1.   Purpose.

     (a) The purpose of the Employee Stock Purchase Plan (the "Plan") is to
provide a means by which employees of Rogue Wave Software, Inc., a Delaware
corporation (the "Company"), and its Affiliates, as defined in subparagraph
1(b), which are designated as provided in subparagraph 2(b), may be given an
opportunity to purchase stock of the Company.

     (b) The word "Affiliate" as used in the Plan means any parent corporation
or subsidiary corporation of the Company, as those terms are defined in Sections
424(e) and (f), respectively, of the Internal Revenue Code of 1986, as amended
(the "Code").

     (c) The Company, by means of the Plan, seeks to retain the services of its
employees, to secure and retain the services of new employees, and to provide
incentives for such persons to exert maximum efforts for the success of the
Company.

     (d) The Company intends that the rights to purchase stock of the Company
granted under the Plan be considered options issued under an "employee stock
purchase plan" as that term is defined in Section 423(b) of the Code.

2.   Administration.

     (a) The Plan shall be administered by the Board of Directors (the "Board")
of the Company unless and until the Board delegates administration to a
Committee, as provided in subparagraph 2(c).  Whether or not the Board has
delegated administration, the Board shall have the final power to determine all
questions of policy and expediency that may arise in the administration of the
Plan.

     (b) The Board shall have the power, subject to, and within the limitations
of, the express provisions of the Plan:

         (i)   To determine when and how rights to purchase stock of the Company
shall be granted and the provisions of each offering of such rights (which need
not be identical).

         (ii)  To designate from time to time which Affiliates of the Company
shall be eligible to participate in the Plan.
<PAGE>

         (iii) To construe and interpret the Plan and rights granted under it,
and to establish, amend and revoke rules and regulations for its administration.
The Board, in the exercise of this power, may correct any defect, omission or
inconsistency in the Plan, in a manner and to the extent it shall deem necessary
or expedient to make the Plan fully effective.

         (iv)  To amend the Plan as provided in paragraph 13.

         (v)   Generally, to exercise such powers and to perform such acts as
the Board deems necessary or expedient to promote the best interests of the
Company and its Affiliates and to carry out the intent that the Plan be treated
as an "employee stock purchase plan" within the meaning of Section 423 of the
Code.

     (c) The Board may delegate administration of the Plan to a Committee
composed of not fewer than two (2) members of the Board (the "Committee")
constituted in accordance with the requirements of Rule 16b-3 under the
Securities Exchange Act of 1934 (the "Exchange Act" and "Rule 16b-3"); provided
that the Committee shall be required to satisfy the foregoing requirements only
to the extent required to exempt transactions under the Plan pursuant to Rule
16b-3.  If administration is delegated to a Committee, the Committee shall have,
in connection with the administration of the Plan, the powers theretofore
possessed by the Board, subject, however, to such resolutions, not inconsistent
with the provisions of the Plan, as may be adopted from time to time by the
Board.  The Board may abolish the Committee at any time and revest in the Board
the administration of the Plan.

3.   Shares Subject to the Plan.

     (a) Subject to the provisions of paragraph 12 relating to adjustments upon
changes in stock and subject to the increase in the number of reserved shares
described below, the stock that may be sold pursuant to rights granted under the
Plan shall not exceed in the aggregate six hundred fifty thousand (650,000)
shares of Common Stock (the "Reserved Shares").  As of each January 1, beginning
with January 1, 2001, and continuing through and including January 1, 2009, the
number of Reserved Shares will be increased automatically by the lesser of (i)
three percent (3%) of the total number of shares of Common Stock outstanding on
such January 1, or (ii) three hundred thousand (300,000) shares.  If any right
granted under the Plan shall for any reason terminate without having been
exercised, the Common Stock not purchased under such right shall again become
available for the Plan.

     (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

4.   Grant of Rights; Offering.

     The Board or the Committee may from time to time grant or provide for the
grant of rights to purchase Common Stock of the Company under the Plan to
eligible employees (an "Offering") on a date or dates (the "Offering Date(s)")
selected by the Board or the Committee.  Each Offering shall be in such form and
shall contain such terms and conditions as the Board or the Committee shall deem
appropriate, which shall comply with the requirements of Section 423(b)(5) of
the Code that all employees granted rights to purchase stock under the Plan
shall have the same rights and privileges.  The terms and conditions of an
Offering shall be

                                       2
<PAGE>

incorporated by reference into the Plan and treated as part of the Plan. The
provisions of separate Offerings need not be identical, but each Offering shall
include (through incorporation of the provisions of this Plan by reference in
the document comprising the Offering or otherwise) the period during which the
Offering shall be effective, which period shall not exceed twenty-seven (27)
months beginning with the Offering Date, and the substance of the provisions
contained in paragraphs 5 through 8, inclusive.

5.   Eligibility.

     (a) Rights may be granted only to employees of the Company or, as the Board
or the Committee may designate as provided in subparagraph 2(b), to employees of
any Affiliate of the Company.  Except as provided in subparagraph 5(b), an
employee of the Company or any Affiliate shall not be eligible to be granted
rights under the Plan, unless, on the Offering Date, such employee has been in
the employ of the Company or any Affiliate for such continuous period preceding
such grant as the Board or the Committee may require, but in no event shall the
required period of continuous employment be equal to or greater than two (2)
years.  In addition, unless otherwise determined by the Board or the Committee
and set forth in the terms of the applicable Offering, no employee of the
Company or any Affiliate shall be eligible to be granted rights under the Plan,
unless, on the Offering Date, such employee's customary employment with the
Company or such Affiliate is for at least twenty (20) hours per week and at
least five (5) months per calendar year.

     (b) The Board or the Committee may provide that, each person who, during
the course of an Offering, first becomes an eligible employee of the Company or
designated Affiliate will, on a date or dates specified in the Offering which
coincides with the day on which such person becomes an eligible employee or
occurs thereafter, receive a right under that Offering, which right shall
thereafter be deemed to be a part of that Offering.  Such right shall have the
same characteristics as any rights originally granted under that Offering, as
described herein, except that:

         (i)    the date on which such right is granted shall be the "Offering
Date" of such right for all purposes, including determination of the exercise
price of such right;

         (ii)   the period of the Offering with respect to such right shall
begin on its Offering Date and end coincident with the end of such Offering; and

         (iii)  the Board or the Committee may provide that if such person first
becomes an eligible employee within a specified period of time before the end of
the Offering, he or she will not receive any right under that Offering.

     (c) No employee shall be eligible for the grant of any rights under the
Plan if, immediately after any such rights are granted, such employee owns stock
possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of the Company or of any Affiliate.  For purposes of
this subparagraph 5(c), the rules of Section 424(d) of the Code shall apply in
determining the stock ownership of any employee, and stock which such employee
may purchase under all outstanding rights and options shall be treated as stock
owned by such employee.

                                       3
<PAGE>

     (d) An eligible employee may be granted rights under the Plan only if such
rights, together with any other rights granted under "employee stock purchase
plans" of the Company and any Affiliates, as specified by Section 423(b)(8) of
the Code, do not permit such employee's rights to purchase stock of the Company
or any Affiliate to accrue at a rate which exceeds twenty-five thousand dollars
($25,000) of fair market value of such stock (determined at the time such rights
are granted) for each calendar year in which such rights are outstanding at any
time.

     (e) Officers of the Company and any designated Affiliate shall be eligible
to participate in Offerings under the Plan, provided, however, that the Board
may provide in an Offering that certain employees who are highly compensated
employees within the meaning of Section 423(b)(4)(D) of the Code shall not be
eligible to participate.

6.   Rights; Purchase Price.

     (a) On each Offering Date, each eligible employee, pursuant to an Offering
made under the Plan, shall be granted the right to purchase up to the number of
shares of Common Stock of the Company purchasable with a percentage designated
by the Board or the Committee not exceeding fifteen percent (15%) of such
employee's Earnings (as defined by the Board or the Committee in each Offering)
during the period which begins on the Offering Date (or such later date as the
Board or the Committee determines for a particular Offering) and ends on the
date stated in the Offering, which date shall be no later than the end of the
Offering.  The Board or the Committee shall establish one or more dates during
an Offering (the "Purchase Date(s)") on which rights granted under the Plan
shall be exercised and purchases of Common Stock carried out in accordance with
such Offering.

     (b) In connection with each Offering made under the Plan, the Board or the
Committee may specify a maximum number of shares that may be purchased by any
employee as well as a maximum aggregate number of shares that may be purchased
by all eligible employees pursuant to such Offering.  In addition, in connection
with each Offering that contains more than one Purchase Date, the Board or the
Committee may specify a maximum aggregate number of shares which may be
purchased by all eligible employees on any given Purchase Date under the
Offering.  If the aggregate purchase of shares upon exercise of rights granted
under the Offering would exceed any such maximum aggregate number, the Board or
the Committee shall make a pro rata allocation of the shares available in as
nearly a uniform manner as shall be practicable and as it shall deem to be
equitable.

     (c) The purchase price of stock acquired pursuant to rights granted under
the Plan shall be not less than the lesser of:

         (i)    an amount equal to eighty-five percent (85%) of the fair market
value of the stock on the Offering Date; or

         (ii)   an amount equal to eighty-five percent (85%) of the fair market
value of the stock on the Purchase Date.

7.   Participation; Withdrawal; Termination.

                                       4
<PAGE>

     (a) An eligible employee may become a participant in the Plan pursuant to
an Offering by delivering a participation agreement to the Company within the
time specified in the Offering, in such form as the Company provides.  Each such
agreement shall authorize payroll deductions of up to the maximum percentage
specified by the Board or the Committee of such employee's Earnings during the
Offering (as defined by the Board or Committee in each Offering).  The payroll
deductions made for each participant shall be credited to an account for such
participant under the Plan and shall be deposited with the general funds of the
Company.  A participant may reduce (including to zero) or increase such payroll
deductions, and an eligible employee may begin such payroll deductions, after
the beginning of any Offering only as provided for in the Offering.  A
participant may make additional payments into his or her account only if
specifically provided for in the Offering and only if the participant has not
had the maximum amount withheld during the Offering.

     (b) At any time during an Offering, a participant may terminate his or her
payroll deductions under the Plan and withdraw from the Offering by delivering
to the Company a notice of withdrawal in such form as the Company provides.
Such withdrawal may be elected at any time prior to the end of the Offering
except as provided by the Board or the Committee in the Offering.  Upon such
withdrawal from the Offering by a participant, the Company shall distribute to
such participant all of his or her accumulated payroll deductions (reduced to
the extent, if any, such deductions have been used to acquire stock for the
participant) under the Offering, without interest, and such participant's
interest in that Offering shall be automatically terminated.  A participant's
withdrawal from an Offering will have no effect upon such participant's
eligibility to participate in any other Offerings under the Plan but such
participant will be required to deliver a new participation agreement in order
to participate in subsequent Offerings under the Plan.

     (c) Rights granted pursuant to any Offering under the Plan shall terminate
immediately upon cessation of any participating employee's employment with the
Company and any designated Affiliate, for any reason, and the Company shall
distribute to such terminated employee all of his or her accumulated payroll
deductions (reduced to the extent, if any, such deductions have been used to
acquire stock for the terminated employee) under the Offering, without interest.

     (d) Rights granted under the Plan shall not be transferable by a
participant otherwise than by will or the laws of descent and distribution, or
by a beneficiary designation as provided in paragraph 14 and, otherwise during
his or her lifetime, shall be exercisable only by the person to whom such rights
are granted.

8.   Exercise.

     (a) On each Purchase Date specified therefor in the relevant Offering, each
participant's accumulated payroll deductions and other additional payments
specifically provided for in the Offering (without any increase for interest)
will be applied to the purchase of whole shares of stock of the Company, up to
the maximum number of shares permitted pursuant to the terms of the Plan and the
applicable Offering, at the purchase price specified in the Offering.  No
fractional shares shall be issued upon the exercise of rights granted under the
Plan.  The amount, if any, of accumulated payroll deductions remaining in each
participant's account after the purchase of shares which is less than the amount
required to purchase one share of stock on the

                                       5
<PAGE>

final Purchase Date of an Offering shall be held in each such participant's
account for the purchase of shares under the next Offering under the Plan,
unless such participant withdraws from such next Offering, as provided in
subparagraph 7(b), or is no longer eligible to be granted rights under the Plan,
as provided in paragraph 5, in which case such amount shall be distributed to
the participant after such final Purchase Date, without interest. The amount, if
any, of accumulated payroll deductions remaining in any participant's account
after the purchase of shares which is equal to the amount required to purchase
whole shares of stock on the final Purchase Date of an Offering shall be
distributed in full to the participant after such Purchase Date, without
interest.

     (b) No rights granted under the Plan may be exercised to any extent unless
the shares to be issued upon such exercise under the Plan (including rights
granted thereunder) are covered by an effective registration statement pursuant
to the Securities Act of 1933, as amended (the "Securities Act") and the Plan is
in material compliance with all applicable state, foreign and other securities
and other laws applicable to the Plan.  If on a Purchase Date in any Offering
hereunder the Plan is not so registered or in such compliance, no rights granted
under the Plan or any Offering shall be exercised on such Purchase Date, and the
Purchase Date shall be delayed until the Plan is subject to such an effective
registration statement and such compliance, except that the Purchase Date shall
not be delayed more than twelve (12) months and the Purchase Date shall in no
event be more than twenty-seven (27) months from the Offering Date.  If on the
Purchase Date of any Offering hereunder, as delayed to the maximum extent
permissible, the Plan is not registered and in such compliance, no rights
granted under the Plan or any Offering shall be exercised and all payroll
deductions accumulated during the Offering (reduced to the extent, if any, such
deductions have been used to acquire stock) shall be distributed to the
participants, without interest.

9.   Covenants of the Company.

     (a) During the terms of the rights granted under the Plan, the Company
shall keep available at all times the number of shares of stock required to
satisfy such rights.

     (b) The Company shall seek to obtain from each federal, state, foreign or
other regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to issue and sell shares of stock upon exercise of
the rights granted under the Plan.  If, after reasonable efforts, the Company is
unable to obtain from any such regulatory commission or agency the authority
which counsel for the Company deems necessary for the lawful issuance and sale
of stock under the Plan, the Company shall be relieved from any liability for
failure to issue and sell stock upon exercise of such rights unless and until
such authority is obtained.

10.  Use of Proceeds from Stock.

     Proceeds from the sale of stock pursuant to rights granted under the Plan
shall constitute general funds of the Company.

11.  Rights as a Stockholder.

     A participant shall not be deemed to be the holder of, or to have any of
the rights of a holder with respect to, any shares subject to rights granted
under the Plan unless and until the

                                       6
<PAGE>

participant's shareholdings acquired upon exercise of rights under the Plan are
recorded in the books of the Company.

12.  Adjustments upon Changes in Stock.

     (a) If any change is made in the stock subject to the Plan, or subject to
any rights granted under the Plan (through merger, consolidation,
reorganization, recapitalization, reincorporation, stock dividend, dividend in
property other than cash, stock split, liquidating dividend, combination of
shares, exchange of shares, change in corporate structure or other transaction
not involving the receipt of consideration by the Company), the Plan and
outstanding rights will be appropriately adjusted in the class(es) and maximum
number of shares subject to the Plan and the class(es) and number of shares and
price per share of stock subject to outstanding rights.  Such adjustments shall
be made by the Board or the Committee, the determination of which shall be
final, binding and conclusive.  (The conversion of any convertible securities of
the Company shall not be treated as a "transaction not involving the receipt of
consideration by the Company.")

     (b) In the event of:  (1) a dissolution or liquidation of the Company; (2)
a merger or consolidation in which the Company is not the surviving corporation;
(3) a reverse merger in which the Company is the surviving corporation but the
shares of the Company's Common Stock outstanding immediately preceding the
merger are converted by virtue of the merger into other property, whether in the
form of securities, cash or otherwise; or (4) the acquisition by any person,
entity or group within the meaning of Section 13(d) or 14(d) of the Exchange Act
or any comparable successor provisions (excluding any employee benefit plan, or
related trust, sponsored or maintained by the Company or any Affiliate of the
Company) of the beneficial ownership (within the meaning of Rule 13d-3
promulgated under the Exchange Act, or comparable successor rule) of securities
of the Company representing at least fifty percent (50%) of the combined voting
power entitled to vote in the election of directors, then, as determined by the
Board in its sole discretion (i) any surviving or acquiring corporation may
assume outstanding rights or substitute similar rights for those under the Plan,
(ii) such rights may continue in full force and effect, or (iii) participants'
accumulated payroll deductions may be used to purchase Common Stock immediately
prior to the transaction described above and the participants' rights under the
ongoing Offering terminated.

13.  Amendment of the Plan.

     (a) The Board at any time, and from time to time, may amend the Plan.
However, except as provided in paragraph 12 relating to adjustments upon changes
in stock, no amendment shall be effective unless approved by the stockholders of
the Company within twelve (12) months before or after the adoption of the
amendment, where the amendment will:

         (i)    Increase the number of shares reserved for rights under the
     Plan;

         (ii)   Modify the provisions as to eligibility for participation in the
     Plan (to the extent such modification requires stockholder approval in
     order for the Plan to obtain employee stock purchase plan treatment under
     Section 423 of the Code; or

                                       7
<PAGE>

         (iii)  Modify the Plan in any other way if such modification requires
     stockholder approval in order for the Plan to obtain employee stock
     purchase plan treatment under Section 423 of the Code.

It is expressly contemplated that the Board may amend the Plan in any respect
the Board deems necessary or advisable to provide eligible employees with the
maximum benefits provided or to be provided under the provisions of the Code and
the regulations promulgated thereunder relating to employee stock purchase plans
and/or to bring the Plan and/or rights granted under it into compliance
therewith.

     (b) Rights and obligations under any rights granted before amendment of the
Plan shall not be impaired by any amendment of the Plan, except with the consent
of the person to whom such rights were granted, or except as necessary to comply
with any laws or governmental regulations, or except as necessary to ensure that
the Plan and/or rights granted under the Plan comply with the requirements of
Section 423 of the Code.

14.  Designation of Beneficiary.

     (a) A participant may file a written designation of a beneficiary who is to
receive any shares and cash, if any, from the participant's account under the
Plan in the event of such participant's death subsequent to the end of an
Offering but prior to delivery to the participant of such shares and cash.  In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under the Plan in the event
of such participant's death during an Offering.

     (b) Such designation of beneficiary may be changed by the participant at
any time by written notice.  In the event of the death of a participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such participant's death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its sole discretion, may deliver such shares
and/or cash to the spouse or to any one or more dependents or relatives of the
participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

15.  Termination or Suspension of the Plan.

     (a) The Board in its discretion, may suspend or terminate the Plan at any
time.  No rights may be granted under the Plan while the Plan is suspended or
after it is terminated.

     (b) Rights and obligations under any rights granted while the Plan is in
effect shall not be impaired by suspension or termination of the Plan, except as
expressly provided in the Plan or with the consent of the person to whom such
rights were granted, or except as necessary to comply with any laws or
governmental regulation, or except as necessary to ensure that the Plan and/or
rights granted under the Plan comply with the requirements of Section 423 of the
Code.

16.  Effective Date of Plan.

                                       8
<PAGE>

     The Plan shall become effective on the same day that the Company's initial
public offering of shares of common stock becomes effective (the "Effective
Date"), but no rights granted under the Plan shall be exercised unless and until
the Plan has been approved by the stockholders of the Company within twelve (12)
months before or after the date the Plan is adopted by the Board or the
Committee, which date may be prior to the Effective Date.

               of such election within the above time period shall be deemed to
               constitute an election by the Bank not to extend the Revolving
               Credit Period.

         d.    Section 2.08(c) of the Credit Agreement is hereby deleted in its
      entirety and the following new Section 2.08(c) is substituted therefor:

                   ----------
               on June 30, 2001 shall be payable in consecutive monthly payments
               on the first day of each month, beginning August 1, 2001, equal
               to the quotient of the amount of such unpaid principal balance on
               June 30, 2001 divided by 84; provided, however, that the entire
               unpaid principal balance of the Term Loans and all accrued
               interest thereon shall be due and payable in full on July 1,
               2008.
