                              EMPLOYMENT AGREEMENT

        THIS AGREEMENT is entered into as of January 1, 2002, by and between
Jeffrey R. Rodek (the "Employee"), an individual residing at the address set
forth on the signature page hereof, and HYPERION SOLUTIONS CORPORATION, a
Delaware corporation (the "Company"). This agreement replaces the Employment
Agreement dated as of October 11, 1999, provided that, except to the extend
specifically covered herein, nothing in this agreement is intended to affect the
terms of Restricted Stock, Stock Options or the loan granted under the terms of
the October 11, 1999 agreement.

        1. DUTIES AND SCOPE OF EMPLOYMENT.

           (a) POSITION. For the term of his employment under this Agreement
("Employment"), the Company agrees to employ the Employee in the position of
Chief Executive Officer. The Employee shall report to the Company's Board of
Directors.

           (b) OBLIGATIONS TO THE COMPANY. During the term of his Employment,
the Employee shall devote his full business efforts and time to the Company.
During the term of his Employment, without the prior written approval of the
Company (which shall not be unreasonably withheld), the Employee shall not
render services in any capacity to any other person or entity and shall not act
as a sole proprietor, partner or managing member of any other person or entity
or as a shareholder owning more than one percent of the stock of any other
corporation, provided however that Employee may own up to two percent of the
stock of New Roads Inc. The foregoing, however, shall not preclude the Employee
from engaging in reasonable community, school or charitable activities. The
Employee shall comply with the Company's policies and rules, as they may be in
effect from time to time during the term of his Employment.

           (c) NO CONFLICTING OBLIGATIONS. The Employee represents and warrants
to the Company that he is under no obligations or commitments, whether
contractual or otherwise, that are inconsistent with his obligations under this
Agreement. The Employee represents and warrants that he will not use or
disclose, in connection with his employment by the Company, any trade secrets or
other proprietary information or intellectual property in which he or any other
person has any right, title or interest and that his employment by the Company
as contemplated by this Agreement will not infringe or violate the rights of any
other person. The Employee represents and warrants to the Company that he has
returned all property and confidential information belonging to any prior
employer.

        2. CASH AND INCENTIVE COMPENSATION.

           (a) SALARY. The Company shall pay the Employee as compensation for
his services a base salary at a gross annual rate of not less than $400,000.
Such salary shall

<PAGE>

be payable in accordance with the Company's standard payroll procedures. (The
annual compensation specified in this Subsection (a), together with any
increases in such compensation that the Company may grant from time to time, is
referred to in this Agreement as "Base Compensation.").

           (b) INCENTIVE BONUSES. The Employee shall be eligible to be
considered for an annual incentive bonus with a target amount equal to 50% of
his Base Compensation. Such bonus (if any) shall be awarded based on objective
or subjective criteria established in advance by the Company's Board of
Directors (the "Board") or its Compensation Committee. Bonus will be payable on
a pro rated basis starting at achievement of a minimum of 80% targeted goal.
Achievement above targeted goal will increase percent of Base Compensation
payable as a bonus up to a maximum of 75% of Base Compensation The
determinations of the Board or such Committee with respect to such bonus shall
be final and binding.

        3. LOAN FORGIVENESS. The Company has loaned Employee one million dollars
($1,000,000). This note bears interest and is due in full on October 11, 2005
(or earlier in certain events.) The Company will forgive 25% of the principle,
or two hundred fifty thousand dollars ($250,000), and the interest accrued with
respect to such 25%, for any year, commencing with the year ending June, 2002,
in which the earnings per share of the Company equal or exceed targets set by
the Compensation Committee of the Board of Directors. In the event that the
Company's earnings per share are under or over such earnings per share target,
then the Company will consider forgiving less or more, respectively, of the 25%
amount, provided that the Company is only obligated to forgive 25%, and then
only in the event the earnings per share target is met. Employee will be
responsible for paying all personal income tax due on account of any such
forgiveness.

        4. EMPLOYEE BENEFITS. During the term of his Employment, the Employee
shall be eligible to participate in any employee benefit plans maintained by the
Company for similarly situated employees, subject in each case to the generally
applicable terms and conditions of the plan in question and to the
determinations of any person or committee administering such plan.

        In addition to providing the foregoing benefits to Employee, the Company
shall:

           (i) reimburse the Employee for the reasonable and customary cost of
        an annual physical examination.

           (ii) provide to the Employee certain income tax services.
        PricewaterhouseCoopers will prepare and sign the Employee's individual
        income tax returns and provide the Employee with estimated tax
        calculations. In addition, the tax professionals at
        PricewaterhouseCoopers will provide the Employee with income tax
        projections to help Employee develop his or her personal financial goals
        and strategies, including planning for the exercise and/or sale of
        option stock.

        5. BUSINESS EXPENSES. During the term of his Employment, the Employee
shall be authorized to incur necessary and reasonable travel, entertainment and
other business expenses in connection with his duties hereunder, including one
hundred percent of all cell phone charges, reasonable costs of travel to and
from employee's home to the Company offices, and the cost of an apartment for

shall reimburse the Employee for such expenses upon presentation of an itemized
account and appropriate supporting documentation, all in accordance with the
Company's generally applicable policies. Any single expenditure in excess of
$10,000 shall require the prior approval of the Company's Chief Financial

        6. TERM OF EMPLOYMENT.

           (a) BASIC RULE. The Company agrees to continue the Employee's
Employment, and the Employee agrees to remain in Employment with the Company,
from the Effective Time until the earlier of:

               (i) The close of the applicable Initial Term or Renewal Period,
        as determined under Subsection (b) below; or

               (ii) The date when the Employee's Employment terminates pursuant
        to Subsection (c) below.

           (b) INITIAL TERM AND RENEWAL PERIODS. The initial term of this
Agreement shall end on January 31, 2003 (the "Initial Term"). Thereafter this
Agreement shall automatically be renewed for successive 12-month periods (the
"Renewal Periods"), unless either party has given the other party written notice
of non-renewal not less than 90 days prior to the close of the Initial Term or
Renewal Period then in effect.

           (c) EARLY TERMINATION. The Employee may terminate his Employment at
any time and for any reason (or no reason) by giving the Company 30 days'
advance notice in writing. The Company may terminate the Employee's Employment
at any time and for any reason (or no reason), and with or without Cause, by
giving the Employee 30 days' advance notice in writing. The Company may also
terminate the Employee's active Employment due to Permanent Disability by giving
the Employee notice in writing. For all purposes under this Agreement,
"Permanent Disability" shall mean that the Employee, at the time notice is
given, has failed to perform his duties under this Agreement for 60 or more
consecutive days or for 90 or more days during any 12-month period as the result
of his incapacity due to physical or mental injury, disability or illness and
which the Company is unable to accommodate reasonably without undue hardship.
The Employee's Employment shall terminate automatically in the event of his
death.

           (d) RIGHTS AND OBLIGATIONS UPON TERMINATION. Except as expressly
provided in Section 7, upon the termination of the Employee's Employment
pursuant to this Section 6, the Employee shall only be entitled to the
compensation, benefits and reimbursements described in Sections 2, 3 and 4 and 5
for the period preceding the effective date of the termination. No incentive
bonus under Section 2(b) shall be payable for the year in which the

<PAGE>

Employee's Employment terminates, unless the applicable bonus program expressly
provides for the payment of a prorated bonus for such year. The payments under
this Agreement shall fully discharge all responsibilities of the Company to the
Employee. The termination of this Agreement shall not limit or otherwise affect
the Employee's obligations under Section 7.

        7. TERMINATION BENEFITS.

           (a) GENERAL RELEASE. Any other provision of this Agreement
notwithstanding, Subsections (b) and (c) below shall not apply unless the
Employee has executed a general release (in a form prescribed by the Company) of
all known and unknown claims that he may then have against the Company or
persons affiliated with the Company. Such release shall include, among other
things, an agreement not to prosecute any legal action or other proceeding based
upon any of such claims. The Employee acknowledges that such release may provide
that in the event of a breach by the Employee of the terms of the release or of
Employee's obligations under Section 7 hereof, the Company shall be entitled to
recover from the Employee all amounts paid under subsections (b) and (c) of this
Section 6, as well as all litigation costs (including attorneys' fees and
expenses) incurred by the Company in connection with such breach.

           (b) SEVERANCE PAY. The Company shall pay the Employee his Base
Compensation for a 12-month period following the effective date of the
termination of his Employment (the "Continuation Period") if:

               (i) The Company terminates the Employee's Employment under
        Section 6(c), or the Employee's employment terminates due to the
        expiration of the term of this agreement without renewal under 6(b);
        except, in each case, for terminations for Cause or Permanent
        Disability; or

               (ii) The Company was subject to a Corporate Transaction/Change in
        Control during the term of this Agreement and, within 12 months
        thereafter, the Employee resigns for Good Reason.

               (iii) During the term of this Agreement, the current Chief
        Executive Officer ("CEO") ceases to serve as the senior executive
        officer of the Company, the Company's Board of Directors appoints a new
        CEO and within six months of the first day of such new CEO's employment
        with the Company, the Employee resigns because the Company has
        significantly diminished the nature or scope of the Employee's
        authority, duties or responsibilities in effect immediately prior to the
        appointment of the new CEO.

Base Compensation under this Subsection (b) shall be paid at the rate in effect
at the time of the termination of Employment and in accordance with the
Company's standard payroll procedures.

           (c) EMPLOYEE BENEFITS. If Subsection (b) above applies, the Company
shall continue the coverage of the Employee and his dependents (if applicable)
under the employee benefit plans described in Section 3 during the Continuation
Period. To the extent that

<PAGE>

such plans or the insurance contracts or provider agreements associated with
such plans do not permit the extension of the Employee's coverage following the
termination of his active employment, the Company shall pay the Employee cash in
an amount equal to the cost to the Company of the coverage that cannot be
provided. The cash payments shall be made in accordance with Subsection (b)
above.

           (d) COBRA. If Subsection (b) above applies, and if the Employee
elects to continue his health insurance coverage under the Consolidated Omnibus
Budget Reconciliation Act ("COBRA") following the termination of his Employment,
then the date of the "qualifying event" for purposes of COBRA shall be the
Employee's last day of active employment.

           (e) DEFINITION OF "CAUSE." For all purposes under this Agreement,
"Cause" shall mean:

               (i) The Employee's misconduct relating to the Company's affairs,
        if such misconduct continues for seven days or more after the Company
        has given the Employee written notice describing such misconduct and
        advising him of the consequences of such misconduct under this
        Agreement; provided that such notice shall be required only with respect
        to the first occurrence of such misconduct; provided further there shall
        be no requirement that the misconduct continue for seven days or more
        with respect to acts for which an employee's employment is specifically
        terminable under the Company's policies and procedures applicable to all
        employees;

               (ii) The Employee's conviction of, or a plea of "guilty" or "no
        contest" to, a felony, or a misdemeanor which calls into question the
        Employee's honesty, under the laws of the United States or any state
        thereof;

               (iii) Any breach of this Agreement, the Employee Proprietary
        Information Agreement between the Employee and the Company, or any other
        agreement between the Employee and the Company;

               (iv) Threats or acts of violence or harassment directed at any

               (v) Fraud or embezzlement involving the assets of the Company or
        its affiliates, customers or suppliers.

The foregoing shall not be deemed an exclusive list of all acts or omissions
that the Company may consider as grounds for the termination of the Employee's
Employment with Cause. Termination for Cause hereunder shall be deemed to be
termination for "Misconduct" under the Company's stock option plans and related
agreements.

Employee's own behalf or on behalf of any other person or entity) the employment
of any employee of the Company or any of the Company's affiliates. During such

the effect of encouraging or inducing, any employee of the Company or any of the

           (c) NON-SOLICITATION OF CUSTOMERS. The parties agree that information
relating to the identities, key contact personnel, preferences, needs and

Company that are, and necessarily will be, used by the Employee in the
solicitation of business from the Company's customers. As a result, during the
period commencing on the date of this Agreement and continuing until the second
anniversary of the date when the Employee's Employment terminated for any
reason, the Employee shall not, directly or indirectly, personally or through
others, solicit or attempt to solicit (on the Employee's own behalf or on behalf

future board of directors or senior management or any of their products or
services.

           (e) INJUNCTIVE RELIEF. The Employee acknowledges and agrees that his
failure to perform any of his covenants in this Section 7 would cause
irreparable injury to the

<PAGE>

Company and cause damages to the Company that would be difficult or impossible
to ascertain or quantify. Accordingly, without limiting any other remedies that
may be available with respect to any breach of this Agreement, the Employee
consents to the entry of an injunction to restrain any breach of this Section 7.

           (f) SURVIVAL. The covenants in this Section 7 shall survive any

is agreed to in writing and signed by the Employee and by an authorized officer
of the Company (other than the Employee). No waiver by either party of any

by the other party shall be considered a waiver of any other condition or
