the separate existence of Merger Sub (except as such existence may be continued by operation of
law) shall cease, and Xicom shall continue as the surviving corporation under the corporate name 2

it possesses immediately prior to the Effective Time. Xicom, in its capacity as the
corporation surviving the Merger, sometimes is referred to herein as the Surviving
Corporation. 1.2 Effect of the Merger. The Surviving Corporation shall possess all the rights,
privileges, immunities and franchises, of a public as well as of a private nature, of each of
Merger Sub and Xicom (collectively, the Constituent Corporations); all property, real,
personal and mixed, and all accounts payable arising in the ordinary course of business and accrued
expenses due on whatever account, and all debts, liabilities and duties due to each of the
Constituent Corporations shall be transferred to and vested in the Surviving Corporation without
further act or deed; and the Surviving Corporation shall be responsible and liable for all
liabilities and obligations of each of the Constituent Corporations, in each case in accordance
with California Law, but subject, as between the parties, to the provisions below. 1.3 Consummation of the Merger. As soon as is practicable after the satisfaction or
waiver of the conditions set forth in Article 7, and in no event later than five business
days after such satisfaction or waiver, the parties hereto will cause an agreement of merger (the
Agreement of Merger), along with certificates of approval of the Agreement of Merger, to
be filed with the Secretary of State of the State of California in accordance with California Law.
The Merger shall be effective at such time as the Agreement of Merger is duly filed. The date and
time when the Merger shall become effective is referred to as the Effective Time. 1.4 Articles of Incorporation and Bylaws; Directors and Officers. The Articles of
Incorporation of the Surviving Corporation, as in effect immediately prior to the Effective Time,
shall be amended and restated to read the same as the Articles of Incorporation of Merger Sub as in
effect immediately prior to the Effective Time, except that Section 1 of the amended and restated
Articles of Incorporation of the Surviving Corporation, instead of reading the same as Section 1 of
the Articles of Incorporation of Merger Sub, shall read as follows: The name of this corporation
is Xicom Technology Inc. The Bylaws of Xicom as the Surviving Corporation shall be amended to
read the same as the Bylaws of Merger Sub as in effect immediately prior to the Effective Time,
except that all references to Merger Sub in the Bylaws of the Surviving Corporation shall be
changed to refer to Xicom Technology Inc. The directors of Merger Sub holding office immediately
prior to the Effective Time shall be the directors of the Surviving Corporation immediately after
the Effective Time, together with Walter C. Wood. The officers of Xicom holding office immediately
prior to the Effective Time shall be the officers (holding the same offices as they held with
Xicom) of the Surviving Corporation immediately after the Effective Time, except that Robert C.
Fitting shall become the Chairman of the Board of the Surviving Corporation and Malcolm C. Persen
shall become the Secretary of the Surviving Corporation. 1.5 Conversion of Securities. At the Effective Time, by virtue of the Merger and
without any action on the part of Merger Sub, Xicom or the holders of any of the following
securities: (a) Each share of common stock, no par value per share, of Xicom (the Xicom Common
Stock) issued and outstanding immediately prior to the Effective Time shall automatically be
canceled and extinguished and converted into and become a right to receive an 3

##### 



amount equal to the Merger Consideration divided by the number of shares of Xicom Common Stock
outstanding as of the Effective Time. The Merger Consideration, in the aggregate, means (i) $39,028,700 in cash (the Cash
Consideration), subject to adjustment as set forth in Section 1.6, plus (ii) the
number of shares of Radyne Common Stock equal to (A) $2,000,000 divided by (B) the Share Closing
Price (the Merger Shares). The Share Closing Price shall be equal to the average reported closing price for Radyne
Common Stock on the Nasdaq National Market as reflected in the Western Edition of the Wall Street
Journal starting 20 trading days prior to and ending on the date of this Agreement. (b) The Merger Shares shall be adjusted to reflect fully the effect of any stock split,
reverse split, stock dividend (including any dividend or distribution of securities convertible
into Radyne Common Stock), reorganization, recapitalization or other like change with respect to
Radyne Common Stock occurring after the date hereof and prior to the Effective Time. (c) No fraction of a share of Radyne Common Stock will be issued, but in lieu thereof each
holder of shares of Xicom Common Stock who would otherwise be entitled to a fraction of a share of
Radyne Common Stock (after aggregating all fractional shares of Radyne Common Stock to be received
by such holder) shall receive from Radyne an amount of cash (rounded to the nearest whole cent)
equal to the product of (i) such fraction, multiplied by (ii) the Share Closing Price. (d) Each share of Xicom Common Stock issued and outstanding immediately prior to the Effective
Time and held in the treasury of Xicom shall automatically be canceled and extinguished and no
payment shall be made with respect thereto. (e) Each share of common stock, par value $.001 per share, of Merger Sub issued and
outstanding immediately prior to the Effective Time shall automatically be converted into and
become one validly issued, fully paid and nonassessable share of common stock, par value $.001 per
share, of the Surviving Corporation. 1.6 Adjustments to the Merger Consideration. (a) The Merger Consideration shall be increased or decreased by the sum of the following: (i) Increased or decreased, as the case may be, by the amount by which the net working capital
(total current assets less total current liabilities) less long term debt (Net Working
Capital) reflected on the Final Closing Balance Sheet (defined below) is greater or less than
$5,701,855, as calculated consistent with the calculations reflected in the Computation of Net
Working Capital attached hereto as Appendix II; (ii) Decreased by the amount of any bonus payments and related payroll taxes to be paid to
employees of Xicom as set forth on Schedule 1.6(a)(ii); and 4

##### 



(iii) Decreased by the amount of costs and expenses incurred by Xicom or the Xicom
Shareholders in connection with the preparation of this Agreement and the Merger, but only to the
extent that such amounts are accounted for in the Final Closing Balance Sheet (without
duplication). (b) Any adjustment shall be made to the Cash Consideration. (c) For the purpose of making an initial determination of Net Working Capital, Xicom will
deliver to Radyne by April 11, 2005, a balance sheet as of April 2, 2005, prepared on a basis
consistent with the October Balance Sheet (as defined in Section 3.5), and in accordance
with generally accepted accounting principles (GAAP) (the Preliminary Closing
Balance Sheet). (d) Within 75 days from the date the Preliminary Closing Balance Sheet is delivered to Radyne
(subject to extension as provided in Section 5.1(i)), Radyne will deliver to Xicom a
balance sheet reflecting its determination of actual balances for Xicom as of April 2, 2005,
prepared on a basis consistent with the October Balance Sheet and the Preliminary Closing Balance
Sheet, in accordance with GAAP and SEC Regulation S-X, and audited or reviewed (at Radynes
election) by Radynes independent public accounting firm (the Final Closing Balance
Sheet), together with a calculation of Net Working Capital and the final Merger Consideration. (e) The Final Closing Balance Sheet will become final and binding on the parties, absent
fraud, mistake or concealment, unless within five business days following delivery thereof to
Xicom, Xicom notifies Radyne in writing that Xicom objects to it. If Xicom does not object to the
Final Closing Balance Sheet, the parties shall promptly (within five business days) consummate the
Merger. (f) If Xicom does object to the Final Closing Balance Sheet, and the difference between (i)
the Net Working Capital disclosed on the Final Balance Sheet and (ii) the Net Working Capital set
forth on the Preliminary Closing Balance Sheet, is an amount that is less than or equal to
$500,000, then the parties shall consummate the Merger within five business days, and the amount in
dispute shall be subject to arbitration in the manner set forth in Section 1.6(h) below. (g) If Xicom does object to the Final Closing Balance Sheet, and the difference between (i)
the Net Working Capital disclosed on the Final Balance Sheet and (ii) the Net Working Capital set
forth on the Preliminary Closing Balance Sheet, is an amount that is greater than $500,000, then
(A) the parties may mutually agree to consummate the Merger within five business days, and the
amount in dispute shall be subject to arbitration in the manner set forth in Section 1.6(h)
below, or (B) either party may, by written notice within five business days of the delivery of the
Final Closing Balance Sheet, terminate this Agreement, in which event the cost of the audit thereof
shall be borne by Xicom (and all other expenses incurred by Xicom in accordance with Section
6.1). (h) Any dispute under this Section 1.6 shall be submitted to an independent accounting
firm of national reputation mutually acceptable to the Shareholders Representative and Radyne
(other than the firm then currently serving as auditors for Radyne or Xicom) (the 5

Independent Accountant). If the Shareholders Representative and Radyne are unable
to agree on the Independent Accountant, then, within 45 days following the delivery of the Final
Closing Balance Sheet to the Shareholders Representative, the Shareholders Representative and
Radyne shall request the American Arbitration Association (AAA) to appoint the
Independent Accountant. The determination of the Independent Accountant will be final and binding
on all parties, and judgment on the determination may be enforced in any court having jurisdiction.
If the results of the arbitration indicate that the amount of Net Working Capital set forth in the
Final Closing Balance Sheet was understated by the greater of $100,000 or 10% of the difference
between Net Working Capital disclosed in the Final Closing Balance Sheet and the amount determined
by the Independent Accountant, then the expenses of such arbitration shall be paid entirely by
Raydne. If the results of the arbitration indicate that the amount of Net Working Capital set
forth in the Preliminary Closing Balance Sheet was overstated by the greater of $100,000 or 10% of
the difference between Net Working Capital disclosed in the Preliminary Closing Balance Sheet and
the amount determined by the Independent Accountant, then the expenses of such arbitration shall be
paid entirely by the Shareholders. In all other cases, the expenses of the arbitration shall be
shared by the parties, and each will bear its own attorneys fees and costs. Upon determination of
the Final Closing Balance Sheet pursuant to this Section 1.6, Radyne will pay the Xicom
Shareholders any additional payment required by Section 1.5(a) or, if payment is due to
Radyne pursuant hereto, Radyne and the Shareholders Representative will instruct the escrow agent
pursuant to the Escrow Agreement (as defined in Section 1.7) to release such funds to
Radyne. 1.7 Escrow. (a) At Closing, Radyne, the Shareholders, the Shareholders Representative and an escrow
agent, to be chosen by mutual agreement of the Radyne and the Shareholders Representative, shall
enter into an escrow agreement in substantially the form attached hereto as Exhibit A (the
Escrow Agreement). The escrow agent will hold [ * ] (the Escrow Amount) in
escrow (the Escrow Fund) as security to cover potential losses or other claims for which
Radyne is entitled to indemnification or recovery pursuant to Article 8, and for
adjustments to the Merger Consideration in accordance with Section 1.6 above. Subject to
any claims made by Radyne, the Escrow Amount will be released to the Xicom Shareholders on the
second anniversary of the Closing. (b) The parties hereto hereby acknowledge and agree that the Escrow Amount is intended to be
treated as an installment obligation for purposes of Section 453 of the Code and, unless
required by applicable law, no party shall take any action or filing position inconsistent with
such characterization. The parties hereto further agree that, subject to any future Treasury
Regulations or other changes in the law, pursuant to Proposed Treasury Regulation Section 1.468B-8,
for tax reporting purposes, all items of income, deduction and credit relating to the Escrow Amount
or any portion thereof in any tax year shall be reported as allocated to Radyne with respect to all
periods on or prior to the date that the distribution of the Escrow Amount (or portion thereof) is
determined, and with respect to all periods thereafter to Radyne and the Xicom Shareholders in
accordance with their respective interests in the   *   Confidential information on this page has been omitted

Confidential Treatment Request. 6

consideration for tax purposes (to the extent not treated as imputed interest). 1.8 Effectiveness and Closing. (a) The parties acknowledge that Xicom has not delivered complete disclosure schedules, as
contemplated in Article 3, nor has Radyne interviewed employees or third parties (such as
customers, suppliers, dealers, sales representatives, lenders and lessors). Xicom agrees that (i)
within five business days of the date hereof (the Due Diligence Delivery Date), it will
provide complete disclosure schedules, together with all underlying documentation or information to
Radyne and (ii) it will provide access to its employees and third parties for the purpose of Radyne
completing interviews thereof. (b) This Agreement will become effective only if Radyne provides the notice set forth in
subsection (c) below (the Effectiveness Notice), which it must deliver, if at
all, within five business days of the Due Diligence Delivery Date. (c) If issued, the Effectiveness Notice shall provide as follows: To:   Walter C. Wood, CEO of Xicom Technology Inc.
From: Robert C. Fitting, CEO of Radyne ComStream Inc. By signing below, Radyne confirms that it has completed its review of the
disclosure schedules provided by Xicom to Radyne and Merger Sub, and the
underlying documentation and information set forth on such disclosure

and the agreements delivered hereunder. (d) If the Effectiveness Notice is not provided within the time set forth in subsection

Merger as promptly as possible. If, at any time after the Effective Time, any further action is
necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving
Corporation with full possession of all the rights, privileges, immunities and franchises of the
Constituent Corporations, or fully subject the Surviving Corporation to all debts and obligations

thereof may be limited by bankruptcy, insolvency, reorganization or other similar laws relating to

nor Merger Sub is subject to, or obligated under, any provision of (a) its Certificate of
Incorporation or its Bylaws; (b) any agreement, arrangement or understanding; (c) any license,
franchise or permit; or (d) any law, regulation, order, judgment or decree, that would be breached,

which they were made, not misleading. 2.6 Nasdaq National Market. The Radyne Common Stock is listed on the Nasdaq National

ARTICLE 8 INDEMNITIES 8.1 Survival of Representations and Warranties. All representations and warranties
made by Radyne, Merger Sub, Xicom and the Xicom Shareholders in this Agreement shall survive for [
* ] from the date of this Agreement and no claim for any breach thereof may be made unless notice
thereof is given to the other party prior to such date; provided, however, that the
limitations on survival shall not apply to any breach of this Agreement constituting fraud or
intentional misrepresentation or omission. The parties agree that reliance shall not be an element
of any claim for misrepresentation or indemnification under this Agreement. 8.2 Shareholders Agreement to Indemnify. (a) Subject to the limitations in this Article 8, the Shareholders, jointly and
severally, agree to indemnify and hold harmless Radyne and Merger Sub and their respective
directors, officers, employees and agents from and against all proceedings, judgments, decrees,
demands, claims, actions, losses, damages, liabilities, costs and expenses, including, without
limitation, reasonable attorneys fees and costs (collectively referred to as Losses)
asserted against or incurred by Radyne, Merger Sub or their respective directors, officers,
employees or agents resulting from (i) a breach of any covenant, agreement, representation or
warranty of Xicom or the Xicom Shareholders contained in this Agreement or the exhibits or
schedules hereto; (ii) any lawsuit, open tax matter, employee dispute or other similar contingency
disclosed on a schedule (or that should have been disclosed on a schedule or in the Financial
Statements) in excess of litigation, tax or related reserves; or (iii) any claim based on the
respective equity ownership of the Xicom Shareholders or the allocation of the consideration set
forth in this Agreement; provided, however, that any liability of a Shareholder for
such Shareholders breach of his non-disclosure and non-compete agreement delivered under
Section 7.3(f) shall be several and not joint. (b) For purposes of assessing indemnification for any breach of warranty, representation,
covenant or agreement, any materiality (including any Material Adverse Change) or knowledge
qualifiers shall be eliminated, except knowledge qualifiers with respect to threatened matters. (c) The Shareholders will not be obligated to indemnify Radyne or its directors, officers,
employees or agents for any Loss except to the extent that such Loss, alone or when aggregated with
all other Losses, exceeds [ * ] (the Indemnity Basket), unless such Loss results from the
matters referenced in subsections (a)(ii) or (a)(iii) above, in which case the
Shareholders will be responsible for all Losses. (d) Further, the Shareholders shall not be obligated to indemnify Radyne and its directors,
officers, employees and agents to the extent that any Loss, alone or when   *      Confidential information on this page has been omitted

##### 



aggregated with all other Losses, exceeds [ * ] (the Indemnity Ceiling), and
Radynes sole remedy for damages (except as provided in subsection (e) below) shall be
limited to [ * ]. (e) The Indemnity
Basket, the Indemnity Ceiling and the limitation on seeking damages solely
from [ * ] will not apply under this Section 8.2 in the event any Loss is based
on the fraud or intentional misrepresentation or omission of Xicom or any of the Xicom
Shareholders. 8.3 Radyne and Merger Subs Agreement to Indemnify. Subject to the limitations in
this Article 8, Radyne and Merger Sub hereby agree to indemnify and hold harmless the Xicom
Shareholders and their agents from and against all Losses asserted against or incurred by the Xicom
Shareholders or their agents resulting from a breach of any covenant, agreement, representation or
warranty of Radyne or Merger Sub contained in this Agreement or the exhibits hereto. Radyne will
not be obligated to indemnify the Xicom Shareholders or any of their agents for any Loss except to
the extent that such Loss, alone or when aggregated with other Losses, exceeds the Indemnity
Basket. Further, Radyne shall not be obligated to indemnify the Xicom Shareholders or any of their
agents to the extent that any Loss, alone or when aggregated with other Losses, exceeds the
Indemnity Ceiling. Neither the Indemnity Basket nor the Indemnity Ceiling will apply under this
Section 8.3 in the event any Loss is based on the fraud or intentional misrepresentation or
omission of Radyne or Merger Sub. Xicom and the Xicom Shareholders agree that any claim for
indemnification against Radyne or Merger Sub under this Article 8 shall be made solely
through the Shareholders Representative, and that any and all actions with respect to the rights
of the Xicom Shareholders under this Article 8 and the Escrow Agreement shall be exercised
solely through the Shareholders Representative. 8.4 Notice of Claim. Any party who has a claim which would give rise to liability
pursuant to this Article 8 shall give prompt notice to all other parties of such claim,
together with a reasonable description thereof; provided, that Radyne and Merger Sub shall
provide such notice only to the Shareholders Representative. With respect to any claim by a third
party which is covered by the indemnifications contained hereunder, the party obligated to
indemnify shall be afforded the opportunity, at its expense, to defend or settle such claim if,
within 10 days of notice thereof, it acknowledges in writing its indemnification obligation
hereunder, utilizes counsel reasonably satisfactory to the indemnified party, commences such
defense promptly and pursues such defense with diligence; provided, however, that
such indemnifying party shall secure the consent of the indemnified party to any settlement, which
consent shall not be unreasonably withheld, unless the amount of the settlement (together with
other settlements) is below the Indemnity Basket. If an indemnified party defends any claim
hereunder, such party shall use reasonable efforts in such defense to mitigate Losses arising
thereunder, and shall not settle any claim without the consent of the indemnifying party, which
shall not be unreasonably withheld; provided, that any consent by the Shareholders
Representative shall constitute adequate consent on behalf of any Xicom Shareholder under this
Section 8.4. Notwithstanding the foregoing, (i) if a claim seeks relief other than the
payment of monetary damages; (ii) if the subject matter of a claim relates to the ongoing business
of the indemnified party (including with   *    Confidential information on this page has been omitted

Confidential Treatment Request. 29

##### 



out limitation, any relationship with continuing suppliers, customers or other persons or
entities with whom the indemnified party does business), which claim, if decided against the
indemnified party, could materially adversely affect the ongoing business or reputation of the
indemnified party or its relationship to such other party; or (iii) the indemnified party may not
be fully indemnified with respect to such claim, then, in each such case, the indemnified party
alone shall be entitled to contest, defend and settle such claim in the first instance and, if the
indemnified party does not contest, defend or settle such claim, the indemnifying party shall then
have the right to contest and defend such claim, but not settle such claim without the consent of
the indemnified party, which consent will not be unreasonably withheld. 8.5 Satisfaction of Obligations. If an indemnifying party becomes obligated to
indemnify another party with respect to any claim for indemnification hereunder and the amount of
liability with respect thereto shall have been finally determined, the indemnified party, and in
the event the indemnified party is a Xicom Shareholder, the Shareholders Representative, shall
deliver a notice to the indemnifying party and the escrow agent demanding payment pursuant to the
Escrow Agreement. Additional provisions regarding the procedures for indemnification are as set
forth in the Escrow Agreement. 8.6 Exclusive Remedy. The rights and remedies provided for in this Agreement shall be
exclusive and no other rights and remedies that may exist at law may be asserted against any party;
provided, however, that the foregoing will not limit the right of Radyne or Merger
Sub to pursue equitable remedies, including equitable remedies related to the enforcement of any
non-compete agreement described under Section 7.3(f), nor in the case of fraud or
intentional misrepresentation or omission. ARTICLE 9 TERMINATION, AMENDMENT AND WAIVER 9.1 Termination. This Agreement may be terminated at any time prior to the Effective
Time: (a) by mutual consent of a duly authorized officer of Radyne and Xicom and the Shareholders
Representative; (b) by Radyne or Merger Sub, on the one hand, or Xicom, on the other hand, if the other party
breaches any of its material representations, warranties or covenants contained herein and, if such
breach is curable, is not cured within 15 business days after notice thereof; (c) by Radyne or Merger Sub, on the one hand, or Xicom, on the other hand, if obligations to
close the transactions contemplated by this Agreement shall become incapable of satisfaction; (d) by Radyne or Merger Sub, on the one hand, or Xicom, on the other hand, if the Merger shall
not have been consummated by May 31, 2005 or such later date as may be agreed upon by Radyne,
Merger Sub and the Shareholders Representative; provided, however, that the right
to terminate this Agreement under this Section 9(d) shall not be available to any 30

##### 



party whose failure to fulfill any obligation under this Agreement has been the cause of, or
resulted in, the failure of the Effective time to occur on or before May 31, 2005; or (e) as provided in Sections 1.6 or 1.8. 9.2 Effect of Termination. In the event of termination of this Agreement as provided
in Section 9.1, this Agreement shall become void and there shall be no liability or further
obligation hereunder on the part of the parties or their respective securityholders, officers or
directors, except as set forth in Sections 1.6, 1.8, 6.1 and 6.3,
and except for liability arising from a willful breach of this Agreement. 9.3 Amendment. This Agreement may not be amended except by an instrument in writing
approved by Radyne, Merger Sub and Xicom. 9.4 Waiver. At any time prior to the Effective Time, Radyne or Merger Sub may extend
the time for the performance of any of the obligations or other acts of any other party hereto and
Xicom may extend the time for performance of any of the obligations of Radyne or Merger Sub. In
addition, Radyne and Merger Sub, on the one hand, and Xicom, on the other hand, may waive
compliance with any of the agreements of any other party or with any conditions to its own
obligations, in each case only to the extent such obligations, agreements and conditions are
intended for its benefit. ARTICLE 10 TAX MATTERS The following provisions shall govern the allocation of responsibility as between Radyne and
the Shareholders for certain tax matters following the Effective Time: 10.1 Responsibility for Filing Tax Returns. Radyne shall prepare or cause to be
prepared and file or cause to be filed all Tax Returns for Xicom that are required to be filed
after the Effective Time. 10.2 Cooperation on Tax Matters. Radyne, Xicom and the Shareholders (through the
Shareholders Representative) 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 Article 10
and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall
include the retention and (upon the other partys 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. 10.3 Control of Tax Proceedings. If any claim, suit or proceeding shall be made by
any taxing authority that could give rise to an additional payment of Taxes, the party responsible
for the payment of such Taxes shall control all proceedings arising in connection with such claim,
suit or proceeding; provided, however, that if the subject matter of a claim, suit
or proceeding relates to the ongoing business of Xicom (including without limitation, its 31

employees, suppliers, customers or other persons or entities with whom Xicom does business),
which claim, suit or proceeding, if decided against the Xicom, could materially adversely affect
the ongoing business or reputation of Xicom or its relationship with such party after the Effective
Time, then Radyne or Xicom, at their election, shall be entitled to contest, defend and settle such
claim, suit or proceeding. For purposes of the foregoing, the Shareholders Representative shall
be deemed the party responsible for any Taxes the payment of which would result in a claim against
[*]. ARTICLE 11 GENERAL PROVISIONS 11.1 Public Statements. Except as required by applicable law, rule or regulation,
including of the Nasdaq National Market, prior to the Effective Time, no party shall make any
public announcement or statement with respect to the Merger, this Agreement or any related

disputes and other matters in controversy (herein called a Dispute) arising directly or
indirectly out of or related to this Agreement, or the breach thereof, whether contractual or
noncontractual, and whether during the term or after the termination of this Agreement, will be
resolved exclusively according to the procedures set forth in this Section 11.3. (a) Negotiation. The parties will attempt to settle Disputes arising out of or
relating to this Agreement, or the breach thereof, by a meeting of two designated representatives
of each party within five days after a request by either of the parties to the other party asking
for the same. (b) Mediation. If such Dispute cannot be settled at such meeting, either party within
five days of such meeting may give a written notice (a Dispute Notice) to the other party
setting forth the nature of the Dispute. The parties will attempt in good faith to resolve the
Dispute by mediation in Phoenix, Arizona under the Commercial Mediation Rules of AAA in effect on
the date of the Dispute Notice. The parties will select a person who will act as the mediator
under this subsection (b) within 60 days of the date of this Agreement. If the Dispute has
not been resolved by mediation as provided above within 30 days after delivery of the Dispute
Notice, then the Dispute will be determined by arbitration in accordance with the provisions of
subsection (c) below. (c) Arbitration. Any Dispute that is not settled through mediation as provided in
subsection (b) above will be resolved by arbitration in Phoenix, Arizona, governed by the
Federal Arbitration Act, 9 U.S.C. § 1 et seq., and administered by the AAA under its Commercial
Arbitration Rules in effect on the date of the Dispute Notice, as modified by the provisions of
this subsection (c), by a single arbitrator. The arbitrator selected, in order to be
eligible to serve, will be a lawyer with at least 15 years experience specializing in business
matters. In the event the parties cannot agree on a mutually acceptable single arbitrator from the
list submitted by the AAA, AAA will appoint the arbitrator who will meet the foregoing criteria.
The arbitrator will base the award on applicable law and judicial precedent and, unless both
parties agree otherwise, will include in such award the findings of fact and conclusions of law
upon which the award is based. Judgment on the award rendered by the arbitrator may be entered in
any court having jurisdiction thereof. 33

##### 



(d) Notwithstanding the foregoing or anything in this Agreement to the contrary: (i) Upon the application by either party to a court for an order confirming, modifying or
vacating the award, the court will have the power to review whether, as a matter of law based on
the findings of fact determined by the arbitrator, the award should be confirmed, modified or
vacated in order to correct any errors of law made by the arbitrator. In order to effectuate such
judicial review limited to issues of law, the parties agree (and will stipulate to the court) that
the findings of fact made by the arbitrator will be final and binding on the parties and will serve
as the facts to be submitted to and relied on by the court in determining the extent to which the
award should be confirmed, modified or vacated; and (ii) Either party will have the right to apply to any court for an order to specifically
enforce their rights under this Agreement and the other agreements contemplated by this Agreement,
including but not limited to a partys obligation to close the transaction and the confidentiality
provisions contained in this Agreement. (e) Costs and Attorneys Fees. If either party fails to proceed with mediation or
arbitration as provided herein or unsuccessfully seeks to stay such mediation or arbitration, or
fails to comply with any arbitration award, or is unsuccessful in vacating or modifying the award
pursuant to a petition or application for judicial review, the other party will be entitled to be
awarded costs, including reasonable attorneys fees, paid or incurred by such other party in
successfully compelling such arbitration or defending against the attempt to stay, vacate or modify
such arbitration award and/or successfully defending or enforcing the award. (f) Tolling of Statute of Limitations. All applicable statutes of limitations and
defenses based upon the passage of time will be tolled while the procedures specified in this
