures set forth in this Section 4.1
and in Section 4.2.

              (i)   The consideration for the Proposed Sale shall consist
         solely of cash.

              (ii)  The Selling Stockholder shall deliver a notice (the
         "OFFERING NOTICE") to the Company and to each of the Stockholders
         stating (1) the Selling Stockholder's bona fide intention to sell
         Shares in the Proposed Sale; (2) the number of Shares it proposes to
         sell; and (3) the price and terms of the Proposed Sale.

              (iii) Within 20 days after the Offering Notice is given, the
         Company may elect by written notice to the Selling Stockholder to
         purchase from the Selling Stockholder, at the price and on the terms
         specified in the Offering Notice, any or all of the Shares proposed to
         be sold in the Proposed Sale; PROVIDED, HOWEVER, that in the event the
         Company elects to purchase some but not all of the Shares proposed to
         be sold in the Proposed Sale, the Company's right to purchase such
         Shares will be conditioned upon the purchase of the remainder of such
         Shares by the Stockholders pursuant to Section 4.1(a)(v) and (vi).

              (iv)  Subject to Subsection 4.1(a)(vi), the purchase of such
         Shares by the Company shall take place within 20 days after the date
         of the Company's notice.

              (v)   In the event the Company does not elect to purchase all of
         the Shares offered in the Offering Notice, the Company shall give
         written notice to each of the Stockholders (the "REOFFER NOTICE"), of
         the number of Shares available for purchase (the "REOFFERED SHARES")
         on or before the final day of such 20-day period and the right to
         purchase such Reoffered Shares shall pass automatically to each of
         such Stockholders.  Each such Stockholder shall initially


                                          8

<PAGE>

         be entitled to purchase such Stockholder's Percentage Share of the
         Reoffered Shares.  In the event that any Shares remain after such
         allocation and Stockholders remain who desire to purchase additional
         Shares in excess of their Stockholder's Percentage Share, all of the
         remaining Shares which such Stockholders have elected to purchase shall
         be allocated to them PRO RATA based on the number of Shares held by
         them, or otherwise as agreed to among such remaining Stockholders.
         Each Stockholder will have 20 days from receipt of the Reoffer Notice
         to exercise its purchase rights under this Section 4.1 by written
         notice to the Selling Stockholder and to the Company.  The closing of
         any purchase and sale under this subsection shall be held within 20
         days following the exercise by such Stockholder of the purchase
         rights hereunder.

              (vi)  Such purchase rights shall only apply if the Company and
          the Stockholders, collectively, acquire all, but not less than all,
          of the Shares proposed to be sold in the Offering Notice.  In the
          event the Company elects to acquire some but not all of the Shares
          proposed to be sold in the Offer Notice, the Company's purchase of
          Shares shall occur simultaneously with the purchase of Shares by the
          Stockholders.

              (vii) In the event that the rights of first offer set forth in
          Section 4.1 are not exercised, and the Selling Stockholder, to the
          extent applicable, has complied with Section 4.2 below, the Selling
          Stockholder may sell, at any time within 120 days from the date of
          the Reoffer Notice, the number of Shares it proposed to sell in the
          Proposed Sale on price and terms no less favorable to the purchaser
          than those of the Proposed Sale, provided that the Selling
          Stockholder may not sell such Shares to a Person if the Board of
          Directors has determined that such Person is reasonably likely to be
          a competitor of the Company or a person whose interests would be
          adverse to the Company.

    4.2.  TAG-ALONG RIGHT.  In the event that the rights of first offer set
forth in Section 4.1 are not exercised, each of the other Stockholders (the
"TAG-ALONG STOCKHOLDERS") shall have the right (the "TAG-ALONG RIGHT") to
include up to the following number of its Shares in the Proposed Sale:  the
total number of Shares proposed to be sold by the Selling Stockholder in the
Proposed Sale MULTIPLIED BY a fraction the numerator of which is the number of
Shares owned by such Tag-Along Stockholder and the denominator of which is the
aggregate number of Shares owned by such Selling Stockholder and by all
Tag-Along Stockholders exercising their Tag-Along Rights hereunder.  Any Shares
purchased from such Stockholders pursuant to this Section 4.2 shall be at the
same price per Share and upon the same terms and conditions as such Proposed
Sale.  The Selling Stockholder shall, not less than 30 days prior to each
Proposed Sale, notify, or cause to be notified, each Stockholder in writing of
each such Proposed Sale.  Such notice shall set forth:  (A) the name of the
Selling Stockholder and the number of Shares proposed to be sold, (B) the name
and address of the proposed purchaser, (C) the proposed per share purchase price
(which must be payable in cash) and the terms and conditions of payment offered
by such proposed purchaser, and (D) that the proposed purchaser has been
informed of the Tag-Along Right provided for in this Section 4.2 and has agreed
to purchase Shares in accordance with the terms hereof.


                                          9
<PAGE>

          The Tag-Along Right may be exercised by any Stockholder by delivery
of a written notice to the Selling Stockholder (the "TAG-ALONG NOTICE") within
15 business days following its receipt of the notice specified in the last
sentence of the preceding paragraph.  The Tag-Along Notice shall state the
number of Shares that such Stockholder proposes to include in such transfer to
the proposed purchaser determined as aforesaid.

          The Company agrees not to effect any transfer of Shares by any
Stockholder until it has received evidence reasonably satisfactory to it that
the Tag-Along Right, if applicable to such transfer, has been complied with.

          Notwithstanding the foregoing, (i) only GEI is entitled to exercise
Tag-Along Rights with respect to the first 335,000 Shares transferred by the DLJ
Investors and (ii) only the DLJ Investors are entitled to exercise Tag-Along
Rights with respect to the first 150,000 Shares transferred by GEI.

    4.3.  CERTAIN PREEMPTIVE RIGHTS.  If prior to a Qualified IPO the Company
proposes to issue, sell, or grant securities convertible into shares of Common
Stock (collectively, the "Securities"), then the Company shall, no later than
30 days prior to the consummation of such issuance, give written notice to all
Stockholders of such proposed issuance.  Such notice shall describe the proposed
issuance, and contain an offer to each of the Stockholders to sell to such
Stockholder, at the same price and for the same consideration to be paid by the
proposed purchasers, such Stockholder's pro rata portion (which shall be a
percentage equal to the percentage of the outstanding Common Stock held by such
Stockholder before such proposed issuance; PROVIDED, HOWEVER, that if the use of
proceeds of such Securities issuance shall include the repurchase of Common
Stock, then such percentage shall be calculated assuming the consummation of
such repurchase) of the Securities to be sold.  If any such Stockholder fails to
accept such offer by written notice within 25 days after its receipt of the
Company's notice, the Company may proceed with such proposed issuance, free of
any right on the part of such Stockholder under this Section 4.3 in respect
thereof.  This Section 4.3 shall not apply to:  (i) issuances to employees or
pursuant to employee benefit or stock option plans which shall not exceed 10% in
the aggregate of the shares of capital stock of the Company, on a fully diluted
basis; (ii) Securities distributed or set aside to all holders of Common Stock
on a per share equivalent basis; (iii) any other issuance of Securities pursuant
to or as a result of the transactions contemplated by the Recapitalization
Agreement or issuance of Securities upon the conversion, exercise or exchange of
such Securities or (iv) Securities issued in a business combination or
acquisition approved pursuant to Section 2.2.

    4.4   SHARES SUBJECT TO THIS AGREEMENT.  If, prior to a Qualified IPO, the
Company shall issue any Securities in a transaction as to which the rights under
Section 4.3 apply, or any Stockholder shall transfer Shares in a transaction
subject to Sections 4.1 and 4.2, the purchaser of such Securities shall execute
a copy of this Agreement and such purchaser shall be subject to this Agreement.

                                    MISCELLANEOUS

    5.1   LEGEND.  The certificates representing the Common Stock to be
purchased by each of the Stockholders shall bear the following legend:

              "THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
    TRANSFERRED, SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF
    (A "TRANSFER") EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF A STOCKHOLDERS
    AGREEMENT DATED AS OF JUNE 11, 1997.  SUCH SECURITIES ARE ALSO SUBJECT TO
    A REGISTRATION RIGHTS AGREEMENT DATED JUNE 11, 1997.  ANY TRANSFEREE OF
    THESE SECURITIES TAKES SUBJECT TO THE TERMS OF SUCH AGREEMENTS, COPIES OF
    WHICH ARE ON FILE WITH THE COMPANY.

              "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
    REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") OR UNDER ANY STATE
    SECURITIES LAWS.  THE SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE
    ABSENCE OF AN EXEMPTION THEREFROM UNDER THE ACT OR LAW OR THE RULES AND
    REGULATIONS PROMULGATED THEREUNDER."

    Each of the parties hereto agrees that it will not transfer any Shares
without complying with each of the restrictions set forth herein and agrees that
in connection with any such transfer it will, if requested by the Company,
deliver at its expense to the Company an opinion of counsel (including in-house
or special counsel), in form and substance reasonably satisfactory to the
Company and counsel for the Company, that such transfer is not in violation of
the securities laws of the United States of America or any state thereof;
PROVIDED, HOWEVER, that in case of any sale or other transfer of Shares to any
person or entity who is an "accredited investor" (as such term is defined and
used in Rule 501 of Regulation D under the Act), no opinion of counsel shall be
required if the transferor obtains a representation from such person or entity
that it is an accredited investor and is acquiring such Shares for its own
account and with no intention of distributing or reselling said Shares or any
part thereof, or interest therein, in any transaction that would violate the
securities laws of the United States of America or any state thereof, without
prejudice, however, to such person's or entity's right at all times to sell or
otherwise dispose of all or any part of said Shares pursuant to an effective
registration statement under the Act or any exemption from such registration
available under the Act, and subject, nevertheless, to such person's or entity's
disposition of its property being at all times within its control.

    5.2   TERMINATION OF SUCCESSION PLAN.  Upon the effective date of this
Agreement, the succession plan in the event of Gooding's death adopted by the
Company pursuant to a Board resolution dated as of June 27, 1994 shall terminate
and be of no further effect.

upon and inure to the benefit of the parties hereto and their respective legal
representatives, heirs, legatees, successors and assigns including any party to
which any Stockholder has transferred or sold his or its Shares.  Except as
provided herein, each transferee of Shares from a party hereto or a Permitted
Transferee thereof shall take such Shares subject to the same restrictions as
existed in the hands of the transferor; PROVIDED that if Gooding or an
Institutional Investor transfers Shares, the transferee shall only have rights
as a Stockholder hereunder and not the rights of Gooding or such Institutional
Investor.

    5.5   RECAPITALIZATIONS, ETC.  The provisions of this Agreement shall
apply, to the full extent set forth herein with respect to the Shares, to any
and all shares of capital stock of the Company or any capital stock, partnership
units or any other security evidencing ownership interests in any successor or
assign of the Company (whether by merger, consolidation, sale of assets or
otherwise) that may be issued in respect of, in exchange for, or in substitution
of the Common Stock by reason of any stock dividend, split, reverse split,
combination, recapitalization, liquidation, reclassification, merger,
consolidation or otherwise.

    5.6   LEAD UNDERWRITER.  As long as the DLJ Investors own 5% or more of the
outstanding Shares, DLJSC shall have the right but not the obligation to act as
the lead underwriter in a Qualified IPO.  If requested, the Stockholders agree
to vote in favor of such engagement.

    5.7   INSPECTION AND COMPLIANCE WITH LAW.  Copies of this Agreement will be
available for inspection or copying by any Stockholder at the offices of the
Company through the Secretary of the Company.
