     their reasonableness in any proceeding to enforce such covenants and
     agreements. You further agree that any violation or breach by you and/or
     your representatives of this Agreement would cause immediate and
     irreparable harm to Intira, the exact amount of which will be impossible to
     ascertain, and for that reason further agrees that Intira shall be
     entitled, as a matter of right, to an injunction out of any court of
     competent jurisdiction, restraining any further violation or breach of this
     Agreement, such right to an injunction being cumulative and in addition to
     whatever remedies Intira may have under applicable law and/or this
     Agreement. You further agree to reimburse Intira for all costs and
     expenses, including attorneys' fees, incurred by Intira in enforcing the

12.  Your execution and performance of this Agreement is not restricted or
     prohibited by any agreement to which you are subject.

13.  If the scope of any provision contained in this Agreement is deemed too
     broad to permit enforcement of such provision to its full extent, then such
     provision shall be enforced to the maximum extent permitted by law, and you
     hereby consent that such provision may be reformed or modified accordingly,
     and enforced as reformed or modified.

14.  This Agreement shall be construed and enforced in accordance with the laws
     of the State of Missouri, and the Parties hereby irrevocably and
     unequivocally consent to the jurisdiction of the court sitting in the
     County of St. Louis, State of Missouri, and waive any defense of an
     inconvenient forum to the maintenance of any action or proceeding brought
     in such court in connection with this Agreement, any objection to venue
     with respect to any such action, and any right of jurisdiction on account
     of the place of residence or domicile of any party to such action.

15.  If any provision or part thereof of this Agreement is declared invalid,
     illegal or unenforceable in any respect, the validity, legality or
     enforceability of the remaining provisions of this Agreement, and any other
     application thereof, shall not in any way be affected or impaired, and the
     Agreement shall be construed in all respects as if such invalid, illegal or
     unenforceable provisions are omitted.

16.  This writing contains the agreement of the parties with respect to the
     employment contemplated herein. No amendments or variations of the terms or
     conditions of this Agreement shall be valid unless in writing and signed by
     the parties hereto.

17.  The waiver by either Party of a breach or violation of any provisions of
     this Agreement shall not operate as or be construed to be a waiver of any
     subsequent breach hereof.

18.  This Agreement shall inure to the benefit of and be binding upon the
     Parties hereto, their successors and assigns.

     $400,000.00  Pleasanton, California

                                                                  March 14, 2000

     1.   FOR VALUE RECEIVED, the undersigned, David S. Boone ("Maker"), hereby
promises to pay to Intira Corporation, a Delaware corporation ("Holder"), at
5667 Gibraltar, Pleasanton, California, or such other place as Holder may from
time to time designate by written notice to Maker, the sum of Four Hundred
Thousand Dollars ($400,000.00) together with interest on the unpaid principal
hereof from the date hereof at the rate of 0 percent (0%) per annum.  Principal
shall be due and payable on March 14, 2005.

     2.   Should Maker's employment with Holder be terminated by Holder for
Cause (as defined herein) or should Maker voluntarily resign his employment with
Holder, the whole unpaid balance on this Note of principal and interest shall
become immediately due and payable in accordance with paragraph 6 of this
Promissory Note (the "Note"). In the event that Maker's employment with Holder
is terminated by Holder without Cause within twelve (12) months of the date
hereof, 100% of this Note shall immediately be forgiven by Holder and shall
cease to be an obligation of Maker. Maker acknowledges that any forgiveness of
principal or interest will be treated by Holder as wages for withholding tax
purposes. For purposes of this Note, the term "Cause" is defined as any one or
more of the following occurrences: (a) Maker's conviction by, or entry of a plea
of guilty or nolo contendre in, a court of competent and final jurisdiction for
any crime that constitutes a felony in the jurisdiction involved; (b) Maker's
commission of an act of fraud or misappropriation of material property, whether
prior to or subsequent to the date hereof, upon Holder, or any of its respective
affiliates; (c) gross negligence by Maker in the scope of Maker's services to
Holder, or any of its respective affiliates; (d) a material breach of any
agreement, including the confidentiality or proprietary agreement between Maker
and the Holder; or (e) Maker's failure to perform the material duties of his
position after receipt of a written warning from the Holder.

     3.   This Note may be prepaid in whole or in part at any time without
penalty. All amounts payable hereunder shall be payable in lawful money of the
United States of America.

     4.   This Note is subject to the terms of a Short-Form Pledge Agreement
(the "Pledge Agreement") attached hereto as Exhibit A, and is secured by: (i) a
pledge of all shares of Common Stock of Maker whether now owned or existing or
hereafter acquired (including by exercise of any option granted to you by the
Company) (the "Collateral") and (ii) a pledge by Maker of certain real property
commonly known as 142 Victoria Place, Danville, CA (the "Property"). Maker
hereby agrees to execute and deliver to Holder a deed of trust (the "Deed of
Trust") encumbering the Property in the amount of this Note. Maker hereby
covenants that such Deed of Trust will be subordinate only to a deed of trust
(the "First Deed of Trust") made by Maker, as trustor, for the benefit of an
institutional lender that loaned money to Maker for the purpose of financing the
original purchase price of the Property.
<PAGE>

     5.   Notwithstanding anything to the contrary contained in this Note, the
entire principal balance of this Note shall become immediately due and payable,
and shall begin accruing interest, upon the occurrence of any of the following:

     (a)  The failure of Maker to execute and deliver the Deed of Trust or the
Pledge Agreement to Holder;

     (b)  The date of any sale, conveyance, assignment, alienation or any other
form of transfer of the Property or the Collateral, or any part thereof or
interest therein, whether voluntary or involuntary;

     (c)  Default in the performance or observance of any of the covenants,
conditions, provisions or agreements contained in this Note, in the Deed of
Trust, or in the Pledge Agreement;

     (d)  Default in the performance or observance of any of the covenants,
conditions, provisions or agreements contained in any deed of trust ("Senior
Deed of Trust") which is or becomes a lien against the Property senior to the
lien of the Deed of Trust, or any promissory note or obligation secured by such
Senior Deed of Trust;

     (e)  The thirtieth (30th) day following (i) the termination of Maker's
employment with Holder for Cause, or (ii) Maker's voluntary termination of
Maker's employment with Holder; or

     (f)  The fifth anniversary of the date of this Note.

     The failure of Holder to exercise any of the rights created by law or by
this Note, or to promptly enforce any of the provisions hereof, shall not
constitute a waiver of the right to exercise any such rights or to enforce any
such provisions.

     6.   Maker hereby waives demand and presentation for payment, notice of
non-payment and dishonor, protest and notice of protest, and the benefit of any
homestead exemption which may by law be waived as to this obligation, and agrees
to pay all costs and expenses incurred by Holder in connection with the
enforcement of the provisions of this Note, including, without limitation,
reasonable attorneys' fees in case of suit for enforcement or if this obligation
is placed in attorneys' hands for collection.

     7.   Maker hereby acknowledges that the Holder has made no representation
or warranty to Maker concerning the income tax consequences of the loan to
Maker, and Maker shall be solely responsible for ascertaining and bearing such
tax consequences.

                             [Company Letterhead]

                                        February 21, 2000

     Mr. David Boone
     3810 Ortega Blvd
     Jacksonville, FL 32210

     Dear David:

     This letter will confirm our agreement regarding a loan by Intira
Corporation, a Delaware corporation, (the "Company") to you in the amount of
$400,000.  As we discussed, the loan will be evidenced by a promissory note (the
"Note"), which is secured by a deed of trust to your primary residence and a
short-form pledge agreement.  You agree to execute all documents necessary to
grant the Company a security interest in (i) your primary residence and (ii) any
shares that you may purchase (including by exercise of any option granted to you
by the Company).  As we discussed, should you be terminated by the Company for
any reason other than Cause (as defined in the Note), 100% of all principal and
accrued interest shall be forgiven on the date of such termination.  However,
should you voluntarily terminate your employment with the Company or should you
be terminated for Cause, the Note would become due and payable within thirty
(30) days of either event, as set forth in the Note.  In the event there is any
inconsistency between this letter and the terms of the Note, the Note shall
control.

     If the foregoing accurately sets forth your understanding of our agreement,
please sign the enclosed copy of this letter and return it to the Company.

                                   Yours very truly,

                                   Intira Corporation

                                   By:  /s/ Bernard Schneider
                                       ---------------------------------
