EXHIBIT B10

            EMPLOYMENT, CONFIDENTIALITY AND NONCOMPETITION AGREEMENT

      This Employment, Confidentiality and Noncompetition Agreement (the
"Agreement") is made and entered into as of this 1st day of August, 2000 by and
between MEDIQUIK SERVICES, INC., a Delaware corporation ("Employer"), and GRANT
M. GABLES ("Employee").

      In consideration of the mutual promises and covenants contained in this
Agreement, the receipt and legal sufficiency of which consideration are hereby
acknowledged, the parties hereby agree as follows:

            1. Duties. Employer shall employ Employee and Employee shall work
for Employer in the employment position described in Exhibit A attached, which
is by this reference incorporated into and made a part of this Agreement. In
this position, Employee shall perform all assigned duties, comply with all
employment policies, and willingly obey all responsible rules, regulations and
special instructions that now exist or that may in the future be established by
Employer from time to time. Employee shall render such services and perform such
duties at such places or in such areas or territories as Employer shall direct,
provided however, that if Employer relocates Employee from Houston, Texas
without the concurrence of Employee, such action by Employer shall, at the
option of Employee, constitute a termination of Employee by Employer without
cause.

            2. Employee Performance. Employee accepts employment with Employer
on the terms and conditions provided in this Agreement. Employee recognizes that
Employee owes to Employer duties of loyalty, fidelity and obedience in all
matters pertaining to such employment. Employee shall serve Employer diligently
and faithfully, shall timely perform all duties to the best of Employee's
ability and in compliance with Employer's reasonable standards of performance,
and shall devote Employee's full time and best efforts to the conduct of
Employer's business. Employee warrants that all information provided by Employee
is true and correct.

            3. Compensation. In consideration for the services of Employee
rendered to Employer pursuant to the terms of this Agreement, and subject to the
full performance of the Employee's obligations hereunder, Employer shall pay
Employee according to the provisions of Employer's compensation plan as
described in Exhibit A. Employee shall receive no compensation or benefits,
including but not limited to paid holidays, paid vacation and paid health
insurance, that are not set forth in Exhibit A.

            4. Employment.

                  A. Term of Employment. Employee's term of employment under
this Agreement shall commence on August 1st, 2000 and shall continue until the
same date two years later unless prior to that date (a) Employer, for "Cause"
(as defined below), terminates Employer's employment of employee, or (b)
Employer and Employee mutually agree to the termination or extension of
Employee's employment, in writing signed by both of them in accordance with
Section 9(g) of this Agreement. (c) there occurs one of the four following
events the occurrence of which shall be considered a termination without cause:
1) a merger in which the Employer is not the surviving entity, 2) a sale of
substantially all of the assets of Company, 3) a transaction or series of
transactions pursuant to which the Employer adopts a plan of dissolution or
liquidation, or 4) any other organization, consolidation or transaction in which
current owners no longer maintain either voting control or the ability to elect
a

<PAGE>

majority of the directors of the Employer (post MiraQuest transaction), (d)
Employee provides Employer one hundred and eighty (180) days notice of his
intention to terminate his employment with Employer, or (e) Employee becomes
disabled thus impairing his ability to perform his duties, which condition shall
be treated as a termination without cause and the pay and benefits associated
with termination without cause shall apply. In the event of Employee's giving
notice of intent to resign, the Employer has the choice of releasing Employee of
his duties and obligations and continuing his compensation and benefits for the
one hundred and eighty (180) day period or requiring Employee to continue his
duties and meeting his obligations as an Employee until the expiration of the
one hundred and eighty (180) day period.

                  B. Termination of Employment. During the term of this
Agreement, the Employer may terminate the employment of the Employee for "Cause"
by giving the Employee written notice of such termination setting forth the
"Cause" relied upon. For the purposes of this Agreement, "Cause" shall include
but not be limited to (i) the Employee's disregard of lawful instructions of the
Employer that are consistent with the Employee's position and duties set forth
herein; (ii) the Employee's failure to perform Employee's duties in compliance
with Employer's reasonable standards of performance and not as a result of
notice of intention to resign, disability or retirement; (iii) the Employee's
willful actions which do or are likely to result unjustifiably in material
damage or embarrassment to the Employer, the Employer's reputation, or the
Employer's other legitimate business interests; (iv) the Employee's abuse or
illegal use of alcohol other drugs or controlled substances; (v) the Employee's
material breach of any of the terms or conditions of the Agreement; (vi) the
conviction of the Employee of a felony or entry of a guilty plea or plea of nolo
contendere by Employee to a felony (or any other crime that has or might have a
material adverse effect upon Employee's ability to carry out Employee's job
duties or other obligations under this Agreement); or (vii) the Employee's
theft, embezzlement or misappropriation of funds from the Employer. In the event
Employer wishes to terminate Employee's employment pursuant to Subsection (i),
(ii), (iv), or (v) above, Employer shall give to Employee thirty (30) days'
notice of Employer's intention to terminate Employee's employment and the
reason(s) for such termination. If Employee wishes to remain employed by
Employer, Employee shall during such thirty (30) day period remedy to the
reasonable satisfaction of Employer's Board of Directors the misconduct,
disregard, abuse, or other breach specified in such notice. If Employee does not
so remedy such breach to the reasonable satisfaction of Employer's Board of
Directors, then the termination shall take effect at the end of the thirty (30)
day period. A termination pursuant to Subsection (vi) or (vii) shall take effect
immediately upon the giving of notice. Achievement of desired results or
performance established as a goal by the Employer shall not be a basis of
termination for Cause. Any benefits or compensation to be earned based on
performance criteria will terminate with employee's termination whether with or
without cause.

                  C. Termination without Cause. Employer may terminate the
Employee's employment without Cause at any time within the Employee's first 120
days of employment upon payment to Employee of severance compensation equivalent
to compensation for 210 days of employment reduced by the compensation paid to
Employee through the date of termination. After Employee has been employed and
paid for the excess of 120 days, Employer may terminate the employment of the
Employee without Cause upon payment to Employee of severance compensation
equivalent to compensation for six (6) months, including all benefits. Equity
compensation is not included as component of the termination without cause
severance compensation calculation.

                  D. Equal Opportunity Employer. Employer is an Equal Employment
Opportunity organization and shall not discriminate against Employee on the
basis of age, color, creed, disability, marital status, national origin,
political ideology, race, religion, sex, sexual orientation, or status as a
disabled veteran or veteran of the Vietnam war era, with respect to promotion,
transfer, compensation benefits or any other employment decision.

<PAGE>

                  E. Work Environment. In addition, Employer is committed to
maintaining a positive, constructive working environment and will not tolerate
harassment or abuse of Employee in the workplace. If Employee feels Employee has
been subject to discrimination, harassment or abuse of Employee in connection
with Employee's employment, Employer encourages Employee to bring any and all
such matters to the attention of Employer's chief human resources officer and/or
Board of Directors, who will conduct an investigation of all such matters
brought to their attention and take such personnel action as is appropriate
under the circumstances. Employee will not be subjected to retaliation for
submitting complaints to Employer's chief human resources officer and/or Board
of Directors.

            5. Confidential Information.

                  A. Definition of Confidential Information. Employer is in the
business of providing chronic disease management services and other related
services, and Employer has built up an established and extensive trade and
reputation in the industry . Employer has developed and continues to develop
commercially valuable technical and non-technical information ("Confidential
Information") that is proprietary and confidential and/or constitutes Employer's
"trade secrets" as defined by the Texas Trade Secrets Act. Such Confidential
Information, which is vital to the success of Employer's business, includes, but
is not necessarily limited to: programs, computer programs, system
documentation, data compilations, manuals, methods, techniques, processes,
patented and/or unpatented technology, research, know-how, development, designs,
devices, inventions, the identities of customers, prospective customers,
suppliers and prospective suppliers, contracts with suppliers and customers,
sales proposals, methods of sales, marketing research and data, pricing
policies, cost information, financial information, business plans, specialized
requests of Employer's customers, and other materials and documents developed by
Employer. Confidential Information also includes special hardware, product
hardware, related software and related documentation, either owned by Employer
or in Employer's possession under an agreement of nondisclosure. Through
Employee's employment, Employee may become acquainted with or contribute to the
Employer's Confidential Information through inventions, discoveries,
improvement, software development, and/or in other ways.

                  B. Employee Access to Confidential Information. Employee shall
(a) access only such Confidential Information as is reasonably necessary to
perform Employee's job functions, and (b) allow access to Confidential
Information under Employee's control to only those of Employee's co-employees
whose job functions for Employer reasonably necessitate access to such
Confidential Information.

                  C. Nondisclosure of Confidential Information. Employee shall
not, at any time, either during or subsequent to employment, directly or
indirectly, appropriate, disclose or divulge any Confidential Information to any
person not then employed by Employer, unless authorized or directed to do so by
Employer or required to do so by a court or other governmental entity acting
with the force of law. If Employer authorizes or directs Employee to disclose
Confidential Information to any third party, Employee must ensure that a signed
confidentiality agreement for the benefit of Employer is or has been obtained
from the third party to whom Confidential Information is being disclosed and
that all Confidential Information so disclosed is clearly marked "Confidential."

                  D. Return of Confidential and Other Information. All
Confidential Information provided to Employee, and all documents and things
prepared by Employee in the course of Employee's employment, including but not
necessarily limited to correspondence, drawings, blueprints, manuals, letters,
notes, lists, reports, flow-charts, computer programs, proposals, notebooks,
DayTimers, planners, calendars, schedules, discs, data tapes, financial plans
and information, business plans, and other documents and records, whether in
hard copy, magnetic media or otherwise, and any and all copies

<PAGE>

thereof, are the exclusive property of Employer and shall be returned
immediately to Employer upon termination of employment or upon Employer's
request at any time.

                  E. Ownership of Confidential Information. Employee hereby
grants to Employer, and Employer hereby accepts, the entire right, title, and
interest of Employee in and to any of the Confidential Information created or
developed by Employee, or that may be created or developed by Employee during
the term of the Employee's employment by Employer (whether created or developed
within or outside the course and scope of Employee's employment by Employer),
including, but not limited to, all patents, copyrights, trade secrets, and other
proprietary rights in or based on the Confidential Information. If the
Confidential Information or any portion thereof is copyrightable, it shall be
deemed to be a "work made for hire," as such term is defined in the copyright
laws of the United States. Employee shall cooperate with Employer or its
designees and execute assignments, oaths, declarations, and other documents
prepared by Employer, to effect the terms of this Section 5(E) or to perfect or
enforce any proprietary rights resulting from or related to this Agreement. Such
cooperation and execution shall be at no additional compensation to Employee;
provided, however, Employer shall reimburse Employee for reasonable
out-of-pocket expenses incurred at the specific request of Employer.

            6. Noncompetition Obligations. During the term of Employee's
employment with Employer, and for a 12 month period of time following
termination of such employment for any reason, Employee will not, directly or
indirectly, at any place in the United States, either for him/herself or on
behalf of any other person, partnership, corporation or other entity:

                  (a)   solicit, divert, take away, or attempt to solicit,
                        divert or take away, any of Employer's customers or the
                        business or patronage of any such customer;

                  (b)   solicit, recruit or hire any other employee of Employer;
                        or

                  (c)   otherwise engage or become interested (as owner,
                        stockholder, partner, director, officer, member,
                        creditor, consultant, or employee) in any business in
                        competition with any portion of the business conducted
                        by Employer at any time during Employee's employment
                        with Employer unless such activity is set forth in
                        Exhibit B as an activity in which Employee is engaged on
                        the Effective Date of this Agreement is initiated.

Employee acknowledges that Employer is doing business throughout the United
States, that Employee is reasonably expected to have contact with Employer's
customers throughout the United States during the term of Employee's employment
with Employer, and that the national geographic scope of these covenants is
reasonably necessary to protect Employer's legitimate business interests.

            7. Enforcement.

                  A. Reasonableness of Restrictions. Employee's compliance with
this Agreement is reasonable and necessary to protect Employer's legitimate
business interests, including but not limited to Employer's goodwill.

                  B. Irreparable Harm. A breach of Employee's obligations under
this Agreement will result in great, irreparable and continuing harm and damage
to Employer for which there is no adequate remedy at law.

<PAGE>

                  C. Injunctive Relief. In the event Employee breaches this
Agreement, Employer shall be entitled to seek, from any court of competent
jurisdiction, preliminary and permanent injunctive relief to enforce the terms
of this Agreement, in addition to any and all monetary damages allowed by law,
against Employee.

                  D. Extension of Covenants. In the event Employee violates any
one or more of the covenants contained in Section 6 of this Agreement, Employee
agrees that the running of the term of each covenant so violated shall be tolled
during the period(s) of any such violation and the pendency of any litigation
arising out of any such violation.

                  E. Judicial Modification. The parties have attempted to limit
the Employee's right to compete only to the extent necessary to protect Employer
from unfair business practices and/or unfair competition. The parties recognize,
however, that reasonable people may differ in making such a determination.
Consequently, the parties hereby agree that, if the scope or enforceability of
the restrictive covenant is in any way disputed at any time, a court or other
trier of fact may modify and enforce the covenant to the extent that it believes
to be reasonable under the circumstances existing at that time.

                  F. Attorney Fees. In the event it becomes necessary for either
party to this Agreement to institute a suit at law or in equity for the purposes
of enforcing any of the provisions of this Agreement, the prevailing party shall
be entitled to recover said party's reasonable attorney's fees, plus court costs
and expenses, from the nonprevailing party.

                  Withholding from Final Paycheck. Employee expressly authorizes
Employer to withhold and deduct from Employee's final wages any amounts owed by
Employee to Employer at the time of the termination of employment, including but
not limited to, any draw deficiencies, reimbursement for unearned commissions,
and the value of unreturned or damaged Employer property. Employee further
expressly agrees to repay to Employer any additional sums owed by Employee to
Employer (above that which may be withheld) immediately upon termination of
Employee's employment. If the Company owes the Employee amounts exceeding those
that the Employee may owe the Company as outlined above, the Company agrees to
pay this amount at the time of the final paycheck. This amount would include all
monetary and stock compensation that may have been accrued but not paid by the
Company to Employee.

            8. Indemnity. Employee warrants and represents that Employee has not
violated, is not violating, and will not violate any of the terms or conditions
of any prior employment agreement, noncompetition or other restrictive covenant,
or other agreement entered into by Employee while in the employment of any other
employer; that Employee has not given and will not give to Employer at any time
any customer list, trade secret, or any other item of confidential information,
obtained or received while in the employment of any other employer; that
Employee's employment with Employer is not restricted or limited in any way by
any such employment agreement or restrictive covenant or by operation of any
state, federal or local regulation, statute or other law of any kind, name or
nature, including but not limited to trade secret laws and immigration laws; and
that Employee is in all respects duly qualified and eligible to work for
Employer. In the event any legal or administrative action is commenced against
the Employee, Employer or both, arising out of Employee's former employment by
another employer or Employee's illegal action or violation of one or more of the
warranties or representations set forth in this section, Employee agrees to
indemnify Employer for all damages, costs and expenses, including reasonable
attorney fees, which Employer may incur and/or be required to pay in connection
with such legal or administrative action. In the event any legal or
administrative action is commenced against the Company, the Employee or both,
arising out of any matter involving the Company, Company agrees to indemnify
Employee for all damages, costs and expenses, including

<PAGE>

reasonable attorney fees, which Employee may incur and/or be required to pay in
connection with such legal or administrative action, so long as such action does
not arise pursuant to the conduct of the Employee.

            9. Miscellaneous.

                  A. Survival. This Agreement shall be effective as of the date
first written above and that the terms of this Agreement shall remain in full
force and effect not only during the continuation of Employee's employment, but
also after the termination of employment for any reason by Employer or Employee.

                  B. Waiver. Failure of the Employer to exercise or otherwise
act with respect to any of its rights under this Agreement shall not be
construed as a waiver of any breach, nor prevent the Employer or Employee from
thereafter enforcing strict compliance with any and all terms of this Agreement.

                  C. Severability. If any part of this Agreement shall be
adjudicated to be invalid or unenforceable, as to duration, territory or
otherwise, then such part shall be deemed deleted from this Agreement or
amended, as the case may be, in order to render the remainder of this Agreement
valid and enforceable.

                  D. Agreement Binding. This Agreement shall be binding upon and
inure to the benefit of Employer, Employer's successors and assigns, Employee
and Employee's heirs, executors, administrators and legal representatives.

                  E. Governing Law. This Agreement is made and entered into in
the State of Texas, where Employer has its principal place of business, and
concerns employment situated in said state. This Agreement shall be interpreted
and construed in accordance with the laws of the State of Texas.

                  F. Titles and Captions. All section and paragraph titles and
captions contained in this Agreement are for convenience only and shall not be
deemed part of the context nor affect the construction or interpretation of this
Agreement.

                  G. Entire Agreement. This Agreement contains all the
understandings and agreements between the parties concerning matters set forth
in this Agreement. The terms of this Agreement supersede any and all prior
statement, representations and agreements by or between Employer and Employee,
or either of them, concerning the matters set forth in this Agreement. Employee
acknowledges that no person who is an agent or employee of Employer may orally
or by conduct modify, delete, vary, or contradict the terms or conditions of
this Agreement or this paragraph. This Agreement may be modified only by a
written agreement signed by both parties.

                  Employee acknowledges that Employee has read and understands
the entire contents of this Agreement and that Employee has received a copy of
this Agreement.

such places or in such areas or territories as required for Company's operation,
provided however, that if Company relocates Chief Executive Officer from
Houston, Texas without the concurrence of Chief Executive Officer, such action
by Company shall, at the option of Chief Executive Officer constitute a

      4. Engagement.

            A. Term of Engagement. Chief Executive Officer's term of engagement
under this Agreement shall commence on August 22, 2000 and shall continue until
(a) terminated by Company, for "Cause" (as defined below), or (b) Company and
Chief Executive Officer mutually agree to the termination or extension of Chief
Executive Officer's engagement, in writing signed by both of them in accordance
with Section 9(G) of this Agreement (c) there occurs one of the four following
events the occurrence of which shall be considered a termination without cause:
1) a merger in which the Company is not the surviving entity, 2) a sale of
substantially all of the assets of Company, 3) a transaction or series of
transactions pursuant to which the Company adopts a plan of dissolution or
liquidation, or 4) any other organization, consolidation or transaction in which
current owners no longer maintain either voting control or the ability to elect
a majority of the directors of the Company (post MiraQuest transaction), (d)
Chief Executive Officer provides Company ninety (90) days notice of his
intention to terminate his engagement with Company, or (e) Chief Executive
Officer becomes disabled thus impairing his ability to perform his duties, which
condition shall be treated as a termination without cause and the pay and
benefits associated with termination without cause shall apply. In the event of
Chief Executive Officer's giving notice of intent to resign, the Company has the
choice of releasing Chief Executive Officer of his duties and obligations and
continuing his compensation and benefits for the ninety (90) day period or
requiring Chief Executive Officer to continue his duties and meeting his
obligations as an Chief Executive Officer until the expiration of the ninety
(90) day period.

            B. Termination of Engagement. During the term of this Agreement, the
Company may terminate the engagement of the Chief Executive Officer for "Cause"
by giving the Chief Executive Officer written notice of such termination setting
forth the "Cause" relied upon. For the purposes of this Agreement, "Cause" shall
include but not be limited to (i) the Chief Executive Officer's disregard of
lawful instructions of the Company that are consistent with the Chief Executive
Officer's position and duties set forth herein; (ii) the Chief Executive
Officer's failure to perform Chief Executive Officer's duties in compliance with
Company's reasonable standards of performance and not as a result of notice of
intention to resign, disability or retirement; (iii) the Chief Executive
Officer's willful actions which do or are likely to result unjustifiably in
material damage or embarrassment to the Company, the Company's reputation, or
the Company's other legitimate business interests ; (iv) the Chief Executive
Officer's abuse or illegal use of alcohol or other drugs or controlled
substances; (v) the Chief Executive Officer's material breach of any of the
terms or conditions of this Agreement; (vi) the conviction of the Chief
Executive Officer of a felony or entry of a guilty plea or plea of nolo
contendere by Chief Executive Officer to a felony (or any other crime that has
or might have a material adverse effect upon Chief Executive Officer's ability
to carry out Chief Executive Officer's job duties or other obligations under
this Agreement); or (vii) the Chief Executive Officer's theft, embezzlement or
misappropriation of funds from the Company. In the event Company wishes to
terminate Chief Executive Officer's engagement pursuant to Subsection (i), (ii),
(iii), (iv), or (v) above, Company shall give to Chief Executive Officer thirty
(30) days' notice of Company's intention to terminate Chief Executive Officer's
engagement and the reason(s) for such termination. If Chief Executive Officer
wishes to remain engaged by Company, Chief Executive Officer shall during such
thirty (30) day period remedy to the reasonable satisfaction of Company's Board
of Directors the misconduct, disregard, abuse, or other breach specified in such
notice. If Chief Executive

<PAGE>

Officer does not so remedy such breach to the reasonable satisfaction of
Company's Board of Directors, then the termination shall take effect at the end
of the thirty (30) day period. A termination pursuant to Subsection (vi) or
(vii) shall take effect immediately upon the giving of notice. Achievement of
desired results or performance established as a goal by the Company shall not be
a basis of termination for Cause. Any benefits or compensation to be earned
based on performance criteria will terminate with Chief Executive Officer's
termination whether with or without cause.

            C. Termination Without Cause. Company may terminate the Chief
Executive Officer's engagement without Cause at any time within the Chief
Executive Officer's first 120 days of engagement upon payment to Chief Executive
Officer of severance compensation equivalent to compensation for 2 10 days of
engagement reduced by the compensation paid to Chief Executive Officer through
the date of termination. After Chief Executive Officer has been employed and
paid for the excess of 120 days, Company may terminate the engagement of the
Chief Executive Officer without Cause upon payment to Chief Executive Officer of
severance compensation equivalent to compensation for six (6) months, including
all benefits. Equity compensation is not included as component of the
termination without cause severance compensation calculation.

            D. Equal Opportunity Company. Company is an Equal Employment
Opportunity organization and shall not discriminate against Chief Executive
Officer on the basis of age, color, creed, disability, marital status, national
origin, political ideology, race, religion, sex, sexual orientation, or status
as a disabled veteran or veteran of the Vietnam war era, with respect to
promotion, transfer, compensation, benefits or any other employment decision.

            E. Work Environment. In addition, Company is committed to
maintaining a positive, constructive working environment and will not tolerate
harassment or abuse of Chief Executive Officer in the workplace. If Chief
Executive Officer feels Chief Executive Officer has been subjected to
discrimination, harassment or abuse in connection with Chief Executive Officer's
engagement, Company encourages Chief Executive Officer to bring any and all such
matters to the attention of Company's chief human resources officer and/or Board
of Directors, who will conduct an investigation of all such matters brought to
their attention and take such personnel action as is appropriate under the
circumstances. Chief Executive Officer will not be subjected to retaliation for
submitting complaints to Company's chief human resources officer and/or Board of
Directors.

      5. Confidential Information.

            A. Definition of Confidential Information. Company is in the

Information through inventions, discoveries, improvements, software development,
and/or in other ways.

            B. Chief Executive Officer Access to Confidential Information. Chief
Executive Officer shall: (a) access only such Confidential Information as is
reasonably necessary to perform Chief Executive Officer's job functions; and (b)
allow access to Confidential Information under Chief Executive Officer's control
to only those employees whose job functions for Company reasonably necessitate

            C. Nondisclosure of Confidential Information. Chief Executive

directly or indirectly, appropriate, disclose or divulge any Confidential
Information to any person not then employed by Company, unless authorized or
directed to do so by Company or required to do so by a court or other
governmental entity acting with the force of law. If Company authorizes or
directs Chief Executive Officer to disclose Confidential Information to any
third party, Chief Executive Officer must ensure that a signed confidentiality
agreement for the benefit of Company is or has been obtained from the third
party to whom Confidential Information is being disclosed and that all
Confidential Information so disclosed is clearly marked "Confidential."

            D. Return of Confidential and Other Information. All Confidential
Information provided to Chief Executive Officer, and all documents and things
prepared by Chief Executive Officer in the conduct of his duties for Company,

term is defined in the copyright laws of the United States. Chief Executive
Officer shall cooperate with Company or its designees and execute assignments,
oaths, declarations, and other documents prepared by Company, to effect the
terms, of this Section 5(E) or to perfect or enforce any proprietary rights
resulting from or related to this Agreement. Such cooperation and execution
shall be at no additional compensation to Chief Executive Officer; provided,
however, Company shall reimburse Chief Executive Officer for reasonable
out-of-pocket expenses incurred at the specific request of Company. Company in
turn recognizes that Chief Executive Officer is engaged in other companies and
with other, separate responsibilities, and that, in the course of such separate
engagement he may develop or extend confidential information applicable to such
companies that is not part of his duties within this contract and to which
Company has no right, title or interest. Such recognition shall not be construed
to alter the duties of Chief Executive Officer as set forth in Section 2 of this
agreement.

      6. NonCompetition Obligations. During the term of Chief Executive
Officer's engagement with Company, and for a 12 month period of time following
termination of such engagement for any reason, Chief Executive Officer will not,
directly or indirectly, at any place in the United States, either for
him/herself or on behalf of any other person, partnership, corporation or other
entity

            (a)   solicit, divert, take away, or attempt to solicit, divert or
                  take away, any of Company's customers or the business or
                  patronage of any such customer;

            (b)   solicit, recruit or hire any other Employee of Company; or

            (c)   otherwise engage or become interested (as owner, stockholder,
                  partner, director, officer, member, creditor, consultant, or
                  employee) in any chronic disease management / monitoring
                  business, including pharmaceutical and medical supply delivery
                  to patients, in competition with any portion of the chronic
                  disease management/monitoring business conducted by Company at
                  any time during Chief Executive Officer's engagement with
                  Company unless such activity is set forth in Exhibit B as an
                  activity in which Chief Executive Officer is engaged on the
                  Effective Date of this Agreement is initiated.

Chief Executive Officer acknowledges that Company is doing business throughout
the United States, that Chief Executive Officer is reasonably expected to have
contact with Company's customers throughout the United States during the term of
Chief Executive Officer's engagement with Company, and that the national
geographic scope of these covenants is reasonably necessary to protect Company's
legitimate business interests.

      7. Enforcement.

            A. Reasonableness of Restrictions. Chief Executive Officer's
compliance with this Agreement is reasonable and necessary to protect Company's
legitimate business interests, including but not limited to Company's goodwill.

EMPLOYMENT, CONFIDENTIALITY & NONCOMPETITION AGREEMENT - 5

060200                                                                      1050
<PAGE>

            B. Irreparable Harm. A breach of Chief Executive Officer's
obligations under this Agreement will result in great, irreparable and
continuing harm and damage to Company for which there is no adequate remedy at
law.

            C. Injunctive Relief. In the event Chief Executive Officer breaches
this Agreement, Company shall be entitled to seek, from any court of competent
jurisdiction, preliminary and permanent injunctive relief to enforce the terms
of this Agreement, in addition to any and all monetary damages allowed by law,
against Chief Executive Officer.

            D. Extension of Covenants. In the event Chief Executive Officer
violates any one or more of the covenants contained in Section 6 of this
Agreement, Chief Executive Officer agrees that the running of the term of each
covenant so violated shall be tolled during the period(s) of any such violation
and the pendency of any litigation arising out of any such violation.

            E. Judicial Modification. The parties have attempted to limit the
Chief Executive Officer's right to compete only to the extent necessary to
protect Company from unfair business practices and/or unfair competition. The
parties recognize, however, that reasonable people may differ in making such a
determination. Consequently, the parties hereby agree that, if the scope or
enforceability of the restrictive covenant is in any way disputed at any time, a
court or other trier of fact may modify and enforce the covenant to the extent
that it believes to be reasonable under the circumstances existing at that time.

            F. Attorney Fees. In the event it becomes necessary for either party
to this Agreement to institute a suit at law or in equity for the purposes of
enforcing any of the provisions of this Agreement, the prevailing party shall be
entitled to recover said party's reasonable attorney's fees, plus court costs
and expenses, from the nonprevailing party.

            G. Withholding from Final Paycheck. Chief Executive Officer
expressly authorizes Company to withhold and deduct from Chief Executive
Officer's final wages any amounts owed by Chief Executive Officer to Company at
the time of the termination of engagement, including but not limited to, any
draw deficiencies, reimbursement for unearned commissions, and the value of
unreturned or damaged Company property. Chief Executive Officer further
expressly agrees to repay to Company any additional sums owed by Chief Executive
Officer to Company (above that which may be withheld) immediately upon
termination of Chief Executive Officer's engagement. If the Company owes the
Chief Executive Officer amounts exceeding those that the Chief Executive Officer
may owe the Company as outlined above, the Company agrees to pay this amount at
the time of the final paycheck. This amount would include all monetary and stock
compensation that may have been accrued but not paid by the Company to Robert B.
Teague, whether acting in the role of Chief Executive Officer or prior roles of
Medical Director and Chief Medical Officer.

            Indemnity. Chief Executive Officer warrants and represents that
Chief Executive Officer has not violated, is not violating, and will not violate
any of the terms or conditions of any prior employment agreement, noncompetition
or other restrictive covenant, or other agreement entered into by Chief
Executive Officer while in the employment of any other company; that Chief
Executive Officer has not given and will not give to Company at any time

any customer list, trade secret, or any other item of confidential information,
obtained or received while in the employment of any other Company; that Chief
Executive Officer's engagement with Company is not restricted or limited in any
way by any such engagement agreement or restrictive covenant or by operation of
any state, federal or local regulation, statute or other law of any kind, name
or nature, including but not limited to trade secret laws and immigration laws;
and that Chief Executive Officer is in all respects duly qualified and eligible
to work for Company. In the event any legal or administrative action is
commenced against the Chief Executive Officer, Company or both, arising out of
Chief Executive Officer's former employment by another Company or Chief
Executive Officer's illegal action or violation of one or more of the warranties
or representations set forth in this section, Chief Executive Officer agrees to
indemnify Company for all damages, costs and expenses, including reasonable
attorney fees, which Company may incur and/or be required to pay in connection
with such legal or administrative action. Company warrants and represents that
Company has not violated, is not violating, and will not violate any of the
terms or conditions of any prior employment agreement, noncompetition or other
restrictive covenant, or other agreement entered into by Company; that Company's
hiring of Chief Executive Officer is not restricted or limited in any way by any
agreement or restrictive covenant or by operation of any state, federal or local
regulation, statute or other laws. In the event any legal or administrative
action is commenced against the Company, the Chief Executive Officer or both,
arising out of any matter involving the Company, Company agrees to indemnify
Chief Executive Officer for all damages, costs and expenses, including
reasonable attorney fees, which Chief Executive Officer may incur and/or be
required to pay in connection with such legal or administrative action, so long
as such action does not arise pursuant to the conduct of the Chief Executive
Officer.

      9. Miscellaneous.

            A. Survival. This Agreement shall be effective as of the date first
written above and that the terms of this Agreement shall remain in full force
and effect not only during the continuation of Chief Executive Officer's
engagement, but also after the termination of engagement for any reason by
Company or Chief Executive Officer.

            B. Waiver. Failure of the Company to exercise or otherwise act with
respect to any of its rights under this Agreement shall not be construed as a
waiver of any breach, nor prevent the Company or Chief Executive Officer from
thereafter enforcing strict compliance with any and all terms of this Agreement.

            C. Severability. If any part of this Agreement shall be adjudicated
to be invalid or unenforceable, as to duration, territory or otherwise, then
such part shall be deemed deleted from this Agreement or amended, as the case
may be, in order to render the remainder of this Agreement valid and
enforceable.

            D. Agreement Binding. This Agreement shall be binding upon and inure
to the benefit of Company, Company's successors and assigns, Chief Executive
Officer and Chief Executive Officer's heirs, executors, administrators and legal
representatives.

the case of a special meeting, the purpose or purposes for which the meeting is
called.

     2.5  Advance Notice of Nominees.
          --------------------------

          Only persons who are nominated in accordance with the procedures set
forth in this Section 2.5 shall be eligible for election as directors.
Nominations of persons for election to the Board of Directors of the corporation
may be made at a meeting of stockholders by or at the direction of the Board of
Directors or by any stockholder of the corporation entitled to vote for the
election of directors at the meeting who complies with the notice procedures set
forth in this Section 2.5. Such nominations, other than those made by or at the
direction of the Board of Directors, shall be made pursuant to timely notice in
writing to the secretary of the corporation.

          To be timely, a stockholder's notice shall be delivered to or mailed
and received at the principal executive offices of the corporation (a) in the
case of an annual meeting, not less than sixty (60) days nor more than ninety
(90) days prior to the first anniversary of the preceding year's annual meeting;
provided, however, that in the event that the date of the annual meeting is
changed by more than thirty (30) days from such anniversary date, notice by the
stockholder to be timely must be so received not later than the close of
business on the tenth (10th) day following the earlier of the day on which such
notice of the date of the meeting was mailed or such public disclosure was made;
and (b) in the case of a special meeting at which Directors are to be elected,
not later than the close of business on the tenth (10th) day following the
earlier of the day on which notice of the date of the meeting was mailed or
public disclosure was made. Such stockholder's notice shall set forth (a) as to
each person whom the stockholder proposes to nominate for election or re-
election as a Director (i) the name, age, business address and residence address
of such person, (ii) the principal occupation or employment of such person,
(iii) the class and number of shares of the corporation which are beneficially

                                      -2-
<PAGE>

person and (iv) any other information relating to such person that is required
to be disclosed in solicitations of proxies for election of Directors, or is
otherwise required, in each case pursuant to Regulation 14A under the Securities
Exchange Act of 1934, as amended (including, without limitation, such person's
written consent to being named in the proxy statement as a nominee and to
serving as a director if elected); and (b) as to the stockholder giving the
notice (i) the name and address, as they appear on the corporation's books, of
such stockholder, (ii) the class and number of shares of the corporation which
are beneficially owned by such stockholder and also which are owned of record by
such stockholder and (iii) a description of all arrangements or understandings
between such stockholder and each nominee and any other person or persons
(naming such person or persons) relating to the nomination. At the request of
the Board of Directors any person nominated by the Board of Directors for
election as a director shall furnish to the secretary of the corporation that
information required to be set forth in a stockholder's notice of nomination
which pertains to the nominee.

          No person shall be eligible for election as a director of the
corporation unless nominated in accordance with the procedures set forth in this
Section 2.5. The Chairman of the meeting shall, if the facts warrant, determine
and declare to the meeting that a nomination was not made in accordance with the
procedures prescribed by the Restated Bylaws, and if he or she should so
determine, he or she shall so declare to the meeting and the defective
nomination shall be disregarded. Notwithstanding the foregoing provisions of
this Bylaw, a stockholder shall also comply with all applicable requirements of
the Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder with respect to the matters set forth in this Bylaw.

     2.6  Advance Notice Of Stockholder Business.
          --------------------------------------

          At an annual meeting of the stockholders, only such business shall be
conducted as shall have been properly brought before the annual meeting. To be
properly brought before an annual meeting, business must be: (a) pursuant to the
corporation's notice of meeting (or any supplement thereto), (b) by or at the
direction of the Board of Directors, or (c) by any stockholder of the
corporation who is a stockholder of record at the time of giving of the notice
provided for in this Section 2.6, who shall be entitled to vote at such meeting
and who complies with the notice procedures set forth in this Section 2.6.
Business to be brought before an annual meeting by a stockholder shall not be
considered properly brought if the stockholder has not given timely notice
thereof in writing to the secretary of the corporation.

          To be timely, a stockholder's notice must be delivered to or mailed
and received at the principal executive offices of the corporation not less than
sixty (60) nor more than ninety (90) days prior to the first anniversary of the
preceding year's annual meeting; provided, however, that in the event that the
date of the meeting is changed by more than thirty (30) days from such
anniversary date, notice by the stockholder to be timely must be so received not
later than the close of business on the tenth (10th) day following the earlier
of the day on which such notice of the date of the meeting was mailed or such
public disclosure was made. A stockholder's notice to the secretary shall set
forth as to each matter the stockholder proposes to bring before the meeting:
(i) a brief description of the business desired to be brought before the meeting
and the reasons for conducting such business at the meeting, (ii) the name and
address,

                                      -3-
<PAGE>

as they appear on the corporation's books, of the stockholder proposing such
business, and the name and address of the beneficial owner, if any, on whose
behalf the proposal is made, (iii) the class and number of shares of the
corporation, which are owned by the stockholder of record and by the beneficial
owner, if any, on whose behalf the proposal is made, (iv) any material interest
of the stockholder of record and the beneficial owner, if any, on whose behalf
the proposal is made in such business, and (v) any other information that is
required by law to be provided by the stockholder in his or her capacity as a
proponent of a stockholder proposal.

     Notwithstanding anything in these Restated Bylaws to the contrary, no
business shall be conducted at an annual meeting except in accordance with the
procedures set forth in this Section 2.6. The chairman of the meeting shall, if
the facts warrant, determine and declare at the meeting that business was not
properly brought before the meeting in accordance with the provisions of this
Section, and, if he or she should so determine, he or she shall so declare at
the meeting that any such business not properly brought before the meeting shall
not be transacted. Notwithstanding the foregoing provisions of this Bylaw, a
stockholder shall also comply with all applicable requirements of the Securities
Exchange Act of 1934, as amended, and the rules and regulations thereunder with
respect to the matters set forth in this Bylaw.

     2.7  Manner Of Giving Notice; Affidavit Of Notice.
          --------------------------------------------

          Written notice of any meeting of stockholders, if mailed, is given
when deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation.
Without limiting the manner by which notice otherwise may be given effectively
to stockholders, any notice to stockholders may be given by electronic mail or
other electronic transmission, in the manner provided in Section 232 of the
Delaware General Corporation Law. An affidavit of the secretary or an assistant
secretary or of the transfer agent of the corporation that the notice has been
given shall, in the absence of fraud, be prima facie evidence of the facts
stated therein.

     2.8  Quorum.
          ------

          The holders of a majority of the stock issued and outstanding and
entitled to vote thereat, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute or by the certificate of
incorporation. If, however, such quorum is not present or represented at any
meeting of the stockholders, then either (a) the chairman of the meeting or (b)
the stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum is present or
represented. At such adjourned meeting at which a quorum is present or
represented, any business may be transacted that might have been transacted at
the meeting as originally noticed.

     2.9  Adjourned Meeting; Notice.
          -------------------------

          When a meeting is adjourned to another time or place, unless these
Restated Bylaws otherwise require, notice need not be given of the adjourned
meeting if the time and

                                      -4-
<PAGE>

place, if any, thereof and the means of remote communications, if any, by which
stockholders and proxyholders may be deemed to be present and vote at such
adjourned meeting, are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the corporation may transact any business that
might have been transacted at the original meeting. If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting, specifying
the place, if any, date and time of the adjourned meeting and the means of
remote communications, if any, by which stockholders and proxyholders may be
deemed to be present and vote at such adjourned meeting.

     2.10  Conduct Of Business.
           -------------------

the conduct of business.

     2.11  Voting.
           ------

           (a) The stockholders entitled to vote at any meeting of stockholders
shall be determined in accordance with the provisions of Section 2.14 of these

incorporation, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder.

           (c) The Corporation may, and to the extent required by law, shall, in
advance of any meeting of stockholders, appoint one or more inspectors to act at

one or more inspectors to act at the meeting. Each inspector, before entering

     2.12  Waiver Of Notice.
           ----------------

           Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these Restated Bylaws, a written waiver thereof, signed by the person entitled
to notice, or waiver by electronic mail or other electronic transmission by such
person, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the stockholders need be specified in any written
waiver of notice unless so required by the certificate of incorporation or these
Restated Bylaws.

     2.13  Stockholder Action By Written Consent Without A Meeting.
           -------------------------------------------------------

     No action shall be taken by the stockholders of the corporation except at
an annual or special meeting of the stockholders called in accordance with the
Restated Bylaws and no action shall be taken by the stockholders by written
consent.

     2.14  Record Date For Stockholder Notice; Voting; Giving Consents.

           In order that the corporation may determine the stockholders entitled
to notice of or to vote at any meeting of stockholders or any adjournment
thereof, or entitled to express consent to corporate action in writing without a
meeting, or entitled to receive payment of any dividend or other distribution or
allotment of any rights, or entitled to exercise any rights in respect of any
change, conversion or exchange of stock or for the purpose of any other lawful
action, the Board of Directors may fix, in advance, a record date, which shall
not be more than sixty (60) nor less than ten (10) days before the date of such
meeting, nor more than sixty (60) days prior to any other action.

           If the Board of Directors does not so fix a record date:

           (a) The record date for determining stockholders entitled to notice
of or to vote at a meeting of stockholders shall be at the close of business on
the day next preceding the day on which notice is given, or, if notice is
waived, at the close of business on the day next preceding the day on which the
meeting is held.

           (b) The record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto.

           A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting
if such adjournment is for thirty (30) days or less; provided, however, that the
Board of Directors may fix a new record date for the adjourned meeting.

                                      -6-

     2.15  Proxies.
           -------

           Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to corporate action in writing without a meeting may
authorize another person or persons to act for such stockholder by an instrument
in writing or by an electronic transmission permitted by law filed with the
secretary of the corporation, but no such proxy shall be voted or acted upon
after three (3) years from its date, unless the proxy provides for a longer
period. A proxy shall be deemed signed if the stockholder's name is placed on
the proxy (whether by manual signature, typewriting, telegraphic transmission or
otherwise) by the stockholder or the stockholder's attorney-in-fact. The
revocability of a proxy that states on its face that it is irrevocable shall be
governed by the provisions of Section 212(e) of the General Corporation Law of
Delaware.

                                  ARTICLE III

                                   DIRECTORS
                                   ---------

     3.1  Powers.
          ------

          Subject to the provisions of the General Corporation Law of Delaware
and any limitations in the certificate of incorporation or these Restated Bylaws
relating to action required to be approved by the stockholders or by the
outstanding shares, the business and affairs of the corporation shall be managed
and all corporate powers shall be exercised by or under the direction of the
Board of Directors.

     3.2  Number Of Directors.
          -------------------

          Upon the adoption of these Restated Bylaws, the number of directors
constituting the entire Board of Directors shall be eight (8). Thereafter, this
number may be changed by a resolution of the Board of Directors or of the
stockholders, subject to Section 3.3 of these Restated Bylaws. No reduction of
the authorized number of directors shall have the effect of removing any
director before such director's term of office expires.

     3.3  Election, Qualification And Term Of Office Of Directors.
          -------------------------------------------------------

          (a) The Board of Directors of the corporation shall divide the
directors into two classes, as nearly equal in number as possible. The term of
office of the first class shall expire at the 1999 annual meeting of
stockholders or any special meeting in lieu thereof (or the next consecutive
annual meeting of stockholders when the corporation is Exempt from Section 2115
of the California Corporations Code), and the term of office of the second class
shall expire at the 2000 annual meeting of stockholders or any special meeting
in lieu thereof (or the next consecutive annual meeting of stockholders when the
corporation is Exempt from Section 2115 of the California Corporations Code). At
each annual meeting of stockholders or special meeting in lieu thereof following
such initial classification, directors elected to succeed those directors whose
terms expire shall be elected for a term of office to expire at the second
succeeding annual meeting of stockholders or special meeting in lieu thereof
after their election and until their

                                      -7-
<PAGE>

successors are duly elected and qualified. Directors need not be stockholders
unless so required by the certificate of incorporation or these Restated Bylaws,
wherein other qualifications for Directors may be prescribed.

          (b) Subject to the rights of the holders of any series of Preferred
Stock then outstanding, newly created directorships resulting from any increase
in the authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation, retirement, disqualification, removal from
office or other cause may be filled only by a majority vote of the directors
then in office even though less than a quorum, or by a sole remaining director.
In the event of any increase or decrease in the authorized number of directors,
(i) each director then serving as such shall nevertheless continue as a director
of the class of which he or she is a member until the expiration of his or her
current term or his or her prior death, retirement, removal or resignation and
(ii) the newly created or eliminated directorships resulting from such increase
or decrease shall if reasonably possible be apportioned by the Board of
Directors among the two classes of directors so as to ensure that no one class
has more than one director more than any other class.  To the extent reasonably
possible, consistent with the foregoing rule, any newly created directorships
shall be added to those classes whose terms of office are to expire at the
latest dates following such allocation and newly eliminated directorships shall
be subtracted from those classes whose terms of office are to expire at the
earliest dates following such allocation, unless otherwise provided for from
time to time by resolution adopted by a majority of the directors then in
office, although less than a quorum.  In the event of a vacancy in the Board of
Directors, the remaining directors, except as otherwise provided by law, may
exercise the powers of the full Board of Directors until the vacancy is filled.
Notwithstanding the foregoing, each director shall serve until his or her
successor is duly elected and qualified or until his or her death, resignation,
or removal.  No decrease in the number of directors constituting the Board of
Directors shall shorten the term of any incumbent director.

          (c) For the purposes of this Section 3.3, "Exempt from Section 2115 of
the California Corporation Code" as used in these Restated Bylaws shall mean
such time when the corporation has outstanding securities listed on the New York
Stock Exchange or the American Stock Exchange or outstanding securities
designated as qualified for trading as a national market security on the
National Association of Securities Dealers Automatic Quotation System (or such
successor national market system) with at least 800 holders of its equity
securities.  For the management of the business and for the conduct of the
affairs of the corporation, and in further definition, limitation and regulation
of the powers of the corporation, its directors and its stockholders or any
class thereof, as the case may be, it is further provided that, effective on the
record date of the first annual meeting of stockholders when the Company is
Exempt from Section 2115 of the California Corporations Code:

          (d) At the next consecutive annual or special meeting of stockholders
when the corporation is Exempt from Section 2115 of the California Corporations
Code, there shall be no right with respect to shares of stock of the corporation
to cumulate votes in the election of directors.

          (e) Election of Directors need not be by written ballot.

regular and special, either within or outside the State of Delaware.

          Unless otherwise restricted by the certificate of incorporation or
these Restated Bylaws, members of the Board of Directors, or any committee
designated by the Board of Directors, may participate in a meeting of the Board
of Directors, or any committee, by means of conference telephone or other
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

     3.5  Regular Meetings.
          ----------------

          Regular meetings of the Board of Directors may be held without notice
at such time and at such place as shall from time to time be determined by the
board.

     3.6  Special Meetings; Notice.
          ------------------------

          Special meetings of the Board of Directors for any purpose or purposes
may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two directors.

          Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation.  If the notice is mailed, it
shall be deposited in the United States mail at least four (4) days before the
time of the holding of the meeting.  If the notice is delivered personally, by
facsimile, by electronic transmission, by telephone or by telegram, it shall be
delivered at least forty-eight (48) hours before the time of the holding of the
meeting.  Any oral notice given personally or by telephone may be communicated
either to the director or to a person at the office of the director who the
person giving the notice has reason to believe will promptly communicate it to
the director.  The notice need not specify the purpose or the place of the
meeting, if the meeting is to be held at the principal executive office of the
corporation.

     3.7  Quorum.
          ------

          At all meetings of the Board of Directors, a majority of the
authorized number of directors shall constitute a quorum for the transaction of
business and the act of a majority of the directors present at any meeting at
which there is a quorum shall be the act of the Board of Directors, except as
may be otherwise specifically provided by statute or by the certificate of
incorporation.  If a quorum is not present at any meeting of the Board of
Directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.

                                      -9-
<PAGE>

           A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

     3.8   Waiver Of Notice.
           ----------------

           Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these Restated Bylaws, a written waiver thereof, signed by the person entitled
to notice, or waiver by electronic mail or other electronic transmission by such
person, whether before or after the time stated therein, shall be deemed
equivalent to notice.  Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened.  Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the directors, or members of a committee of
directors, need be specified in any written waiver of notice unless so required
by the certificate of incorporation or these Restated Bylaws.

     3.9   Board Action By Written Consent Without A Meeting.
           -------------------------------------------------

           Unless otherwise restricted by the certificate of incorporation or
these Restated Bylaws, any action required or permitted to be taken at any
meeting of the Board of Directors, or of any committee thereof, may be taken
without a meeting if all members of the board or committee, as the case may be,
consent thereto in writing or by electronic transmission and the writing or
writings or electronic transmission or transmissions are filed with the minutes
of proceedings of the board or committee.  Written consents representing actions
taken by the board or committee may be executed by telex, telecopy or other
facsimile transmission, and such facsimile shall be valid and binding to the
same extent as if it were an original.  Such filings shall be in paper form if
the minutes are maintained in paper form and shall be in electronic form if the
minutes are maintained in electronic form.

     3.10  Fees And Compensation Of Directors.
           ----------------------------------

           Unless otherwise restricted by the certificate of incorporation or
these Restated Bylaws, the Board of Directors shall have the authority to fix
the compensation of directors.  No such compensation shall preclude any director
from serving the corporation in any other capacity and receiving compensation
therefor.

     3.11  Approval Of Loans To Officers.
           -----------------------------

           The corporation may lend money to, or guarantee any obligation of, or
otherwise assist any officer or other employee of the corporation or of its
subsidiary, including any officer or employee who is a director of the
corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
corporation.  The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the Board of
Directors shall approve, including, without

                                      -10-

limitation, a pledge of shares of stock of the corporation. Nothing in this
section contained shall be deemed to deny, limit or restrict the powers of
guaranty or warranty of the corporation at common law or under any statute.

     3.12  Removal Of Directors.
           --------------------

           Unless otherwise restricted by statute, by the certificate of
incorporation or by these Restated Bylaws, any director or the entire Board of
Directors may be removed, with or without cause, by the holders of a majority of
the shares then entitled to vote at an election of directors; provided, however,
that if the stockholders of the corporation are entitled to cumulative voting,
if less than the entire Board of Directors is to be removed, no director may be
removed without cause if the votes cast against his removal would be sufficient
to elect him if then cumulatively voted at an election of the entire Board of
Directors.

           No reduction of the authorized number of directors shall have the
effect of removing any director prior to the expiration of such director's term
of office.

     3.13  Chairman Of The Board Of Directors.
           ----------------------------------

           The corporation may also have, at the discretion of the Board of

member or members present at any meeting and not disqualified from voting,

appoint another member of the Board of Directors to act at the meeting in the
place of any such absent or disqualified member.  Any such committee, to the
extent provided in the resolution of the Board of Directors, or in these
Restated Bylaws, shall have and may exercise all the powers and authority of the
Board of Directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
papers which may require it; but no such committee shall have the power or
authority in reference to the following matters:  (i) approving or adopting, or
recommending to the stockholders, any action or matter expressly required by the
General Corporate Law of Delaware to be submitted to stockholders for approval
or (ii) adopting, amending or repealing any Bylaw of the corporation.

changes in the context of such provisions as are necessary to substitute the
committee and its members for the Board of Directors and its members; provided,
however, that the time of regular meetings of committees may be determined
either by resolution of the Board of Directors or by resolution of the
committee, that special meetings of committees may also be called by resolution
of the Board of Directors and that notice of special meetings of committees
shall also be given to all alternate members, who shall have the right to attend
all meetings of the committee.  The Board of Directors may adopt rules for the
government of any committee not inconsistent with the provisions of these
Restated Bylaws.

permitted by the General Corporation Law of Delaware, indemnify each of its
directors and officers against expenses (including attorneys' fees), judgments,
fines, settlements and other amounts actually and reasonably incurred in
connection with any proceeding, arising by reason of the fact that such person

"director" or "officer" of the corporation includes any person (a) who is or was
a director or officer of the corporation, (b) who is or was serving at the
request of the corporation as a director or officer of another corporation,

corporation.

           -------------------------

           The corporation shall have the power, to the maximum extent and in
the manner permitted by the General Corporation Law of Delaware, to indemnify
each of its employees and agents (other than directors and officers) against
expenses (including attorneys' fees), judgments, fines, settlements and other
amounts actually and reasonably incurred in connection with any proceeding,
arising by reason of the fact that such person is or was an agent of the
corporation.

For purposes of this Section 6.2, an "employee" or "agent" of the corporation
(other than a director or officer) includes any person (a) who is or was an
employee or agent of the corporation, (b) who is or was serving at the request
of the corporation as an employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, or (c) who was an employee or agent of
a corporation which was a predecessor corporation of the corporation or of
another enterprise at the request of such predecessor corporation.

     6.3  Payment Of Expenses In Advance.
          ------------------------------

          Expenses incurred in defending any action or proceeding for which
indemnification is required pursuant to Section 6.1 or for which indemnification
is permitted pursuant to Section 6.2 following authorization thereof by the
Board of Directors shall be paid by the corporation in advance of the final
disposition of such action or proceeding upon receipt of an undertaking by or on
behalf of the indemnified party to repay such amount if it shall ultimately be
determined that the indemnified party is not entitled to be indemnified as
authorized in this Article VI.

     6.4  Indemnity Not Exclusive.
          -----------------------

          The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any bylaw, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in an official capacity and as to
action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the certificate of
incorporation.

     6.5  Insurance.
          ---------

          The corporation may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the corporation,
or is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred
by him or her in any such capacity, or arising out of his or her status as such,
whether or not the corporation would have the power to indemnify him or her
against such liability under the provisions of the General Corporation Law of
Delaware.

     6.6  Conflicts.
          ---------

          No indemnification or advance shall be made under this Article VI,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

          (a) That it would be inconsistent with a provision of the certificate
of incorporation, these Restated Bylaws, a resolution of the stockholders or an
agreement in effect at the time of the accrual of the alleged cause of the
action asserted in the proceeding in which the expenses were incurred or other
amounts were paid, which prohibits or otherwise limits indemnification; or

                                      -16-
<PAGE>

          (b) That it would be inconsistent with any condition expressly imposed
by a court in approving a settlement.

                                  ARTICLE VII

                              RECORDS AND REPORTS
                              -------------------

     7.1  Maintenance And Inspection Of Records.
          -------------------------------------

          The corporation shall, either at its principal executive offices or at
such place or places as designated by the Board of Directors, keep a record of
its stockholders listing their names and addresses and the number and class of
shares held by each stockholder, a copy of these Restated Bylaws as amended to
date, accounting books, and other records.

          Any stockholder of record, in person or by attorney or other agent,
shall, upon written demand under oath stating the purpose thereof, have the
right during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom.  A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder.  In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent to so act on
behalf of the stockholder.  The demand under oath shall be directed to the
corporation at its registered office in Delaware or at its principal place of
business.

          A complete list of stockholders entitled to vote at any meeting of
stockholders, arranged in alphabetical order for each class of stock and showing
the address of each such stockholder and the number of shares registered in each
such stockholder's name, shall be open to the examination of any such
stockholder for a period of at least ten (10) days prior to the meeting in the
manner provided by law.  The stock list shall also be open to the examination of
any stockholder during the whole time of the meeting as provided by law.  This
list shall presumptively determine the identity of the stockholders entitled to
vote at the meeting and the number of shares held by each of them.

     7.2  Inspection By Directors.
          -----------------------

          Any director shall have the right to examine the corporation's stock
ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his or her position as a director.  The Court of
Chancery is hereby vested with the exclusive jurisdiction to determine whether a
director is entitled to the inspection sought.  The Court may summarily order
the corporation to permit the director to inspect any and all books and records,
the stock ledger, and the stock list and to make copies or extracts therefrom.
The Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

                                 ARTICLE VIII

                                GENERAL MATTERS
                                ---------------

     8.1  Checks.
          ------

          From time to time, the Board of Directors shall determine by
resolution which person or persons may sign or endorse all checks, drafts, other
orders for payment of money, notes or other evidences of indebtedness that are
issued in the name of or payable to the corporation, and only the persons so
authorized shall sign or endorse those instruments.

     8.2  Execution Of Corporate Contracts And Instruments.
          ------------------------------------------------

          The Board of Directors, except as otherwise provided in these Restated
Bylaws, may authorize any officer or officers, or agent or agents, to enter into
any contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the Board of Directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

     8.3  Stock Certificates; Partly Paid Shares.
          --------------------------------------

          The shares of a corporation shall be represented by certificates,
provided that the Board of Directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares.  Any such resolution shall not apply
to shares represented by a certificate until such certificate is surrendered to
the corporation.  Notwithstanding the adoption of such a resolution by the Board
of Directors, every holder of stock represented by certificates and upon request
every holder of uncertificated shares shall be entitled to have a certificate
signed by, or in the name of the corporation by the chairman or vice-chairman of
the Board of Directors, or the president or vice-president, and by the chief
financial officer or an assistant treasurer, or the secretary or an assistant
secretary of such corporation representing the number of shares registered in
certificate form.  Any or all of the signatures on the certificate may be a
facsimile.  In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate has ceased to be
such officer, transfer agent or registrar before such certificate is issued, it
may be issued by the corporation with the same effect as if he or she were such
officer, transfer agent or registrar at the date of issue.

          The corporation may issue the whole or any part of its shares as
partly paid and subject to call for the remainder of the consideration to be
paid therefor.  Upon the face or back of each stock certificate issued to
represent any such partly paid shares, upon the books and records of the
corporation in the case of uncertificated partly paid shares, the total amount
of the consideration to be paid therefor and the amount paid thereon shall be
stated.  Upon the declaration of any dividend on fully paid shares, the
corporation shall declare a dividend upon

                                      -18-
<PAGE>

partly paid shares of the same class, but only upon the basis of the percentage
of the consideration actually paid thereon.

     8.4  Special Designation On Certificates.
          -----------------------------------

          If the corporation is authorized to issue more than one class of stock
or more than one series of any class, then the powers, the designations, the
preferences, and the relative, participating, optional or other special rights
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences, and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

     8.5  Lost Certificates.
          -----------------

          Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time.  The corporation
may issue a new certificate of stock or uncertificated shares in the place of
any certificate previously issued by it, alleged to have been lost, stolen or
destroyed, and the corporation may require the owner of the lost, stolen or
destroyed certificate, or the owner's legal representative, to give the
corporation a bond sufficient to indemnify it against any claim that may be made
against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate or uncertificated shares.

     8.6  Construction; Definitions.
          -------------------------

          Unless the context requires otherwise, the general provisions, rules
of construction, and definitions in the Delaware General Corporation Law shall
govern the construction of these Restated Bylaws.  Without limiting the
generality of this provision, the singular number includes the plural, the
plural number includes the singular, and the term "person" includes both a
corporation and a natural person.

     8.7  Dividends.
          ---------

          The directors of the corporation, subject to any restrictions
contained in (a) the General Corporation Law of Delaware or (b) the certificate
of incorporation, may declare and pay dividends upon the shares of its capital
stock.  Dividends may be paid in cash, in property, or in shares of the
corporation's capital stock.

                                      -19-
<PAGE>

           The directors of the corporation may set apart out of any of the
funds of the corporation available for dividends a reserve or reserves for any
proper purpose and may abolish any such reserve. Such purposes shall include but
not be limited to equalizing dividends, repairing or maintaining any property of
the corporation, and meeting contingencies.

     8.8   Fiscal Year.
           -----------

           The fiscal year of the corporation shall be fixed by resolution of
the Board of Directors and may be changed by the Board of Directors.

     8.9   Seal.
           ----

           The corporation may adopt a corporate seal, which may be altered at
pleasure, and may use the same by causing it or a facsimile thereof, to be
impressed or affixed or in any other manner reproduced.

     8.10  Transfer Of Stock.
           -----------------

           Upon surrender to the corporation or the transfer agent of the
corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignation or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate, and record the transaction in its books.

     8.11  Stock Transfer Agreements.
           -------------------------

           The corporation shall have power to enter into and perform any
agreement with any number of stockholders of any one or more classes of stock of
the corporation to restrict the transfer of shares of stock of the corporation
of any one or more classes owned by such stockholders in any manner not
prohibited by the General Corporation Law of Delaware.

     8.12  Registered Stockholders.
           -----------------------

           The corporation shall be entitled to recognize the exclusive right of
a person registered on its books as the owner of shares to receive dividends and
to vote as such owner, shall be entitled to hold liable for calls and
assessments the person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of another person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

     8.13  Facsimile Signature
           -------------------

           In addition to the provisions for use of facsimile signatures
elsewhere specifically authorized in these Bylaws, facsimile signatures of any
officer or officers of the Corporation may be used whenever and as authorized by
the Board of Directors or a committee thereof.

                                  ----------

          The Restated Bylaws of the corporation may be adopted, amended or
repealed by the stockholders entitled to vote; provided, however, that the
corporation may, in its certificate of incorporation, confer the power to adopt,
amend or repeal Bylaws upon the directors.  The fact that such power
has been so conferred upon the directors shall not divest the stockholders of
the power, nor limit their power to adopt, amend or repeal Bylaws.
