                             ARDENT SOFTWARE, INC.

                          EMPLOYEE STOCK PURCHASE PLAN

                 Amended and Restated effective October 7, 1997


l.     PURPOSE. The purpose of this Employee Stock Purchase Plan (the "Plan") is
       to provide employees of Ardent Software, Inc. (the "Company"), and its
       subsidiaries, who wish to become stockholders of the Company an
       opportunity to purchase Common Stock of the Company (the "Shares"). The
       Plan is intended to qualify as an "employee stock purchase plan" within
       the meaning of Section 423 of the Internal Revenue Code of 1986, as
       amended (the "Code").

2.     ELIGIBLE EMPLOYEES. Subject to provisions of Sections 7, 8 and 9 below,
       any individual who is in the full-time employment (as defined below) of
       the Company, or any of its subsidiaries (as defined in Section 424(f) of
       the Code) the employees of which are designated by the Board of Directors
       as eligible to participate in the Plan, is eligible to participate in any
       Offering of Shares (as defined in Section 3 below) made by the Company
       hereunder. Full-time employment shall include all employees whose
       customary employment is:

       (a)    in excess of 20 hours per week; and

       (b)    more than five months in the relevant calendar year.

3.     OFFERING DATES. From time to time the Company, by action of the Board of
       Directors, will grant rights to purchase Shares to employees eligible to
       participate in the Plan pursuant to one or more offerings (each of which
       is an "Offering") on a date or series of dates (each of which is an
       "Offering Date") designated for this purpose by the Board of Directors.

4.     PRICES. The Price per share for each grant of rights hereunder shall be
       the lesser of:

       (a)    eighty-five percent (85%) of the fair market value of a Share on
              the Offering Date on which such right was granted; or

       (b)    eighty-five percent (85%) of the fair market value of a Share on
              the date such right is exercised.

       At its discretion, the Board of Directors may determine a higher price
       for a grant of rights.

5.     EXERCISE OF RIGHTS AND METHOD OF PAYMENT.

       (a)    Rights granted under the Plan will be exercisable periodically on
              specified dates as determined by the Board of Directors.

       (b)    The method of payment for Shares purchased upon exercise or rights
              granted hereunder shall be through regular payroll deductions or
              by lump sum cash payment, or both, as determined by the Board of
              Directors; provided, however, that payment through regular payroll
              deductions may in no event commence before the date on which a
              prospectus with respect to the Offering of the Shares covered by
              the Plan is provided to each participating employee. No interest
              shall be paid upon payroll deductions unless specifically provided
              for by the Board of Directors.

       (c)    Any payments received by the Company from a participating employee
              and not utilized for the purchase of Shares upon exercise of a
              right granted hereunder shall be promptly returned to such
              employee by the Company after termination of the right to which
              the payment relates.

6.     TERM OF RIGHTS. Rights granted on any Offering Date shall be exercisable
       upon the expiration of such period ("Offering Period") as shall be
       determined by the Board of Directors when it authorizes the Offering,
       provided that such Offering Period shall in no event be longer than
       twenty-seven (27) months.

7.     SHARES SUBJECT TO THE PLAN. No more than 700,000 Shares may be sold
       pursuant to rights granted under the Plan. Appropriate adjustments in the
       above figure, in the number of Shares covered by outstanding rights
       granted hereunder, in the exercise price of the rights and in the maximum
       number of Shares which an employee may purchase (pursuant to Section 9
       below) shall be made to give effect to any mergers, consolidations,
       reorganizations, recapitalizations, stock splits, stock dividends or
       other relevant changes in the capitalization of the Company occurring
       after the effective date of the Plan, provided that no fractional Shares
       shall be subject to a right and each right shall be adjusted downward to
       the nearest full Share. Any agreement of merger or consolidation will
       include provisions for protection of the then existing rights of
       participating employees under the Plan. Either authorized and unissued
       Shares or issued Shares heretofore or hereafter reacquired by the Company
       may be made subject to rights under the Plan. If for any reason any right
       under the Plan terminates in whole or in part, Shares subject to such
       terminated right may again be subjected to a right under the Plan.

8.     LIMITATIONS ON GRANTS.

       (a)    No employee shall be granted a right hereunder if such employee,
              immediately after the right is granted, would own stock or rights
              to purchase 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 subsidiary, computed in accordance with
              Sections 423(b)(3) and 424(d) of the Code.

       (b)    No employee shall be granted a right which permits his right to
              purchase shares under all employee stock purchase plans of the
              Company and its subsidiaries to accrue at a rate which exceeds
              twenty-five thousand dollars ($25,000) (or such other maximum as
              may be prescribed from time to time by the Code) of the fair
              market value of such Shares (determined at the time such right is
              granted) for each calendar year in which such right is outstanding
              at any time in accordance with the provisions of Section 423(b)(8)
              of the Code.

       (c)    No right granted to any participating employee under a single
              Offering shall cover more shares than may be purchased at an
              exercise price equal to that percentage of the employee's annual
              rate of compensation on the date the employee elects to
              participate in the Offering as determined by the Board of
              Directors from time to time.

9.     LIMIT ON PARTICIPATION. Participation in an Offering shall be limited to
       eligible employees who elect to participate in such Offering in the
       manner, and within the time limitation, established by the Board of
       Directors when it authorizes the offering.

10.    CANCELLATION OF ELECTION TO PARTICIPATE. An employee who has elected to
       participate in an Offering may, unless the employee has waived this
       cancellation right at the time of such election in a manner established
       by the Board of Directors, cancel such election as to all (but not part)
       of the rights granted under such Offering by giving written notice of
       such cancellation to the Company before the expiration of the Offering
       Period. Any amounts paid by the employee for the Shares or withheld for
       the purchase of Shares from the employee's compensation through payroll
       deductions shall be paid to the employee, without interest, upon such
       cancellation.

11.    TERMINATION OF EMPLOYMENT. Upon termination of employment for any reason,
       including the death of the employee, before the date on which any rights
       granted under the Plan are exercisable, all such rights shall immediately
       terminate and amounts paid by the employee for the Shares or withheld for
       the purchase of Shares from the employee's compensation through payroll
       deductions shall be paid to the employee or to the employee's estate,
       without interest.

12.    EMPLOYEE'S RIGHTS AS STOCKHOLDER. No participating employee shall have
       any rights as a stockholder in the Shares covered by a right granted
       hereunder until 


                                       3

       corresponding Shares and the Share certificate is actually issued.

13.    RIGHTS NOT TRANSFERABLE. Rights under the Plan are not assignable or
       transferable by a participating employee and are exercisable only by the
       employee. 14. AMENDMENTS TO OR DISCONTINUANCE OF THE PLAN. The Board of
       Directors may at any time terminate or amend this Plan without notice and
       without further action on the part of stockholders of the Company,
       provided:

(a)    that no such termination or amendment shall adversely affect the then
       existing rights of any participating employee;

(b)    that any such amendment which:

       (i)    increases the number of Shares subject to the Plan (subject to the
              provisions of Section 7);

       (ii)   changes the class of persons eligible to participate under the
              Plan; or

       (iii)  materially increases the benefits accruing to participants under
              the Plan shall be subject to approval of the stockholders of the
              Company.

15.    EFFECTIVE DATE AND APPROVALS. The Plan was adopted by the Board of
       Directors on March 25, 1992 to become effective as of said date and
       approved by the stockholders of the Company on April 17, 1992. The
       Company's obligation to offer, sell and deliver its Shares under the Plan
       is subject to the approval of any governmental authority required in
       connection with the authorized issuance or sale of such Shares and is
       further subject to the Company receiving the opinion of its counsel that
       all applicable securities laws have been complied with.

16.    TERM OF PLAN. No rights shall be granted under the Plan after March 25,

17.    ADMINISTRATION OF THE PLAN. The Board of Directors or any committee or
       persons to whom it delegates its authority (the "Administrator") shall
       administer, interpret and apply all provisions of the Plan. The
       Administrator may waive such provisions of the Plan as it deems necessary
       to meet special circumstances not anticipated or covered expressly by the
       Plan. Nothing contained in this Section shall be deemed to authorize the
       Administrator to alter or administer the provisions of the Plan in a
       manner inconsistent with the provisions of Section 423 of the Code.
