                               HEALTHSPRING, INC.

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

     THIS AGREEMENT is made as of ____________________, 2006, between
HealthSpring, Inc., a Delaware corporation (the "Company"), and Kevin McNamara
("Executive"), and amends and restates in its entirety that certain Employment
Agreement between NewQuest, Inc. and Executive dated April 18, 2005 (the
"Original Employment Agreement").

     In consideration of the mutual covenants contained herein and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree to amend and restate the Original
Employment Agreement in its entirety as follows:.

     1. Employment. The Company shall employ Executive, and Executive hereby
accepts employment with the Company, upon the terms and conditions set forth in
this Agreement for the period beginning on the date hereof and ending as
provided in paragraph 4 hereof (the "Employment Period").

     2. Position and Duties.

          (a) During the Employment Period, Executive shall serve as the
Executive Vice President and Chief Financial Officer of the Company and shall
have the normal duties, responsibilities, functions and authority of the
Executive Vice President and Chief Financial Officer, subject to the power and
authority of the Company's Chief Executive Officer to expand or limit such
duties, responsibilities, functions and authority and to overrule actions of
officers of the Company. During the Employment Period, Executive shall render
such administrative, financial and other executive and managerial services to
the Company and its Subsidiaries which are consistent with Executive's position
as the Board may from time to time reasonably direct.

          (b) During the Employment Period, Executive shall report to the
Company's Chief Executive Officer and shall devote his full business time and
attention (except for permitted vacation periods and reasonable periods of
illness or other incapacity) to the business and affairs of the Company and its
Subsidiaries. Executive shall perform his duties, responsibilities and functions
to the Company and its Subsidiaries hereunder in good faith in a diligent,
trustworthy and professional manner and shall comply with the Company's and its
Subsidiaries' policies and procedures in all material respects. During the
Employment Period, Executive shall not serve as an officer or director of, or
otherwise perform services for compensation for, any other entity without the
prior written consent of the Board (which shall not be unreasonably withheld,
conditioned or delayed); provided that Executive may participate on boards of
charitable entities or other civic entities so long as such service does not
materially interfere with Executive's duties under this Agreement.

<PAGE>

          (c) For purposes of this Agreement, "Subsidiaries" shall mean any
corporation or other entity of which the securities or other ownership interests
having the voting power to elect a majority of the board of directors or other
governing body are, at the time of determination, owned by the Company, directly
or through one or more Subsidiaries.

     3. Compensation and Benefits.

          (a) During the Employment Period, Executive's base salary shall be
$350,000 per annum or such higher rate as the Board may determine from time to
time (as adjusted from time to time, the "Base Salary"), which salary shall be
payable by the Company or one of its Subsidiaries in regular installments in
accordance with such entity's general payroll practices (in effect from time to
time). In addition, during the Employment Period, Executive shall be entitled to
participate in all of the Company's employee benefit programs for which senior
executive employees of the Company and its Subsidiaries are generally eligible.
During the Employment Period, Executive shall also be entitled to five weeks of
paid vacation each calendar year in accordance with the Company's policies,
which if not taken during any year may not be carried forward, other than with
respect to one week per year, to any subsequent calendar year and no
compensation shall be payable in lieu thereof. The Company or one of its
affiliates or Subsidiaries shall obtain and maintain customary directors and
officers' liability insurance coverage covering Executive on terms reasonably
satisfactory to the Board.

          (b) In addition to the Base Salary, Executive shall be eligible for an
annual bonus in an amount up to 75% of the Base Salary then in effect following
the end of each fiscal year of the Company (ending December 31) based upon the
achievement by Executive and the Company and its Subsidiaries of budgetary and
other objectives set by the Compensation Committee of the Board; provided that
for the calendar year 2005, such bonus shall be paid on a pro rata basis based
upon that portion of the year that remained after April 18, 2005. Such bonus
shall be paid on or before March 15 of the following year.

          (c) During the Employment Period, the Company or one of its
Subsidiaries shall reimburse Executive for all reasonable business expenses
incurred by him in the course of performing his duties and responsibilities
under this Agreement which are consistent with the Company's and its
Subsidiaries' policies in effect from time to time with respect to travel,
entertainment and other business expenses, subject to the Company's and its
Subsidiaries' requirements with respect to reporting and documentation of such
expenses.

          (d) All amounts payable to Executive as compensation hereunder shall
be subject to all required and customary withholding by the Company.

     4. Term.

          (a) The Employment Period will continue until (i) Executive's
resignation, Disability (as defined in paragraph 4(f) below) or death, or (ii)
the Board decides to terminate Executive's employment with or without Cause (as
defined in paragraph 4(e) below). Except as otherwise provided herein, any
termination of the Employment Period by the Company shall be effective as
specified in a written notice from the Company to Executive.

          (b) If the Employment Period is terminated by the Company without
Cause or upon Executive's resignation with Good Reason, Executive shall be
entitled to (x) continue to receive his Base Salary payable in regular
installments and (y) continue to participate in employee benefit programs for
senior executive employees (other than bonus and incentive compensation plans),
at the Company's cost, to the extent permitted under the terms of such programs
and under applicable law, as special severance payments from the date of
termination for a period of twelve (12) months thereafter (the "Severance
Period") if and only if Executive has executed and delivered to the Company the
General Release substantially in form and substance as set forth in Exhibit A
attached hereto and the General Release has become effective, and only so long
as Executive has not revoked or breached the provisions of the General Release
or breached the provisions of paragraphs 5, 6 or 7 hereof and does not apply for
unemployment compensation chargeable to the Company or any Subsidiary during the
Severance Period, and Executive shall not be entitled to any other salary,
compensation or benefits after termination of the Employment Period, except as
specifically provided for in the Company's employee benefit plans or as
otherwise expressly required by applicable law. The amounts payable pursuant to
this paragraph 4(b) shall be payable in regular monthly installments; provided,
that, in the event the receipt of amounts payable pursuant to this paragraph
4(b) within six (6) months of the date of the Executive's termination would
cause the Executive to be subject to tax under Section 409A of the Internal
Revenue Code of 1986, as amended, then payment of such amounts shall be delayed
until the date that is six (6) months following Executive's termination date.
Unless Executive is terminated by the Company or its successor without Cause in
connection with a Sale of the Company (as defined below), the amounts payable
pursuant to this paragraph 4(b) shall be reduced by the amount of any
compensation Executive receives with respect to any other employment during the
Severance Period; provided that Executive shall have no duty or obligation to
seek other employment during the Severance Period or otherwise mitigate damages
hereunder. Upon request from time to time, Executive shall furnish the Company
with a true and complete certificate specifying any such compensation earned or
received by him during the Severance Period. For purposes of this Agreement,
"Sale of the Company" shall mean the sale of the Company to an Independent Third
Party or group of Independent Third Parties pursuant to which such party or
parties acquire (y) 50% or more of the common stock of the Company, par value
$.01 per share ("Common Stock") outstanding at the time of such transaction or
series of transactions or (z) all or substantially all of the Company's assets
determined on a consolidated basis. For purposes of this Agreement, "Independent
Third Party" shall mean any person who, immediately prior to the contemplated
transaction, does not own in excess of 5% of the Common Stock on a fully-diluted
basis (a "5% Owner"), who is not controlling, controlled by or under common
control with any such 5% Owner and who is not the spouse or descendant (by birth
or adoption) of any such 5% Owner or a trust for the benefit of such 5% Owner
and/or such other persons.


                                       -3-

<PAGE>

          (c) If the Employment Period is terminated by the Company for Cause or
is terminated pursuant to clause (a)(i) above (other than termination with Good
Reason), Executive shall only be entitled to receive his Base Salary through the
date of termination and shall not be entitled to any other salary, compensation
or benefits from the Company or any of its Subsidiaries thereafter, except as
otherwise specifically provided for under the Company's employee benefit plans
or as otherwise expressly required by applicable law.

          (d) Except as otherwise expressly provided herein, all of Executive's
rights to salary, bonuses, employee benefits and other compensation hereunder
which would have accrued or become payable after the termination of the
Employment Period shall cease upon such termination, other than those expressly
required under applicable law (such as COBRA). The Company may offset any
amounts Executive owes the Company or any of its Subsidiaries against any
amounts the Company or any of its Subsidiaries owes Executive hereunder.

          (e) For purposes of this Agreement, "Cause" shall mean with respect to
Executive one or more of the following: (i) the conviction of a felony or other
crime involving moral turpitude or the commission of any other act or omission
involving material dishonesty or fraud with respect to the Company or any of its
Subsidiaries, (ii) reporting to work under the influence of illegal drugs, the
use of illegal drugs (whether or not at the workplace) or other repeated conduct
causing the Company or any of its Subsidiaries substantial public disgrace or
disrepute or substantial economic harm, which is not cured within 20 days
following written notice thereof to the Executive, (iii) material and repeated
failure to perform his duties as reasonably directed by the Board or the
Company's Chief Executive Officer, which is not cured within 20 days following
written notice thereof to the Executive, (iv) breach of fiduciary duty or
engaging in gross negligence or willful misconduct with respect to the Company
or any of its Subsidiaries or (v) any other material breach of this Agreement
which is not cured within 20 days after written notice thereof to Executive.

          (f) For purposes of this Agreement, "Disability" shall mean the
disability of Executive caused by any physical or mental injury, illness or
incapacity as a result of which Executive is unable to effectively perform or
fails to perform the essential functions of Executive's duties for 90
consecutive days or 120 days during any 12-month period.

          (g) For purposes of this Agreement, "Good Reason" shall mean if
Executive resigns from employment with the Company and its Subsidiaries prior to
the end of the Employment Period as a result of one or more of the following
reasons: (i) the Company reduces the amount of the Base Salary, (ii) the Company
materially reduces his responsibilities, in each case which is not cured within
20 days after written notice thereof to the Company, (iii) the relocation of the
Company's principal executive offices and/or the location at which Executive
provides services pursuant to this Agreement to a location outside the
metropolitan Nashville, Tennessee area, or (iv) the Company's material breach of
this Agreement; provided that written notice of Executive's resignation for Good
Reason must be delivered to the Company within 45 days after the occurrence of
any such event in order for Executive's resignation with Good Reason to be
effective hereunder.

     5. Confidential Information.

          (a) Executive acknowledges that the information, observations and data
(including trade secrets) obtained by him while employed by the Company and its
Subsidiaries concerning the business or affairs of the Company or any Subsidiary
("Confidential Information") are the property of the Company or such Subsidiary.
Therefore, Executive agrees that, except as set forth in, and pursuant to, this
paragraph 5(a), he shall not disclose to any unauthorized person or entity or
use for his own purposes any Confidential Information or any confidential or
proprietary information of other persons or entities in the possession of the
Company and its Subsidiaries ("Third Party Information"), without the prior
written consent of the Board, unless and to the extent that the Confidential
Information or Third Party Information becomes generally known to and available
for use by the public other than as a result of Executive's acts or omissions.
In the event that Executive is requested or required (by oral question or
request for information or documents in any legal proceeding, interrogatory,
subpoena, civil investigative demand, or similar process) to disclose any
Confidential Information, such Executive shall notify the Company promptly of
the request or requirement so that the Company may seek an appropriate
protective order or waive compliance with the provisions of this Section. If, in
the absence of a protective order or the receipt of a waiver hereunder,
Executive is, on the advice of counsel, compelled to disclose any Confidential
Information to any tribunal, such Executive may disclose the Confidential
Information to the tribunal; provided that such disclosing Executive shall use
its reasonable best efforts to assist the Company to obtain, at the request of
the Company (and at the Company's sole expense), an order or other assurance
that confidential treatment shall be accorded to such portion of the
Confidential Information required to be disclosed as the Company shall
designate. Executive shall deliver to the Company at the termination of the
Employment Period, or at any other time the Company may request, all memoranda,
notes, plans, records, reports, computer files, disks and tapes, printouts and
software and other documents and data (and copies thereof) embodying or relating
to Third Party Information, Confidential Information, Work Product (as defined
below) or the business of the Company or any of its Subsidiaries which he may
then possess or have under his control.

          (b) Executive shall be prohibited from using or disclosing any
confidential information or trade secrets that Executive may have learned
through any prior employment. If at any time during this employment with the
Company or any Subsidiary, Executive believes he is being asked to engage in
work that will, or will be likely to, jeopardize any confidentiality or other
obligations Executive may have to former employers, Executive shall immediately
advise the Chief Executive Officer and Chief Operating Officer so that
Executive's duties can be modified appropriately. Executive represents and
warrants to the Company that Executive took nothing with him which belonged to
any former employer when Executive left his prior position and that Executive
has nothing that contains any information which belongs to any former employer.
If at any time Executive discovers this is incorrect, Executive shall promptly
return any such materials to Executive's former employer. The Company does not
want any such materials, and Executive shall not be permitted to use or refer to
any such materials in the performance of Executive's duties hereunder.


                                       -5-

     6. Intellectual Property, Inventions and Patents. Executive acknowledges
that all discoveries, concepts, ideas, inventions, innovations, improvements,
developments, methods, designs, analyses, drawings, reports, patent
applications, copyrightable work and mask work (whether or not including any
Confidential Information) and all registrations or applications related thereto,
all other proprietary information and all similar or related information
(whether or not patentable) which relate to the Company's or any of its
Subsidiaries' actual or anticipated business, research and development or
existing or future products or services and which are conceived, developed or
made by Executive (whether alone or jointly with others) while employed by the
Company and its Subsidiaries, whether before or after the date of this Agreement
("Work Product"), belong to the Company or such Subsidiary. Executive shall
promptly disclose all patentable inventions and other material Work Product to
the Board and, at the Company's expense, perform all actions reasonably
requested by the Board (whether during or after the Employment Period) to
establish and confirm such ownership (including, without limitation,
assignments, consents, powers of attorney and other instruments). Executive
acknowledges that all Work Product shall be deemed to constitute "works made for
hire" under the U.S. Copyright Act of 1976, as amended.

     In accordance with Title 19, Section 805 of the Delaware Code, Executive is
hereby advised that this paragraph 6 regarding the Company's and its
Subsidiaries' ownership of Work Product does not apply to any invention for
which no equipment, supplies, facilities or trade secret information of the
Company or any Subsidiary was used and which was developed entirely on
Executive's own time, unless (i) the invention relates to the business of the
Company or any Subsidiary or to the Company's or any Subsidiaries' actual or
demonstrably anticipated research or development or (ii) the invention results
from any work performed by Executive for the Company or any Subsidiary.

     7. Non-Compete, Non-Solicitation.

          (a) In further consideration of the compensation to be paid to
Executive hereunder, Executive acknowledges that during the course of his
employment with the Company and its Subsidiaries he shall become familiar with
the Company's and its Subsidiaries' trade secrets and with other Confidential
Information concerning the Company and its predecessors and Subsidiaries and
that his services have been and shall continue to be of special, unique and
extraordinary value to the Company and its Subsidiaries and therefore Executive
agrees that, during the Employment Period and for eighteen months thereafter
(the "Noncompete Period"), he shall not directly or indirectly own any interest
in, manage, control, participate in, consult with, render services for, be
employed in an executive, managerial or administrative capacity by, or in any
manner engage in any business competing with the businesses of the Company or
its Subsidiaries, as such businesses exist during the Employment Period or, as
of the date of termination of the Employment Period, are contemplated to exist
during the eighteen-month period following the date of termination of the
Employment Period (the "Restricted Business") within any geographical area in
which the Company or any of its Subsidiaries engage or plan to engage during the
eighteen-month period following the date of termination of the Employment
Period. Nothing herein shall prohibit Executive from (i) being a passive owner
of not more than 2% of the outstanding stock of any class of a corporation which
is publicly traded, so long as Executive has no active participation in the
business of such corporation or (ii) becoming


                                       -6-

<PAGE>

employed, engaged, associated or otherwise participating with a separately
managed division or Subsidiary of a competitive business that does not engage in
the Restricted Business (provided that services are provided only to such
division or Subsidiary).

          (b) During the Noncompete Period, Executive shall not directly or
indirectly through another person or entity (i) induce or attempt to induce any
employee of the Company or any Subsidiary to leave the employ of the Company or
such Subsidiary, or in any way interfere with the relationship between the
Company or any Subsidiary and any employee thereof, (ii) hire any person who was
an employee of the Company or any Subsidiary at any time during the 18-month
period immediately prior to the termination of the Employment Period or (iii)
induce or attempt to induce any customer, supplier, licensee, licensor,
franchisee or other business relation of the Company or any Subsidiary to cease
doing business with the Company or such Subsidiary, or in any way interfere with
the relationship between any such customer, supplier, licensee or business
relation and the Company or any Subsidiary (including, without limitation,
making any negative or disparaging statements or communications regarding the
Company or its Subsidiaries). Notwithstanding the foregoing, nothing in this
Agreement shall prohibit Executive from employing an individual (i) with the
consent of the Company or (ii) who responded to general solicitations in
publications or on websites, or through the use of search firms, so long as such
general solicitations or search firm activities are not targeted specifically at
an employee of the Company or any of its Subsidiaries. In addition, nothing in
this Agreement will prohibit the making of any truthful statements made by any
Person in response to a lawful subpoena or legal proceeding or to enforce such
Person's rights under this Agreement, or any other agreement between Executive,
the Company and its Subsidiaries.

     8. Enforcement. If, at the time of enforcement of paragraph 5, 6 or 7 of
this Agreement, a court holds that the restrictions stated herein are
unreasonable under circumstances then existing, the parties hereto agree that
the maximum period, scope or geographical area reasonable under such
circumstances shall be substituted for the stated period, scope or area and that
the court shall be allowed to revise the restrictions contained herein to cover
the maximum period, scope and area permitted by law. Because Executive's
services are unique and because Executive has access to Confidential Information
and Work Product, the parties hereto agree that the Company and its Subsidiaries
would suffer irreparable harm from a breach of paragraph 5, 6 or 7 by Executive
and that money damages would not be an adequate remedy for any such breach of
this Agreement. Therefore, in the event a breach or threatened breach of this
Agreement, the Company or its successors or assigns, in addition to other rights
and remedies existing in their favor, shall be entitled to specific performance
and/or injunctive or other equitable relief from a court of competent
jurisdiction in order to enforce, or prevent any violations of, the provisions
hereof (without posting a bond or other security). In addition, in the event of
a breach or violation by Executive of paragraph 7, the Noncompete Period shall
be automatically extended by the amount of time between the initial occurrence
of the breach or violation and when such breach or violation has been duly
cured. Executive acknowledges that the restrictions contained in paragraph 7 are
reasonable and that he has reviewed the provisions of this Agreement with his
legal counsel.

     9. Executive's Representations. Executive hereby represents and warrants to
the Company that (i) the execution, delivery and performance of this Agreement
by Executive do not


                                       -7-

<PAGE>

and shall not conflict with, breach, violate or cause a default under any
contract, agreement, instrument, order, judgment or decree to which Executive is
a party or by which he is bound, (ii) Executive is not a party to or bound by
any employment agreement, noncompete agreement or confidentiality agreement with
any other person or entity, except for that certain Non-Competition Agreement,
which shall remain in full force and effect after the date hereof until the
termination of such agreement in accordance with the terms thereof, and (iii)
upon the execution and delivery of this Agreement by the Company, this Agreement
shall be the valid and binding obligation of Executive, enforceable in
accordance with its terms. Executive hereby acknowledges and represents that he
has consulted with independent legal counsel regarding his rights and
obligations under this Agreement and that he fully understands the terms and
conditions contained herein. The Company hereby represents and warrants to
Executive that (i) the execution, delivery and performance of this Agreement by
the Company do not and shall not conflict with, breach, violate or cause a
default under any contract, agreement, instrument, order, judgment or decree to
which the Company is a party or by which it is bound and (ii) upon the execution
and delivery of this Agreement by Executive, this Agreement shall be the valid
and binding obligation of the Company, enforceable in accordance with its terms.

     10. Survival. Paragraphs 4 through 24, inclusive, shall survive and
continue in full force in accordance with their terms notwithstanding the
expiration or termination of the Employment Period.

     11. Notices. Any notice provided for in this Agreement shall be in writing
and shall be either personally delivered, sent by reputable overnight courier
service or mailed by first class mail, return receipt requested, to the

     12. Severability. Whenever possible, each provision of this Agreement shall

jurisdiction, such invalidity, illegality or unenforceability shall not affect

                                       -9-

<PAGE>

Delaware or any other jurisdiction) that would cause the application of the laws
of any jurisdiction other than the State of Delaware.

     18. Amendment and Waiver. The provisions of this Agreement may be amended
or waived only with the prior written consent of the Company (as approved by the
Board) and Executive, and no course of conduct or course of dealing or failure

                                 GENERAL RELEASE


     I, Kevin McNamara, in consideration of and subject to the performance by
HealthSpring, Inc., a Delaware corporation (together with its Subsidiaries, the
"Company"), of its obligations under the Amended and Restated Employment
Agreement, dated as of _________, 2006 (the "Agreement"), do hereby release
and forever discharge as of the date hereof the Company and its affiliates and
all present and former directors, officers, agents, representatives, employees,
successors and assigns of the Company and its affiliates and the Company's
direct or indirect owners (collectively, the "Released Parties") to the extent
provided below.


1.   I understand that any payments or benefits paid or granted to me under
     paragraph 4(b) of the Agreement represent, in part, consideration for
     signing this General Release and are not salary, wages or benefits to which
     I was already entitled. I understand and agree that I will not receive the
     payments and benefits specified in paragraph 4(b) of the Agreement unless I
     execute this General Release and do not revoke this General Release within
     the time period permitted hereafter or breach this General Release. Such
     payments and benefits will not be considered compensation for purposes of
     any employee benefit plan, program, policy or arrangement maintained or
     hereafter established by the Company or its affiliates. I also acknowledge
     and represent that I have received all payments and benefits that I am
     entitled to receive (as of the date hereof) by virtue of any employment by
     the Company.

2.   Except as provided in paragraph 4 below and except for the provisions of my
     Employment Agreement which expressly survive the termination of my
     employment with the Company, I knowingly and voluntarily (for myself, my
     heirs, executors, administrators and assigns) release and forever discharge
     the Company and the other Released Parties from any and all claims, suits,
     controversies, actions, causes of action, crossclaims, counterclaims,
     demands, debts, compensatory damages, liquidated damages, punitive or
     exemplary damages, other damages, claims for costs and attorneys' fees, or
     liabilities of any nature whatsoever in law and in equity, both past and
     present (through the date this General Release becomes effective and
     enforceable) and whether known or unknown, suspected, or claimed against
     the Company or any of the Released Parties which I, my spouse, or any of my
     heirs, executors, administrators or assigns, may have, which arise out of
     or are connected with my employment with, or my separation or termination
     from, the Company (including, but not limited to, any allegation, claim or
     violation, arising under: Title VII of the Civil Rights Act of 1964, as
     amended; the Civil Rights Act of 1991; the Age Discrimination in Employment
     Act of 1967, as amended (including the Older Workers Benefit Protection
     Act); the Equal Pay Act of 1963, as amended; the Americans with
     Disabilities Act of 1990; the Family and Medical Leave Act of 1993; the
     Worker Adjustment Retraining and Notification Act; the Employee Retirement
     Income Security Act of 1974; any applicable Executive Order Programs; the
     Fair Labor Standards Act; or their state or local counterparts; or under
     any other federal, state or local civil or human rights law, or under any
     other local, state, or federal law, regulation or ordinance; or under any
     public policy, contract or tort, or under common


                                      ExB-1

<PAGE>

     law; or arising under any policies, practices or procedures of the Company;
     or any claim for wrongful discharge, breach of contract, infliction of
     emotional distress, defamation; or any claim for costs, fees, or other
     expenses, including attorneys' fees incurred in these matters) (all of the
     foregoing collectively referred to herein as the "Claims").

3.   I represent that I have made no assignment or transfer of any right, claim,
     demand, cause of action, or other matter covered by paragraph 2 above.

4.   I agree that this General Release does not waive or release any rights or
     claims that I may have under the Age Discrimination in Employment Act of
     1967 which arise after the date I execute this General Release. I
     acknowledge and agree that my separation from employment with the Company
     in compliance with the terms of the Agreement shall not serve as the basis
     for any claim or action (including, without limitation, any claim under the
     Age Discrimination in Employment Act of 1967).

5.   In signing this General Release, I acknowledge and intend that it shall be
     effective as a bar to each and every one of the Claims hereinabove
     mentioned or implied. I expressly consent that this General Release shall
     be given full force and effect according to each and all of its express
     terms and provisions, including those relating to unknown and unsuspected
     Claims (notwithstanding any state statute that expressly limits the
     effectiveness of a general release of unknown, unsuspected and
     unanticipated Claims), if any, as well as those relating to any other
     Claims hereinabove mentioned or implied. I acknowledge and agree that this
     waiver is an essential and material term of this General Release and that
     without such waiver the Company would not have agreed to the terms of the
     Agreement. I further agree that in the event I should bring a Claim seeking
     damages against the Company, or in the event I should seek to recover
     against the Company in any Claim brought by a governmental agency on my
     behalf, this General Release shall serve as a complete defense to such
     Claims. I further agree that I am not aware of any pending charge or
     complaint of the type described in paragraph 2 as of the execution of this
     General Release.

6.   I agree that neither this General Release, nor the furnishing of the
     consideration for this General Release, shall be deemed or construed at any
     time to be an admission by the Company, any Released Party or myself of any
     improper or unlawful conduct.

7.   I agree that I will forfeit all amounts payable by the Company pursuant to
     the Agreement if I challenge the validity of this General Release. I also
     agree that if I violate this General Release by suing the Company or the
     other Released Parties, I will pay all costs and expenses of defending
     against the suit incurred by the Released Parties, including reasonable
     attorneys' fees, and return all payments received by me pursuant to the
     Agreement.

8.   I agree that this General Release is confidential and agree not to disclose
     any information regarding the terms of this General Release, except to my
     immediate family and any tax, legal or other counsel I have consulted
     regarding the meaning or effect hereof or as required by law, and I will
     instruct each of the foregoing not to disclose the same to


                                      ExB-2

<PAGE>

     anyone. Notwithstanding anything herein to the contrary, each of the
     parties (and each affiliate and person acting on behalf of any such party)
     agree that each party (and each employee, representative, and other agent
     of such party) may disclose to any and all persons, without limitation of
     any kind, the tax treatment and tax structure of this transaction
     contemplated in the Agreement and all materials of any kind (including
     opinions or other tax analyses) that are provided to such party or such
     person relating to such tax treatment and tax structure, except to the
     extent necessary to comply with any applicable federal or state securities
     laws. This authorization is not intended to permit disclosure of any other
     information including (without limitation) (i) any portion of any materials
     to the extent not related to the tax treatment or tax structure of this
     transaction, (ii) the identities of participants or potential participants
     in the Agreement, (iii) any financial information (except to the extent
     such information is related to the tax treatment or tax structure of this
     transaction), or (iv) any other term or detail not relevant to the tax
     treatment or the tax structure of this transaction.

9.   Any non-disclosure provision in this General Release does not prohibit or
     restrict me (or my attorney) from responding to any inquiry about this
     General Release or its underlying facts and circumstances by the Securities
     and Exchange Commission (SEC), the National Association of Securities
     Dealers, Inc. (NASD), any other self-regulatory organization or
     governmental entity.

10.  I agree to reasonably cooperate with the Company in any internal
     investigation, any administrative, regulatory, or judicial proceeding or
     any dispute with a third party on the terms and subject to the limitations
     set forth in paragraph 24 of the Agreement.

11.  I agree not to disparage the Company, its past and present investors,
     officers, directors or employees or its affiliates and to keep all
     confidential and proprietary information about the past or present business
     affairs of the Company and its affiliates confidential in accordance with
     the terms of the Agreement unless a prior written release from the Company
     is obtained. I further agree that as of the date hereof, I have returned to
     the Company any and all property, tangible or intangible, relating to its
     business, which I possessed or had control over at any time (including, but
     not limited to, company-provided credit cards, building or office access
     cards, keys, computer equipment, manuals, files, documents, records,
     software, customer data base and other data) and that I shall not retain
     any copies, compilations, extracts, excerpts, summaries or other notes of
     any such manuals, files, documents, records, software, customer data base
     or other data.

12.  Notwithstanding anything in this General Release to the contrary, this
     General Release shall not relinquish, diminish, or in any way affect (i)
     any rights or claims arising out of any breach by the Company or by any
     Released Party of the Agreement after the date hereof, (ii) any rights or
     obligations under applicable law which cannot be waived or released
     pursuant to an agreement, (iii) any rights to payments or benefits under
     paragraph 4(b) of the Agreement, (iv) my rights of indemnification and
     directors and officers insurance coverage to which I may be entitled solely
     with regards to my service as an officer or director of the Company; (v) my
     rights with regard to accrued benefits under any employee benefit plan,
     policy or arrangement maintained by the Company or


                                      ExB-3

<PAGE>

     under COBRA; and (vi) my rights as a stockholder or other equityholder of
     the Company and/or its affiliates.

13.  Whenever possible, each provision of this General Release shall be
     interpreted in, such manner as to be effective and valid under applicable
     law, but if any provision of this General Release is held to be invalid,
     illegal or unenforceable in any respect under any applicable law or rule in
     any jurisdiction, such invalidity, illegality or unenforceability shall not
     affect any other provision or any other jurisdiction, but this General
     Release shall be reformed, construed and enforced in such jurisdiction as
     if such invalid, illegal or unenforceable provision had never been
     contained herein.
