ITEM 2.       Acquisition or Disposition of Assets

         (a) As of July 31, 1996, the Registrant entered into and consummated
the transactions contemplated by an agreement and plan of reorganization to
acquire all of the outstanding capital stock of Serif Inc, a Delaware
corporation ("Serif Inc.") with its principal office located in Nashua, New
Hampshire, from the stockholders thereof, and an agreement and plan of
reorganization to acquire all of the outstanding capital stock of Serif (Europe)
Limited, an English limited company ("Serif Limited"; and together with Serif
Inc., collectively referred to herein as "Serif"), with its principal office
located in Nottingham, England, from the stockholders thereof. The Registrant
issued an aggregate of 1,000,000 shares of its authorized and unissued common
stock in connection with these agreements, one-third of which is being held in
escrow until May 1, 1998 in respect of possible claims for breaches of
representations and warranties.

              (b) Serif's facilities were used by it in the development,
warehousing, marketing and sales of desktop publishing computer software
products. The Registrant will continue such operations under leases thereof,
except that all operations at the Nashua, New Hampshire facility other than
telephone sales are expected to be transferred to the Registrant's New Jersey
facility.

ITEM 5.       Other Events

         On July 23, 1996, Richard Bergman resigned as a director and as Vice
President of product development of the Registrant. Gwyn Jones, the former

Executive Vice President of product development. On July 24, 1996, Joseph
Cirillo, President of H. Betti Industries, Inc. and Mark E. Leininger, the
Registrant's Vice President-Finance, were elected as directors of the Registrant
in classes II and III, respectively.

              (a) Financial Statements of business acquired. Since it is
impractical at this time to provide the required audited financial statements of
Serif Inc. and Serif (Europe) Limited as of December 31, 1995 and 1994 and for
the years then ended and unaudited financial statements of such companies for
the six months ended June 30, 1996 and 1995, the Registrant will file such
required financial statements on Form 8-K/A as soon as practicable, but not
later than sixty days after the required filing date of this report.

              (b) Pro forma financial information. Since it is impractical to

complete copies of all of the contracts, agreements and other documents listed
in Schedule 4.15 hereto and all amendments thereto and any waivers granted
thereunder (the "Scheduled Contracts"). Except as specifically set forth on
Schedule 4.15, the exchange of the Stock with Allegro and the consummation of
the other transactions contemplated by this Agreement are not a violation of or
grounds for the modification or cancellation of any of the Scheduled Contracts
or for the imposition of any penalty or security interests thereunder. Except as

business in another jurisdiction.

                  (d) Except as described in Schedule 4.15 hereto, all Scheduled
Contracts described in Schedule 4.15 are valid and effective in accordance with
their respective terms, and there is not, under any of such documents or
agreements or any obligation, or covenant or condition contained therein, any
existing default by the Company, or to the knowledge of the Company or the
Stockholders, by any other party, or any event which with notice, lapse of time,
or both, would constitute a default and which would have a material adverse
effect on the continued operation of the Company or its business.

maintained by the Company or an Affiliate or to which the Company or an
Affiliate contributes or is required to contribute, including any multiemployer
employee welfare benefit plan, on behalf of officers and employees of the
Company or an Affiliate (such multiemployer and other employee welfare benefit
plans being hereinafter collectively referred to as the "Welfare Benefit
Plans"). With respect to each Welfare Benefit Plan, all contributions or

                  (b) Schedule 4.21 hereto sets forth a true and complete list

maintained by the Company or an Affiliate or to which the Company or an
Affiliate contributes or is required to contribute, including any multiemployer

Company or an Affiliate (such multiemployer and other employee pension benefit
plans being hereinafter collectively referred to as the "Pension Benefit
Plans"). No Pension Benefit Plan is a "defined benefit plan" (as defined in
Section 3(35) of ERISA). With respect to each Pension Benefit Plan including an
"individual account plan" (as defined in Section 3(34) of ERISA), all
contributions due by or attributable to the period ending on the Closing Date
have been made or will be made prior to the Closing Date.

                  (c) Each Pension Benefit Plan, each Welfare Benefit Plan and
each related trust agreement and annuity contract and insurance policy (and any
other funding instruments) complies currently, and has complied in the past,
both as to form and operation, with the provisions of (i) the Code in order to
be tax qualified under Section 401(a) or 403(a) of the Code; (ii) ERISA; and
(iii) all other applicable laws, rules and regulations; all necessary government
approvals for the Pension Benefit Plans have been obtained; and favorable

                                       13
<PAGE>   14
have been received from the Internal Revenue Service and no event has occurred
or condition exists which would adversely affect such determination.

                  (d) Each Welfare Benefit Plan and each Pension Benefit Plan
has been administered to date in material compliance with the requirements of
the Code, ERISA and all other applicable laws and all reports required by any
government agency with respect to each Welfare Benefit Plan and each Pension
Benefit Plan have been timely filed. Future compliance with the requirements of
the Code, ERISA or any other applicable laws as in effect on the date of the
Closing or any collective bargaining agreements to which the Company or an
Affiliate is a party will not result in any increase in the rate of benefit
accrual under any Pension Benefit Plan.

                  (e) Neither the Company, nor any Affiliate, nor any plan
fiduciary of any Welfare Benefit Plan or Pension Benefit Plan has engaged in any
transaction in violation of Section 406 of ERISA or any "prohibited transaction"
(as described in Section 4975(c) of the Code).

                  (f) Schedule 4.21 lists each deferred compensation plan, bonus
plan, stock option plan, employee stock purchase plan and any other employee
benefit plan, agreement, arrangement or commitment not required under a previous
subsection to be listed on Schedule 4.21 maintained by the Company or an
Affiliate with respect to the compensation of any of their employees.

                  (g) No liability to the PBGC has been incurred by the Company
or other trade or business under common control with the Company (as determined
under Sections 414(b), 414(c), 414(m) or 414(o) of the Code) ("Common Control
Entity") on account of any termination of an employee pension benefit plan
subject to Title IV of ERISA. No filing has been made by the Company (or any
Common Control Entity) with the PBGC (and no proceeding has been commenced by
the PBGC) to terminate any employee pension benefit plan subject to Title IV of
ERISA maintained, or wholly or partially funded, by the Company (or any Common
Control Entity). Neither the Company nor any Common Control Entity has (i)
ceased operations at a facility so as to become subject to the provisions of
Section 4062(e) of ERISA, (ii) withdrawn as a substantial employer so as to
become subject to the provisions of Section 4063 of ERISA, (iii) ceased making
contributions on or before the date of the Closing to any employee pension
benefit plan subject to Section 4064(a) of ERISA to which the Company (or any
Common Control Entity) made contributions during the five years prior to the
date of the Closing, or (iv) made a complete or partial withdrawal (as each is
defined in Sections 4203 and 4205, respectively, of ERISA) or a reduction in
contribution base units which if sustained for three years would constitute a
partial withdrawal under Section 4205 of ERISA, from a multiemployer plan (as
defined in Section 3(37) of ERISA) so as to incur withdrawal liability as
defined in Section 4201 of ERISA (without regard to subsequent reduction or
waiver of such liability under Section 4207 or 4208 of ERISA). Neither the
Company, any Affiliate nor any Common Control Entity, including both single
employer and multi-employer pension plans, has engaged in a transaction designed
to avoid or evade liability until Title IV of ERISA within the five years
preceding the Closing Date.

                  (h) There are no actions, suits or claims (other than routine
claims for benefits) pending or which could reasonably be expected to be
asserted against any Pension Benefit Plan or Welfare Benefit Plan; there are no
civil or criminal actions pending or threatened against any fiduciary, Pension
Benefit Plan or Welfare Benefit Plan with respect to the plan; and no Pension
Benefit Plan or

                                       14
<PAGE>   15
Welfare Benefit Plan is the direct or indirect subject of any audit,
investigation or examination by any governmental or quasi governmental agency,
and no such completed audit, investigation or examination, if any, has resulted
in the imposition of any fine or penalty on any person.

<PAGE>   29
         8.2.     Non-Exclusivity.

                  Nothing herein contained shall be construed as prohibiting the
Company or Allegro from pursuing any other remedies available to it for such
violation, including but not limited to any injunctive or other equitable relief
or the recovery of damages from the Stockholders.

         8.3.     Equitable Relief.

                  The Covenantees acknowledge that the covenants contained in
this Section 8 are fair and reasonable in order to protect the Company's and
Allegro's business and were a material and necessary inducement for Allegro to
agree to the transactions contemplated hereby. The Covenantees further
acknowledge that they have realized significant monetary benefit from these
transactions, that any remedy at law for any breach or threatened or attempted
breach of the covenants contained in this Section 8 may be inadequate and that
the violation of any of the covenants contained in this Section 8 will cause
irreparable and continuing damage to Allegro and the Company. Accordingly, the
Company or Allegro shall be entitled to specific performance or any other mode
of injunctive and/or other equitable relief to enforce their rights hereunder,
including without limitation an order restraining any further violation of such
covenants, or any other relief a court might award, without the necessity of
showing any actual damage or irreparable harm or the posting of any bond or
furnishing of other security, and that such injunctive relief shall be
cumulative and in addition to any other rights or remedies to which Allegro may
be entitled. The covenants in this Section 8 shall run in favor of Allegro, the
Company and their successors and assigns. In addition, the Covenantees agree to
pay Allegro and Company the costs they incur, including reasonable attorneys'
fees and expenses, in bringing and prosecuting any proceeding to enforce the
terms of this Agreement.

         8.4.     Severability.

                  In case any one or more of the terms or provisions contained
in this Section 8 shall for any reason be held invalid, illegal or
unenforceable, such invalidity, illegality or unenforceability shall not affect
any other terms or provisions hereof, but such term or provision shall be deemed
modified or deleted as or to the extent required by applicable law, and such
modification or deletion shall not affect the validity of the other terms or
provisions of this Section 8. In addition, if any one or more of the
restrictions contained in this Section 8 shall for any reason be held to be
unreasonable with regard to time, duration, geographic scope or activity, the
parties contemplate and hereby agree that such restriction shall be modified and
shall be enforced to the full extent compatible with applicable law. The parties
hereto intend that the covenants contained in this Section 8 shall be deemed a
series of separate covenants for each country, state, county and city. If, in
any judicial proceeding, a court shall refuse to enforce all the separate
covenants deemed included in this Section 8 because, taken together, they cover
too extensive a geographic area, the parties intend that those of such covenants
(taken in order of the cities, counties, states and countries therein which are
lease populous) which if eliminated would permit the remaining separate
covenants to be enforced in such proceeding shall, for the purpose of such
proceeding, be deemed eliminated from the provisions of this Section 8.

           11.1     Indemnification.

                    (a) The Stockholders, jointly and severally (and the
Company, only if the transactions contemplated hereby are not consummated), will
indemnify Allegro against, and hold Allegro harmless from, any and all
liability, damage, deficiency, loss, cost or expense (including reasonable
attorneys' fees) (individually, any one such item being called a "Loss" and more
than one such item, "Losses"), that are based upon or that arise out of (i) any
misrepresentation or breach of any representation, warranty, covenant or
agreement made by the Stockholders or the Company herein or in any certificate
delivered pursuant hereto; and, (ii) to the extent exceeding $40,000 and not
reflected as a liability on the Company's accounts payable aging included as
part of Schedule 4.8 (A) the expiration of the license agreement with Adobe
(f/k/a Mastersoft) as disclosed in Schedule 4.15 in part II thereof; (B) the
expiration of the license agreement with Pantone as disclosed in Schedule 4.15
in part II thereof; (C) the use by the Company of software bearing the name or
trade style "Twain" as set forth in Schedule 4.16 as item 6 of the final
paragraph thereof; (D) the use by the Company of software bearing the name and
trade style "GIF" as set forth in Schedule 4.16 as item 7 of the final paragraph
thereof; and (E) the use by the Company of technology obtained from Andover
Advanced Technology but not properly covered by a license as disclosed in
Schedule 4.16. No cost or expense shall be included as part of any Loss if and
to the extent that the Loss is paid or accrued after the date of such aging as
and for a royalty or a license fee in accordance with the regular royalties and
fees disclosed for such matter in a Schedule to this Agreement. Royalties
incurred after the date hereof for the use of Twain and GIF or any alternative
technology replacing either of them shall not be included as part of any Loss.

                    (b) Allegro will indemnify the Stockholders (and the
Company, only if the transactions contemplated hereby are not consummated)
against, and hold the Stockholders harmless from, any and all Losses that are
based upon or that arise out of any misrepresentation or breach of any
representation, warranty, covenant or agreement made by Allegro herein or in any
certificate delivered pursuant hereto.

                    (c) Each party entitled to indemnification under this
Agreement (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party (at its expense) to assume the
defense of any claim or any litigation resulting therefrom; provided that
counsel for the Indemnifying Party, who shall conduct the defense of such claim
or litigation, shall be reasonably satisfactory to the Indemnified Party, and
the Indemnified Party may participate in such defense, but only at such
Indemnified Party's expense; and provided, further, that the omission by any
Indemnified Party to give notice as provided herein shall not

                                       33
<PAGE>   34
relieve the Indemnifying Party of its indemnification obligations under this
Agreement except and only to the extent that the omission results in a failure
of actual notice to the Indemnifying Party and such Indemnifying Party is
damaged as a result of the failure to give notice. No Indemnifying Party, in the
defense of any such claim or litigation, shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
with respect to such claim or litigation. In the event that the Indemnifying
Party does not accept the defense of any matter as above provided, or after so
accepting fails to diligently prosecute such defense, the Indemnified Party
shall have the full right to defend against any such claim or demand, at the
expense of the Indemnifying Party, and shall be entitled to settle or agree to
pay in full such claim or demand, in its sole discretion. In any event, the
Company, the Stockholders and Allegro shall cooperate in the defense of such
action and the records of each shall be available to the other with respect to
such defense.

           11.2.    Time and Manner of Claims; Survival.

           Allegro or the Company and each Stockholder shall be liable for
damages arising from its or his misrepresentations or breaches of its or his
representations, warranties or covenants hereunder only pursuant to the terms of
this Section 11 and other than with respect to Sections 4.2 and 4.4, only to the
extent that notice of a claim therefor is asserted by the other in writing and
delivered prior to May 1, 1998. The Company and each Stockholder shall be liable
for damages arising from its or his misrepresentations or breaches of its or his
representations and warranties pursuant to Sections 4.2 and 4.4 at any time
whatsoever. Any notice of a claim by reason of any of the representations,
warranties or covenants contained in this Agreement shall state the
representation, warranty or covenant with respect to which the claim is asserted
and the amount of liability asserted against the other party by reason of the
claim. The representations, warranties, covenants, agreements and indemnities
contained in this Agreement shall survive the execution and delivery of this
Agreement, any examination by or on behalf of such parties, and the completion
of the transactions contemplated herein.

           11.3     Limitation on Claims.

           Notwithstanding anything contained in this Agreement to the contrary,
(i) neither the Company and the Stockholders, on one hand, nor Allegro, on the
other hand, shall be entitled to claim for the breach of any representation,
warranty, covenant or agreement set forth herein (other than with respect to a
breach of Section 4.2 or 4.4 or Section 11.1(a)(ii)) except to the extent that
the aggregate amount of its present claims in respect of (a) such breaches, and
(b) all prior claims for breaches of representations, warranties covenants and
agreements hereunder, exceeds an aggregate of $25,000, at which time the
claiming party shall be entitled to claim the full amount of its damages for all
breaches by the other parties hereto of such representations, warranties,
covenants and agreements to the extent such claims exceed $25,000; (ii) the
liability hereunder of the Stockholders other than for any misrepresentation or
breach of Section 4.2 or 4.4 hereof (the liability for which shall be unlimited)
shall not exceed an amount equal to the product of (A) the number of shares of
Escrow Stock issued to such Stockholder hereunder and deposited with the Escrow
Agent under the Escrow Agreement, times (B) the last reported sale price of the
Allegro Common Stock on the date on which such liability is determined (or May
1, 1998 in respect of claims delivered under Section 12.2 after that date), and,
except with respect to claims relating to Section 4.2 or 4.4 arising after the
Escrow Stock is released from escrow pursuant to the Escrow

                                       34
<PAGE>   35
Agreement, shall be satisfied exclusively from the Escrow Stock; and (iii) the
Stockholders and the Company shall not be liable to Allegro under this Section 
11 for Losses arising from the inaccuracy or breach of any representation or
warranty contained in Section 4 hereof to the extent such inaccuracy or breach
is caused by events beyond the control of the Company or the Stockholders which
occur after the date hereof and prior to the Closing Date.

           12.1.    Consent to Jurisdiction and Waivers.

or proceeding. Allegro, the Company and the Stockholders further irrevocably
consent to the service of any complaint, summons, notice or other process
relating to any such action or proceeding by delivery thereof to it by hand or
by any other manner provided for in Section 12.3. Allegro and the Stockholders
hereby expressly and irrevocably waive any claim or defense in any such action
or proceeding based on any alleged lack of personal jurisdiction, improper venue
or forum non convenient or any similar basis. Nothing in this Section 12.1 shall
affect or impair in any manner or to any extent the right of Allegro to commence
legal proceedings or otherwise proceed against the Company or the Stockholders
in any jurisdiction or to serve process in any manner permitted by law.

           12.2.    Severability.

any provision of the covenant not to compete, shall be held or deemed to be or
shall, in fact, be inoperative or unenforceable as applied in any particular
case because it conflicts with any other provision or provisions hereof or any
constitution or statute or rule of public policy, or for any other reason, such
circumstances shall not have the effect of rendering the provision in question
inoperative or unenforceable in any other case or circumstance, or of rendering
any other provision or provisions herein contained invalid, inoperative, or
unenforceable to any extent whatever. The invalidity of any one or more phrases,
sentences, clauses, sections, or subsections of this Agreement shall not affect
the remaining portions of this Agreement.

(a) During the period commencing on the Closing date and ending on the fourth
anniversary of the Closing Date (subject to Section 8.2 below, the "Restricted
Period"), Gwyn Jones, Peter Beedham and James Bryce (the "Covenantees") shall
not, without the written consent of Allegro, directly or indirectly,

(i) become associated with, render services to, invest in, represent, advise or
otherwise participate in as an officer, employee, director, stockholder,
partner, promoter, agent of, consultant for or otherwise, any business which is
conducted in any of the jurisdictions in which the Company's or Allegro's
business is conducted and which is engaged in the business of developing,
marketing, licensing or selling desktop publishing and/or publication computer
software;

(ii) for the Covenantees's own account or for the account of any other person or
entity (A) interfere with the Company's or Allegro's relationship with any of
its suppliers, customers, licensors, licensees, independent contractors,
representatives or agents or (B) contact, telephone, meet, solicit or transact

<PAGE>   24
                                     - 24 -

(iii) employ or otherwise engage, or solicit, entice or induce on behalf of any
Covenantee or any other person or entity, the services, retention or employment

stockholder, independent contractor, sales representative, consultant to or
agent of the Company or Allegro within one year of the date of such offer or
solicitation.

(b) The provisions of this Section 8 shall survive the termination of this
Agreement.

8.2  Non-Exclusivity

Nothing herein contained shall be construed as prohibiting the Company or
Allegro from pursuing any other remedies available to it for any breach,
including but not limited to any injunctive or other equitable relief or the
recovery of damages from the Stockholders.

8.3  Equitable Relief

The Covenantees acknowledge that the covenants contained in this Section 8 are
fair and reasonable in order to protect the Company's and Allegro's business and
were a material and necessary inducement for Allegro to agree to the
transactions contemplated hereby. The Covenantees further acknowledge that they
have realized significant monetary benefit from these transactions, that any
remedy at law for any breach or threatened or attempted breach of the covenants
contained in this Section 8 may be inadequate and that the breach of any of the
covenants contained in this Section 8 will cause irreparable and continuing
damage to Allegro and the Company. Accordingly, the Company or Allegro shall be
entitled to specific performance or any other mode of injunctive and/or other
equitable relief to enforce their rights hereunder, including without limitation
an order restraining any further breach of such covenants, or any other relief a
court might award, without the necessity of showing any actual damage or
irreparable harm or the posting of any bond or furnishing of other security, and
that such injunctive relief shall be cumulative and in addition to any other
rights or remedies to which Allegro may be entitled. The covenants in this
Section 8 shall run in favour of Allegro, the Company and their successors and
assigns. In addition, the Covenantees agree to pay Allegro and Company the costs
they incur, including reasonable attorneys' fees and expenses, in bringing and
prosecuting any proceeding to enforce the terms of this Agreement.

8.4  Severability

In case any one or more of the terms or provisions contained in this Section 8
shall for any reason be held invalid, illegal or unenforceable, such invalidity,
illegality or unenforceability shall not affect any other terms or provisions
hereof, but such term or provision shall be deemed modified or deleted as or to
the extent required by applicable law, and such modification or deletion shall
not affect the validity of the other terms or provisions of this Section 8. In
addition, if any one or more of the restrictions contained in this Section 8
shall for any reason be held to be unreasonable with regard to time, duration,
geographic scope or activity, the parties contemplate and hereby agree that such
restriction shall be modified and shall be enforced to the full extent
compatible with applicable law. The parties hereto intend that the covenants
contained in this Section 8 shall be deemed a series of separate covenants for
each country, state, county and city. If, in any judicial proceeding, a court
shall refuse to enforce all the separate covenants deemed included in this
Section 8 because, taken together, they cover too extensive a geographic area,
the parties intend that those of such covenants (taken in order of the cities,
counties, states and countries therein which are lease populous) which if
eliminated would permit the remaining separate covenants to be enforced in such
proceeding shall, for the purpose of such proceeding, be deemed eliminated from
the
<PAGE>   25
                                     - 25 -

provisions of this Section 8. Each of the covenants contained in Section 8 is a
separate undertaking by each covenantee in relation to himself and his interests
and shall be enforceable by Allegro separately and independently of its right to
enforce any one or more of the other covenants contained in Section 8.

9.  RESTRICTIVE TRADE PRACTICES ACT 1976

Where this Agreement is or forms part of an agreement which is subject to
registration under the Restrictive Trade Practices Act 1976 ("RTPA"), no
restriction accepted or information provision made under that agreement shall
come into effect until the day after particulars of the agreement have been
furnished to the Director General of Fair Trading under section 24 RTPA. If any
party shall wish to furnish such particulars, the other parties will render such
co-operation and undertake such action as may reasonably be required of them for
such purpose so that particulars may be furnished as soon as practicable
following the signature of this Agreement and each of the parties consents to
the disclosure of all information so furnished. In this clause the words and
terms "agreement" and "subject to registration" shall have the meanings
respectively given to them by the RTPA and the reference to "restrictions
accepted" or "information provision made" under the agreement shall be to
restrictions accepted or information provisions made by virtue of which the
agreement is subject to registration.

                                LOCK-UP AGREEMENT


              This AGREEMENT (the "Agreement") is made as of the 31st day of
July, 1996, between the undersigned former stockholder (the "Undersigned") of
Serif, Inc. , a Delaware corporation (the "Company") and Allegro New Media,
Inc., a Delaware corporation ("Allegro").

              NOW, THEREFORE, for good and valuable consideration, including the
agreements by certain other former stockholders of the Company to be similarly
bound, the sufficiency and receipt of which consideration are hereby
acknowledged, the Undersigned agrees as follows:

              1. BACKGROUND. The Undersigned acknowledges that Allegro has
required, and the Company has agreed to assist Allegro in obtaining, agreements
from all former stockholders of the Company, to refrain from selling certain
quantities of securities of Allegro for a period of up to 24 months following
the completion of Allegro's acquisition (the "Acquisition") of all of the
capital stock of the Company pursuant to the Stock Purchase Agreement dated the
date hereof among Allegro, the Company, Serif (Europe) Limited and the other
stockholders of the Company and Serif (Europe) Limited. To induce Allegro to
proceed with the Acquisition and other stockholders of the Company to make
similar agreements, the Undersigned has entered into this Agreement.

              2. RESTRICTION. The Undersigned hereby agrees that from the
closing of the Acquisition to and including a date 24 months thereafter, the
Undersigned will not directly or indirectly, issue, offer to sell, grant an
option for the sale of, assign, transfer, pledge, hypothecate or otherwise
encumber or dispose of any shares of common stock, par value $.001 per share
(the "Common Stock") or securities convertible into, exercisable or exchangeable
for or evidencing any right to purchase or subscribe for any shares of Common
Stock (either pursuant to Rule 144 under the Securities Act of 1933, as amended,
or otherwise) or dispose of any beneficial interest therein without the prior
written consent of the President of Allegro, except that the Undersigned may
sell in brokerage transactions in the aggregate (a) up to ten percent (10%) of
the shares of Common Stock owned beneficially or of record (the "Stock") during
the period from six (6) months after the date hereof (the "Closing Date") until
twelve (12) months thereafter, (b) an additional ten (10%) of the Stock during
the period from twelve (12) months after the Closing Date until eighteen (18)
months thereafter, and (c) an additional ten percent (10%) during the period
from eighteen (18) months after the Closing Date until twenty-four (24) months
thereafter. The Undersigned further agrees that Allegro is authorized to place
"stop orders" on its books to prevent any transfer of securities of Allegro by
the Undersigned in violation of this Agreement.

              3. RELIANCE BY THE COMPANY, UNDERWRITERS AND OTHER STOCKHOLDERS.
The Undersigned acknowledges that Allegro is relying upon the agreements of the
Undersigned contained herein, and that the failure of the Undersigned to perform
the agreements contained herein
<PAGE>   2
could have a detrimental effect upon any proposed offering. Accordingly, the
Undersigned understands and agrees that the Undersigned's agreements herein are
irrevocable.

              4.      MISCELLANEOUS.

                      (a) At any time, and from time to time, after the signing
of this Agreement, the Undersigned will execute such additional instruments and
take such action as may be reasonably requested by Allegro to carry out the
intent and purposes of this Agreement.

                      (b) This Agreement shall be governed, construed and
enforced in accordance with the laws of the State of New York, except to the
extent that the securities laws of the State in which the Undersigned resides
and federal securities laws may apply.

                      (c) This Agreement contains the entire agreement of the
Undersigned with respect to the subject matter hereof.

                      (d) This Agreement shall be binding upon the Undersigned,
his legal representatives, successors and assigns.

                      IN WITNESS WHEREOF, and intending to be legally bound

                                                                   EXHIBIT 10.31


                          REGISTRATION RIGHTS AGREEMENT

                  This Agreement (this "Agreement") is made and entered into as
of July 31, 1996, by and between Allegro New Media, Inc., a Delaware corporation
(the "Company"), and each of the persons or entities executing this Agreement
(collectively referred to herein as the "Holders").

                  The parties hereby agree as follows:

                  1.       Definitions.

                          (a) Registerable Securities. The terms "Registerable
Securities" and "Restricted Securities" shall mean the Company's common stock,
par value $.001 per share (the "Common Stock"), which is acquired by the Holders
pursuant to the terms of the Stock Purchase Agreement (the "Stock Purchase
Agreement") dated the date hereof by and among the Company, Serif, Inc., a
Delaware corporation, Serif (Europe) Limited, an English company and the
Holders, including in each case any shares received in connection with any stock
split, stock divided, recapitalization, reclassification or other distribution
payable or issuable in shares of Common Stock.

                          (b) Restricted Securities. For the purposes of this
Agreement, shares will cease to be Restricted Securities when (i) a registration
statement covering such Restricted Securities has been declared effective and
they have been disposed of pursuant to such effective registration statement, or
(ii) they are distributed to the public under the Securities Act of 1933, as
amended (the "Securities Act"), or (iii) they have been otherwise transferred
and the Company, in accordance with applicable law and regulations, has
delivered new certificates or other evidences of ownership for them not subject
to any stop transfer order or other restriction on transfer.

                          (c) Registerable Securities. As to any particular
shares, such shares will cease to be Registerable Securities when they cease to
be Restricted Securities.

                          (d) Stockholders Representative. For purposes of this
Agreement, Gwyn Jones.

                  2.       Piggy-Back Registration.

                          At any time, if the Company proposes to file a
registration statement under the Securities Act with respect to an offering by
the Company of any class of equity security similar to any Registerable
Securities (other than a registration statement on Form S-4 or S-8 or any
successor form or a registration statement filed solely in connection with an
exchange offer, a business combination transaction or an offering of securities
solely to the existing stockholders or employees of the Company), then the
Company shall give written notice of such proposed filing to the Stockholders
Representative at least 15 days before the anticipated filing date, and such
notice
<PAGE>   2
shall offer such holders the opportunity to register such aggregate number of
Registerable Securities as each such holder may request. The Company shall use
diligent efforts to cause the managing underwriter or underwriters of a proposed
underwritten offering to permit, within 25 days of the giving of the written
notice provided for in the immediately preceding sentence, the holders of
Registerable Securities requested to be included in the registration to include
such securities in such underwritten offering on the same terms and conditions
as any similar securities of the Company included therein. Notwithstanding
anything to the contrary in the foregoing, if the managing underwriter or
underwriters of such offering delivers a written opinion (or, in the case of an
offering not being underwritten, the Company, a resolution of its Board of
Directors certified by the President of the Company) to the Stockholders
Representative that the total amount and kind of securities which they, the
Company and any other person intend to include in such offering is such as to
materially and adversely affect the success of such offering, then the amount of
securities to be offered for the accounts of holders of Registerable Securities
and persons other than the Company shall be eliminated or reduced pro rata
(based on the amount of securities owned which carry registration rights) to the
extent necessary to reduce the total amount of securities to be included in such
offering to the amount recommended by such managing underwriter or underwriters
in its written opinion (or the Board of Directors in its resolution).

                  3.       Demand Registration.

                           (a) Right to Demand. Subject to Section 3(b) hereof,
at any time after December 7, 1996, and not earlier than 60 days after the
effective date of a registration statement in connection with which the holders
of Registrable Securities shall have had the number of Registrable Securities
subject thereto eliminated or reduced pursuant to the terms of Section 2, the
Initiating Holders (as defined below) may make a written request to the Company
for registration under the Securities Act of all or part of their Registerable
Securities (a "Demand Registration"). Within 10 days after receipt of such
request, the Company will deliver a written notice (the "Notice") of such
registration request to all holders of Registerable Securities. The Company will
include in such registration all Registerable Securities with respect to which
the Company has received written requests for inclusion therein within 15
business days after the receipt by the applicable holder of the Notice. All
requests made pursuant to this Section 3(a) will specify the aggregate amount of
the Registerable Securities to be registered and will also specify the intended
methods of disposition thereof.

                           (b) Number of Demand Registrations. The holders of
Registerable Securities shall be entitled, in the aggregate, to one Demand
Registration, the Registration Expenses of which shall be borne by the Company.
The "Initiating Holders" with respect to this Demand Registration shall mean the
Stockholders Representative. The Company shall not be deemed to have effected a
Demand Registration unless and until such Demand Registration is declared
effective.

                           (c) Priority on Demand Registrations. If a Demand
Registration is being underwritten and if the managing underwriter or
underwriters of such Demand Registration (or, in the case of a Demand
Registration not being underwritten, holders of a majority of the Registerable


                                       -2-
<PAGE>   3
Securities sought to be registered therein) advise the Company in writing that
in their opinion the number of securities proposed to be sold in such Demand
Registration exceeds the number which can be sold in such offering, the Company
will include in such registration only the number of securities that, in the
opinion of such managing underwriter or underwriters (or holders of Registrable
Securities, as the case may be), can be sold, selected pro rata (based on the
amount of securities owned which carry registration rights) among the holders of
Registrable Securities which have requested to be included in such Demand
Registration.

                           (d) Selection of Underwriters. If any Demand
Registration is an underwritten offering, the Company will select a managing
underwriter or underwriters to administer the offering, which managing
underwriter or underwriters shall be reasonably satisfactory to the holders of a
majority of the Registerable Securities to be included in such Demand
Registration.

                           (e) Notwithstanding anything in the foregoing Section
3 to the contrary, the Company shall not be obligated to effect a Demand
Registration at any time when the Company, in the good faith judgment of its
Board of Directors, reasonably believes that the filing thereof at the time
requested, or the offering of securities pursuant thereto, would be detrimental
to the interests of Company or its shareholders. The effectuation of a Demand
Registration cannot be suspended, pursuant to the provisions of the preceding
sentence, for more than 90 days after the date of the Board's determination
referenced in the preceding sentence.

                  4.       Registration Procedures.

                           The Company will, in connection with any registration
pursuant to Section 3 or 4 in which sellers of Registerable Securities are
included, as expeditiously as possible:

                           (a) prepare and file with the Securities and Exchange
Commission (the "Commission") a registration statement on any appropriate form
under the Securities Act, which form shall be available for the sale of
Registerable Securities in accordance with the intended method or methods of
distribution thereof, and use its best efforts to cause such registration
statement to become effective; provided that at least three business days before
filing with the Commission a registration statement or prospectus or any
amendments or supplements thereto, including documents incorporated by reference
after the initial filing of any registration statement, the Company will furnish
to the Stockholders Representative draft copies of such registration statement,
and, upon the request of any seller of Registerable Securities, shall continue
to provide such number of copies of such registration statement, each amendment
and supplement thereto, the prospectus included in such registration statement
(including each preliminary prospectus) and such other documents as the
Stockholders Representative may reasonably request in order to facilitate the
disposition of the Registerable Securities owned by the Holders and to change
the registration statement as it relates to any seller as reasonably requested
by the Stockholders Representative on a timely basis, and to reasonably consider
other changes to the registration statement (but not including any document
incorporated therein by reference) reasonably requested by the Stockholders
Representative on a timely basis, in light of the requirements of the Securities
Act and any other applicable laws and


                                       -3-
<PAGE>   4
regulations; and provided, further, that as to documents incorporated by
reference, the Company shall provide documents incorporated by reference
promptly upon request after the filing of such documents;

                           (b) prepare and file with the Commission such
amendments and post-effective amendments to a registration statement as may be
necessary to keep such registration statement effective for up to 9 months; and
cause the related prospectus to be supplemented by any required prospectus
supplement, and as so supplemented to be filed to the extent required pursuant
to Rule 424 under the Securities Act, during such 9 month period; and otherwise
comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such registration statement during the applicable
period in accordance with the intended methods of disposition by the sellers
thereof set forth in such registration statement or supplement to such
prospectus;

                           (c) notify the Stockholders Representative and the
managing underwriters, if any, promptly, and confirm such advice in writing, (1)
when a prospectus or any prospectus supplement or post-effective amendment has
been filed, and, with respect to a registration statement or any post-effective
amendment, when the same has become effective, (2) of any request by the
Commission for amendments or supplements to a registration statement or related
prospectus or for additional information, (3) of the issuance by the Commission
of any stop order suspending the effectiveness of a registration statement or
the initiation of any proceedings for that purpose, (4) if at any time the
representations and warranties of the Company contemplated by paragraph (j)
below cease to be true and correct, (5) of the receipt by the Company of any
notification with respect to the suspension of the qualification of any of the
Registerable Securities for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose, and (6) of the happening of any
event which makes any statement made in any registration statement, the
prospectus or any document incorporated therein by reference untrue or which
requires the making of any changes in any registration statement or prospectus
so that they will not contain any untrue statement of material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading;

                           (d) make diligent efforts to obtain the withdrawal of
any order suspending the effectiveness of a registration statement at the
earliest possible moment and to prevent the entry of such an order;

                           (e) use diligent efforts to register or qualify such
Registerable Securities under such other securities or blue sky laws of such
jurisdictions as any seller reasonably requests in writing and do any and all
other acts and things which may be necessary or advisable to enable such seller
to consummate the disposition in such jurisdictions of the Registerable
Securities owned by such seller; provided that the Company will not be required
to (i) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this paragraph (e), (ii) subject itself
to taxation in any such jurisdiction or (iii) take any action which would
subject it to general service of process in any such jurisdiction;


                                       -4-
<PAGE>   5
                           (f) make available for inspection by the Stockholders
Representative, any underwriter participating in any disposition pursuant to
such registration statement, and any attorney or accountant retained by any such
seller or underwriter (collectively, the "Inspectors"), all financial and other
records, pertinent corporate documents and properties of the Company
(collectively, the "Records") as shall be reasonably necessary to enable them to
exercise their due diligence responsibility (or establish a due diligence
defense), and cause the officers, directors and employees of the Company to
supply all information reasonably requested by any such Inspector in connection
with such registration statement. Records which the Company determines, in good
faith, to be confidential and which it notifies the Inspectors are confidential
shall not be disclosed by the Inspectors unless (i) the release of such Records
is ordered pursuant to a subpoena or other order from a court of competent
jurisdiction or (ii) the disclosure of such Records is required by any
applicable law or regulation or any governmental regulatory body with
jurisdiction over any holder of Registerable Securities. Each seller of
Registerable Securities agrees that it will, upon learning the disclosure of
such Records is sought in a court of competent jurisdiction, give notice to the
Company and allow the Company, at its expense, to undertake appropriate action
to prevent disclosure of the Records deemed confidential;

                           (g) cooperate with the selling holders of
Registerable Securities and the managing underwriters, if any, to facilitate the
timely preparation and delivery of certificates representing Registerable
Securities to be sold and not bearing any restrictive legends and enable such
Registerable Securities to be in such denominations and registered in such names
as the selling holders of Registerable Securities or any managing underwriters
may request at least two business days prior to any sale of Registerable
Securities;

                           (h) comply with all applicable rules and regulations
of the Commission and promptly make generally available to its security holders
an earnings statement covering a period of twelve months, (1) in an underwritten
offering, commencing at the end of any fiscal quarter in which Registerable
Securities are sold to underwriters, or (2) in a non-underwritten offering,
beginning with the first month of the Company's first fiscal quarter commencing
after the effective date of the registration statement, which earnings statement
in each case shall satisfy the provisions of Section 11(a) of the Securities
Act;

                           (i) provide a CUSIP number for all Registerable
Securities, not later than the effective date of the registration statement
relating to the first public offering of Registerable Securities of the Company
pursuant hereto;

                           (j) enter into such customary agreements (including
an underwriting agreement in customary form) and take all such other actions
reasonably requested by the Stockholders Representative or the managing
underwriter or underwriters in order to expedite or facilitate the disposition
of such Registerable Securities and in such connection, whether or not an
underwriting agreement is entered into and whether or not the registration is an
underwritten registration (1) make such representations and warranties, if any,
to any underwriters with respect to the registration statement, prospectus and
documents incorporated by reference, if any, in form,


                                       -5-
<PAGE>   6
substance and scope as are customarily made by issuers to underwriters in
underwritten offerings and confirm the same if and when requested, (2) obtain
opinions of counsel to the Company and updates thereof addressed to the
underwriters, if any, with respect to the registration statement, prospectus and
documents incorporated by reference, if any, covering the matters customarily
covered in opinions requested in underwritten offerings and such other matters
as may be reasonably requested by such holders and underwriters, (3) obtain a
"cold comfort" letter and updates thereof from the Company's independent
certified public accountants addressed to the underwriters, if any, which
letters shall be in customary form and cover matters of the type customarily
covered in "cold comfort" letters by accountants in connection with underwritten
offerings, and (4) the Company shall deliver such documents and certificates as
may be reasonably requested by the Stockholders Representative and the managing
underwriters, if any, to evidence compliance with any customary conditions
contained in the underwriting agreement or other agreement entered into by the
Company. The above shall be done at each closing under such underwriting or
similar agreement or as and to the extent required thereunder; and

                           (k) if requested by the Stockholders Representative
use its best efforts to cause all Registerable Securities which are included in
such registration statement to be listed, subject to notice of issuance, by the
date of the first sale of Registerable Securities pursuant to such registration
statement, on each securities exchange, if any, on which the Company's Common
Stock is then listed.

                           The Company may require each seller of Registerable
Securities as to which any registration is being effected to furnish to the
Company such information regarding the distribution of such securities as the
Company may from time to time reasonably request in writing.

                           Each Holder agrees, and each other holder of
Registerable Securities will be required, in its request to register securities
pursuant to this Agreement, to agree, that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 4(c)(2),
4(c)(3), 4(c)(5) or 4(c)(6) hereof, such holder will forthwith discontinue
disposition of Registerable Securities pursuant to the registration statement
covering such Registerable Securities until such holder's receipt of the copies
of the supplemented or amended prospectus contemplated by Section 4(c)(1)
hereof, or until it is advised in writing (the "Advice") by the Company that the
use of the applicable prospectus may be resumed, and until it has received
copies of any additional or supplemental filings which are incorporated by
reference in such prospectus, and, if so directed by the Company, such holder
will deliver to the Company (at the expense of the Company) all copies, other
than permanent file copies then in such holder's possession, of the prospectus
covering such Registerable Securities current at the time of receipt of such
notice.

                  5.       Registration Expenses.

                           All expenses incident to the performance of or
compliance with this Agreement by the Company, including, without limitation,
all registration and filing fees of the Commission, the National Association of
Securities Dealers Inc. and other agencies, fees and


                                       -6-
<PAGE>   7
expenses of compliance with securities or blue sky laws (including reasonable
fees and disbursements of counsel in connection with blue sky qualifications of
the Registerable Securities), rating agency fees, printing expenses, messenger
and delivery expenses, internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the fees and expenses incurred in connection with the
listing, if any, of the securities to be registered on any securities exchange
and fees and disbursements of counsel for the Company and the Company's
independent certified public accountants (including the expenses of any special
audit or "cold comfort" letters required by or incident to such performance),
securities acts liability insurance (if the Company elects to obtain such
insurance), the fees and expenses of any special experts retained by the company
in connection with such registration, and the fees and expenses of any other
person retained by the company (but not including any underwriting discounts or
commissions attributable to the sale of Registerable Securities or other
out-of-pocket expenses of the holders of Registerable Securities (or the agents
who act on their behalf) unless reimbursement is specifically approved by the
Company) will be borne by the Company. All such expenses are herein called
"Registration Expenses". Notwithstanding the foregoing, the Company shall not be
required to pay for any Registration Expenses of any Demand Registration if such
registration request is subsequently withdrawn at the request of the
Stockholders Representative or the holders of a majority of the Registerable
Securities to be registered (in which case all holders which requested the
withdrawal of the registration request shall bear such expenses pro rata).

                  6.       Indemnification; Contribution.

                           (a) Indemnification by the Company. The Company
agrees to indemnify and hold harmless, to the full extent permitted by law, each
holder of Registerable Securities, its officers and directors and each person
who controls such holder (within the meaning of the Securities Act), and any
agent thereof against all losses, claims, damages, liabilities and expenses
incurred by such party pursuant to any actual or threatened suit, action,
proceeding or investigation (including reasonable expenses of investigation)
arising out of or based upon any untrue or alleged untrue statement of a
material fact contained in any registration statement, prospectus or preliminary
prospectus or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein (in
the case of a prospectus, in the light of the circumstances under which they
were made) not misleading, except insofar as the same arise out of or are based
upon, any such untrue statement or omission based upon information with respect
to such holder furnished in writing to the Company by such holder expressly for
use therein.

                           (b) Indemnification by Holder of Registerable
Securities. In connection with any registration statement in which a holder of
Registerable Securities is participating, each such holder will be required to
furnish to the Company in writing such information with respect to such holder
as the Company reasonably requests for use in connection with any such
registration statement or prospectus, and each Purchaser agrees to the extent it
is such a holder, and each other such holder will be required to agree, to
indemnify, to the full extent permitted by law, the Company, the directors and
officers of the Company and each person who controls the Company (within the
meaning of the Securities Act) and any agent thereof, against any losses,
claims, damages, liabilities


                                       -7-
<PAGE>   8
and expenses (including reasonable attorney's fees and expenses of
investigation) incurred by such party pursuant to any actual or threatened suit,
action, proceeding or investigation arising out of or based upon any untrue or
alleged untrue statement of a material fact or any omission or alleged omission
of a material fact necessary to make the statements therein (in the case of a
prospectus, in the light of the circumstances under which they are made) not
misleading, to the extent, but only to the extent, that such untrue statement or
omission is based upon information relating to such holder furnished in writing
to the Company expressly for use therein.

                           (c) Conduct of Indemnification Proceedings. Promptly
after receipt by an indemnified party under this Section 6 of written notice of
the commencement of any action, proceeding, suit or investigation or threat
thereof made in writing for which such indemnified party may claim
indemnification or contribution pursuant to this Agreement, such indemnified
party shall notify in writing the indemnifying party of such commencement or
threat; but the omission so to notify the indemnifying party shall not relieve
it from any liability which it may have to any indemnified party (x) hereunder,
unless the indemnifying party is actually prejudiced thereby or (y) otherwise
than under this Section 6. In case any such action, suit or proceeding shall be
brought against any indemnified party, and it shall notify the indemnifying
party of the commencement thereof, the indemnifying party shall be entitled to
participate therein and the indemnifying party shall assume the defense thereof,
with counsel reasonably satisfactory to the indemnified party and the payment of
all expenses. The indemnified party shall have the right to employ separate
counsel in any such action, suit or proceeding and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party has agreed to pay such
fees and expenses, (ii) the indemnifying party shall have failed to assume the
defense of such action, suit or proceeding or to employ counsel reasonably
satisfactory to the indemnified party therein or to pay all expenses or (iii)
the named parties to any such action or proceeding (including any impleaded
parties) include both the indemnifying party and the indemnifying party and the
indemnifying party shall have been advised by counsel that there may be one or
more legal defenses available to the indemnified party which are different from
or additional to those available to the indemnifying party and which may result
in a conflict between the indemnifying party and such indemnified party (in
which case, if the indemnified party notifies the indemnifying party in writing
that the indemnified party elects to employ separate counsel at the expense of
the indemnifying party, the indemnifying party shall not have the right to
assume the defense of such action or proceeding on behalf of the indemnified
party, it being understood, however, that the indemnifying party shall not, in
connection with any one such action, suit or proceeding or separate but
substantially similar or related actions, suits or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys at
any time for the indemnified party, which firm shall be designated in writing by
the indemnified party).

                           (d) Contribution. If the indemnification provided for
in this Section 6 from the indemnifying party is unavailable to an indemnified
party hereunder in respect of any losses, claims, damages, liabilities or
expenses referred to therein, then the indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such


                                       -8-
<PAGE>   9
indemnified party as a result of such losses, claims, damages, liabilities or
expenses (i) in such proportion as is appropriate to reflect the relative
benefits received by the indemnifying party on the one hand and the indemnified
party on the other or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits received by the indemnifying party on the one hand
and the indemnified party on the other but also the relative fault of the
indemnifying party and indemnified party as well as any other relevant equitable
considerations. The relative fault of such indemnifying party and the
indemnified parties shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party or
indemnified parties, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid
or payable by a party as a result of the losses, claims, damages, liabilities
and expenses referred to above shall be deemed to include, subject to the
limitation set forth in Section 6(e), any legal or other fees or expenses
reasonably incurred by such party in connection with any investigation or
proceeding.

                           The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 6(d) were determined by
pro rata allocation or by any other method of allocation which does not take
into account the equitable considerations referred to in clauses (i) and (ii) of
the immediately preceding paragraph. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

                           (e) Limitation. Anything to the contrary contained in
this Section 6 or in Section 11 hereof notwithstanding, no holder of
Registerable Securities shall be liable for indemnification and contribution
payments aggregating an amount in excess of the maximum amount received by such

created by Bergman during or in connection with Bergman's employment by the
Company ("Intellectual Property"). Bergman agrees that all such Intellectual
Property shall be the sole property of the Company. Bergman further agrees that
Bergman will execute such instruments and perform such acts as may reasonably be
requested by the Company to transfer to and perfect in the Company all legally
protectable rights in such Intellectual Property.
