                             NINTH AMENDMENT TO THE
                            STERLING CHEMICALS, INC.
            AMENDED AND RESTATED HOURLY PAID EMPLOYEES' PENSION PLAN
                                  (the "Plan")

This Amendment to the Plan is adopted to comply with the automatic rollover
rules under Code Section 401(a)(31)(B). The provisions of the Amendment
applicable to the Plan if the Plan Sponsor selects Option 1 are based on the
Model Amendment provided by the Internal Revenue Service in Notice 2005-5. This
Amendment shall supersede the provisions of the Plan to the extent those
provisions are inconsistent with the provisions of this Amendment. The
provisions of this Amendment are effective with respect to distributions made on
or after March 28, 2005.

SELECTION OF COMPLIANCE METHOD
c
For purposes of complying with the requirements of Code Section 401(a)(31)(B),
the Plan Sponsor hereby elects to modify the Plan cash-out provisions to
eliminate mandatory distributions for vested Accrued Benefits with a present
value in excess of $1,000.

MODIFICATION OF CASH-OUT AMOUNT

Section 9.7 of the Plan entitled "Payment of Small Amounts" is hereby amended by
the addition of a paragraph at the end thereof to provide as follows:

      Notwithstanding any other provision of this Section, if the Actuarially
      Equivalent present value of any retirement benefit payable under the Plan
      to a Participant is greater than $1,000, such Actuarially Equivalent
      present value shall not be paid to the Participant in a single sum payment
      prior to the later of (i) the date the Participant attains age 62 or (ii)
      the Participant's Normal Retirement Date, unless the Participant consents
      in writing to such distribution. The provisions of this paragraph shall
      not apply to a distribution to a Participant's surviving spouse or an
      alternate payee under a qualified domestic relations order.

                                      * * *

Exhibit 10.1

First Amendment to

License, Distribution and Option Agreement

     This First Amendment to License, Distribution and Option Agreement (“Amendment”) is entered
into this 6th day of January, 2005 (“Amendment Effective Date”), by and between IXIA, a
California corporation doing business at 26601 West Agoura Road, Calabasas, CA 91302 (“Ixia”), and
NETIQ CORPORATION, a Delaware corporation with its principal place of business at 3553 First
Street, San Jose, California 95134, and its wholly owned subsidiaries (“NetIQ”), and amends the
License, Distribution and Option Agreement entered into on July 7, 2003, by and between Ixia and
NetIQ (the “Agreement”).

     In consideration of the premises and mutual covenants contained herein, and other valuable
consideration, the parties agree as follows:

1. Definitions

     For purposes of this Amendment, capitalized terms set forth in this Amendment shall have the
meanings set forth in the Agreement, unless otherwise defined in this Amendment.

2. Provision and Use of Customer Data

     Promptly after the Amendment Effective Date, NetIQ will provide Ixia with the Option Assets.
Ixia acknowledges and agrees that the Option Assets include information, such as customer and
customer support information, that may be protected by applicable data protection laws in certain
jurisdictions (“Protected Information”). Ixia acknowledges and agrees that such information is
provided to Ixia in order to assist it with exercising its rights as the sole, worldwide provider
of maintenance and support with respect to the Chariot Products and making support available for
the benefit of existing Chariot Product customers. Ixia agrees to comply with all applicable laws,
including data protection laws, in connection with its use and disclosure of any Protected
Information on or after the Amendment Effective Date.

3. Provision of Maintenance Services

     On or before January 7, 2005, NetIQ will (a) pay to Ixia, by wire transfer in immediately available
funds, all of NetIQ’s deferred revenues (as of January 1, 2005) related to any Distribution Product
Maintenance (the “Deferred Revenues”), and (b) provide to Ixia a detailed accounting for such
Deferred Revenues on a customer-by-customer basis (which accounting will specify the amount of
Deferred Revenues being provided to Ixia per Chariot Product, and NetIQ’s remaining Distribution
Product Maintenance period for each such Chariot Product). Separately, and within 30 days of the
Option Effective Date, NetIQ will provide Ixia with reasonable supporting documentation for the
accounting of Deferred Revenues such as customer invoices. Subject to all of the foregoing (and
NetIQ’s compliance therewith), Ixia agrees as follows: (i) Beginning on the Amendment Effective
Date, Ixia shall provide Chariot Product maintenance services (“Maintenance Services”) to those NetIQ customers who are entitled to receive
Distribution Product Maintenance from NetIQ as of the Amendment Effective Date; (ii)

-1-

 

Ixia shall provide such Maintenance Services substantially in accordance with the Ixia 12-Month Limited
Warranty and Technical Support Services Agreement attached hereto as Exhibit A; and (iii)
Ixia shall provide such Maintenance Services for the remaining term of the Distribution Product
Maintenance period to which NetIQ is obligated. Notwithstanding the foregoing, Ixia shall not be
required to provide Maintenance Services to a specific customer if the amount of Deferred Revenues
paid to Ixia pursuant to this Section 3 for that customer does not equal or exceed the greater of:
(a) the amounts actually billed (or to be billed) to such customer for any Distribution Product
Maintenance that continues beyond December 31, 2004 (which amounts shall be deemed to be eighteen
percent (18%) of the corresponding Chariot Products’ July 2003 list prices if such amounts are not
listed as separate line items on the corresponding invoice or similarly identified), and (b) fifty
percent (50%) of NetIQ’s standard July 2003 list price for such Distribution Product Maintenance
(the “Minimum Maintenance Amount”), provided that the amounts paid as Deferred Revenue shall be
prorated on a straight-line basis to reflect the portion of the Distribution Product Maintenance
term that remains after December 31, 2004. In the event the amount paid by the customer is less
than the Minimum Maintenance Amount, Ixia shall only be obligated to provide Maintenance Services
to that customer in accordance with this Amendment upon the payment by NetIQ of additional
compensation sufficient to bring the total amount paid to Ixia for that customer to the total
prorated Minimum Maintenance Amount. NetIQ represents, warrants, and covenants that, as of
December 30, 2004 and anytime thereafter, NetIQ was/is not obligated to provide any Distribution
Product Maintenance to any customer after December 31, 2006.

4. Effect of Amendment.

     Except as expressly modified herein, the terms and conditions of the Agreement shall remain in
full force and effect. This Amendment, together with the Agreement and the Schedules attached
thereto, all of which are incorporated by reference as though fully set forth in this Agreement,
constitutes the entire understanding and agreement between the parties hereto and supersedes any
and all prior or contemporaneous representations, understandings and agreements between Ixia and
NetIQ with respect to the subject matter hereof, all of which are merged herein. This Amendment
shall not be modified, amended or in any way altered except by an instrument in writing signed by
an officer of NetIQ and an officer of Ixia.

5. Counterparts.

     This Amendment may be executed in counterparts, each of which shall be deemed an original and
all of which together shall constitute one and the same instrument.

Exhibit 10.2

Second Amendment to

License, Distribution and Option Agreement

     This Second Amendment to License, Distribution and Option Agreement (“Amendment”) is entered
into this 16th day of June, 2005 (“Amendment Effective Date”), by and between IXIA, a
California corporation doing business at 26601 West Agoura Road, Calabasas, CA 91302 (“Ixia”), and
NETIQ CORPORATION, a Delaware corporation with its principal place of business at 3553 First
Street, San Jose, California 95134, and its wholly owned subsidiaries (“NetIQ”), and amends the
License, Distribution and Option Agreement entered into on July 7, 2003, by and between Ixia and
NetIQ (as previously amended, the “Agreement”).

     In consideration of the premises and mutual covenants contained herein and other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties
agree as follows:

1. Definitions

     For purposes of this Amendment, capitalized terms set forth in this Amendment shall have the
meanings set forth in the Agreement, unless otherwise defined in this Amendment.

2. Deletion of Section 22

     Section 22 of the Agreement is deleted in its entirety.

3. Assignment and Further Assurances

     NetIQ hereby sells, assigns, transfers, and sets over to Ixia (and Ixia’s successors and
assigns) the Patents set forth on Exhibit A (collectively, the “Assigned Patents”),
together with all rights and interests currently possessed by NetIQ with respect to the Assigned
Patents, including the right to sue for past infringement of the Assigned Patents and collect any
and all damages arising from such past infringement. Except as expressly set forth below in this
Section 3: (a) the Assigned Patents are assigned to Ixia, on an “AS IS, WHERE IS” basis; (b) NetIQ
makes no representations or warranties regarding the Assigned Patents, including, but not limited
to, any representation regarding ownership or validity; and (c) the representations and warranties
set forth in Section 19 of the Agreement are inapplicable to the Assigned Patents. Within five
days of the Amendment Effective Date, NetIQ shall deliver to Ixia the Memorandum of Patent
Assignment in the form attached hereto as Exhibit B. In addition, upon Ixia’s reasonable
request, NetIQ shall prepare, execute and deliver such further instruments of conveyance, sale,
assignment or transfer, at Ixia’s expense, and shall take or cause to be taken such other or
further action, as Ixia shall reasonably request of NetIQ at any time or from time to time, in
order to perfect, confirm or evidence Ixia’s title to all or any part of the Assigned Patents.

     NetIQ will provide a written conflict waiver to permit the firm of Myers Bigel Sibley &
Sajovec, P.A. and individual attorneys such as Robert W. Glatz and Mitchel S. Bigel to provide to
Ixia, at Ixia’s cost and expense, any advice, counsel, and assistance that Ixia seeks with respect
to the

 

 

Assigned Patents and/or the prosecution thereof. Promptly following Ixia’s request, NetIQ
will also provide to Ixia copies of files and other materials related to the Assigned Patents
and/or the prosecution thereof, including copies of correspondence to or from examining
authorities, invention disclosures, prior art searches, records relating to products embodying the
inventions covered by the Assigned Patents, attorney/client correspondence and internal memoranda.
Ixia will reimburse NetIQ for its out-of-pocket expenses in providing such materials.

     Promptly following Ixia’s request, and subject to its compliance with applicable laws and
regulations on data privacy, NetIQ will provide to Ixia such information it has as to the current
whereabouts of the inventors named on the Assigned Patents, and NetIQ will use commercially
reasonable efforts to encourage those inventors to cooperate with Ixia in enforcing the Assigned
Patents. If any of those inventors are NetIQ employees, NetIQ will make them available to Ixia
during normal business hours for consultation and cooperation in enforcing the Assigned Patents;
provided, however, in no event shall the burden imposed on such employees exceed ten hours per
individual and twenty hours cumulative for all such individuals unless Ixia agrees to reimburse
NetIQ for such individuals’ additional time at a reasonable per-hour rate (notwithstanding the
foregoing, the parties hereby agree that any testimony—whether in court, depositions, or
otherwise—provided by such individuals shall not count towards such time limitations, and Ixia
shall have no obligation to reimburse NetIQ or such individuals for any such testimony). In
addition, NetIQ will provide documentation, information, and other cooperation reasonably requested
by Ixia relating to the Assigned Patents and/or the prosecution thereof or to the enforcement of
the Assigned Patents. Ixia will reimburse NetIQ for its out-of-pocket expenses in providing such
cooperation.

     NetIQ hereby represents and warrants that: (i) the assignment in this Section 3 conveys to
Ixia such ownership and title in and to the Assigned Patents as it currently possesses; and (ii) to
the knowledge of NetIQ’s senior management, no licenses of or rights in the Assigned Patents (and
no immunities or covenants not to sue with respect to the Assigned Patents) have been granted to
third parties, except for licenses that pertain only to products or services developed by or for
NetIQ or distributed by or for NetIQ (and there are no agreements or commitments to grant any such
licenses, rights, immunities or covenants).

4. License of Assigned Patents

     4.1 Upon assignment of the Assigned Patents, as provided in Section 3, above, and without
limiting the generality of anything contained in this Amendment, and subject to the terms and
conditions of this Amendment, Ixia hereby grants to NetIQ, during the term of the Assigned Patents
and under Ixia’s rights to the Assigned Patents, a non-exclusive, worldwide, perpetual,
irrevocable, fully paid license, with the right to grant sublicenses as provided in Section 4.2, to
make (including the right to practice methods, processes and procedures embodied or utilized in),
have made, use, lease, sell, offer for sale and import (individually and collectively, “exploit”)
any products or services developed by or for NetIQ embodying or utilizing any invention of the
Assigned Patents (“Covered Products”), provided that the foregoing license shall not include the
right under such Assigned Patents to exploit any Test Products/Services until July 7, 2010, and
shall not include the right under such Assigned Patents to exploit any Assessment
Products/Services (except for Assessment Products/Services that are limited to the assessment
of

-2-

 

VoIP issues or security issues, and that do not expose to users or allow users to modify or edit
any of the Source Asset scripts) until June 7, 2008.

     4.2 NetIQ may sublicense its rights under Section 4.1 to (a) a successor in interest to which
NetIQ sells all or any part of a product line which includes a Covered Product, to exploit that
Covered Product (and updates thereto, to the extent those updates embody such Covered Product), (b)
original equipment manufacturer customers, value added resellers, systems integrators and other
third parties that are authorized by NetIQ to lease, resell or redistribute a Covered Product and
require a license under the Assigned Patents, to exercise such rights, and (c) end users and
resellers, to the extent necessary to use or resell (respectively) a Covered Product.
Notwithstanding the foregoing or anything in this Amendment to the contrary, NetIQ may not grant a
sublicense under this Section 4 (other than the right to use a Covered Product as an end user or in
accordance with Section 4.2(a) above) to, and the rights granted to NetIQ under this Section 4 may
not otherwise extend to, any of the third parties listed on Exhibit C (including their successors
or assigns) or any Affiliates of any such entities. As used herein, the term “Affiliate” means any
wholly- or majority-owned subsidiary of such third party, any parent of such third party that
holds a majority of the interest in such third party, and any other wholly- or majority-owned
subsidiary of such parent (in each case, whether such ownership is direct or indirect).

5. Effect of Amendment.

     Except as expressly modified herein, the terms and conditions of the Agreement, including the
provisions of Section 25.6, shall remain in full force and effect. This Amendment, together with
the Agreement and the Exhibits attached thereto, all of which are incorporated by reference as
though fully set forth in this Amendment, constitutes the entire understanding and agreement
between the parties hereto and supersedes any and all prior or contemporaneous representations,
understandings and agreements between Ixia and NetIQ with respect to the subject matter hereof, all
of which are merged herein. This Amendment shall not be modified, amended or in any way altered
except by an instrument in writing signed by an officer of NetIQ and an officer of Ixia.

6. Counterparts.

     This Amendment may be executed in counterparts, each of which shall be deemed an original and
all of which together shall constitute one and the same instrument.
