(a)General.Each of the Parties shall use its best efforts to take all action and to do all things reasonably necessary, proper, or advisable in
order to consummate and

(b)Notices and Consents.SANavigator, Connex, and Western Digital shall give (and will cause each of its Subsidiaries to give) any notices to third
parties, and SANavigator, Connex and
Western Digital will each use commercially reasonable efforts to obtain (and will cause each of its Subsidiaries to use commercially reasonable efforts to obtain) any third party consents, in
connection with the matters referred to in Section 3A(c) above. The Sellers shall not enter into any consent agreement that (i) alters the terms of the related agreement or
(ii) will cause SANavigator to have any obligations other than those set forth
in the related agreement, without the written consent of the Buyer, which consent shall not be unreasonably withheld. Each of the Parties will give any notices to, make any filings with, and use
commercially reasonable efforts to obtain any authorizations, consents, and approvals of governments and governmental agencies in connection with the matters referred to in Section 3A(c) and
Section 4(c) above.

(c)Operation of Business.SANavigator shall not engage in any practice, take any action, or enter into any transaction outside the Ordinary Course of
Business except as necessary to
consummate the transactions contemplated hereby. Without limiting the generality of the foregoing, SANavigator will not (i) declare, set aside, or pay any dividend or make any distribution with
respect to its capital stock or redeem, purchase, or otherwise acquire any of its capital stock, (ii) pay any amount to any third party with respect to any Liability or obligation (including
any costs and expenses SANavigator has incurred or may incur in connection with this Agreement and the transactions contemplated hereby) which would not constitute an Assumed Liability if in existence
as of the Closing, (iii) otherwise engage in any practice, take any action, or enter into any transaction of the sort described in Section 3A(h) above, or (iv) otherwise
enter into any transaction (or maintain its business in any manner) that could be reasonably expected to materially adversely affect its business, financial condition, operations or results of
operations.

(d)Preservation of Business.SANavigator shall use commercially reasonable efforts 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.SANavigator shall permit representatives of the Buyer to have full access at all reasonable times, and in a manner so as not to
interfere with the normal
business operations of SANavigator, to all premises, properties, personnel, books, records (including Tax records), contracts, and documents of or pertaining to SANavigator. SANavigator will cooperate
with the Buyer in arranging meetings with SANavigator's employees.

(f)Notice of Developments.Each Party shall give prompt written notice to the other Party of any material adverse development constituting a breach
of any of its own representations and
warranties in Section 3 and Section 4 above. No disclosure by any Party pursuant to this Section 5(f), however shall be deemed to amend or supplement the Disclosure Schedule.

(g)Exclusivity.SANavigator shall not (i) solicit, initiate, or encourage the submission of any proposal or offer from any Person relating to
the acquisition of any
capital stock or other voting securities, or any substantial portion of the assets, of SANavigator (including any acquisition structured as a merger, consolidation, or share exchange) 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. SANavigator, Connex,

and Western Digital will notify the Buyer immediately if any Person makes any proposal, offer, inquiry, or contact with respect to any of the foregoing.

(i)Employees.The employees of SANavigator so determined by the Buyer in its sole discretion shall be offered at-will employment by Buyer, to be
effective as of
the Closing Date. Such offers of employment will provide for compensation and other benefits from the Buyer as may be determined by the Buyer in its sole discretion; provided, however, that such
compensation and other benefits will be substantially as favorable as such employees' current compensation and benefit packages from SANavigator and the salary and options granted to such employees
shall be no less than those set forth in the side letter of even date herewith. To the extent permitted by law and existing agreements with third party benefit providers, Buyer shall grant all
Continuing Employees credit for all services provided to SANavigator prior to the Closing Date (to the same extent as service with Buyer is taken into account with similarly situated employees of
Buyer) for (i) eligibility and vesting purposes under Buyer's benefit plans and (ii) purposes of vacation accrual after the Closing Date. Buyer shall provide SANavigator with a copy of
each offer letter to an employee of SANavigator at least two business days prior to any such offer being made to an employee. The Buyer agrees not terminate more than three
(3) Continuing Employees for a period sixty (60) days from the Closing Date. The foregoing sentence shall not be deemed to limit the Buyer's right to terminate any Continuing Employees
for cause. The Buyer shall promptly notify SANavigator if it becomes aware of facts that lead the Buyer to believe that the conditions contained in Section 6(a)(vi) of the Agreement will
not be satisfied.

(j)Source Code.No later than five days prior to Closing, SANavigator shall deliver three copies (each in electronic form) of the source code
to the SANavigator
Software and the related documentation to Gibson, Dunn & Crutcher LLP to be held in escrow until the earlier of (i) the Closing, at which time they shall be delivered to the Buyer in
California, and (ii) termination of this Agreement pursuant to Article 8 of this Agreement, at which time they shall be returned to SANavigator.

(k)Patent Filings.SANavigator shall use commercially reasonable efforts to: (i) prosecute all pending patent applications; and (ii) file
utility patent
applications for the invention disclosures identified in Schedule 3(m)(v) of the Disclosure Schedule prior to the dates specified therein. In no event will SANavigator submit any paper
to, or take any action before, the United States Patent or Trademark Office without first receiving Buyer's written approval, which approval will not be unreasonably withheld.

(l)Integration.Buyer acknowledges that the software integration plan referred to in the Letter of Intent dated July 11, 2001, as amended, has
been satisfactorily
completed. In the event that the asset purchase contemplated by this Agreement is not completed for any reason, Buyer shall pay SANavigator an amount of $50,000
in consideration of the development and implementation of such integration plan. This covenant shall survive the termination of this Agreement.

6.Conditions to Obligation to Close.

7.Remedies for Breaches of this Agreement.

contained in this Agreement shall survive the Closing (even if
the damaged Party knew or had reason to know of any misrepresentation or breach of warranty at the time of Closing) and continue in full force and effect for a period of 12 months thereafter;
provided, however, that the representations and warranties contained in Sections 3A(m), 3B(e) and 3C(e) of this Agreement shall survive the Closing (even if the Buyer knew or had
reason to know of any misrepresentation or breach of warranty at the time of Closing) and continue in full force and effect for a period of 18 months thereafter.

(b)Indemnification Provisions for Benefit of the Buyer.



(c)Indemnification Provisions for Benefit of SANavigator, Connex and Western Digital.



(d)Matters Involving Third Parties.







(e)Other Indemnification Provisions.The foregoing indemnification provisions are the sole and exclusive remedy any Party may have with respect to
the transactions contemplated by this Agreement;
provided, however, that the foregoing clause shall not be deemed a waiver by any party of any remedy such party may have arising out of common law fraud with respect to this Agreement.

8.Termination.

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



(b)Effect of Termination.If any Party terminates this Agreement pursuant to Section 8(a) above, all rights and obligations 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).

9.Miscellaneous.

(a)Covenant Not to Compete.For a period of two years from and after the Closing Date, neither SANavigator, Connex, Western Digital nor any of
their Subsidiaries will engage
directly or indirectly in any business that SANavigator conducts as of the Closing Date, which for purposes of this Agreement shall mean the storage area network management software business, in any
geographic area in which SANavigator or the Buyer conducts that business as of the Closing Date;provided, however, that no owner of less than 1% of the
outstanding stock of any publicly traded corporation shall be deemed to engage solely by reason thereof in any of its businesses;provided, further,
that this provision shall not be construed to prohibit SANavigator, Connex or Western Digital from being acquired by an entity that engages in the storage area network management software business.
For purposes of this paragraph the definition of storage area network shall mean a dedicated network of heterogeneous storage devices that connect to a server network through a standard interface
connection. In any such acquisition by an entity that engages in the business of SANavigator as of the Closing Date, neither the acquiror nor the acquired company (SANavigator, Connex, or Western
Digital, as the case may be) would be bound by the provisions hereof. If the final judgment of a court of competent jurisdiction declares that any term or provision of this
Section 9(a) is invalid or unenforceable, the Parties agree that the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration,
or area of the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that
comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified after the expiration of the time within which the
judgment may be appealed.

(b)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 other Party;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 best efforts to advise and cooperate with the other Party prior to making the
disclosure).

(c)No Third-Party Beneficiaries.This Agreement shall not confer any rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns.

(d)Entire Agreement.This Agreement and the Confidentiality Agreement dated June 6, 2001 (including the documents referred to herein)
constitutes the entire agreement
between the Parties and

supersedes any prior understandings, agreements, or representations by or between the Parties, written or oral, to the extent they related in any way to the subject matter hereof.

(e)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 its rights, interests, or obligations hereunder without the prior written approval of the other Party;provided,
however, that the Buyer may (i) assign any or all of its rights and interests hereunder to a wholly-owned subsidiary and (ii) designate a wholly-owned subsidiary
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) and SANavigator may assign
its rights and obligations hereunder to Connex or Western Digital.

(f)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.

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

(h)Notices.All notices, requests, demands, claims, and other communications hereunder will be in writing. Any notice, request, demand, claim, or
other communication
hereunder shall be deemed duly given if (and then two business days after) it is sent by registered or certified mail, return receipt requested, postage prepaid, and addressed to the intended

(i)Transition.None of SANavigator, Connex or Western Digital 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
SANavigator from maintaining the same business relationships with the Buyer and its Subsidiaries after the Closing as it maintained with SANavigator prior to the Closing.

(j)Confidential.After the Closing, each of SANavigator, Connex and Western Digital 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 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 which are in its possession. In the event that any of SANavigator, Connex or Western Digital 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 Party 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 9(j). If, in the absence of a protective order or the
receipt of a waiver hereunder, any of SANavigator, Connex or Western Digital is, on the advice of counsel, compelled to disclose any Confidential Information to any tribunal or else stand liable for
contempt, that Party may disclose the Confidential Information to the tribunal;provided, however, that the disclosing Party shall use its reasonable
best efforts to obtain, at the reasonable request of the Buyer, 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.

(k)Governing Law.This Agreement shall be governed by and construed in accordance with the domestic laws of the State of Delaware without giving
effect to any choice or conflict
of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

(l)Amendments and Waivers.No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by the
Buyer and SANavigator. No waiver by any
Party of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or
breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. The knowledge of a default, misrepresentation, or breach of
warranty or covenant hereunder shall not be deemed a waiver of or non-reliance on such warranty or covenant by the other Party.

(m)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.

(n)Expenses.Each of the Buyer, SANavigator, Connex and Western Digital will bear its own costs and expenses (including legal fees and expenses)
incurred in connection with
this Agreement and the transactions contemplated hereby. SANavigator also agrees that it has not paid any amount to any third party, and will not pay any amount to any third party until after the
Closing, with respect to any of the costs and expenses of SANavigator, Connex and Western Digital (including any of their legal fees and expenses) in connection with this Agreement or any of the
transactions contemplated hereby.

(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.

(p)Incorporation of Exhibits and Schedules.The Exhibits 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 Party 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 Party 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, in addition to any other remedy to which it may be entitled, at law or in equity.

(r)Submission to Jurisdiction.Each of the Parties submits to the jurisdiction of any state or federal court sitting in Denver, Colorado, in any
action or proceeding arising out of or
relating to this Agreement and agrees that all claims in respect of the action or proceeding may be heard and determined in any such court. Each of the Parties waives any defense of inconvenient forum
to the maintenance of any action or proceeding so brought and waives any bond, surety, or other security that might be required of any other Party with respect thereto. Any Party may make service on
the other Party by sending or delivering a copy of the process to the Party to be served at the address and in the manner provided for the giving of notices in Section 9(h) above.
Nothing in this Section 9(r), however, shall affect the right of any Party to bring any action or proceeding arising out of or relating to this Agreement in any other court or to serve legal
process in any other manner permitted by law or in equity. Each Party agrees that a final judgment in
any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by law or in equity.
