                              REGISTRATION RIGHTS

         SECTION 2.01. Shelf Registration. (a) Not later than the later of (i)

market transactions or privately negotiated purchases.

          (b) Parent agrees to use reasonable efforts to have the Shelf
Registration declared effective promptly and to maintain the effectiveness of
the Shelf Registration for one year.

         (c) If at any time, as a result of the existence of nonpublic material
information or for other legitimate reasons Parent determines, after
consultation with its counsel, that the sale of Registrable Securities pursuant
to the Shelf Registration would be prejudicial to Parent, Parent may send to
the Holders and to its transfer agent a notice (a "Blackout Notice") suspending
for up to 45 days the filing of the Shelf Registration or the sale of
Registrable Securities pursuant to the Shelf Registration Statement; provided
that Parent may send such Blackout Notice at any time between the third month
of any fiscal quarter and the announcement of earnings but, at any other time
with any rolling twelve (12) month period, it shall not send more than two (2)
other Blackout Notices.

         (d) Each Holder agrees, in the event of an underwritten offering for
Parent (whether for the account of Parent or otherwise) not to offer, sell,
contract to sell or otherwise dispose of any Registrable Securities, or any
securities convertible into or exchangeable or exercisable for such securities,
including any sale pursuant to Rule 144 under the 1933 Act (except as part of
such underwritten offering), during the 14 days prior to, and during the 30-day
period (or such lesser period as the lead or managing underwriters may require)

retained by Parent

                                       3

<PAGE>

in connection with such registration. The Selling Holders shall pay (x) any
fees, discounts or commissions attributable to the sale of Registrable
Securities, (y) fees and expenses of counsel for the Selling Holders, if any,
and (z) any out-of-pocket expenses of the Selling Holders.

                                   ARTICLE 3
                        INDEMNIFICATION AND CONTRIBUTION

         SECTION 3.01. Indemnification by Parent. Parent agrees to indemnify
and hold harmless each Selling Holder and its Affiliates and their respective
officers, directors, partners, stockholders, members, employees, from and
against any and all losses, claims, damages, liabilities, costs and expenses
(including reasonable attorneys' fees) caused by, arising out of, resulting
from or related to any untrue statement or alleged untrue statement of a
material fact contained in any registration statement or prospectus relating to
the Registrable Securities (as amended or supplemented if Parent shall have
furnished any amendments or supplements thereto) or any preliminary prospectus,
or caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages, liabilities, costs
and expenses are caused by or contained in or based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in such
registration statement, prospectus or preliminary prospectus in reliance upon
and in conformity with any information furnished in writing to Parent by or on
behalf of such Selling Holder expressly for use therein or by the Selling
Holder's failure to deliver a copy of the registration statement or prospectus
or any amendments or supplements thereto after Parent has furnished the Selling
Holders with copies of the same.

         SECTION 3.02. Indemnification by the Selling Holders . Each Selling
Holder agrees to indemnify and hold harmless Parent, its officers and
directors, the Accredited Stockholders, the Key Employee Stockholders, and each
Person, if any, which controls Parent within the meaning of either Section 15
of the 1933 Act or Section 20 of the 1934 Act to the same extent as the
foregoing indemnity from Parent to each Selling Holder, but only with reference
to information furnished in writing by or on behalf of such Selling Holder
expressly for use in any registration statement or prospectus relating to the
Registrable Securities, or any amendment or supplement thereto, or any
preliminary prospectus.

         SECTION 3.03.  Conduct of Indemnification Proceedings.  In case any
proceeding (including any governmental investigation) shall be instituted
involving any Person in respect of which indemnity may be sought pursuant to

                                       4

<PAGE>

Section 3.01 or Section 3.02, such Person (the "Indemnified Party") shall
promptly notify the Person against whom such indemnity may be sought (the
"Indemnifying Party") in writing and the Indemnifying Party, upon the request
of the Indemnified Party, shall retain counsel reasonably satisfactory to such
Indemnified Party to represent such Indemnified Party and any others the
Indemnifying Party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party unless (i) the Indemnifying Party and the Indemnified
Party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the Indemnified Party and the Indemnifying Party and, in the written
opinion of counsel for the Indemnified Party, representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the Indemnifying Party shall not,
in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the fees and expenses of more than one separate
firm of attorneys (in addition to any local counsel) at any time for all such
Indemnified Parties, and that all such fees and expenses shall be reimbursed as
they are incurred. In the case of any such separate firm for the Indemnified
Parties, such firm shall be designated in writing by the Indemnified Parties
and be reasonably satisfactory to the Indemnifying Party. The Indemnifying
Party shall not be liable for any settlement of any proceeding effected without
its written consent, but if settled with such consent, or if there be a final
judgment for the plaintiff, the Indemnifying Party shall indemnify and hold
harmless such Indemnified Parties from and against any loss or liability (to
the extent stated above) by reason of such settlement or judgment.

         SECTION 3.04. Contribution. If an indemnification provided for in this
Article 3 is held by a court of competent jurisdiction to be unavailable to an
Indemnified Party in respect of any loss, claim, damage or liability, then the
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall to
the fullest extent permitted by law contribute to the amount paid or payable by
such Indemnified Party as a result of such loss, claim, damage or liability in
such proportion as is appropriate to reflect the relative fault of such
Indemnifying Party in connection with the statements or omissions that resulted
in such loss, claim, damage or liability, as well as any other relevant
equitable considerations. The relative fault of the Indemnifying Party and the
Indemnified Party, as well as any other parties, shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by each such party

                                       5

<PAGE>

and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

         Parent and each Selling Holder agrees that it would not be just and
equitable if contribution pursuant to this Section were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an Indemnified Party as a result of
the losses, claims, damages or liabilities referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such
Indemnified Party in connection with investigating or defending any such action
or claim. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the 1933 Act) shall be entitled to contribution from any
Person who was not guilty of such fraudulent misrepresentation.

                                   ARTICLE 4
                                 MISCELLANEOUS

         SECTION 4.01.  Notices.  All notices, requests and other communications
to any party hereunder shall be in writing (including facsimile transmission)

not to have been received until the next succeeding business day in the place

         SECTION 4.02. Rule 144. Parent covenants that it will file any reports
required to be filed by it under the 1933 Act and the 1934 Act and that it will
take such further action as the Holders may reasonably request to the extent
required from time to time to enable the Holders to sell Registrable Securities
without registration under the 1933 Act within the limitation of the exemptions
provided by Rule 144 under the 1933 Act, as such Rule may be amended from time
to time, or any similar rule or regulation hereafter adopted by the Commission.

         SECTION 4.03. Termination. The registration rights granted under this
Agreement will terminate with respect to any Holder on the later of the first
anniversary of the effectiveness of the Shelf Registration or when all
Registrable Securities held by such Holder can be sold under Rule 144 during
any 3 month period.

         SECTION 4.04. Successors and Assigns. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, provided that no party may assign, delegate
or otherwise transfer any rights or obligations under this Agreement, other
than by Parent to NetIQ Corporation, without the consent of each other party
hereto.

enforce any provision of, or based on any matter arising out of or in

state court, and each of the parties hereby consents to the jurisdiction of
such courts (and of the appropriate appellate courts therefrom) in any such
suit, action or proceeding and irrevocably waives, to the fullest extent
permitted by law, any objection that it may now or hereafter have to the laying
of the venue of any such suit, action or proceeding in any such court or that
any such suit, action or proceeding brought in any such court has been brought
in an inconvenient forum. Process in any such suit, action or proceeding may be

                       FORM OF RESTRICTED STOCK AGREEMENT

         THIS AGREEMENT is made between _______________________ (the "Key
Employee") and Mission Critical Software, Inc. (the "Parent") as of March 10,
2000.

                                    RECITALS

         WHEREAS, Parent and Ganymede Software, Inc. (the "Company") have
entered into an Agreement and Plan of Merger (the "Merger Agreement") dated
March 10, 2000 which provides for the merger of a wholly-owned subsidiary of
Parent with and into Ganymede (the "Merger") ;

         WHEREAS, the Key Employee and Parent have entered into a Stock
Purchase Agreement (the "Stock Purchase Agreement") dated March 10, 2000 which
provides for the sale of all shares of capital stock of the Company held by Key
Employee to the Parent in consideration of certain shares of the Parent.

         WHEREAS, it is contemplated under the Stock Purchase Agreement that
Parent and Key Employee will deposit or cause to be deposited into escrow at
the closing thereof (the "Closing") certificates representing seventy-five
percent (75%) of the shares of Parent Stock (as defined in the Stock Purchase
Agreement), issued in the name of Key Employee pursuant to the Stock Purchase
Agreement (the "Restricted Shares") and to be held and disbursed by the Escrow
Agent in accordance with Section 2 of this Agreement; and

         WHEREAS, it is a condition to the closing of the Merger that Key
Employee will enter into this Agreement with Parent

         NOW, THEREFORE, intending to be legally bound, the parties hereto
agree as follows:

         SECTION 1.  Repurchase Option.

          (a) Subject to the provisions of Section 1(b) of this Agreement, for
so long as Key Employee continues to serve in the employ of Parent, its
subsidiaries and successors in interest, Key Employee shall receive one-third
of such Key Employee's Restricted Shares on each of the first, second and third
anniversaries of the Effective Time, as that term is defined in the Merger
Agreement pursuant to the procedures set forth in Section 2 of this Agreement.

<PAGE>

           (b) If Key Employee shall cease to be an employee of Parent, its
subsidiaries or successors in interest for any reason other than the death or
Disability (as defined in the employment agreement entered into by Parent and
such Key Employee dated as of the date hereof), termination by the Parent
without Cause (as defined herein), or resignation by Key Employee for Good
Reason (as defined herein), Parent shall have the right to purchase from Key
Employee, or Key Employee's personal representative, as the case may be, that
portion of the Restricted Shares which has not vested as of the date of such
termination (the "Unvested Shares") at a price per share equal to the quotient
of (i) $.01 and (ii) the Exchange Ratio, as that term is defined in the Merger
Agreement (the "Repurchase Option"); provided, however, that in the event Key
Employee is terminated by the Parent without Cause, for death or Disability, or
if Key Employee resigns for Good Reason, the Repurchase Option shall terminate,
and all Restricted Shares be disbursed pursuant to Section 2(d) of this
agreement.

         For purposes of this Agreement, the term "Cause" shall be defined as:

                  (i) the willful and continued failure of Key Employee to
                  substantially perform the duties required of him under the
                  employment agreement entered into by Parent and Key Employee
                  dated as of the date hereof in a manner satisfactory to the
                  Board of Directors of Parent (the "Board") or willful refusal
                  to implement decisions of the Board made in good faith; in
                  each case, which is materially injurious, monetarily or
                  otherwise, to Parent, its affiliates, the Company or to the
                  portion of Parent's, its affiliates' or the Company's
                  business operations over which Key Employee exercises
                  substantial responsibility;

                  (ii) the willful engaging by Key Employee in misconduct which
                  is materially injurious, monetarily or otherwise, to Parent,
                  its affiliates, the Company or to the portion of the
                  Parent's, its affiliates' or the Company's business
                  operations over which Key Employee exercises substantial
                  responsibility;

                  (iii) any dishonesty by Key Employee in his dealings with
                  Parent which is materially injurious, monetarily or
                  otherwise, to Parent, its affiliates, the Company or to the
                  portion of Parent's, its affiliates' or the Company's
                  business operations over which Key Employee exercises
                  substantial responsibility or the commission of fraud by Key
                  Employee;

                  (iv) the indictment of Key Employee for any felony (other
                  than an arrestable traffic offense) or other crime involving
                  dishonesty or

                                       2

<PAGE>

                  the conviction (or plea of guilty or nolo contendere) of Key
                  Employee of any felony (other than an arrestable traffic
                  offense) or other crime involving dishonesty; or

                  (v) any violation of any covenant or restriction contained in
                  Section 11 of the employment agreement entered into by Parent
                  and Key Employee dated as of the date hereof or any violation
                  which is materially injurious, monetarily or otherwise, to
                  Parent, its affiliates, the Company or to the portion of
                  Parent's, its affiliates' or the Company's business
                  operations over which Key Employee exercises substantial
                  responsibility of any covenant or restriction contained in
                  Section 12 of the employment agreement entered into by Parent
                  and Key Employee dated as of the date hereof.

         provided, however, that, for purposes of this Agreement, Parent shall
not be able to terminate the employment of Key Employee for Cause except in
accordance with the following procedures. A majority of the Board must first
give Key Employee a written notice (the "Notice of Deficiency"). The Notice of
Deficiency shall specify the deficiencies in Key Employee's performance of his
duties. Key Employee shall have a period of thirty (30) days, commencing on
receipt of the Notice of Deficiency, in which to cure the deficiencies (if such
deficiencies are curable) contained in the Notice of Deficiency. If Key
Employee does not cure the deficiencies to the reasonable satisfaction of a
majority of the Board, within such thirty (30) day period, the Board or Parent
shall have the right to immediately terminate Key Employee's employment for
Cause. Nothing herein shall limit the right of Key Employee or Key Employee's
beneficiaries to contest the validity or correctness of any of the Board's
determinations referenced above; provided that any and all contests, disputes
or disagreements shall be resolved through an arbitration proceeding performed
in accordance with the then-current Employment Arbitration Rules of Judicial
Arbitration & Mediation Services, Inc. The provisions relating to this Notice
of Deficiency may be invoked by the Board any number of times and cure of
deficiencies contained in any Notice of Deficiency shall not be construed as a
waiver of this subsection nor prevent the Board from issuing any subsequent
Notices of Deficiency. For all purposes of this Agreement, termination for
Cause shall also be deemed to have occurred upon Key Employee's resignation if,
because of existing facts and circumstances, a subsequent termination by the
Board or Parent for Cause could reasonably have been foreseen. For all purposes
of this Agreement, no act, or failure to act, on Key Employee's part shall be
considered "willful" unless done, or omitted to be done, by him not in good

(50) mile radius of the Raleigh, Durham, Chapel Hill, North Carolina
metropolitan area, without the consent of Key Employee.

          (c) Parent may exercise its Repurchase Option by delivering
personally or by registered mail, to Key Employee (or his transferee or legal
representative, as the case may be), within ninety (90) days of the
termination, a notice in writing indicating Parent's intention to exercise the
Repurchase Option and setting forth a date for closing not later than thirty
(30) days from the mailing of such notice. The closing shall take place at
Parent's office. At the closing, the holder of the certificates for the
Unvested Shares being transferred shall deliver the stock certificate or
certificates evidencing the Unvested Shares, and Parent shall deliver the
purchase price therefor.

          (d) At its option, Parent may elect to make payment for the Unvested
Shares to a bank selected by Parent. Parent shall avail itself of this option
by a notice in writing to Key Employee stating the name and address of the
bank, date of closing, and waiving the closing at Parent's office.

          (e) If Parent does not elect to exercise the Repurchase Option
conferred above by giving the requisite notice within ninety (90) days

to Parent.

          (b) To ensure the availability for delivery of Key Employee's
Unvested Shares upon repurchase by Parent pursuant to the Repurchase Option
under Section 1, Key Employee hereby appoints the corporate secretary of

attorney-in-fact to sell, assign and transfer unto Parent, such Unvested
Shares, if any, repurchased by Parent pursuant to the Repurchase Option and

Key Employee attached as Exhibit B hereto, until Parent exercises its purchase
right as provided in Section 1, until such Unvested Shares are vested, or until
such time as this Agreement no longer is in effect. As a further condition to
Parent's obligations under this Agreement, the spouse of the Key Employee, if
any, shall execute and deliver to Parent the Consent of Spouse attached hereto
as Exhibit B.

         (c) Upon vesting of the Unvested Shares, the escrow agent shall
promptly deliver to the Key Employee the certificate or certificates
representing such Shares in the escrow agent's possession belonging to the Key
Employee, and the escrow agent shall be discharged of all further obligations
hereunder; provided, however, that the escrow agent shall nevertheless retain
such certificate or certificates as escrow agent if so required pursuant to
other restrictions imposed pursuant to this Agreement.

         (d) In the event Key Employee's employment is terminated by Parent
without Cause or upon his death or Disability, or if Key Employee resigns for
Good Reason, the Repurchase Option shall terminate, and all Restricted Shares
shall be released by the escrow agent to such terminated Key Employee within
fifteen (15) business days following such termination.

          (e) Parent, or its designee, shall not be liable for any act it may
do or omit to do with respect to holding the Shares in escrow and while acting
in good faith and in the exercise of its judgment.

          (f) Transfer or sale of the Shares is subject to restrictions on
transfer imposed by any applicable state and federal securities laws. Any
transferee shall hold such Shares subject to all the provisions hereof and the
Exercise Notice executed by the Key Employee with respect to any Unvested
Shares purchased by Key Employee and shall acknowledge the same by signing a
copy of this Agreement.

         SECTION 3. Ownership, Voting Rights, Duties. This Agreement shall not
