matter to the [*] of [*] for resolution. If the chief executive officers so
agree the proposed Significant Board Transaction will be resubmitted for a vote
of the Company Board within ten days (or such shorter or longer period as they
may agree) after referral to the chief executive officers. Unless and until the
proposed Significant Board Transaction is so resubmitted, the initial vote of
the Company Board will continue to govern with respect to such matter.

     SECTION 6.07.  Budget Process.
                    -------------- 

          (a) The CEO shall submit annually to the Company Board at least ninety
(90) days prior to the start of each fiscal year of the Company after the fiscal

projected for the business of the Company for the forthcoming fiscal year and
the amount of any corresponding cash surplus or deficiency and any contemplated
borrowings of the Company.  If such Proposed Budget is approved by the Company
Board by Supermajority Board Vote, then such Proposed Budget shall be considered
approved and shall constitute the "Budget" for all purposes of this Agreement
and shall supersede any previously approved Budget.  If a Proposed Budget is not
approved by the requisite vote of the Company Board, then the directors of the
Company shall (and the Consenting Stockholders shall cause their designees on
the Company Board to) cooperate in good faith and confer with the CEO and other
senior officers of the Company for the purpose of attempting to arrive at a
Proposed Budget that can secure the approval of the Company Board.

          (b) If, notwithstanding the foregoing procedures, on January 1 of any
fiscal year of the Company no Proposed Budget has been approved by the Company
Board for such fiscal year, then the Budget for the prior fiscal year, adjusted
(without duplication) to reflect increases or decreases resulting from the
following events, shall govern until such time as the Company Board approves a
new Proposed Budget:

                    (i) the operation of escalation or de-escalation provisions
          in contracts in effect at the time of approval of the prior fiscal
          year's Budget solely as a result of the passage of time or the
          occurrence of events beyond the control of the Company to the extent
          such contracts are still in effect;

                    (ii) elections made in any prior fiscal year under contracts
          contemplated by the Budget for the prior fiscal year regardless of
          which party to such contracts made such elections;

                    (iii) increases or decreases in expenses attributable to
          the annualized effect of employee additions or reductions during the
          prior fiscal year contemplated by the Budget for the prior fiscal
          year;

                    (iv) changes in interest expense attributable to any loans
          made to or retired by the Company;

                    (v) increases in overhead expenses in an amount equal to the
          total of overhead expenses reflected in the Budget for the prior
          fiscal year multiplied by the increase in the Consumer Price Index for
          the prior year, but in no event more than five percent (5%);

                    (vi) the anticipated incurrence of costs during such fiscal
          year for any legal, accounting and other professional fees or
          disbursements in connection with events or changes not contemplated at
          the time the Budget for the fiscal year was adopted;

                    (vii) the continuation of the effects of a decision made by
          the Company Board or the Consenting Stockholders in the prior fiscal
          year with respect to any Significant Board Transaction or Significant
          Stockholder Transaction that are not reflected in the Budget; and

                    (viii) decreases in expense attributable to non-recurring
          items reflected in the prior fiscal year's Budget.

     Any budget established pursuant to this Section 6.07(b) is herein referred
to as a "Default Budget."  If on January 1 of any fiscal year the Company no
Proposed Budget has been approved by the Company Board for such fiscal year and
a Default Budget was in effect for the prior fiscal year, then such Default
Budget, adjusted (without duplication) to reflect increases or decreases
resulting from the events listed above (as if the references in the first
sentence of this Section 6.07(b) to "Budget" referred to such "Default Budget")
shall govern until the Company Board approves a new Proposed Budget.

     SECTION 7.01.  Restrictions on Transfers and Conversion.
                    ----------------------------------------

          (a) Prior to consummation of the Company's initial Public Offering, a
Consenting Stockholder shall not Dispose of any of its shares of Company Common
Stock, or convert any of its shares of Series B Stock into Series A Stock,
except for (i) a Transfer of all and not less than all of its shares of Company
Common Stock (x) to any of such Consenting Stockholder's Controlled Affiliates,
provided that the transferee assumes the obligations of the transferor under
this Agreement with respect to such shares and agrees to become a party to this
Agreement, (y) in compliance with Section 7.02, or (z) to another Consenting
Stockholder or its designee pursuant to Section 7.08 or 7.09; or (ii) a Transfer
of a portion of its shares of Company Common Stock to the extent required by
Section 7.10.

          (b) After consummation of the Company's initial Public Offering, a
Consenting Stockholder shall not Dispose of any of its shares of Series B Stock,
including by conversion into Series A Stock, except (i) for a Transfer of shares
of Series B Stock to any of such Consenting Stockholder's Controlled Affiliates,
provided that, in each case, the transferee assumes, jointly and severally with
the transferor if less than all of such shares of the transferor are
transferred, the obligations of the transferor under this Agreement with respect
to such shares and agrees to become a party to this Agreement; or (ii) in
compliance with Section 7.03 or 7.04.

          (c) Any attempt to Dispose of any shares of the Company Common Stock
or convert any shares of Series B Stock into Series A Stock, in a manner that
does not comply with this Agreement shall be ineffective.

          (d) Except as expressly permitted by this Agreement, each Consenting
Stockholder shall, from and after the Closing Date, (i) be the record and
beneficial owner of such shares of the Company Common Stock and other securities
of the Company indicated in the Company's records as being owned by such

Permitted Lien) of any kind, and (ii) have sole voting power with respect to
such Consenting Stockholder's shares of the Company Common Stock and will not
grant any proxy with respect to such shares, enter into any voting trust or
other voting agreement or arrangement with respect to such shares or grant any
other rights to vote such shares; provided, however, that the foregoing shall

not be construed to limit the ability of a Consenting Stockholder to enter into
agreements with respect to the voting of its shares of the Company Common Stock

agreements not inconsistent with this Agreement that restrict such Consenting
Stockholder's ability to transfer shares of the Company Common Stock.

     SECTION 7.02.  Pre-IPO Rights of First Refusal.
                    -------------------------------

          (a) After the third anniversary of the date of this Agreement and
prior to the consummation of the Company's initial Public Offering, if a
Consenting Stockholder ("Selling Stockholder") or its Parent shall receive at
any time a bona fide offer in writing, which the Selling Stockholder or its
Parent proposes to accept (a "Third Party Offer"), from a third party (the
"Third Party Offeror") to acquire all and not less than all of its shares of the
Company Common Stock (the "First Refusal Shares") or to effect an Indirect
Transfer (in which case the "First Refusal Shares" shall be all the shares of
the Company Common Stock owned by the Selling Stockholder), the Selling
Stockholder shall deliver to each other Consenting Stockholder (the "First
Refusal Stockholders") a notice (a "First Refusal Notice of Sale") containing a
copy of the Third Party Offer and setting forth the identity of the Third Party
Offeror and its Parent and an offer to sell the First Refusal Shares to the
First Refusal Stockholders on the following terms:  (i) if the Third Party Offer
contemplates a purchase of the First Refusal Shares by the Third Party Offeror
for consideration consisting solely of cash, then the Selling Stockholder's
offer shall be to sell the First Refusal Shares for cash in an amount equal to
the purchase price specified in, and otherwise on the terms and conditions
contained in, the Third Party Offer, and (ii) if the Third Party Offer
contemplates an acquisition of the First Refusal Shares by the Third Party
Offeror for consideration any portion of which is not cash or if the Third Party
Offer contemplates an Indirect Transfer, then the Selling Stockholder's offer
shall be to sell the First Refusal Shares for cash in an amount equal to the
fair market value of the noncash consideration or of the First Refusal Shares,
as applicable (as determined pursuant to Section 7.02(c), and otherwise on the
terms and conditions contained in the Third Party Offer.  The First Refusal
Notice of Sale shall specify the price at which the First Refusal Shares are
offered, as provided in the preceding sentence.  The First Refusal Stockholders
shall enter into an appropriate confidentiality agreement reasonably requested
by the Selling Stockholder with respect to the Third Party Offer.

               (i) If a First Refusal Stockholder desires to accept all or any
          portion of the offer set forth in a First Refusal Notice of Sale as to
          any part of the First Refusal Shares, such First Refusal Stockholder
          (a "First Refusal Electing Stockholder") shall, within ten Business
          Days of receipt of such First Refusal Notice of Sale, notify the
          Selling Stockholder of its intention to acquire First Refusal Shares
          and the number of such shares it desires to acquire, and deliver a
          copy of such notice to each other First Refusal Stockholder.

               (ii) If the First Refusal Electing Stockholders desire to
          acquire, in the aggregate, all of the First Refusal Shares, then the
          First Refusal Electing Stockholders shall have the right to acquire
          all the First Refusal Shares, allocated

          among them as follows (or in such other manner as the First Refusal
          Electing Stockholders may agree):

                    (A) the First Refusal Shares shall be allocated among the
               First Refusal Electing Stockholders pro rata (based on the number
               of shares of Series B Stock owned by each of them) until all of
               the First Refusal Shares have been allocated or any First Refusal
               Electing Stockholder has been allocated the number of First
               Refusal Shares that it desires to acquire, as specified in its
               notice to the Selling Stockholder, as it may have been amended
               pursuant to clause (iii);

                    (B) if all First Refusal Shares are not allocated pursuant
               to paragraph (A) or any prior application of this paragraph (B),
               any First Refusal Shares that were not allocated pursuant to
               paragraph (A) or any prior application of this paragraph (B)
               shall be allocated among the First Refusal Electing Stockholders
               (other than any First Refusal Electing Stockholder that has been
               allocated the number of First Refusal Shares that it desires to
               acquire, as specified in its notice to the Selling Stockholder,
               as it may have been amended pursuant to clause (iii)) pro rata
               (based on the number of shares of Series B Stock owned by each of
               them); and

                    (C) if all First Refusal Shares are not allocated pursuant
               to paragraph (A) and any prior application of paragraph (B), any
               First Refusal Shares that were not allocated pursuant to
               paragraph (A) and any prior application of paragraph (B) shall be
               allocated by continuing to apply paragraph (B) as required.

               (iii)  If the First Refusal Electing Stockholders desire to
          acquire, in the aggregate, less than all of the First Refusal Shares,
          then the Selling Stockholder shall so notify the First Refusal
          Electing Stockholders and:

                    (A) each First Refusal Electing Stockholder shall have the
               right, by written notice sent to the Selling Stockholder (with a
               copy of such notice to each other Consenting Stockholder) within
               five Business Days after its receipt of the notice from the
               Selling Stockholder pursuant to this clause (iii) to amend its
               notice to increase the number of First Refusal Shares that it
               desires to purchase;

                    (B) if, after giving effect to any amendment to any First
               Refusal Electing Stockholder's notice pursuant to this clause
               (iii), the First Refusal Electing Stockholders desire to acquire,
               in the aggregate, all of the First Refusal Shares, then the First
               Refusal Electing Stockholders shall have the

<PAGE>
 
               right to acquire all the First Refusal Shares, allocated among
               them in accordance with clause (ii); and

                    (C) if, after giving effect to any amendment to any First
               Refusal Electing Stockholder's notice pursuant to this clause
               (iii), the First Refusal Electing Stockholders desire to acquire,
               in the aggregate, less than all of the First Refusal Shares, then
               the Selling Stockholder's offer of the First Refusal Shares shall
               be deemed rejected as of the last day for a First Refusal
               Electing Stockholder to amend its notice pursuant to this clause
               (iii).

          (b) If (i) the Selling Stockholder's offer of the First Refusal Shares
is rejected as provided in Section 7.02(a), or (ii) the purchase of the First
Refusal Shares is not consummated within the period set forth in Section
7.05(a)(iii) for any reason other than a breach by the Selling Stockholder of
any of its covenants, representations or warranties that are a condition to
consummation of such purchase, then the Selling Stockholder shall have the
right, at any time during the sixty-day period beginning on the date that the
Seller Stockholder's offer of the First Refusal Shares is deemed rejected or the
day following the last day of the period set forth in Section 7.05(a)(iii), as
applicable, to enter into a binding agreement to sell all of the First Refusal
Shares to the Third Party Offeror, or to effect the Indirect Transfer
contemplated by the Third Party Offer, as applicable, in either case on terms
and conditions no less favorable in the aggregate to the Selling Stockholder
(and, in the case of an Indirect Transfer, its Parent) than those set forth in
the Third Party Offer, and thereafter (within the period specified below in this
Section 7.02(b)) to sell all of the First Refusal Shares to the Third Party
Offeror or effect the Indirect Transfer, as applicable, pursuant to such
agreement; provided that (i) in the case of a sale of First Refusal Shares, the
Third Party Offeror assumes the obligations of the Selling Stockholder under
this Agreement with respect to such shares and becomes a party to this
Agreement, and (ii) in the case of an Indirect Transfer, the Third Party
Offeror, upon taking control of the Selling Stockholder causes the Selling
Stockholder to confirm in writing the continuing validity and effectiveness of
its obligations under this Agreement, and in such case, its [*] to the [*] to
its [*] [*] equivalent to the [*] pursuant to the [*] Agreement if the [*] set
forth in Section [*] hereof has been [*]. The Selling Stockholder shall, as
promptly as practicable and prior to the closing of such sale or Indirect
Transfer, provide to the First Refusal Stockholders a copy of the agreement for
the sale of the First Refusal Shares so as to permit the First Refusal
Stockholders to confirm for themselves that the terms and conditions of such
sale are not less favorable in the aggregate to the Selling Stockholder (and, in
the case of an Indirect Transfer, its [*]) than those set forth in the Third
Party Offer. If the Selling Stockholder does not enter into such an agreement
during such sixty-day period, or does not close the sale thereunder within sixty
days after the execution of such an agreement (subject to extension for a
maximum of one hundred eighty additional days to the extent required to obtain
all required Governmental and Private Approvals), the procedure set forth above
with respect to the First Refusal Notice of Sale shall be repeated with respect
to

any subsequent proposed sale, assignment or other disposition of shares of the
Company Common Stock by the Selling Stockholder.

          (c) Before submitting a First Refusal Notice of Sale pursuant to
Section 7.02(a) in response to a Third Party Offer that contemplates (i) a sale
of the First Refusal Shares in conjunction with other assets, (ii) an
acquisition of the First Refusal Shares by the Third Party Offeror for
consideration any portion of which is not cash or (iii) an Indirect Transfer,
the Selling Stockholder and the other Consenting Stockholders shall cause (A) if
the Third Party Offer contemplates a sale of the First Refusal Shares in
conjunction with other assets, the total consideration specified in the Third
Party Offer to be allocated between the First Refusal Shares and such other
assets, (B) if the Third Party Offer contemplates an acquisition of the First
Refusal Shares by the Third Party Offeror for consideration any portion of which
is not cash or if the Third Party Offer contemplates an Indirect Transfer, the
fair market value of the noncash consideration or of the First Refusal Shares,
as applicable, to be determined, in each case pursuant to this Section 7.02(c):

               (i)    The Selling Stockholder shall deliver to each other
          Consenting Stockholder a notice stating that the Selling Stockholder
          intends to deliver a First Refusal Notice of Sale to which this
          Section 7.02(c) applies and identifying an appraiser (the "First
          Appraiser") who has been retained by the Selling Stockholder to
          allocate the total consideration specified in the Third Party Offer or
          to conduct an appraisal of the noncash consideration or of the First
          Refusal Shares, as applicable, pursuant to this Section 7.02(c).
          Within ten Business Days after its receipt of the Selling
          Stockholder's notice pursuant to the preceding sentence, the
          Consenting Stockholder (other than the Selling Stockholder) that,
          together with its Controlled Affiliates, owns the greatest number of
          shares of Series B Stock, shall send a notice to the Selling
          Stockholder and the other Consenting Stockholders identifying a second
          appraiser (the "Second Appraiser") who shall be retained by the
          Selling Stockholder to make such allocation or conduct such appraisal,
          as applicable, pursuant to this Section 7.02(c).

               (ii)   The First Appraiser and the Second Appraiser shall submit
          their independent determinations of the amount of consideration
          allocable to the First Refusal Shares or the fair market value of the
          noncash consideration or of the First Refusal Shares, as applicable,
          within thirty days after the date on which the Second Appraiser is
          retained.  If the respective determinations of the First Appraiser and
          the Second Appraiser vary by less than ten percent of the higher
          determination, the amount of consideration allocable to the First
          Refusal Shares or the fair market value of the noncash consideration
          or of the First Refusal Shares, as applicable, for purposes of Section
          7.02(a), shall be the average of the two determinations.

               (iii)  If the respective determinations of the First Appraiser
          and the Second Appraiser vary by ten percent or more of the higher
          determination, the 

                                       35
<PAGE>
 
          two Appraisers shall promptly designate a third appraiser (the "Third
          Appraiser"), who shall be retained by the Selling Stockholder to make
          an allocation or conduct an appraisal pursuant to this Section
          7.02(c). The First Appraiser and the Second Appraiser shall be
          instructed not to, and no party to this Agreement or any Controlled
          Affiliate of any party to this Agreement shall, provide any
          information to the Third Appraiser as to the determinations of the
          First Appraiser and the Second Appraiser or otherwise influence the
          Third Appraiser's determination in any way. The Third Appraiser shall
          submit its determination of the amount of consideration allocable to
          the First Refusal Shares or the fair market value of the noncash
          consideration or of the First Refusal Shares, as applicable, within
          thirty days after the date on which the Third Appraiser is retained.
          If a Third Appraiser is retained, the amount of consideration
          allocable to the First Refusal Shares or the fair market value of the
          noncash consideration or of the First Refusal Shares, as applicable,
          for purposes of Section 7.02(a), shall equal the average of the two
          closest of the three determinations, except that, if the difference
          between the highest and middle determinations is no more than [*] and
          no less than [*] of the difference between the middle and lowest
          determinations, then the amount of consideration allocable to the
          First Refusal Shares or the fair market value of the noncash
          consideration or of the First Refusal Shares, as applicable, for
          purposes of Section 7.02(a), shall equal the middle determination.

               (iv) Any appraiser retained pursuant to this Section 7.02(c)
          shall be nationally recognized as being qualified and experienced in
          the appraisal of assets comparable to the First Refusal Shares and, if
          applicable, any other assets proposed to be sold pursuant to the Third
          Party Offer and shall not be an Affiliate of any party to this
          Agreement.  All fees and expenses of any appraiser retained pursuant
          to this Section 7.02(c) shall be paid by the Selling Stockholder.

               (v) In determining the fair market value of the noncash
          consideration or of the First Refusal Shares, if applicable, each
          appraiser retained pursuant to this Section 7.02(c) shall: (A) assume
          that the fair market value of the applicable asset is the price at
          which the asset would change hands between a willing buyer and a
          willing seller, neither being under any compulsion to buy or sell and
          each having reasonable knowledge of all relevant facts; (B) assume
          that the applicable asset would be sold for cash; and (C) use
          valuation techniques then prevailing in the relevant industry.

                    --------------------------------------------------------
First Offer.
- -----------
             
          (a) No Consenting Stockholder shall convert any shares of Series B
Stock to Series A Stock prior to the consummation of the Company's initial
Public Offering.  After the consummation of the Company's initial Public
Offering, if a Consenting Stockholder (a "Converting Stockholder") desires to
convert all or any portion of its shares of Series B Stock to 

__________
[*] Confidential Treatment Requested.

                                       36

Series A Stock, it shall first deliver to each other Consenting Stockholder a
written notice (a "First Offer Notice of Sale") of its intention to so convert
such shares of Series B Stock (the "First Offer Shares"). The First Offer Notice
of Sale shall contain the Converting Stockholder's offer to sell the First Offer
Shares to such other Consenting Stockholders at a price per share equal to the
Market Price as of the date of the First Offer Notice of Sale (which price
shall, unless otherwise agreed by the Converting Stockholder and the Consenting
Stockholders accepting such offer, be payable in cash). As used in this Section
7.03, the "Qualifying First Offer Amount" means, with respect to any First Offer
Notice of Sale, the amount, if any, by which the number of First Offer Shares
specified in such First Offer Notice of Sale exceeds [*] percent of the number
of shares of the Company Common Stock outstanding at the time such First Offer
Notice of Sale is delivered (or such lesser amount as may be specified in the
First Offer Notice of Sale or as may otherwise be agreed to by the Converting
Stockholder).

               (i) If a Consenting Stockholder desires to accept all or any
          portion of the offer set forth in a First Offer Notice of Sale, such
          Consenting Stockholder (a "First Offer Electing Stockholder") shall,
          within ten Business Days of receipt of such First Offer Notice of
          Sale, notify the Converting Stockholder of its intention to acquire
          First Offer Shares and the number of such shares it desires to
          acquire, and deliver a copy of such notice to each other Consenting
          Stockholder.

               (ii) If, after giving effect to any amendment to any First Offer
          Electing Stockholder's notice pursuant to Section 7.03(a)(iii), the
          First Offer Electing Stockholders desire to acquire, in the aggregate,
          either (x) all the First Offer Shares, or (y) a number of First Offer
          Shares that is not more than the Qualifying First Offer Amount, then
          the First Offer Electing Stockholders shall have the right to acquire,
          in the case of clause (x), all the First Offer Shares or, in the case
          of clause (y), the number of shares that the First Offer Electing
          Stockholders desire to acquire (such shares that the First Offer
          Electing Stockholders have the right to acquire, the "Allocable First

          manner as the First Offer Electing Stockholders may agree):

                    (A) the Allocable First Offer Shares shall be allocated
               among the First Offer Electing Stockholders pro rata (based on
               the number of shares of Series B Stock owned by each of them)
               until all of the Allocable First Offer Shares have been allocated
               or any First Offer Electing Stockholder has been allocated the
               number of First Offer Shares that it desires to acquire, as
               specified in its notice to the Converting Stockholder, as it may
               have been amended pursuant to Section 7.03(a)(iii);

                    (B) if all Allocable First Offer Shares are not allocated

               Shares that it desires to acquire, as specified in its notice to
               the Converting Stockholder, as it may have been amended pursuant
               to Section 7.03(a)(iii)) pro rata (based on the number of shares

               Electing Stockholder shall have the right, by written notice sent
               to the Converting Stockholder (with a copy of such notice to each
               other Consenting Stockholder) within five days after its receipt
               of the notice from the Converting Stockholder pursuant to this
               Section 7.03(a)(iii) to amend the notice it delivered pursuant to
               7.03(a)(i) to increase or decrease the number of First Offer
               Shares that it desires to purchase;

                    (B) notwithstanding Section 7.03(a)(iii)(A), no notice by
               any First Offer Electing Stockholder pursuant to this Section
               7.03(a)(iii) shall constitute an amendment of the notice it
               delivered pursuant to Section 7.03(a)(i) if the number of shares
               that the First Offer Electing Stockholders originally desired to
               acquire, in the aggregate, as specified in their notices pursuant
               to Section 7.03(a)(i) was less than or equal to the Qualifying
               First Offer Amount and the number of shares that the First Offer
               Electing Stockholders subsequently desired to acquire, in the
               aggregate, as specified in their notices as proposed to be
               amended pursuant to this Section 7.03(a)(iii), was greater than
               the Qualifying First Offer Amount but less than all the First
               Offer Shares; if this Section 7.03(a)(iii)(B) applies, the First
               Offer Electing Stockholders shall have the right to acquire the
               number of shares that the First Offer Electing Stockholders
               originally desired to acquire, allocated among them in accordance
               with Section 7.03(a)(ii);

                    (C) if, after giving effect to any amendment to any First
               Offer Electing Stockholder's notice pursuant to this Section
               7.03(a)(iii), the First Offer Electing Stockholders desire to
               acquire, in the aggregate, either (x) all the First Offer Shares,
               or (y) a number of First Offer Shares that is not

               more than the Qualifying First Offer Amount, then the First Offer
               Electing Stockholders shall have the right to acquire, in the
               case of clause (x), all the First Offer Shares or, in the case of
               clause (y), the number of shares that the First Offer Electing
               Stockholders desire to acquire, allocated among them in
               accordance with Section 7.03(a)(ii);

                    (D) if, after giving effect to any amendment to any First
               Offer Electing Stockholder's notice pursuant to this Section
               7.03(a)(iii) (but subject to Section 7.03(a)(iii)(B)), the First
               Offer Electing Stockholders desire to acquire, in the aggregate,
               a number of First Offer Shares that is greater than the
               Qualifying First Offer Amount but less than all the First Offer
               Shares, then the Converting Stockholder's offer of the First
               Offer Shares shall be deemed rejected in full as of the last day
               for a First Offer Electing Stockholder to amend its notice
               pursuant to this Section 7.03(a)(iii); and

                    (E) if, after giving effect to any amendment to any First
               Offer Electing Stockholder's notice pursuant to this Section
               7.03(a)(iii), the First Offer Electing Stockholders desire to
               acquire, in the aggregate, a number of First Offer Shares that is
               less than or equal to the Qualifying First Offer Amount, then the
               Converting Stockholder's offer of the First Offer Shares shall be
               deemed accepted as to the number of First Offer Shares that the
               First Offer Electing Stockholders desire to acquire (and the
               First Offer Electing Stockholders shall have the right to acquire
               such shares as provided in Section 7.03(a)(iii)(C)) and shall be
               deemed rejected with respect to that portion of the First Offer
               Shares that exceeds the number of First Offer Shares that the
               First Offer Electing Stockholders desire to acquire as of the
               last day for a First Offer Electing Stockholder to amend its
               notice pursuant to this Section 7.03(a)(iii).

          (b)  If (i) the Converting Stockholder's offer of the First Offer
Shares is rejected (in whole or in part) as provided in Section 7.03(a), or (ii)
the purchase of the First Offer Shares is not consummated within the period set
forth in Section 7.05(a)(iii) for any reason other than a breach by the
Converting Stockholder of any of its covenants, representations or warranties
that are a condition to consummation of such purchase, then, beginning on the
date that the Converting Stockholder's offer of the First Offer Shares is deemed
rejected or the day following the last day of the period set forth in Section
7.05(a)(iii), as applicable (such applicable date, the "Free-to-Convert Date"),
the Converting Stockholder shall have the right to convert the First Offer
Shares with respect to which the Converting Stockholder's offer was rejected or
the First Offer Shares that were not purchased within the period set forth in
Section 7.05(a)(iii), as applicable (such First Offer Shares, the "Free-to-
Convert Shares"), to shares of Series A Stock at any time prior to the later of
(i) the ninetieth day after the Free-to-Convert Date, or (ii) if prior to or
within ten Business Days after the Free-to-Convert Date the Converting
Stockholder either delivers a Demand Notice pursuant to Section 8.01 or submits
a written request in response to a 

                                       39

Company Notice pursuant to Section 8.01 with respect to the registration of the
shares of Series A Stock into which the Free-to-Convert Shares may be converted,
either (A) the date on which the registration statement filed by the Company
with respect to such shares of Series A Stock becomes effective or (B) the date
on which such registration statement is withdrawn, as applicable. If the
Converting Stockholder does not convert the Free-to-Convert Shares into shares
of Series A Stock during the applicable period, the procedure set forth above
with respect to the First Offer Notice of Sale shall be repeated with respect to
any subsequent proposed conversion of shares of Series B Stock to shares of
Series A Stock by the Converting Stockholder.

     SECTION 7.04.  Post-IPO Right of First Refusal.
                    -------------------------------

          (a) Following consummation of the Company's initial Public Offering,
if a Consenting Stockholder (a "Post-IPO Selling Stockholder") or its Parent
shall receive at any time a bona fide offer in writing, which the Post-IPO
Selling Stockholder or its Parent proposes to accept (a "Post-IPO Third Party
Offer"), from a third party (the "Post-IPO Third Party Offeror") to acquire all
or part of its shares of Series B Stock (the "Post-IPO First Refusal Shares") or
to effect an Indirect Transfer (in which case the "Post-IPO First Refusal
Shares" shall be all the shares of Series B Stock owned by the Post-IPO Selling
Stockholder), the Post-IPO Selling Stockholder shall deliver to each other
Consenting Stockholder (the "Post-IPO First Refusal Stockholders") a notice (a
"Post-IPO Notice of Sale" and, together with the First Refusal Notice of Sale
and the First Offer Notice of Sale, the "Notices of Sale") containing a copy of
the Post-IPO Third Party Offer, the identity of the Post-IPO Third Party Offeror
and its Parent and an offer to sell the Post-IPO First Refusal Shares to the
Post-IPO First Refusal Stockholders on the following terms:  (i) if the Post-IPO
Third Party Offer contemplates a purchase of the Post-IPO First Refusal Shares
by the Post-IPO Third Party Offeror for consideration consisting solely of cash,
then the Post-IPO Selling Stockholder's offer shall be to sell the Post-IPO
First Refusal Shares for cash in an amount equal to the purchase price specified
in, and otherwise on the terms and conditions contained in, the Post-IPO Third
Party Offer, and (ii) if the Post-IPO Third Party Offer contemplates an
acquisition of the Post-IPO First Refusal Shares by the Post-IPO Third Party
Offeror for consideration any portion of which is not cash or if the Post-IPO
Third Party Offer contemplates an Indirect Transfer, then the Post-IPO Selling
Stockholder's offer shall be to sell the Post-IPO First Refusal Shares for cash
in an amount equal to the fair market value of the noncash consideration or of
the Post-IPO First Refusal Shares, as applicable (as determined pursuant to
Section 7.02(c) as if the references therein to Selling Stockholder, First
Refusal Shares and First Refusal Notice of Sale referred to the Post-IPO Selling
Stockholder, Post-IPO First Refusal Shares and Post-IPO Notice of Sale,
respectively) and otherwise on the terms and conditions contained in the Post-
IPO Third Party Offer.  The Post-IPO Notice of Sale shall specify the price at
which the Post-IPO First Refusal Shares are offered, as provided in the
preceding sentence.  The Post-IPO First Refusal Stockholders shall enter into an
appropriate confidentiality agreement reasonably requested by the Post-IPO
Selling Stockholder with respect to the Post-IPO Third Party Offer.

<PAGE>
 
               (i)   If a Post-IPO First Refusal Stockholder desires to accept
          all or any portion of the offer set forth in a Post-IPO Notice of Sale
          as to any part of the Post-IPO First Refusal Shares, such Post-IPO
          First Refusal Stockholder (a "Post-IPO Electing Stockholder") shall,
          within ten Business Days of receipt of such Post-IPO Notice of Sale,
          notify the Post-IPO Selling Stockholder of its intention to acquire
          Post-IPO First Refusal Shares and the number of such shares it desires
          to acquire, and deliver a copy of such notice to each other Post-IPO
          First Refusal Stockholder.

               (ii)  If the Post-IPO Electing Stockholders desire to acquire, in
          the aggregate, all of the Post-IPO First Refusal Shares, then the
          Post-IPO Electing Stockholders shall have the right to acquire all the
          Post-IPO First Refusal Shares, allocated among them in the same manner
          as First Refusal Shares are allocated among First Refusal Electing
          Stockholders pursuant to Section 7.02(a)(ii).

               (iii) If the Post-IPO Electing Stockholders desire to acquire,
          in the aggregate, less than all of the Post-IPO First Refusal Shares,
          then the Post-IPO Selling Stockholder shall so notify the Post-IPO
          Electing Stockholders and the procedures set forth in Section
          7.02(a)(iii) shall be followed as if the references therein to the
          First Refusal Electing Stockholders, the Selling Stockholder and First
          Refusal Shares referred to the Post-IPO Electing Stockholders, the
          Post-IPO Selling Stockholder and the Post-IPO First Refusal Shares.
          If after giving effect to any amendment to any Post-IPO Electing
          Stockholder's notice pursuant to said procedures, the Post-IPO
          Electing Stockholders desire to acquire, in the aggregate, less than
          all of the Post-IPO First Refusal Shares, then the Post-IPO Selling
          Stockholder's offer shall be deemed rejected as of the last day for a
          Post-IPO Electing Stockholder to amend its notice pursuant to said
          procedures.

          (b) If (i) the Post-IPO Selling Stockholder's offer of the Post-IPO
First Refusal Shares is rejected as provided in Section 7.04(a), or (ii) the
purchase of the Post-IPO First Refusal Shares is not consummated within the
period set forth in Section 7.05(a)(iii) for any reason other than a breach by
the Post-IPO Selling Stockholder of any of its covenants, representations or
warranties that are a condition to consummation of such purchase, then the Post-
IPO Selling Stockholder shall have the right, at any time during the sixty-day
period beginning on the date that the Post-IPO Seller Stockholder's offer of the
Post-IPO First Refusal Shares is deemed rejected or the day following the last
day of the period set forth in Section 7.05(a)(iii), as applicable, to enter
into a binding agreement to sell all of the Post-IPO First Refusal Shares to the
Post-IPO Third Party Offeror, or to effect the Indirect Transfer contemplated by
the Post-IPO Third Party Offer, as applicable, in either case on terms and
conditions no less favorable in the aggregate to the Post-IPO Selling
Stockholder (and, in the case of an Indirect Transfer, its Parent) than those
set forth in the Post-IPO Third Party Offer, and thereafter (within the period
specified below in this Section 7.04(b)) to sell all of the Post-IPO First
Refusal Shares to the Post-IPO Third Party Offeror or effect the Indirect
Transfer, as applicable, pursuant to such agreement.  The Post-IPO Selling
Stockholder shall, as promptly as 

                                       41
<PAGE>
 
practicable and prior to the closing of such sale or Indirect Transfer, provide
to the Post-IPO First Refusal Stockholders a copy of the agreement for the sale
of the Post-IPO First Refusal Shares so as to permit the Post-IPO First Refusal
Stockholders to confirm for themselves that the terms and conditions of such
sale are not less favorable in the aggregate to the Post-IPO Selling Stockholder
(and, in the case of an Indirect Transfer, its Parent) than those set forth in
the Post-IPO Third Party Offer. If the Post-IPO Selling Stockholder does not
enter into such an agreement during such sixty-day period, or does not close the
sale thereunder within sixty days after execution of such an agreement (subject
to extension for a maximum of one hundred eighty additional days to the extent
required to obtain all required Governmental and Private Approvals), the
procedure set forth above with respect to the Post-IPO First Refusal Notice of
Sale shall be repeated with respect to any subsequent proposed sale, assignment
or other disposition of shares of Series B Stock by the Post-IPO Selling
Stockholder.

          (c) If the Post-IPO First Refusal Shares include a sufficient number
of shares of Series  B Stock so that the holder thereof after giving effect to
the acquisition of such shares would beneficially own at least 16% of the shares
of Series B Stock then outstanding (or such other percentage of Series B Stock
that would, in accordance with this Agreement as in effect at such time, entitle
the holder to elect at least one director of the Company), then the Post-IPO
Selling Stockholder shall have the right to sell to the Post-IPO Third Party
Offeror such shares of Series B Stock or permit the Indirect Transfer, as
applicable, without converting such shares to Series A Stock so long as (i) in
the case of a sale of the Post-IPO First Refusal Shares, the Post-IPO Third
Party Offeror assumes the obligations of the Post-IPO Selling Stockholder under
this Agreement with respect to such shares and becomes a party to this
Agreement, and (ii) in the case of an Indirect Transfer, the Post-IPO Third
Party Offeror, upon taking control of the Post-IPO Selling Stockholder, causes
the Post-IPO Selling Stockholder to confirm in writing the continuing validity
and effectiveness of its obligations under this Agreement.   If the Post-IPO
First Refusal Shares do not include such sufficient number of shares of Series B
Stock, or if the Post-IPO Third Party Offeror refuses to become a party to this
Agreement, then the Post-IPO Selling Stockholder shall, prior to transferring
the Post-IPO First Refusal Shares to the Post-IPO Third Party Offeror or
effecting the Indirect Transfer, as applicable, convert all shares of Series B
Stock included in the Post-IPO First Refusal Shares to Series A Stock and shall
not have the right to sell Series B Stock to the Post-IPO Third Party Offeror or
to permit the Indirect Transfer while the Post-IPO Selling Stockholder holds
shares of Series B Stock.  The conversion of shares of Series B Stock to Series
A Stock pursuant to the foregoing sentence shall not be subject to the
provisions of Section 7.03.  If the Post-IPO Third Party Offeror receives only
shares of Series A Stock, then it shall not be required to become a party to
this Agreement.

          (d) Before submitting a Post-IPO Notice of Sale pursuant to Section
7.04(a) in response to a Post-IPO Third Party Offer that contemplates (i) a sale
of the Post-IPO First Refusal Shares in conjunction with other assets, (ii) an
acquisition of the Post-IPO First Refusal Shares by the Post-IPO Third Party
Offeror for consideration any portion of which is not cash or (iii) an Indirect
Transfer, the Post-IPO  Selling Stockholder and the other Consenting
Stockholders shall cause (A) if the Post-IPO Third Party Offer contemplates a
sale of the Post-IPO First Refusal Shares in conjunction with other assets, the
total consideration specified in the 

                                       42
<PAGE>
 
Post-IPO Third Party Offer to be allocated between the Post-IPO First Refusal
Shares and such other assets, (B) if the Post-IPO Third Party Offer contemplates
an acquisition of the Post-IPO First Refusal Shares by the Post-IPO Third Party
Offeror for consideration any portion of which is not cash or if the Post-IPO
Third Party Offer contemplates an Indirect Transfer, the fair market value of
the noncash consideration or of the Post-IPO First Refusal Shares, as
applicable, to be determined, in each case pursuant to Section 7.02(c), as if
the references therein to the Selling Stockholder, the First Refusal Notice of
Sale, the Third Party Offer and the First Refusal Shares referred to the Post-
IPO Selling Stockholder, the Post-IPO Notice of Sale, the Post-IPO Third Party
Offer and the Post-IPO First Refusal Shares, respectively.

                    --------------------------------------------------------
7.03 and 7.04.

          (a) Any purchase and sale of the Company Common Stock pursuant to

          warrant that the buying Consenting Stockholders will receive good and
          valid title to the First Refusal Shares, Post-IPO First Refusal Shares
          or First Offer Shares, as applicable (the "Offered Shares"), free and

               required with respect to the transactions to be consummated at
               such closing shall have been obtained, to the extent the failure
               to obtain such Approvals would prevent the Converting
               Stockholder, the Selling Stockholder or the Post-IPO Selling
               Stockholder, as the case may be, from performing any of its
               material obligations under the transaction documents or would

          of the applicable offer, subject to extension for a maximum of one
          hundred eighty additional days to the extent required to obtain all

7.04, the Company agrees that, on reasonable notice following the delivery of a
Notice of Sale, at reasonable times and without interfering with the business or
operations of the Company, it will assist the Converting Stockholder, the
Selling Stockholder or the Post-IPO Selling Stockholder, as the case may be, in
obtaining all necessary consents to any disposition of the Offered Shares.

     SECTION 7.06.  Transferee Consenting Stockholders. A Consenting Stockholder
                    ----------------------------------
shall remain a Consenting Stockholder for so long as it owns any Series B Stock
regardless of the percentage of Series B Stock it may own from time to time. Any
transferee of a Consenting Stockholder required to become a party to this
Agreement pursuant to Section 7.01(a), 7.01(b), 7.02(b) or 7.04(c) shall become
a Consenting Stockholder by delivering to the Company (which shall promptly send
notice thereof to the Consenting Stockholders) a counterpart signature page to
this Agreement. No further action by the Company or the Consenting Stockholders
shall be required for such person to become a party to this Agreement. Following
any Indirect Transfer permitted by this Agreement, the Consenting Stockholder
with respect to which such Indirect Transfer has occurred shall confirm to the
other Consenting Stockholders in writing the continuing validity and
effectiveness of its obligations under this Agreement.

     SECTION 7.07.  Cooperation. Each Consenting Stockholder shall use
                    -----------
commercially reasonable efforts to cooperate with any transferring Consenting
Stockholder in 

                                       44
<PAGE>
 
connection with its efforts to transfer any interest in the Company Common Stock
in accordance with the provisions of this Article VII, including making
qualified personnel available for attending hearings and meetings respecting any
consents, approvals and authorizations required for such transfer and, at the
request of the transferring Consenting Stockholder, making all filings with, and
giving all notices to, third parties and Governmental Authorities that may be
necessary or reasonably required to be made or given by such of the Consenting
Stockholders in order to effect the contemplated transfers. Subject to the other
provisions of this Article, no Consenting Stockholder shall take any action to
delay, impair or impede the receipt of any required consents, approvals or
authorizations. "Commercially reasonable efforts" as used in this Article shall
not require any party to undertake extraordinary or unreasonable measures to
obtain any consents, approvals or other authorizations, including requiring such
party to make any material expenditures (other than normal filing fees or the
like) or to accept any material changes in the terms of the contract, license or
other instrument for which a consent, approval or authorization is sought.

     SECTION 7.08.  Buy-Sell Procedure.
                    ------------------

          (a) After the [*] of the date of this Agreement and prior to
consummation of the Company's initial Public Offering, the procedure set forth
in this Section 7.08 (the "Buy-Sell Procedure") may be initiated by a Consenting
Stockholder Group (the "Initiating Holder"), at its option, by giving notice to
the other Consenting Stockholder Group (the "Responding Holder") of its election
to initiate the Buy-Sell Procedure. Such notice shall include a statement of the
Initiating Holder's estimate of the value per share of the Company Common Stock
for the purposes of the Buy-Sell Procedures (the "Stated Value").

          (b) Within sixty days after receipt of the notice from the Initiating
Holder, the Responding Holder shall give written notice of its election either
to (i) purchase (or designate another Person to purchase) the Initiating
Holder's ownership interest in the Company, or (ii) sell the Responding Holder's
ownership interest in the Company.  If the Responding Holder elects to purchase
(or cause a designee to purchase) the Initiating Holder's ownership interest,
the Initiating Holder shall be obligated to sell the same and, if the Responding
Holder elects to sell its ownership interest, the Initiating Holder (or its
designee) shall be obligated to buy the same.  The purchase price for the
ownership interest to be sold shall be the amount determined by multiplying the
Stated Value by the number of shares of the Company Common Stock being sold.  In
addition, the applicable Consenting Stockholder (or its designee) that the
foregoing procedure establishes will be the purchaser (the "Purchaser") of the
ownership interest of the other Consenting Stockholder (the "Seller"), shall
also purchase any preferred stock of the Company held by the Seller for the
issue price thereof plus any accreted or accrued and unpaid dividends thereon,
and any debt of the Company held by the Seller for the issue price thereof plus
any accreted or accrued but unpaid interest thereon.

          (c) The closing of the purchase and sale of the Seller's ownership
interest shall be held at the principal executive offices of the Company at
10:00 a.m. local time on a Business Day selected by the Purchaser, which closing
date shall be as promptly as practicable, 

__________
[*] Confidential Treatment Requested.

                                       45
<PAGE>
 
and in any event within sixty days after the Responding Holder's notice of
election is given, subject to extension for a maximum of one hundred eighty
additional days to the extent required to obtain all required Governmental and
Private Approvals. The closing shall be subject to the conditions applicable to
the transfer of Offered Shares as contemplated by Section 7.05(a). At such
closing, the Seller shall transfer to the Purchaser the Seller's ownership
interest in the Company free and clear of all Liens (other than Permitted Liens)
and shall execute such documents as may be necessary to effectuate the sale.
Unless otherwise agreed by the Purchaser and Seller, the purchase price shall be
payable by wire transfer of same day funds or by certified or cashier's check
drawn to the order of the Seller, as specified by the Seller. If the Purchaser
fails to tender payment at the closing in the manner agreed by the parties or if
the closing fails to occur within the time period specified above for any reason
other than a breach by the Seller, then such failure shall constitute an
election by the Purchaser to sell its ownership interest in the Company and the
Purchaser shall then be bound to sell if the Seller, by notice given within five
days thereafter, requires it to do so. If the Seller timely gives such notice,
then the date by which the closing of the purchase and sale of the Purchaser's
ownership interest shall occur shall be calculated, in accordance herewith, from
the date such notice is given. If the Seller does not timely give such notice or
fails to consummate the purchase as provided above, then the Buy-Sell Procedure
shall be deemed not to have been initiated.

     SECTION 7.09.  Default.
                    -------

          (a) The Bankruptcy of a Consenting Stockholder or its Parent (or any
Subsidiary of such Parent through which such Parent beneficially owns its
interest in such Consenting Stockholder) prior to consummation of the Company's
initial Public Offering with respect to any Consenting Stockholder shall
constitute an "Event of Default" by such Consenting Stockholder (the "Defaulting
Holder") under this Agreement.


          (b) Upon the occurrence of any Event of Default with respect to any
Defaulting Holder, the other Consenting Stockholder Group, provided it includes
no Defaulting Holders (the "Nondefaulting Holder"), shall have the right
exercisable by written notice given to the Defaulting Holder at any time after
and during the continuance of such Event of Default, to cause the purchase of
the entire ownership interest (including debt and equity) of such Defaulting
Holder in the Company.  Such remedy shall, with respect to an Event of Default
referred to in Section 7.09(a), be in addition to all other rights or remedies
available to the Nondefaulting Holder, to any other party hereunder or to the
Company under this Agreement or under any other Operative Document or otherwise,
and all such remedies shall be cumulative and no such remedy shall be to the
exclusion of any other remedy.

          (c) In the event written notice (a "Buy-Out Notice") of election to
cause the purchase of the ownership interest of any Defaulting Holder (the
"Purchased Interest") is given by the Nondefaulting Holder pursuant to Section
7.09(b), then the Purchased Interest will be purchased by the Nondefaulting
Holder (the "Buyer").

                                       46
<PAGE>
 
          (d) The price (the "Buy-Out Price") to be paid by the Buyer for the
Purchased Interest will be determined as follows:  The Buyer and the Defaulting
Holder will mutually select a nationally recognized investment banking firm (an
"Investment Banking Firm") to act as the "Arbiter" under this Section 7.09(d).
If the Buyer and the Defaulting Holder have not selected an Investment Banking
Firm by 5:00 p.m. New York City time on the fifth Business Day after the date of
the Buy-Out Notice, then the Buyer and the Defaulting Holder will each select an
Investment Banking Firm at its own expense, and the two Investment Banking Firms
will mutually select a third Investment Banking Firm to act as the Arbiter;
                                                                           
provided, however, that, if by 5:00 p.m. New York City time on the tenth
- --------  -------                                                       
Business Day after the date of the Buy-Out Notice, either the Buyer or the
Defaulting Holder has selected such an Investment Banking Firm while the other
has not, then the Investment Banking Firm so selected will act as the Arbiter.
Once the Arbiter has been selected, the Buyer and the Defaulting Holder will
each submit to the Arbiter, within thirty days of such selection, a price for
the Purchased Interest. The Arbiter shall pick as the Buy-Out Price under this
Section 7.09(d) either the price submitted by the Buyer or the price submitted
by the Defaulting Holder, whichever price is, in the judgment of the Arbiter,
closer to the price that an unaffiliated third party willing and able to buy
would be willing to pay, and which a willing and able seller would be willing to
accept, for the Purchased Interest. Such determination of the Buy-Out Price by
the Arbiter will be final and binding on the Buyer and the Defaulting Holder.
The Buyer and the Defaulting Holder will each pay one-half of the fees and
expenses of the Arbiter. All other costs and expenses of such determination will
be borne by the party incurring such cost or expense.

          (e) The closing of any purchase of a Purchased Interest shall take
place at the principal executive offices of the Company at 10:00 a.m. local time
on a Business Day selected by the Buyer, which closing date shall be as promptly
as practicable, and in any event within sixty days following the determination
of the Buy-Out Price, subject to extension for a maximum of one hundred eighty
additional days to the extent required to obtain all necessary Governmental and
Private Approvals.  The closing shall be subject to the conditions applicable to
the transfer of Offered Shares as contemplated by Section 7.05(a).  At such
closing, the Defaulting Holder shall Transfer to the Buyer the Purchased
Interest, free and clear of all Liens (other than Permitted Liens), and shall
execute such documents as may be necessary to effectuate the sale.  Unless
otherwise agreed by the Buyer and the Defaulting Holder, the Buy-Out Price shall
be payable by wire transfer of same day funds or by certified or cashier's check
drawn to the order of the Defaulting Holder, as specified by the Defaulting
Holder.

          (f) In lieu of giving a Buy-Out Notice pursuant to Section 7.09(b),
the Nondefaulting Holder may elect, by written notice given to the Defaulting
Holder at any time during the continuance of such Event of Default to cause the
Company to be dissolved and its assets liquidated.  If such election is made by
the Nondefaulting Holder, the Defaulting Holder shall vote its shares of Company
Common Stock in favor of dissolution of the Company.  Such remedy shall, with
respect to an Event of Default referred to in Section 7.09(a)(i), be in addition
to all other rights or remedies available to the Nondefaulting Holder, to any
other party hereunder or to the Company under this Agreement or under any other
Operative Document or otherwise, 

                                       47
<PAGE>
 
and all such remedies shall be cumulative and no such remedy shall be to the
exclusion of any other remedy.

     SECTION 7.10.  [*]

          (a) If a [*] occurs with respect to the [*] prior to consummation of
the Company's initial Public Offering, the Changed Stockholder shall promptly
thereafter give written notice thereof (a "Change Notice") to the Unchanged
Stockholder. If, at the time of such [*] the Unchanged Stockholder owns less
than [*] of the outstanding shares of Series B Stock and the Changed Stockholder
owns [*] of the outstanding shares of Series B Stock, then in addition to the
consequences of such [*] set forth in Sections 6.02(b) and 6.07(b), the
Unchanged Stockholder shall have the right exercisable by written notice (a
"Purchase Notice") given to the Changed Stockholder within sixty days after
receipt of the Change Notice, to purchase that number of shares of Series B
Stock owned by the Changed Stockholder that when added to the number of shares
of Series B Stock owned by the Unchanged Stockholder will equal [*] of the
outstanding shares of Series B Stock (the "Excess Shares"). The purchase price
for the Excess Shares shall be an amount equal to the fair market value thereof.

          (b) The fair market value of the Excess Shares shall be the amount of
cash, determined by appraisal as provided below, that a willing buyer would pay,
and a willing Seller would accept, for the Excess Shares, neither being under
any compulsion to buy or sell and each having reasonable knowledge of all
relevant facts. The Unchanged Stockholder shall designate one appraiser in its
Purchase Notice and the Changed Stockholder shall designate the second appraiser
by notice given to the Unchanged Stockholder within ten Business Days after its
receipt of the Purchase Notice. If either Consenting Stockholder fails to
designate its appraiser in a timely manner as provided above, then the appraisal
of the Excess Shares shall be conducted by the single appraiser that was timely
selected.
 
          (c) Each appraiser shall submit its independent determination of the
fair market value of the Excess Shares within twenty days after the date on
which the last appraiser is retained (or would have been retained had a second
appraiser been selected). If the respective determinations of the fair market
value of the Excess Shares vary by less than [*] percent of the higher
determination, the fair market value of the Excess Shares shall be the average
of the two determinations. If the respective determinations vary by [*] percent
or more of the higher determination, the two appraisers shall promptly designate
a third appraiser to conduct such appraisal. The first two appraisers shall be
instructed not to, and no party to this Agreement or any Controlled Affiliate of
such party shall, provide any information to the third appraiser as to the
determinations of the first two appraisers or otherwise influence the third
appraiser's determination in any way. The third appraiser shall submit its
determination of the fair market value of the Excess Shares within twenty days
after the date on which the third appraiser is retained. If a third appraiser is
retained, the fair market value of the Excess Shares shall equal the average of
the two closest of the three determinations, except that if the difference
between the highest and middle determination is no more than [*] and no less
than [*] of the 

__________

                                       48
<PAGE>
 
difference between the middle and the lowest determinations, then the fair
market value of the Excess Shares shall equal the middle determination.

          (d) Any appraiser retained pursuant to this Section 7.10 shall meet
the requirements of Section 7.02(c)(iv).  The Changed Stockholder and the
Unchanged Stockholder shall  bear equally the fees and expenses of the
appraisers.

          (e) The purchase and sale of the Excess Shares shall take place at the
principal executive offices of the Company at 10:00 a.m. local time on a
Business Day selected by the Unchanged Stockholder, which closing date shall be
as promptly as practicable and in any event within sixty days following the
determination of the purchase price, subject to extension for a maximum of one
hundred eighty additional days to the extent required to obtain all necessary
Governmental and Private Approvals.  At such closing, the Changed Stockholder
shall Transfer to the Unchanged Stockholder the Excess Shares free and clear of
all Liens (other than Permitted Liens) and shall execute such documents as may
be necessary to effectuate the sale.  Unless otherwise agreed by the Unchanged
Stockholder and the Changed Stockholder, the purchase price shall be payable by
wire transfer of same day funds or by certified or cashier's check drawn to the
order of the Changed Stockholder, as specified by the Changed Stockholder.

          (f) No vote or consent of the stockholders of the Company for a
Significant Stockholder Transaction shall be solicited, taken or given by the
Changed Stockholder during the period following a Change of Control that the
Unchanged Stockholder shall have the right to give a Purchase Notice or, if a
Purchase Notice is given, prior to the purchase by the Unchanged Stockholder of
the Excess Shares or the expiration of the period during which such purchase may
be consummated in accordance with this Section 7.10 provided that the period
shall be extended if failure to consummate the purchase of the Excess Shares is
a result of a breach by the Changed Stockholder.

     SECTION 7.11  Dissolution.
                   -----------

          (a) Prior to the [*] of consummation of the [*] and the [*] of the
date of this Agreement, no dissolution of the Company and liquidation of its
assets shall occur, except (i) in the sole discretion of [*] pursuant to Section
[*], (ii) with the consent of [*] in each case for so long as a Controlled
Affiliate of such Person is a Consenting Stockholder and has the right to
designate at least one director of the Company, and (iii) in the event of the
Bankruptcy of the Company. Each Consenting Stockholder hereby waives its right
to, and covenants and agrees not to, seek a judicial dissolution of the Company,
except as permitted by the preceding sentence.

          (b) In the event of a dissolution of the Company under the
circumstances described in Section 7.11(a), [*] and its Affiliates shall
have no right to the [*] the [*] or the [*] and [*] and its
Affiliates shall have no right to the [*] or the [*]. The rights of [*] and its
Subsidiaries, [*] and its Subsidiaries and [*] to [*] and, in the case of
[*], a [*]

[*] shall be paid in the following order of priority (as among the [*] and
subject to any prior rights of other creditors of the Company ) from revenues
collected by the Company under its agreements with [*] in connection with the
winding up of its affairs, after payment of operating expenses: first, to [*]
for the payment of its [*], second to [*] for the payment of its [*], third to
[*] for the payment of its [*] and fourth to [*] for its [*]. The payment of the
foregoing amounts shall be made before any distribution of liquidation proceeds
is made to holders of Company Common Stock in their capacity as common
stockholders.

          (c) Except as provided in Section 7.11(d), in the event of a
dissolution of the Company, [*] and [*] shall each own an undivided one-
half interest, without the obligation of accounting to the other, in the [*] 
[*] or [*].

          (d) In the event of a dissolution of the Company, [*] and [*] shall
form an [*] committee to supervise the procurement and maintenance of [*] and
other [*] developed, owned or otherwise controlled by the Company. The [*]
committee shall consist of four persons, two to be selected by [*] and two to be
selected by [*]. [*] and [*] agree, following the dissolution of the Company, to
equally divide the costs associated with procuring and maintaining [*] [*] and
other [*] developed, owned or otherwise controlled by the Company, and shall
each own an undivided one-half interest in such property. In the event that
either [*] or [*] elect not to pay one-half of the costs associated with
procuring or maintaining a particular [*] hereunder (for example, each [*] and
[*] [*] and [*] constituting a separate [*] for purposes of this provision),
such refusal shall act as a forfeiture by the non-paying party of any interest
it would otherwise have to the particular [*].

          (a)  Requests for Registration. At any time after the date which is
               -------------------------
six months after the closing of the Company's initial Public Offering, any
stockholder of the Company which is a party to this Agreement (an "Eligible
Holder") may request that the Company effect the registration under the
Securities Act of all or part of its shares of Series A Stock (including shares
of Series A Stock issuable upon conversion of shares of Series B Stock held by
it) for sale in the manner specified in such request. A stockholder that
previously owned shares of Series B

Stock but ceased to be a Consenting Stockholder upon the conversion of its
shares of Series B Stock to shares of Series A Stock shall continue to be a
party to this Agreement so long as it owns any shares of Series A Stock and
therefore shall be an Eligible Holder. Such request shall be made by furnishing
written notice thereof (a "Demand Notice") to the Company setting forth the
number of shares of Series A Stock requested to be registered and such Eligible
Holder's preferred method of distribution. Within ten days after receipt of any
Demand Notice, the Company shall give written notice of such Demand Notice to
all other Eligible Holders. Following receipt of notice from the Company of a
Demand Notice (the "Company Notice"), each such other Eligible Holder may give
the Company a written request to register any or all of such Eligible Holder's
Series A Stock (including shares of Series A Stock issuable upon conversion of
shares of Series B Stock held by it) in the registration described in the
Company Notice, provided that such written request is given within fifteen days
after the date on which the Company Notice is given (with such request stating
(i) the number of shares of Series A Stock to be so included, (ii) such other
Eligible Holder's preferred method of distribution of such shares and (iii) any
other information that the Company Notice reasonably requests be included in
such notice from such Eligible Holder). All registrations requested pursuant to
this Section 8.01 are referred to herein as "Demand Registrations." The Company
shall not be required to effect a Demand Registration unless the aggregate
number of shares of Series A Stock demanded to be so registered is at least [*]
percent of the number of shares of Company Common Stock then outstanding (the
"Minimum Condition"). If the Minimum Condition is met, then, subject to Sections
8.01(b), 8.01(c) and 8.01(f) below, the Company shall, as soon as practicable,
file with the SEC and use all commercially reasonable efforts to cause to become
effective as promptly as practicable, a registration statement on a form
applicable to the sale of securities to the general public which shall cover the
shares of Series A Stock requested to be registered pursuant to such Demand
Notices.

          (b) Number of Demand Registrations. Once a Demand Registration has
              ------------------------------
been effected, the Company shall not be obligated to register Series A Stock
pursuant to another Demand Registration prior to the expiration of twelve months
from the date on which the previous Demand Registration was declared effective;
provided, however, that a registration will not count as a Demand Registration
unless it has become effective, and such effectiveness has been maintained under
the Securities Act (and not subject to any stop order, injunction or other order
or requirement of the SEC or other Governmental Authority for any reason) for
the period specified in Section 8.03(a). Each Eligible Holder may, before any
registration statement becomes effective, withdraw its shares of Series A Stock
from inclusion therein if the terms of the proposed distribution are not
satisfactory to such Eligible Holder. If after giving effect to such withdrawal
or withdrawals of shares from a Demand Registration the Minimum Condition would
no longer be satisfied, then such registration statement shall be withdrawn. A
registration that is withdrawn at the request of the Eligible Holders that
demanded such Demand Registration will not count as a Demand Registration.

          (c) Restrictions on Registrations. The Company may postpone for up to
              ----------------------------- 
three months after its receipt of a Demand Notice the filing of a registration
statement for a Demand Registration if the Company reasonably believes that such
Demand Registration would have a

                                       51

material adverse effect on any proposal or plan by the Company or any of its
Subsidiaries to engage in any financing, acquisition of assets (other than in
the ordinary course of business) or any merger, consolidation, tender offer or
other significant transaction and notifies the Eligible Holders in writing of
such postponement; provided that the Company shall have the right to so postpone
                   --------
such filing or effectiveness only one time during any period of twelve
consecutive months; and provided, further, that the three-month limitation
                        --------  -------
contained above in this Section 8.01(c) and the limitation contained in the
first proviso to this Section 8.01(c) shall not apply if the shares proposed to
be registered by the Eligible Holder furnishing the applicable Demand Notice
could then be sold without restrictions (including any volume limitation) under
the Securities Act.



          (d)  Underwriting.
               ------------

               (i)  Subject to Section 8.01(e), the distribution of the Series A
          Stock covered by the Demand Registration shall be effected by means of
          a firm commitment underwriting, and the right of any Eligible Holder
          to registration pursuant to this Article VIII shall be conditioned
          upon such Eligible Holders' participation in such underwriting and the
          inclusion of such Eligible Holder's Series A Stock in the underwriting
          (unless otherwise mutually agreed by a majority in interest of the
          other Eligible Holders) to the extent provided herein.  The Company
          (together with all Eligible Holders proposing to distribute their
          Series A Stock through such underwriting) shall enter into an
          underwriting agreement in customary form with a managing underwriter
          of nationally recognized standing selected for such underwriting by
          the Company with the approval of the Eligible Holder that has included
          the largest number of shares in the Demand Registration, such approval
          not to be withheld unreasonably.  No Eligible Holder may participate
          in any Demand Registration unless such Eligible Holder (A) agrees to
          sell its Series A Stock on the basis provided in such underwriting
          agreement and (B) completes and executes all questionnaires, powers of
          attorney, indemnities and other documents required under the terms of
          such underwriting agreement.

               (ii) Notwithstanding any other provision of this Article VIII, if
          the managing underwriter advises the Company and the Eligible Holders
          in writing that marketing factors require a limitation of the number
          of shares to be underwritten, then the managing underwriter may
          exclude shares requested to be included in such Demand Registration.
          The number of shares of Series A Stock that may be included in the
          Demand Registration and underwriting shall be allocated among the
          Eligible Holders who have requested registration in accordance with
          the provisions of Section 8.01(f).  No Series A Stock excluded from
          the underwriting by reason of the managing underwriter's marketing
          limitation shall be included in such Demand Registration.

                                       52
<PAGE>
 
               (iii)  If any Eligible Holder participating in a Demand
          Registration disapproves of the terms of the underwriting, such person
          may elect to withdraw therefrom by written notice to the Company, the
          managing underwriter and the other Eligible Holders.  If by such
          withdrawal a greater number of shares of Series A Stock held by other
          Eligible Holders may be included in such Demand Registration (up to
          the maximum of any limitation imposed by the managing underwriter),
          then the Company shall offer to all Eligible Holders participating in
          the Demand Registration the right to include additional shares of
          Series A Stock, which additional shares shall be allocated among the
          Eligible Holders who have requested registration in accordance with
          the provisions of Section 8.01(f).

          (e) Shelf Registration. If at the time of a Demand Notice, the Company
              ------------------
is eligible to file a registration statement on Form S-3 (or any equivalent
successor form), then Eligible Holders who hold at least 51% of the shares of
Series A Stock which are to be included in a Demand Registration may request
that the Demand Registration be effected pursuant to a shelf registration under
Rule 415 of the Securities Act; provided, however, that (i) if the Company shall
                                -----------------
reasonably determine, after consultation with an independent investment banking
firm of nationally recognized standing, that such method of distribution would
adversely affect the public market for the Series A Stock, then the Company
shall not be obligated to effect the Demand Registration pursuant to such method
of distribution, and (ii) during the term of any such shelf registration, the
Company may require from time to time that the Eligible Holders refrain from
selling pursuant to such registration statement under the circumstances, in the
manner and for the time period described in Section 8.01(c).

          (f) Allocation among Eligible Holders. If the managing underwriter
              ---------------------------------
imposes a limit on the number of shares of Series A Stock to be included in the
Demand Registration, then each Eligible Holder shall have the right to include
in such Demand Registration up to its pro rata share (based on the ratio that
the number of shares of Series A Stock proposed to be sold by it bears to the
total number of shares of Series A Stock proposed to be sold by all Eligible
Holders who have elected to participate in the Demand Registration) of the
maximum number of shares permitted by the managing underwriter to be included in
the Demand Registration (the "Maximum Amount").

          (g) Inclusion of Shares by the Company. If the managing underwriter
              ----------------------------------
has not limited the number of shares of Series A Stock to be underwritten or if
the number of shares which the Eligible Holders have requested to be registered
is less than the Maximum Amount, then the Company may include securities for its
own account or for the account of others in such Demand Registration if the
managing underwriter so agrees and if the number of shares of Series A Stock
held by Eligible Holders which would otherwise have been included in such Demand
Registration and underwriting will not thereby be limited. The inclusion of such
shares shall be on the same terms as the registration of shares held by the
Eligible Holders. In the event that the managing underwriter excludes some of
the securities to be registered, the securities to be sold for the account of
the Company and any other holders shall be excluded in their entirety prior to
the exclusion of any shares of Series A Stock of the Eligible Holders.

     SECTION 8.02. Lockup Agreements. Each Eligible Holder agrees not to effect
                   -----------------
any public sale or other distribution of Series A Stock during the seven days
prior to the effective date of any Public Offering or Demand Registration or
during the 180-day period (or such shorter period as the managing underwriter
may require) beginning on such effective date (except in either case as part of
such Demand Registration), unless the managing underwriter otherwise agrees. The
Company agrees not to effect any public sale or other distribution of Series A
Stock during the seven days prior to the effective date of any Demand
Registration or during the 180-day period (or such shorter period as the
managing underwriter may require) beginning on such effective date (except in
either case as part of such Demand Registration or pursuant to registrations on
Form S-8 or any successor form), unless the managing underwriter otherwise
agrees. Each Eligible Holder understands that stop transfer instructions may be
given to the Company's transfer agent to prevent transfers restricted by this
Section 8.02 during the applicable period of such restriction.

     SECTION 8.03. Registration Procedures. Whenever the Company is obligated by

possible:

          (a) prepare and file with the SEC a registration statement with
respect to such shares and use all commercially reasonable efforts to cause such

          (b) prepare and file with the SEC 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 until the sooner

effective date of such registration statement and comply with the provisions of
the Securities 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 Eligible Holder participating in such Demand
Registration and the underwriters such number of copies of such registration
statement, each amendment and supplement thereto, the prospectus included in
such registration statement (including each preliminary prospectus) and such
other documents as such seller or underwriters may reasonably request in order
to facilitate the sale of the shares being sold;

          (d) use all reasonable efforts to register or qualify the shares being
sold under such other securities or blue sky laws of such jurisdictions as any
seller reasonably requests and do any and all other acts and things which may be
reasonably necessary or advisable to enable 

                                       54
<PAGE>
 
such seller to consummate the disposition in such jurisdictions of the shares
owned by such seller; provided, however, 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 subparagraph, (ii) conform its
capitalization or the composition of its assets to the securities or blue sky
laws of such jurisdictions or (iii) consent to general service of process in any
such jurisdiction;

          (e) cause all such shares to be listed or authorized for quotation on
each securities exchange or automated quotation system on which similar
securities issued by the Company are then listed or quoted;

          (f) notify each seller of such shares, promptly after it shall receive
notice thereof, of the time when such registration statement has become
effective or a supplement to any prospectus forming a part of such registration
statement has been filed;

          (g) notify each seller of such shares of any request by the SEC for
the amending or supplementing of such registration statement or prospectus or
for additional information;

          (h) prepare and file with the SEC, promptly upon the request of any
seller of such shares, any amendments or supplements to such registration
statement or prospectus which, in the opinion of counsel selected by the holders
of a majority of the shares being registered, is required under the Securities
Act in connection with the distribution of shares by such seller;

          (i) prepare and promptly file with the SEC each amendment or
supplement to such registration statement or prospectus as may be necessary to
correct any statements or omissions if, at the time when a prospectus relating
to such securities is required to be delivered under the Securities Act, any
event shall have occurred as the result of which any such prospectus or any
other prospectus as then in effect would include an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances in which they were made,
not misleading; and

          (j) advise each seller of such shares, promptly after it shall receive
notice or obtain knowledge thereof, of the issuance of any stop order by the SEC
suspending the effectiveness of such registration statement or the initiation or
threatening of any proceeding for such purpose and promptly use commercially
reasonable efforts to prevent the issuance of any stop order or to obtain its
withdrawal if such stop order should be issued.

     SECTION 8.04. Expenses. Each Eligible Holder that participates in a Demand
                   --------
Registration (including a Demand Registration that is withdrawn prior to
becoming effective) shall pay all underwriting discounts and commissions and any
transfer taxes attributable to the sale of such Eligible Holder's shares, the
fees and expenses of counsel for such Eligible Holder, and any other out-of-
pocket expenses of such Eligible Holder incurred in connection with its
participation in such Demand Registration. The Company shall pay all expenses
connected with 

                                       55
<PAGE>
 
the registration of such shares for sale, including the registration fee, the
fees of its counsel and accountants and any printing costs.


     SECTION 8.05. Preparation of Registration Statement. Each Eligible Holder
                   ------------------------------------- 
agrees to furnish to the Company such written information concerning such
Eligible Holder as may reasonably be requested by the Company which is necessary
in connection with any Demand Registration.


     SECTION 8.06.  Indemnification.
                    ---------------

          (a) In the event that the Company effects a registration of any shares
owned by an Eligible Holder, such Eligible Holder shall indemnify and hold the
Company, and each of its directors and officers and each person, if any, who
controls the Company within the meaning of the federal securities laws (the
"Company Indemnified Parties") harmless against all losses, liabilities and
expenses of any nature whatsoever which the Company Indemnified Parties may
incur as a result of or arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in the registration
statement filed by the Company (including any prospectus contained in such
registration statement and any post-effective amendment or supplement thereto)
or as a result of or arising out of or based upon the omission or alleged
omission to state therein a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, which untrue statement or omission or alleged untrue
statement or omission was made in such registration statement (including any
prospectus contained in such registration statement and any post-effective
amendment or supplement thereto) in reliance upon and in conformity with
information furnished in writing by or behalf of such Eligible Holder for
inclusion therein; provided, however, that such Eligible Holder shall not be
                   --------  -------                                        
liable to the extent that the losses, liabilities or expenses arise out of or
are based upon (i) the use by the Company or another Eligible Holder of any
prospectus after such time as the obligation of the Company to keep the same
effective and current has expired or (ii) the use by the Company or another
Eligible Holder of any prospectus after such time as such Eligible Holder has
advised the Company that the filing of a post-effective amendment or supplement
thereto is required with respect to any information contained in such prospectus
concerning such Eligible Holder, except such prospectus as so amended or
supplemented.

          (b) In the event that the Company effects a registration of any shares
owned by an Eligible Holder, the Company shall indemnify and hold such Eligible
Holder, and each of its directors and officers and each person, if any, who
controls the Eligible Holder within the meaning of the federal securities laws
(the "Stockholder Indemnified Parties") harmless against all losses, liabilities
and expenses of any nature whatsoever which such Stockholder Indemnified Parties
may incur as a result of or arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in the registration
statement filed by the Company (including any prospectus contained in such
registration statement and any post-effective amendment or supplement thereto)
or as a result of or arising out of or based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary in 

                                       56
<PAGE>
 
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, provided, however, that the Company will
                                      --------  -------
not be liable in any such case to the extent that the losses, liabilities or
expenses arise out of or are based upon (i) any untrue statement or omission or
alleged untrue statement or omission made in such registration statement
(including any prospectus contained in such registration statement and any post-
effective amendment or supplement thereto) in reliance upon and in conformity
with information furnished in writing by or on behalf of such Eligible Holder to
the Company for inclusion therein in connection therewith, (ii) the use of any
prospectus after such time as the obligation of the Company to keep the same
effective and current has expired, or (iii) the use of any prospectus after such
time as the Company has advised the Eligible Holder that the filing of a post-
effective amendment or supplement thereto is required, except such prospectus as
so amended or supplemented.

          (c) With respect to the indemnities provided above in this Section
8.06, an indemnified party shall, with respect to any claim made against such
indemnified party, notify the indemnifying party in writing of the nature of the
claim as soon as practicable but not more than ten days after the indemnified
party shall have received notice of the assertion thereof before any court or
governmental authority.  The failure by an indemnified party to give notice as
provided in the foregoing sentence shall not relieve the indemnifying party of
its obligations under this section except to the extent that the failure results
in the failure of actual notice to the indemnifying party and the indemnifying
party is damaged solely as a result of the failure to give notice.  Upon receipt
of notice by an indemnifying party from an indemnified party of the assertion of
any such claim, the indemnifying party shall employ counsel reasonably
acceptable to the indemnified party and shall assume the defense of such claim.
The indemnified party shall have the right to employ separate counsel and to
participate in (but not control) any such action, but the fees and expenses of
such counsel shall be the expense of such indemnified party unless (i) the
employment of counsel by such indemnified party has been authorized by the
indemnifying party, (ii) the indemnified party shall have been advised by its
counsel in writing that there is a conflict of interest between the indemnifying
party and the indemnified party in the conduct of the defense of such action (in
which case the indemnifying party shall not have the right to direct the defense
of such action on behalf of the indemnified party) or (iii) the indemnifying
party shall not in fact have employed counsel to assume the defense of such
action, in each of which cases the fees and expenses of such counsel shall be at
the expense of the indemnifying party.  An indemnifying party shall not be
liable for any settlement of an action effected without its written consent
(which consent shall not be unreasonably withheld).  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
action.

payment by the Company to the [*] and (2) the [*] being in form and substance
mutually agreed upon by the parties, but including at least the following terms:

     In the event the [*] exercises its [*] under this Section 10.08 and
following such exercise [*]. Losses means any cost, damage (including, without
limitation, any consequential, special or punitive damages), including, but not
limited to, loss of revenue or income, or loss of business reputation,
disbursement, expense, liability, loss, deficiency, obligation, penalty, or
settlement of any kind or nature, whether forseeable or unforseeable, including,
but not limited to, out of pocket interest or other carrying cost, penalties,
legal, accounting and other professional fees and expenses incurred in the
investigation, collection, prosecution and defense of claims, and amounts paid

advances, for all losses incurred or suffered by [*]. Upon the initiation of any
such legal action, all restrictions on competition imposed by this Agreement on

indemnified party shall have received notice of the assertion thereof before any
court or governmental authority.  The failure by an indemnified party to give
notice as provided in the foregoing sentence shall not relieve the indemnifying
party of its obligations under this section except to the extent that the
failure results in the failure of actual notice to the indemnifying party and
the indemnifying party is damaged solely as a result of the failure to give
notice.  Upon receipt of notice by an indemnifying party from an indemnified
party of the

assertion of any such claim, the indemnifying party shall employ counsel
reasonably acceptable to the indemnified party and shall assume the defense of
such claim. The indemnified party shall have the right to employ separate
counsel and to participate in any such action, but the fees and expenses of such
counsel shall be the expense of such indemnified party unless (i) the employment
of counsel by such indemnified party has been authorized by the indemnifying
party, (ii) the indemnified party shall have been advised by its counsel in
writing that there is a conflict of interest between the indemnifying party and
the indemnified party in the conduct of the defense of such action (in which
case the indemnifying party shall not have the right to direct the defense of
such action on behalf of the indemnified party) or (iii) the indemnifying party
shall not in fact have employed counsel to assume the defense of such action, in
each of which cases the fees and expenses of such counsel shall be at the
expense of the indemnifying party. An indemnifying party shall not be liable for
any settlement of an action effected without its written consent (which consent
shall not be unreasonably withheld). 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 action.

subscribed for all and not less than all of its Pro Rata Share of such
Additional Capital (the "Funding Stockholders") and each such Funding
Stockholder shall have the right to subscribe for all or any of such Unfunded
Amount on terms no more favorable to the offeree then those set forth in the

Stockholders so subscribing in proportion to their respective Pro Rata Shares up

applicable Funding Stockholder). None of the Consenting Stockholders,
Participants or the Company shall have any duty to limit the dilution of
economic or voting interests in the Company of Consenting Stockholders not
subscribing for their Pro Rata Share of Additional Capital. The subscription
rights of the Consenting Stockholders pursuant to this Section 11.02 shall not
apply to shares of Series A Stock or options or warrants to purchase shares of

Company or to [*] or any of its Subsidiaries, in each case as contemplated by
the exception to the requirements of clause (b)(ii) of the definition of

     SECTION 12.06  Severability.  If any provision of this Agreement shall be 
                    ------------
held to be illegal, invalid or unenforceable, that provision will be enforced to
the maximum extent permissible so as to effect the intent of the parties, and
the validity, legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby. If necessary to effect the intent of
the parties, the parties will negotiate in good faith to amend this Agreement to
replace the unenforceable language with enforceable language which as closely as
possible reflects such intent.

     SECTION 12.07  Amendments and Waivers. This Agreement may not be amended
                    ----------------------
or modified in any respect except by an instrument in writing signed by all of
the parties hereto. Any failure of any party hereto to comply with any
obligation, covenant, agreement or condition contained herein may be waived by
the party or parties entitled to the benefits thereof, but such waiver or
failure to insist upon strict compliance with such obligation, covenant,
agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure.

     SECTION 12.08  Counterparts.  This Agreement may be executed in one or more
                    ------------
counterparts, all of which shall be considered one and the same agreement, and
shall become effective when one or more counterparts shall have been signed by
each party and delivered to each other party.

     SECTION 12.09  Entire Agreement.  The provision of this Agreement and the 
                    ----------------
other Operative Documents set forth the entire agreement and understanding among
the parties as to the subject matter hereof and supersede all prior agreements,
oral or written, and other communications between the parties relating to the
subject matter hereof.

     SECTION 12.10  Assignment. No party shall assign this Agreement or any of
                    ----------
its rights or obligations hereunder without the prior written consent of the

operation of law in connection with a merger or consolidation of such party
(without prejudice to any other rights the parties may have under Section 7.02,

     SECTION 12.11  No Third-Party Beneficiaries. This Agreement is for the sole
                    ----------------------------
benefit of the parties and their permitted assigns and nothing herein expressed
or implied shall give or be construed to give to any Person, other than the

     SECTION 12.12  Expenses.
                    --------

          (a) Whether or not any of the Transactions are consummated, all costs
and expenses incurred in connection with the [*] and the Transactions shall be
paid by the party incurring such cost or expense, except as the parties shall
otherwise agree.

          (b) The provisions of this Section 12.12 shall remain operative and in
full force and effect regardless of the expiration of this Agreement or the
consummation of the Transactions.

     SECTION 12.13  Remedies
                    --------

          (a) In no event will any party be liable to another party for
incidental damages, lost profits, lost savings, or any other consequential or
punitive damages, even if such party has been advised of the possibility of such
damages, resulting from the breach of its obligations under any [*] or from the
use of any confidential or other information.

          (b) Because the breach by any party of the provisions of Article VI,
Article VII and Section 10.05 would cause irreparable harm and significant
injury that would be difficult to ascertain and would not be compensable by
damages alone, the parties agree that each party will have the right to enforce
such provisions by injunction, specific performance or other equitable relief
without prejudice to any other rights and remedies the enforcing party may have.
The reference to specific Sections or Articles  in this Section 12.13(b) is not
a waiver of any party's rights to seek equitable relief for breaches of other
Sections or Articles.

          (c) No failure or delay of any party in exercising any power or right
under this Agreement shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such right or power, preclude any other or
further exercise thereof or the exercise of any other right or power.

     SECTION 12.14   Publicity. No public release, announcement or other form 
                     ---------
of publicity concerning the Transactions shall be issued by any party without

may be required by Law or the rules or regulations of any securities exchange or
association, in which case the party required to make the release or
announcement shall, to the extent possible, allow the other party reasonable
time to comment on such release or announcement in advance of such issuance.

all other acts that may be reasonably necessary or desirable to give effect to
the Transactions or the exercise by the other parties of their respective rights
hereunder.

     SECTION 12.16  Jurisdiction; Consent to Service of Process
                    -------------------------------------------

          (a) Each party hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of any Delaware State
court sitting in the County of New Castle or any Federal court of the United
States of America sitting in the District of Delaware, and any appellate court
from any such court, in any suit, action or proceeding arising out of or
relating to this Agreement or any other Operative Document, or for recognition
or enforcement of any judgment, and each party hereby irrevocably and
unconditionally agrees that all claims in respect of any such suit, action or
proceeding may be heard and determined in such Delaware State court or, to the

fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or any other [*] in any Delaware
State court sitting in the County of New Castle or any Federal Court sitting in
the District of Delaware. Each party hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance
of such suit, action or proceeding in any such court and further waives the
right to object, with respect to such suit, action or proceeding, that such
court does not have jurisdiction over such party.

          (c) Each party irrevocably consents to service of process in the
manner provided for the giving of notices pursuant to this Agreement.  Nothing
in this Agreement shall affect the right of any party to this Agreement to serve
process in any other manner permitted by law.


     SECTION 12.17  Waiver of Jury Trial.  Each party waives, to the fullest 
                    --------------------
extent permitted by applicable law, any right it may have to a trial by jury in
respect of any action, suit or proceeding arising out of or relating to this
Agreement or any other Operative Document.

except (a) to the extent any of the foregoing is or becomes available to the
public other than as a result of disclosure by such Consenting Stockholder or
any of its Affiliates or the directors, officers, employees, agents, advisors
and controlling persons of it or any of its Affiliates, (b) as necessary to
effect a transaction under and in compliance with Article VII or VIII (c) as may
be required by law and (d) as any Consenting Stockholder may disclose to its
lenders, rating agencies and business, legal and financial advisors. In the
event any Consenting Stockholder is required by applicable law or regulation or
by legal process to disclose any of the foregoing, it will provide the Company
and the other Consenting Stockholders and any other parties hereto with prompt
notice thereof to enable them to seek an appropriate protective order. The
covenants made by a Consenting Stockholder and each other party hereto in this
Section 12.19 shall continue to apply for a period of two years after such
Consenting Stockholder ceases to be a Consenting Stockholder. In the event that

available filing, such Initial Participant shall notify the other Initial
Participant of such proposed filing and shall seek confidential treatment for
such portions of the filed documents as the parties shall agree prior to the

Exercise Price" and, together with the Initial Warrant Exercise Price, the

                                  SECTION IV

     4.1  Representations and Warranties of the Company; Certain Covenants.
          ---------------------------------------------------------------- 

          (a)  The Company represents and warrants to each of the Registered
Holders that as of December 31, 1997:

               (i)  Organization and Standing.  The Company (x) is a corporation
                    -------------------------
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization and is duly qualified or licensed to do
business and in good standing in each jurisdiction in which the failure to be so
qualified or licensed and in good standing (individually or in the aggregate)
would have a material adverse effect on the Company, and (y) has all requisite
corporate power and authority necessary to enable it to carry on its business as
now conducted, to enter into this Agreement, to issue the Warrants and to carry
out the transactions contemplated hereby and thereby. True and accurate copies
of the Company's Amended and Restated Articles of Association and Amended and
Restated Memorandum of Association, each as amended and as currently in effect,
have been made available to the Initial Registered Holders through the Company's
filings with the SEC pursuant to the Securities Exchange Act of 1934, as amended
(the "Exchange Act") prior to December 31, 1997, and such documents constitute
all of the constitutive or governing documents of the Company.

               (ii) Capitalization.  The authorized capital of the Company is,
                    --------------
as of the date hereof, and will be, as of the Effective Date, $5,500,000,
consisting of one class and series of Ordinary Shares divided into 500,000,000
shares of $.01 par value, and one class and series of Preference Shares divided
into 50,000,000 shares of $.01 par value ("Preference Shares"). The rights,
privileges and preferences of the Ordinary Shares and Preference Shares are as
stated in the Company's Amended and Restated Memorandum of Association. As of
December 31, 1997, there were issued and outstanding 48,228,588 Ordinary Shares,
no Preference Shares and no other shares of capital stock. All such issued and
outstanding Ordinary Shares and Preference Shares have been duly authorized and
validly issued, are fully paid and nonassessable, and were issued in compliance
with all applicable state and federal securities laws. As of December 31, 1997,
there were no outstanding options, warrants or other rights to purchase or
otherwise acquire equity securities of the Company, securities convertible into
or exchangeable for equity securities of the Company, options, warrants or other
rights to purchase

or otherwise acquire any such convertible or exchangeable securities, or
agreements to issue or grant any of the foregoing (collectively, "Rights"),
other than those set forth on Schedule 4.1. Since December 31, 1997, the Company
has not issued any additional Ordinary Shares (except upon exercise of
outstanding Rights listed on Schedule 4.1), Preference Shares or other capital
stock and the Company has not issued or granted any Rights (except as set forth
on Schedule 4.1). All Rights listed on Schedule 4.1 have been duly authorized
and validly issued, are fully paid and nonassessable (except as to the payment
of any exercise price for the underlying securities) and were issued in
compliance with all applicable state and federal securities laws. To the best
knowledge of the Company, other than the Voting Agreement, there are no voting
trusts, voting agreements, irrevocable proxies or other agreements or
understandings with respect to any voting shares of capital stock of the
Company. The Company has reserved: (i) 9.1 million Ordinary Shares for issuance
to employees, officers, directors, consultants and agents of the Company
pursuant to any employee or consultant stock offering, plan or arrangement
approved by the Board of Directors of the Company (all of which are set forth on
Schedule 4.1) and (ii) and approximately 1.2 million Ordinary Shares for
issuance upon exercise of the Warrants. Except as set forth above in this
Section 4.1(a)(ii), no shares of capital stock or other securities of the
Company were issued, reserved for issuance or outstanding as of December 31,
1997. Other than the Rights listed on Schedule 4.1, there are no preemptive
rights, rights of first refusal, participation rights or other similar rights
currently outstanding or in effect to purchase any of the authorized but
unissued capital stock or treasury stock of the Company.

               (iii) Authorization.  All corporate action on the part of the
                     -------------
Company and its officers, directors and shareholders necessary for the
authorization, execution and delivery of, and the performance of all obligations
of the Company under, this Agreement and, upon issuance in accordance with the
terms of this Agreement, the Warrants, and for the authorization, issuance and
delivery of the Warrants and of the Shares issuable upon exercise of the
Warrants has been taken. This Agreement has been duly executed and delivered by
the Company, and this Agreement constitutes, and the Warrants when issued and
delivered in accordance with the terms of this Agreement shall constitute, the
legal, valid and binding obligations of the Company, enforceable against the
Company in accordance with their respective terms, subject to: (x) judicial
principles respecting election of remedies or limiting the availability of
specific performance, injunctive relief and other equitable remedies; and (y)
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect generally relating to or affecting creditors' rights.

               (iv)  No Conflicts.  The execution and delivery by the Company of
                     ------------
this Agreement and the Warrants and the performance by the Company of its
obligations hereunder and thereunder and the consummation of the transactions
contemplated hereby and thereby do not and will not conflict with, result in any
violation of or default (with or without notice or lapse of time or both) under,
give rise to a right of termination, cancellation or acceleration or any
material obligation or to the loss of any material benefit under or result in or
require the creation, imposition or extension of any lien, security interest,
restriction or other encumbrance upon any of the Company's properties or assets
(other than those imposed under this Agreement or the Warrants) under (i) any
oral or written contract, indenture, mortgage, lease, deed, commitment,
agreement, arrangement or legally binding understanding or instrument, (ii) any
provision of its constitutive or governing documents or (iii) any law, statute,
ordinance, rule,

                                       8
<PAGE>
 
regulation, judgment, order, decree or arbitral award, except for any such
conflicts, violations, defaults, rights, obligations or losses that,
individually or in the aggregate, would not have a material adverse effect on
the Company or its ability to consummate the transactions contemplated under
this Agreement or the Warrants.
 
               (v)  SEC Filings.  The Company has filed all required reports,
                    -----------
schedules, forms, statements and other documents with the SEC since December 31,
1996 (as such documents have been amended prior to the date hereof, the "Company
SEC Documents").  As of their respective dates, the Company SEC Documents
complied in all material respects with the requirements of the Securities Act of
1933, as amended (the "Securities Act") and the Exchange Act, as the case may
be, and the rules and regulations of the SEC promulgated thereunder applicable
to such Company SEC Documents.  None of the Company SEC Documents contains any
untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading, except to
the extent such statements have been modified or superseded by a later Company
SEC Document.

          (b)  Reservation of Shares; Stock Fully Paid; Validity of Stock and
               --------------------------------------------------------------
Warrants.  The Shares, when issued upon exercise of the Warrants, shall be duly
- --------                                                                       
authorized, validly issued, fully paid, nonassessable, and free from all taxes
(other than income taxes with respect to dividends or distributions thereon and
taxes arising from the disposition thereof), liens, charges, security interests,
restrictions and other encumbrances (except restrictions set forth in this
Agreement or otherwise imposed under applicable securities laws).  The Company
will at all times during each applicable Exercise Period  reserve and keep
available, free from preemptive rights, out of the aggregate of its authorized
but unissued Common Stock, or its authorized and issued Common Stock held in
treasury, for the purpose of enabling it to satisfy any obligation to issue
Shares upon exercise of Warrants, the full number of Shares deliverable upon the
exercise of all outstanding Warrants.  Before taking any action which would
cause an adjustment pursuant to Section 6 reducing any applicable Exercise Price
below the then par value (if any) of the Shares issuable upon exercise of the
Warrants, the Company will take any corporate action that may, in the opinion of
its counsel (which may be counsel employed by the Company), be necessary in
order that the Company may validly and legally issue fully paid and
nonassessable Shares at the Exercise Price as so adjusted.

          (c)  No Impairment. The rights granted to the Registered Holders
               -------------                                              
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to a registered holder of the Company's securities under any
other agreements, except such rights that have been waived.  The Company will
not, by amendment of its Articles of Association or Memorandum of Association,
or through reorganization, consolidation, merger, dissolution, issuance or sale
of securities, sale of assets or any other voluntary action, willfully avoid or
seek to avoid the observance or performance of any of the terms of this
Agreement or the Warrants, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Registered
Holders under this Agreement and the Warrants against wrongful impairment.
Without limiting the generality of the foregoing, the Company:  (i) will take
all such action as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and nonassessable Shares

                                       9
<PAGE>
 
upon the exercise of the Warrants; and (ii) will not on or after the date hereof
enter into any agreement with respect to its securities which is inconsistent
with the rights granted to the Registered Holders under this Agreement or which
otherwise conflicts with the provisions hereof.

          (d)  Taxes.  The Company shall pay any and all issue, documentary
               -----
stamp or other taxes (other than applicable income taxes) that may be payable in
respect of any issuance or delivery of Shares. The Company shall not, however,
be required to pay any tax which may be payable in respect of any transfer
involved in the issuance and delivery of Shares in a name other than that of a
Registered Holder, and no such issuance or delivery shall be made unless and
until the Person to which issuance and delivery is to be made has paid to the
Company the amount of any such tax, or has established, to the satisfaction of
the Company, that such tax has been paid.

                                   SECTION V

     5.1  Representations and Warranties of the Registered Holders.  Each
          --------------------------------------------------------        
Initial Registered Holder, as to itself only, hereby makes the following
representations and warranties for the benefit of the Company:

          (a)  Authorization.  All corporate action on the part of such Initial
               -------------                                                   
Registered Holder that is necessary for the execution, delivery and performance
by such Initial Registered Holder of its obligations under this Agreement has
been taken.  This Agreement has been duly executed and delivered by such Initial
Registered Holder, and this Agreement constitutes the legal, valid and binding
obligation of such Initial Registered Holder, enforceable against it in
accordance with its terms, subject to:  (i) judicial principles respecting
election of remedies or limiting the availability of specific performance,
injunctive relief and other equitable remedies; and (ii) bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
generally relating to or affecting creditors' rights.

          (b)  Restrictions under Securities Laws.  Such Initial Registered
               ----------------------------------                           
Holder is an "accredited investor" within the meaning of Regulation D
promulgated under the Securities Act.  The Warrants and, if exercised, the
Shares are being acquired by such Initial Registered Holder for its own account
for investment and not with a view to the public distribution or resale thereof.
Such Initial Registered Holder understands that the Warrants and Shares have not
been registered under the Securities Act or any state securities or blue sky
laws, by reason of their issuance in a transaction exempt from the registration
requirements thereunder and may not be resold unless the subsequent disposition
thereof is registered thereunder or is exempt from registration thereunder.

                                   SECTION VI

     6.1  Adjustment of Exercise Price and Number of Shares Purchasable.  The
          -------------------------------------------------------------      
Exercise Prices of the Initial Warrants and the Second Warrants and the number
of Shares purchasable

                                       10
<PAGE>
 
upon the exercise of each Warrant are subject to adjustment from time to time as
set forth in this Section 6.1.

          (a)  In case the Company shall at any time after the date of this
Agreement: (i) pay a dividend on the Common Stock in shares of Common Stock,
(ii) subdivide the outstanding shares of Common Stock into a greater number of
shares,  (iii) combine the outstanding shares of Common Stock into a smaller
number of shares, (iv) pay a dividend on the Common Stock in shares of its
capital stock (other than Common Stock), or (v) issue any shares of its capital
stock by reclassification of the shares of Common Stock (other than any
reclassification by way of merger or binding share exchange that is subject to
Section 6.1(h)), the Exercise Price, and the number and kind of Shares
receivable upon exercise, in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification shall be proportionately adjusted so that the holder of any
Warrant exercised after such time shall be entitled to receive the aggregate
number and kind of Shares which, if such Warrant had been exercised immediately
prior to such time, he would have owned upon such exercise and been entitled to
receive by virtue of such dividend, subdivision, combination or
reclassification.  Such adjustment shall be made successively whenever any event
listed above shall occur.  Subject to Section 6.1(f), for a dividend or
distribution, the adjustment shall become effective immediately after the record
date for the dividend or distribution, and for a subdivision, combination or
reclassification, the adjustment shall become effective immediately after the
effective date of the subdivision, combination or reclassification.

          (b)  In case the Company shall issue rights or warrants to all holders
of Common Stock entitling them (for a period expiring within 45 days after the
record date for the determination of stockholders entitled to receive such
rights or warrants) to subscribe for or purchase shares of Common Stock (or
Convertible Securities) at a price per share (or having a conversion price per
share, after adding thereto an allocable portion of the exercise price of the
right or warrant to purchase such Convertible Securities, computed on the basis
of the maximum number of shares of Common Stock issuable upon conversion of such
Convertible Securities) less than the Current Market Price per share on the
Determination Date, the Exercise Price shall be adjusted by multiplying the
Exercise Price in effect immediately prior to such record date by a fraction, of
which the numerator shall be the number of shares of Common Stock outstanding on
such record date plus the number of shares which the aggregate offering price of
the total number of shares of Common Stock so offered (or the aggregate initial
conversion price of the Convertible Securities so offered, after adding thereto
the aggregate exercise price of the rights or warrants to purchase such
Convertible Securities) to holders of Common Stock (and to holders of
Convertible Securities referred to in the following paragraph if the
distribution to which this Section 6.1(b) applies is also being made to such
holders) would purchase at such Current Market Price, and of which the
denominator shall be the number of shares of Common Stock outstanding on such
record date plus the number of additional shares of Common Stock so offered for
subscription or purchase (or into which the Convertible Securities so offered
are initially convertible).  The adjustment contemplated by this Section 6.1(b)
shall be made successively whenever any such rights or warrants are issued and
shall become effective immediately after the close of business on such record
date; however, to the extent that shares of Common Stock (or Convertible
Securities) have not been issued when such rights or warrants expire (or, in the
case of rights or warrants to purchase Convertible Securities which have been

                                       11
<PAGE>
 
exercised, if all of the shares of Common Stock issuable upon conversion of such
Convertible Securities have not been issued prior to the expiration of the
conversion right thereof), the Exercise Price shall be readjusted (but only with
respect to Warrants exercised after such expiration) to the Exercise Price which
would then be in effect had the adjustments made upon the issuance of such
rights or warrants been made upon the basis of delivery of only the number of
shares (or Convertible Securities) actually issued upon the exercise of such
rights or warrants (or the conversion of such Convertible Securities).

          For purposes of this Section 6.1(b) the number of shares of Common
Stock outstanding on any record date shall be deemed to include the maximum
number of shares of Common Stock the issuance of which would be necessary to
effect the full exercise, exchange or conversion of all Convertible Securities
outstanding on such record date which are then exercisable, exchangeable or
convertible at a price (before giving effect to any adjustment to such price for
the distribution to which this Section 6.1(b) is being applied) equal to or less
than the Current Market Price per share of Common Stock on the applicable
Determination Date, if all of such Convertible Securities were deemed to have
been exercised, exchanged or converted immediately prior to the opening of
business on such record date.  In case any subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined by the Board of Directors of the
Company.  Shares of Common Stock owned by or held for the account of the Company
or any majority owned subsidiary shall not be deemed outstanding for the purpose
of any computation under this Section 6.1(b).

          (c)  In case the Company shall distribute to all holders of Common
Stock evidences of its indebtedness or assets or subscription rights or warrants
(excluding (x) dividends or distributions referred to in Section 6.1(a) and
distributions of rights or warrants referred to in Section 6.1(b) and (y) cash
dividends or other cash distributions, unless such cash dividends or cash
distributions are Extraordinary Cash Dividends), the Exercise Price shall be
adjusted by multiplying the Exercise Price in effect immediately prior to the
record date for the determination of stockholders entitled to receive such
distribution by a fraction, of which the numerator shall be the number of shares
of Common Stock outstanding on such record date multiplied by the Current Market
Price on the Determination Date, less the fair market value (as determined by
the Board of Directors of the Company) on such record date of the evidences of
indebtedness, assets, subscription rights or warrants to be distributed to the
holders of Common Stock (and to the holders of Convertible Securities referred
to below if the distribution to which this Section 6.1(c) applies is also being
made to such holders), and of which the denominator shall be the number of
shares of Common Stock outstanding on such record date multiplied by such
Current Market Price.  For purposes of this Section 6.1(c), the number of shares
of Common Stock outstanding on any record date shall be deemed to include the
maximum number of shares of Common Stock the issuance of which would be
necessary to effect the full exercise, exchange or conversion of all Convertible
Securities outstanding on such record date which are then exercisable,
exchangeable or convertible at a price (before giving effect to any adjustment
to such price for the distribution to which this Section 6.1(c) is being
applied) equal to or less than the Current Market Price per share of Common
Stock on the applicable Determination Date, if all of such Convertible
Securities were deemed to have been exercised, exchanged or converted
immediately prior to the opening of business on such record date.

                                       12
<PAGE>
 
          For purposes of this Section 6.1(c), the term "Extraordinary Cash
Dividend" shall mean any cash dividend with respect to the Common Stock the
amount of which, together with the aggregate amount of cash dividends on the
Common Stock to be aggregated with such cash dividend in accordance with the
following provisions of this paragraph, equals or exceeds the threshold
percentage set forth below in the following sentence.  If, upon the date prior
to the Ex-Dividend Date with respect to a cash dividend on Common Stock, the
aggregate of the amount of such cash dividend together with the amounts of all
cash dividends on the Common Stock with Ex-Dividend Dates occurring in the 365
consecutive day period ending on the date prior to the Ex-Dividend Date with
respect to the cash dividend to which this provision is being applied (other
than any such other cash dividends with Ex-Dividend Dates occurring in such
period for which a prior adjustment to the Exercise Price was previously made
under this Section 6.1(c)) equals or exceeds on a per share basis [*] of the
average of the Closing Prices during the period beginning on the date after the
first such Ex-Dividend Date in such period and ending on the date prior to the
Ex-Dividend Date with respect to the cash dividend to which this provision is
being applied (except that if no other cash dividend has had an Ex-Dividend Date
occurring in such period, the period for calculating the average of the Closing
Prices shall be the period commencing 365 days prior to the date immediately
prior to the Ex-Dividend Date with respect to the cash dividend to which this
provision is being applied), such cash dividend together with each other cash
dividend with an Ex-Dividend Date occurring in such 365-day period that is
aggregated with such cash dividend in accordance with this paragraph shall be
deemed to be an Extraordinary Cash Dividend.

     The adjustment pursuant to the foregoing provisions of this Section 6.1(c)
shall be made successively whenever any distribution to which this Section
6.1(c) applies is made, and shall become effective immediately after the record
date for the determination of stockholders entitled to receive the distribution.
Shares of Common Stock owned by or held for the account of the Company or any
majority owned subsidiary shall not be deemed outstanding for the purposes of
any such adjustment.

          (d)  In the event that this Section 6.1 requires adjustments to the
Exercise Price and number of Shares purchasable under more than one of clause
(iv) of the first sentence of Section 6.1(a), Section 6.1(b) or Section 6.1(c),
and the record dates for the distribution giving rise to such adjustments shall
occur on the same date, then such adjustments shall be made by applying, first,
the provisions of Section 6.1(a), second the provisions of Section 6.1(c) and,
third, the provisions of Section 6.1(b).

          (e)  No adjustment in the Exercise Price shall be required if the
amount of such adjustment shall be less than 40 cents per Share; provided,
                                                                 -------- 
however, that any adjustments which by reason of this subsection (e) are not
- -------                                                                     
required to be made shall be carried forward and taken into account in any
subsequent adjustment.  All calculations under this Section 6.1 shall be made to
the nearest cent or to the nearest one-hundredth of a Share, as the case may be.

          (f)  In any case in which this Section 6.1 shall require that an
adjustment in the Exercise Price be made effective as of the record date for a
specified event, the Company may elect to defer until the occurrence of such
event (x) issuing to the holder of any Warrant exercised after such record date
the Shares, if any, issuable upon such exercise over and above

___________
[*] Confidential Treatment Requested.

                                       13
<PAGE>
 
the Shares, if any, issuable upon such exercise on the basis of the Exercise
Price in effect prior to such adjustment and (y) paying to such holder cash or
its check in lieu of any fractional interest to which such holder would be
entitled pursuant to Section 6.2; provided, however, that the Company shall
                                  --------  -------
deliver to such holder a due bill or other appropriate instrument evidencing
such holder's right to receive such additional Shares and such cash upon the
occurrence of the event requiring such adjustment.

          (g)  Upon each adjustment of the Exercise Price as a result of the
calculations made in subsections (a), (b), (c) or (i) of this Section 6.1, each
Warrant outstanding prior to the making of the adjustment in the Exercise Price
shall thereafter evidence the right to purchase, at the adjusted Exercise Price,
that number of Shares (calculated to the nearest hundredth) obtained by (A)
multiplying the number of Shares purchasable upon exercise of a Warrant prior to
adjustment of the number of Shares by the Exercise Price in effect prior to
adjustment of the Exercise Price and (B) dividing the product so obtained by the
Exercise Price in effect after such adjustment of the Exercise Price.

          (h)  If the Company consolidates with or merges into, or transfers
(other than by mortgage or pledge) its properties and assets substantially as an
entirety to, another Person or the Company is a party to a merger or binding
share exchange which reclassifies or changes its outstanding Common Stock, the
Company (or its successor in such transaction) or the transferee  of such
properties and assets shall make appropriate provision so that each Warrant then
outstanding shall thereafter be exercisable, upon the terms and conditions
specified in this Agreement, for the kind and amount of securities, cash or
other assets receivable upon such transaction by a holder of the number of
Shares purchasable upon exercise of such Warrant immediately before the
effective date of such transaction (assuming, to the extent applicable, that
such holder failed to exercise any rights of election with respect thereto, and
received per Share the kind and amount of securities, cash or other assets
received per share of Common Stock by a plurality of the nonelecting shares of
Common Stock); and in any such case, if necessary, the provisions set forth in
this Section 6.1 with respect to the rights and interests thereafter of the
holders of the Warrants shall be appropriately adjusted so as to be applicable,
as nearly as may reasonably be, to any such other securities or assets
thereafter deliverable on the exercise of the Warrants.  The subdivision or
combination of the Common Stock at any time outstanding into a greater or lesser
number of shares of Common Stock shall not be deemed to be a reclassification of
the Common Stock for the purposes of this subsection.  The Company shall not
effect any such consolidation, merger, transfer or binding share exchange unless
prior to or simultaneously with the consummation thereof the successor (if other
than the Company) resulting from such consolidation or merger or the Person
purchasing such assets or other appropriate Person shall assume, by written
instrument, the obligation to deliver to the holder of each Warrant such
securities, cash or other assets as, in accordance with the foregoing
provisions, such holders may be entitled to purchase and the other obligations
under this Agreement.

          (i)  The Company may make such reductions in the Exercise Price, in
addition to those required by subsections (a), (b) and (c) of this Section 6.1,
as it shall in its sole discretion determine to be advisable.

     6.3  Fractional Shares.  If the number of Shares purchasable upon the
          -----------------                                               
exercise of each Warrant is adjusted pursuant to of Section 6.1(g), the Company
shall nonetheless not be required to issue fractions of Shares upon exercise of
the Warrants or to distribute share certificates which evidence fractional
Shares.  In lieu of fractional Shares, there shall be paid to the Registered
Holders at the time such Warrants are exercised as herein provided an amount in
cash equal to the same fraction of the current market value of a Share.  For
purposes of this Section 6.2, the current market value of a Share shall be the
Closing Price of a Share for the Trading Day immediately prior to the date of
such exercise.

Registered Holder written notice of such adjustment setting forth the Exercise
Price after such adjustment and setting forth in reasonable detail the method of
calculation and the facts upon which such calculations are based and setting
forth the number of Shares (or portion thereof) purchasable upon exercise of a
Warrant after such adjustment in the Exercise Price. Where appropriate, such
notice may be given in advance and included as a part of the notice required to
be mailed under the provisions of Section 6.3(b).

          (b)  In case:

               (i)   the Company shall authorize the issuance to all holders of
Common Stock of rights or warrants to subscribe for or purchase shares of Common
Stock or of any other subscription rights or warrants; or

               (ii)  the Company shall authorize the distribution to all holders
of Common Stock of evidences of its indebtedness or assets (other than dividends
payable in Common Stock); or

               (iii) of any consolidation, merger or binding share exchange to
which the Company is a party and for which approval of any shareholders of the
Company is required, or of the conveyance or transfer of the properties and
assets of the Company as, or substantially as, an entirety, or of any
reclassification or change of outstanding Shares issuable upon exercise of the
Warrants (other than a change in par value, or from par value to no par value,
or from no par value to par value, or as a result of a subdivision or
combination); or

               (iv)  of the voluntary or involuntary dissolution, liquidation or
winding up of the Company; or

               (v)   the Company proposes to take any action (other than actions
of the character described in Section 6.1(a), except as required under (iii)
above) which would require an adjustment of the Exercise Price pursuant to
Section 6.1;

then the Company shall cause to be given to each Registered Holder at least 20
days (or 10 days in any case specified in clauses (i) or (ii) above) prior to
the applicable record or effective date

                                       15

hereinafter specified, a written notice stating (x) the date as of which the
holders of record of Common Stock to be entitled to receive any such rights,
warrants or distribution are to be determined, or (y) the date on which any such
consolidation, merger, binding share exchange, conveyance, transfer,
dissolution, liquidation or winding up is expected to become effective, and the
date as of which it is expected that holders of record of Common Stock shall be
entitled to exchange their shares of Common Stock for securities or other
property, if any, deliverable upon such reclassification, consolidation, merger,
binding share exchange, conveyance, transfer, dissolution, liquidation or
winding up. The failure to give the notice required by this Section 6.3(b) or
any defect therein shall not affect the legality or validity of any
distribution, right, warrant, consolidation, merger, binding share exchange,
conveyance, transfer, dissolution, liquidation or winding up, or the vote upon
any such action.

                                  SECTION VII

     7.1  Loss or Mutilation. Upon receipt by the Company of evidence reasonably
          ------------------                                                    
satisfactory to it of the ownership, and the loss, theft, destruction or
mutilation, of a Warrant, and of indemnity reasonably satisfactory to it, and
(in the case of mutilation) upon surrender and cancellation of such Warrant, the
Company will execute and deliver in lieu thereof a new Warrant of like tenor.

     7.2  No Rights or Liabilities as Stockholder. Nothing contained in this
          ---------------------------------------                           
Agreement or in any Warrant shall be construed as conferring upon the holders
thereof the right to vote or to consent or to receive notice as shareholders in
respect of the meetings of shareholders for the election of directors of the
Company or any other matter or any rights whatsoever as shareholders of the
Company.

     7.3  Governmental Approvals; Regulatory Compliance; Standstill Period.
          ---------------------------------------------------------------- 

          (a)  The Company shall from time to time take all action that may be
necessary to obtain and keep effective any and all permits, consents and
approvals of governmental agencies and authorities and filings under federal and
state laws or with any securities exchange or association on which the Common
Stock is listed, which may be or become requisite in connection with the
issuance, sale, transfer and delivery of the Warrants, the exercise of the
Warrants and the issuance, sale, transfer and delivery of the Shares issued upon
exercise of the Warrants; provided, however, the foregoing shall not be
                          --------  -------                            
construed to impose upon the Company any obligation to register the issuance to
or resale by the Registered Holder of the Shares under the Securities Act or any
state securities laws.

          (b)  Without limiting the generality of the foregoing, in the event
that the Company or any Registered Holder reasonably believes that the purchase
of shares of Common Stock to satisfy the Second Vesting Condition or the
exercise of a Warrant and issuance of Shares acquirable upon such exercise
requires prior compliance with the HSR Act and Rules, then any such purchase or
exercise shall be contingent upon such prior compliance and, in the case of the
Warrant exercise shall, subject to effecting such compliance, be effective as of
the Exercise Date.  In the event that compliance with the HSR Act and Rules with
respect to a

                                       16
<PAGE>
 
Warrant exercise is effected after the Expiration Date, such expiration of the
Warrant shall not affect the Registered Holder's right to exercise in accordance
with a notice of exercise delivered to the Company in compliance with Section
3.2 prior to such Expiration Date. To effect such compliance, the Company and
the applicable Registered Holder will, promptly following receipt by the Company
of such Registered Holder's notice of exercise or other written request, use
their respective commercially reasonable efforts to make all filings necessary
to cause the expiration or termination of any applicable waiting period under
the HSR Act and Rules. Each of the Company and each Registered Holder shall bear
and pay the costs or expenses that it incurs in complying with this Section 7.3,
except that each of the Company and the applicable Registered Holder shall pay
one half of any fee payable to the Federal Trade Commission or the Department of
Justice (or any other governmental body then having jurisdiction with respect to
the HSR Act and Rules) in connection with the filing of any reports under the
HSR Act and Rules.

          (c) Notwithstanding the foregoing, during the period commencing on the
date hereof and expiring on the day, corresponding to the date hereof, in the
[*] following the date hereof or, if earlier, the date as of which [*] and [*]
are relieved of their obligations pursuant to this Section 7.3(c) ([*]), [*] and
[*] will not and will not permit any Person of which either of them is the
ultimate parent within the meaning of the HSR Act and Rules to purchase or
otherwise acquire any shares of Common Stock or other voting securities of the
Company the acquisition of which would result in the acquiring person (within
the meaning of the HSR Act and Rules) owning [*] of the Common Stock or other
voting securities of the Company (as determined pursuant to [*]. The [*] will
expire on such earlier date, if any, on which (i) the Company has advised [*]
and [*] that it is releasing them from their obligations hereunder, or (ii)
another Person makes an offer to the Board of Directors of the Company or to the
Company's stockholders to acquire [*] of the Common Stock of the Company
(whether by tender or exchange offer, merger, consolidation, binding share
exchange or otherwise), and the Company [*].

     7.4  Mechanics and Effects of Transfer.  An assignment, conveyance or other
          ---------------------------------

the Company maintained for such purpose at the principal office of the Company
upon surrender of any such Warrant together with a properly completed assignment
in the form of Exhibit 2 to the forms of Warrant attached hereto duly executed
by the Registered Holder. Upon any such registration of transfer, a new Warrant
shall be issued to the transferee and the surrendered Warrant shall be canceled.
Notwithstanding the foregoing, the Warrant and the rights under this Agreement
may not be assigned, conveyed or transferred unless (i) such assignment,
conveyance or transfer complies with all applicable securities laws and the
provisions of this Agreement, including Section 7.5, and (ii) the transferee
agrees in writing to be bound by the terms of this Agreement, including the
restrictions set forth in Section 7.5.

          ------

assigned or otherwise transferred to any Person (i) in the case of the Warrants,

any other Qualifying Shares, the date such Qualifying Share is purchased, and
ending on the corresponding day in the [*] following the Initial Vesting Date or
the applicable purchase date, as applicable (or, if there is no such
corresponding day in such [*], then the last day of such [*]) and (iii) as to
any Shares, during the period commencing on the date such Share is first issued
("Issue Date") and ending on the corresponding day in the [*] following the
Issue Date (or, if there is no such corresponding day in such [*], then the last
day of such [*]), except that a Registered Holder may transfer its Warrant, any
Shares purchased thereunder and any Qualifying Shares (x) to an Affiliate of
such Registered Holder that agrees in writing to be bound by the terms of this
Agreement and (y) to a Person that is not an Affiliate of such Registered Holder
pursuant to a public offer made by such Person to acquire 50% or more of the
outstanding shares of Common Stock. Further, if any designated Holder desires to
pledge any of the Warrants, any Qualifying Shares or any Shares, then it shall
be a condition to the effectiveness of any such pledge during the applicable of
the foregoing periods that the pledgee agree in writing to be bound by the
provisions of this Section 7.5 as if it were the pledgor hereunder.

     7.6  Legends; Notations.
          ------------------ 

          (a)  The certificates evidencing the Warrants and the Shares shall be

any legend required by any applicable state securities law.

          (b)  The Company shall make a notation on its stock books regarding
the restrictions on transfer of the Warrants and Shares required by applicable
securities and other laws and imposed pursuant to this Agreement and will
transfer securities on the books of the Company only to the extent not
inconsistent therewith. Without limiting the generality of the foregoing, the
Company shall refuse to register any transfer of the Warrants or Shares not made
in accordance with the registration requirements of the Securities Act or
pursuant to an applicable exemption from registration under the Securities Act.
