                                   WITNESSETH:

Company, Newco and the Executive; and

      WHEREAS, the Company and Newco wish to assure themselves of the services
of the Executive for the period hereinafter provided, and the Executive is
willing to be employed by Newco for said period, upon the terms and conditions
provided in this Agreement;

      NOW, THEREFORE, in consideration of the premises and mutual covenants
contained herein and for other good and valuable consideration, the receipt of

      3. Position and Duties; Place of Performance.

            (a) The Executive will serve as President and Chief Operating
      Officer of Newco and will perform all duties customarily attendant to the
      position of President and Chief Operating Officer and such other duties as
      may reasonably be assigned from time-to-time by the Board of Directors of
      the Company (the "Board") that are consistent with his position as
      President and Chief Operating Officer.

            (b) The Executive will devote his full business time and best
      efforts to his employment and perform diligently such duties as are
      consistent with his capacity as President and Chief Operating Officer of
      Newco and such other duties as the Board reasonably determines that are
      consistent with his position. The Executive will devote his entire working
      time and attention to the performance of his responsibilities hereunder;
      provided, the Executive may make personal investments, engage in outside
      non-competitive business activities or engage in other activities for any
      charitable or other non-profit institution, provided that such activities
      do not interfere with the performance of the Executive's duties hereunder.

            (c) In connection with the Executive's employment by Newco, the
      Executive will be based at Newco's place of business which on the date

      4. Base Salary. The Executive will receive from Newco or the Company an
annual base salary of One Hundred Seventy-Five Thousand Dollars ($175,000) (as
from time to time adjusted, the "Base Salary"), payable in accordance with the

salaries of its employees. The Board will review the Base Salary annually, and
may, in its reasonable discretion, adjust the Base Salary.

      5. Annual Bonus. (a) General. The Executive may be paid a bonus annually
based upon the attainment of objectives determined by the Board after
consultation with the Executive. Within 90 days after the start of each fiscal
year, the Board will communicate to the Executive the objectives applicable to
such fiscal year and, unless the Board and the Executive shall mutually agree
otherwise, such objectives shall apply to such fiscal year. For the year ended
December 31, 2005, if the Executive is employed by Newco on December 31, 2005,
the Executive shall be entitled to receive a bonus payment equal to 12.5% of the
amount, if any, by which Newco EBITDA for the 2005 fiscal year (on a pro forma
combined basis, assuming that Newco had been formed on December 31, 2004)
exceeds $1,200,000, up to a maximum bonus payment of $175,000; provided,
however, the Executive may elect not to receive a bonus payment with respect to
any fiscal year by providing written notice of such election to the Company at
any time prior to such payment. For purposes of this Agreement, "Newco EBITDA"
shall mean, with respect to a fiscal year of Newco, the sum of (without
duplication) (a) Newco Net Income for such fiscal year and (b) to the extent
Newco Net Income has been reduced thereby, (i) all income taxes of Newco
recorded as a tax provision in accordance with GAAP for

such period, (ii) Newco Interest Expense, (iii) Newco Non-Cash Charges and (iv)
all management fees required to be paid by Newco to the Company, all as
determined in accordance with GAAP. The components of Newco EBITDA will be
determined by the Company's independent auditor in accordance with GAAP, subject
to Section 5(c) below.

      (b) Definitions. "Newco Interest Expense" shall mean, with respect to a
fiscal year of Newco, the sum of (without duplication) (a) the aggregate of the
interest expense of Newco for such fiscal year determined in accordance with
GAAP and (b) the interest component of capitalized lease obligations accrued by
Newco during such period as determined in accordance with GAAP, less (c) the
amount of any interest income received by Newco during such fiscal period.

      "Newco Net Income" shall mean, with respect to a fiscal year of Newco, the
aggregate net income (or loss) of Newco for such fiscal year, determined in
accordance with GAAP.

      "Newco Non-Cash Charges" shall mean, with respect to a fiscal year of
Newco, the aggregate depreciation and amortization of Newco reducing Newco Net
Income for such fiscal year (including any depreciation or amortization of the
Company or any of its Subsidiaries other than Newco that was allocated to Newco,
if applicable).

      "GAAP" shall mean United States generally accepted accounting principles
as set forth in the opinions and pronouncements of the Accounting Principles
Board of the American Institute of Certified Public Accountants and statements
and pronouncements of the Financial Accounting Standards Board or in other such
statements by such other entity as have been approved by a significant segment
of the accounting profession, as in effect for the relevant time period.

      (c) Disputes. The determination of Newco EBITDA for the year ended
December 31, 2005, and any disputes in respect thereof, shall be handled in the
manner specified in Sections 2.07(a) and (b) of the Amended and Restated
Agreement and Plan of Merger dated as of July 16, 2004 among the Company,
DCPS/MBS Acquisition, Inc., Dennis Cain Physician Solutions, Ltd., Medical
Billing Services, Inc. and the sellers party thereto, as amended (the "Merger

      with such medical, hospitalization, insurance, pension plan, equity
      incentive, profit sharing and employee benefits, cell phone and such other
      similar employment privileges and benefits ("Benefits") as are afforded
      generally from time to time to executive employees of the Company, and

            turpitude, or his commission of fraud, embezzlement, theft,
            dishonesty, willful misconduct or deliberate injury to the Company
            or its subsidiaries;

                  (ii) the Executive's intentional or grossly negligent refusal
            or failure to perform his duties or carry out written directions of
            the Company's chief executive officer or Board, which refusal or
            failure remains uncured or continues more than thirty (30) days
            after written notice from the Company specifying in reasonable
            detail the nature of the breach, or recurs within such period;

                  (iii) the Executive's breach of any of his fiduciary duties to
            Newco or the Company or making of a willful misrepresentation or
            omission, which breach or misrepresentation or omission might
            reasonably be expected to have a material adverse effect on Newco's
            or the Company's business and which remains uncured or continues
            more than thirty (30) days after written notice from the Company
            specifying in reasonable detail the nature of the breach or
            misrepresentation or omission, or recurs within such period;

                  (iv) the Executive's breach of any material provision of this

            more than thirty (30) days after written notice from the Company
            specifying in reasonable detail the nature of the breach, or recurs
            within such period; or

                                       4
<PAGE>

                  (v) any misappropriation by the Executive of funds or property
            of the Company or any affiliate of the Company.

      Any termination for "Cause" will not be in limitation of any other right
      or remedy the Company or Newco may have under this Agreement or otherwise.

            (d) Good Reason. The Executive may terminate his employment under
      this Agreement for Good Reason. For purposes of this Agreement, the
      Executive will have "Good Reason" to terminate the Executive's employment
      upon the occurrence of any of the following circumstances, without the
      Executive's express written consent: (i) a material diminution in the
      Executive's position or authority (except during periods when the
      Executive is unable to perform all or substantially all of the Executive's
      duties and/or responsibilities as a result of the Executive's illness
      (either physical or mental) or other incapacity); (ii) a requirement by
      the Company that the Executive change the Executive's principal place of
      business to a place more than thirty (30) miles from its location on the
      date of this Agreement; (iii) a termination of employment by the Executive
      within ninety (90) days following a Change in Control (as defined below),
      provided, that Good Reason will not exist if the Executive has accepted or
      agreed to continue employment following the Change of Control with the
      surviving or successor entity and such surviving or successor entity has
      agreed to continue or assume this Agreement, provided, further, in the
      event of a Change of Control, the Executive is under no obligation to
      continue or accept employment with the surviving or successor entity and
      may instead elect to terminate his employment for Good Reason upon such
      Change of Control; (iv) a breach of this Agreement by Newco or the Company
      which is not cured within thirty (30) days of written notice by the
      Executive; (v) any reduction in the Executive's Base Salary or any change
      adverse to the Executive in the bonus objectives applicable to a fiscal
      year after the communication of such objectives to the Executive pursuant
      to Section 5(a); or (vi) a failure by the Company (a "Payment Default") to
      pay any amounts due to an MBS Seller (as defined in the Merger Agreement)
      pursuant to (A) Section 2.07(c) of the Merger Agreement or (B) the MBS
      Notes (as defined in the Merger Agreement), in either case within 180 days
      of such payment becoming due. The Executive's right to terminate
      employment pursuant to this subsection 8(d) will not be affected by the
      Executive's Disability. The Executive's continued employment will not
      constitute consent to, or a waiver of rights with respect to, any
      circumstance constituting consent to, or a waiver of rights with respect
      to, any circumstance constituting Good Reason; provided, however, that the
      Executive will be deemed to have waived his rights pursuant to
      circumstances constituting Good Reason if he has not provided to the
      Company a Notice of Termination (as defined below) within ninety (90) days
      following his knowledge of the circumstances constituting Good Reason. A
      waiver with respect to the circumstances constituting Good Reason will not
      act as a waiver with respect to other future circumstances constituting
      Good Reason.

            Any termination of the Executive's employment by the Executive must
      be communicated by written Notice of Termination to the Company in
      accordance with Section 19. For purposes of this Agreement, a "Notice of
      Termination" means a notice

                                       5
<PAGE>

      which indicates the specific termination provision in this Agreement
      relied upon and sets forth in reasonable detail the facts and
      circumstances claimed to provide a basis for termination of the
      Executive's employment under the provision so indicated.

            For purposes of this Agreement, a "Change in Control" will occur:
      (i) upon the sale or other disposition of 50% or more of the consolidated
      assets of the Company taken as a whole; (ii) if shares representing a
      majority of the voting power of the Company are acquired by a person or
      group (as such term is used in Rule 13d-5 promulgated under the Securities
      Exchange Act of 1934, as amended) of persons other than the holders of the
      capital stock of the Company as of the date of this Agreement; (iii) upon
      a merger or consolidation pursuant to which the holders of the equity
      securities of the Company before the merger or consolidation do not own
      equity securities representing a majority of the voting power of the
      surviving entity after the merger or consolidation; or (iv) upon approval
      by the shareholders of the Company of a complete liquidation or
      dissolution of the Company.

      9. Compensation Upon Termination.

            (a) If the Executive's employment is terminated as a result of the
      Executive's death or Disability, he, or his estate, will be entitled to:

                  (ii) any bonus awarded pursuant to Section 5 of this Agreement
            but not yet paid, payable as soon as administratively feasible
            following termination of employment;

                  (iii) a prorated bonus for the year in which his employment
            terminates, prorated based on the number of days worked, minus any
            bonus payments made pursuant to Section 5 of this Agreement in
            respect of the year containing the date of termination, payable as
            soon as administratively feasible following the end of the then
            current fiscal year of the Company;

                  (iv) reimbursement in accordance with this Agreement of any
            business expense incurred by the Executive but not yet paid, payable
            as soon as administratively feasible following termination of
            employment; and

                  (v) other benefits accrued and earned by the Executive through
            the date of his death or Disability in accordance with applicable
            plans and programs of the Company.

            (b) If the Executive's employment is terminated by the Company for
      Cause, or by the Executive other than for Good Reason, or as a result of
      notice of nonrenewal provided by the Company or the Executive under
      Section 2, he will be entitled to:

                  (i) any Base Salary earned but not yet paid;

                  (ii) reimbursement in accordance with this Agreement of any
            business expense incurred by the Executive but not yet paid, payable
            as soon as administratively feasible following termination of
            employment;

                  (iii) other benefits accrued and earned by the Executive
            through the date of his termination in accordance with applicable
            plans and programs of the Company;

                  (iv) if the Executive's employment is terminated as a result
            of notice of nonrenewal provided by the Executive under Section 2,
            he will be entitled to a prorated bonus for the year in which his
            employment terminates, prorated based on the number of days worked,
            minus any bonus payments made pursuant to Section 5 of this
            Agreement in respect of the year containing the date of termination,
            payable as soon as administratively feasible following the end of
            the then current fiscal year of the Company; and

                  (v) if the Executive's employment is terminated as a result of
            notice of nonrenewal provided by the Company under Section 2, he
            will be entitled to full vesting of any unvested equity incentives,
            including without limitation stock options, restricted stock and
            deferred restricted stock units.

            (c) If the Executive's employment is terminated by the Company
      without Cause, or by the Executive for Good Reason, he will be entitled
      to:

                  (i) any Base Salary earned but not yet paid;

                  (ii) any bonus awarded pursuant to Section 5 of this Agreement
            but not yet paid, payable as soon as administratively feasible

                  (iii) continuation of his Base Salary, at the rate in effect
            on the date of his termination of employment (which, in the case of
            a termination of the Executive for Good Reason pursuant to Section
            8(d)(v), shall be deemed to be the rate in effect prior to giving
            any effect to the reduction in Base Salary giving rise to such Good
            Reason), until the expiration of the Non-Competition Period (as
            defined below);

                  (iv) the greater of: (A) a prorated bonus for the year in
            which employment terminates, prorated based on the number of days

            Agreement in respect of the year containing the date of termination,
            payable in

                                       7
<PAGE>

            either event as soon as administratively feasible following the end
            of the then fiscal year of the Company; provided, however, that this
            clause (iv) shall not be applicable in the event that the
            Executive's employment is terminated upon notice of nonrenewal
            provided by the Company under Section 2;

                  (v) until the expiration of the Non-Competition Period,
            subject to any employee contribution applicable to the Executive on
            the date of termination, continued participation in all of the
            Company's group medical and dental insurance plans in which he was
            participating on the date of his termination of employment, provided
            that the Executive is entitled to continue such participation under
            applicable law and plan terms;

                  (vi) reimbursement in accordance with this Agreement of any
            business expenses incurred by the Executive but not yet paid to him
            on the date of his termination of employment, payable as soon as
            administratively feasible following termination of employment; and

                  (vii) full vesting of any unvested equity incentives,
            including without limitation stock options, restricted stock and
            deferred restricted stock units.

            In the event that, under the terms of any employee benefit plan
      referred to in subsection 9(c)(v) above, the Executive may not continue
      his participation, he will be provided with the after-tax economic
      equivalent of the benefits provided under any plan in which he was
      previously eligible to participate for the period specified in subsection
      9(c)(v) above. The economic equivalent of any benefit foregone will be
      deemed to be the cost that would be incurred by the Executive in obtaining
      such benefit on the lowest available individual basis.

            (d) Any amounts due under this Section 9 are in the nature of
      severance payments or liquidated damages or both, and, to the extent
      received by the Executive, will fully compensate the Executive and his
      dependents or beneficiaries, as the case may be, for any and all direct
      damages and consequential damages that any of them may suffer as a result
      of termination of the Executive's employment, and they are not in the
      nature of a penalty.

            (e) Notwithstanding anything contained herein, any obligation of the
      Company or Newco to the Executive under Sections 9(c)(iii), (iv), (v) and
      (vii) is conditioned upon (i) the Executive signing a release of claims in
      the form attached hereto as Exhibit A (the "Employee Release") within
      twenty-one days (or such greater period as the Company may specify)
      following the later of the date on which the Executive (or, in the case of
      termination by the Executive for Good Reason, the Company) receives notice
      of termination of employment or the date the Executive receives a copy of
      the Employee Release and upon the Executive not revoking the Employee
      Release in a timely manner thereafter and (ii) the Executive's continuing
      compliance with the provisions of Section 10. If the Executive breaches
      any provision of Section 10, upon written notice of such

                                       8
<PAGE>

      breach and request for repayment from the Company, the Executive shall
      promptly pay to the Company an amount equal to the sum of any cash
      payments previously paid to the Executive pursuant to Sections 9(c)(iii),
      (iv), (v) and (vii). Any such repayment shall not be the exclusive remedy
      for any such breach and the Company and Newco shall retain all rights to
      pursue other available remedies (whether at law or equity) for any such
      breach.

      10. Confidentiality and Non-Competition.

            (a) The Executive acknowledges that he has had or will have
      unlimited access to confidential information and business methods relating
      to the Company's and Newco's business and operations and that the Company
      and Newco would be irreparably injured and the goodwill of the Company and
      Newco would be irreparably damaged if the Executive were to breach the
      covenants set forth in this Section 10. The Executive further acknowledges
      that the covenants set forth in this Section 10 are reasonable in scope
      and duration and do not unreasonably restrict the Executive's association
      with other business entities, either as an employee or otherwise as set
      forth herein.

            (b) During the Term of Employment and thereafter, except as may be
      required by law or necessary in connection with any dealings with any
      public agency or authority or in the ordinary course of business during
      the Term of Employment pursuant to customary non-disclosure agreements,
      the Executive will not disclose, disseminate, divulge, discuss, copy or
      otherwise use or suffer to be used, including but not limited to in
      competition with, or in a manner harmful to the interests of, the Company
      or Newco, any confidential information (written or oral) respecting any
      material aspect of the Company's or Newco's business, excepting only use
      of such data or information as is (i) at the time disclosed, through no
      act or failure to act on the part of the Executive, generally known or
      available; (ii) furnished to the Executive by a third party as a matter of
      right and without restriction on disclosure; or (iii) required to be
      disclosed by court order. Upon termination of the Term of Employment, the
      Executive will return to the Company any and all materials in tangible or
      electronic form containing confidential information belonging to the
      Company or Newco.

            (c) During the Term of Employment and continuing until the earlier
      of the termination of the Non-Competition Period or the date on which the
      Executive terminates his employment with Newco for Good Reason upon a
      Payment Default, the Executive will not in the states of California,
      Florida, Georgia, Illinois, Iowa, New Jersey, Ohio or Texas, directly or
      indirectly, whether as an individual on the Executive's own account, or as
      a shareholder, partner, member, joint venturer, director, officer,
      employee, consultant, creditor and/or agent, of any person, firm or
      organization or otherwise:

                  (i) own, manage, control or participate in the ownership,
            management or control of, or be employed or engaged by or otherwise
            affiliated or associated as a consultant, independent contractor or
            otherwise with, any other corporation, partnership, proprietorship,
            firm, association or other business entity or otherwise engage in
            any business that is engaged in the business of the Company or any
            of

                                       9
<PAGE>

            the Company's subsidiaries (collectively, "Subsidiaries"), as such
            business is conducted on the applicable date during the Term of
            Employment, or in the case of the Non-Competition Period, as of the
            date the Executive ceases to be employed by Newco, in any capacity,
            including as a consultant;

                  (ii) directly or indirectly solicit, encourage or induce any
            person who is a present or future employee, officer, agent,
            affiliate or customer of the Company or any Subsidiary to terminate
            or materially alter such person's relationship with the Company or
            such Subsidiary;

                  (iii) induce any supplier of the Company or any Subsidiary, to
            refuse to do business with the Company or any Subsidiary, on as
            favorable terms as previously done with the Company or any
            Subsidiary, as the case may be; or

                  (iv) engage in disparagement (which will not include the
            providing of accurate information without invidious intent) of the
            Company or any Subsidiary by any means to any person.

      For purposes of this Agreement, "Non-Competition Period" shall mean the
      period during the Term of Employment and thereafter until the second
      anniversary of the date of termination of the Executive's employment with
      Newco; provided, however, that the Company may, by written notice to the
      Executive (whether given before or after the date of termination of the
      Executive's employment with Newco), shorten the portion of the
      Non-Competition Period occurring following the date of termination of the
      Executive's employment with Newco to any date specified in such notice
      which occurs on or after the earlier of (x) the second anniversary of the
      date of termination of the Executive's employment with Newco and (y) the
      date of expiration of the then current Term of Employment. Notwithstanding
      anything herein to the contrary, the Non-Competition Period shall
      terminate if the Company and Newco fail to pay any amounts due to the
      Executive under this Agreement within sixty (60) days of such payment
      being due. Notwithstanding the foregoing, in the event that the Company or
      the Executive provides notice of nonrenewal under Section 2, then: (1) the
      Company shall have the option to continue to pay the Executive his Base
      Salary, at the rate in effect on the date of his termination of
      employment, until the expiration of the Non-Competition Period; (2) if the
      Company exercises such option, it may discontinue the payment of Base
      Salary at any time; (3) the Executive shall be subject to Section 10(c)(i)
      only for so long as the Company continues to pay the Executive his Base
      Salary; and (4) if the Company stops paying the Executive his Base Salary,
      then the Executive shall no longer be subject to Section 10(c)(i), but
      shall remain subject to the rest of this Section 10.

            (d) Notwithstanding anything herein to the contrary, the Executive
      will be permitted to own shares of any class of capital stock of any
      publicly held corporation so long as the aggregate holdings of the
      Executive represent less than one percent (1%) of the outstanding shares
      of such class of capital stock.

      11. Rights and Remedies Upon Breach.

            (a) The Executive expressly agrees and understands that the remedy
      at law for any breach by the Executive of Section 10 will be inadequate
      and that the damages flowing from such breach are not readily susceptible
      to being measured in monetary terms. Accordingly, it is acknowledged that
      upon adequate proof of the Executive's violation of Section 10, the
      Company and Newco will be entitled, among other remedies, to injunctive
      relief and may obtain a temporary restraining order restraining any
      threatened or further breach. Nothing in this Section 11(a) will be deemed
      to limit the Company's or Newco's remedies at law or in equity for any
      breach by the Executive of any of the provisions of this Agreement which
      may be pursued or availed of by the Company or Newco.

            (b) In the event any court of competent jurisdiction determines that
      the specified time period or geographical area set forth in Section 10 is
      unreasonable, arbitrary or against public policy, then a lesser time
      period or geographical area that is determined by the court to be
      reasonable, non-arbitrary and not against public policy may be enforced.

      12. Withholding Taxes. All payments to the Executive or his beneficiary
will be subject to withholding on account of federal, state and local taxes as
required by law. If any payment hereunder is insufficient to provide the amount
of such taxes required to be withheld, the Company or Newco may withhold such
taxes from any other payment due the Executive or his beneficiary.

      13. Assignability; Binding Nature. This Agreement will be binding upon and
inure to the benefit of the Parties and their respective successors, heirs (in
the case of the Executive) and assigns. No rights or obligations of the Company
or Newco under this Agreement may be assigned or transferred by the Company or
Newco except that such rights or obligations may be assigned or transferred
pursuant to (i) a merger or consolidation in which the Company or Newco is not
the continuing entity or (ii) a sale or liquidation of all or substantially all
of the assets of the Company or Newco, provided that the assignee or transferee
is the successor to all or substantially all of the assets of the Company or
Newco, as applicable, and such assignee or transferee assumes the liabilities,
obligations and duties of the Company or Newco, as applicable, as contained in
this Agreement, either contractually or as a matter of law. Each of the Company
and Newco further agrees that, in the event of a sale of assets or liquidation
as described in the preceding sentence, it will use its best efforts to cause
such assignee or transferee to expressly assume the liabilities, obligations and
duties of the Company or Newco, as applicable, hereunder. No obligations of the
Executive under this Agreement may be assigned or transferred by the Executive.
Notwithstanding anything to the contrary contained in this Agreement, if the
Sellers exercise the ROFR (as defined in Section 6.11 of the Merger Agreement)
and purchase the capital stock or assets of Newco pursuant thereto, this
Agreement shall immediately terminate without further obligation on the part of
any party hereto; provided, however, that the Executive shall continue to be
bound by the provisions of Sections 10(a) and 10(b) with respect to confidential
information of the Company.

Agreement contains the entire understanding and agreement between the Parties
concerning the subject matter hereof and supersedes any prior agreements,
whether written or oral, between the Parties concerning the subject matter
hereof.

      15. Amendment or Waiver. No provision in this Agreement may be amended
unless such amendment is agreed to in writing and signed by both the Executive
and an authorized officer of the Company. No waiver by either Party of any
breach by the other Party of any condition or provision contained in this
Agreement to be performed by such other Party will be deemed a waiver of a
similar or dissimilar condition or provision at the same or any prior or
subsequent time. Any waiver must be in writing and signed by the Executive or an
authorized officer of the Company, as the case may be.

      16. Severability. In the event that any provision or portion of this
Agreement is determined to be invalid or unenforceable for any reason, in whole
or in part, the remaining provisions of this Agreement will be unaffected
thereby and will remain in full force and effect to the fullest extent permitted
by law.

      17. Survivorship. The respective rights and obligations of the Parties
hereunder will survive any termination of the Executive's employment with Newco
to the extent necessary to the intended preservation of such rights and
obligations as described in this Agreement.

      18. Governing Law. This Agreement will be governed by and construed and
interpreted in accordance with the laws of the State of Texas, without reference
to principles of conflict of laws.

         2.4. Time Limitation. The Company will not be required to effect any
registration pursuant to Section 2.1 within six months after the effective date
of any Registration Statement that was requested pursuant to Section 2.1.

         2.5. Selection of Underwriter. If a Majority in Interest of the
Registrable Shares intend to distribute the Registrable Shares in an
underwritten offering, they will so advise the Company in their request. A
Majority in Interest of the Registrable Shares making such request will have the
right to designate the managing underwriter, subject to the approval of the
Company, which approval may not be unreasonably withheld.

3. INCIDENTAL REGISTRATION.

         3.1. Company Registration. If at any time the Company proposes to
register any of its equity securities under the Securities Act, for its own
account (other than a Registration Statement on Form S-4 or S-8 or any successor
thereto) or for the account of any holder of its securities other than
Registrable Shares, then at least 20 days prior to the anticipated filing date
of the applicable Registration Statement the Company will give written notice to
all Holders (which notice will describe the proposed registration and state the
intended method of disposition and provide such Holders the opportunity to
register the number of Registrable Shares as each such Holder may request,
subject in each case to the terms of this Agreement) of such proposed filing,
and upon the written request of a Holder or Holders given within 20 days after
the Company provides such notice, the Company will use its Best Efforts to cause
all Registrable Shares that the Company has been requested to register to be
registered under the Securities Act to the extent necessary to permit their sale
or other disposition in accordance with the intended methods of distribution
specified in the request of such Holder(s); provided that, the Company will have
the right to postpone or withdraw any registration initiated by the Company
pursuant to this Section 3.1 without obligation to any Holder; provided,
further, that in the case of a proposed underwritten offering, the Company shall
use its Best Efforts to cause the managing underwriter or underwriters to permit
each of the Holders who have requested in writing to participate in the offering
to include such Holder's Registrable Shares in such offering on the same terms
and conditions as are applicable to the securities of the Company or other
stockholders, as the case may be, included therein.

         3.2. Excluded Transactions. The Company will not be obligated to effect
any registration of Registrable Shares under this Section 3 incidental to the
registration of any of its securities in connection with: (a) a registration on
Form S-8 relating to employee benefit plans or dividend reinvestment plans; or
(b) a registration on Form S-4 relating to the acquisition or merger after the
date hereof by the Company or any of its subsidiaries of or with any other
businesses.

4. REGISTRATION PROCEDURES. If and whenever the Company is required by the
provisions of this Agreement to use its Best Efforts to effect the registration
of any of the Registrable Shares under the Securities Act, the Company and the
Selling Holders will take the actions described below in this Section 4.

                                      -5-
<PAGE>

         4.1. Registration Statement. The Company will prepare and (in the case
of a registration pursuant to Section 2 hereof, promptly and in any event within
60 days after the end of the period within which requests for registration may
be delivered to the Company) file with the Commission a Registration Statement
with respect to such Registrable Shares and use its Best Efforts to cause such
Registration Statement to become effective within 60 days after the filing of
such Registration Statement. Such Registration Statement shall be for an
offering to be made on a continuous or delayed basis (a so-called "shelf
registration statement") if (i) the Company is eligible for the use thereof and
(ii) the Holders requesting such registration have asked for a shelf
registration statement, and the Company shall keep such Registration Statement
effective pursuant to Rule 415 for the Effectiveness Period.

         4.2. Amendments and Supplements. The Company will prepare and file with
the Commission such amendments (including post-effective amendments) and
supplements to such Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective
during the Effectiveness Period, and during such period to comply with the
provisions of the Securities Act with respect to the disposition of all
Registrable Shares and other securities, if any, covered by such Registration
Statement until the end of the Effectiveness Period.

         4.3. Cooperation. The Company will use its Best Efforts to cooperate
with the Selling Holders in the disposition of the Registrable Shares covered by
such Registration Statement, including without limitation in the case of an
underwritten offering pursuant to Section 2.1 entering into and performing
customary agreements (including an underwriting agreement in customary form with
the managing underwriter) and causing key executives of the Company and its
subsidiaries to participate under the direction of the managing underwriter in a
"road show" scheduled by such managing underwriter in such locations and of such
duration as in the judgment of such managing underwriter are appropriate for
such underwritten offering.

         4.4. Copies of Prospectus. The Company will furnish to each Selling
Holder, without charge, (i) promptly after such Registration Statement is filed
with the Commission, such reasonable numbers of copies of the prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and any amendments thereto, including financial statements and
schedules and all exhibits, (ii) upon the effectiveness of such Registration
Statement, such number of copies of the prospectus included in such Registration
Statement, including all amendments and supplements thereto, and (iii) such
other documents, in each case, as the Selling Holder may reasonably request in
order to facilitate the public sale or other disposition of the Registrable
Shares owned by the Selling Holder.

         4.5. Blue Sky Qualification. The Company will use its Best Efforts to
register or qualify the Registrable Shares covered by the Registration Statement
under the securities or "blue sky" laws of such states or jurisdictions in the
United States as the Selling Holders reasonably request, and do any and all
other acts and things that may be necessary or desirable to enable the Selling
Holders to consummate the public sale or other disposition in such jurisdictions
of the Registrable Shares covered by the Registration Statement, including
preparing and filing in those jurisdictions such amendments (including
post-effective amendments) and supplements to such registrations and
qualifications as may be necessary to maintain the effectiveness thereof during
the Effectiveness Period (in the case of a shelf

                                      -6-
<PAGE>

registration statement); provided, however, that the Company will not be
obligated to file any general consent to service of process or to qualify as a
foreign corporation in any jurisdiction in which it is not so qualified or to
subject itself to taxation in respect of doing business in any jurisdiction in
which it would not otherwise be so subject. The Company shall promptly notify
each Selling Holder of the receipt by the Company of any notification with
respect to the suspension of the registration or qualification of any
Registrable Shares for sale under the securities or "blue sky" laws of any
jurisdiction in the United States or its receipt of actual notice of the
initiation or threat of any proceeding for such purpose.

         4.6. Opinion of Counsel; Comfort Letter. In the case of an underwritten
offering, the Company will use its Best Efforts to obtain all legal opinions,
auditors' consents and comfort letters and experts' cooperation as may be
required, including furnishing to each Selling Holder of such Registrable Shares
a signed counterpart, addressed or confirmed to such Selling Holder, of (a) an
opinion of counsel for the Company and (b) a "cold comfort" letter signed by the
independent public accountants who have certified the Company's financial
statements included in such Registration Statement, covering substantially the
same matters as are customarily covered in opinions of issuer's counsel and in
accountants' letters delivered to underwriters in underwritten public offerings
of securities.

         4.7. Listing and Transfer Agent. The Company will cause all Registrable
Shares covered by the Registration Statement to be listed on each securities
exchange or automated quotation system on which the Class A Common Stock is then
listed. The Company will provide and cause to be maintained a transfer agent and
registrar for all Registrable Shares covered by the Registration Statement not
later than the effective date of such Registration Statement. The Company will
pay all fees and expenses in connection with satisfying its obligations under
this Section 4.7.

         4.8. General Compliance with Federal Securities Laws; Section 11(a)
Earning Statement. The Company will use its Best Efforts to comply with the
Securities Act, the Exchange Act and any other applicable rules and regulations
of the Commission, and make available to its securities holders, as soon as
reasonably practicable, an earning statement covering the period of at least 12
months after the effective date of such Registration Statement, which earnings
statement shall be in a form complying with and satisfying Section 11(a) of the
Securities Act and any applicable regulations thereunder, including the
provisions of Rule 158.

         4.9. Notice of Prospectus Defects. The Company will immediately notify
the Selling Holders of the happening of any event, as a result of which the
prospectus included or to be included in the Registration Statement, as then in
effect, includes an untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing (provided
that such notice shall not contain any material, non-public information). The
Company will promptly revise such prospectus as may be necessary so that such
prospectus shall not include an untrue statement of a material fact or omit to
state such a material fact required to be stated therein or necessary to make
the statements therein not misleading in the light of the circumstances then
existing. The Company will promptly deliver copies of such revised prospectus to
the Selling Holders. Following receipt of the revised prospectus, the Selling
Holders will be free to resume making offers of the Registrable Shares. The
Company will

                                      -7-
<PAGE>

extend the period during which the Registration Statement must be kept effective
pursuant to this Agreement by the number of days during the period from and
including the date of giving such notice to and including the date when the
Selling Holders shall have received copies of the revised prospectus.

         4.10. Company Lock-Up. In the case of an underwritten offering
requested to be effected by the Holders hereunder, the Company will refrain,
without the consent of the managing underwriter, for a period from 15 days
before the effective date of the registration sale until 90 days after such
effective date, from directly or indirectly selling, offering to sell, granting
any option for the sale of, or otherwise disposing of any common equity or
securities convertible into common equity other than pursuant to Company
employee equity plans.

         4.11. Delay of Registration and Suspension of Offering. If at any time
(a) after a request to effect a registration pursuant to Section 2 of this
Agreement or (b) after a Registration Statement has become effective, the
Company is engaged in any plan, proposal or agreement with respect to any
financing, acquisition, recapitalization, reorganization or other material
transaction or development the public disclosure of which would be would be
detrimental to the Company, then the Company may direct that such request be
delayed or that use of the prospectus contained in the Registration Statement be
suspended, as applicable, for a period of up to 30 days. The Company will notify
all Holders requesting the registration or all Selling Holders, as the case may
be, of the delay or suspension. In the case of notice suspending an effective
Registration Statement, each Selling Holder will immediately discontinue any
sales of Registrable Shares pursuant to such Registration Statement until such
Selling Holder has received copies of a supplemented or amended prospectus or
until such Selling Holder is advised in writing by the Company that the
then-current prospectus may be used and has received copies of any additional or
supplemental filings that are incorporated or deemed incorporated by reference
in such prospectus. The Company may exercise the rights provided by this Section
4.11 on only one occasion within any 365-day period.

         4.12. Participation by Selling Security Holders. In connection with the
preparation and filing of each Registration Statement, and before filing any
such Registration Statement or any other document in connection therewith, the
Company must give the participating Holders and their underwriters, if any, and
their respective counsel and accountants, the opportunity to participate in the
preparation of such Registration Statement, each prospectus included therein or
filed with the Commission, each amendment thereof or supplement thereto and any
related underwriting agreement or other document to be filed, and give each of
the aforementioned Persons such access to its books and records and such
opportunities to discuss the business of the Company with its officers and the
independent public accountants who have certified its financial statements as
shall be necessary, in the opinion of such Holders, underwriters, counsel or
accountants, to conduct a reasonable investigation within the meaning of the
Securities Act.

         4.13. Requests by Selling Holders. If requested by a Selling Holder,
the Company shall (i) as soon as practicable incorporate in a prospectus
supplement or post-effective amendment such information as a Selling Holder
reasonably requests to be included therein relating to the sale and distribution
of Registrable Shares, including, without limitation, information with respect
to the number of Registrable Shares being offered or sold, the purchase price
being paid therefor and any other terms of the offering of the Registrable
Shares to be sold in such other

                                      -8-
<PAGE>

offering provided that such information is required to be included in the
Registration Statement by the Securities Act; (ii) as soon as practicable make
all required filings of such prospectus supplement or post-effective amendment
after being notified of the matters to be incorporated in such prospectus
supplement or post-effective amendment; and (iii) as soon as practicable,
supplement or make amendments to any Registration Statement if reasonably
requested by a Selling Holder of such Registrable Shares.

         4.14. Stop Orders. The Company shall use its Best Efforts to prevent
the issuance of any stop order or other suspension of effectiveness of a
Registration Statement, or the suspension of the qualification of any of the
Registrable Shares for sale in any jurisdiction and, if such an order or
suspension is issued, to obtain the withdrawal of such order or suspension at
the earliest possible moment and to notify each Selling Holder of the issuance
of such order and the resolution thereof or its receipt of actual notice of the
initiation or threat of any proceeding for such purpose.

         4.15. Certificates. The Company shall reasonably cooperate with the
Selling Holders and, to the extent applicable, facilitate the timely preparation
and delivery of certificates representing the Registrable Shares to be offered
pursuant to a Registration Statement and enable such certificates to be in such
denominations or amounts, as the case may be, as the Selling Holders may
reasonably request and registered in such names as the Selling Holders may
request.

         4.16. Notice of Effectiveness. Within two business days after a
Registration Statement that includes the Registrable Shares is declared
effective by the Commission, the Company shall deliver, and shall cause legal
counsel for the Company to deliver, to the transfer agent for such Registrable
Shares (with copies to the Selling Holders) written confirmation that such
Registration Statement has been declared effective by the Commission.

         4.17. Governmental Approvals. The Company shall use its Best Efforts to
cause the Registrable Shares covered by the Registration Statement to be
registered with or approved by such other governmental agencies or authorities
as may be necessary to consummate the disposition of such Registrable Shares.

5. CERTAIN OTHER PROVISIONS.

         5.1. Additional Procedures. Selling Holders will take all such actions
and execute all such documents and instruments that are reasonably requested by
the Company to effect the sale of their shares in such Public Offering,
including, without limitation, being parties to the underwriting agreement
entered into by the Company and any other Selling Holders in connection
therewith; provided, however, that the aggregate amount of any liability of any
Selling Holder pursuant to such underwriting or other agreement will not exceed
such Selling Holder's net proceeds from such offering. In addition, each Selling
Holder will furnish to the Company such information regarding such Selling
Holder and the distribution proposed by such Selling Holder as the Company may
reasonably request in writing and as will be required in connection with any
registration, qualification or compliance referred to in Section 4.

                                      -9-
<PAGE>

         5.2. Underwriter's Cutback. Notwithstanding any other provision of this
Agreement, if the managing underwriter determines that the inclusion of all
shares requested to be registered in an underwritten offering would adversely
affect the offering, the Company may limit the number of Registrable Shares to
be included in the Registration Statement for such offering. If the registration
has been requested by the Holders pursuant to Section 2 hereof, the number of
shares that are entitled to be included in the registration and underwriting
will be reduced in the following manner: (a) first, shares of Company equity
securities, other than Registrable Shares, requested to be included in such
registration by shareholders will be excluded, (b) second, shares of Company
equity securities that the Company desires to include in such registration will
be excluded and (c) third, Registrable Shares requested to be included in such
registration by the Holders will be excluded. If the registration has been
initiated other than pursuant to Section 2 hereof, the number of shares that are
entitled to be included in the Registration Statement for such offering will be
reduced in the following manner: (x) first, shares of Company equity securities,
other than Registrable Shares, requested to be included in such registration by
shareholders will be excluded, (y) second, Registrable Shares requested to be
included in such registration by Holders will be excluded and (z) third, shares
of Company equity securities that the Company desires to include in such
registration will be excluded. To the extent that the underwriters do not deem
it necessary to exclude all of the shares requested to be registered by any
category of shareholders contemplated above, the number of shares that may be
included in the registration will be allocated to the members of such category
requesting registration in proportion, as nearly as practicable, to the
respective number of shares of Class A Common Stock (assuming conversion of any
convertible securities held by such shareholders) that they held at the time the
Company gives the notice specified in Section 2 or 3.

         5.3. Registration Expenses. The Company hereby agrees to pay all
Registration Expenses in connection with all registrations effected pursuant to
this Agreement. The Company, however, shall not be required to pay for any
expenses of a registration requested pursuant to Sections 2.1 or 2.2 hereof if
the registration request is withdrawn at any time at the request of Holders of a
majority of the Registrable Shares to be included in such registration (in which
case all Holders requesting such withdrawal shall bear such expenses). However,
if the requesting Holders have learned of information (other than information
known to them at the time they made their request) that, in the good faith
judgment of the requesting Holders, is reasonably likely to have a material
adverse effect on the business or prospects of the Company, then the Holders
shall not be required to pay any of such expenses in the case of a registration
requested pursuant to Section 2.1 or 2.2.

         5.4. Termination of Status as Registrable Shares. Registrable Shares
will cease to be Registrable Shares and cease to have the rights accorded to
such shares under this Agreement upon the earliest to occur of the following
events: (x) such shares shall have been sold pursuant to an effective
Registration Statement under the Securities Act or (y) such shares shall have
been sold pursuant to a transaction under Rule 144.

         5.5. Limitations on Subsequent Registration Rights. The Company will
not, without the prior written consent of Holders of at least a majority of the
Registrable Shares, enter into any agreements with any holder or prospective
holder of Company securities that grant such holder or prospective holder rights
to include securities of the Company in any Registration Statement, unless such
rights are subordinated to the rights granted to the Holders under this

                                      -10-
<PAGE>

Agreement, including, without limitation, by providing that (a) the holders of
such subordinated rights may not request a registration until at least 180 days
after the date on which the Holders can request a registration pursuant to
Section 2.1 and 2.2 and (b) the holders of such subordinated rights shall have
the number of shares of their Company securities requested to be included in a
Registration Statement reduced pursuant to any underwriters' cut-back provision
before the Holders suffer any reduction in the number of Registrable Shares that
they are permitted to include in such registration .

6. INDEMNIFICATION.

         6.1. Company Indemnification. In the event of any registration of any
of the Registrable Shares under the Securities Act pursuant to this Agreement,
then to the extent permitted by law, the Company will indemnify and hold
harmless each Selling Holder, its partners, directors and officers and each
other Person, if any, who controls such Selling Holder within the meaning of the
Securities Act or the Exchange Act (each such Person being a "Covered Person")
against any losses, claims, damages or liabilities, joint or several, to which
such Covered Person may become subject under the Securities Act, the Exchange
Act, state securities laws or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(a) any untrue statement or alleged untrue statement of any material fact
contained in any Registration Statement under which such Registrable Shares were
registered under the Securities Act, any preliminary or final prospectus
contained in the Registration Statement, or any amendment or supplement to such
Registration Statement or (b) the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading; and the Company will reimburse such Covered Person for
any legal or any other expenses reasonably incurred by such Covered Person in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable to
any Covered Person in any such case (x) to the extent that any such loss, claim,
damage or liability arises out of or is based upon any untrue statement or
omission made in such Registration Statement or prospectus, or any such
amendment or supplement, in reliance upon and in conformity with information
furnished to the Company, in writing, by or on behalf of such Covered Person
specifically for use in the preparation thereof or (y) in the case of a sale
directly by a Selling Holder (including a sale of such Registrable Shares
through any underwriter retained by such Selling Holder engaging in a
distribution solely on behalf of such Selling Holder), such untrue statement or
omission was contained in a preliminary prospectus and corrected in a final or
amended prospectus, and such Selling Holder failed to deliver a copy of the
final or amended prospectus at or prior to the confirmation of the sale of the
Registrable Shares to the person asserting any such loss, claim, damage or
liability in any case in which such delivery is required by the Securities Act.

         6.2. Seller Indemnification. In the event of any registration of any of
the Registrable Shares under the Securities Act pursuant to this Agreement, then
to the extent permitted by law, each Selling Holder will indemnify and hold
harmless the Company, each of its directors and officers and each Person (other
than such Selling Holder), if any, who controls the Company within the meaning
of the Securities Act or the Exchange Act, against any losses, claims, damages
or liabilities to which the Company, such directors and officers, or controlling
person may become subject under the Securities Act, Exchange Act, state
securities laws or otherwise,

                                      -11-
<PAGE>

insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon (a) any untrue statement of a material
fact contained in any Registration Statement under which such Registrable Shares
were registered under the Securities Act, any preliminary or final prospectus
contained in the Registration Statement, or any amendment or supplement to the
Registration Statement or (b) the omission to state a material fact required to
be stated therein or necessary to make the statements therein not misleading, if
the statement or omission was made in reliance upon and in conformity with
information furnished in writing to the Company by or on behalf of such Selling
Holder, specifically for use in connection with the preparation of such
Registration Statement, prospectus, amendment or supplement; provided, however,
that the obligations of such Selling Holder hereunder will be limited to an
amount equal to the net proceeds to such Selling Holder (after deducting all
underwriter's discounts and commissions and all other expenses paid by such
Holder in connection with the registration in question) from the disposition of
Registrable Shares pursuant to such registration.

         6.3. Notice of Claims, etc. Promptly after receipt by an indemnified
party of notice of the commencement of any action or proceeding involving a
claim of the type referred to in the foregoing provisions of this Section 6,
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party, give written notice to each such indemnifying party of
the commencement of such action; provided, however, that the failure of any
indemnified party to give such notice will not relieve such indemnifying party
of its obligations under this Section 6, except to the extent that such
indemnifying party is materially prejudiced by such failure. In case any such
action is brought against an indemnified party, each indemnifying party will be
entitled to participate in and to assume the defense thereof, jointly with any
other indemnifying party similarly notified, to the extent that it may wish,
with counsel reasonably satisfactory to such indemnified party, and (subject to
the following sentence) after notice from an indemnifying party to such
indemnified party of its election so to assume the defense thereof, such
indemnifying party will not be liable to such indemnified party for any legal or
other expenses subsequently incurred by the latter in connection with the
defense thereof. The indemnified party may participate in such defense at such
party's expense; provided, however, that the indemnifying party will pay such
expense if representation of such indemnified party by the counsel retained by
the indemnifying party would be inappropriate due to actual or potential
conflict of interests between the indemnified party and any other party
represented by such counsel in such proceeding; provided, further, that in no
event will the indemnifying party be required to pay the expenses of more than
one law firm as counsel for all indemnified parties pursuant to this sentence.
If, within 30 days after receipt of the notice, such indemnifying party has not
elected to assume the defense of the action, such indemnifying party will be
responsible for any legal or other expenses reasonably incurred by such
indemnified party in connection with the defense of the action, suit,
investigation, inquiry or proceeding. An indemnifying party may, in the defense
of any such claim or litigation, consent to the entry of a judgment or enter
into a settlement without the consent of the indemnified party only if such
judgment or settlement contains a general release of the indemnified party in
respect of such claims or litigation.

         6.4. Contribution. If the indemnification provided for in Sections 6.1
or 6.2 hereof is unavailable to a party that would have been an indemnified
party under any such Section in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to therein,
then each party that would have been an indemnifying party thereunder will, in
lieu of indemnifying such indemnified party, contribute to the amount paid or
payable by such

                                      -12-
<PAGE>

indemnified party as a result of such losses, claims, damages or liabilities (or
actions or proceedings in respect thereof) in such proportion as is appropriate
to reflect the relative fault of such indemnifying party on the one hand and
such indemnified party on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities (or
actions or proceedings in respect thereof). The relative fault will be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by such indemnifying party or
such indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The parties agree that it would not be just and equitable if contribution
pursuant to this Section 6.4 were determined by pro rata allocation or by any
other method of allocation that does not take account of the equitable
considerations referred to in the preceding sentence. The amount paid or payable
by a contributing party as a result of the losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to in this
Section 6.4 will include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) will be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

7. MISCELLANEOUS.

         7.1. Reports under the Exchange Act. With a view to making available to
the Holders the benefits of Rule 144 and any other rule or regulation of the
Commission that may at any time permit such Holder to sell securities of the
Company to the public without registration and with a view to making it possible
for Holders to register the Registrable Shares pursuant to a registration
statement on Form S-3, the Company agrees from the date hereof to use its best
efforts to:

                  (a) make and keep public information available, as those terms
         are understood and defined in Rule 144 under the Securities Act;

                  (b) file with the Commission in a timely manner all reports
         and other documents required of the Company under the Securities Act
         and the Exchange Act, so long as the Company remains subject to such
         requirements and the filing of such reports and other documents are
         required for the applicable provisions of Rule 144 to apply;

                  (c) file with the Commission in a timely manner all reports
         and other documents required of the Company under the Securities Act
         and the Exchange Act and take such other actions as will permit Holders
         to use Form S-3 for the resale of their Registrable Shares; and .

                  (d) furnish to any Holder forthwith upon request (i) a written
         statement by the Company as to its compliance with the reporting
         requirements of Rule 144, the Securities Act and the Exchange Act, or
         as to its qualification as a registrant whose securities may be resold
         pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy
         of the most recent annual or quarterly report of the Company and such
         other reports and documents so filed by the Company and (iii) such
         other information as may be reasonably requested

                                      -13-
<PAGE>

         in availing any Holder of any rule or regulation of the Commission that
         permits the selling of any such securities without registration or
         pursuant to such form.

         7.2. Transfer of Rights. The rights to cause the Company to register
Registrable Shares pursuant to Sections 2 and 3 may be assigned by any Holder to
a Permitted Transferee (as defined below), and by such Permitted Transferee to a
subsequent Permitted Transferee, but only if such rights are transferred (a) to
an affiliate or partner of such Holder or Permitted Transferee or a trustee or
an account managed or advised by a manager or adviser of such Holder or
Permitted Transferee or (b) in connection with the sale or other transfer of not
less than an aggregate of 100,000 Registrable Shares or some lesser number, if
such lesser number represents all the Registrable Shares then held by such
Holder. Any transferee to whom rights under this Agreement are transferred will
(x) as a condition to such transfer, deliver to the Company a written instrument
by which such transferee agrees to be bound by the obligations imposed upon
Holders under this Agreement to the same extent as if such transferee were a
Holder under this Agreement and (y) be deemed to be a Holder hereunder. Any
Person to whom rights under this Agreement are transferred in accordance with
this Section 7.2 shall be a "Permitted Transferee."

         7.3. Governing Law. This Agreement, the rights of the parties and all
claims, actions, causes of action, suits, litigation, controversies, hearings,
charges, complaints or proceedings arising in whole or in part under or in
connection herewith, will be governed by and construed in accordance with the
domestic substantive laws of the State of New York, without giving effect to any
choice or conflict of law provision or rule that would cause the application of
the laws of any other jurisdiction.

         7.4. Entire Agreement; Amendment and Waiver. This Agreement, together
with any documents, instruments and certificates explicitly referred to herein,
constitutes the entire agreement among the parties hereto with respect to the
subject matter hereof and supersedes any and all prior discussions,
negotiations, proposals, undertakings, understandings and agreements, whether
written or oral, with respect thereto. Any term of this Agreement may be amended
or terminated and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively) with the written consent of the Company and a Majority in
Interest of the Registrable Shares; provided, however, that any such amendment
or waiver treats all holders the same (without regard to any differences in
effect that such amendment or waiver may have on the Holders due to the
differing amounts of Registrable Shares held by such Holders). Any such
amendment, termination or waiver will be binding on all Holders.

         7.5. Notices. All notices, requests, demands, claims and other
communications required or permitted to be delivered, given or otherwise
provided under this Agreement must be in writing and must be delivered, given or
otherwise provided:
