against it giving rise to any material Liability), except for (i) Liabilities

                        (iii) No claim has ever been made by an authority in a
                jurisdiction where the Target does not file Tax Returns that it
                is or may be subject to taxation by that jurisdiction, and the
                jurisdictions in which the Target is subject to taxation is set
                forth on Section 4(k) of the Disclosure Schedule.

                        (iv) There are no Security Interests on any of the
                assets of the Target that arose in connection with any failure
                (or alleged failure) to pay any Tax.

                        (v) The Target has withheld and paid all Taxes required
                to have been withheld and paid in connection with amounts paid
                or owing to any employee, independent contractor, creditor,
                unitholder, or other third party.

                        (vi) To the Knowledge of the Sellers, the Target does
                not expect any authority to assess any additional Taxes for any
                period for which Tax Returns have been filed. There is no
                dispute or claim concerning any Tax Liability of the Target
                either (A) claimed or raised by any authority in writing or (B)
                otherwise, to the Knowledge of the Sellers. Section 4(k) of the
                Disclosure Schedule lists all federal, state, local, and foreign
                income Tax Returns filed with respect to the Target for Taxable
                periods ended on or after December 31, 2000, indicates those Tax
                Returns that have been audited, and indicates those Tax Returns
                that currently are the subject of audit. The Target has
                delivered to the Buyer correct and complete copies of all
                federal income Tax Returns, examination reports, and statements
                of deficiencies assessed against or agreed to by the Target.

                        (vii) The Target currently is not the beneficiary of any
                extension of time within which to file any Tax Return. The
                Target has not waived any statute of limitations in respect of
                Taxes or agreed to any extension of time with respect to a Tax
                assessment or deficiency. No power of attorney is outstanding
                with respect to any Tax for which the Target may be responsible.

                        (viii) The Target is not a party to any Tax allocation
                or sharing agreement. The Target (A) has not been a member of an
                Affiliated Group filing a consolidated federal income Tax Return
                or (B) does not have any Liability for the Taxes of any Person
                (other than the Target) under Reg. Section 1.1502-6 (or any
                similar provision of state, local, or foreign law), as a
                transferee or successor, by contract, or otherwise. The Target
                is not included in a combined, unitary or similar Tax Return.

                        (ix) The unpaid Taxes of the Target (A) did not, as of
                the Most Recent Fiscal Month End, exceed the reserve for Tax
                Liability (rather than any reserve for deferred Taxes
                established to reflect timing differences between book and Tax
                income) set forth on the face of the Most Recent Balance Sheet
                (rather than in any notes thereto) delivered to the Buyer prior
                to the signing hereof and (B) do not exceed that reserve as
                adjusted for Taxes arising in the Ordinary Course of Business
                (e.g., FICA and state employment taxes) and for the passage of
                time through the Closing Date in accordance with the past custom
                and practice of the Target in filing its Tax Returns. The unpaid
                Taxes of the Target (other than Taxes


                                      -15-

                Date) as of the Closing Date do not exceed $30,000.

                        occurred that, with notice or lapse of time, would

                        modification, or acceleration thereunder;

                                (D) neither the Target nor, to the Knowledge of

                        thereunder have received all material approvals of

                        (i) The Target owns or has the right to use, execute,
                reproduce, display, perform, modify, enhance, distribute,
                prepare derivative works of, and to make, have made, sell,
                convey, transfer or assume without payments to any other Person,
                all Intellectual Property necessary or desirable for the
                operation of the business of the Target as presently conducted
                and as presently proposed to be conducted. Each item of
                Intellectual Property owned or used by the Target immediately
                prior to the Closing hereunder will be owned or available for
                use by the Target on identical terms and conditions immediately

                or refrain from using any Intellectual Property rights of any
                third party). To the Knowledge of any of the Sellers, no third
                party has interfered with, infringed upon, misappropriated, or
                otherwise come into conflict with any Intellectual Property
                rights of the Target.

                party owns and that the Target uses pursuant to license,

                        sublicense, agreement, or permission is in breach or
                        default, and no event has occurred that with notice or

                life insurance or other welfare-type benefits for current or
                future retired or terminated employees, their spouses, or their
                dependents (other than in accordance with Code Section 4980B).

                        (iv) The vesting, payment of, or entitlement to any
                benefits under, or the requirement of contributions to, or
                funding to any such Employee Benefit Plans, will not be
                accelerated as a result of the transactions contemplated by this
                Agreement. No amount that could be received (whether in cash or
                property or the vesting of property) as a result of the
                consummation of the transactions contemplated by this Agreement
                by any employee, officer or manager of the Target who is a
                "disqualified individual" (as such term is defined in proposed
                Treasury Regulation Section 1.280G-1) under any such Employee
                Benefit Plan could be characterized as an "excess parachute
                payment" (as defined in Code Section 280G(b)(1)).

                investigation, charge, complaint, claim, demand, or notice has

                prohibitions, requirements, obligations, schedules, and
                timetables that are contained in, all Environmental, Health, and
                Safety Laws.

                        (ii) The Target (and its predecessors, if any) does not
                have any Liability and has never handled or disposed of any

                demand against the Target giving rise to any Liability) for
                damage to any site, location, or body of water (surface or
                subsurface), for any illness of or personal injury to any
                employee or other individual, or for any reason under any
                Environmental, Health, and Safety Law.

                (aa) Certain Business Relationships with the Target. None of the
Sellers and their respective Affiliates has been involved in any business
arrangement or relationship, other than an employment relationship, with the
Target within the past 12 months, and none of the Sellers and their respective
Affiliates owns any asset, tangible or intangible, that is used in the business
of the Target.

                (bb) Disclosure. The representations and warranties contained in
this Section 4 do not contain any untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements and
information contained in this Section 4 not misleading.

        5. Pre-Closing Covenants. The Parties agree as follows with respect to
the period between the execution of this Agreement and the Closing.

                (a) General. Each of the Parties will use his or its
commercially reasonable efforts to take all action and to do all things
necessary, proper, or advisable in order to consummate and make effective the
transactions contemplated by this Agreement (including satisfaction, but not
waiver, of the closing conditions set forth in Section 7 below).

                (b) Notices and Consents. The Sellers will cause the Target to
give any notices to third parties, and will cause the Target to use its
commercially reasonable efforts to obtain any necessary third party consents in
connection with the matters referred to in Section 4(c) above. Each of the
Parties will (and the Sellers will cause the Target to) give any notices to,
make any filings with, and use his or its commercially reasonable efforts to
obtain any authorizations, consents, and approvals of governments, governmental
agencies and other third parties in connection with the matters referred to in
Section 3(a)(i), Section 3(b)(ii), and Section 4(c) above.

                (c) Operation of Business. The Sellers will not cause or permit
the Target to engage in any practice, take any action, or enter into any
transaction outside the Ordinary Course of Business. Without limiting the
generality of the foregoing, the Sellers will not cause or permit the Target to
engage in any practice, take any action, or enter into any transaction of the
sort described in Section 4(h) above without the prior written consent of the
Buyer.

                (d) Preservation of Business. The Sellers will use commercially
reasonable efforts to cause the Target to keep its business and properties
substantially intact, including its present operations, physical facilities,
working conditions, and relationships with lessors, licensors, suppliers,
customers, and employees.

                (e) Full Access. Each of the Sellers will permit, and the
Sellers will cause the Target to permit, representatives of the Buyer to have
full access at all reasonable times to all premises, properties, personnel,
books, records (including Tax records), contracts, and documents of or
pertaining to the Target.

                (f) Notice of Developments. The Sellers will give prompt written
notice to the Buyer of any material adverse development causing a breach of any
of the representations and warranties in Section 4 above. Each Party will give
prompt written notice to the others of any


                                      -26-
<PAGE>

material adverse development causing a breach of any of his or its own
representations and warranties in Section 3 above. No disclosure by any Party
pursuant to this Section 5(f), however, shall be deemed to amend or supplement
Annex I or the Disclosure Schedule or to prevent or cure any misrepresentation,
breach of warranty, or breach of covenant.

                (g) Exclusivity. None of the Sellers will (and the Sellers will
not cause or permit the Target to) (i) solicit, initiate, or encourage the
submission of any proposal or offer from any Person relating to the acquisition
of any equity interests or other voting securities, or any substantial portion
of the assets of the Target (including any acquisition structured as a merger,
consolidation, share exchange or otherwise) or (ii) participate in any
discussions or negotiations regarding, furnish any information with respect to,
assist or participate in, or facilitate in any other manner any effort or
attempt by any Person to do or seek any of the foregoing. None of the Sellers
will vote his Class A Units in favor of any such acquisition. The Sellers will
notify the Buyer within two (2) days if any Person makes any proposal, offer,
inquiry, or contact with respect to any of the foregoing and will disclose the
details of a proposal or offer, including the Person or Persons making it and
the material terms of such proposal or offer.

                (h) Restricted Units. Immediately prior to the Closing, the
Target shall take all action necessary to cause all restrictions in respect of
the Class A Units issued under the Target Plan to lapse.

                (i) Tax Election. No Seller, or any manager or officer of the
Target, shall make any election or take any other action on behalf of, or with
respect to, the Target that is inconsistent with how the Target has filed its
prior Tax Returns and would increase the Target's Liability for Taxes for any
Taxable period (including a past, present or future Taxable period).

                (j) Valuation of the Target's Assets for Income Tax Purposes.
The Buyer and the Seller Representatives shall use commercially reasonable
efforts to agree upon the value of each Target asset for income tax purposes
and, if and upon reaching such agreement, shall attach as Schedule 2 hereto a
written memorandum of such within five (5) business days of the date of this
Agreement. If the Buyer and the Seller Representatives are unable to so agree
within said five (5) day period, the Buyer and the Seller Representatives shall
mutually select an independent "Big 5" accounting firm to perform such valuation
on or prior to the Closing, and such firm's valuation shall be conclusive on all
Parties hereto and shall be set forth as Schedule 2 hereto. Schedule 2 shall
automatically become a part of this Agreement after it has been prepared in
accordance with this Section 5(j). If an accounting firm is selected to perform
a valuation in accordance with this Section 5(j), each of (i) the Buyer and (ii)
the Sellers shall pay one-half of the fees and expenses of such firm for such
valuation. No Party shall take any position for income tax purposes that is
inconsistent in any material respect with Schedule 2.

        6. Post-Closing Covenants. The Parties agree as follows with respect to
the period following the Closing.

                (a) General. In case at any time after the Closing any further
action is necessary or desirable to carry out the purposes of this Agreement,
each of the Parties will take such further action (including the execution and
delivery of such further instruments


                                      -27-
<PAGE>

and documents) as any other Party may reasonably request, all at the sole cost
and expense of the requesting Party (unless the requesting Party is entitled to
indemnification therefor under Section 8 below). The Sellers acknowledge and
agree that from and after the Closing the Buyer will be entitled to possession
of all documents, books, records (including Tax records), agreements, and
financial data of any sort relating to the Target.

                (b) Litigation Support. In the event and for so long as any
Party actively is contesting or defending against any action, suit, proceeding,
hearing, investigation, charge, complaint, claim, or demand in connection with
(i) any transaction contemplated under this Agreement or (ii) any fact,
situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act, or transaction on or prior
to the Closing Date involving the Target, each of the other Parties will
cooperate with him or it and his or its counsel in the contest or defense, make
available his or its personnel, and provide such testimony and access to his or
its books and records as shall be necessary in connection with the contest or
defense, all at the sole cost and expense of the contesting or defending Party
(unless the contesting or defending Party is entitled to indemnification
therefor under Section 8 below).

                (c) Transition. None of the Sellers will take any action that is
designed or intended to have the effect of discouraging any lessor, licensor,
customer, supplier, or other business associate of the Target from maintaining
the same business relationships with the Target after the Closing as it
maintained with the Target prior to the Closing. Each of the Sellers will refer
all customer inquiries relating to the business of the Target to the Target from
and after the Closing.

                (d) Confidentiality. Each of the Sellers will treat and hold as
such all of the Confidential Information, refrain from using any of the
Confidential Information, except in connection with this Agreement and in
connection with such Seller's employment by the Target to the extent any such
Seller remains an employee of the Target, and deliver promptly to the Buyer or
destroy, at the request and option of the Buyer, all tangible embodiments (and
all copies) of the Confidential Information that are in his possession to the
extent any such Seller ceases to be an employee of the Target. In the event that
any of the Sellers is requested or required (by oral question or request for
information or documents in any legal proceeding, interrogatory, subpoena, civil
investigative demand, or similar process) to disclose any Confidential
Information, that Seller will notify the Buyer promptly of the request or
requirement so that the Buyer may seek an appropriate protective order or waive
compliance with the provisions of this Section 6(d). If, in the absence of a
protective order or the receipt of a waiver hereunder, any of the Sellers is, on
the advice of counsel, compelled to disclose any Confidential Information to any
tribunal or else stand liable for contempt, that Seller may disclose the
Confidential Information to the tribunal; provided, however, that the disclosing
Seller shall use his reasonable efforts to obtain, at the request of the Buyer
and at the Buyer's expense, an order or other assurance that confidential
treatment will be accorded to such portion of the Confidential Information
required to be disclosed as the Buyer shall designate. The foregoing provisions
shall not apply to any Confidential Information that is generally available to
the public immediately prior to the time of disclosure.

                to adjust the terms of all outstanding Options, whether vested
                or unvested, as necessary to provide that each Option
                outstanding immediately prior to the Closing shall be amended
                and converted into an option to acquire, on the same terms and
                conditions as were applicable under such Option, the number of
                shares of Buyer Common Stock (rounded down to the nearest whole
                share) equal to (A) the number of Class A Units subject to such
                Option immediately prior to the Closing multiplied by (B) the
                Exchange Ratio, at an exercise price per share of Buyer Common
                Stock (rounded up to the nearest whole cent) equal to (x) the
                exercise price per Class A Unit otherwise purchasable pursuant
                to such Option immediately prior to the Closing divided by (y)
                the Exchange Ratio (each, as so adjusted, an "Adjusted Option").

                        (ii) Except to the extent required under the respective
                terms of the Options, all restrictions or limitations on
                transfer and vesting with respect to Options awarded under the

                shall not have already lapsed, and all other terms thereof,
                shall remain in full force and effect after giving effect to the
                transactions contemplated in Section 2 above.

                        (iii) As soon as reasonably practicable following the
                Closing, the Buyer shall prepare and file with the SEC a
                registration statement on Form S-8 (or another appropriate form)
                registering the number of shares of Buyer Common Stock subject
                to the Adjusted Options and shall maintain the effectiveness of
                such registration statement (and maintain the current status of
                the prospectus contained therein) for so long as any such
                Adjusted Options remain outstanding.

                (f) Registration of Registrable Shares.

                        (i) If the Closing occurs in calendar year 2001, within
                forty-five (45) days after the Closing Date, the Buyer shall
                file with the SEC a registration statement on any appropriate
                form under the Securities Act with respect to the offering and
                sale or other disposition of the Registrable Shares. If the
                Closing occurs in calendar year 2002, the Buyer shall have up to
                ninety (90) days to file such registration statement. The Buyer
                shall use all commercially reasonable efforts to cause such
                registration statement to become effective as soon as reasonably
                practicable after such filing. The Sellers shall cooperate with
                and provide assistance to the Buyer, as the Buyer may reasonably
                request, in connection with any registration and sale of the
                Registrable Shares.

                        (ii) The Buyer shall (i) prepare and file with the SEC,
                any amendments or supplements to such registration statement or

                                      -29-
<PAGE>

                to keep such registration statement effective and to comply with
                the provisions of the Securities Act with respect to the offer
                of the Registrable Shares covered by such registration statement
                for a period of twelve months from the effective date of the
                registration statement; (ii) prepare and promptly file with the
                SEC and promptly notify the Sellers of the filing of such
                amendment or supplement to such registration statement or
                prospectus as may be necessary to correct any statement therein
                or omission therefrom if, at any time when a prospectus relating
                to the Registrable Shares is required to be delivered under the
                Securities Act, any event with respect to the Buyer shall have
                occurred as a result of which any prospectus would include an
                untrue statement of material fact or omit to state any material
                fact necessary to make the statements therein not misleading;
                (iii) in case the Sellers are required to deliver a prospectus,
                prepare promptly such amendment or amendments to such
                registration statement and such prospectus or prospectuses as
                may be necessary to permit compliance with the requirements of
                Section 10(a)(3) of the Securities Act; (iv) advise the Sellers
                promptly after the Buyer shall receive notice or obtain
                knowledge of the issuance of any stop order by the SEC
                suspending the effectiveness of any such registration statement
                or amendment thereto or of the initiation or threatening of any
                proceedings for that purpose, and promptly use commercially
                reasonable efforts to prevent the issuance of any stop order or
                to obtain its withdrawal if such stop order should be issued;
                (v) use commercially reasonable efforts to qualify such
                Registrable Shares for sale under the securities or "blue sky"
                laws of such states within the United States as the Sellers may
                reasonably designate, except that the Buyer shall not be
                required in connection therewith or as a condition thereto to
                qualify to do business in any such state or to take any action
                that would subject it to general service of process in any such
                jurisdiction where it is not then so subject; and (vi) furnish
                to the Sellers, as soon as available, copies of any such
                registration statement and each preliminary and final
                prospectus, or supplement or amendment required to be prepared
                with respect thereto, all in such quantities as they may from
                time to time reasonably request.

                        (iii) The Sellers agree that, upon receipt of any notice
                from the Buyer of the happening of any event of the kind
                described in Section 6(f)(ii), they will forthwith discontinue
                the disposition of the Registrable Shares until they have
                received copies of the supplemented or amended prospectus
                contemplated by Section 6(f)(ii), or until the Sellers are
                advised in writing by the Buyer that the use of the prospectus
                may be resumed, and have received copies of any additional or
                supplemental filings that are incorporated by reference in the
                prospectus, and, if so directed by the Buyer, the Sellers will
                deliver to the Buyer all copies, other than permanent file
                copies, then in the Sellers' possession of the prospectus
                covering the Registrable Shares current at the time of receipt
                of such notice.

                        (iv) If the Buyer takes any action to permit a public
                offering or sale or other distribution of such Registrable
                Shares, the Sellers shall furnish information to the Buyer
                concerning the Sellers' holdings of securities of the Buyer and
                the proposed method of sale or other disposition of the
                Registrable Shares and such other information and undertakings
                as shall be required in connection with the


                                      -30-
<PAGE>

                preparation and filing of any registration statement and any
                amendments thereto covering all or part of the Registrable
                Shares in order to assist the Buyer in complying with the
                Securities Act and the Securities Exchange Act. The Sellers
                further agree to enter into such undertakings and take such
                other action relating to the conduct of the proposed offering
                that the Buyer may reasonably request as being necessary to
                assist the Buyer in complying with the federal and state
                securities laws and the rules or other requirements of the
                National Association of Securities Dealers, Inc. ("NASD") or
                otherwise to effectuate the offering.

                        (v) The Buyer shall pay all registration expenses
                incident to the registration of the Registrable Shares
                including, without limitation, all registration, filing and NASD
                fees, all fees and expenses of complying with securities or blue
                sky laws, all word processing, duplicating and printing
                expenses, messenger and delivery expenses, and the fees and
                disbursements of counsel for the Buyer and of its independent
                public accountants, including the expenses of any special audits
                or "cold comfort" letters required by or incident to such
                performance and compliance. With respect to sales of Registrable
                Shares, the Sellers shall pay all underwriting discounts and
                commissions and fees of underwriters, selling brokers, dealer
                managers or similar securities industry professionals relating
                to the distribution of the Registrable Shares, and the fees and
                disbursements of counsel retained by the Sellers and transfer
                taxes, if any.

                (g) Business Location. It is the intent of the Parties that the
business of the Target will continue to be conducted in the greater metropolitan
Phoenix area; provided, however, that the Buyer may after the Closing in its
sole discretion move the business of the Target to any other area.

                (h) Employment Matters. With respect to employee retirement,
welfare and fringe benefit plans, policies or programs of the Buyer (the "Buyer
Employee Plans"), each Person who was an employee of the Target at the Closing
(the "Target Employee") is allowed to participate in or entitled to the
following after the Closing: (i) the Buyer will provide the Target Employee with
service credit in an amount equal to the service credit accrued prior to the
Closing, if any, under the Target's plans, policies, programs, agreements and
arrangements, and each Target Employee will be so recognized for purposes of
participation, eligibility and vesting, but not for purposes of benefit accrual,
under the Buyer Employee Plans and (ii) the Buyer will use commercially
reasonable efforts to cause its benefit providers to waive all waiting periods
and pre-existing condition requirements under any Buyer Employee Plan that has
any such requirements or restrictions. Without limiting the foregoing, the Buyer
will assume any accrued but unused vacation days, and any earned but unused sick
days, credited to each Target Employee under the Target's applicable vacation
and sick leave policies as of the Closing; it being understood that each Target
Employee will accrue vacation days and earn sick days for service following the
Closing in accordance with the applicable vacation and sick leave policies of
the Buyer.

                (i) Intellectual Property. At all times after the Closing Date,
each Seller shall assist the Buyer in every proper way to obtain and prosecute
all patent applications in which such Seller is an inventor thereunder. The
Buyer shall (i) compensate such Seller at a reasonable rate


                                      -31-

if such Seller is not an employee of the Buyer at the time he is rendering such
assistance and (ii) reimburse all reasonable expenses of such Seller in
connection with his assistance.

        8. Remedies for Breaches of This Agreement.

suffered by any of them arising out of or based upon any of the following
matters:

                        (i) fraud, intentional misrepresentation or the willful
                breach of any representations, warranties or covenants of the

                annex or exhibit delivered pursuant hereto (collectively, "Fraud
                Claims");

                        (ii) any Liability arising from any breach of the
                representations and warranties set forth in Sections 3(a)(i),
                3(a)(iv), 3(a)(v), 4(a), 4(b) and 4(f) (collectively, "Ownership

                        (iii) any Liability for Taxes arising from the Target's
                income, activities, assets, events, circumstances and
                transactions on or prior to the Closing (to the extent such
                Liability for Taxes (other than Taxes required to be reflected
                on Tax Returns due prior to the Closing Date) exceeds $30,000)
                or any breach of the representations and warranties set forth in
                Sections 4(k) and 4(x) hereof or the covenants set forth in

<PAGE>

                        (iv) any Liability arising from any breach of the
                environmental representations and warranties set forth in
                Section 4(z) hereof (collectively, "Environmental Claims");

                        (v) any Liability arising from acts or omissions of any
                of the Seller Representatives or any disputes among the Sellers
                or between the Sellers and the Seller Representatives for the
                allocation of the Purchase Price or otherwise (collectively,
                "Allocation Claims"); and

                        (vi) other than Fraud Claims, Ownership Claims, Tax
                Claims, Environmental Claims and Allocation Claims, any other
                breach of any representation, warranty or covenant of the
                Sellers under this Agreement or in any schedule, annex or
                exhibit delivered pursuant hereto, or by reason of any claim,
                action or proceeding asserted or instituted growing out of any
                matter or thing constituting a breach of such representations,
                warranties or covenants (collectively, "General Claims").

                (b) Limitations on Indemnification by the Sellers. Anything
contained in this Agreement to the contrary notwithstanding, the Liability of
the Sellers to provide any indemnification to any Buyer Indemnified Party and
the right of the Buyer Indemnified Parties to indemnification under Section 8(a)
shall be subject to the following provisions:

                        (i) No claims for indemnification shall be made under
                this Agreement against the Sellers, and no indemnification shall
                be payable to any Buyer Indemnified Party, with respect to
                General Claims after the date that is two years following the
                Closing (except for those claims that were initiated prior to
                such two-year limitation).

                        (ii) No claims for indemnification shall be made under
                this Agreement against the Sellers, and no indemnification shall
                be payable to any Buyer Indemnified Party, with respect to any
                Tax Claim or Environmental Claim after expiration of all
                applicable statutes of limitation with respect to the Tax Claim
                or Environmental Claim, as applicable.

                        (iii) In no event shall the maximum aggregate Liability
                of the Sellers under Section 8(a) with respect to General
                Claims, Environmental Claims and Tax Claims exceed $13,161,529;
                provided, however, that this Section 8(a)(iii) shall not apply
                to any obligation or covenant of the Sellers to pay or reimburse
                money to the Buyer that is expressly set forth in this
                Agreement.

                        (iv) The Sellers shall not be liable under Section 8(a)
                with respect to General Claims, Environmental Claims and Tax
                Claims until the amount otherwise due to the Buyer Indemnified
                Parties exceeds $100,000 in the aggregate, in which case the
                Sellers will be liable to the Buyer Indemnified Parties for the
                full amount due (excluding all amounts below $100,000);
                provided, however, that this Section 8(a)(iv) shall not apply to
                any obligation or covenant of the Sellers to pay or reimburse
                money to the Buyer that is expressly set forth in this
                Agreement.

<PAGE>

                        (v) Claims for indemnification with respect to Fraud
                Claims, Ownership Claims and Allocation Claims made under this
                Agreement by any Buyer Indemnified Party shall not be subject to
                any of the limitations set forth in this Section 8(b).

                (c) Indemnification by the Buyer. The Buyer agrees to indemnify
and hold the Sellers harmless from and against any Adverse Consequences that may
be sustained or suffered by any or all of them arising out of or based upon any
of the following matters:

                        (i) fraud, intentional misrepresentation or the willful
                breach of any representations, warranties or covenants of the
                Buyer under this Agreement or in any certificate, schedule,
                annex or exhibit delivered pursuant hereto;

                        (ii) any breach of any representation, warranty or
                covenant made by the Buyer in this Agreement or in any
                certificate delivered by the Buyer hereunder, or by reason of
                any claim, action or proceeding asserted or instituted growing
                out of any matter or thing constituting such a breach; and

                        (iii) the operation of the business of the Target
                following the Closing Date; except to the extent such Adverse
                Consequences are attributable to acts or circumstances occurring
                prior to the Closing Date.

                (d) Limitation on Indemnification by the Buyer. Anything
contained in this Agreement to the contrary notwithstanding, no claim for
indemnification shall be made under this Agreement against the Buyer, and no
indemnification shall be payable to the Sellers with respect to claims asserted
pursuant to Section 8(c) above, after the date that is two years following the
Closing (except for those claims that were initiated prior to such two-year
limitation). In no event shall the maximum aggregate Liability of the Buyer
under Section 8(c) exceed $13,161,529. In addition, the Buyer shall not be
liable under Section 8(c) until the amount otherwise due to the Sellers exceeds
$100,000 in the aggregate, in which case the Buyer will be liable to the Sellers
for the full amount due (excluding all amounts below $100,000). Notwithstanding
the foregoing, claims for indemnification with respect to fraud, intentional
misrepresentation or the willful breach of any representations, warranties or
covenants of the Buyer under this Agreement or in any certificate, schedule,
annex or exhibit delivered pursuant hereto shall not be subject to any of the
limitations set forth in this Section 8(d).

                (e) Notice; Defense of Claims. An indemnified party shall make
claims for indemnification hereunder by giving written notice thereof to the
indemnifying party promptly on discovery and in any event within the period in
which indemnification claims can be made hereunder. If indemnification is sought
for a claim or Liability asserted by a third party, the indemnified party shall
also give written notice thereof to the indemnifying party promptly after it
receives notice of the claim or Liability being asserted, but the failure to do
so shall not relieve the indemnifying party from any Liability except to the
extent that it is materially prejudiced by the failure or delay in giving such
notice. Such notice shall summarize the basis for the claim for indemnification
and any claim or Liability being asserted by a third party. Within twenty (20)
days after receiving such notice the indemnifying party shall give written
notice to the indemnified party stating whether it disputes the claim for
indemnification and whether it will


                                      -36-
<PAGE>

defend against any third party claim or Liability at its own cost and expense.
If the indemnifying party fails to give notice that it disputes an
indemnification claim within twenty (20) days after receipt of notice thereof,
it shall be deemed to have accepted and agreed to the claim, which shall become
immediately due and payable. The indemnifying party shall be entitled to direct
the defense against a third-party claim or Liability with counsel selected by it
(subject to the consent of the indemnified party, which consent shall not be
unreasonably withheld or delayed) as long as the indemnifying party is
conducting a good faith and diligent defense. The indemnified party shall at all
times have the right to fully participate at its own expense in the defense of a
third-party claim or Liability, directly or through counsel; provided, however,
that if the named parties to the action or proceeding include both the
indemnifying party and the indemnified party and the indemnified party is
advised that representation of both parties by the same counsel would be
inappropriate under applicable standards of professional conduct, the
indemnified party may engage separate counsel at the expense of the indemnifying
party. If no such notice of intent to dispute and defend a third-party claim or
Liability is given by the indemnifying party, or if such good faith and diligent
defense is not being or ceases to be conducted by the indemnifying party, the
indemnified party shall have the right, at the expense of the indemnifying
party, to undertake the defense of such claim or Liability (with counsel
selected by the indemnified party), and to compromise or settle it, with consent
of the indemnifying party, which consent shall not be unreasonably withheld or
delayed. If the third party claim or Liability is one that by its nature cannot
be defended solely by the indemnifying party, then the indemnified party shall
make available such information and assistance as the indemnifying party may
reasonably request and shall cooperate with the indemnifying party in such
defense, at the expense of the indemnifying party.

                (f) Security for the Sellers' Indemnification Obligations. As
security for the agreement by the Sellers to indemnify the Buyer as described in
this Section 8, each Seller hereby instructs the Buyer to set aside and deposit
into escrow with Computershare Trust Company, Inc, as escrow agent (the "Escrow
Agent"), in accordance with the Escrow Agreement the Held Back Consideration.
The Buyer may set off against the Held Back Consideration any indemnification
claims for which the Sellers may be responsible pursuant to this Agreement.

                (g) Currency Exchange. For purposes of the Held Back
Consideration as security for the indemnification provisions set forth in this
Agreement, the value given to each share of Buyer Common Stock held as Held Back
Consideration that is used at any time to satisfy indemnification claims of the
Buyer shall be $17.00 (the "Currency Exchange"). In the event that the market
price of the Buyer Common Stock increases or decreases while there is Held Back
Consideration subject to the Escrow Agreement, the Sellers shall retain the
Currency Exchange value per share for purposes of fulfilling any indemnification
obligation from the Held Back Consideration.

                (h) Held Back Consideration Not Exclusive. Each Buyer
Indemnified Party shall have the right to satisfy its indemnification claims out
of the escrow created by the Escrow Agreement and pursuant to the terms thereof,
and the Sellers shall have no right to satisfy any indemnification claims of any
Buyer Indemnified Party outside of the Escrow Agreement; provided, however, that
the Held Back Consideration shall not be the Buyer's exclusive source of
indemnification from the Sellers pursuant to this Section 8. The foregoing
indemnification provisions are in addition to, and not in derogation of, any
statutory, equitable, or common law


                                      -37-
<PAGE>

remedy any Party may have for breach of representation, warranty, or covenant.
Each of the Sellers hereby agrees that he will not make any claim for
indemnification against the Target by reason of the fact that he was a manager,
officer, employee, or agent of the Target or was serving at the request of the
Target as a partner, manager, trustee, director, officer, employee, or agent of
another entity (whether such claim is for judgments, damages, penalties, fines,
costs, amounts paid in settlement, losses, expenses, or otherwise and whether
such claim is pursuant to any statute, charter document, bylaw, operating
agreement, contract or otherwise) with respect to any action, suit, proceeding,
complaint, claim, or demand brought by the Buyer against such Seller (whether
such action, suit, proceeding, complaint, claim, or demand is pursuant to this
Agreement, applicable law, or otherwise).

        9. Tax Matters. The following provisions shall govern the allocation of
responsibility as between the Buyer and the Sellers for certain tax matters
following the Closing Date:

                (a) Characterization of the Transaction. The Parties agree that
the transaction will be reported on all applicable Tax Returns in a manner
consistent with the following:

                        (i) No Party will take a position on a Tax Return
                contrary to the covenants and representations set forth in this
                Agreement, including those set forth below in this Section 9(a);

                        (ii) Each Seller will treat the sale of the Class A
                Units as a sale or exchange of a partnership interest pursuant
                to Code Section 741, except as otherwise provided in Code
                Section 751;

                        (iii) The Buyer will treat the purchase of the Class A
                Units as an acquisition of all of the assets of the Target;

                        (iv) The Target will terminate pursuant to Code Section
                708 as a result of, and immediately upon, the acquisition of the
                Class A Units; and

                        (v) The Buyer shall have no obligation for the federal
                and state income Taxes payable with respect to the transactions
                of the Target that accrued on or prior to the Closing Date, and
                the Sellers shall have no obligation for the federal and state
                income Taxes payable with respect to the transactions of the
                Target that accrue after the Closing Date.

                (b) Tax Periods Ending on or Before the Closing Date. The
Sellers shall prepare or cause to be prepared and file or cause to be filed all
income Tax Returns for the Target for all periods ending on or prior to the
Closing Date but due thereafter. The Sellers shall permit the Buyer to review
and comment on each such Tax Return described in the preceding sentence prior to
filing. All such Tax Returns shall be prepared in a manner consistent with past
practice and, without the Buyer's written consent (which may be granted or
withheld in its sole and absolute discretion), no positions shall be taken,
elections made, or method adopted that is inconsistent with positions taken,
elections made, or methods used in preparing and filing similar Tax Returns in
prior periods (including, but not limited to, positions, elections or methods
that would have the effect of deferring income or gains to a period after the
Closing or accelerating


                                      -38-
<PAGE>

deductions or losses to a period prior to the Closing). The Buyer shall prepare
or cause to be prepared and file or cause to be filed all non-income Tax Returns
for the Target for all periods ending on or prior to the Closing Date that are
due to be filed after the Closing Date. The Buyer shall permit the Seller
Representatives to review and comment on each such Tax Return described in the
preceding sentence prior to filing. All such Tax Returns shall be prepared in a
manner consistent with past practice and, on such Tax Returns, no positions
shall be taken, elections made, or method adopted that is inconsistent with
positions taken, elections made, or methods used in preparing and filing similar
Tax Returns in prior periods, unless counsel to the Buyer advises it that taking
a position, making or following an election or using a method consistent with
Tax Returns filed for prior periods is not supported by law or is likely to
expose the Target or the Buyer to penalties.

                (c) Tax Periods Beginning Before and Ending After the Closing
Date. The Buyer shall prepare or cause to be prepared and file or cause to be
filed any non-income Tax Returns of the Target for Tax periods that begin before
the Closing Date and end after the Closing Date. All such Tax Returns shall be
prepared in a manner consistent with past practice and, on such Tax Returns, no
positions shall be taken, elections made, or method adopted that is inconsistent
with positions taken, elections made, or methods used in preparing and filing
similar Tax Returns in prior periods, unless counsel to the Buyer advises it
that taking a position, making or following an election or using a method
consistent with Tax Returns filed for prior periods is not supported by law or
is likely to expose the Target or the Buyer to penalties.

                (d) Cooperation on Tax Matters.

                        (i) The Buyer, the Target and the Sellers shall
                cooperate fully, as and to the extent reasonably requested by
                the other party, in connection with the filing of Tax Returns
                pursuant to this Section 9 and any audit, litigation or other
                proceeding with respect to Taxes. Such cooperation shall include
                the retention and (upon the other party's reasonable request)
                the provision of records and information that are reasonably
                relevant to any such audit, litigation or other proceeding and
                making employees available on a mutually convenient basis to
                provide additional information and explanation of any material
                provided hereunder. The Target and the Sellers shall (A) retain
                all books and records with respect to Tax matters pertinent to
                the Target relating to any Taxable period beginning before the
                Closing Date until the expiration of the statute of limitations
                (and, to the extent notified by the Buyer or the Sellers, any
                extensions thereof) of the respective Taxable periods, and to
                abide by all record retention agreements entered into with any
                taxing authority, and (B) give the Buyer reasonable written
                notice prior to transferring, destroying or discarding any such
                books and records and, if the other party so requests, the
                Target or the Sellers, as the case may be, shall allow the other
                party to take possession of such books and records.

                        (ii) The Buyer and the Sellers shall, upon request, use
                commercially reasonable efforts to obtain any certificate or
                other document from any governmental authority or any other
                Person as may be necessary to mitigate, reduce or eliminate any
                Tax that could be imposed (including, but not limited to, with
                respect to the transactions contemplated hereby).


                                      -39-
<PAGE>

                (e) Tax Sharing Agreements. The Sellers hereby represent and
covenant that there are no tax sharing agreements or similar agreements with
respect to or involving the Target and that the Target has no Liability with
respect to such an agreement.

                (f) Certain Taxes. All transfer, documentary, sales, use, stamp,
registration and other such Taxes and fees (including any penalties and
interest) incurred in connection with the Seller's sale of their respective
Units shall be paid by the Sellers when due, and the Sellers will, at their own
expense, file all necessary Tax Returns and other documentation with respect to
all such transfer, documentary, sales, use, stamp, registration and other Taxes
and fees, and, if required by applicable law, the Buyer will, and will cause its
Affiliates to, join in the execution of any such Tax Returns and other
documentation.

                (g) Indemnification Payments. Any payments by a Party pursuant
to Section 8 shall be considered an adjustment to the Purchase Price for all
income and local tax purposes.

        10. Seller Representatives.

                (a) Appointment. As used in this Agreement, the "Seller
Representatives" means Richard S. Torkington, Dean L. Cook and David W. Corman
or any person appointed as a successor Seller Representative pursuant to Section
10(b) below. The written approval of at least two of the three Seller
Representatives is required for any action of the Seller Representatives under
this Agreement or the Escrow Agreement.

                (b) Election and Replacement. From and after the date hereof
until the date when all obligations under this Agreement have been discharged
(including all indemnification obligations under Section 8 hereof), the Sellers
representing a majority in interest of the Class A Units may, from time to time
upon written notice to the Seller Representatives and the Buyer, remove any of
the Seller Representatives (including any appointed by the Buyer) or appoint a
new Seller Representative to fill any vacancy created by the death,
incapacitation, resignation or removal of a Seller Representative. Furthermore,
if any Seller Representative dies, becomes incapacitated, resigns or is removed
by the Sellers representing a majority in interest of the Class A Units, the
Sellers shall promptly appoint a successor Seller Representative to fill the
vacancy so created. If the Sellers representing a majority in interest of the
Class A Units are required to but have not appointed a successor Seller
Representative within twenty (20) days from a request by the Buyer to appoint a
successor Seller Representative, the Buyer shall have the right to appoint a
Seller Representative to fill any vacancy so created from the managers of the
Target prior to the Closing Date, and shall advise the Seller Representatives of
such appointment by written notice. A copy of any appointment by the Sellers of
any successor Seller Representative shall be provided to the Buyer promptly
after it shall have been effected.

                (c) Authority. In addition to any other authority granted to the
Seller Representatives herein, after the Closing Date the Seller Representatives
shall be authorized to enter into and perform their obligations under the Escrow
Agreement, and to discuss, negotiate, resolve and fully and finally settle on
behalf of the Sellers any claims for indemnification by the Buyer against the
Sellers under Section 8 hereof and any disputes arising out of this Agreement
and to take any action and to make and deliver any certificate, notice, consent
or instrument required or permitted to be made or delivered under this Agreement
or under the documents referred to in


                                      -40-
<PAGE>

this Agreement (an "Instrument") that the Seller Representatives determine in
their discretion to be necessary, appropriate or desirable, and, in connection
therewith, to hire or retain, at the sole expense of the Sellers, such counsel,
investment bankers, accountants, and other professional advisors as they
determine in their sole and absolute discretion to be necessary, advisable or
appropriate in order to carry out and perform their rights and obligations
hereunder. Any party receiving an Instrument from the Seller Representatives
shall have the right to rely in good faith upon such Instrument, and to act in
accordance with the Instrument without independent investigation.

                (d) No Liability of the Buyer. The Buyer shall have no Liability
to any of the Sellers or otherwise arising out of the acts or omissions of the
Seller Representatives or any disputes among the Sellers or between the Sellers
and the Seller Representatives. The Buyer may rely entirely on its dealings
with, and notices to and from, the Seller Representatives to satisfy any
obligations it might have under this Agreement or otherwise to the Sellers. The
Sellers shall indemnify the Buyer for any Adverse Consequences suffered as a
result of the Buyer's good faith reliance on the acts or omissions of the Seller
Representatives.

        11. Termination.

                (a) Termination of Agreement. The Parties may terminate this
Agreement as provided below:

                        (i) the Buyer and the Seller Representatives may
                terminate this Agreement by mutual written consent at any time
                prior to the Closing;

                        (ii) the Buyer may terminate this Agreement by giving
                written notice to the Seller Representatives at any time prior
                to the Closing (A) in the event any of the Sellers has breached
                any representation, warranty, or covenant contained in this
                Agreement in any material respect, the Buyer has notified the
                Seller Representatives of the breach, and the breach has
                continued without cure for a period of 10 days after the notice
                of breach or (B) if the Closing shall not have occurred on or
                before January 15, 2002, by reason of the failure of any
                condition precedent under Section 7(a) hereof (unless the
                failure results primarily from the Buyer itself breaching any
                representation, warranty, or covenant contained in this
                Agreement); and

                        (iii) the Seller Representatives may terminate this
                Agreement by giving written notice to the Buyer at any time
                prior to the Closing (A) in the event the Buyer has breached any
                representation, warranty, or covenant contained in this
                Agreement in any material respect, the Seller Representatives
                have notified the Buyer of the breach, and the breach has
                continued without cure for a period of 10 days after the notice
                of breach or (B) if the Closing shall not have occurred on or
                before January 15, 2002, by reason of the failure of any
                condition precedent under Section 7(b) hereof (unless the
                failure results primarily from any of the Sellers themselves
                breaching any representation, warranty, or covenant contained in
                this Agreement).


                                      -41-
<PAGE>

                (b) Effect of Termination. If any Party terminates this
Agreement pursuant to Section 11(a) above, all rights and obligations, except
any rights and obligations related to Confidential Information, of the Parties
hereunder shall terminate without any Liability of any Party to any other Party
(except for any Liability of any Party then in breach).

        12. Miscellaneous.

                (a) Nature of Certain Obligations.

                        (i) The covenants of each of the Sellers in Section 2(a)
                above concerning the sale of his Class A Units to the Buyer and
                the representations and warranties of each of the Sellers in
                Section 3(a) above concerning the transaction are several
                obligations. This means that the particular Seller making the
                representation, warranty, or covenant will be solely responsible
                to the extent provided in Section 8 above for any Adverse
                Consequences the Buyer may suffer as a result of any breach
                thereof.

                        (ii) The remainder of the representations, warranties,
                and covenants in this Agreement are joint and several
                obligations. This means that each Seller will be responsible to
                the extent provided in Section 8 above for the entirety of any
                Adverse Consequences the Buyer may suffer as a result of any
                breach thereof.

                (b) Legend. All share certificates representing shares of Buyer
Common Stock delivered to the Sellers hereunder shall bear a legend
substantially as follows:

                THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                "SECURITIES ACT") OR QUALIFIED UNDER ANY APPLICABLE STATE
                SECURITIES LAWS (THE "STATE ACTS"), HAVE BEEN ACQUIRED FOR
                INVESTMENT AND MAY NOT BE SOLD, PLEDGED, HYPOTHECATED OR
                OTHERWISE TRANSFERRED EXCEPT PURSUANT TO A REGISTRATION
                STATEMENT UNDER THE SECURITIES ACT AND QUALIFICATION UNDER THE
                STATE ACTS OR EXEMPTIONS FROM SUCH REGISTRATION OR QUALIFICATION
                REQUIREMENTS (INCLUDING, IN THE CASE OF THE SECURITIES ACT, THE
                EXEMPTION AFFORDED BY RULE 144).

                (c) Press Releases and Public Announcements. No Party shall
issue any press release or make any public announcement relating to the subject
matter of this Agreement without the prior written approval of the Buyer and the
Seller Representatives; provided, however, that any Party may make any public
disclosure it believes in good faith is required by applicable law or any
listing or trading agreement concerning its publicly-traded securities (in which
case the disclosing Party will use its commercially reasonable efforts to advise
the other Parties prior to making the disclosure).

                (f) Succession and Assignment. This Agreement shall be binding
upon and inure to the benefit of the Parties named herein and their respective
successors and permitted assigns. No Party may assign either this Agreement or
any of his rights, interests, or obligations hereunder without the prior written
approval of the Buyer and the Seller Representatives; provided, however, that
the Buyer may (i) assign any or all of its rights and interests hereunder to one
or more of its Affiliates and (ii) designate one or more of its Affiliates to
perform its obligations hereunder (in any or all of which cases the Buyer
nonetheless shall remain responsible for the performance of all of its
obligations hereunder).

                (g) Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

                (h) Headings. The section headings contained in this Agreement
are inserted for convenience only and shall not affect in any way the meaning or

                (j) Governing Law. This Agreement shall be governed by and
construed in accordance with the domestic laws of the State of California
without giving effect to any choice or conflict of law provision or rule

California.

                (k) Amendments and Waivers. No amendment or waiver of any
provision of this Agreement shall be valid unless the same shall be in writing

<PAGE>

                (l) Severability. Any term or provision of this Agreement that
is invalid or unenforceable in any situation in any jurisdiction shall not
affect the validity or enforceability of the remaining terms and provisions
hereof or the validity or enforceability of the offending term or provision in
any other situation or in any other jurisdiction.

                (m) Expenses. Each of the Parties will bear his or its own costs
and expenses (including legal fees and expenses) incurred in connection with
this Agreement and the transactions contemplated hereby. The Sellers agree that
the Target has not borne and will not bear any of the Sellers' costs and
expenses (including any of their investment advisor fees, legal fees and
expenses) in connection with this Agreement or any of the transactions
contemplated hereby.

                (n) Termination of the Voting Trust Agreement. Each of the
Sellers who are a party to that certain Voting Trust Agreement dated as of March
27, 2000 hereby agrees that such Voting Trust Agreement shall be terminated as
of the Closing Date.

                (o) Construction. The Parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise favoring or disfavoring any Party by virtue of the authorship of any of
the provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean including without limitation. The Parties intend
that each representation, warranty, and covenant contained herein shall have
independent significance. If any Party has breached any representation,
warranty, or covenant contained herein in any respect, the fact that there
exists another representation, warranty, or covenant relating to the same
subject matter (regardless of the relative levels of specificity) that the Party
has not breached shall not detract from or mitigate the fact that the Party is
in breach of the first representation, warranty, or covenant.

                (p) Incorporation of Exhibits, Annexes, and Schedules. The
Exhibits, Annexes, and Schedules identified in this Agreement are incorporated
herein by reference and made a part hereof.

                (q) Specific Performance. Each of the Parties acknowledges and
agrees that the other Parties would be damaged irreparably in the event any of
the provisions of this Agreement are not performed in accordance with their
specific terms or otherwise are breached. Accordingly, each of the Parties
agrees that the other Parties shall be entitled to an injunction or injunctions
to prevent breaches of the provisions of this Agreement and to enforce
specifically this Agreement and the terms and provisions hereof in any action
instituted in any court of the United States or any state thereof having
jurisdiction over the Parties and the matter (subject to the provisions set
forth in Section 12(r) below), in addition to any other remedy to which they may
be entitled, at law or in equity.

                (r) Mediation/Arbitration. If a dispute arises out of or relates

Representatives shall negotiate in good faith to settle such dispute,
controversy or claim within fifteen (15) calendar days of notice

thereof. If the Buyer and the Seller Representatives are unable to resolve such
dispute, controversy or claim arising out of this Agreement or the performance,
breach or termination thereof within fifteen (15) calendar days, it shall be
settled by arbitration in accordance with the Commercial Arbitration Rules of
the American Arbitration Association. The place of arbitration shall be San
Diego, California. The arbitration shall be conducted by a neutral arbitrator
selected by mutual agreement of the Buyer and the Seller Representatives within
ten days after notice by either party to the other requesting such arbitration.
If the Buyer and the Seller Representatives fail to agree within ten days on the
selection of the arbitrator, an arbitrator shall be promptly appointed by the
American Arbitration Association. Prior to issuing a final arbitration award,
the arbitrator shall provide the Buyer and the Seller Representatives with a
preliminary ruling and allow the Buyer and the Seller Representatives a
reasonable period (not to exceed five (5) business days) to respond in writing
to the preliminary ruling. Judgment upon the arbitration award rendered may be
entered in any court having jurisdiction. The prevailing party shall be entitled
to all costs of arbitration including, but not limited to, reasonable attorneys'
fees and out-of-pocket expenses. The Parties further agree that they shall be
entitled to discovery in the same manner as though the dispute were within the
jurisdiction of the Superior Court of the State of California. Except as
otherwise required by law (or by the fiduciary duties of the Buyer's directors),
all information resulting from or otherwise pertaining to any dispute shall be
nonpublic and handled by the Buyer, the Seller and their respective agents in
such a way as to prevent the public disclosure of such information.
