foreign corporation and is in good standing in every jurisdiction in which the
nature of its business or the location of its properties requires such

of any Allstate Material Contract or the ability of Allstate to bring lawsuits,
or a Material Adverse Effect upon the condition (financial or otherwise),
assets, liabilities, business or operations of Allstate.

          (c)  Each Seller and Allstate has the full right, power and authority
required to enter into, execute and deliver this Agreement and the Allstate

Documents have been duly and validly authorized, executed and delivered by the

binding obligations of the Sellers and/or Allstate executing the same,
enforceable in accordance with their respective terms, except as such
enforceability may be limited by (i) bankruptcy, insolvency, reorganization,
moratorium or similar Laws now or hereafter in effect relating to or limiting
creditors' rights generally, and (ii) general principles of equity (whether
considered in an action in equity or at law) which provide, among other things,
that the remedies of specific performance and injunctive and other forms of
equitable relief are subject to equitable defenses and to the discretion of the
court before which any proceedings therefor may be brought.

or sale of securities, buy or otherwise dispose of or acquire any shares of
capital stock or any debt security of the Company.

          (g)  Neither the execution and delivery of this Agreement, the

accurate description of each consent, approval, authorization, notice, filing,
exemption or other requirement which must be obtained from any governmental
body, court or Person or which must otherwise be satisfied by the Sellers or
Allstate in order that neither (i) the execution or delivery by any of the
Sellers or the Allstate of this Agreement or any of the Seller Documents or the
Allstate Documents nor (ii) the consummation of the transactions contemplated

                                  ----------
             COVENANTS AND AGREEMENTS OF THE PARTIES AFTER CLOSING
             -----------------------------------------------------

     11.1  Covenants Against Competition. The Sellers acknowledge that the
           -----------------------------
Company would not purchase the Allstate Shares but for the agreements and
covenants of the Sellers contained in this Section 11.1. Accordingly, except as
expressly contemplated by the Service Agreement, each Seller, severally,
covenants and agrees as follows:

          (a)  Covenant Not to Compete. Such Seller shall not at any time within
               -----------------------
the Restricted Period have any ownership interest (of record or beneficial) in,
or have any interest as an employee, salesman, consultant, officer or director
in, or otherwise aid or assist in any manner, any firm, corporation,
partnership, proprietorship or other business that engages in any geographic
area listed in Section 11.1(a) of the Allstate Disclosure Schedule in a business
which is similar to that in which Allstate is engaged in any such geographic
area as of the Closing, so long as Allstate or any successor in interest of
Allstate to the business and goodwill of Allstate remains engaged in such
business in any such geographic area or continues to solicit customers or
potential customers therein. Notwithstanding the foregoing, such Seller may own
stock in publicly-held businesses for investment purposes that compete with or
engage in a business similar to Allstate; provided however, that investments in
each such business shall not exceed 2% of the shares outstanding on a fully
diluted basis.

          (b)  Solicitation of Business. During the Restricted Period such
               ------------------------
Seller shall not solicit or assist any other Person to solicit any business
(other than for Allstate or any of its Affiliates) from any present or past
customer of Allstate's business; or request or advise any present or future
customer of Allstate or any of its Affiliates to withdraw, curtail or cancel its
business dealings with Allstate or any of its Affiliates; or commit any other
act or assist others to commit any other act which might injure the business of
Allstate or any of its Affiliates.

          (c)  Employees. During the Restricted Period, such Seller shall not
               ---------
directly or indirectly solicit or encourage any employee of Allstate's business
to leave the employ of Allstate or any of its Affiliates; provided, however,
that such Seller may hire any employee who has terminated his or her employment
with, or has been terminated by, Allstate or any of its Affiliates.

          (d)  Rights and Remedies Upon Breach. If any Seller breaches, or
               -------------------------------
threatens to commit a breach of, any of the provisions of the Restrictive
Covenants, Allstate and/or the Company shall have the right and remedy to have
the Restrictive Covenants specifically enforced by any court having equity
jurisdiction, all without the need to post a bond or any other security or to
prove any amount of actual damage or that money damages would not provide an
adequate remedy, it being acknowledged and agreed that any such breach or
threatened breach will cause irreparable injury to Allstate and that monetary
damages will not provide an adequate remedy to Allstate.

          (e)  Severability of Covenants/Blue Pencilling.  If any court
               -----------------------------------------
determines that any of the Restrictive Covenants, or any part thereof, is
invalid or unenforceable, the remainder of the Restrictive Covenants shall not
thereby be affected and shall be given full effect, without

                                      34
<PAGE>

regard to the invalid portions. If any court determines that any of the
Restrictive Covenants, or any part thereof, is invalid or unenforceable, the
remainder of the Restrictive Covenants shall not thereby be affected and shall
be given full effect, without regard to the invalid portions. If any court
determines that any of the Restrictive Covenants, or any part thereof, is
unenforceable because of its duration or the area covered thereby, such court
shall have the power to reduce the duration or area of that provision and, in
its reduced form, that provision shall then be enforceable and shall be
enforced. Such Seller hereby waives any and all right to attack the validity of
the Restrictive Covenants on the grounds of the breadth of their geographic
scope or the length of their term.

     11.2  Release. In consideration of the payments to the Seller at the
           -------
Closing, effective as of the Closing Date, the Sellers, jointly and severally,
release and discharge Allstate, and each of its shareholders, Affiliates,
officers, directors, employees, agents and attorneys, from any and all claims,
contentions, demands, causes of action at law or in equity, debts, liens,
agreements, notes, obligations or liabilities of any nature, character or
description whatsoever, whether known or unknown, which they or either of them
may now or hereafter have against any such Persons by reason of any matter,
event, thing or state of facts occurring, arising, done, omitted or suffered to
be done prior to the Closing Date.

     The Sellers hereby acknowledge and represent that they, and each of them,
have been advised by their attorney of record, and are familiar with, Section
1542 of the Civil Code of the State of California, which presently provides as
follows:

          "A general release does not extend to claims which the
          creditor does not know or suspect to exist in his favor at
          the time of executing the release, which if known by him
          must have materially affected his settlement with the
          debtor."

     The Sellers hereby waive and relinquish any and all rights and benefits
under Section 1542 of the Civil Code as now worded and as it may from time to
time hereafter be amended.

     It is understood by each Seller that the facts in respect of which this
release is given may hereafter turn out to be other than or different from the
facts in that connection known or believed by them to be true.  Each Seller
therefore expressly assumes the risk of the facts turning out to be so different
and agrees that the foregoing release shall be in all respects effective and not
subject to termination or rescission by any such difference in facts.

     11.3  Dispute Assistance. The Sellers agree that in the event of any
           ------------------
dispute with respect to the business or operations of Allstate arising out of
events which occurred prior to the Closing, they shall cooperate with the
Company, at no cost to the Company, in the resolution of such dispute,
including, without limitation, making appearances in the Los Angeles,
California, Houston, Texas, Phoenix, Arizona and Washington, D.C. areas (it
being understood that appearances outside such areas shall be at the expense of
the Company) in any litigation which may result therefrom; provided, however,
that this agreement by the Sellers to cooperate shall not be deemed an
acceptance by the Sellers of any liability arising from such dispute, as to
which the other provisions of this Agreement shall control.

     11.4 Removal of Guaranties.  The Company covenants and agrees that it will
          ---------------------
use its reasonable and diligent best efforts to cause all of the guarantors
under the Lease Agreement to be removed from the Lease Agreement. The Company
further covenants and agrees that it will, promptly after the Closing Date, pay
in full any and all obligations owed on the equipment or other assets or
property of Allstate, wherever located, that are covered by a guaranty by any
Seller or an affiliate of a Seller. In each case the Company agrees to
indemnify, defend and hold harmless Allstate, and each of the Sellers, from and
against any and all Losses which may be incurred or suffered by any such party
and which may arise out of or result from Allstate not fulfilling its
commitments under the Lease Agreement or such other obligations."

     11.5 Allocation Of Working Capital.  After Closing, the Company shall
          -----------------------------
allocate at least $1,150,000 of the cash required pursuant to Section 10.6, to
the operations of Allstate.

     11.6 Additional Private Placement.  The Company shall use reasonable
          ----------------------------
efforts to raise within three months of the Closing at least $1 million in gross
proceeds from a private placement of the Company's equity securities. In using
reasonable efforts, the Company shall take into account the terms of such
additional private placement and the potential dilution applicable to the
Company shareholders, including the Sellers.

                                  ARTICLE XII
                                  -----------
                                INDEMNIFICATION
                                ---------------

     12.1 Indemnification by the Sellers and Allstate.  The Sellers jointly and
          -------------------------------------------
severally and, prior to (but not after) the Closing, Allstate, jointly and
severally with the Sellers (except that each of Seller's obligations pursuant to
Article IV hereof shall be several), shall indemnify, defend and hold harmless
(i) the Company, (ii) each of the Company's assigns and successors in interest
to the Allstate Shares, (iii) after the Closing occurs, Allstate and each
successor in interest to the assets or business of Allstate and (iv) each of
their respective shareholders, members, partners, directors, officers, managers,
employees, agents, attorneys and representatives, from and against any and all
Losses which may be incurred or suffered by any such party and which may arise
out of or result from any breach of any representation, warranty, covenant or
agreement of the Sellers or Allstate contained in this Agreement or in any other
Allstate Document or Seller Document.  By way of clarification and without
duplication, to the extent such breach of representation, warranty, covenant or
agreement results in Losses to which Allstate would not have been subjected had
the state of facts been as represented or warranted or had the covenant or
agreement been performed, the Company as the direct or indirect owner of
Allstate shall also be deemed to have been damaged to the extent of such Losses.
Notwithstanding the foregoing, (a) the parties entitled to such indemnification
under this Article XII shall be entitled to such indemnification only to the
extent that the aggregate amount of such Losses exceed $100,000, and such
parties shall be indemnified only for such Losses in excess of $100,000, (b)
each Seller shall be liable for such Losses on a pro rata basis, that is in the
same proportion as the percentage of Company Shares received by such Seller at
the Closing, (c) the parties entitled to such indemnification under this Article
XII shall, if and to the extent available, seek recovery from insurance proceeds
prior to seeking recovery directly from a Seller, and (d) except as set forth in
the following sentence, the liability of each Seller shall be limited to the
amount that is equal to the number of Company Shares received by such Seller at
the Closing

                                      36
<PAGE>

multiplied by $0.75 (the "Assumed Value"). The limitation set forth in clause
(d) shall not apply to a Seller in the case of a misrepresentation made by such
Seller with actual knowledge of such misrepresentation. At each Seller's option,
his pro rata share of Losses for which he is liable may be satisfied by cash or
a tender of Company Shares. The value of the Company Shares tendered, if any,
shall be determined by the average of the reported Closing Prices of the Common
Stock of the Company for each of the ten trading days immediately preceding the
date the Loss was incurred except that the value of each Company Share shall be
deemed to be the Assumed Value during any period of time that the Company Shares
held by such Seller are "restricted securities" as defined pursuant to the
Securities Act of 1933, as amended.

     12.2 Indemnification by the Company.  The Company shall indemnify, defend
          ------------------------------
and hold harmless Allstate, and each of the Sellers from and against any and all
Losses which may be incurred or suffered by any such party and which may arise
out of or result from any breach of any representation, warranty, covenant or
agreement of the Company contained in this Agreement or in any other Company
Document.  Notwithstanding the foregoing, the parties entitled to such
indemnification under this Article XII shall be entitled to such indemnification
only to the extent that the aggregate amount of such Losses exceed $100,000, and
such parties shall be indemnified only for such Losses in excess of $100,000.

     12.3 Notice to Indemnifying Party.  If any party (the "Indemnified Party")
          ----------------------------
receives notice of any claim or other commencement of any action or proceeding
with respect to which any other party (or parties) (the "Indemnifying Party") is
obligated to provide indemnification pursuant to Sections 12.1 or 12.2 pursuant
to any other specific indemnification covenant contained in this Agreement, the
Indemnified Party shall promptly give the Indemnifying Party written notice
thereof, which notice shall specify in reasonable detail, if known, the amount
or an estimate of the amount of the liability arising therefrom and the basis of
the claim.  Such notice shall be a condition precedent to any liability of the
Indemnifying Party for indemnification hereunder, but the failure of the
Indemnified Party to give prompt notice of a claim shall not adversely affect
the Indemnified Party's right to indemnification hereunder unless the defense of
that claim is materially prejudiced by such failure.  The Indemnified Party
shall not settle or compromise any claim by a third party for which it is
entitled to indemnification hereunder without the prior written consent of the
Indemnifying Party (which shall not be unreasonably withheld or delayed) unless
suit shall have been instituted against it and the Indemnifying Party shall not
have taken control of such suit after notification thereof as provided in
Section 12.4.

     12.4 Defense by Indemnifying Party.  In connection with any claim giving
          -----------------------------
rise to indemnity hereunder resulting from or arising out of any claim or legal
proceeding by a Person who is not a party to this Agreement, the Indemnifying
Party at its sole cost and expense may, upon written notice to the Indemnified
Party, assume the defense of any such claim or legal proceeding (i) if it
acknowledges to the Indemnified Party in writing its obligations to indemnify
the Indemnified Party with respect to all elements of such claim (subject to any
limitations on such liability contained in this Agreement) and (ii) if it
provides assurances, reasonably satisfactory to the Indemnified Party, that it
will be financially able to satisfy such claims in full if the same are decided
adversely.  If the Indemnifying Party assumes the defense of any such claim or
legal proceeding, it may use counsel of its choice to prosecute such defense,
subject to the approval of such counsel by the Indemnified Party, which approval
shall not be unreasonably

                                      37
<PAGE>

withheld or delayed. In this regard, Loeb & Loeb LLP is hereby approved by the
Sellers as counsel to the Company (in its capacity as the Indemnifying Party),
and LeBoeuf, Lamb, Greene & MacRae LLP is hereby approved by the Company as
counsel to the Sellers (in their capacity as the Indemnifying Party). The
Indemnified Party shall be entitled to participate in (but not control) the
defense of any such action, with its counsel and at its own expense; provided,
however, that if the Indemnified Party, in its sole discretion, determines that
there exists a conflict of interest between the Indemnifying Party (or any
constituent party thereof) and the Indemnified Party, the Indemnified Party (or
any constituent party thereof) shall have the right to engage separate counsel,
the reasonable costs and expenses of which shall be paid by the Indemnified
Party. If the Indemnifying Party assumes the defense of any such claim or legal
proceeding, the Indemnifying Party shall take all steps necessary to pursue the
resolution thereof in a prompt and diligent manner. The Indemnifying Party shall
be entitled to consent to a settlement of, or the stipulation of any judgment
arising from, any such claim or legal proceeding, with the consent of the
Indemnified Party, which consent shall not be unreasonably withheld or delayed;
provided, however, that no such consent shall be required from the Indemnified
Party if (i) the Indemnifying Party pays or causes to be paid all Losses arising
out of such settlement or judgment concurrently with the effectiveness thereof
(as well as all other Losses theretofore incurred by the Indemnified Party which
then remain unpaid or unreimbursed), (ii) in the case of a settlement, the
settlement is conditioned upon a complete release by the claimant of the
Indemnified Party and (iii) such settlement or judgment does not require the
encumbrance of any asset of the Indemnified Party or impose any restriction upon
its conduct of business.

     12.5 Survival of Representations and Covenants of the Sellers and Allstate.
          ---------------------------------------------------------------------
Notwithstanding any right of the Company fully to investigate the affairs of
Allstate and notwithstanding any Knowledge of facts determined or determinable
by the Company pursuant to such investigation or right of investigation, the
Company shall have the right to rely fully upon the representations, warranties,
covenants and agreements of the Sellers and Allstate contained in this Agreement
or in any other Seller Document or Allstate Document.  With the sole exception
of those covenants which are to be performed by the Sellers after the Closing
(which shall survive until a claim thereon is barred by the applicable statute
of limitations), each representation, warranty, covenant and agreement of the
Sellers contained herein or in any Seller Document (whether or not made jointly
with Allstate) shall survive the execution and delivery of this Agreement and
the Closing and shall thereafter terminate and expire on the first anniversary
of the Closing Date, except that the representations and warranties of the
Sellers contained in Section 4.1 shall not terminate or expire and the
representations and warranties set forth in Sections 5.7 and 5.8 shall terminate
and expire ninety (90) days after the expiration of the statute of limitations
applicable to claims by third parties against the Company in respect of the
matter or matters which are the subject of such representations and warranties,
unless, or before such date, the Company has delivered to the Sellers a written
notice of a claim with respect to such representation, warranty, covenant or
agreement.

                                 ARTICLE XIII
                                 ------------
                             TERMINATION; REMEDIES
                             ---------------------

     13.1 Termination Without Default.  In the event that as of April 6, 2001,
          ---------------------------
any event or state of facts not constituting a default by either party shall
exist, which event or state of facts constitutes a failure of a condition
precedent for either party's benefit, the party for whose benefit such condition
precedent is imposed hereby shall have the right, at its sole option, to
terminate this Agreement prior to the Closing without liability to the other
party. Such right may be exercised by Allstate or the Sellers, as the case may
be, giving written notice to the other on or before the Closing Date, specifying
the event or state of facts giving rise to such right of termination.

     13.2 Termination Upon Default.  Either party may terminate this Agreement
          ------------------------
by giving notice to the other on or prior to the Closing Date, without prejudice
to any rights or obligations it may have, if (i) after written notice of the
default and the passage of (A) ten (10) Business Days, in the case of a default
which is by its nature incapable of being cured, or (B) thirty (30) Business
Days, or such shorter period as may end upon the scheduled Closing Date, in the
case of a default which by its nature is capable of being cured, the other party
has failed in the due and timely performance of any of its covenants or
agreements herein contained or there shall have been a breach of the other's
warranties or representations herein contained, and (ii) such failure or breach
could reasonably be expected to give the non-defaulting party grounds not to
close pursuant to Sections 9.1, 9.2, 10.1 or 10.2, as the case may be. In any
such event the party who is not guilty of the breach may, in addition to all of
its other rights and remedies, recover all Losses incurred by it from the party
responsible for the breach.

     13.3 Remedies of Sellers to be Pursued Collectively.  Any cause of action,
          ----------------------------------------------
litigation, arbitration, proceeding or other remedy of any nature against the
Company available to the Sellers, or any of them, in connection with the
transaction contemplated herein, whether arising from an actual or alleged
breach of representation, warranty or covenant of the Company hereunder or
arising from any actual or alleged act or omission in tort or otherwise, shall,
if it is pursued at all by any Seller, be pursued jointly by all Sellers, in one
unified action brought at the same time and in the same forum.  Any Seller who
does not join in such action shall be deemed to have waived any and all rights
in respect of such breach, act or omission.  Likewise, all decisions of the
Sellers relating in any manner to the prosecution of such action shall be made
jointly by the Sellers (in such manner and pursuant to such procedures as they
may agree upon among themselves) and shall bind all Sellers equally, it being
the intent of this Section 13.3 that the Company shall not in any manner be
subjected to any costs and burdens with respect to such remedy beyond the costs
and burdens which would be incurred by it in the ordinary course were the party
pursuing the remedy to be a single Person.

     13.4 Specific Performance.  The parties acknowledge that the Allstate
          --------------------
Shares are unique and cannot be obtained by the Company except from the Sellers
and for that reason, among others, the Company will be irreparably damaged in
the absence of the consummation of this Agreement. Therefore, in the event of
any breach by the Sellers or Allstate of this Agreement, the Company shall have
the right, at its election, to obtain an Order for specific

                                      39
<PAGE>

performance of this Agreement, without the need to post a bond or other
security, to prove any actual damage or to prove that money damages would not
provide an adequate remedy.

     13.5 Attorneys' Fees.  If any Seller, Allstate or the Company shall bring
          ---------------
an action against the other by reason of any alleged breach of any covenant,
provision or condition hereof, or otherwise arising out of this Agreement, the
unsuccessful party shall pay to the prevailing party all attorneys' fees and
costs actually incurred by the prevailing party, in addition to any other relief
to which it may be entitled.  If more than one Person is a party adverse to the
Company in any such action, however, such Persons shall designate one counsel to
represent all of them in the action and, if the Company is not the prevailing
party, the Company shall be required to pay the attorneys' fees of such one
counsel only.  As used in this Section 13.5 and elsewhere in this Agreement,
"actual attorneys' fees" or "attorneys' fees actually incurred" means the full
and actual cost of any legal services actually performed in connection with the
matter for which such fees are sought calculated on the basis of the usual fees
charged by the attorneys performing such services, and shall not be limited to
"reasonable attorneys' fees" as that term may be defined in statutory or
decisional Authority.

                                  ARTICLE XIV
                                  -----------
                           EXPENSES; CONFIDENTIALITY
                           -------------------------

     14.1 Expenses of Sale.  The Sellers shall bear their own direct and
          ----------------
indirect expenses and the direct and indirect expenses of Allstate incurred in
connection with the negotiation and preparation of this Agreement and the other
Seller Documents and Allstate Documents and the consummation and performance of
the transactions contemplated herein and therein from payments previously given
to the Sellers by the Company. The Sellers acknowledge that the Company has paid
to the Sellers an aggregate of $250,000 to be applied first, to the legal fees
and costs of LeBoeuf, Lamb, Greene & MacRae L.L.P. and second, all remaining
amounts to be remitted to an Affiliate of Allstate (Allstate Communications,
Inc.) for the account of the Company to be applied against outstanding payable
of the Company. Without limitation, such expenses shall include the fees and
expenses of all attorneys, accountants and other professionals incurred in
connection herewith, acting on behalf of Allstate or the Sellers. No such
expenses shall be charged against or paid by Allstate. By way of clarification,
all fees and expense incurred by the Sellers and Allstate of LeBoeuf, Lamb,
Greene & MacRae L.L.P. which shall be separately allocated and if previously
paid by Allstate shall be reimbursed by the Sellers from the $250,000 described
above.

     14.2 Confidentiality.  Subject to any obligation to comply with (i) any
          ---------------
Applicable Law (ii) any rule or regulation of any Authority or securities
exchange or (iii) any subpoena or other legal process to make information
available to the Persons entitled thereto, whether or not the transactions
contemplated herein shall be concluded, all information obtained by any party
about any other, and all of the terms and conditions of this Agreement, shall be
kept in confidence by each party, and each party shall cause its shareholders,
members, partners, directors, officers, managers, employees, agents and
attorneys to hold such information confidential.  Such confidentiality shall be
maintained to the same degree as such party maintains its own confidential
information and shall be maintained until such time, if any, as any such data or
information either is, or becomes, published or a matter of public knowledge.
If this Agreement

                                      40
<PAGE>

shall be terminated for any reason, each party shall return or cause to be
returned to the other all written data, information, files, records and copies
of documents, worksheets and other materials obtained by such party in
connection with the transactions contemplated herein.

     14.3 Publicity.  Up to (and including) the Closing Date, no publicity
          ---------
release or announcement concerning this Agreement or the transactions
contemplated herein shall be issued without advance written approval of the form
and substance thereof by the Company and the Sellers; provided, however, that to
the extent reasonably possible, such restrictions shall not apply to any
disclosure required by Authorities, Applicable Law or the rules of any
securities exchange which may be applicable provided, however, that the Sellers
shall be given the opportunity to comment on any publicity release or
announcement concerning this Agreement or the transactions contemplated herein
before such publicity release or announcement is issued. For a period of ten
(10) days after the Closing Date, the parties shall consult with each other
before issuing any press release or public statement with respect to this
Agreement or the transactions contemplated herein, and, except as may be
required by Applicable Law or the rules of any securities exchange which may be
applicable, will not issue any such press release or public statement prior to
such consultation. Neither the Sellers nor any officer, manager, employee,
director, member, partner, stockholder or other representative thereof shall, at
any time from and after the Closing, issue any press release or make any public
statement that is critical, disparaging or otherwise could reasonably be
interpreted as being negative with respect to Allstate or their respective
businesses, financial conditions, directors, officers, managers or employees.

           --------------------------------------------------
to the Closing Date or termination of this Agreement, the Company, on the one
hand, and the Sellers, on the other hand, may, by written agreement:

     16.3  Entire Agreement. This Agreement (including any exhibits hereto and

to be executed

                                      43
<PAGE>

and delivered pursuant hereto or thereto are intended to embody the final,
complete and exclusive agreement among the parties with respect to the purchase
of the Allstate Shares and related transactions; are intended to supersede all

respect thereto; and may not be contradicted by evidence of any such prior or
contemporaneous agreement, understanding or representation, whether written or
oral.

     16.4  Governing Law and Venue.  This Agreement is to be governed by and
           -----------------------
construed in accordance with the Applicable Laws of the State of California
pertaining to contracts made and to be performed wholly within such State, and
without regard to the conflicts of laws principles thereof. Any suit brought
hereon, whether in contract, tort, equity or otherwise, shall be brought in the
state or federal courts sitting in Los Angeles, California, the parties hereto
hereby waiving any claim or defense that such forum is not convenient or proper.
Each party hereby agrees that any such court shall have in personam jurisdiction
over it, consents to service of process in any manner prescribed in ARTICLE XV
or in any other manner authorized by California law, and agrees that a final
judgment in any such action or proceeding shall be conclusive and may be

specified by Applicable Law.

     16.5  Binding Effect. This Agreement and the rights, covenants, conditions
           --------------
and obligations of the respective parties hereto and any instrument or agreement
executed pursuant hereto shall be binding upon the parties and their respective
successors, assigns and legal representatives. Neither this Agreement, nor any
rights or obligations of any party hereunder, may be assigned by any Seller or
the Company without the prior written consent of the Company or the Sellers,
respectively; provided, however, that prior to or following the Closing, this
Agreement and any rights and obligations of the Company hereunder, and under any
Company Document may, without the prior written consent of the Sellers, be
assigned and delegated by the Company to any Person Affiliated with the Company
or pledged or hypothecated to any lender(s) of the Company or any such
Affiliate, and following the Closing, this Agreement and any rights and
obligations of the Company hereunder and under any Company Document may also be
assigned and delegated by the Company, without the prior written consent of the
Sellers, to any successor-in-interest of the Company to the Allstate Shares or
the assets and business of Allstate or to a substantial portion thereof;
provided, however, that no delegation by the Company of any such obligation
shall relieve the Company of liability therefor.

     16.6  Counterparts. This Agreement may be executed simultaneously in any
           ------------
number of counterparts, each of which shall be deemed an original of the party
or parties who executed such counterpart but all of which together shall
constitute one and the same instrument. In making proof of this Agreement it
shall not be necessary to produce or account for more than one counterpart
evidencing execution by each party hereto.

     16.7  Section Headings. The section headings of this Agreement are for
           ----------------
convenience of reference only and shall not be deemed to alter or affect any
provision hereof.

     16.8  Gender, Tense, Etc. Where the context or construction requires, all
           ------------------
words applied in the plural shall be deemed to have been used in the singular,
and vice versa; the masculine

shall include the past and future tense, and vice versa.

     16.9   Severability.  In the event that any provision or any part of any
            ------------
provision of this Agreement shall be void or unenforceable for any reason
whatsoever, then such provision shall be stricken and of no force and effect.
However, unless such stricken provision goes to the essence of the consideration
bargained for by a party, the remaining provisions of this Agreement shall
continue in full force and effect, and to the extent required, shall be modified
to preserve their validity.

     16.10  No Third-Party Rights. Nothing in this Agreement, whether express or
            ---------------------
implied, is intended to confer any rights or remedies under or by reason of this
Agreement on any Persons other than the parties to it and their respective
successors and assigns, nor is anything in this Agreement intended to relieve or
discharge the obligation or liability of any third Persons to any party to this
Agreement, nor shall any provision give any third Persons any right of
subrogation over or action against any party to this Agreement.

     16.11  Construction. The language in all parts of this Agreement shall in
            ------------
all cases be construed simply, according to its fair meaning, and not strictly
for or against any of the parties hereto. Without limitation, there shall be no
presumption against any party on the ground that such party was responsible for
drafting this Agreement or any part thereof.
