Dear Stockholder:
 
    You are cordially invited to attend a Special Meeting of Stockholders of
Allegro New Media, Inc. ("Allegro") to be held on         ,         , 1996 at
        , local time, at         . At the Special Meeting, you will be asked to
consider and approve certain proposals relating to the proposed combination of
SPC Acquisition Corporation, a wholly-owned subsidiary of Allegro ("Merger
Sub"), with Software Publishing Corporation ("SPC") (the "Merger") pursuant to
the Agreement and Plan of Reorganization between Allegro, Merger Sub and SPC
(the "Agreement"). The accompanying Prospectus/Joint Proxy Statement presents
the details of the Merger.
 
    After careful consideration, Allegro's Board of Directors has unanimously
approved the Agreement and the transactions contemplated thereby. In making this
determination, the Board of Directors of Allegro has received an opinion from
Frost Capital Partners, Inc. that the Merger is fair to Allegro and the
stockholders of Allegro from a financial point of view. The Board of Directors
of Allegro believes that the proposed Merger and the other proposals described
below are in the best interests of Allegro and unanimously recommends that you
vote FOR (1) the approval of the Agreement and the Merger; (2) an amendment to
the Certificate of Incorporation of Allegro to increase the authorized number of
shares of Common Stock, $.001 par value per share, of Allegro (the "Allegro
Common Stock") from 18,000,000 to 30,000,000, subject to and upon consummation
of the Merger, (3) an amendment to the Certificate of Incorporation of Allegro
to eliminate the Class A Convertible Preferred Stock, the outstanding shares of
which have been converted into shares of Common Stock and (4) an amendment to
the Allegro 1994 Long Term Incentive Plan (the "Allegro Incentive Plan") to
increase by 2,000,000 to 3,000,000 the number of shares of Allegro Common Stock
to be available for grant and reserved for issuance under the Allegro Incentive
Plan (which increase represents approximately 20.3% of the shares of the Allegro
Common Stock estimated to be outstanding or issuable following consummation of
the Merger (based upon the capitalization of Allegro and SPC as of October 1,
1996)), subject to and upon consummation of the Merger.
 
    The Board of Directors of Allegro believes the Merger offers Allegro and its
stockholders a number of important benefits including: (i) the strategic fit
between Allegro and SPC, creating an opportunity for the combined company to
play a significant role in the evolving market for visual communications and
business productivity software products, (ii) the potential for the combined
company to capitalize on the product offerings and the marketing and product
synergies between SPC's and Allegro's product lines, and (iii) the greater
financial, product development, sales and marketing and management resources
that would result from combining the operations of the two companies. In the
Merger, all of the issued and outstanding shares of capital stock of SPC will be
converted into the right to receive an aggregate of approximately 3,372,825
shares of Allegro Common Stock, based on the capitalization of SPC and Allegro
on October 1, 1996. Allegro will also assume options exercisable for up to
approximately 816,926 additional shares of Allegro Common Stock, based on the
number of options to purchase SPC Common Stock, par value $.001 per share ("SPC
Common Stock") outstanding on October 1, 1996. As a result, following the
Merger, based on the shares of SPC Common Stock and Allegro Common Stock
outstanding as of October 1, 1996, the former holders of SPC Common Stock will
hold approximately 43.0% of the Allegro Common Stock, and the holders of Allegro
Common Stock prior to the Merger will hold approximately 57.0% of the Allegro
Common Stock.
 
    All stockholders are invited to attend the Special Meeting in person.
Approval of the Agreement and the Merger by Allegro stockholders is not required
under applicable law; nevertheless, the Board of Directors of Allegro has
determined to seek the affirmative vote of a majority of the total votes cast
regarding the proposal to approve the Agreement and the Merger, with the Allegro
Common Stock and the Allegro Class B Voting Preferred Stock voting together as a
class. The amendment of the Allegro Certificate of Incorporation increasing the
number of authorized shares of Allegro Common Stock requires the affirmative
vote of holders of a majority of the outstanding shares of Allegro Common Stock
and the Allegro Class B Voting Preferred Stock, each voting separately as a
class; the amendment of the Allegro Certificate of Incorporation eliminating the
Class A Convertible Preferred Stock requires the affirmative vote of holders of
a majority of the outstanding shares of Allegro Common Stock and the Allegro
Class B Voting Preferred Stock, voting together as a class; and the amendment to
the Allegro Incentive Plan requires the affirmative vote of a majority of the
total votes cast regarding such proposal, with the Allegro Common Stock and the
Allegro Class B Voting Preferred Stock voting together as a class.
 
    Stockholders are urged to review carefully the information contained in the
accompanying Prospectus/Joint Proxy Statement, including in particular the
information under the captions "Risk Factors," "Allegro New Media, Inc. Special
Meeting--Recommendations of Allegro Board of Directors," "Approval of the Merger
and Related Transactions--Joint Reasons for the Merger" and "--Allegro's Reasons
for the Merger" prior to making any voting decision in connection with their
Allegro Common Stock.
 
    Whether or not you expect to attend the Special Meeting in person, please
complete, sign and promptly return the enclosed proxy card in the enclosed
postage-prepaid envelope to assure representation of your shares. You may revoke
your proxy at any time before it has been voted, and if you attend the Special
Meeting you may vote in person even if you have previously returned your proxy

     Allegro and its subsidiaries design, develop, and market a line of computer
software products principally for the corporate and small office/home office
("SOHO") computer software markets. Allegro currently sells thirty-one (31)
software titles primarily in four product categories: business reference,
business productivity, desktop publishing and tutorials, in addition to its home
reference and family lifestyle products, which Allegro expects to de-emphasize
after completion of the Merger described herein.
 
     Many of Allegro's products are distinguished by licensed brand names such
as Entrepreneur(R) Magazine, as well as Allegro's own Learn to Do(R) brand. In
addition, Allegro's acquisition in July 1996 of its subsidiaries Serif Inc. and
Serif (Europe) Limited (collectively, "Serif") significantly expanded Allegro's
desktop publishing product line to include Serif's existing and new products
PagePlus(TM) Home/Office, DrawPlus(TM) 3.0, Publishing Power Suite and
PagePlus(TM) 4.0 Professional Edition.
 
     Allegro relies primarily on three basic sales channels: retail sales,
direct mail and original equipment manufacturers ("OEMs"). Allegro sells its
products on a direct basis through distributors and to retailers such as
software specialty stores, computer superstores, office superstores, office
supply stores, warehouse clubs, mall-based chains, consumer electronics stores,
mass merchants and bookstores. Retailers purchasing Allegro's products directly
from Allegro or through distributors include Best Buy, CompUSA, Computer City,
Electronics Boutique, Micro Center, Babbages, Software Etc., Staples, Office
Depot, Egghead Discount Software and OfficeMax, as well as major software
retailers in the United Kingdom. Distributors of Allegro's products include
Ingram Micro, Inc., Tech Data, Merisel and Navarre Corp. Allegro maintains a
list of its registered user customers and sends periodic mailings offering to
upgrade versions and new products. Allegro also utilizes telesales operations in
conjunction with its direct mail operations to increase direct sales to existing
and new end-user customers. Allegro sells to a variety of OEMs, which include
Allegro's products in software bundles with their equipment. OEMs to which
Allegro has sold products include IBM, Philips, Twinhead and Xerox.
 
     Allegro was initially incorporated in New Jersey in July 1992 and was
reincorporated in Delaware in December 1993. Allegro maintains its executive
offices at 3 Oak Road, Fairfield, New Jersey 07004, and its telephone number is

Netscape Navigator and an ActiveX version of ASAP WebShow(TM) for Microsoft
Internet Explorer 3.0. SPC also continues to offer word processing and other
business productivity software products.
 
     The majority of SPC's products are sold through corporate reseller and
computer software retail channels. SPC's corporate sales are comprised of both
individual product sales as well as volume sales. Sales through the retail
channel generally are made on a two-step basis, with the initial sales being
made by SPC to distributors and then by the distributors to the actual retail
chains. In addition, SPC distributes its products through OEMs on a bundle or
value-add basis. Corporate reseller and computer software retailers purchasing
SPC's products directly from SPC or through distributors include Stream

THE ALLEGRO COMMON STOCK. SEE "RISK FACTORS."
 
REASONS FOR THE MERGER
 
     The Boards of Directors of SPC and Allegro have authorized the execution
and delivery and performance of the Agreement with the expectation that the
Merger, by combining the experience, management, financial resources, size and
breadth of product offerings of Allegro and SPC, will result in significant
long-term strategic benefits to the Combined Company. See "Risk Factors,"
"Approval of the Merger and Related Transactions--Joint Reasons for the Merger,"
"--Allegro's Reasons for the Merger," and "--SPC's Reasons for the Merger."
 
FAIRNESS OPINIONS
 
     Frost Capital Partners, Inc. ("Frost") has delivered to the Allegro Board
its written opinion, dated September 30, 1996, to the effect that, as of such
date, the Merger was fair to Allegro and its stockholders from a financial point
of view. The full text of the opinion of Frost, which sets forth assumptions
made and matters considered, is attached hereto as Annex B to this
Prospectus/Joint Proxy Statement and is incorporated herein by reference.
HOLDERS OF ALLEGRO COMMON STOCK ARE URGED TO, AND SHOULD, READ SUCH OPINION IN
ITS ENTIRETY. See "Approval of the Merger and Related Transactions--Opinion of
Allegro's Financial Advisor" and Annex B hereto.
 
     Unterberg Harris has delivered to the SPC Board its written opinion, dated
October 11, 1996, to the effect that, as of October 1, 1996, the consideration
to be received by the holders of SPC Common Stock in the Merger was fair from a
financial point of view. The full text of the opinion of Unterberg Harris, which
sets forth assumptions made and matters considered, is attached hereto as Annex
C to this Prospectus/Joint Proxy Statement, and is incorporated herein by
reference. HOLDERS OF SPC COMMON STOCK ARE URGED TO, AND SHOULD, READ SUCH
OPINION IN ITS ENTIRETY. See "Approval of the Merger and Related
Transactions--Opinion of SPC's Financial Advisor" and Annex C attached hereto.
 
INCOME TAX TREATMENT
 
     The Merger is intended to qualify as a reorganization under Section 368(a)
of the Internal Revenue Code of 1986, as amended (the "Code"), in which case no
gain or loss should generally be recognized by the holders of shares of SPC
Common Stock on the exchange of their shares of SPC Common Stock solely for
shares of Allegro Common Stock. SPC has received an opinion from tax counsel
that the Merger will constitute a reorganization under Section 368(a) of the
Code. NONETHELESS, ALL SPC STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS. See "Approval of the Merger and Related Transactions--Certain Federal
Income Tax Considerations" and "Risk Factors--Certain Tax Considerations."
 
REGULATORY MATTERS
 
     Allegro and SPC are aware of no material governmental or regulatory
approvals required for consummation of the Merger, other than compliance with
the federal securities laws and applicable securities and "blue sky" laws of the
various states. See "Approval of the Merger and Related
Transactions--Governmental and Regulatory Approvals."
 
ACCOUNTING TREATMENT
 
     The Merger is intended to be accounted for under the purchase method of
accounting for financial reporting purposes in accordance with generally
accepted accounting principles.

THE MERGER
 
  Terms of the Merger
 
     At the Effective Time (as defined below) of the Merger, Merger Sub will
merge with and into SPC, and Allegro will become the owner of all of the capital
stock of SPC. It is currently intended that the operations of Allegro and SPC
will be combined as soon as practicable following the closing of the Merger. As
a result of the Merger, each outstanding share of SPC Common Stock, other than
shares as to which appraisal rights have been exercised pursuant to the Delaware
General Corporation Law and shares held in the treasury of SPC or owned by
Merger Sub, Allegro or any wholly owned subsidiary of Allegro or SPC, will be
converted into the right to receive 0.26805 shares of Allegro Common Stock, and
each outstanding option or right to purchase SPC Common Stock under the SPC
Stock Option Plans will be assumed by Allegro and will become an option or right
to purchase Allegro Common Stock, with appropriate adjustments to be made to the
number of shares issuable thereunder and the exercise price thereof based on the
Exchange Ratio.
 
     No fractional shares will be issued by virtue of the Merger, but in lieu
thereof each holder of shares of SPC Common Stock (after aggregating all
fractional shares to be received by such holder) will receive from Allegro an
amount of cash (rounded to the nearest whole cent) equal to the product of (i)
such fraction, multiplied by (ii) the average closing price of a share of
Allegro Common Stock for the ten most recent days that the Allegro Common Stock
has traded ending on the trading day immediately prior to the Effective Time, as
reported on Nasdaq/SmallCap. See "Terms of the Merger--Manner and Basis of
Converting Shares."
 
  Effective Time of the Merger
 
     The Merger will become effective upon the filing of a Certificate of Merger
(the "Certificate of Merger") with the Secretary of State of the State of
Delaware or at such later time as may be agreed in writing by Allegro, SPC and
Merger Sub and specified in the Certificate of Merger (the "Effective Time").
Assuming all conditions to the Merger are met or waived prior thereto, it is
anticipated that the Closing Date of the Merger (the "Closing Date") and
Effective Time will be on or about December 31, 1996. See "Terms of the
Merger--Effective Time."
 
  Exchange of SPC Stock Certificates
 
     Promptly after the Effective Time, Allegro, acting through American Stock
Transfer and Trust Company, as its exchange agent (the "Exchange Agent"), will
deliver to each SPC stockholder of record a letter of transmittal with
instructions to be used by such stockholder in surrendering certificates which,
prior to the Merger, represented shares of SPC Common Stock. CERTIFICATES SHOULD
NOT BE SURRENDERED BY THE HOLDERS OF SPC COMMON STOCK UNTIL SUCH HOLDERS RECEIVE
THE LETTER OF TRANSMITTAL FROM THE EXCHANGE AGENT. At the Effective Time, each
then outstanding option or right to purchase SPC Common Stock, whether vested or
unvested, will be assumed by Allegro without any action on the part of the
holder thereof, and the number of shares issuable thereunder and the exercise
price thereof will be appropriately adjusted according to the Exchange Ratio.
OPTION AGREEMENTS NEED NOT BE SURRENDERED. See "Terms of the Merger--Manner and
Basis of Converting Shares."
 
  Form S-8 Registration Statement
 
     No later than ten business days after the Closing Date, Allegro will file a
registration statement on Form S-8 under the Securities Act covering the shares
of Allegro Common Stock issuable upon exercise of options to purchase SPC Common
Stock to be assumed by Allegro at the Effective Time. See "Terms of the
Merger--Manner and Basis of Converting Shares."
 
  Stock Ownership Following the Merger
 
     Based upon the number of shares of SPC Common Stock outstanding and the
number of shares issuable upon exercise of outstanding options to purchase SPC
Common Stock as of October 1, 1996, and assuming
 
                                        8
<PAGE>   17
 
that no holder of SPC Common Stock exercises appraisal rights, an aggregate of
approximately 3,372,825 shares of Allegro Common Stock will be issued to SPC
stockholders in the Merger and Allegro will assume options exercisable for up to
approximately 816,926 additional shares of Allegro Common Stock. Based upon the
number of shares of Allegro Common Stock issued and outstanding as of October 1,
1996, and after giving effect to the issuance of Allegro Common Stock as
described in the previous sentence, the former holders of SPC Common Stock would
hold approximately 43.0% of the Combined Company's total issued and outstanding
shares and would have approximately 40.0% of the voting power of the Company,
and holders of former SPC options would hold options to purchase approximately
9.9% of the Combined Company's total issued and outstanding shares (assuming the
exercise of only such options). The foregoing numbers of shares and percentages
are subject to change in the event that the capitalization of either Allegro or
SPC changes between October 1, 1996 and the Effective Time, and there can be no
assurance as to the actual capitalization of Allegro or SPC at the Effective
Time or of the Combined Company at any time following the Effective Time. See
"Terms of the Merger--Stock Ownership Following the Merger."
 
  Conduct of Combined Company Following the Merger
 
     Pursuant to the Agreement, the full Board of Directors of the Combined
Company following the Merger will consist of up to eleven directors, divided
into three classes. Two directors will be designated by SPC. One designee of SPC
is expected to be Fred Gibbons, the Chairman of the Board of Directors of SPC,
in Class III, and the other SPC designee is expected to be Miriam Frazer, the
Vice President-Finance and Chief Financial Officer of SPC and the Combined
Company, in Class II, both of whom are currently directors of SPC.
 
     Following the Merger, the principal executive officers of the Combined
Company will be as follows: Barry A. Cinnamon, who is currently Chairman of the
Board, President and Chief Executive Office of Allegro, will be Chairman of the
Board, President and Chief Executive Officer of the Combined Company; Mark
Leininger, who is currently Chief Operating Officer, Vice President-Finance,
Chief Financial Officer, and Treasurer of Allegro, will be Vice President, Chief
Operating Officer and Treasurer of the Combined Company; Miriam Frazer, who is
currently Vice President-Finance and Chief Financial Officer of SPC, will be
Vice President-Finance and Chief Financial Officer of the Combined Company;
Daniel Fraisl, who is currently Vice President-Research and Development of SPC,
will be Vice President-Research and Development of the Combined Company; Joseph
Szczepaniak, who is currently Vice President-Sales and Marketing of SPC, will be
Vice President-Sales and Marketing of the Combined Company; James Tsonas, who is
currently Vice-President-Retail Sales of Allegro, will be Vice
President-Corporate Sales of the Combined Company; and Lori Kramer Cinnamon, who
is currently Assistant Vice President-Marketing of Allegro, will be Assistant
Vice President-Marketing of the Combined Company. See "Terms of the
Merger--Conduct of Combined Company Following the Merger."
 
  No Solicitation by SPC
 
     Under the terms of the Agreement, until the earlier of the Effective Time
or termination of the Agreement pursuant to its terms, SPC has agreed that it
and its subsidiaries will not, and will instruct their respective directors,
officers, employees, representatives, investment bankers, agents and affiliates
not to, directly or indirectly, (i) solicit or knowingly encourage submission
of, any proposals or offers by any person, entity or group (other than Allegro
and its affiliates, agents and representatives), or (ii) participate in any
discussions or negotiations with, or disclose any non-public information
concerning itself or any of its subsidiaries to, or afford any access to the
properties, books or records of itself or any of its subsidiaries to, or
otherwise assist or facilitate, or enter into any agreement or understanding
with, any person, entity or group (other than Allegro and its affiliates, agents
and representatives), in connection with any Acquisition Proposal with respect
to SPC. For the purposes of the Agreement, an "Acquisition Proposal" with
respect to an entity means any proposal or offer relating to (i) any merger,
consolidation, sale of substantial assets or similar transactions involving the
entity or any subsidiaries of the entity (other than sales of assets or
inventory in the ordinary course of business or permitted under the terms of the
Agreement), (ii) sale of 5% or more of the outstanding shares of capital stock
of the entity (including without limitation by way of a tender offer or an
exchange offer), (iii) the acquisition by any person of beneficial ownership or
a right to acquire beneficial
 
                                        9
<PAGE>   18
 
ownership of, or the formation of any "group" (as defined under Section 13(d) of
the Exchange Act and the rules and regulations thereunder) which beneficially
owns, or has the right to acquire beneficial ownership of, 5% or more of the
then-outstanding shares of capital stock of the entity (except for acquisitions
for passive investment purposes only in circumstances where the person or group
qualifies for and files a Schedule 13G with respect thereto); or (iv) any public
announcement of a proposal, plan or intention to do any of the foregoing or any
agreement to engage in any of the foregoing. SPC has agreed to cease any and all
existing activities, discussions or negotiations with any parties conducted
prior to the signing of the Agreement with respect to any of the foregoing. SPC
has agreed to (i) notify Allegro as promptly as practicable if any inquiry or
proposal is made or any information or access is requested in writing in
connection with an Acquisition Proposal or potential Acquisition Proposal and
(ii) as promptly as practicable notify Allegro of the significant terms and
conditions of any such Acquisition Proposal. In addition, subject to other
provisions discussed below, from and after the date of the Agreement until the
earlier of the Effective Time and the termination of the Agreement pursuant to
its terms, SPC and its subsidiaries have agreed not to, and have agreed to
instruct their respective directors, officers, employees, representatives,
investment bankers, agents and affiliates not to, directly or indirectly, make
or authorize any public statement, recommendation or solicitation in support of
any Acquisition Proposal made by any person, entity or group (other than
Allegro); provided, however, that nothing in the Agreement will prohibit the
Board of Directors of SPC from taking and disclosing to its stockholders a
position with respect to a tender offer pursuant to Rules 14d-9 and 14e-2
promulgated under the Exchange Act.
 
     Notwithstanding the foregoing, SPC may, to the extent its Board of
Directors determines, in good faith, after consultation with outside legal
counsel, that the SPC Board's fiduciary duties under applicable law require it
to do so, participate in discussions or negotiations with, and, subject to the
requirements discussed below, furnish information to any person, entity or group
after such person, entity or group has delivered to SPC, in writing, an
unsolicited bona fide Acquisition Proposal which its Board of Directors in its
good faith reasonable judgment determines, after consultation with its
independent financial advisors, would result in a transaction more favorable to
the stockholders of SPC from a financial point of view than the Merger and for
which financing, to the extent required, is then committed or which, in the good
faith reasonable judgment of the Board of Directors of SPC (based upon the
advice of independent financial advisors), is reasonably capable of being
financed by such person, entity or group, and which is likely to be consummated
(a "Superior Proposal"). In the event SPC receives a Superior Proposal, nothing
contained in the Agreement will prevent the Board of Directors of SPC from
approving such Superior Proposal or recommending such Superior Proposal to its
stockholders, if the SPC Board determines that such action is required by its
fiduciary duties under applicable law; provided, however, that SPC has agreed
not to accept or recommend to its stockholders, or enter into any agreement
concerning, a Superior Proposal for a period of not less than 48 hours after the
receipt by Allegro of a copy of such Superior Proposal (or a description of the
significant terms and conditions thereof, if not in writing). See "Terms of the
Merger--No Solicitation by SPC and "Terms of the Merger--Break Up Fees;
Expenses" and "Termination of the Agreement."

  Termination; Fees
 
     The Agreement may be terminated under certain circumstances, including,
without limitation, (i) by mutual written consent of Allegro and SPC authorized
by their respective Boards of Directors; (ii) by either Allegro or SPC (A) if
the other party commits certain breaches of representations, warranties or
covenants contained in the Agreement; (B) if consummation of the Merger is
restricted by an order or other action of a court of competent jurisdiction or a
governmental, regulatory or administrative agency or commission; (C) if the
Merger is not consummated on or before February 15, 1997 (except that the
Agreement cannot be terminated pursuant to this provision by a party whose
action or failure to act has been a principal cause of the failure of the Merger
to occur on or before such date and such action or failure to act constitutes a
breach of the Agreement); or (D) if a material adverse effect with respect to
the other party has occurred since the date of the Agreement.
 
     SPC has agreed that if it accepts a Superior Proposal, if the Board of
Directors of SPC recommends a Superior Proposal to the stockholders of SPC, if
the stockholders of SPC fail to approve the Merger following a publicly
disclosed (and not withdrawn) Acquisition Proposal with regard to SPC, or if the
stockholders of SPC fail to approve the Merger following the withholding,
withdrawal or modification by the Board of Directors of SPC, in a manner adverse
to Allegro, of its recommendation in favor of the Merger, then SPC will
immediately pay to Allegro the sum of $1 million. Each of Allegro and SPC have
agreed that, in the case that either company's stockholders fail to approve the
Merger under circumstances not described in the preceding sentences, or if such
company fails to perform or observe any of its covenants contained in the
Agreement, then such company will immediately pay to the other the sum of
$750,000. See "Terms of the Merger--Break Up Fees; Expenses," and "--Termination
of the Agreement."
 
  Conditions to the Merger
 
     Consummation of the Merger is subject to the satisfaction of various
conditions, including approvals by the requisite vote of the stockholders of
Allegro and SPC. Consummation of the Merger is also subject to the satisfaction
of the following conditions: the Registration Statement filed with the SEC
relating to the issuance of shares of Allegro Common Stock in connection with
the Merger shall be effective; such shares shall be authorized for listing on
Nasdaq/SmallCap; and no injunction, court order, or other legal restraint
preventing consummation of the Merger shall be in effect. In addition, the
obligations of SPC to consummate the Merger are subject to the following
conditions, unless waived by SPC: the representations and warranties of Allegro
and Merger Sub contained in the Agreement shall be accurate, except where any
breach or breaches did not have or would not reasonably be expected to have a
material adverse effect on Allegro; Allegro and Merger Sub shall have performed
in all material respects the covenants required by the Agreement; no material
adverse effect with respect to Allegro shall have occurred; and SPC shall have
received a legal opinion from counsel representing Allegro. Similarly, the
obligations of Allegro to consummate the Merger are subject to the following
conditions, unless waived by Allegro: the representations and warranties of SPC
contained in the Agreement shall be accurate, except where any breach or
breaches did not have or would not reasonably be expected to have a material
adverse effect on SPC; SPC shall have performed in all material respects the
covenants required by the Agreement; no material adverse effect with respect to
SPC shall have occurred; and Allegro shall have received a legal opinion from
counsel representing SPC. See "Terms of the Merger--Conditions to the Merger."
 
  Interests of Certain Persons in the Merger
 
     In considering the recommendation of the SPC Board with respect to the

  Appraisal Rights
 
     Holders of Allegro Common Stock are not entitled to appraisal rights under
the Delaware General Corporation Law in connection with the Merger. Holders of
SPC Common Stock will be entitled to appraisal rights under the Delaware General
Corporation Law in connection with the Merger. A holder of SPC Common Stock who
desires to pursue appraisal rights must (i) file a written objection to the
Agreement with SPC before the taking of the stockholders' vote on the Agreement,
(ii) refrain from voting in favor of the Agreement, and (iii) make written
demand from the surviving corporation for payment for the stockholder's shares,
all in accordance with the Delaware General Corporation Law. Such appraisal
rights are conditioned upon not voting for the Agreement. See "Terms of the
Merger--Appraisal Rights."
 
  Anti-takeover Provisions of Delaware Law and the Combined Company's Charter
Documents
 
     Delaware Law and the Certificate of Incorporation of the Combined Company
contain a number of provisions which may have the effect of delaying,
discouraging or defeating an attempt by a third party to take control of the
Combined Company without the approval of the Board of Directors of the Combined
Company. The Combined Company will be subject to the provisions of Section 203
of the Delaware General Corporation Law, which restricts the corporation from
entering into certain "business combinations" with an "interested person" for a
period of three years. An interested person is generally defined to mean a
person or entity that has acquired in excess of 15% of the Combined Company's
voting stock. In addition, the Combined Company's Board will have authority to
issue up to 1,939,480 shares of preferred stock and to fix the rights,
preferences, privileges and restrictions, including voting rights, of such
shares without any further vote or action by the stockholders. The issuance of
such preferred stock could have a dilutive effect upon the stockholders of the
Combined Company, and could discourage an unsolicited attempt to take over the
Combined Company. The Combined Company's Board of Directors will be classified
into three classes, which would permit a person who wishes to propose an
alternative slate of nominees to such Board of Directors to propose nominees for
only one-third of the Board of Directors at a time. Allegro also has 60,250
shares of Class B Voting Preferred Stock issued and outstanding and held by
Barry A. Cinnamon, each share of which is entitled to cast 10 votes on each
matter to be acted upon by holders of Allegro Common Stock. The Combined Company
will have a requirement in its Certificate of Incorporation that 66 2/3% of the
stockholders of the Combined Company entitled to vote thereon approve certain
transactions, including mergers and sales or transfers of all or substantially
all of the assets of the Combined Company to "interested persons" as defined in
Section 203 of the Delaware General Corporation Law, and a provision in its
By-Laws which requires the consent of 66 2/3% of the stockholders of the
Combined Company to request a special meeting of stockholders (other than a
special meeting called by the Board of Directors or President of the Combined
Company). These provisions will continue in effect after the Merger. See
"Comparison of Capital Stock."
 
LOAN FACILITY
 
     Pursuant to the Agreement, SPC has agreed to loan Allegro up to $1,000,000
(the "Loan Facility"). Funds may be advanced to Allegro in amounts not exceeding
$333,333 in any 30-day period. Funds advanced may be used only for working
capital purposes. In the event the Merger is not consummated for any reason, all
amounts advanced to Allegro under the Loan Facility will be automatically
converted into Allegro Common Stock at a conversion price of 90% of the average
of the last reported sales prices of the Allegro Common Stock for the ten
trading days ending on the day immediately prior to the date of termination
leading to conversion of the amounts advanced under the Loan Facility (the "Loan
Conversion Price"); however, in the event the Agreement is terminated under
circumstances in which SPC is required to pay Allegro a termination fee, then
only one-half the amounts advanced under Loan Facility will be converted into
Allegro Common Stock at the Loan Conversion Price, and the remaining one-half
shall be payable to SPC in cash at the time and in the same manner as the
payment of such termination fee. As of October 28, 1996, no advances had been
made under the Loan Facility.

                                  RISK FACTORS
 
     THE FOLLOWING FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING THE
PROPOSALS TO BE VOTED ON AT THE ALLEGRO MEETING AND THE SPC MEETING AND THE
ACQUISITION OF THE SECURITIES OFFERED HEREBY. THIS SECTION CONTAINS
FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. ACTUAL RESULTS
COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD-LOOKING
STATEMENTS AS A RESULT OF CERTAIN FACTORS, INCLUDING THOSE SET FORTH IN THE
FOLLOWING RISK FACTORS AND ELSEWHERE HEREIN.
 
UNCERTAINTIES RELATING TO INTEGRATION OF OPERATIONS AND THE SERIF ACQUISITION
 
     Allegro and SPC have entered into the Agreement with the expectation that
the proposed Merger will result in long-term strategic benefits. These
anticipated benefits will depend in part on whether the companies' operations
can be integrated in an efficient and effective manner. There can be no
assurance that this will occur. The combination of the companies will require,
among other things, integration of the companies' respective product offerings
and coordination of the companies' sales, marketing and research and development
efforts.
 
     The successful combination of companies and product lines in the software
applications industry may be more difficult and require a greater period of time
to accomplish than in other industries. The success of the Combined Company's
software application business will require communication and cooperation in
product development and marketing among the senior executives and key technical
personnel of Allegro and SPC. Given the inherent difficulties involved in
completing a major business combination there can be no assurance than such
cooperation will occur or that the integration of the respective businesses will
be successful and will not result in disruptions in the Combined Company's
business. In addition, there can be no assurance that the Combined Company will
retain its key technical and management personnel, or that the Combined Company
will realize any of the anticipated benefits of the Merger. The success of the
integration process will be significantly influenced by the ability of the
Combined Company to attract and retain key management, sales, marketing and
research and development personnel, while concurrently minimizing the Combined
Company's costs and expenses. There is no assurance that the foregoing will be
accomplished smoothly or successfully. The integration of operations following
the Merger will require the dedication of management resources, which may
distract attention from the day-to-day operations of the Combined Company. The
inability of management to successfully integrate the operations of the
companies could have a material adverse effect upon the business, operating
results and financial condition of the Combined Company.
 
     Additionally, although SPC and Allegro believe that the Combined Company
will benefit from the combination of the distribution channels of each, there
can be no assurance that the Combined Company will be able to take full
advantage of such combination. Allegro and SPC also use a number of distribution
channels in the various geographic markets in which their respective products
are sold and there can be no assurance that channel conflicts will not develop
following the Merger as the Combined Company attempts to integrate these
channels.
 
     Allegro has recently completed the acquisition of Serif, and the Combined
Company may acquire other companies, products or technologies in the future.
There can be no assurance that these acquisitions and the Merger between Allegro
and SPC can be effectively integrated, that such acquisitions will not result in
costs or liabilities that could materially and adversely affect the Combined
Company's business, operating results and financial condition, or that the
Combined Company will obtain the anticipated or desired benefits of such
transactions.
 
NO EFFECT ON EXCHANGE RATIO OF PRICE OF ALLEGRO COMMON STOCK
 
     Under the terms of the Agreement, each share of SPC Common Stock issued and
outstanding at the Effective Time will be converted into the right to receive
0.26805 shares of Allegro Common Stock. The Agreement does not contain any
provisions for adjustment of the Exchange Ratio based on fluctuations in the
price of Allegro Common Stock or the SPC Common Stock. Accordingly, the value of
the consideration to be received by stockholders of SPC upon the Merger will
depend on the market price of the Allegro Common Stock at the Effective Time.
The Exchange Ratio is based on an arms-length negotiation between Allegro and
 
                                       17
<PAGE>   26
 
SPC. There can be no assurance that the market price of the Allegro Common Stock
after the Effective Time will not be lower than either the price of the Allegro
Common Stock or the price of SPC Common Stock at or prior to the Effective Time.
 
TRANSACTION EXPENSES; COST OF INTEGRATION; EXPECTED WRITE-OFF
 
     Allegro and SPC estimate they will incur direct transaction costs of
approximately $2 million associated with the Merger. In addition, the Combined
Company expects to incur an additional significant charge to operations, which
is currently estimated to be approximately $14,200,000, in respect of in-process
research and development in the quarter in which the Merger is expected to be
consummated, and expenses which currently are not expected to exceed $5 million,
to reflect costs associated with integrating the two companies. There can be no
assurance that the Combined Company will not incur additional material charges
in subsequent quarters to reflect additional costs associated with the Merger.
 
NO ASSURANCE OF PROFITABILITY; LOSSES TO DATE; SUBSTANTIAL REDUCTIONS IN SPC NET
REVENUES
 
     Allegro has been unprofitable since inception in July 1992 and expects to
incur operating losses in the course of building the business of the Combined
Company for at least the next several months. The Combined Company's operating
losses may increase as it develops, produces and distributes additional
products, de-emphasizes certain products and integrates the Serif and SPC
operations, and such losses may fluctuate from quarter to quarter.
 
     SPC has experienced substantial reductions in its net revenues in recent
years. For the years ended September 30, 1992, 1993, 1994, 1995 and 1996, SPC's
revenues were $156.4 million, $104.4 million, $61.5 million, $31.4 million, and
$13.0 million, respectively. SPC believes that these substantial reductions in
revenue were caused in large part by the adoption by users of the Windows and
Windows 95 operating systems, competitive software packages, lower selling
prices, the bundling of software into suites of application programs and other
competitive factors. See "Risk Factors--Competition" and "SPC Management's
Discussion and Analysis of Financial Condition and Results of Operations." There
is no assurance that the Combined Company will be able to overcome these factors
in the future.
 
     No assurance can be given that the combination of Allegro and SPC, each of
which has experienced losses in recent years, will result in a profitable
Combined Company. See "Allegro Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "SPC Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
CHANGE IN SPC PRODUCT STRATEGY
 
     In fiscal year 1996, 70% of SPC's net revenue was derived from the Harvard
Graphics line of products; however, net revenues for the line declined
substantially from the prior year. SPC believes that the market for the Harvard
Graphics product line has matured, as evidenced by declining net revenues from
that product line, and that greater opportunities exist for products based on
Intelligent Formatting technology in both current and emerging markets.
Accordingly, in August 1996, following the announcement of its third fiscal
quarter results, SPC changed its product strategy away from the Harvard Graphics
products toward emphasizing products embodying SPC's recently acquired
Intelligent Formatting technology. The first Intelligent Formatting product was
introduced by SPC in the fiscal quarter ended September 30, 1995. There can be
no assurance that this transition can be accomplished in a timely or efficient
manner, or that products based on Intelligent Formatting technology will achieve
market acceptance or be commercially successful. See "SPC--SPC Business."
 
COMPETITION
 
     The market for visual communications and business productivity software is
highly competitive and subject to rapid technological change. Many of Allegro's
and SPC's current and potential competitors possess significantly greater
financial, technical and marketing resources, greater name recognition and a
larger installed customer base than the Combined Company will have. In addition,
many of these competitors may be able to respond more quickly to new or emerging
technologies and changes in customer requirements, and to devote greater
resources to the development, promotion and sale of their products than the
Combined
 
                                       18
<PAGE>   27
 
Company. Furthermore, because there are relatively low barriers to entry in the
software industry, Allegro and SPC expect additional competition from other
established and emerging companies, which may choose to enter the market by
developing products that compete with those offered by the Combined Company or
by acquiring companies, businesses, products or product lines that compete with
the Combined Company. It is also possible that alliances among competitors may
emerge and rapidly acquire significant market share. Allegro and SPC also
believe that competition will increase as a result of software industry
consolidation. There can be no assurance that the Combined Company's current or
potential competitors will not develop or acquire products comparable or
superior to those developed by the Combined Company, combine or merge to form
significant competitors, or adapt more quickly than the Combined Company to new
technologies, evolving industry trends and changing customer requirements.
Increased competition could result in price reductions, reduced margins or loss
of market share, any of which could materially and adversely affect the Combined
Company's business, operating results and financial condition. There can be no
assurance that the Combined Company will be able to compete successfully against
current and future competitors or that competitive pressures faced by the
Combined Company will not have a material adverse effect on its business,
operating results and financial condition. If the Combined Company is unable to
compete successfully against current and future competitors, the Combined
Company's business, operating results and financial condition will be materially
and adversely affected.
 
     Some of the competitors of the Combined Company sell "bundles" or "suites"
of products which include products that directly compete with Combined Company's
products and which are bundled with other office software programs by the same
or multiple competitors. These suite products are sold at an all-inclusive
price. Additionally, application software is increasingly bundled and preloaded
into new computers. The price for a stand-alone or pre-loaded bundle or suite of
software is typically significantly less than separately purchased applications,
and many end users are likely to prefer the bundle or suite over a more
expensive combination of other individually purchased applications, even if the
latter applications offer superior performance or features. These factors have
resulted and will continue to cause significant downward pressures on average
selling prices for the Combined Company's products. There is no assurance that
the Combined Company will be able to adopt strategies to compete successfully in
this environment.
 
     The primary competitor of Allegro and SPC is, and the primary competitor of
the Combined Company is expected to be, Microsoft Corporation. In addition,
based on product lines and price points, Allegro regards Symantec, Corel,
SoftKey International, Expert Software, Individual Software, Inc. and IMSI as
close competitors.
 
     The dominant position of Microsoft in the personal computer operating
system and application program market place provides it with competitive
advantages, including the ability to determine the direction of future operating
systems and to leverage its strength in one or more product areas to achieve a
dominant position in new markets. This position may enable Microsoft to increase
its market position even with respect to products having performance, price and
features superior to those offered by Microsoft. Microsoft's ability to offer
corporate and SOHO productivity software, to bundle software, to provide
incentives to customers to purchase certain products in order to obtain
favorable sales terms or necessary compatibility or information with respect to
other products, and to pre-load such bundled software on new computers may
significantly inhibit the Combined Company's ability to maintain or expand its
business. In addition, as Microsoft or other companies create new operating
systems and applications, there can be no assurance that the Combined Company
will be able to ensure that its products will be compatible therewith. The
introduction of upgrades to operating systems or the introduction of new
operating systems and standardized software by Microsoft and others, matters
over which the Combined Company has no control, may adversely affect the
Combined Company's ability to upgrade its own products, and may cause reduction
in sales of the Combined Company's products.
 
     In addition, Allegro and SPC anticipate that the Combined Company will face
additional competition from other independent software companies, including
those not currently in the personal computer applications software market but
which may decide to enter this market in the future. Many of these companies may
have financial and other resources substantially superior to those of the
Combined Company.
 
     Allegro and SPC believe that the principal competitive factors in the
corporate and SOHO software market include pricing (which includes individual
product pricing, standard and competitive upgrade pricing,
 
                                       19
<PAGE>   28
 
licensing and volume discounting), product functionality and ease of use,
inclusion in suites of office products, brand name recognition, availability and
quality of training and support, quality of documentation, operating platform
availability, compatibility and integration. The Combined Company's ability to
compete will be contingent on its continued enhancement of its existing
products, its ability to correctly identify and enter new markets, market and
sell its current products and develop new products adapted to changes in
computer hardware and operating systems and new means of distributing software.
Allegro and SPC believe that competition will continue to intensify in the
future and that new product introductions, further price reductions, strategic
alliances and other actions by competitors could materially and adversely affect
the Combined Company's competitive position. See "Allegro--Allegro Business" and
"SPC--SPC Business."
 
NEED FOR ADDITIONAL FUNDS
 
     Allegro and SPC anticipate that the Combined Company will require
additional funds to finance operations and to sustain and expand its combined
product development activities. Furthermore, these capital needs may increase if
additional well-financed competitors emerge in the corporate and SOHO software
market or if there is a rapid shift in the type of platforms that are developed
and ultimately receive market acceptance. If the Combined Company does not
attain its revenue and cash collection goals or if its cash resources are not
sufficient, it may be necessary to obtain additional sources of financing which
may or may not be available or available upon favorable terms.
 
     To the extent that the Combined Company requires additional funds, such
funds on terms favorable to the Combined Company, whether through equity
financing, debt financing or other sources, may not be available when needed and
may result in significant dilution to existing stockholders. The Combined
Company has no bank or other credit facility or other readily available access
to debt financing. Further, the Combined Company's ability to raise additional
capital when required may be adversely affected by its agreements with M.S.
Farrell & Co., Inc. ("MS Farrell"), the underwriter of Allegro's initial public
offering (the "IPO") in December 1995, pursuant to which MS Farrell has the
right of first refusal with respect to public or private offerings of securities
of Allegro, and following the Merger the Combined Company, for a five-year
period commencing upon the consummation of the IPO and is Allegro's, and will be
the Combined Company's, exclusive investment banking firm. In addition, Allegro
has agreed that until the earlier of December 6, 2000 or the exercise of 75% of
the Underwriter's Purchase Options granted in connection with the IPO, Allegro
(which after the Merger is the Combined Company) will not issue any shares of
its Allegro Common Stock or securities convertible into shares of Allegro Common
Stock at a price per share less than 80% of the fair market value of the Allegro
Common Stock unless such issuance is approved by at least three-quarters of the
members of the Combined Company's Board of Directors present at a meeting,
including the designee of MS Farrell serving on the Combined Company's Board of
Directors. If the Combined Company is unable to secure additional funding when
required, the Combined Company would most likely reduce new product development,
marketing activities and/or other aspects of its operations. Ultimately, the
inability to obtain sufficient funds from operations or external sources could
have a material adverse effect on the long-term viability of the Combined
Company. See "Allegro Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
POSSIBLE EFFECTS OF MERGER ON CUSTOMERS
 
     There can be no assurance that the present and potential customers of SPC
and Allegro will continue their current buying or payment patterns without
regard to the proposed Merger. Any significant delay or reduction in orders
could have an adverse effect on the business and results of operations of the
Combined Company. In addition, uncertainties regarding product overlap of the
companies' respective visual communications and desktop publishing products
(such as Allegro's PagePlus and SPC's ActiveOffice (which is expected to ship in
early 1997)) may cause customers to delay or change purchasing decisions
regarding these products.
 
RISKS ASSOCIATED WITH EXPANSION INTO NEW MARKETS; EMERGING MARKET FOR VISUAL
COMMUNICATIONS AND BUSINESS PRODUCTIVITY SOFTWARE
 
     The Combined Company can be expected to introduce new products in the
visual communications and business productivity software markets. Broad market
acceptance of the Combined Company's new products is critical to the Combined
Company's future success. Each of Allegro and SPC believes that factors
affecting
 
                                       20
<PAGE>   29
 
the ability of the Combined Company's products to achieve broad market
acceptance include: product performance, price, ease of adoption, displacement
of existing approaches and adaptation to rapid technological change and
competitive product offerings. There can be no assurance that the Combined
Company will be able to respond promptly and effectively to the challenges of
technological change and its competitors' innovations, or that the Combined
Company will be able to achieve the necessary market acceptance, or compete
effectively, in the visual communications and business productivity software
markets. See "Allegro--Allegro Business."
 
     Although demand for Allegro's products has grown in recent years, the
market for visual communications and other business productivity software is
still emerging and any future growth depends upon continued market acceptance of
such tools. Historically, each of Allegro and SPC has been required to establish
new product markets by educating prospective customers as to the advantages of
its products. Each of Allegro and SPC expects that new product markets may need
to be established for its future products, which will require significant sales
and marketing resources. There can be no assurance that the market for each of
Allegro's and SPC's existing products will grow or that the Combined Company
will be successful in establishing markets for its new products. There is no
assurance that growth of sales of new products will offset the steep decline in
sales of Harvard Graphics products. If the markets for visual communications and
business productivity software fail to grow or grow differently than Allegro and
SPC currently anticipate, or if the Combined Company is unable to establish
markets for its new products, the Combined Company's business, operating results
and financial condition would be materially adversely affected.
 
FLUCTUATIONS IN QUARTERLY RESULTS; FUTURE OPERATING RESULTS UNCERTAIN
 
     Each of Allegro's and SPC's quarterly operating results have in the past,
and the Combined Company's results may in the future, fluctuate significantly
depending on factors such as demand for its products, the size and timing of
orders, the number, timing and significance of new product announcements by it
and its competitors, its ability to develop, introduce and market new and
enhanced versions of its products on a timely basis, the level of product and
price competition, changes in operating expenses, changes in average selling
prices and product mix, changes in its sales incentive strategy, sales personnel
changes, the mix of direct and indirect sales, product returns, changes in
technology and general economic factors, among others. Allegro and SPC have
routinely received, and the Combined Company may routinely receive, a
substantial portion of its orders in the last month of a quarter, with these
orders frequently concentrated in the last weeks or days of a quarter. As a
result, because product revenues in any quarter may be substantially dependent
on orders booked and shipped in that quarter, revenues for any future quarter
may not be predictable with any significant degree of accuracy. Product revenues
are also difficult to forecast because the market for visual communications and
business productivity software is rapidly evolving. The Combined Company's
expense levels, however, will be based in significant part on expectations of
future revenues and therefore will be relatively fixed in the short run. If
revenue levels are below expectations, operating results are likely to be
adversely affected. Net income may be disproportionately affected by an
unanticipated decline in revenue for a particular quarter because a relatively
small amount of the Combined Company's expenses will vary with its revenues in
the short run. As a result, Allegro and SPC believe that period-to-period
comparisons of Allegro's, SPC's or the Combined Company's results of operations
are not and will not necessarily be meaningful and should not be relied upon as
any indication of future performance. Due to all of the foregoing factors, it is
likely that in some future quarter the Combined Company's operating results will
be below the expectations of public market analysts and investors. In such
event, the price of the Allegro Common Stock would likely be materially
adversely affected. Although Allegro has experienced growth in revenues in
recent years, SPC has experienced significant revenue declines in recent years,
and there can be no assurance that, in the future, the Combined Company will
sustain revenue growth or become profitable on a quarterly or annual basis. See
"Allegro Management's Discussion and Analysis of Financial Condition and Results
of Operations" and "SPC Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
RAPID TECHNOLOGICAL CHANGE; NEW PRODUCT DELAYS; RISK OF PRODUCT DEFECTS
 
     The software market is characterized by ongoing technological developments,
evolving industry standards, frequent new product introductions and rapid
changes in customer requirements and preferences. The
 
                                       21
<PAGE>   30
 
introduction of products embodying new technologies and the emergence of new
industry standards and practices can render existing products obsolete and
unmarketable. In 1993 and 1994, for example, there was a significant shift in
consumer demand from DOS-based software to Windows-based software. More
recently, consumer demand has been shifting from disk-based software to software
on CD-ROMs. Moreover, although the installed base of CD-ROM drives in personal
computers has risen significantly in recent years, the growth of sales of CD-ROM
titles has not met industry forecasts. CD-ROMs are currently used to distribute
applications software, reference materials, games, and educational material
among other content. Software is also distributed on diskette, and increasingly,
through on-line services such as CompuServe and America OnLine, and through the
Internet. It is by no means clear that distribution by CD-ROM or the Internet
will become or remain a major means for the distribution of software. To the
extent that the on-line services and the Internet become the preferred method of
customers to receive software, the Combined Company will need to restructure its
operations and distribution channels. There is no assurance that it will be able
to do so. There can be no assurance that the current demand for the Combined
Company's primarily Windows-based products will continue or that the mix of the
Combined Company's future product offerings will keep pace with technological
changes or satisfy evolving consumer preferences. The Combined Company's future
business, operating results and financial condition will depend on its ability
to enhance its existing products, develop new products that address the
increasingly sophisticated needs of its customers, develop products for
additional platforms such as the Internet and respond to technological advances
and emerging industry standards and practices. There can be no assurance that
the Combined Company will be successful in developing, introducing and marketing
product enhancements, new products, or versions of existing products on a timely
basis, if at all, or that it will not experience difficulties that could delay
or prevent the successful development, introduction or marketing of these
products, or that its new products and product enhancements will adequately meet
the requirements of the marketplace and achieve market acceptance. Delays in the
commencement of commercial shipments of new products or enhancements may result
in customer dissatisfaction and delay or loss of product revenues, and the
announcement of new products may cause customers to defer purchases of existing
products. If the Combined Company is unable, for technological or other reasons,
to develop and introduce new products or enhancements of existing products in a
timely manner in response to changing market conditions or customer
requirements, or if new versions of existing products do not achieve market
acceptance, the Combined Company's business, operating results and financial
condition will be materially adversely affected. Software products as complex as
those offered by Allegro and SPC may contain undetected errors or failures when
first introduced or as new versions are released. Although neither Allegro nor
SPC has experienced material adverse effects resulting from any software errors
in any recent years, there can be no assurance that, despite testing internally
or by current or potential customers, errors will not be found in new products
after commencement of commercial shipments, resulting in loss of or delay in
market acceptance, which could have a material adverse effect upon the Combined
Company's business, operating results and financial condition.
 
MANAGEMENT OF GROWTH; DEPENDENCE ON KEY PERSONNEL
 
     Although SPC has substantially reduced its number of employees and
operations each year since 1992, Allegro has recently experienced a period of
growth that has placed strain upon its management systems and resources. In the
future, the Combined Company will be required to continue to improve its
financial and management controls, reporting systems and procedures on a timely
basis and train and manage its employee work force. There can be no assurance
that the Combined Company will be able to effectively manage such growth. Its
failure to do so would have a material adverse effect upon its business,
operating results and financial condition. Competition for qualified sales,
technical and other qualified personnel is intense, and there can be no
assurance that the Combined Company will be able to attract, assimilate or
retain additional highly qualified employees in the future. If the Combined
Company is unable to hire and retain such personnel, particularly those in key
positions, its business, operating results and financial condition would be
materially adversely affected. The Combined Company's future success also
depends in significant part upon the continued service of its key technical,
sales and senior management personnel. The loss of the services of one or more
of these key employees could have a material adverse effect on its business,
operating results and financial condition. Additions of new and departures of
existing personnel, particularly in key positions, can be
 
                                       22
<PAGE>   31
 
disruptive, which could have a material adverse effect upon the Combined
Company's business, operating results and financial condition.
 
RISKS RELATING TO CONTENT LICENSES
 
     Allegro licenses content for its products from several publishing
companies, individual authors and celebrities. These license agreements
typically have terms initially extending for two to four years, and in certain
instances, Allegro has additional renewal options with respect thereto. However,
no assurance can be given that, if it so desires, Allegro will be able to renew
these license agreements beyond their initial terms, even where Allegro has
developed successful products utilizing the content covered by these licenses.
In addition, only Allegro's license agreement relating to its Cooking with Dom
DeLuise product grants to Allegro exclusive electronic publishing rights with
respect to such content. Each of Allegro's other material license agreements
grant to Allegro only CD-ROM publishing rights, on an exclusive or non-exclusive
basis. See "Allegro--Allegro Business." Accordingly, if media other than CD-ROM
(such as on-line services or the Internet) become popular for computer software
products such as those produced by the Combined Company, the Combined Company
will be required to license the content used in connection with its products for
such media, or else it will not be permitted to sell such products on such
platforms. No assurance can be given that the Combined Company will be able to
successfully obtain the right to publish its existing or new products in formats
or on media other than CD-ROM or that its existing licenses relating to the
CD-ROM media will be able to be renewed upon their expiration or extended to
other platforms on terms favorable or acceptable to the Combined Company.
 
UNCERTAINTY OF MARKET ACCEPTANCE; SHORT PRODUCT LIFE CYCLES
 
     Customer preferences for software products are difficult to predict, and
few software products achieve sustained broad market acceptance. The Combined
Company's success is dependent on the market acceptance of its existing products
and the continued development and introduction of new products which achieve
market acceptance. In this connection, Allegro and SPC have attempted to
concentrate their new product development efforts on products which they believe
may have a more extended product life cycle, which Allegro and SPC expect to be
able to continue to sell for longer periods with periodic updates. Allegro and
SPC have also implemented targeted sales and marketing programs which attempt to
maximize sales of older products in appropriate sales channels primarily by
selling such products at reduced prices. There can be no assurance that the
Combined Company's existing or new products will achieve market acceptance, or
sustain any such acceptance for any significant period. Failure of the Combined
Company's new and existing products to achieve and sustain market acceptance
would have a material adverse effect on the Combined Company's business,
operating results and financial condition. See "Allegro--Allegro Business."
 
     Development cycles for Allegro's and SPC's products typically range between
six to twenty-four months, and have product life cycles of three to thirty-six
months before becoming less productive backlist titles. In light of these
factors, continuing new product development of successful titles will be
necessary for the Combined Company to fulfill its expansion strategy, become
profitable and achieve its objective of becoming a significant publisher of
software for the corporate and SOHO markets. No assurance can be given that the
Combined Company will select or be able to obtain electronic publishing rights
to appropriate content, develop its titles expeditiously or achieve market
acceptance of its titles during their product life. See "Allegro--Allegro
Business."
 
RISKS OF LITIGATION AND POTENTIAL LITIGATION
 
     Competitors and potential competitors of the Combined Company may resort to
litigation as a means of competition. Such litigation may be costly and expose
the Combined Company to new claims that it may not have anticipated. Although
patent and intellectual property disputes in the software area have often been
settled through licensing, cross-licensing or similar arrangements, costs
associated with such arrangements may be substantial if they may be obtained at
all. Any litigation involving the Combined Company, whether as plaintiff or
defendant, regardless of the outcome, may result in substantial costs and
expenses to the Combined Company and significant diversion of effort by the
Combined Company's technical and management
 
                                       23
<PAGE>   32
 
personnel. In addition, there can be no assurance that litigation, either
instituted by or against the Combined Company, will not be necessary to resolve
issues that may arise from time to time in the future with other competitors.
Any such litigation could have a material adverse effect upon the Combined
Company's business, operating results and financial condition.
 
     In the event of an adverse result in any such litigation, the Combined
Company could be required to expend significant resources to develop
noninfringing technology or to obtain licenses to the technology which is the
subject of the litigation. There can be no assurance that the Combined Company
would be successful in such development or that any such licenses would be
available.
 
     If California Proposition 211, "Attorney-Client Fee Arrangement, Securities
Fraud" ("Proposition 211") is approved by the California electorate on November
5, 1996, it may result in an increase generally in class-action lawsuits against
publicly-traded companies having a California presence by shareholders alleging
violations of certain laws relating to securities fraud. Proposition 211 creates
a new cause of action for securities fraud, expands the universe of potential
defendants, lowers the showing of proof required of plaintiffs by lowering the
prior intent or scienter requirement and allowing a plaintiff to sue for fraud
without alleging actual reliance on the purported misrepresentations,
substantially increases the showing of proof for rebuttal purposes required of
defendants, provides for the award of punitive damages, and provides for the
award of attorneys' fees to the prevailing party in the event of the frivolous
prosecution or defense of such a lawsuit. Moreover, Proposition 211 reduces the
circumstances in which principal executive officers, directors and controlling
persons of corporations may be indemnified by the target corporation in
connection with such litigation. Although Proposition 211 would be enacted under
California law and would be applicable to corporations organized under the laws
of California, if enacted, some or all of its provisions may be found by a court
to be applicable to corporations which are organized under the laws of other
states, but which have sufficient contacts with California (such as a principal
place of business in California) to establish the jurisdiction of the state or
federal courts located in California. These and other questions relating to the
interpretation and scope of Proposition 211 may result in lengthy litigation,
including appellate review, creating uncertainty in the law until such
litigation is resolved. Until these questions are resolved, and unless the scope
of Proposition 211 is reduced by the courts, which cannot be assured,
corporations doing business in California, such as the Combined Company, may be
subject to a greater risk of being sued for securities fraud, may encounter
significantly more difficulty in obtaining the services of qualified individuals
to serve as their principal executive officers and directors and may be
adversely affected by a decrease in the availability and increase in the cost of
directors' and officers' liability insurance.
 
INTERNATIONAL SALES; CURRENCY FLUCTUATIONS
 
     International sales have become a significant source of revenue for Allegro
since its acquisition of Serif. International sales represented approximately
34% of SPC's total revenues for the fiscal year ended September 30, 1996. Each
of Allegro and SPC believes that continued profitability will require additional
expansion of sales in foreign markets. This expansion has required and will
continue to require significant management attention and financial resources and
could adversely affect the Combined Company's operating margins. In order to
increase international sales in subsequent periods, the Combined Company may be
required to establish additional foreign operations, hire additional personnel
and recruit additional international resellers. To the extent that the Combined
Company is unable to expand international sales in a timely and cost-effective
manner, its business, operating results and financial condition could be
materially adversely affected. In addition, there can be no assurance that the
Combined Company will be able to maintain or increase international market
demand for its products. Allegro's and SPC's international sales are currently
denominated in either U.S. or local currency and Allegro does not currently
engage in any hedging activities, while SPC has historically engaged in certain
minor hedging activities. Although exposure to currency fluctuations to date has
not been significant, there can be no assurance that fluctuations in the
currency exchange rates in the future will not have a material adverse impact on
the Combined Company's business, operating results and financial condition.
Additional risks inherent in the Combined Company's international business
activities include unexpected changes in regulatory requirements, tariffs and
other trade barriers, costs of localizing products for foreign countries, lack
of acceptance of localized products in foreign countries,
 
                                       24
<PAGE>   33
 
longer accounts receivable payment cycles, difficulties in collecting payment,
difficulties in managing international operations, potentially adverse tax
consequences including repatriation of earnings, reduced protection for
intellectual property, the burdens of complying with a wide variety of foreign
laws, and the effects of high local wage scales and other expenses. There can be
no assurance that such factors will not have a material adverse effect on the
Combined Company's future international sales and, consequently, the Combined
Company's business, operating results and financial condition.
 
DEPENDENCE ON PROPRIETARY TECHNOLOGY; RISK OF THIRD PARTY CLAIMS FOR
INFRINGEMENT
 
     Allegro and SPC rely on a combination of patent, copyright and trademark
laws, trade secrets, confidentiality procedures and contractual provisions to
protect their respective proprietary rights. Despite such efforts to protect
their proprietary rights, unauthorized parties may attempt to copy aspects of
Allegro's or SPC's products or to obtain and use information that Allegro or SPC
regards as proprietary. Policing unauthorized use of Allegro's or SPC's products
is difficult, time-consuming and costly. Although neither Allegro nor SPC is
able to determine the extent to which piracy of its software products exists,
software piracy can be expected to be a persistent problem. In selling its
products, Allegro and SPC have relied on "shrink wrap" licenses that are not
signed by licensees and, therefore, may be unenforceable under the laws of
certain jurisdictions. In addition, the laws of some foreign countries do not
protect proprietary rights to as great an extent as do the laws of the United
States. There can be no assurance that the Combined Company's means of
protecting its proprietary rights will be adequate, or that its competitors will
not independently develop similar technology. Allegro and SPC expect that
software product developers will be increasingly subject to infringement claims
as the number of products and competitors in their industry segments grows and
the functionality of products in different industry segments overlaps. There can
be no assurance that infringement or invalidity claims (or claims for
indemnification resulting from infringement claims) will not be asserted against
the Combined Company, or that any such assertions will not materially adversely
affect its business, operating results and financial condition. Any such claims,
whether with or without merit, could be time-consuming, result in costly
litigation and diversion of resources, cause product shipment delays or require
the Combined Company to enter into royalty or licensing agreements. Such royalty
or licensing agreements, if required, may not be available on terms acceptable
to the Combined Company or at all. In the event of a successful claim of product
infringement against the Combined Company and failure or inability of the
Combined Company to license the infringed or similar technology, the Combined
Company's business, operating results and financial condition could be
materially adversely affected. See "--Risks of Litigation and Potential
Litigation."
 
     Each of Allegro and SPC also relies on certain software that it licenses or
has licensed from third parties, including software that is integrated with
internally developed software and used in its products to perform key functions.
There can be no assurance that these third-party software licenses will continue
to be available to the Combined Company on commercially reasonable terms, or
that the software will be appropriately supported, maintained or enhanced by the
licensors. The loss of or inability to obtain licenses to, or inability to
support, maintain and enhance, any of such software, could result in increased
costs, or in delays or reductions in product shipments until equivalent software
could be developed, identified, licensed and integrated, which could materially
adversely affect the Combined Company's business, operating results and
financial condition.
 
VOLATILITY OF STOCK PRICES
 
     The markets for Allegro's and SPC's common stock are highly volatile. The
trading price of the Combined Company's common stock could be subject to wide
fluctuations in response to quarterly variations in operating and financial
results, announcements of technological innovations or new products by the
Combined Company or its competitors, changes in prices of the Combined Company's
or its competitors' products and services, changes in product mix, changes in
revenue and revenue growth rates for the Combined Company as a whole or for
individual geographic areas, business units, products or product categories, as
well as other events or factors. Statements or changes in opinions, ratings, or
earnings estimates made by brokerage firms or industry analysts relating to the
market in which the Combined Company does business or relating to Allegro, SPC,
or the Combined Company could result in an immediate and adverse effect on the
market price
 
                                       25
<PAGE>   34
 
of Allegro's or SPC's common stock. Statements by financial or industry analysts
regarding the extent of the dilution in Allegro's net income (loss) per share,
revenue per share, or other similar measure resulting from the Merger and the
extent to which such analysts expect potential business synergies to offset such
dilution can be expected to contribute to volatility in the market price of the
Allegro Common Stock. In addition, the stock market has from time to time
experienced extreme price and volume fluctuations which have particularly
affected the market price for the securities of many software companies and
which often have been unrelated to the operating performance of these companies.
These broad market fluctuations may adversely affect the market price of the
Allegro Common Stock.
 
SEASONALITY
 
     The computer software market is characterized by significant seasonal
swings in demand, which typically peak in the fourth quarter of each calendar
year. The seasonal pattern is due primarily to the increased demand for software
during the year-end holiday buying season and reduced retail and corporate
demand for business software during the European summer holiday period. Allegro
and SPC expect that the Combined Company's net sales and operating results to
continue to reflect this seasonality. The Combined Company's revenues may also
experience substantial variations as a result of a number of factors, such as
consumer and business preferences and introduction of competing titles by
competitors, as well as limited time promotional pricing offers. There can be no
assurance that the Combined Company will achieve consistent profitability on a
quarterly or annual basis. See "Allegro Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
DISTRIBUTION; DEPENDENCE ON RETAILERS, DISTRIBUTORS AND SALES REPRESENTATIVES
 
     Allegro and SPC sell their products to distributors for resale to retailers
and directly to retailers, OEMs and end-users. Allegro's and SPC's retail
customers include office supply stores, software specialty stores, computer
superstores, bookstores, warehouse clubs, consumer electronics stores,
mall-based chains and mass merchants. Allegro's and SPC's customers are not
contractually required to make future purchases of their products and therefore
could discontinue carrying their products in favor of a competitor's product or
for any other reason. Retailers and distributors compete in a volatile industry
that is subject to rapid change, consolidation, financial difficulty and
increasing competition from new distribution channels. Due to increased
competition for limited shelf space, retailers and distributors are increasingly
in a better position to negotiate favorable terms of sale, including price
discounts and product return policies. Retailers often require software
publishers to pay fees in exchange for preferred shelf space. Retailers may give
higher priority to products other than those of Allegro and SPC, thus reducing
their efforts to sell Allegro's and SPC's products. There can be no assurance
that the Combined Company will be able to increase or sustain the current amount
of retail shelf space held by Allegro and SPC, and as a result, the Combined
Company's operating results could be adversely affected. In addition, other
types of retail outlets and methods of product distribution may become important
in the future, such as the Internet and on-line services. It is critical to the
success of the Combined Company that as these changes occur, it gains access to
those channels of distribution; however, no assurance can be given that the
Combined Company will successfully do so. Allegro and SPC have established
internal marketing and distribution capabilities which they utilize for their
products, and also utilize distributors and independent computer software and
bookstore sales representatives. Allegro and SPC also utilize direct mail and
related telesales efforts to sell their products. Allegro's and SPC's
independent sales representatives, who have been retained to service different
geographic regions of the United States on a non-exclusive, commission only
basis, sell products of other vendors. These representatives may elect to sell,
devote greater time and energy to other products generally, or to products that
provide them with greater commission dollars. Although Allegro's and SPC's
personnel are experienced in the distribution of software products, there can be
no assurance that the Combined Company will be successful in marketing and
distributing its products. See "Allegro--Allegro Business" and "SPC--SPC
Business."
 
CUSTOMER CONCENTRATION AND CREDIT RISK
 
     In 1995, Allegro had two customers, Navarre Corp. and Ingram Micro, Inc.,
each of whom accounted for more than 10% of sales (gross sales less provisions
for returns) and which in the aggregate accounted for
 
                                       26
<PAGE>   35
 
approximately 36% of sales. For the nine-month period ended September 30, 1996,
Navarre Corp. and Ingram Micro, Inc., each of whom accounted for more than 10%
of sales, in the aggregate accounted for approximately 25% of its sales. In
addition, Allegro's five largest customers collectively represented
approximately 55% of sales in the fiscal year ended December 31, 1995 and
approximately 39% of sales in the nine-month period ended September 30, 1996. In
fiscal year 1995, SPC had one customer, Ingram Micro, Inc. which accounted for
more than 10% of SPC's net revenues and which accounted for approximately 31% of
net revenues and 46% of SPC's net outstanding accounts receivable at September
30, 1995. In fiscal year 1996, SPC had one customer, Ingram Micro, Inc., which
accounted for more than 10% of SPC's net revenues and which accounted for
approximately 19% of net revenues and 38% of net outstanding accounts receivable
at September 30, 1996. The loss of any of the Combined Company's major
customers, a significant decrease in product shipments to one or more of them,
or an inability to collect receivables from one or more of them could adversely
affect the Combined Company's business, operating results and financial
condition. See "Allegro Management's Discussion and Analysis of Financial
Condition and Results of Operations," "Allegro--Allegro Business," "SPC
Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "SPC--SPC Business."
 
PRODUCT RETURNS; COLLECTION OF ACCOUNTS RECEIVABLE
 
     Consistent with industry practices, the Combined Company may accept product
returns or provide other credits in the event that a retailer or distributor
holds excess inventory of the Combined Company's products, even when the
Combined Company is not legally required to do to. The Combined Company's sales
will be made on credit terms which may vary substantially and it will not hold
collateral to secure payment. Therefore, a default in payment on a significant
scale could adversely affect the Combined Company's business, results of
operations and financial condition. It is difficult for Allegro and SPC to
ascertain current demand for their existing products and anticipated demand for
newly introduced products. Accordingly, the Combined Company will be exposed to
the risk of product returns from retailers and distributors. While Allegro and
SPC believe that they each have established appropriate allowances for
anticipated returns based on its historical experience, there can be no
assurance that actual returns and uncollectible receivables will not exceed such
allowances. Defective products also may result in higher customer support costs
and product returns. Any significant increase in product returns or uncollected
accounts receivable beyond reserves could have a material adverse effect on the
Combined Company's business, results of operations and financial conditions. See
"Allegro Management's Discussion and Analysis of Financial Condition and Results
of Operations" and "Allegro--Allegro Business," "SPC Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "SPC--SPC
Business."
 
CERTAIN TAX CONSIDERATIONS
 
     Allegro estimates its consolidated tax net operating loss carryforwards to
be approximately $10.2 million at September 30, 1996. SPC estimates its
consolidated tax net operating loss carryforwards to be approximately $69
million at September 30, 1996. Under Section 382 of the Code, certain changes in
the ownership or the business of a corporation that has net operating loss
carryforwards will result in the inability to use or the imposition of
significant restrictions on the use of such net operating loss carryforwards to
offset future income and tax liability of such corporation. Allegro and SPC
expect that after giving effect to the Merger, an "ownership change" will be
deemed to have occurred under Section 382 of the Code and the regulations
thereunder with respect to both Allegro and SPC, and that as a result thereof
the use by the Combined Company of the net operating loss carryforwards of
Allegro and SPC will be limited. Utilization of the net operating loss
carryforwards of SPC may be further limited by reason of the consolidated return
separate return limitation year rules. There can be no assurance that the
Combined Company will be able to utilize all or any net operating loss
carryforwards of SPC or Allegro. In addition, the foreign losses incurred by SPC
may decrease or otherwise restrict the ability of the Combined Company to claim
U.S. tax credits for foreign income taxes. At or after the Effective Time,
Allegro expects to enter into a closing agreement with the Internal Revenue
Service pursuant to which Allegro would become jointly and severally liable for
SPC's tax obligations upon occurrence of a "triggering event" requiring
recapture of dual consolidated losses previously utilized by SPC. Such closing
agreement will avoid SPC being required to recognize a tax on approximately
 
                                       27
<PAGE>   36
 
$24.5 million of SPC's previous dual consolidated losses at the Effective Time.
Any future acquiror of the Combined Company may also be required to agree to a
similar closing agreement, to the extent it is able to do so. Non-U.S. persons
generally would be ineligible to do so. This could have a material adverse
effect on the future ability of the Combined Company to sell SPC to such an
ineligible person. See "Approval of the Merger and Related Transactions--Net
Operating Loss Carryforwards."
 
DEPENDENCE ON EXTERNAL DEVELOPMENT RESOURCES
 
     Allegro has relied on external development resources for the development of
a significant number of the software products it publishes. The Combined Company
may be dependent on the services of freelance software developers, consultants,
programmers and product designers with respect to certain of its products. As
independent developers are in high demand, there can be no assurance that
independent developers, including those which have developed products for
Allegro or SPC in the past, will be available to develop products for the
Combined Company in the future. Many independent developers have limited
financial resources, which could expose the Combined Company to the risk that
such developers may go out of business prior to completing a project. In
addition, due to the fact that the Combined Company may have less control over
the scheduling and quality of the work of independent developers than it does
over its own employees, there can be no assurance that such developers will
complete products for the Combined Company on a timely basis, within acceptable
guidelines, or at all. The Combined Company's success may also be dependent on
its ability to obtain content for its products from external sources. There can
be no assurance that the Combined Company will be able to obtain or renew
product content license agreements, or to obtain such content, on favorable
terms, or at all. See "Allegro -- Allegro Business."
 
POTENTIAL ANTI-TAKEOVER EFFECTS OF DELAWARE LAW AND CERTIFICATE OF
INCORPORATION; POSSIBLE ISSUANCES OF PREFERRED STOCK
 
     Certain provisions of Delaware law and Allegro's Certificate of
Incorporation could make more difficult a merger, tender offer or proxy contest
involving Allegro, even if such events could be beneficial to the interests of
the stockholders. These provisions include Section 203 of the Delaware General
Corporation Law, the classification of Allegro's Board of Directors into three
classes, the requirement that 66 2/3% of the stockholders of the Combined
Company request a special meeting of stockholders (other than a special meeting
called by the Board of Directors or the President of the Combined Company), the
provisions of the employment agreements and other agreements referred to under
"Allegro Management and Executive Compensation-- Employment Agreements", and the
requirement that 66 2/3% of the stockholders of Allegro entitled to vote thereon
approve certain transactions, including mergers and sales or transfers of all or
substantially all of the assets of Allegro to "interested persons" as defined in
Section 203 of the Delaware General Corporation Law. Such provisions could limit
the price that certain investors might be willing to pay in the future for
shares of Allegro's capital stock. In addition, shares of preferred stock may be
issued by the Allegro Board of Directors without stockholder approval on such
terms as the Allegro Board may determine. The rights of the holders of Allegro
Common Stock will be subject to, and may be adversely affected by, the rights of
the holders of additional or other classes of preferred stock that may be issued
in the future. Moreover, although the ability to issue other classes of
preferred stock may provide flexibility in connection with possible acquisitions
and other corporate purposes, such issuance may make it more difficult for a
third party to acquire, or may discourage a third party from acquiring, a
majority of the voting stock of the Combined Company. See "Comparison of Capital
Stock."
 
DIRECTORS' LIABILITY LIMITED
 
     Allegro's Certificate of Incorporation provides (and the Combined Company's
certificate of incorporation will provide) that its directors (but not its
officers) will not be held liable to the Combined Company or its
 
                                       28
<PAGE>   37
 
stockholders for monetary damages upon breach of a director's fiduciary duty,
except to the extent otherwise required by law.
 
NO DIVIDENDS
 
     Allegro has never paid any cash dividends on its Allegro Common Stock and
the Combined Company does not anticipate paying any dividends in the foreseeable
future.
 
CONTRACTUAL OBLIGATIONS TO MS FARRELL
 
     Allegro has agreed to pay fees to MS Farrell if MS Farrell arranges mergers
and acquisitions, joint ventures or other business transactions for Allegro
(other than the Merger and this related offering) until December 2000. Such fees
may reduce the amount of proceeds available to the Combined Company from such
transactions. Allegro and its officers and directors have agreed that MS Farrell
shall have a right of first refusal until December 2000 with respect to the
placement of any securities to be sold by the Combined Company, any subsidiary
or successor of the Combined Company or, subject to certain exceptions, by any
holder of 5% or more of the Combined Company's securities. In addition, Allegro
has agreed that until the earlier of December 2000 or the exercise of 75% of the
Underwriter's Purchase Options for 103,300 shares of Allegro Common Stock issued
in connection with the IPO, Allegro (which after the Merger is the Combined
Company) will not issue any shares of its Allegro Common Stock or securities
convertible into shares of Allegro Common Stock at a price per share less than
80% of the fair market value of the Allegro Common Stock (as defined) unless
such issuance is approved by at least three-quarters of the members of the
Combined Company's Board of Directors present at a meeting, including the
designee of MS Farrell serving on the Combined Company's Board of Directors. See
"Allegro Certain Transactions." Such requirements may limit the Combined
Company's ability to issue securities.
 
POSSIBLE ISSUANCE OF SUBSTANTIAL AMOUNTS OF ADDITIONAL SHARES WITHOUT
STOCKHOLDER APPROVAL
 
     After this offering, the Combined Company will have an aggregate of
approximately 22,165,431 shares of Allegro Common Stock (assuming the approval
of proposal number (2)) and 1,939,480 shares of Serial Preferred Stock
authorized but unissued and not reserved for specific purposes, and assuming the
approval of Allegro proposal number (4), an additional 3,179,771 shares of
Allegro Common Stock unissued but reserved for issuance pursuant to (i)
Allegro's 1994 Incentive Plan, (ii) Allegro's Outside Director and Advisor Plan,
(iii) the Underwriters' Purchase Option issued in connection with Allegro's IPO,
(iv) an option to purchase 100,000 shares of Allegro Common Stock granted to
Berlitz Publishing Company (the "Berlitz Option"), (v) certain warrants granted
to MS Farrell and its designees (the "MS Farrell Warrants"), and (vi) the SPC
Stock Option Plans. In the event that proposal number (3) eliminating Allegro's
Class A Convertible Preferred Stock is not approved, the Combined Company will
also have 2,000,000 shares of Class A Convertible Preferred Stock authorized but
unissued and not reserved for specific purposes. All of such shares may be
issued without any action or approval by Allegro's stockholders. Although there
are no other present plans, agreements, commitments or undertakings with respect
to the issuance of additional shares or securities convertible into any such
shares by the Combined Company, other than in connection with the Berlitz
Option, the Underwriter's Purchase Option or the MS Farrell Warrants if
exercised, any shares issued would further dilute the percentage ownership of
the Combined Company held by the stockholders of SPC. See "Allegro Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
     While the Combined Company has no present plans to issue any additional
shares of preferred stock, the Board of Directors has the authority, without
stockholder approval, to create and issue one or more series of such preferred
stock and to determine the voting, dividend and other rights of holders of such
preferred stock. The issuance of any of such series of preferred stock could
have an adverse effect on the holders of Allegro Common Stock. See "Comparison
of Capital Stock--Description of Allegro Capital Stock."

<PAGE>   38
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     The sale of any substantial number of shares of Allegro Common Stock can be
expected to have a depressive effect on the market price of the Allegro Common
Stock. As of October 28, 1996, approximately 1,060,000 of the shares of
Allegro's Common Stock outstanding are eligible for resale under Rule 144, and
would be available for sale in the public market, subject to the quantity
limitations set forth in Rule 144; however, certain of Allegro's officers and
directors, as well as holders of all but approximately 42,000 of these shares of
Allegro Common Stock, have agreed not to sell any of their shares until December
1997 without the prior consent of MS Farrell. The holders of an aggregate of
243,902 shares of Allegro Common Stock and MS Farrell with respect to 103,300
shares of Allegro Common Stock underlying the Underwriter's Purchase Option have
demand and piggyback registration rights with respect to such shares, MS Farrell
and one of its managing directors have piggyback registration rights with
respect to the 500,000 shares of Allegro Common Stock underlying the MS Farrell
Warrants, and BizEd, Inc., Clifford Schorrer and their transferees have
piggyback registration rights with respect to the 17,273 shares of Allegro
Common Stock issued to them in connection with a purchase of certain assets. In
addition, Allegro has agreed to register as part of the next registration
statement filed by Allegro after the Merger, the shares of Allegro Common Stock
issuable to Unterberg Harris in partial payment of their fees for providing
investment banking services in connection with the Merger and the shares of
Allegro Common Stock issuable to Frost Capital Partners, Inc. in partial payment
of their fees for providing investment banking services in connection with the
Merger and in connection with Allegro's acquisition of Serif, the amount of
which shares will be based on the price of Allegro Common Stock at the Effective
Time. Upon the inclusion of the foregoing shares of Allegro Common Stock in any
future registration statement by Allegro, such shares could be sold in the
market.

                    ALLEGRO NEW MEDIA, INC. SPECIAL MEETING
 
DATE, TIME AND PLACE OF ALLEGRO MEETING
 
     The Allegro Meeting will be held at           , New Jersey, on           ,
          , 1996 at           , local time.
 
PURPOSE
 
     The purpose of the Allegro Meeting is to approve (1) the Agreement and the
Merger, (2) an amendment to the Certificate to increase the number of shares of
Allegro Common Stock authorized to be issued from 18,000,000 to 30,000,000,
subject to and upon consummation of the Merger, (3) an amendment to the
Certificate of Allegro to eliminate the Class A Convertible Preferred Stock, the
outstanding shares of which have been converted into shares of Common Stock; and
(4) an amendment to the Allegro Incentive Plan to increase by 2,000,000 to
3,000,000 the number of shares to be available for grant and reserved for
issuance under the Allegro Incentive Plan (which increase represents
approximately 20.3% of the shares of Allegro Common Stock estimated to be
outstanding or issuable following consummation of the Merger based on the
capitalization of Allegro and SPC as of October 1, 1996), subject to and upon
consummation of the Merger.
 
     In determining whether to vote in favor of proposal (1), stockholders
should be aware that the terms of the Agreement provide that in the event that
the stockholders of Allegro fail to approve the Merger, Allegro is required to
pay to SPC the sum of $750,000.
 
RECORD DATE AND OUTSTANDING SHARES
 
     Only Allegro stockholders of record at the close of business on           ,
1996 (the "Allegro Record Date") are entitled to notice of and to vote at the
Allegro Meeting. As of the Allegro Record Date, there were
stockholders of record of Allegro Common Stock and one stockholder of record of
Allegro's Class B Voting Preferred Stock.
 
     On or about           , 1996, a notice meeting the requirements of Delaware
law is being mailed to all stockholders of record as of the Allegro Record Date.
 
VOTE REQUIRED
 
     Under Delaware law and the charter documents of Allegro, approval of (a)
the amendment to the Certificate increasing the number of shares of authorized
Common Stock requires the affirmative vote of holders of a majority of the
outstanding shares of Allegro Common Stock and the affirmative vote of holders
of a majority of the outstanding shares of Class B Voting Preferred Stock, each
voting as a separate class, (b) the amendment to the Certificate eliminating the
Class A Convertible Preferred Stock requires the affirmative vote of a majority
of outstanding shares of Allegro Common Stock and Class B Voting Preferred Stock
voting together as one class, and (c) the amendment to the Allegro Incentive
Plan requires the affirmative vote of a majority of the total votes cast
regarding such proposal, with the Allegro Common Stock and Class B Voting
Preferred Stock voting together as a class. Approval of the Agreement and the
Merger is not required; nevertheless, the Board of Directors of Allegro has
determined to seek the affirmative vote of a majority of the total votes cast on
this matter by the holders of Allegro Common Stock and Class B Voting Preferred
Stock, voting together as a class, regarding the proposal to approve the
Agreement and the Merger.
 
                                       31
<PAGE>   40
 
Each stockholder of record of Allegro Common Stock on the Allegro Record Date is
entitled to cast one vote per share, exercisable in person or by properly
executed proxy, on each matter properly submitted for the vote of the
stockholders of Allegro at the Allegro Meeting. In addition, as of the Allegro
Record Date, Barry A. Cinnamon held of record 60,520 votes of Allegro Class B
Voting Preferred Stock, each of which will be entitled to cast 10 votes on each
matter to be acted upon at the Allegro Meeting. As of the Allegro Record Date,
the directors and executive officers of Allegro and their affiliates owned an
aggregate of approximately    % of the issued and outstanding Allegro Common
Stock and held approximately    % of the voting power (including the Class B
Voting Preferred Stock) of Allegro.
 
     The presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of each of the Allegro Common Stock and the
Class B Voting Preferred Stock shall constitute a quorum for proposals (2) and
(3), and the presence, in person or by properly executed proxy, of the holders
of a majority of the outstanding shares of Allegro Common Stock and Class B
Voting Preferred Stock entitled to vote at the Allegro Meeting, in the
aggregate, shall constitute a quorum for proposals (1) and (4). For purposes of
determining whether proposals have received a majority vote, abstentions will
not be included in the vote totals and, in instances where brokers are
prohibited from exercising discretionary authority for beneficial owners who
have not returned a proxy (so called "broker non-votes"), those votes will not
be included in the vote totals. Therefore, the effect of an abstention is the
same as that of a vote "against" the proposal with regard to proposals (2) and
(3) , while abstentions and broker non-votes will have no effect on the vote,
but will be counted in the determination of a quorum, for purposes of proposals
(1) and (4).
 
PROXIES
 
     Each of the persons named as proxies in the proxy is an officer of Allegro.
All shares of Allegro Common Stock that are entitled to vote and are represented
at the Allegro Meeting either in person or by properly executed proxies received
prior to or at the Allegro Meeting and not duly and timely revoked will be voted
at the Allegro Meeting in accordance with the instructions indicated on such
proxies. If no such instructions are indicated, such proxies will be voted for
the approval of the Agreement and Merger, the amendments of the Certificate and
the amendment to the Allegro Incentive Plan.
 
     The Allegro Board knows of no other matter to be presented at the Allegro
Meeting. If any other matters are properly presented for consideration at the
Allegro Meeting (or any adjournments or postponements thereof) including, among
other things, consideration of a motion to adjourn or postpone the Allegro
Meeting to another time and/or place (including, without limitation, for the
purpose of soliciting additional proxies), the persons named in the enclosed
forms of proxy and voting thereunder will have the discretion to vote on such
matters in accordance with their best judgment.
 
     Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked by (i) filing
with the Secretary of Allegro at or before the taking of the vote at the Allegro
Meeting, a written notice of revocation bearing a later date than the proxy;
(ii) duly executing a later-dated proxy relating to the same shares and
delivering it to the Secretary of Allegro before the taking of the vote at the
Allegro Meeting or (iii) attending the Allegro Meeting and voting in person
(although attendance at the Allegro Meeting will not in and of itself constitute
a revocation of a proxy). Any written notice of revocation or subsequent proxy
should be sent so as to be delivered to Allegro New Media, Inc. at 3 Oak Road,
Fairfield, New Jersey 07004, Attention: Secretary, or hand-delivered to the
Secretary of Allegro, in each case at or before the taking of the vote at the
Allegro Meeting.
 
SOLICITATION OF PROXIES; EXPENSES
 
     The cost of the solicitation of Allegro stockholders will be borne by
Allegro. In addition, Allegro may reimburse brokerage firms and other persons
representing beneficial owners of shares for their expenses in forwarding
solicitation materials to such beneficial owners. Proxies may also be solicited
by certain Allegro directors, officers and regular employees personally or by
telephone, telegram, letter or facsimile. Such persons will not receive
additional compensation, but may be reimbursed for reasonable out-of-pocket
expenses incurred in connection with such solicitation. In addition, Allegro may
retain a proxy solicitor to assist in the
 
                                       32
<PAGE>   41
 
solicitation of proxies, the cost of which would be anticipated to be
approximately $5,000 plus reimbursement of reasonable expenses.
 
RECOMMENDATIONS OF ALLEGRO BOARD OF DIRECTORS
 
     THE ALLEGRO BOARD HAS UNANIMOUSLY APPROVED THE AGREEMENT AND THE MERGER AND
HAS DETERMINED THAT THE MERGER IS FAIR AND IN THE BEST INTERESTS OF ALLEGRO AND
ITS STOCKHOLDERS. AFTER CAREFUL CONSIDERATION, THE ALLEGRO BOARD UNANIMOUSLY
RECOMMENDS A VOTE IN FAVOR OF (i) THE APPROVAL OF THE AGREEMENT AND THE MERGER,
(ii) AN AMENDMENT TO THE CERTIFICATE TO INCREASE THE NUMBER OF SHARES OF ALLEGRO
COMMON STOCK AUTHORIZED TO BE ISSUED FROM 18,000,000 TO 30,000,000, SUBJECT TO
AND UPON CONSUMMATION OF THE MERGER, (iii) AN AMENDMENT TO THE CERTIFICATE TO
ELIMINATE THE CLASS A CONVERTIBLE PREFERRED STOCK AND (IV) AN AMENDMENT TO THE
ALLEGRO INCENTIVE PLAN TO INCREASE BY 2,000,000 TO 3,000,000 THE NUMBER OF
SHARES TO BE AVAILABLE FOR GRANT AND RESERVED FOR ISSUANCE UNDER THE ALLEGRO
INCENTIVE PLAN, SUBJECT TO AND UPON CONSUMMATION OF THE MERGER.

                SOFTWARE PUBLISHING CORPORATION SPECIAL MEETING
 
DATE, TIME AND PLACE OF SPC MEETING
 
     The SPC Meeting will be held at the offices of SPC located at 111 North
Market Street, San Jose, California 95113, on           ,           , 1996 at
          a.m., local time.
 
PURPOSE
 
     The purposes of the SPC Meeting are to approve the Agreement and the Merger
and to transact such other matters as may properly come before the SPC Meeting
or any postponements or adjournments thereof.
 
     In determining whether to vote in favor of the proposal, stockholders
should be aware that the terms of the Agreement provide that (i) if the
stockholders of SPC fail to approve the Merger following a publicly disclosed
(and not withdrawn) Acquisition Proposal (as defined) with regard to SPC or if
the stockholders of SPC fail to approve the Merger following the withholding,
withdrawal or modification by the Board of Directors of SPC, in a manner adverse
to Allegro, of its recommendation in favor of the Merger, then SPC will
immediately pay to Allegro the sum of $1 million and (ii) if the stockholders of
SPC fail to approve the Merger under circumstances not described in the
preceding clause, SPC is required to pay to Allegro the sum of $750,000.
 
RECORD DATE AND OUTSTANDING SHARES
 
     Only stockholders of record of SPC Common Stock at the close of business on
          1996 (the "SPC Record Date") are entitled to notice of, and to vote
at, the SPC Meeting. As of the SPC Record Date, there were
stockholders of record holding an aggregate of approximately [12,582,820] shares
of SPC Common Stock.
 
     On or about           , 1996, a notice meeting the requirements of Delaware
law is being mailed to all stockholders of record as of the SPC Record Date.
 
VOTE REQUIRED
 
     Pursuant to the Delaware General Corporation Law and the SPC Certificate of
Incorporation, as amended, the affirmative vote of the holders of a majority of
the SPC Common Stock outstanding as of the SPC Record Date is required to
approve and adopt the Agreement. Each stockholder of record of SPC Common Stock
on the SPC Record Date, will be entitled to cast one vote per share on each
matter to be acted upon at the SPC Meeting.
 
     The representation, in person or by proxy, of at least a majority of the
outstanding shares of SPC Common Stock entitled to vote at the SPC Meeting is
necessary to constitute a quorum for the transaction of business. The effect of
an abstention is the same as that of a vote "against" the proposal.
 
PROXIES
 
     Each of the persons named as proxies for the SPC Meeting is an officer of
SPC. All shares of SPC Common Stock that are entitled to vote and are
represented at the SPC Meeting either in person or by properly executed proxies
received prior to or at the SPC Meeting and not duly and timely revoked will be
voted at the SPC Meeting in accordance with the instructions indicated on such
proxies. If no such instructions are indicated, such proxies will be voted for
the approval of the Agreement.
 
     The SPC Board knows of no other matter to be presented at the SPC Meeting.
If any other matter upon which a vote may properly be taken should be presented
at the SPC Meeting, shares represented by all proxies received by the SPC Board
will be voted with respect thereto in accordance with the judgement of the
persons named as proxies in the proxies.
 
     Execution of a proxy does not in any way affect a stockholder's right to
attend the meeting and vote in person. Any proxy may be revoked by a stockholder
at any time before it is exercised by delivering a written
 
                                       34

revocation or a later-dated proxy to the Secretary of SPC, or by attending the
meeting and voting in person. Any written notice of revocation or subsequent
proxy should be sent so as to be delivered to Software Publishing Corporation at
111 North Market Street, San Jose, California 95113, Attention: Secretary, or

the vote at the SPC Meeting.
 
SOLICITATION OF PROXIES; EXPENSES
 
     All costs of solicitation of proxies for the SPC Meeting will be borne by
SPC. Brokers, custodians and fiduciaries will be requested to forward proxy
soliciting material to the owners of stock held in their names, and SPC will
reimburse them for their reasonable out-of-pocket costs. In addition, proxies
may also be solicited by certain directors, officers and employees of SPC
personally or by mail, telephone or telegraph following the original
solicitation. Such persons will not receive additional compensation for such
solicitation. SPC has retained Corporate Investor Communications, Inc., an
independent proxy solicitation firm, to assist in soliciting proxies at an
estimated fee of $5,000 plus reimbursement of reasonable expenses.

PROVISIONS OF THE AGREEMENT AND RELATED AGREEMENTS. DETAILED TERMS OF AND
CONDITIONS TO THE MERGER AND CERTAIN RELATED TRANSACTIONS ARE CONTAINED IN THE

INVOLVE RISKS AND UNCERTAINTIES. ACTUAL RESULTS COULD DIFFER MATERIALLY FROM
THOSE ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT OF A VARIETY

JOINT REASONS FOR THE MERGER
 
     The Boards of Directors of SPC and Allegro believe that the Combined
Company will have the potential to realize long-term improved operating and
financial results and a stronger competitive position. Allegro and SPC believe
that there is a strategic fit among the two companies' visual communications and
business productivity software technologies, product offerings and marketing
organizations and that, in order to succeed in the market served by these
business application tools, absent the Merger, each company would need to expand
its product offerings to address a wider range of customer requirements. Allegro
and SPC also believe that the Merger will provide greater opportunities to
develop business relationships, license technology, and engage in other
strategic combinations and transactions involving their respective products and
technologies than would be the case if the companies otherwise independently
engaged in these activities. In this way, the Merger could provide the Combined
Company with the range of products and services required to participate in the
evolving market for visual communications and business productivity software for
the corporate and SOHO computer software markets.
 
     Each of the Boards of Directors of SPC and Allegro has identified
additional potential mutual benefits of the Merger, including the following:
 
     -  The combined experience, financial resources, size and product offerings
       of the Combined Company may allow the Combined Company to respond more
       quickly and effectively to technological change, increased competition
       and market demands in an industry experiencing rapid innovation and
       change.
 
     -  The combination of SPC's visual communications products with Allegro's
       desktop publishing, graphics and other business productivity products may
       allow the Combined Company to offer a more comprehensive and integrated
       set of visual communications and business productivity software tools to
       its customers.
 
     -  The creation of a larger customer base, a higher market profile and
       greater financial strength may present greater opportunities for
       marketing the products of the Combined Company.
 
     -  The structure of the transaction as a "merger of equals" may provide
       significant advantages in increasing the opportunity for (i) effectively
       utilizing the skills and resources of the companies' respective
       management teams and (ii) enhancing some aspects of the respective
       "corporate cultures" of the two companies.
 
     -  The integration of the companies' product lines may enhance the Combined
       Company's ability to increase its penetration of the market for business
       productivity software and other business software tools in the corporate
       and SOHO environment.
 
     -  The companies' combined technological resources may allow the Combined
       Company to compete more effectively against larger competitors by
       providing the Combined Company with enhanced ability to develop new
       products and incorporate greater functionality into existing products.
 
     -  The creation of a combined customer service and technical support system
       may permit the Combined Company to provide more efficient support
       coverage to its customers.

     Allegro and SPC have each identified additional reasons for the Merger.
Each Board of Directors has recognized, however, that the potential benefits of
the Merger may not be realized. See "Risk Factors."
 
ALLEGRO'S REASONS FOR THE MERGER
 
     In addition to the anticipated joint benefits described above, the Allegro
Board believes that the following are additional reasons the Merger will be
beneficial to Allegro and for stockholders of Allegro to vote FOR the proposals
set forth herein:
 
     -  Given the complementary nature of the product lines of Allegro and SPC,
       the Merger may enhance the opportunity for the potential realization of
       Allegro's strategic objective of achieving greater economies of scale and
       presence in the visual communications and business productivity software
       markets.
 
     -  SPC has a sales force and distribution system that are expected to
       complement Allegro's sales and distribution resources. These additional
       sales resources may provide expanded opportunities to market Allegro's
       and SPC's products to new and existing customers.
 
     -  Allegro believes that, absent the Merger, its future success would be
       dependent, in part, on its ability to develop or acquire successful new
       products. Together, Allegro's and SPC's products would be expected to
       provide a more comprehensive line of business productivity software
       tools, and may reduce Allegro's dependence on individual segments of the
       business productivity software market.
 
     -  The combined technological and engineering resources of Allegro and SPC
       would be expected to allow the Combined Company an opportunity to offer
       an integrated package of business productivity software tools that
       perform together to meet customer needs.
 
     -  The Allegro stockholders would have the opportunity to participate in
       the potential for growth of the Combined Company after the Merger.
 
     In the course of its deliberations, during Allegro Board meetings held on
September 26, 1996, September 30, 1996 and October 25, 1996, the Allegro Board
reviewed with Allegro management a number of additional factors relevant to the
Merger, including (i) historical information concerning Allegro's and SPC's
respective business, prospects, financial performance and condition, operations,
technology, management and competitive position, including public reports filed
with the SEC concerning results of operations during the most recent fiscal year
and fiscal quarters for each company; (ii) Allegro management's view as to the
financial condition, results of operations and businesses of Allegro and SPC
before and after giving effect to the Merger based on management's due
diligence; (iii) current financial market conditions and historical market
prices, volatility and trading information with respect to the Allegro Common
Stock and SPC Common Stock; (iv) the consideration to be received by SPC
stockholders in the Merger and the market value of the Allegro Common Stock to
be issued in exchange for the SPC Common Stock; (v) the belief that the terms of
the Agreement, including the parties' representations, warranties and covenants,
and the conditions to their respective obligations, are reasonable; (vi) Allegro
management's view as to the prospects of Allegro as an independent company;
(vii) Allegro management's view as to the potential for other third parties to
enter into strategic relationships with or to acquire Allegro or SPC; (viii) the
impact of the Merger on Allegro's customers and employees; and (ix) reports from
management and financial advisors as to the results of their due diligence
investigation of SPC. The Allegro Board also considered the terms of the
proposed Agreement regarding SPC's right to consider and negotiate other
acquisition proposals in certain circumstances, as well as the possible effects
of the provisions regarding termination fees. In addition, the Allegro Board
noted that the Merger is expected to be accounted for as a purchase, and that
currently the amount of goodwill expected to be created on the books of the
Combined Company cannot be determined. The Allegro Board considered financial
presentations by Frost, including the financial analysis Frost delivered at the
September 30, 1996 and October 25, 1996 meetings of the Allegro Board of
Directors, and set forth in writing as of September 30, 1996, which concluded
that the Exchange Ratio provided in the Agreement was fair to Allegro and its
stockholders from a financial point of view on such date (a copy of this opinion
is annexed hereto, and stockholders are urged to carefully review this opinion).
The Allegro Board also took into
 
                                       37
<PAGE>   46
 
account that Allegro would have significantly greater representation on the
Board of the Combined Company following the Merger.
 
     The Allegro Board also identified and considered a variety of potentially
negative factors in its deliberations concerning the Merger, including, but not
limited to: (i) the risk that the potential benefits sought in the Merger might
not be fully realized, (ii) the possibility that the Merger might not be
consummated and the effect of public announcement of the Merger on (a) Allegro's
sales and operating results, (b) Allegro's ability to attract and retain key
management, marketing and technical personnel and (c) the progress of certain
development projects, (iii) the potential dilutive effect of the issuance of
Allegro Common Stock in the Merger, (iv) the substantial charges to be incurred,
primarily in the quarter in which the Merger is consummated, in connection with
the Merger, including costs of integrating the businesses and transaction
expenses arising from the Merger, (v) the risk that despite the efforts of the
Combined Company, key technical and management personnel might not remain
employed by the Combined Company, (vi) the difficulty of managing separate
operations at different geographic locations and (vii) the other risks described
under "Risk Factors" herein. The Allegro Board believed that these risks were
outweighed by the potential benefits of the Merger.
 
SPC'S REASONS FOR THE MERGER
 
     In addition to the anticipated joint benefits described above, the SPC
Board believes that the following are additional reasons the Merger will be
beneficial to SPC and for stockholders of SPC to vote FOR the proposal set forth
herein:
 
     -  The addition of Allegro's complementary customer base to SPC's existing
       customer base may provide new opportunities to market SPC's products to a
       larger group of business customers.
 
     -  Allegro has a sales force and distribution system that are expected to
       complement SPC's sales and distribution resources. Additional sales
       resources may provide expanded opportunities to market Allegro's and
       SPC's products to new and existing customers.
 
     -  SPC currently derives substantially all of its revenue from Harvard
       Graphics and Intelligent Formatting products. SPC believes that, absent
       the Merger, its continued future success would be dependent, in part, on
       its ability to develop or acquire new products and expand its product
       offerings. Together, Allegro's and SPC's products may be expected to
       provide a more comprehensive line of business productivity software
       tools, and may reduce SPC's dependence on individual segments of the
       business productivity software market.
 
     -  The combined technological and engineering resources of Allegro and SPC
       would be expected to allow the Combined Company an opportunity to offer
       an integrated package of business productivity software tools that
       perform together to meet customer needs.
 
     -  The SPC stockholders would have the opportunity to participate in the
       potential growth of the Combined Company after the Merger.
 
     In the course of its deliberations during SPC Board meetings held on
September 6, 1996, September 13, 1996, September 20, 1996, September 30, 1996
and October 11, 1996, the SPC Board reviewed with SPC management a number of
additional factors relevant to the Merger, including the strategic overview and
prospects for SPC, its products and its finances. The SPC Board also considered,
among other matters (i) historical information concerning SPC's and Allegro's
respective businesses, prospects, financial performance and condition,
operations, technology, management and competitive position, including public
reports for each company filed with the SEC concerning results of operations
during the most recent fiscal year and fiscal quarter; (ii) SPC management's
view as to the financial condition, results of operations and businesses of
Allegro and SPC before and after giving effect to the Merger based on management
due diligence and publicly available financial information; (iii) current
financial market conditions and historical market prices, volatility and trading
information with respect to Allegro Common Stock and SPC Common Stock; (iv) the
consideration to be received by SPC stockholders in the Merger and the
relationship between the market value of the Allegro Common Stock to be issued
in exchange for each share of SPC Common Stock and a
 
                                       38
<PAGE>   47
 
comparison of comparable merger transactions; (v) the belief that the terms of
the Agreement, including the parties' representations, warranties and covenants,
and the conditions to their respective obligations, are reasonable; (vi) SPC
management's view as to the prospects of SPC as an independent company; (vii)
SPC management's view as to the potential for other third parties to enter into
strategic relationships with or to acquire Allegro or SPC; (viii) the impact of
the Merger on SPC's customers and employees; and (ix) reports from management
and financial advisors as to the results of their due diligence investigation of
Allegro. The SPC Board also considered the possible effects of the provisions
regarding the termination fees. In addition, the SPC Board noted that the Merger
is expected to be accounted for as a purchase and that currently the amount of
goodwill expected to be created on the books of the Combined Company cannot be
determined. At its October 11, 1996 meeting, the SPC Board considered financial
presentations by Unterberg Harris, including the financial analysis Unterberg
Harris delivered at this meeting of the SPC Board of Directors which concluded
that the Exchange Ratio provided in the Agreement was fair to SPC stockholders
from a financial point of view as of October 1, 1996 (a copy of this opinion is
annexed hereto, and stockholders are urged to carefully review this opinion).
The SPC Board also took into account that SPC would have representation on the
Board of the Combined Company following the Merger.
 
     The SPC Board also identified and considered a number of potentially
negative factors in its deliberations concerning the Merger, including, but not
limited to, (i) the risk that the potential benefits sought in the Merger might
not be fully realized, (ii) the possibility that the Merger would not be
consummated and the effect of the public announcement of the Merger on (a) SPC's
sales and operating results, (b) SPC's ability to attract and retain key
management, marketing and technical personnel and (c) the progress of certain
development projects, (iii) the potential dilutive effect of the issuance of
Allegro Common Stock in the Merger, (iv) the substantial charges to be incurred,
primarily in the quarter in which the Merger is consummated, in connection with
the Merger, including costs of integrating the businesses and transaction
expenses arising from the Merger, (v) the risk that despite the efforts of the
Combined Company, key technical and management personnel may not remain employed
by the Combined Company (vi) the difficulty of managing separate operations at
different geographic locations and (vii) the other risks described under "Risk
Factors" herein. The SPC Board believed that these risks were outweighed by the
potential benefits of the Merger.
 
MATERIAL CONTACTS AND BOARD DELIBERATIONS
 
     The market for business productivity and visual communications software has
become increasingly competitive over the last several years. In efforts to
enhance their market positions and grow their businesses in this difficult
environment, each of Allegro and SPC has continually evaluated various forms of
potential strategic relationships with other companies including OEM
arrangements, joint marketing relationships and acquisitions of technologies and
businesses.
 
     On August 13, 1996, SPC announced its third quarter 1996 results and a
strategic repositioning charge against earnings. SPC announced revenues of $2.2
million and a net loss of $4.3 million or $0.34 per share for its third fiscal
quarter ended June 30, 1996, compared to revenues of $4.4 million and a net loss
of $0.4 million or $0.03 per share for the third quarter of 1995. As a result,
SPC announced that it would reduce its worldwide headcount by approximately 42%
over the next two months and take a net charge to fourth quarter earnings of
between $2.0 and $3.0 million. SPC also announced that Irfan Salim, its
President and Chief Executive Officer, had resigned effective August 12.
 
     On August 27, 1996, Frost contacted SPC and requested an SPC Investor
Relations package. The requested information was subsequently mailed to Frost's
offices in San Francisco.
 
     On September 4, Ian Berman, Managing Director of Frost, called Miriam
Frazer, Vice President-Finance and Chief Financial Officer of SPC. He stated
that he had been keeping abreast of SPC's activities on behalf of his client,
Allegro, and that as a result of SPC's August 13th announcement he had been
instructed by his client to obtain the most current public information on SPC
and to arrange a meeting between the respective managements of Allegro and SPC
to explore a possible business relationship between the two companies.

     On September 5, Allegro and SPC entered into a mutual nondisclosure
agreement under which each agreed to maintain the confidentiality of the other
party's confidential information.
 
     In the morning of September 6, the SPC Board of Directors met by telephonic
conference and discussed various strategic alternatives for SPC.
 
     In the afternoon of September 6, Miriam Frazer, Daniel Fraisl, SPC's Vice
President-Research and Development, Joseph Szczepaniak, SPC's Vice
President-Sales and Marketing, jointly acting in their capacity as "The Office
of the President", had a lengthy telephone conference with Barry Cinnamon,
Allegro's Chief Executive Officer, Mark Leininger, Allegro's Vice
President-Finance and Chief Financial Officer, and Ian Berman. The
representatives of the two companies discussed the future objectives of the two
companies. The conversation included a preliminary discussion of the factors
supporting a possible business combination of the respective product lines,
technologies and market positions of SPC and Allegro, and the synergistic
factors associated with a possible strategic business combination of the two
companies. At the end of the call, each company concluded that it had interest
in pursuing additional discussions in person and a meeting was scheduled for the
following week at SPC's San Jose, California corporate headquarters.
 
     On September 9, a dinner meeting was held in San Jose with Miriam Frazer,
Daniel Fraisl and Joseph Szczepaniak of SPC, Barry Cinnamon and Mark Leininger
of Allegro and a representative of Frost attending to discuss further the
potential business strategies of a combined company and the key strengths of
each company.
 
     On September 10, at SPC's offices, business presentations were given by
each company to the other. In addition, Allegro discussed its recent acquisition
of Serif. A representative of Unterberg Harris joined the meeting. Preliminary
financial due diligence was conducted by both companies and continued into the
next day.
 
     On September 11, SPC, Allegro and their respective financial advisors
continued discussions, due diligence and negotiation of the broad terms of a
merger between the two companies.
 
     On September 12, Miriam Frazer, Daniel Fraisl, and Joseph Szczepaniak met
with Fred Gibbons, Chairman of SPC, and Bernee Strom, a director of SPC, to
inform them of the status of discussions between the two companies. These
directors requested SPC management explore further the possibility of combining
SPC and Allegro.
 
     On September 13, the SPC Board of Directors met by telephonic conference,
during which SPC management reviewed with the Board the status of discussions
between the two companies concerning a possible strategic business combination.
There was a preliminary discussion of the factors supporting a possible
combination of the respective product lines, technologies and market positions
of SPC and Allegro, and of the synergistic factors associated with a possible
strategic business combination of SPC and Allegro. The SPC Board authorized SPC
management to continue the discussions with Allegro regarding a possible
combination.
 
     Between September 13 and September 18, there were a series of telephone
conversations between representatives of SPC and Allegro involving discussions
of the business operations and technology of each company and of a combined
company that would result from a "merger of equals" business combination.
 
     On September 18, Bernee Strom and Barry Cinnamon met for dinner in
Washington, D.C. to discuss the status of discussions between SPC and Allegro,
the feasibility of a business combination, and the broad structure of a
potential transaction.
 
     On September 19, representatives of SPC, Allegro and their respective
financial advisors met to discuss a potential combined company product strategy,
operating structure and pro forma statement of operations and balance sheet,
including estimates of potential one-time charges and associated savings
generated from the economies of scale of a combined company. Later that day,
Fred Gibbons and Barry Cinnamon met for dinner in San Jose, California to
discuss the proposed combination of the two companies.

     On September 20, the SPC Board of Directors met in Palo Alto, California.
With all outside directors in attendance, the Board first met with SPC's legal
and financial advisors to be briefed regarding SPC management's discussions with
Allegro and Allegro's advisors. SPC's management director and the other members
of SPC management then joined the meeting and discussed (i) the status of
discussions with Allegro, the results of their due diligence evaluation of
Allegro, and the potential benefits and risks of a business combination with
Allegro, including Allegro's recent acquisition of Serif and Allegro's financial
results to date for the second quarter of fiscal year 1996, and (ii) the
principal terms of a potential business combination. In addition, there was a

and the potential impact of the proposed exchange ratio based on the
then-current trading prices for the Allegro Common Stock and the SPC Common
Stock. SPC's legal counsel discussed the Board's fiduciary duties in considering
a strategic business combination and strategic alternatives, and held further
discussions with the Board on principal terms of a potential agreement. SPC's
financial advisor then reviewed, among other things, the strategic rationale
for, and certain financial analyses relating to the proposed merger. Management
and representatives of Allegro then joined the meeting to make a joint
presentation, together with SPC's management, regarding the proposed combined
company and addressed questions and comments of the Board. At the conclusion of
the meeting, the SPC Board of Directors unanimously agreed that management
should continue to proceed with the negotiation and investigation of the
proposed combination.

     On September 26, the Allegro Board of Directors met at Allegro's offices in
Fairfield, New Jersey. With all directors in attendance, the Board met with
Allegro's management and legal and financial advisors to be briefed regarding
Allegro management's discussions with SPC and SPC's advisors. The Board

combination with SPC, taking into account Allegro's recent acquisition of Serif
and SPC's financial results to date for the third quarter of fiscal year 1996,
and (ii) the principal terms of a potential business combination. In addition,
there was a discussion regarding the potential market reaction to the proposed
combination and the potential impact of the proposed exchange ratio based on the
then-current trading prices for the Allegro Common Stock and the SPC Common
Stock. Allegro's legal counsel discussed the Board's fiduciary duties in
considering a strategic business combination and strategic alternatives, and
held further discussions with the Board on principal terms of a potential
agreement. Allegro's financial advisor then reviewed, among other things, the
strategic rationale for, and certain financial analyses relating to, the
proposed merger. SPC's management team joined the meeting and made a
comprehensive presentation to the Allegro Board of Directors, which included
sales and marketing objectives and positioning, product demonstrations and
future product plans, and financial forecasts. At the conclusion of the meeting,
the Allegro Board of Directors unanimously approved such combination in
principle, subject to the receipt of a fairness opinion, and directed Allegro
management to continue to proceed with the negotiation and investigation of the
proposed combination.
 
     On September 27, SPC management returned to San Jose, California to prepare
with their advisors for the negotiation of a definitive agreement related to the

of the proposed exchange ratio, accounting treatment, the composition of the
Board of Directors of the proposed combined company, the termination rights of
the parties under the agreement, the conditions upon which any break up fees
would be payable and the amount of such fees, and the representations and
warranties and covenants to be made. Additional due diligence by SPC of Allegro
and by Allegro of SPC also took place during these meetings.

of up to $1.0 million to Allegro pursuant to the terms of the proposed
Agreement. At the September 30, 1996 meeting, the SPC Board confirmed that the
transactions contemplated by the Merger Agreement and the consummation of the
Merger would not result in Allegro becoming an Acquiring Person within the

the Allegro Board's fiduciary duties in considering a strategic business
combination and reviewed proposed terms of the definitive agreements related to
the transaction, and (v) Ian Berman of Frost again discussed the exchange ratio,
reviewed financial analyses and financial information with respect to both
companies and orally informed the Board that Frost believed that the Merger was
fair to Allegro and its stockholders. The Allegro Board of Directors approved
the transaction subject to receiving a satisfactory written fairness opinion
from Frost on or before Friday, October 11, 1996.
 
     Late in the evening of October 1, representatives of SPC and Allegro
reached agreement on all remaining issues, and the Agreement and Plan of
Reorganization and related agreements were executed by the respective parties
thereto. Prior to the opening of the market on October 2, a joint press release
was issued by SPC and Allegro announcing the Merger.
 
     On October 11, 1996, the SPC Board of Directors met by telephone
conference. At the meeting representatives of Unterberg Harris reviewed and
analyzed the exchange ratio, the financial performance of SPC and Allegro, the
pro forma financial performance of the Combined Company, and comparable industry
information. Unterberg Harris and SPC management responded to questions from the
Board, and Unterberg Harris delivered its written opinion to the effect that the
consideration to be received by the SPC stockholders pursuant to the Agreement
was fair from a financial point of view as of September 30, 1996. On October 11,
1996, Frost delivered to the Allegro Board its written opinion, dated September
30, 1996, to the effect that the Exchange Ratio was fair to Allegro and its
stockholders from a financial point of view.
 
     On October 23, 1996, the SPC Board of Directors met in person. At this
meeting the SPC Board reviewed SPC's fiscal year 1996 operating and financial
results and reviewed the status of the completion of the Allegro transaction. In
addition, the SPC Board awarded a bonus of $25,000 to each of Miriam K. Frazer,
Daniel J. Fraisl and Joseph Szczepaniak, payable following the first profitable
fiscal quarter of the Combined Company. The SPC Board also awarded to each of
Dr. Gilbert, Ms. Strom and Mr. Bertelsen, outside directors of SPC, options to
purchase 30,000 shares of SPC Common Stock at an exercise price of $1.25 (the
fair market value thereof on the date of grant), which options are exercisable
in three equal installments, on the date of grant and on the first and second
anniversaries of the date of grant.
 
     On October 25, the Allegro Board of Directors met by telephone conference.
At the meeting, representatives of Frost made a presentation to the Board
regarding the various analyses underlying its conclusion regarding the fairness
of the Merger, as contained and set forth in the Frost Opinion (as defined
below), and responded to questions from the members of the Board. In addition,
the Allegro Board decided to

increase Barry A. Cinnamon's salary to $150,000 per year and to increase Mark E.
Leininger's salary to $145,000 per year, in each case effective at the Effective
Time, as well as to pay a bonus of $25,000 to each of Mr. Cinnamon and Mr.

OPINION OF ALLEGRO'S FINANCIAL ADVISOR
 
     Allegro retained Frost Capital Partners, Inc. ("Frost") on August 27, 1996,
to provide certain investment banking advice and services in connection with the
Merger and on September 23, 1996, to deliver a financial opinion letter (the
"Frost Opinion") in connection with the Merger. Frost was selected by Allegro's
Board to provide the Frost Opinion based on Frost's qualifications, expertise
and reputation in the computer software industry, as well as Frost's investment
banking relationship and familiarity with Allegro. Frost is a well recognized
investment banking and advisory firm that specializes in the computer software
industry. Frost, as part of its investment banking business, is continuously
engaged in the valuation of businesses and securities in connection with mergers
and acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes.
 
     At the meetings of the Allegro Board on September 26 and 30, 1996, Frost
rendered its oral opinion, subsequently confirmed in writing, that as of such
dates, based upon the facts and circumstances as they existed at such dates and
subject to the various assumptions, factors, and limitations set forth in the
Frost Opinion, the Exchange Ratio was fair from a financial point of view to
Allegro and its stockholders. At the meeting of the Allegro Board on October 25,
1996, Frost reviewed in detail with the Allegro Board the various types of
analyses it utilized in rendering the Frost Opinion.
 
     THE FULL TEXT OF THE WRITTEN FROST OPINION, DATED SEPTEMBER 30, 1996, WHICH
SETS FORTH, AMONG OTHER THINGS, ASSUMPTIONS MADE, MATTERS CONSIDERED, AND

FROST OPINION, IS ATTACHED AS ANNEX B TO THIS PROSPECTUS/JOINT PROXY STATEMENT.
ALLEGRO STOCKHOLDERS ARE URGED TO READ THE FROST OPINION CAREFULLY AND IN ITS
ENTIRETY. FROST DID NOT RECOMMEND TO ALLEGRO THAT ANY SPECIFIC EXCHANGE RATIO

DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER OF ALLEGRO AS TO HOW
SUCH STOCKHOLDER SHOULD VOTE AT THE ALLEGRO MEETING. THE SUMMARY OF THE FROST
OPINION SET FORTH IN THIS PROSPECTUS/JOINT PROXY STATEMENT IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.

appropriate.
 
     In rendering its opinion, Frost assumed and relied upon, without
independent verification, the accuracy and completeness of the information
reviewed by it for the purposes of the Frost Opinion. With respect to the
financial projections of Allegro and SPC, including estimates of potential
synergies for the Combined Company, and other information relating to the
prospects of Allegro and SPC provided to Frost by each company, Frost assumed
that such projections and other information were reasonably prepared and
reflected the currently available judgments and estimates of the respective
management of Allegro and SPC as to the likely future financial performances of
their respective companies and of the combined entity. The financial projections
of Allegro and SPC that were provided to Frost were utilized and relied upon by
Frost in both the Contribution Analysis and the Pro Forma Earnings Analysis
summarized below. In addition, Frost did not make and it was not provided with
an independent evaluation or appraisal of the assets of Allegro or SPC, nor did
it make any physical inspection of the properties or assets of Allegro or SPC.
The Frost Opinion states that it is necessarily based on economic, market and
other conditions in effect on, and the information made available to Frost as
of, the date of the Frost Opinion.
 
     The following is a summary of the analysis performed by Frost in
preparation of the Frost Opinion and reviewed with the Board of Directors of
Allegro at meetings held on September 26, 1996, September 30, 1996 and October
25, 1996.
 
  Historical Stock Price Performance
 
     Frost reviewed the per share market prices and trading volume for the
Allegro Common Stock, from December 7, 1995, the date of Allegro's initial
public offering (the "Allegro IPO"), to October 1, 1996 and for SPC Common Stock
for the same period. Frost also reviewed the daily closing per share market
prices of the Allegro Common Stock and SPC Common Stock and compared the
movement of such daily closing prices with the movement of the Nasdaq composite
average over the periods from December 7, 1995 through October 1, 1996. Frost
noted that, on a relative basis, both Allegro and SPC underperformed the Nasdaq
composite average during the period from December 7, 1995 to October 1, 1996,
and that Allegro significantly outperformed SPC during the same period. However,
while SPC Common Stock also underperformed relative to the Nasdaq composite for
the six-month period ending October 1, 1996, Allegro significantly outperformed
the composite with a six-month return of 106.9% relative to the Nasdaq composite
gain of 10.39% over the same period. Frost also reviewed the daily closing per
share market prices of the Allegro Common Stock and SPC Common Stock and
compared the movement of such daily closing prices with the movement of a
composite index over the periods from December 7, 1995 through October 1, 1996
comprised of the following companies: Adobe Systems Inc., Autodesk Inc., Corel
Corp., Hyperion Software Corp., International Microcomputer Software Inc.,
Interleaf Inc., Macromedia, Inc., Micrografx, Inc., MySoftware Company, and
Visio Corp. (collectively, the "Selected Companies"). While the composite index
has been consistently sluggish, generating a -19.4% return over the six month
period ending October 1, 1996 and -31.4% over the December 7, 1995 to October 1,
1996 time period, Allegro has generated gains of 106.9% and 0.0%,
 
                                       44
<PAGE>   53
 
respectively over the same periods. SPC's stock generated returns of -41.7% and
- -50.0%, respectively over these same periods.
 
  Historical Exchange Ratio Analysis
 
     Frost reviewed and analyzed the historical ratio of the daily per-share
market closing prices of SPC Common Stock divided by the corresponding prices of
the Allegro Common Stock since the Allegro IPO on December 7, 1995, as well as
for the six-month, three-month and one-month periods prior to October 1, 1996
and as of October 1, 1996 (the last business day prior to the announcement of
the October 1, 1996 signing of the Agreement and prior to any transaction
premium being reflected in the SPC market price). Such average exchange ratios
for the aforementioned time periods and as of such date were .4569, .4010,
 .3042, .2054 and .2333, respectively. Frost then calculated the respective
premiums and/or discounts above or below such average daily exchange ratios
represented by the Exchange Ratio, which for the same time periods and as of
such date were -41.34%, -33.15%, -11.88%, 30.49% and 14.88%, respectively. Frost
noted that the movement of the premiums and/or discounts above or below the
average daily exchange ratios, for the periods prior to October 1, 1996 and as
of October 1, 1996, represented by the Exchange Ratio for the same periods,
reflected that the price of the Allegro Common Stock generally outperformed that
of SPC Common Stock over these periods. In addition, Frost derived the 30-day,
90-day and 180-day moving 30-day average exchange ratios over the ten-month
period from January 18, 1996 (thirty business days after the Allegro IPO) to
October 1, 1996, which for these time periods were .2344, .3630, and .4617,
respectively. Frost then calculated the respective premiums over such average
moving exchange ratios represented by the Exchange Ratio, which for these time
periods were 14.4%, -26.2% and -41.9%, respectively. Frost concluded that
average exchange ratios derived for the 30-day, 90-day and 180-day moving 30 day
average were not materially different from the exchange ratios calculated over
the one-month, three-month and six-month periods prior to October 1, 1996.
 
     Frost reviewed the following five software transactions since 1994: the
mergers of Delrina Corp. with Symantec Corp., Frame Technology with Adobe
Systems, Inc., PowerSoft Corp. with Sybase, Inc., Intuit, Inc. with Microsoft
Corp., and Aldus Corp. with Adobe Systems, Inc. These transactions were chosen
because each transaction involved the acquisition of a software company with
similar products to that of SPC, in which the consideration was paid in the form
of stock. The analysis showed transaction exchange ratios resulting, on average,
in a premium of approximately 39.0% over the observed exchange ratios for the
period of one month preceding the day of the public announcement of these
transactions. Frost also reviewed the average premium extending back to 207
trading days prior to that day (the number of trading days between the Allegro
IPO and the day before the public announcement of the acquisition of SPC). Frost
observed that for the one month period prior to the announcement, the premium
over the Exchange Ratio was 30.5%, which is below the 39.0% for the comparable
transactions. For the 207-day period, the Exchange Ratio represented an average
discount of -8.2% below the average ratio of SPC to Allegro stock prices for
comparable periods as of October 1, 1996. Frost concluded that the premium paid,
represented by the Exchange Ratio, appears reasonable.
 
  Analysis of Comparable Public Companies
 
     Frost compared certain financial information relating to Allegro and SPC to
certain corresponding information from a group of ten publicly-traded PC
business and/or personal productivity software companies consisting of the
Selected Companies. The Selected Companies were chosen because they are engaged
in the development of PC business and/or personal productivity software,
specifically in the fields of business graphics or desktop publishing. Because
these comparable companies are typically influenced by the same economic or
business trends, the market is presumed to hold similar expectations for Allegro
and SPC as it would for these industry participants. Such financial information
included, among other things, market valuation, ratios of market value to each
of revenues, total assets, net worth, net income and earnings, and ratios of
stock price to earnings per share. Frost concluded that due to the fact that
each of Allegro and SPC had negative earnings, analyses of trading multiples
based on revenues, total assets and net worth would be more applicable than
earnings related multiples. Such analyses showed that as of September 30, 1996,
using trading multiples applied to the total invested capital (a company's
market value, calculated by multiplying
 
                                       45
<PAGE>   54
 
the number of shares outstanding by its stock price, plus all of the company's
outstanding debt), Allegro and SPC had multiples of revenues of 1.76 and 1.76
for fiscal year 1997 forecasted earnings, respectively, and 2.92 and 1.26 for
the twelve months ended June 30, 1996 respectively, compared to a low of .45, a
high of 7.57, a mean of 2.71 and a median of 1.79 for fiscal year forecasted
earnings and a low of .53, a high of 11.46, a mean of 3.01 and a median of 1.71
for the latest twelve months for the Selected Companies. Allegro and SPC had
multiples of total assets of 6.58 and .87 for the twelve months ended June 30,
1996, respectively, compared to a low of .97, a high of 9.33, a mean of 2.85 and
a median of 1.87 for the latest twelve months for the Selected Companies. In
addition, such analyses showed that Allegro and SPC had multiples of net worth
of 13.27 and 1.88 for the twelve months ended June 30, 1996, respectively,
compared to a low of 1.71, a high of 12.04, a mean of 4.29 and a median of 3.23
for the latest twelve months for the Selected Companies.
 
  Analysis of Selected Precedent Market Transactions.
 
     Frost analyzed and reviewed pending and completed mergers and acquisitions,
from January 1994 to September 1996, in the following areas: business and/or
personal productivity software transactions and other software company pooling
and purchase transactions (collectively, "Selected Transactions"). Frost
identified 20 transactions for analyzing SPC and 17 for analyzing Allegro. Frost
calculated various financial multiples, based on certain publicly available
information and estimates, for each of the Selected Transactions, and compared
them to corresponding financial multiples for the Merger, based on the Exchange
Ratio of 0.26805 shares of Allegro Common Stock for each share of SPC Common
Stock.
 
     SPC Comparables.  Fourteen of the comparable transactions identified
involved the pooling or purchase of a privately held business and/or personal
productivity software company. They included: (1) Reality Technologies by
Reuters (1/94); (2) Central Point Software by Symantec Corp. (3/94); (3) T/Maker
by Deluxe (6/94); (4) Parsons by Intuit (8/94); (5)Arabesque Software by
NetManage Inc. (9/94); (6) Pillar Corp. by Hyperion (11/94); (7) Altsys Corp. by
Macromedia (1/95); (8) Collabra Software by Netscape (9/95); (9) Renaissance
Software by SunGuard Data Systems (9/95); (10) Swfte by Expert (10/95); (11)
TriMetrix Software by MathSoft (11/95); (12) Visual Software by Micrografx
(2/96); (13) T/Maker by Broderbund (7/96); and (14) CLEAR Software by SPSS Inc.
(9/96). Frost also analyzed six other software company transactions where the
target was a publicly held business and/or personal productivity software
company ("Selected Public Company Transactions"): (1) Aldus by Adobe Systems
(3/94); (2) Intuit by Microsoft (10/94, aborted); (3) Powersoft by Sybase
(11/94); (4) Lotus Development by IBM (6/95); (5) Frame Technology Corp. by
Adobe Systems (6/95); and (6) Delrina by Symantec (7/95). All of these
transactions involved the issuance of stock and/or cash, and were accounted for
as a pooling of interests or purchase.
 
     SPC's market multiples for Net Income, EBIT, and EBITDA (earnings before
interest, taxes, depreciation and amortization) were not used in this analysis
(results of the calculations were not meaningful), since the company incurred
losses for the twelve months ending June 30, 1996 and fiscal year ending
September 30, 1996 (based on preliminary reports). Frost noted that the
multiples of adjusted purchase price (purchase price adjusted for debt and cash)
to trailing twelve month revenues ranged from 1.00 to 9.36, with a mean of 3.35
for the Selected Transactions (Public & Private, excluding Collabra) and 1.72 to
7.20, with a mean of 4.64 for the Selected Public Company Transactions. The
multiple of adjusted purchase price to trailing twelve month revenues calculated
for SPC was 0.70, which falls below the range and mean derived for the Selected
Transactions and Selected Public Company Transactions.
 
     Allegro Comparables.  Fourteen of the comparable transactions identified
involved the pooling or purchase of a privately held business and/or personal
productivity software company. They included: (1) Central Point Software by
Symantec Corp. (3/94); (2) T/Maker by Deluxe (6/94); (3) Parsons by Intuit
(8/94); (4) Pillar Corp. by Hyperion (11/94); (5) Altsys Corp. by Macromedia
(1/95); (6) The Pixellite Group by Sierra On-Line (5/95); (7) Tewi Verlag by
SoftKey International (7/95); (8) MicroLogic Software by Mindscape Inc. (9/95);
(9) Renaissance Software by SunGuard Data Systems (9/95); (10) Swfte by Expert
(10/95); (11) TriMetrix Software by MathSoft (11/95); (12) T/Maker by Broderbund
(7/96); (13) Serif Inc. and Serif (Europe) Ltd. by Allegro New Media (8/96); and
(14) CLEAR Software by SPSS Inc. (9/96). Frost also analyzed three other
software company transactions
 
                                       46
<PAGE>   55
 
where the target was a publicly held business and/or personal productivity
software company ("Selected Public Company Transactions") including: (1) Aldus
by Adobe Systems (3/94); (2) Intuit by Microsoft (10/94, aborted); and (3)
Delrina by Symantec (7/95). All of these transactions involved the issuance of
stock and/or cash, and were accounted for as a pooling of interests or purchase.
Frost noted that the multiples of adjusted valuation to trailing twelve month
revenues ranged from 0.33 to 9.36, with a mean of 2.68 for the Selected
Transactions (Public & Private), and 1.72 to 5.97, with a mean of 3.84 for the
Selected Public Company Transactions. The multiple of adjusted valuation to
trailing twelve month revenues calculated for Allegro was 2.71, which falls
within the range calculated for the Selected Transactions and Selected Public
Company Transactions.
 
  Contribution Analysis
 
     Frost analyzed the relative contributions of Allegro and SPC to the pro
forma income statement of the Combined Company, based on Allegro management's
projections for the respective companies. Frost excluded amortization and other
non-recurring expenses relating to the Merger from this analysis. This analysis
showed that on a pro forma combined basis, based on the twelve-month period
ending December 1997 for Allegro and the twelve-month period ending December
1997 for SPC, Allegro and SPC would account for approximately 53.7% and 46.3%,
respectively, of the Combined Company's pro forma revenue and approximately 6.8%
and 93.2%, respectively, of the Combined Company's pro forma net income. Frost
also reviewed certain information provided by Allegro and SPC management which
identified cost savings and efficiencies projected to be gained through the
combination of the two entities. The analysis indicated, absent potential
synergies, both SPC and Allegro would generate significant operating losses for
the year ending December 31, 1997; however, when considering potential operating
efficiencies of the Combined Company, the Merger provided significant
improvement in operating performance.
 
  Pro Forma Analysis of the Merger
 
     Frost analyzed certain pro forma effects of the Merger on management's
projections of the earnings of the Combined Company. Based on such analysis,
Frost computed the resulting dilution/accretion to Allegro's earnings per share
estimate for the fiscal year ending December 31, 1997, pursuant to the Merger
and after taking into account any potential cost savings and other synergies
that Allegro might be able to achieve if the Merger were consummated and before
certain non-recurring costs. Frost concluded that the Merger would have a
significant positive impact, assuming cost savings and certain operating
synergies, on the earnings per share for Allegro stockholders.
 
     In connection with the review of the Merger by the Allegro Board, Frost
performed a variety of financial and comparative analyses for purposes of the
Frost Opinion given in connection therewith. While the foregoing summary
describes all material analyses and factors reviewed by Frost with the Allegro
Board it does not purport to be a complete description of the presentations by
Frost to the Allegro Board or the analyses performed by Frost in arriving at the
Frost Opinion. The preparation of a fairness opinion is a complex process and is
not necessarily susceptible to partial analysis or summary description. Frost
believes that its analyses must be considered as a whole and that selecting
portions of its analyses and of the factors considered by it, without
considering all analyses and factors, could create a misleading view of the
processes underlying the Frost Opinion. In addition, Frost may have given
various analyses more or less weight than other analyses, and may have deemed
various assumptions more or less probable than other assumptions, so that the
range of valuation resulting from any particular analysis described above should
not be taken to be Frost's view of the actual value of Allegro or SPC. In
performing its analyses, Frost made numerous assumptions with respect to
industry performance, general business and economic conditions and other
matters, many of which are beyond the control of Allegro or SPC. The analyses
performed by Frost are not necessarily indicative of actual values or actual
future results, which may be significantly more or less favorable than suggested
by such analyses. In addition, analyses relating to the value of businesses or
assets do not purport to be appraisals or to necessarily reflect the prices at
which businesses or assets may actually be sold. The analyses performed were
prepared solely as part of Frost's analysis of the fairness of the Exchange
Ratio, from a financial point of view, to
 
                                       47
<PAGE>   56
 
Allegro and its stockholders and were provided to the Allegro Board in
connection with the delivery of the Frost Opinion.
 
     In the ordinary course of Frost's trading and brokerage activities, Frost
or its affiliates may at any time hold long or short positions, may trade or
otherwise effect transactions, for its own account or for the account of
customers, in debt or equity securities of Allegro or SPC. As of October 28,
1996, Frost owns 14,181 shares and options to purchase 25,000 shares of Allegro
Common Stock which it received as payment for a previous transaction with
Allegro in which Frost acted as financial advisor. Frost has no proprietary
holdings in SPC.
 
     Pursuant to a letter agreement dated August 27, 1996, Allegro agreed to pay
Frost a monthly advisory fee of $10,000 to assist Allegro in analyzing potential
merger/acquisition targets, including SPC. If the Merger is consummated, Allegro
has agreed to pay Frost a fee (the "Financial Advisory Fee") equal to
approximately 2.3% of the value of the consideration paid for SPC's common
equity for acting as its financial advisor in connection with the Merger. Fifty
percent of such fees will be paid in the form of Allegro stock. Allegro has also
agreed to pay Frost $100,000 for rendering the Frost Opinion. Furthermore,
Allegro has also agreed to reimburse Frost for its reasonable out-of-pocket
expenses incurred in connection with rendering financial advisory services,
including fees and disbursements of its legal counsel. Allegro has agreed to
indemnify Frost and its directors, officers, agents, employees and controlling
persons, for certain costs, expenses, losses, claims, damages and liabilities
related to or arising out of its rendering of services under its engagement as
financial advisor.
 
OPINION OF SPC'S FINANCIAL ADVISOR
 
     Unterberg Harris has delivered to the SPC Board of Directors a written
opinion dated October 11, 1996 to the effect that, as of October 1, 1996, the
consideration to be received by holders of shares of SPC Common Stock pursuant
to the Agreement was fair, from a financial point of view, to such holders. No
limitations were imposed by the SPC Board upon Unterberg Harris with respect to
the investigations made or the procedures followed by it in rendering its
opinion.
 
     THE FULL TEXT OF THE OPINION OF UNTERBERG HARRIS IS ATTACHED HERETO AS
ANNEX C. SPC STOCKHOLDERS ARE URGED TO READ THE OPINION IN ITS ENTIRETY FOR THE
ASSUMPTIONS MADE, PROCEDURES FOLLOWED, OTHER MATTERS CONSIDERED AND LIMITS OF
THE REVIEW BY UNTERBERG HARRIS. THE SUMMARY OF THE OPINION OF UNTERBERG HARRIS
SET FORTH IN THIS PROSPECTUS/JOINT PROXY STATEMENT IS QUALIFIED IN ITS ENTIRETY
BY REFERENCES TO THE FULL TEXT OF SUCH OPINION. UNTERBERG HARRIS' OPINION WAS
PREPARED FOR THE SPC BOARD OF DIRECTORS AND IS DIRECTED ONLY TO THE FAIRNESS,
FROM A FINANCIAL POINT OF VIEW, OF THE CONSIDERATION TO BE RECEIVED BY HOLDERS
OF SHARES OF SPC COMMON STOCK PURSUANT TO THE AGREEMENT AND DOES NOT
CONSTITUTIVE A RECOMMENDATION TO ANY SPC STOCKHOLDER AS TO HOW TO VOTE AT THE
SPC MEETING.
 
     In arriving at its opinion, Unterberg Harris reviewed the Agreement and
certain financial and other information that was publicly available or furnished
to Unterberg Harris by SPC and Allegro, including financial forecasts and other
information provided during discussions with the managements of SPC and Allegro.
In addition, Unterberg Harris compared certain financial and securities data of
SPC and Allegro with those of various other publicly traded companies in the
software industry, reviewed the historical stock prices and trading volumes of
SPC Common Stock and Allegro Common Stock, reviewed prices and premiums, if any,
paid in other similar business combinations and conducted such other financial
studies, analyses and investigations as Unterberg Harris deemed appropriate for
purposes of rendering its opinion.
 
     In rendering its opinion, Unterberg Harris assumed, without independent
verification, the accuracy, completeness and fairness of all financial and other
information available to it from public sources or provided to it by SPC and
Allegro. With respect to the financial projections supplied to it, Unterberg
Harris assumed that such projections were reasonably prepared and that they
reflected the most accurate currently available estimates and judgments of the
managements of SPC and Allegro as to the future operating and financial
performances of their respective companies. Unterberg Harris did not make any
independent evaluation or appraisal of the assets, liabilities, patents or
intellectual property of SPC or Allegro, nor was any such appraisal or
evaluation provided to Unterberg Harris. Unterberg Harris assumed that the
Merger would be accounted for as a purchase in rendering its opinion.

     Unterberg Harris' opinion is necessarily based on economic, market,
financial and other conditions as they existed on, and on the information made
available to it as of October 1, 1996. Unterberg Harris does not have any
obligation to confirm or update its opinion at any subsequent time.
 
     The following presentation summarizes certain financial analyses performed
by Unterberg Harris in arriving at its opinion, which analyses Unterberg Harris
discussed with the SPC Board of Directors.
 
     Comparable Companies Analyses.  Unterberg Harris compared selected
historical and projected operating information, stock market data and financial
ratios for SPC (based on the value of the SPC Common Stock implied by the
financial terms of the Merger) to selected historical and projected operating
information, stock market data and financial ratios of Allegro and of certain
other publicly traded software companies. These companies included Adobe Systems
Inc., Caere Corporation, Corel Corporation, DeltaPoint, Inc., Fractal Design
Corporation, International Microcomputer Software Inc., Macromedia, Inc.,
MetaTools, Inc., Micrografx, Inc., MySoftware Company, Quarterdeck Corporation,
Softkey International Inc., Symantec Corporation, and Visio Corporation. Such
data and ratios include multiples of net market value (defined as market value
of equity as of October 1, 1996 adjusted by adding long-term debt and
subtracting cash and short-term investments) to historical revenues, market
value to historical and projected net income and earnings per share, and market
value to book value. The market value for SPC is based on the Exchange Ratio and
closing price of the Allegro Common Stock as of October 1, 1996.
 
     An analysis of the ratio of net market value to latest twelve month
revenues for each of the comparable companies yielded a range of 0.6 times to
11.5 times revenues with a median of 2.8 times revenues. This compared to a
multiple of 1.0 times revenues for SPC, as implied by the value to be received
for the SPC Common Stock in this transaction, and 3.4 times for Allegro.
 
     An analysis of the ratio of current stock price to their latest twelve
month earnings per share for each of the comparable companies yielded a range of
not meaningful (due to earnings losses or extreme divergences in stock price and
earnings per share) to 77.6 times earnings, with a median of 25.6 times earnings
(excluding any not meaningful ratios). This ratio was not meaningful ratio for
either SPC or Allegro due to each company's earnings loss for the period.
 
     An analysis of the ratio of current stock price to projected calendar 1996
earning per share for each of the comparable companies yielded a range of not
meaningful (due to earnings losses) to 60.3 times earnings, with a median of
19.0 times earnings (excluding not meaningful ratios). This ratio was not
meaningful for either SPC or Allegro due to each company's earnings loss
projected for the period.
 
     An analysis of the ratio of current stock price to projected calendar 1997
earning per share for each of the comparable companies yielded a range of 8.7
times to 41.3 times earnings, with a median of 16.0 times earnings. This ratio
was not meaningful for either SPC or Allegro due to each company's earnings loss
projected for the period.
 
     An analysis of the ratio of market value to book value for each of the
comparable companies yielded a range of 1.8 times to 15.3 times book value, with
a median of 4.3 times book value. This compared to a multiple of 3.5 times book
value for SPC, as implied by the value to be received for the SPC Common Stock
in this transaction, and 9.3 times book value for Allegro.
 
     Based upon the foregoing, Unterberg Harris indicated that the multiples
calculated for SPC, as implied by the financial terms of the Merger, were within
the range of multiples for the comparable companies analyzed and below the
median for multiples of revenue and book value. The comparison to multiples of
earnings per share were not meaningful. Unterberg Harris also indicated that the
multiples calculated for Allegro were within the range of multiples for
comparable companies, except with respect to multiples of earnings per share,
which were not meaningful.
 
     Comparable Transaction Analysis.  Unterberg Harris reviewed certain mergers
and acquisitions involving software-related companies. In examining these
transactions, Unterberg Harris analyzed certain income statement and balance
sheet parameters of the acquired companies relative to the consideration paid.
Multiples analyzed included net transaction value (defined as transaction value
adjusted by adding long-term
 
                                       49
<PAGE>   58
 
debt and subtracting cash and short-term investments) to the latest twelve month
revenues and transaction value to the latest twelve months net income and book
value. This analysis included 62 comparable software company transactions that
occurred from February 1993 through September 1996 or were pending during such
period. In certain cases, complete financial data was not publicly available for
these transactions, and only partial information was used in such instances. The
transaction value of the present Merger is based on the Exchange Ratio and
closing price of Allegro Common Stock as of October 1, 1996.
 
     An analysis of the ratio of net transaction value to latest twelve month
revenues for each of the comparable transactions yielded a range of 0.3 times to
22.9 times revenues, with a median of 2.9 times revenues. The multiple for the
present Merger was 1.0 times SPC revenues.
 
     An analysis of the ratio of transaction value to the latest twelve month
net income for each of the comparable transactions yielded a range of not
meaningful (due to earnings losses) to 346.5 times net income, with a median of
41.7 times (excluding not meaningful ratios). This multiple was not meaningful
for the present Merger due to SPC's earnings loss in the period.
 
     An analysis of the ratio of transaction value to book value for each of the
comparable transactions yielded a range of not meaningful (due to negative
values) to 38.0 times book value, with a median of 5.7 times book value. The
multiple for the present Merger was 3.5 times SPC book value.
 
     Based upon the foregoing, Unterberg Harris indicated that the multiples
calculated for SPC based on the financial terms of the Merger were within the
range for multiples of comparable transactions analyzed. Unterberg Harris also
indicated that the purchase price paid to SPC stockholders in the Merger
reflected a premium over the median earnings multiple paid in the comparable
merger and acquisition transactions analyzed because SPC had an earnings loss
for the latest twelve month period and projected an earnings loss for the
calendar year ended December 31, 1996.
 
     Acquisition Premium Analysis.  Unterberg Harris also reviewed the premiums
paid for certain merger and acquisition transactions involving selected software
companies. Unterberg Harris' analysis indicated that the percentage premium of
offer prices to trading prices on the day prior to the announcement date ranged
from a 3.3% discount to 96.9% premium, with a median of 23.6%. The percentage
premium of offer prices to trading prices thirty days prior to the announcement
date ranged from 9.3% to 103.2%, with a median of 44.2%. The offer price for SPC
based on the Exchange Ratio and closing price of Allegro Common Stock as of
October 1, 1996 was 14.9% above SPC's closing stock price on the day prior to
the date of announcement, and 34.0% above SPC's closing stock price thirty days
prior to the date of announcement.
 
     As part of its analysis, Unterberg Harris also indicated that the
transaction value represented a 23.7% premium over the closing stock price of
SPC Common Stock one week prior to the date of announcement, a 34.0% premium
over the closing stock price ten trading days prior to the date of announcement,
a 60.8% premium over the closing stock price twenty trading days prior to the
date of announcement, a 34.0% premium over the closing stock price thirty
trading days prior to the date of announcement, and a 30.1% discount over the
closing stock price sixty trading days prior to the date of announcement. The
transaction value also represented a 17.6% premium over the average of the
closing prices of the SPC Common Stock over the ten days prior to the date of
announcement, a 25.6% premium over such average over the twenty days prior to
the date of announcement, a 30.5% premium over the such average over the thirty
days prior to the date of announcement, and a 3.3% discount to such average over
the sixty days prior to the date of announcement.
 
     Discounted Cash Flow Analysis.  Unterberg Harris estimated present values
of SPC using a discounted cash flow analysis based on SPC management's
estimates. Unterberg Harris calculated present values of projected SPC operating
cash flows over the period between September 30, 1996 and September 30, 2001
using discount rates between 15% and 35%. Unterberg Harris also calculated
approximate terminal values for SPC as of September 30, 2001, which were then
discounted to present value using the same discount rates as the cash flows.
Unterberg Harris then calculated an implied valuation of SPC by adding the
present value of the cash flows to the present value of the terminal value. The
implied values of SPC based on this analysis ranged from $2.1 million to $12.4
million. Unterberg Harris therefore determined that, as of the date of the
Agreement, the value of the consideration to be received by SPC stockholders in
the Merger was greater than
 
                                       50
<PAGE>   59
 
the range of present values of SPC's cash flows and terminal value calculated as
discussed above. The results of such calculations are not necessarily indicative
of actual future cash flows or terminal values.
 
     Pro Forma Analysis.  Unterberg Harris analyzed certain pro forma effects
(excluding transaction costs) resulting from the Merger. For purposes of
comparison, SPC's operating results for the fiscal year ending September 30,
1997 were calendarized to a December 31, 1997 year using SPC management's
estimates. The analysis indicated, absent potential synergies, both SPC and
Allegro would generate significant operating losses for the year ending December
31, 1997; however, when considering potential operating efficiencies of the
combined company, the Merger provided significant improvement in operating
performance. The results of such pro forma combination analysis are not
necessarily indicative of future operating results or financial condition for
the combined company. Unterberg Harris also analyzed the contribution of SPC and
Allegro to the pro forma combined company in light of the SPC's stockholders'
ownership of the combined company being approximately 45%. This analysis showed
SPC projected to contribute 45.1% of combined revenues for the year ending
December 31, 1996 and 44.1% of combined revenues for the year ending December
31, 1997. Again, the results of such analysis is not necessarily indicative of
future operating results of the combined company or either company on a
stand-alone basis.
 
     The summary does not purport to be a complete description of the analyses
performed by Unterberg Harris in connection with its fairness opinion. The
preparation of a fairness opinion involves various subjective business
determinations as to the most appropriate and relevant methods of financial
analysis and the application of those methods to the particular circumstances,
and therefore such an opinion is not readily susceptible to partial analysis or
summary description. Accordingly, notwithstanding the separate factors
summarized above, Unterberg Harris believes that its analyses must be considered
as a whole and that selecting portions of its analyses or considering individual
factors without considering all analyses and factors could create an incomplete
and misleading view of the evaluation process underlying its opinion. With
respect to comparable companies analyses and comparable transaction analyses, a
particular analysis performed by Unterberg Harris is not necessarily indicative
of actual values, which may be significantly higher or lower than suggested by
such analyses. The analyses are not appraisals and do not necessarily reflect
the prices for which businesses actually could be sold or actual share prices or
future results that might be achieved. Unterberg Harris' analyses were prepared
solely as part of Unterberg Harris' review of the fairness of the consideration
to be received by SPC stockholders in connection with the Merger from a
financial point of view and were provided to the SPC Board in connection with
the delivery of Unterberg Harris' opinion. In addition, Unterberg Harris'
opinion and presentation to the SPC Board was only one of many factors taken
into consideration by the SPC Board in making its determination to approve the
Merger.
 
     Pursuant to the terms of the engagement by SPC of Unterberg Harris as its
financial advisor in connection with the Merger, upon consummation of the
Merger, Unterberg Harris will receive a fee of $600,000, of which $400,000 is
payable in cash and the remainder is payable in Allegro Common Stock. The terms
of the fee arrangement were negotiated at arm's length between SPC and Unterberg
Harris and approved by the SPC Board and Allegro. The SPC Board, in making its
recommendation with respect to the Merger and the Merger Agreement, was aware of
the foregoing fee arrangement.
 
     Unterberg Harris, as part of its investment banking business, is engaged in
the valuation of businesses and their securities in corporate reorganizations
and other purposes. The SPC Board selected Unterberg Harris to act as financial
advisor on the basis of Unterberg Harris' reputation as an investment bank,
SPC's prior relationship with Unterberg Harris and Unterberg Harris' familiarity
with SPC.
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following discussion summarizes the material federal income tax
considerations of the Merger that are generally applicable to holders of SPC
Common Stock. This discussion does not deal with all income tax considerations
that may be relevant to particular SPC stockholders in light of their particular
circumstances, such as stockholders who are dealers in securities, foreign
persons, stockholders who acquired their shares in connection with previous
mergers involving SPC or an affiliate, or stockholders who acquired their shares
in connection with stock option or stock purchase plans or in other compensatory
transactions. In addition, the
 
                                       51
<PAGE>   60
 
following discussion does not address the tax consequences of transactions
effectuated prior to or after the Merger (whether or not such transactions are
in connection with the Merger), including without limitation transactions in
which shares of SPC Common Stock were or are acquired or shares of Allegro
Common Stock were or are disposed of. Furthermore, no foreign, state or local
tax considerations are addressed herein. ACCORDINGLY, SPC STOCKHOLDERS ARE URGED
TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE
MERGER, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES TO THEM OF THE MERGER.
 
     The Merger is intended to constitute a "reorganization" within the meaning
of Section 368(a) of the Code, with each of Allegro, Merger Sub and SPC intended
to qualify as a "party to the reorganization" under Section 368(b) of the Code,
in which case the following federal income tax consequences will result (subject
to the limitations and qualifications referred to herein):
 
     (a) No gain or loss will be recognized by holders of SPC Common Stock
solely upon their receipt of Allegro Common Stock in the Merger in exchange
therefor (except to the extent of cash received in lieu of a fractional share
thereof);
 
     (b) The aggregate tax basis of the Allegro Common Stock received in the
Merger by a holder of SPC Common Stock will be the same as the aggregate tax
basis of such SPC Common Stock surrendered in exchange therefor;
 
     (c) The holding period of the Allegro Common Stock received in the Merger
by a holder of SPC Common Stock will include the period during which such
stockholder held the SPC Common Stock surrendered in exchange therefor, provided
that such SPC Common Stock is held as a capital asset at the time of the Merger;
 
     (d) Cash payments received by holders of SPC Common Stock in lieu of a
fractional share will be treated as if a fractional share of Allegro Common
Stock had been issued in the Merger and then redeemed by Allegro for cash. A
holder of SPC Common Stock will generally recognize gain or loss upon such
payment, equal to the difference (if any) between such holder's basis in the
fractional share and the amount of cash received; and
 
     (e) A holder of SPC Common Stock who exercises appraisal rights with
respect to all of such holder's shares of SPC Common Stock will generally
recognize gain or loss for federal income tax purposes, measured by the
difference between the holder's basis in such shares and the amount of cash
received, provided that the payment is neither essentially equivalent to a
dividend within the meaning of Section 302 of the Code nor has the effect of a
distribution of a dividend within the meaning of Section 356(a)(2) of the Code
(collectively, a "Dividend Equivalent Transaction"). Such gain or loss will be
capital gain or loss, provided that the SPC Common Stock is held as a capital
asset at the time of the Merger. A sale of SPC Common Stock pursuant to an
exercise of appraisal rights will generally not be a Dividend Equivalent
Transaction if, as a result of such exercise, the stockholder exercising
appraisal rights owns no shares of Allegro Common Stock or SPC Common Stock
(either actually or constructively within the meaning of Section 318 of the
Code). If, however, a stockholder's sale for cash of SPC Common Stock pursuant
to an exercise of appraisal rights is a Dividend Equivalent Transaction, then
such stockholder will generally recognize income for federal income tax purposes
in an amount up to the entire amount of cash so received.
 
     The parties are not requesting a ruling from the Internal Revenue Service
("IRS") in connection with the Merger. SPC has received an opinion from its
legal counsel, Wilson Sonsini Goodrich & Rosati, Professional Corporation, to
the effect that for federal income tax purposes, the Merger will constitute a
"reorganization" within the meaning of Section 368(a) of the Code. This opinion
(the "Tax Opinion") neither binds the IRS nor precludes the IRS from adopting a
contrary position. In addition, the Tax Opinion is subject to certain
assumptions and qualifications and is based on the truth and accuracy of certain
representations made by Allegro, Merger Sub, SPC and certain stockholders of
SPC, including representations in certificates delivered to counsel by the
respective managements of Allegro, Merger Sub, SPC and
 
                                       52
<PAGE>   61
 
certain stockholders of SPC. Of particular importance are those assumptions and
representations relating to the "continuity of interest" and the "continuity of
business enterprise" requirements.
 
     To satisfy the continuity of interest requirement, SPC stockholders must
not, pursuant to a plan or intent existing at or prior to the Merger, dispose of
or transfer so much of either (i) their SPC Common Stock in anticipation of the
Merger or (ii) the Allegro Common Stock to be received in the Merger
(collectively, "Planned Dispositions"), such that the SPC stockholders, as a
group, would no longer have a substantial proprietary interest in the SPC
business being conducted by the Combined Company after the Merger. Planned
Dispositions include, among other things, shares disposed of pursuant to the
exercise of appraisal rights. SPC stockholders will generally be regarded as
having retained a substantial proprietary interest as long as the Allegro Common
Stock received in the Merger (after reduction for any Planned Dispositions), in
the aggregate, represents a substantial portion of the entire consideration
received by the SPC stockholders in the Merger. To satisfy the "continuity of
business enterprise" requirement, Allegro must either (i) continue the historic
business conducted by SPC, or (ii) use a significant portion of the historic
business assets of SPC in a business.
 
     A successful IRS challenge to the "reorganization" status of the Merger (as
a result of a failure of the "continuity of interest" or "continuity of business
enterprise" requirements or otherwise) would result in an SPC stockholder
recognizing gain or loss with respect to each share of SPC Common Stock
surrendered equal to the difference between the stockholder's basis in such
share and the fair market value, as of the Effective Time of the Merger, of the
Allegro Common Stock received in exchange therefor. In such event, a
stockholder's aggregate basis in the Allegro Common Stock so received would
equal its fair market value and the holding period for such stock would begin
the day after the Merger.
 
NET OPERATING LOSS CARRYFORWARDS
 
     Allegro estimates its consolidated tax net operating loss carryforwards to
be approximately $10.2 million at September 30, 1996. SPC estimates its
consolidated tax net operating loss carryforwards to be approximately $69
million at September 30, 1996. Under Section 382 of the Code, certain changes in
the ownership or the business of a corporation that has net operating loss
carryforwards will result in the inability to use or the imposition of
significant restrictions on the use of such net operating loss carryforwards to
offset future income and the liability of such corporation. Allegro and SPC
expect that after giving effect to the Merger, an "ownership change" will be
deemed to have occurred under Section 382 of the Code and the regulations
thereunder with respect to both Allegro and SPC, and that as a result thereof
the use by the Combined Company of the net operating loss carryforwards of
Allegro and SPC will be limited. Utilization of the net operating loss
carryforwards of SPC may be further limited by reason of the consolidated return
separate return limitation year rules. There can be no assurance that the
Combined Company will be able to utilize all or any net operating loss
carryforwards of SPC or Allegro. In addition, the foreign losses incurred by SPC
may decrease or otherwise restrict the ability of the Combined Company to claim
U.S. tax credits for foreign income taxes. At or after the Effective Time,
Allegro expects to enter into a closing agreement with the Internal Revenue
Service pursuant to which Allegro would become jointly and severally liable for
SPC's tax obligations upon occurrence of a "triggering event" requiring
recapture of dual consolidated losses previously utilized by SPC. Such closing
agreement will avoid SPC being required to recognize a tax on approximately
$24.5 million of SPC's previous dual consolidated losses at the Effective Time.
Any future acquiror of the Combined Company may also be required to agree to a
similar closing agreement, to the extent it is able to do so. Non-U.S. persons
generally would be ineligible to do so. This could have a material adverse
effect on the future ability of the Combined Company to sell SPC to such an
ineligible person.
 
GOVERNMENTAL AND REGULATORY APPROVALS
 
     Allegro and SPC are aware of no governmental or regulatory approvals
required for consummation of the Merger, other than compliance with the federal
securities laws and applicable securities and "blue sky" laws of the various
states.

                              TERMS OF THE MERGER
 
EFFECTIVE TIME
 
     The Merger will become effective upon the filing of a Certificate of Merger
with the Secretary of State of the State of Delaware or at such later time as
may be agreed in writing by Allegro, SPC and Merger Sub and specified in the
Certificate of Merger (the "Effective Time"). The Closing Date will occur at a
time and date to be specified by Allegro, SPC and Merger Sub no later than the
second business day after the satisfaction or waiver of the conditions to the
Merger, or at such other time as Allegro, SPC and Merger Sub agree in writing.
Assuming all conditions to the Merger are met or waived prior thereto, it is
anticipated that the Closing Date and Effective Time will be on or about
December 31, 1996.
 
MANNER AND BASIS OF CONVERTING SHARES
 
     At the Effective Time of the Merger, Merger Sub will merge with and into
SPC and Allegro will own all of the capital stock of SPC. As a result of the
Merger, each outstanding share of SPC Common Stock, other than shares as to
which appraisal rights pursuant to the Delaware General Corporation Law have
been exercised and shares held in the treasury of SPC or owned by Merger Sub,
Allegro or any wholly owned subsidiary of Allegro or SPC, will be converted into
the right to receive 0.26805 shares of Allegro Common Stock, and each
outstanding option or right to purchase SPC Common Stock under the SPC Stock
Option Plans and SPC Stock Purchase Plan will be assumed by the Combined Company
and will become an option or right to purchase Allegro Common Stock, with
appropriate adjustments to be made to the number of shares issuable thereunder
and the exercise price thereof based on the Exchange Ratio. See "--Interests of
Certain Persons."
 
     No fractional shares will be issued by virtue of the Merger, but in lieu
thereof each holder of shares of SPC Common Stock who would otherwise be
entitled to a fraction of a share (after aggregating all fractional shares to be
received by such holder) will receive from Allegro an amount of cash (rounded to
the nearest whole cent) equal to the product of (i) such fraction, multiplied by
(ii) the average closing price of a share of Allegro Common Stock for the ten
most recent days that Allegro Common Stock has traded ending on the trading day
immediately prior to the Effective Time, as reported on Nasdaq.
 
     At or promptly after the Effective Time, the Combined Company, acting
through the Exchange Agent, will deliver to each SPC stockholder of record a
letter of transmittal with instructions to be used by such stockholder in
surrendering certificates which, prior to the Merger, represented shares of SPC
Common Stock. CERTIFICATES SHOULD NOT BE SURRENDERED BY THE HOLDERS OF SPC
COMMON STOCK UNTIL SUCH HOLDERS RECEIVE THE LETTER OF TRANSMITTAL FROM THE
EXCHANGE AGENT. At the Effective Time, each then-outstanding option to purchase
SPC Common Stock, whether vested or unvested, will be assumed by the Combined
Company without any action on the part of the holder thereof. OPTION AGREEMENTS
NEED NOT BE SURRENDERED.
 
     No later than ten business days after the Closing Date, the Combined
Company will file a registration statement on Form S-8 under the Securities Act
covering the shares of Allegro Common Stock issuable upon exercise of options to
purchase SPC Common Stock to be assumed by Allegro at the Effective Time.
 
STOCK OWNERSHIP FOLLOWING THE MERGER
 
     Based upon the capitalization of SPC as of the close of business on October
1, 1996 (including the number of shares of SPC Common Stock outstanding and the
number of shares issuable upon exercise of outstanding options to purchase SPC
Common Stock), and assuming that no holder of SPC Common Stock exercises
appraisal rights, an aggregate of approximately 3,372,825 shares of Allegro
Common Stock will be issued to SPC stockholders in the Merger and Allegro will
assume options for up to approximately 816,926 additional shares of Allegro
Common Stock. Based upon the number of shares of Allegro Common Stock issued and
outstanding as of October 1, 1996, and after giving effect to the issuance of
Allegro Common Stock as described in the previous sentence, the former holders
of SPC Common Stock would hold approximately 43.0% of the Combined Company's
total issued and outstanding shares, and would hold approximately 40.0%
 
                                       54
<PAGE>   63
 
of the voting power of the Combined Company, and holders of former SPC options
would hold options exercisable for approximately 9.9% of the Combined Company's
total issued and outstanding shares (assuming the exercise of only such
options). The foregoing numbers of shares and percentages are subject to change
in the event that the capitalization of either Allegro or SPC changes subsequent
to October 1, 1996 and prior to the Effective Time, and there can be no
assurance as to the actual capitalization of Allegro or SPC at the Effective
Time or of the Combined Company at any time following the Effective Time.
 
     As discussed above, Allegro will assume options for up to approximately
816,926 shares of Allegro Common Stock, based on 3,047,663 shares of SPC Common
Stock subject to outstanding options under the SPC Option Plans as of September
30, 1996. Pursuant to the terms of certain management continuity agreements
between SPC and its current officers and certain other key employees, the
vesting of options to purchase 1,575,000 of shares of SPC Common Stock
(representing approximately 422,178 shares of Allegro Common Stock after the
Merger) will be accelerated to the Effective Date as a result of the Merger. See
"Compensation and Other Information Concerning Directors and Officers of
SPC--Management Continuity Agreements." Notwithstanding the foregoing,
accelerated options representing 760,000 of such shares of SPC Common Stock
(representing approximately 203,718 shares of Allegro Common Stock after the
Merger) cannot be exercised until March 3, 1997, as a result of the imposition
of a six-month blackout period in conjunction with SPC's September 1996 option
repricing. In addition, options to purchase approximately 191,500 shares of SPC
Common Stock (representing approximately 51,332 shares of Allegro Common Stock
after the Merger) which are vested as of September 30, 1996 and are held by
employees who are not parties to management continuity agreements also cannot be
exercised until March 3, 1997 as a result of the imposition of a six-month
blackout period in conjunction with SPC's repricing of such options in September
1996. See "Compensation and Other Information Concerning Directors and Officers
of SPC--Repricing of Options."
 
CONDUCT OF ALLEGRO'S AND SPC'S BUSINESS PRIOR TO THE MERGER
 
     Pursuant to the Agreement, each of Allegro and SPC have agreed, on behalf
of itself and its subsidiaries, that during the period from the date of the
Agreement and continuing until the earlier of the termination of the Agreement
pursuant to its terms or the Effective Time, except as set forth in certain
disclosure schedules or to the extent that the other party shall otherwise
consent in writing, to carry on its business diligently and in accordance with
good commercial practice and to carry on its business in the usual, regular and
ordinary course, in substantially the same manner as theretofore conducted, to
pay its debts and taxes when due subject to good faith disputes over such debts
or taxes, to pay or perform other material obligations when due, and use its
commercially reasonable efforts consistent with past practices and policies to
preserve intact its present business organization, keep available the services

applicable law, Allegro and SPC have agreed to confer, as promptly as

LOAN FACILITY
 
     Pursuant to the Agreement, SPC has agreed to loan Allegro up to $1,000,000
(the "Loan Facility"). Funds may be advanced to Allegro in amounts not exceeding
$333,333 in any 30-day period. Funds advanced may be used only for working
capital purposes. In the event the Merger is not consummated for any reason, all
amounts advanced to Allegro under the Loan Facility will be automatically
converted into Allegro Common Stock at a conversion price of 90% of the average
of the last reported sales prices of Allegro Common Stock for the ten trading
days ending on the day immediately prior to the date of termination leading to
conversion of the amounts advanced under the Loan Facility (the "Loan Conversion
Price"); however, in the event the Agreement is terminated under circumstances
in which SPC is required to pay Allegro a termination fee, then only one-half of
the amounts advanced under the Loan Facility will be converted into Allegro
Common Stock at the Loan Conversion Price and the remaining one-half shall be
payable to SPC at the time and in the same manner as the payment of such
termination fee. As of October 28, 1996, no advances had been made under the
Loan Facility.
 
NO SOLICITATION BY SPC
 
     Under the terms of the Agreement, until the earlier of the Effective Time
or termination of the Agreement pursuant to its terms, SPC has agreed that it
and its subsidiaries will not, and will instruct their respective directors,
officers, employees, representatives, investment bankers, agents and affiliates
not to, directly or indirectly, (i) solicit or knowingly encourage submission
of, any proposals or offers by any person, entity or group (other than Allegro
and its affiliates, agents and representatives), or (ii) participate in any
discussions or negotiations with, or disclose any non-public information
concerning itself or any of its subsidiaries to, or afford any access to the
properties, books or records of itself or any of its subsidiaries to, or
otherwise assist or facilitate, or enter into any agreement or understanding
with, any person, entity or group (other Allegro and its affiliates, agents and
representatives), in connection with any Acquisition Proposal with respect to
itself. For the purposes of the Agreement, an "Acquisition Proposal" with
respect to an entity means any proposal or offer relating to (i) any merger,
consolidation, sale of substantial assets or similar transactions involving the
entity or any subsidiaries of the entity (other than sales of assets or
inventory in the ordinary course of business or permitted under the terms of the
Agreement), (ii) sale of 5% or more of the outstanding shares of capital stock
of the entity (including without limitation by way of a tender offer or an
exchange offer), (iii) the acquisition by any person of beneficial ownership or
a right to acquire beneficial ownership of, or the formation of any "group" (as
defined under Section 13(d) of the Exchange Act and the rules and regulations
thereunder) which beneficially owns, or has the right to acquire beneficial
ownership of, 5% or more of the then outstanding shares of capital stock of the
entity (except for acquisitions for passive investment purposes only in
circumstances where the person or group qualifies for and files a Schedule 13G
with respect thereto); or (iv) any public announcement of a proposal, plan or
intention to do any of the foregoing or any agreement to engage in any of the
foregoing. SPC has agreed to cease any and all existing activities, discussions
or negotiations with any parties conducted prior to the signing of the Agreement
with respect to any of the foregoing. SPC has agreed to (i) notify Allegro, as
promptly as practicable if any inquiry or proposal is made or any information or
access is requested in writing in connection with an Acquisition Proposal or
potential Acquisition Proposal and (ii) as promptly as practicable notify
Allegro of the significant terms and conditions of any such Acquisition
Proposal. In addition, subject to the other provisions set forth in this
section, from and after the date of the Agreement until the earlier of the
Effective Time and termination of the Agreement pursuant to its terms, SPC and
its subsidiaries have agreed to not, and have agreed to instruct their
respective directors, officers, employees, representatives, investment bankers,
agents and affiliates not to, directly or indirectly, make or authorize any
public statement, recommendation or solicitation in support of any Acquisition
Proposal made by any person, entity or group (other than Allegro); provided,
however, that nothing in the Agreement will prohibit the Board of Directors of
SPC from taking and disclosing to its stockholders a position with respect to a
tender offer pursuant to Rules 14d-9 and 14e-2 promulgated under the Exchange
Act.
 
     Notwithstanding the foregoing, prior to the approval of the Agreement by
the stockholders of SPC at the SPC Stockholders' meeting, SPC may, to the extent
its Board of Directors determines, in good faith, after
 
                                       57
<PAGE>   66
 
consultation with outside legal counsel, that the SPC Board's fiduciary duties
under applicable law require it to do so, participate in discussions or
negotiations with, and, subject to the requirements of the following paragraph,
furnish information to any person, entity or group after such person, entity or
group has delivered to SPC, as the case may be, in writing, an unsolicited bona
fide Acquisition Proposal which the Board of Directors of SPC in its good faith
reasonable judgment determines, after consultation with its independent
financial advisors, would result in a transaction more favorable to the
stockholders of SPC from a financial point of view than the Merger and for which
financing, to the extent required, is then committed or which, in the good faith
reasonable judgment of the Board of Directors of SPC (based upon the advice of
independent financial advisors), is reasonably capable of being financed by such
person, entity or group, and which is likely to be consummated (a "Superior
Proposal"). In the event SPC receives a Superior Proposal, nothing contained in
the Agreement will prevent the Board of Directors of SPC from approving such
Superior Proposal or recommending such Superior Proposal to SPC's stockholders,
if the SPC Board determines that such action is required by its fiduciary duties
under applicable law; provided, however, that SPC has agreed not to accept or
recommend to its stockholders, or enter into any agreement concerning, a
Superior Proposal for a period of not less than 48 hours after the receipt by
Allegro of a copy of such Superior Proposal (or a description of the significant
terms and conditions thereof, if not in writing).
 
BREAK UP FEES; EXPENSES
 
     Except as set forth below, all fees and expenses incurred in connection
with the Agreement and the transactions contemplated thereby will be paid by the
party incurring such expenses, whether or not the Merger is consummated.
 
     SPC has agreed that if it accepts a Superior Proposal, if the Board of
Directors of SPC recommends a Superior Proposal to the stockholders of SPC, or
if the stockholders of SPC fail to approve the Merger following a publicly
disclosed (and not withdrawn) Acquisition Proposal with regard to SPC or if the
stockholders of SPC fail to approve the Merger following the withholding,
withdrawal or modification by the Board of Directors of SPC, in a manner adverse
to Allegro, of its recommendation in favor of the Merger, then SPC will
immediately pay to Allegro the sum of $1.0 million. Each of Allegro and SPC have
agreed that, in the case of Allegro, if the Stockholders of Allegro fail to
approve the Merger and, in the case of SPC, if the stockholders of such company
fail to approve the Merger under circumstances not described in the preceding
sentences, and, in the case of either company, if such company fails to perform
or observe any of its covenants contained in the Agreement, then such company
will immediately pay to the other party the sum of $750,000.

TERMINATION OF THE AGREEMENT
 
     The Agreement provides that it may be terminated at any time prior to the
Effective Time of the Merger, whether before or after approval of the Merger by
the stockholders of Allegro and SPC: (a) by mutual written consent duly
authorized by the Boards of Directors of Allegro and SPC; (b) by either Allegro
or SPC if the Merger shall not have been consummated by February 15, 1997
(provided, however, that the right to so terminate the Agreement shall not be
available to any party whose action or failure to act has been a principal cause
of or resulted in the failure of the Merger to occur on or before such date and
such action or failure to act constitutes a breach of the Agreement); (c) by
either Allegro or SPC if a court of competent jurisdiction or governmental,

permanently restraining, enjoining or otherwise prohibiting the Merger, which
order, decree or ruling is final and nonappealable; (d) by either Allegro or SPC

stockholder approval
 
                                       59
<PAGE>   68
 
of such party shall have been caused by the action or failure to act of such
party in breach of the Agreement); (e) by either Allegro or SPC, if SPC shall
have accepted a Superior Proposal or by Allegro if the SPC Board recommends an
SPC Superior Proposal to the stockholders of SPC; (f) by Allegro, if the SPC
Board shall have withheld, withdrawn or modified in a manner adverse to Allegro
its recommendation in favor of approving the issuance of the shares of Allegro
Common Stock by virtue of the Merger; (g) by SPC, if the Allegro Board shall

the Agreement, or if any representation or warranty of SPC shall have become
untrue in any material respect, in either case such that the conditions set
forth in subsections (a) and (b) of the second to last paragraph of the
preceding section would not be satisfied as of the time of such breach or as of
the time such representation or warranty shall have become untrue (provided that
if such inaccuracy in Allegro's representations and warranties or breach by
Allegro is curable by Allegro through the exercise of its commercially

warranty shall have become untrue or such breach, then SPC may not so terminate
the Agreement during such fifteen-day period provided Allegro continues to

preceding section would not be satisfied as of the time of such breach or as of
the time such representation or warranty shall have become untrue (provided,
that if such inaccuracy in SPC's representations and warranties or breach by SPC
is curable by SPC through the exercise of its commercially reasonable efforts
within fifteen (15) days of the time such representation or warranty shall have
become untrue or such breach, then Allegro may not so terminate the Agreement
during such fifteen-day period provided SPC continues to exercise such
commercially reasonable efforts); (j) by SPC, if there shall have occurred any
material adverse effect with respect to Allegro since the date of the Agreement;
(k) by Allegro, if there shall have occurred any material adverse effect with
respect to SPC since the date of the Agreement; (l) by SPC, if it has not
received the Unterberg Harris Opinion or other investment banking firm opinion
by October 11, 1996; or (m) by Allegro, if it has not received the Frost Opinion
or other investment banking firm opinion by October 11, 1996.
 
     Each of the Unterberg Harris Opinion and the Frost Opinion was delivered on
or prior to October 11, 1996. See "Approval of the Merger and Related
Transactions--Opinion of SPC's Financial Advisor" and "-- Opinion of Allegro's
Financial Advisor."
 
AFFILIATE AGREEMENT
 
     Fred Gibbons, Chairman of the Board of Directors of SPC, has entered into
an agreement restricting sales, dispositions or other transactions reducing his
risk of investment in respect of the shares of SPC Common Stock held by him
prior to the Merger and the shares of Allegro Common Stock received by him in
the Merger so as to comply with the requirements of applicable federal
securities and tax laws.
 
INTERESTS OF CERTAIN PERSONS
 
  SPC Options
 
     SPC has entered into certain Management Continuity Agreements (the
"Management Continuity Agreements") with each of its current officers, Daniel J.
Fraisl, Miriam K. Frazer and Joseph V. Szczepaniak, and with three other key
non-officer employees. See "Compensation and Other Information Concerning
Directors and Officers of SPC--Management Continuity Agreements" and "Terms of
the Merger--Stock Ownership Following the Merger". Under the terms of such
Management Continuity Agreements, in the event there is a "Change of Control" of
SPC, which is defined in the Management Continuity Agreements to include, among
other things, a merger or sale of assets of SPC, the exercisability and vesting
of all options held by such persons are accelerated. Accordingly, the
consummation of the Merger will cause the acceleration of the vesting of options
to purchase 1,575,000 shares of SPC Common Stock (representing 422,178 shares of
Allegro Common Stock after the Merger) to the Effective Date. (Notwithstanding
the foregoing, accelerated options representing 760,000 shares of SPC Common
Stock (representing 203,718 shares of Allegro Common
 
                                       60
<PAGE>   69
 
Stock after the Merger) cannot be exercised until March 3, 1997, as a result of
the imposition of a six-month blackout period in conjunction with SPC's
repricing of such options in September 1996. See "Compensation and Other
Information Concerning Directors and Officers of SPC--Repricing of Options."
 
  Employment Agreements
 
     In addition to the option acceleration provisions described above, the
Management Continuity Agreements with Ms. Frazer, Mr. Szczepaniak and Mr. Fraisl
provide that in the event that such officer is "involuntarily terminated" within
18 months after a Change of Control, the officer receives 12 months severance
pay and continued health and medical benefits. Severance benefits to which an
officer may become entitled under the Management Continuity Agreements are
reduced by an amount equal to the fair market value of any accelerated options
less the exercise price for such accelerated options.
 
     Miriam Frazer and Joseph V. Szczepaniak have entered into employment
agreements with Allegro, which will become effective at the Effective Time,
which employment agreements amend substantially the terms of their Management
Continuity Agreements, and thus their employment with SPC. Similarly, Daniel
Fraisl has entered into an amendment to his existing employment agreement with
SPC, which amendment also becomes effective at the Effective Time, which
amendment modifies substantially the terms of his employment with SPC.
 
     Pursuant to Ms. Frazer's employment agreement with Allegro, Ms. Frazer will
receive (i) a base salary of $140,000 per year, (ii) a bonus of $40,000, (iii) a
bonus of $40,000 upon Allegro's attainment of certain agreed upon performance
targets, (iv) subject to the approval of Allegro's stockholders of an increase
to no less than 2,500,000 in the number of shares available under the Allegro
Incentive Plan, options to purchase 170,000 shares of Allegro Common Stock at an
exercise price equal to the fair market value thereof on the date of grant,
exercisable in equal installments on the first, second, third and fourth
anniversaries of the date of grant or in full upon a change of control of
Allegro (as defined in the employment agreement) and (v) in the event of her
termination other than for cause or within twelve months of a change of control
of Allegro, payment of her base salary for one year plus the amount of any
accrued but unpaid bonuses, which payment would be made in a lump sum less an
amount equal to the fair market value of any accelerated options less the
exercise price therefor in the event of a termination following a change of
control; provided, that in no event can Allegro terminate Ms. Frazer other than
for cause prior to June 1, 1997. Pursuant to Ms. Frazer's existing employment
agreement with SPC, she was entitled to a base salary of $178,000 per year, a
performance based bonus of up to 30% of her annual salary and was terminable at
will, other than in the event of a change of control of SPC in which event she
was entitled to receive an amount equal to her base salary for one year reduced
by an amount equal to the fair market value of any accelerated options less the
exercise price for such accelerated options.
 
     Pursuant to Mr. Szczepaniak's employment agreement with Allegro, Mr.
Szczepaniak will receive (i) a base salary of $135,000 per year, (ii) a bonus of
$45,000, (iii) a bonus of $20,000 upon Allegro's attainment of certain agreed
upon performance targets, (iv) subject to the approval of Allegro's stockholders
of an increase to no less than 2,500,000 in the number of shares available under
the Allegro Incentive Plan, options to purchase 170,000 shares of Allegro Common
Stock at an exercise price equal to the fair market value thereof on the date of
grant, exercisable in equal installments on the first, second, third and fourth
anniversaries of the date of grant or in full upon a change of control of
Allegro and (v) in the event of his termination other than for cause or within
twelve months of a change of control of Allegro, a payment of his base salary
for one year plus the amount of any accrued but unpaid bonuses, which payment
would be made in a lump sum less an amount equal to the fair market value of any
accelerated options less the exercise price therefor in the event of a
termination following a change of control; provided, that in no event can
Allegro terminate Mr. Szczepaniak other than for cause prior to June 1, 1997.
Pursuant to Mr. Szczepaniak's existing employment agreement with SPC, he was
entitled to a base salary of $165,000 per year, a performance based bonus of up
to 30% of his annual salary and was terminable at will other than in the event
of a change of control of SPC in which event he was entitled to receive an
amount equal to his base salary for one year reduced by an amount equal to the
fair market value of any accelerated options less the exercise price for such
accelerated options.

     Pursuant to the amendment to Mr. Fraisl's employment agreement, Mr. Fraisl
is to be employed by SPC until April 17, 1998, and will receive (i) a base
salary of $130,000 per year, (ii) a bonus of $25,000, (iii) a bonus of $25,000
upon SPC's attainment of certain agreed upon performance targets, (iv) subject
to the approval of Allegro's stockholders of an increase to no less than
2,500,000 in the number of shares available under the Allegro Incentive Plan,
options to purchase at an exercise price equal to the fair market value thereof
on the date of grant, exercisable in equal installments, 110,000 shares of
Allegro Common Stock on the first, second, third and fourth anniversaries of the
date of grant or in full upon a change of control of Allegro, (v) options to
purchase up to three additional increments of 50,000 shares of Allegro Common
Stock each at an exercise price equal to the fair market value thereof on the
date of grant upon the release in calender 1997 of a major new electronic mail
product utilizing SPC's "Intelligent Formatting" technology, and the release in
each of calendar 1998 and 1999 of an additional major new product utilizing
SPC's "Intelligent Formatting" technology and (vi) in the event of his
termination other than for just cause, will be entitled to receive payment of
his base salary for one year plus the amount of any accrued but unpaid bonuses,
which payment would be made in a lump sum less an amount equal to the fair
market value of any accelerated options less the exercise price therefor in the
event of a termination following a change of control. Pursuant to Mr. Fraisl's
existing employment agreement with SPC, he was entitled to a base salary of
$150,000 per year, a performance based bonus of up to 10% of his annual salary
and was terminable at will, other than in the event of a change of control of
SPC in which event he was entitled to receive an amount equal to his base salary
for one year reduced by an amount equal to the fair market value of any
accelerated options less the exercise price for such accelerated options.
 
  Other Agreements
 
     Digital Paper, Inc. ("Digital Paper"), and its stockholders, one of whom is
Daniel Fraisl, have entered into an amendment to the Stock Purchase Agreement by
which SPC acquired Digital Paper, effective at the Effective Time. The amendment
provides that a remaining payment of $1,650,000, which is required by the terms
of the Stock Purchase Agreement to be made by SPC to Digital Paper in cash or in
shares of SPC Common Stock, shall, pursuant to the terms of the amendment, be
paid in cash or in Allegro Common Stock, at the option of each such stockholder.
 
     The Board of Directors of Allegro has determined to pay to each of Barry A.
Cinnamon and Mark E. Leininger a bonus of $25,000 following the first profitable
fiscal quarter of the Combined Company, and to increase Mr. Leininger's salary
to $145,000 per annum effective at the Effective Time.
 
     The Board of Directors of SPC has determined to pay a bonus of $25,000 to
each of Miriam K. Frazer, Daniel J. Fraisl and Joseph V. Szczepaniak, payable
following the first profitable fiscal quarter of the Combined Company.
 
  Indemnification
 
     Section 145 of the Delaware General Corporation Law provides that
indemnification of directors, officers, employees and other agents of a
corporation, and persons who serve at its request as directors, officers,
employees or other agents of another organization, may be provided by it.
 
     SPC's Certificate of Incorporation includes provisions eliminating the
personal liability of its directors for monetary damages resulting from breaches
of their fiduciary duty except, pursuant to the limitations of the Delaware
General Corporation Law (i) for any breach of the director's duty of loyalty to
SPC or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or any amendatory or
successor provisions thereto, or (iv) with respect to any transaction from which
the director derived an improper personal benefit. SPC's By-laws provide
indemnification to directors and officers and permit indemnification for
employees and agents, including against claims brought under state or Federal
securities laws, to the full extent allowable under Delaware law. SPC also has
entered into indemnification agreements with its directors and executive
officers providing, among other things, that SPC will provide defense costs
against any such claim, subject to reimbursement in certain events. SPC also
maintains a directors and officers
 
                                       62

liability insurance policy. Allegro has agreed pursuant to the Agreement to
maintain SPC's current directors and officers liability insurance policies in
effect until September 3, 1997 with respect to former directors and officers of
SPC and that to the extent that SPC fails to pay in full any retentions or
deductibles payable thereunder by indemnified parties, Allegro shall pay such
amounts.
 
     Allegro's Certificate includes provisions eliminating the personal
liability of its directors for monetary damages resulting from breaches of their
fiduciary duty except, pursuant to the limitations of the Delaware General
Corporation Law (i) for any breach of the director's duty of loyalty to Allegro
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or any amendatory or

APPRAISAL RIGHTS
 
     If the Agreement is approved by the required vote of SPC stockholders and
the Merger becomes effective, holders of SPC Common Stock who did not vote to
approve the Agreement may, by complying with Section 262 of the Delaware General
Corporation Law, be entitled to appraisal rights as described therein
("Appraisal Rights"). The stockholders of record of SPC Common Stock which are
eligible to, and do, exercise their Appraisal Rights with respect to the Merger
are referred to herein as "SPC Dissenting Stockholders," and the shares of SPC
Common Stock with respect to which they exercise Appraisal Rights are referred
to herein as "Dissenting Shares." If an SPC stockholder has a beneficial
interest in shares of SPC Common Stock that are held of record in the name of
another person, and such stockholder desires to perfect whatever Appraisal
Rights such beneficial stockholder may have, such beneficial stockholder must
act promptly to cause the stockholder of record timely and properly to follow
the steps summarized below.
 
     Pursuant to the Delaware General Corporation Law, a stockholder of SPC may
dissent from the proposed corporate action to approve the Agreement and receive
the right to an appraisal of such stockholder's shares. Attached hereto as Annex
D is a copy of Section 262 of the Delaware General Corporation Law.
 
     If the Merger is consummated, the SPC Dissenting Stockholders will be
entitled, if they strictly comply with the provisions of the Delaware General
Corporation Law, to have the fair value of their shares of SPC Common Stock
judicially determined and paid to them. The following discussion is not a
complete statement of the Delaware General Corporation Law relating to Appraisal
Rights, and is qualified in its entirety by reference to Section 262 of the
Delaware General Corporation Law attached to this Prospectus/Joint Proxy
Statement as Annex D and incorporated herein by reference. This discussion and
Section 262 of the Delaware General Corporation Law should be reviewed carefully
by any stockholder who wishes to exercise statutory Appraisal Rights or wishes
to preserve the right to do so, since failure to comply with the required
procedures will result in the loss of such rights. A stockholder of SPC who
votes for the adoption and approval of the Merger will be deemed to have waived
such stockholder's right to exercise Appraisal Rights with respect to all shares
of SPC Common Stock held by such stockholder. Any holder who is considering
dissenting should consult his or her legal advisor.
 
     1. To exercise Appraisal Rights, a stockholder must (1) file with SPC,
before the taking of the stockholders' vote on the approval of the Agreement at
the SPC Meeting, a written objection to the Agreement stating the intention of
such stockholder to demand payment for shares of SPC Common Stock owned by such
stockholder if the Agreement is approved and the Merger becomes effective, and
(2) the stockholder must not vote in favor of the Agreement. A vote in favor of
the Agreement will waive such stockholder's Appraisal Rights. However, a
stockholder's failure to vote on the Agreement will not in itself be a waiver of
such holder's Appraisal Rights. A proxy or vote against the Agreement does not,
alone, constitute demand. A stockholder who dissents and demands Appraisal
Rights must do so as to all shares of SPC
 
                                       63
<PAGE>   72
 
Common Stock held by such stockholder. A stockholder may not assert Appraisal
Rights with respect to less than all of such stockholder's shares of SPC Common
Stock.
 
     2. Within 120 days after the Effective Time of the Merger, the Combined
Company or any stockholder who gave notice, before the taking of the
stockholders' vote on the Agreement at the SPC Meeting, of such stockholder's
objection to the Agreement and who did not vote in favor of the Agreement and
who otherwise complied with the Delaware General Corporation Law, may file a
petition in the Court of Chancery in the State of Delaware demanding a
determination of the value of the Dissenting Shares of all such stockholders.
 
     3. Upon the filing of any such petition by a stockholder, a copy must be
served on the Combined Company.
 
     4. At the hearing on the petition, the Court shall determine the
stockholders who have complied with the Delaware General Corporation Law and who
have become entitled to appraisal rights. The Court shall then determine the
fair value of the Dissenting Shares and shall order the Combined Company to make
payment of such value, together with interest, to the SPC Dissenting
Stockholders entitled to said payment, subject to receipt of duly endorsed
certificates for the Dissenting Shares. Pursuant to the Delaware General
Corporation Law, the fair value of the Dissenting Shares is the value determined
by the Court taking into account all relevant factors, excluding any element of
value arising from the expectation or accomplishment of the Merger. The "fair
value" of the Dissenting Shares could be more than, the same as or less than the
value of SPC Common Stock on the date of the determination of the Exchange
Ratio. All court costs, including appraisers' fees, shall be allocated by the
Court in a manner it determines to be fair and equitable.
 
     5. Upon consummation of the Merger, each SPC Dissenting Stockholder will
cease to have any rights of a stockholder except the right to be paid the fair
value of the Dissenting Shares and the right to receive other distributions, if
any, payable to a stockholder of record prior to the Effective Time and any
other rights under applicable Delaware law.
 
COMBINED COMPANY FOLLOWING THE MERGER
 
     Once the Merger is consummated, Merger Sub will cease to exist as a
corporation, and all of the business, assets, liabilities and obligations of
Merger Sub will be merged into SPC, with SPC remaining as the surviving
corporation (the "Surviving Corporation"). Following the Merger, the
headquarters of the Combined Company initially will be located in San Jose,
California. At the Effective Time of the Merger, Allegro and SPC expect that the
Combined Company will have approximately 130-140 employees at its principal
facilities in the United States and the United Kingdom.
 
     Pursuant to the Agreement, the Certificate of Incorporation of Merger Sub
in effect immediately prior to the Effective Time will become the Certificate of
Incorporation of the Surviving Corporation and the By-laws of Merger Sub will
become the By-laws of the Surviving Corporation. The Board of Directors of the
Surviving Corporation will consist of the directors who are serving as directors
of Merger Sub immediately prior to the Effective Time. The officers of Merger
Sub immediately prior to the Effective Time will remain as officers of the
Surviving Corporation, until their successors are duly elected or appointed or
qualified.
 
     Following the Effective Time and pursuant to the Agreement, the Combined
Company's Board of Directors will take action to cause the Board of Directors of
the Combined Company, immediately after the Effective Time, to consist of up to
eleven persons, up to nine of whom have served on the Board of Directors of
Allegro immediately prior to the Effective Time and two of whom will have served
on the SPC Board (one of whom is expected to be Fred Gibbons, in Class III, and
one of whom is expected to be Miriam Frazer, in Class II). If, prior to the
Effective Time, any of the Allegro directors resign, the Allegro Board will have
the right to replace such director, and if either of the SPC designees decline
or are unable to serve as directors of the Combined Company, then SPC will have
the right to designate another person to serve in such person's stead, which
person must be reasonably acceptable to Allegro. The Board of Directors of the
Combined Company will retain the right and power to select the members of its
Audit Committee and its Compensation Committee.
 
                                       64
<PAGE>   73
 
     Pursuant to the Agreement, at the Effective Time, Barry A. Cinnamon will
continue to be the Chairman of the Board, President and Chief Executive Officer
of the Combined Company, Mark Leininger will continue to be the Vice President,
Chief Operating Officer and Treasurer of the Combined Company, Miriam Frazer
will become the Vice President-Finance and Chief Financial Officer of the
Combined Company, Daniel Fraisl will become the Vice President-Research and
Development of the Combined Company, Joseph Szczepaniak will become Vice
President-Sales and Marketing of the Combined Company, James Tsonas will be Vice
President-Corporate Sales of the Combined Company and Lori Kramer Cinnamon will
continue to be Assistant Vice President-Marketing.
 
     The SPC Board and the Allegro Board believe that the Combined Company may
have the potential to realize long-term improved operating and financial results
and a stronger competitive position. Allegro and SPC believe that there is a
strategic fit among their business productivity and visual communications
software products. Allegro and SPC also believe that the Merger will provide
greater opportunities to develop business relationships, license technology, and
engage in other strategic combinations and transactions involving their
respective products and technologies than would be the case if the companies
otherwise independently engaged in these activities. In this way, the Merger
could provide the Combined Company with the range of products and services
required to play a significant role in the evolving market for visual
communications business productivity and visual communications software.
 
     Following the Effective Date of the Merger, Allegro and SPC intend that the
Combined Company follow a strategy of producing visual communication
productivity software for the SOHO and corporate, desktop and Internet/Intranet
markets. This productivity software is expected to utilize Intelligent
Formatting technology to provide a potential competitive advantage compared to
product offerings of other companies. In doing so the Combined Company will
merge the business strategies of Allegro and SPC. See "Allegro--Allegro
Business" and "SPC--SPC Business Strategy."
 
     Software created by the Combined Company is expected to build on the
technical strengths and proprietary technology of both Allegro and SPC. This
software is expected to help business users, who are not computer specialists,
quickly produce professional appearing, high-quality, graphically rich
documents. These products are expected to incorporate SPC's Intelligent
Formatting technology, which is designed to allow users who are not computer
specialists to create well designed documents using simple high level commands.
With Intelligent Formatting, the non-specialist user is able to manipulate
graphic design factors such as layout, design, and color, and the program
automatically correlates these factors to create an effective and visually
pleasing document.
 
     Allegro and SPC believe that Intelligent Formatting technology may provide
strategic advantages to users of distributed computer networks such as the
Internet/Intranet because Intelligent Formatting requires only unformatted text,
along with a small amount of additional information, to be stored in the file
and sent across the network. Graphical formatting of the document is derived
on-the-fly by the Intelligent Formatting engine as the object is viewed,
substituting relatively abundant local computing power for relatively scarce
network transmission bandwidth. Allegro and SPC believe that this small
footprint software technology is ideally suited to the current data
communications limitations of the Internet caused by the relatively low
transmission speeds of conventional telephone lines and dial-up communication
modems.
 
     However, the anticipated benefits of the Merger will depend in part on
whether the companies' operations can be integrated in an efficient and
effective manner. There can be no assurance that this will occur. The
combination of the companies will require, among other things, integration of
the companies' respective product offerings and coordination of the companies'
sales, marketing and research and development efforts. Historically, the sales
models used by Allegro's and SPC's sales organizations have differed
significantly. There can be no assurance that the Combined Company will be able
to take full advantage of the combined sales forces' efforts. Allegro and SPC
also use a number of distribution channels in the various geographic markets in
which their respective products are sold, and there can be no assurance that
channel conflict will not develop following the Merger as the Combined Company
attempts to integrate these channels.
 
     The success of the integration process will be significantly influenced by
the ability of the Combined Company to attract and retain key management, sales,
marketing and research and development personnel,
 
                                       65
<PAGE>   74
 
while concurrently minimizing the Combined Company's costs and expenses. There
is no assurance that the foregoing will be accomplished smoothly or
successfully. The integration of operations following the Merger will require
the dedication of management resources, which may distract attention from the
day-to-day operations of the Combined Company. The inability of management to
successfully integrate the operations of the companies could have a material
adverse effect upon the business, operating results and financial condition of
the Combined Company. Allegro has recently completed the acquisition of Serif,
and the Combined Company may acquire other companies, products or technologies
in the future. There can be no assurance that these acquisitions and the Merger
with SPC can be effectively integrated, that such acquisitions will not result
in costs or liabilities that could materially and adversely affect the Combined
Company's business, operating results and financial condition, or that the
Combined Company will obtain the anticipated or desired benefits of such
transactions. See "Risk Factors" for additional risks associated with the
Merger.

         PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS (UNAUDITED)
 
     The following pro forma condensed combined financial statements (unaudited)
are based on the historical financial statements of Allegro (audited for the
year December 31, 1995 and unaudited at September 30, 1996 and for the nine
months then ended), Serif, Inc. and Serif (Europe) Ltd. (collectively, "Serif")
(audited for the year ended December 31, 1995 and unaudited for the period
January 1, 1996 to July 31, 1996) (See Note 1 below) and SPC (audited for the
year ended September 30, 1995 and unaudited for the nine months ended September
30, 1996). The pro forma condensed combined balance sheet assumes that the
Merger of Allegro and SPC occurred as of September 30, 1996. The pro forma
condensed combined statements of operations give effect to the acquisition of
Serif and the Merger, assuming the transactions were completed at the beginning
of the respective periods. The pro forma condensed combined financial statements
have been prepared assuming the Merger has been accounted for under the purchase
method of accounting and estimating the fair value of Allegro Common Stock to be
$ 5.25 per share. (See Note 1 to the Pro Forma Condensed Combined Financial
Statements.) If the Merger is consummated under the proposed terms thereof,
management of Allegro anticipates that approximately $14,200,000 of the
aggregate purchase price will be allocated to in-process research and
development, which will result in a charge to operations of this amount in the
period in which the Merger is consummated.
 
     The pro forma condensed combined statements of operations are not
necessarily indicative of operating results which would have been achieved had
these transactions been completed at the beginning of the respective periods and
should not be construed as representative of future operations. These pro forma
condensed combined financial statements should be read in conjunction with the
historical financial statements of Allegro, Serif and SPC, including the notes
thereto, "Allegro Management's Discussion and Analysis of Financial Condition
and Results of Operations," "SPC Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the notes to these pro forma
financial statements.

   NOTES TO THE PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS (UNAUDITED)
 
1. DESCRIPTION OF TRANSACTION
 
     On July 31, 1996, Allegro acquired all of the outstanding common stock of
Serif Inc. and all of the outstanding preferred and common stock of Serif
(Europe) Limited (collectively, "Serif"). The aggregate purchase price was
approximately $4,850,000, which consisted of 1,000,000 shares of Allegro Common
Stock. The transaction has been accounted for using the purchase method of
accounting. Under the purchase method of accounting, the assets and liabilities
have been adjusted to their preliminary estimated fair values based upon
available information and are subject to revision. As a result of the
preliminary purchase price allocation, a charge to earnings of approximately
$3,886,000 was recorded on the date of acquisition representing the cost
assigned to in-process research and development.
 
     On October 1, 1996, Allegro, Merger Sub and SPC entered into an Agreement
and Plan of Reorganization. Under the terms of the Agreement, the transaction
will be completed through the exchange of SPC Common Stock for shares of Allegro
Common Stock according to a share conversion ratio of 0.26805 shares of Allegro
Common Stock for each share of SPC Common Stock. As a result of the merger,
Merger Sub will merge with and into SPC, resulting in SPC becoming a
wholly-owned subsidiary of Allegro. Based on an estimated price of $5.25 per
share of Allegro Common Stock (closing price on October 25, 1995) and other
direct costs of approximately $2,000,000, the aggregate purchase price will be
approximately $20,186,000. The transaction will be accounted for as a purchase.
For purposes of the Pro Forma Condensed Combined Financial Statements, the
assets and liabilities of SPC have been adjusted to their preliminary estimated
fair values based upon available information and are subject to revision.

     The combined Allegro pro forma statements of operations exclude the
nonrecurring charge for in-process research and development resulting from the
Serif acquisitions. The combined pro forma statements of operations exclude the
anticipated nonrecurring charge of approximately $14.2 million for in-process
research and development expected to result from the acquisition of SPC by
Allegro.
 
3. QUARTERLY OPERATING RESULTS
 
     SPC had total revenues of $5,011,000 and a net loss of $(2,238,000) during
the three-month period ended December 31, 1995. Operating results of SPC for the
three months ended December 31, 1995 have
 
                                       71
<PAGE>   80
 
been excluded from the pro forma financial statements. For purposes of the Pro
Forma Condensed Combined Statement of Operations for the year ended December 31,
1995, SPC's results of operations for the twelve months ended September 30, 1995
have been included. For purposes of the Pro Forma Condensed Combined Statement
of Operations for the nine months ended September 30, 1996, SPC's results of
operations for the nine months ended September 30, 1996 have been included.
 
4. COSTS OF INTEGRATION
 
     As a result of the Merger, Allegro and SPC expect to incur an additional
significant charge to operations, which is currently expected not to exceed $5
million, in the quarter in which the Merger is consummated, to reflect costs
associated with integrating the two companies. The accompanying Pro Forma
Condensed Combined Financial Statements do not reflect any such additional costs
which may ultimately be incurred.

                  ADDITIONAL MATTERS BEING SUBMITTED TO A VOTE
                          OF ONLY ALLEGRO STOCKHOLDERS
 
PROPOSAL TWO--AMENDMENT TO CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER
OF AUTHORIZED SHARES OF ALLEGRO COMMON STOCK
 
     Allegro's Certificate provides that the number of shares of Allegro Common
Stock which Allegro is authorized to issue is 18,000,000. The Allegro Board has
determined that, in connection with the Agreement, it is advisable to increase
the number of authorized shares of Allegro Common Stock to 30,000,000, and has
authorized such amendment to the Certificate at the Effective Time, subject to
stockholder approval, as more fully set forth in Annex E hereto. Under the
proposed amendment, subject to and upon consummation of the Merger, Article
Fourth (a) of the Certificate would be amended and restated to read as follows:
 
     "The total number of shares of all classes of stock which the corporation
shall have authority to issue is THIRTY-FOUR MILLION (34,000,000) shares. Of
these (i) THIRTY MILLION (30,000,000) shares shall be shares of Common Stock of
the par value of $.001 per share; (ii) TWO MILLION (2,000,000) shares shall be
shares of Class A Convertible Preferred Stock of the par value of $.001 per
share; and (iii) TWO MILLION (2,000,000) shares shall be shares of Serial
Preferred Stock of the par value of $.001 per share."
 
     If the proposal is approved by the shareholders of Allegro as described
below, the additional shares of Allegro Common Stock may be issued from time to
time upon authorization of the Board of Directors, without further approval by
the stockholders unless required by applicable law, and for such consideration
as the Allegro Board of Directors may determine and as may be permitted by
applicable law. The availability of additional shares of Allegro Common Stock
for issuance will afford Allegro greater flexibility in acting upon proposed
transactions.
 
     The increase in authorized shares is not being proposed as a means of
preventing or dissuading a change in control or takeover of Allegro. However,
use of these shares for such a purpose is possible. Shares of authorized but
unissued or unreserved Allegro Common Stock and Preferred Stock, for example,
could be issued in an effort to dilute the stock ownership and voting power of
persons seeking to obtain control of Allegro or could be issued to purchasers
who would support the Board of Directors in opposing a takeover proposal. In
addition, the increase in authorized shares, if approved, may have the effect of
discouraging a challenge for control or making it less likely that such a
challenge, if attempted, would be successful.
 
     The proposed amendment does not change the terms of the Allegro Common
Stock, which does not have preemptive rights. The additional shares of Allegro
Common Stock for which authorization is sought will have the same voting rights,
the same rights to dividends and distribution and will be identical in all other
respects to the shares of Allegro Common Stock now authorized.
 
     The Allegro stockholders are being asked to approve such amendment. The
affirmative vote of the holders of a majority of the shares of Allegro Common
Stock issued and outstanding on the Allegro Record Date and the affirmative vote
of the holders of a majority of the shares of Allegro's Class B Voting Preferred
Stock issued and outstanding on the Allegro Record Date, each voting separately
as a class, will be required to approve this amendment to the Certificate. The
effect of an abstention is the same as that of a vote "against" the proposal.
 
     THE ALLEGRO BOARD UNANIMOUSLY RECOMMENDS THAT THE ALLEGRO STOCKHOLDERS VOTE
"FOR" THE AMENDMENT TO THE ALLEGRO CERTIFICATE OF INCORPORATION TO INCREASE THE
NUMBER OF AUTHORIZED SHARES OF ALLEGRO COMMON STOCK TO 30,000,000, SUBJECT TO
AND UPON CONSUMMATION OF THE MERGER.
 
PROPOSAL THREE--AMENDMENT TO CERTIFICATE OF INCORPORATION TO ELIMINATE CLASS A
CONVERTIBLE PREFERRED STOCK
 
     Allegro's Certificate provides for the issuance of 2,000,000 shares of
Class A Convertible Preferred Stock, par value $.001 per share. An aggregate of
1,190,250 shares of Class A Convertible Preferred Stock were issued in June and
November 1994 in connection with a private placement transaction. All of these
shares of
 
                                       73
<PAGE>   82
 
Class A Convertible Preferred Stock automatically converted into 491,821 shares
of Allegro Common Stock upon the completion of Allegro's initial public
offering.
 
     As there are no longer any shares of Class A Convertible Preferred Stock
issued and outstanding and the Board of Directors has no present intention to
issue any additional shares of Class A Convertible Preferred Stock, the Board of
Directors has determined that it is advisable to amend the Certificate to
eliminate the Class A Convertible Preferred Stock, and has authorized such
amendment to the Certificate at the Effective Time, subject to stockholder
approval, as more fully set forth in Annex F hereto. The terms of Allegro's
Class B Voting Preferred Stock, Series A, which was created by the Board of
Directors in November 1994, 60,520 shares of which Serial Preferred Stock, par
value $.001 per share are issued and outstanding and owned of record by Barry A.
Cinnamon, will be unaffected by the adoption of this proposal. Under the
proposed amendment, subject to and upon consummation of the Merger, and assuming
that proposal (2) is adopted, Article Fourth (a) of the Certificate would be
amended to read as follows:
 
     "The total number of shares of all classes of stock which the corporation
shall have authority to issue is THIRTY-TWO MILLION (32,000,000) shares. Of
these (i) THIRTY MILLION (30,000,000) shares shall be shares of Common Stock of
the par value of $.001 per share; (ii) ONE MILLION NINE HUNDRED THIRTY-NINE
THOUSAND FOUR HUNDRED EIGHTY (1,939,480) shares shall be shares of Serial
Preferred Stock of the par value of $.001 per share; and (iii) SIXTY-THOUSAND
FIVE HUNDRED TWENTY (60,520) shares shall be shares of Class B Voting Preferred
Stock, Series A, of the par value of $.001 per share."
 
     The Allegro stockholders are being asked to approve such amendment. The
affirmative vote of the holders of a majority of the shares of Allegro Common
Stock and the Class B Voting Preferred Stock issued and outstanding on the
Allegro Record Date, voting together as a class, will be required to approve
this amendment of the Certificate. The effect of an abstention is the same as
that of a vote "against" the proposal.
 
     THE ALLEGRO BOARD UNANIMOUSLY RECOMMENDS THAT THE ALLEGRO STOCKHOLDERS VOTE
"FOR" THE AMENDMENT OF THE ALLEGRO CERTIFICATE OF INCORPORATION TO ELIMINATE THE
CLASS A CONVERTIBLE PREFERRED STOCK.
 
PROPOSAL FOUR--AMENDMENT OF THE 1994 LONG TERM INCENTIVE PLAN
 
     Allegro's 1994 Long Term Incentive Plan (the "Allegro Incentive Plan") was
initially adopted by the Allegro Board on December 23, 1993 and initially
approved by the Allegro stockholders on December 24, 1993. The Allegro Incentive
Plan authorizes the grant of stock, stock options or other awards to employees,
non-employee directors and consultants of the Combined Company. A total of
400,000 shares of Allegro Common Stock was originally available for grant and
reserved for issuance under the Allegro Incentive Plan, which was increased to
1,000,000 shares on September 5, 1996. Options granted under the Allegro
Incentive Plan may be either "incentive stock options" as defined in Section 422
of the Code, or nonstatutory stock options, as determined by the Long Term
Incentive Plan Administrative Committee. Stock appreciation rights, restricted
stock, performance grants and other types of awards may also be granted under
the Allegro Incentive Plan.
 
     The Allegro Incentive Plan is administered by the Long Term Incentive Plan
Administrative Committee of the Allegro Board of Directors (currently comprised
of Marc E. Jaffe and George Lauro) who determine, among other things, the
individuals to whom, and the time or times at which, options shall be granted,
the number of shares to be subject to each option, the purchase price of the
shares and the term of each option, with the exception that no incentive stock
options generally can be granted at an exercise price of less than the fair
market value of shares of Allegro Common Stock on the date of grant, and no
non-qualified stock options can be granted at an exercise price of less than 85%
of such fair market value and options may only be exercised before the
expiration of ten years from the date of grant. Each option granted under the
Plan may be exercised only during the continuance of an optionee's employment or
service with Allegro.
 
     On September 30, 1996, the Allegro Board approved a further increase of
2,000,000 shares (approximately 20.3% of Allegro Common Stock to be outstanding
or issuable following the Merger, based on the capitalization of SPC and Allegro
on October 1, 1996) available for grant under the Allegro Incentive Plan,
 
                                       74
<PAGE>   83
 
which, if approved by the Allegro stockholders, would increase the total shares
available for grant and reserved for issuance under the Allegro Incentive Plan
since its inception and as of the date immediately following approval of this
proposal to 3,000,000 shares. A copy of the Allegro Incentive Plan, as amended
pursuant to this proposal, is attached as Annex G hereto.
 
     As of October 28, 1996, options to purchase 928,237 shares of Allegro
Common Stock granted under the Allegro Incentive Plan were outstanding, of which
65,001 were exercisable, 71,763 shares remained available for future option
grants and no options had been exercised. Options to purchase an aggregate of
510,000 shares of Allegro Common Stock have been agreed to be granted, subject
to the consummation of the Merger and to stockholder approval of this proposal
(4), to five employees of SPC, three of whom are members of SPC management. See
"Terms of the Merger--Interests of Certain Persons".
 
     Allegro stockholders are requested to approve the amendment to the Allegro
Incentive Plan to increase the number of shares available for grant thereunder.
The Allegro Board believes this amendment is in the best interests of the
Combined Company following the Merger, as the increase can contribute to
ensuring that the Combined Company will have an adequate number of shares
available for grant under the Allegro Incentive Plan, thereby enabling the
Combined Company to provide additional long term incentives to help retain key
personnel in the Combined Company following the Merger.
 
     The affirmative vote of a majority of the votes cast with regard to this
proposal will be required to approve the amendment to the Allegro Incentive
Plan. Abstentions will be counted toward the number of shares represented and
voting at the Allegro Meeting.
 
     THE ALLEGRO BOARD UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE AMENDMENT OF THE
ALLEGRO INCENTIVE PLAN TO INCREASE THE NUMBER OF SHARES AVAILABLE FOR GRANT
THEREUNDER.
 
Federal Income Tax Consequences
 
  Incentive Stock Options
 
     An optionee who is granted an incentive stock option does not recognize
taxable income at the time the option is granted or upon its exercise, although
the exercise may subject the optionee to the alternative minimum tax. Upon a
disposition of the shares more than two years after grant of the option and one
year after exercise of the option, any gain or loss is treated as long-term
capital gain or loss. If these holding periods are not satisfied, the optionee
recognizes ordinary income at the time of disposition equal to the difference
between the exercise price and the lower of (i) the fair market value of the
shares at the date of the option exercise or (ii) the sale price of the shares.
Any gain or loss recognized on such a premature disposition of the shares in
excess of the amount treated as ordinary income is treated as long-term or
short-term capital gain or loss, depending on the holding period. A different
rule for measuring ordinary income upon such a premature disposition may apply
if the optionee is also an officer, director, or 10% Stockholder. Allegro is
entitled to a deduction in the same amount as the ordinary income recognized by
the optionee.
 
  Nonstatutory Stock Options
 
     An optionee does not recognize any taxable income at the time he or she is
granted a nonstatutory stock option. Upon exercise, the optionee recognizes
taxable income generally measured by the excess of the then fair market value of
the shares over the exercise price. Any taxable income recognized in connection
with an option exercise by an employee of Allegro is subject to tax withholding
by Allegro. Allegro is entitled to a deduction in the same amount as the
ordinary income recognized by the optionee. Upon a disposition of such shares by
the optionee, any difference between the sale price and the optionee's exercise
price, to the extent not recognized as taxable income as provided above, is
treated as long-term or short-term capital gain or loss, depending on the
holding period.
 
  Stock Appreciation Rights
 
     No income will be recognized by a recipient in connection with the grant of
a stock appreciation right. When the stock appreciation right is exercised, the
recipient generally will be required to include as taxable
 
                                       75
<PAGE>   84
 
ordinary income in the year of exercise an amount equal to the sum of the cash
received and the fair market value of any Allegro Common Stock received on the
exercise. In the case of a recipient who is also an employee, any income
recognized on exercise of a stock appreciation right will constitute wages for
which withholding will be required. Allegro will be entitled to a tax deduction
in the same amount. If the optionee receives Allegro Common Stock upon the
exercise of a stock appreciation right, any gain or loss on the subsequent sale
of such stock will be treated in the same manner as discussed above under
"Nonstatutory Stock Options."
 
  Restricted Stock
 
     Under current law, no taxable income for federal income tax purposes will
be realized by the participants who receive restricted stock for the year in
which the shares are purchased by the participant. However, the employee has the
right to elect to include in his or her taxable income for that year an amount
equal to the excess of the market value of such shares over his or her cost at
the time of acquisition. If the employee does make such an election, the amount
included in taxable income may not be deducted later if he or she should be
required to resell the shares to Allegro. If the employee does not make this
election, he or she will realize taxable income, and a tax deduction will be
available to Allegro, for federal income tax purposes for the year in which
Allegro's option to repurchase the shares expires, in an amount equal to the
difference between the employee's cost of the Restricted Stock and the market
value of unrestricted shares on the day the restrictions expire or are removed.
 
     The foregoing is only a summary of the effect of federal income taxation
upon optionees and Allegro and other participants with respect to the grant and
exercise of options, stock appreciation rights and restricted stock under the
Allegro Incentive Plan. It does not purport to be complete, and does not discuss
the tax consequences of the employee's or consultant's death or the provisions
of the income tax laws of any municipality, state or foreign country in which
the employee or consultant may reside.

                                    ALLEGRO
 
ALLEGRO BUSINESS
 
BACKGROUND
 
     Allegro is a publisher of business productivity and interactive multimedia
computer software primarily for the corporate and SOHO computer software
markets. Allegro is a Delaware corporation which was incorporated and merged in
December 1993 with its predecessor New Jersey corporation, which was formed in
July 1992. In July 1996, Allegro acquired Serif, Inc. and Serif (Europe) Limited
(collectively, "Serif"), which publish, sell and market desktop publishing
computer software. Allegro, directly and through Serif, currently sells
thirty-one (31) software titles in four product categories: desktop publishing,
business productivity, business reference and tutorials. Many of Allegro's
products are distinguished by licensed brand names such as Entrepreneur(@)
Magazine, as well as Allegro's own Learn to Do(@) brand. In addition, Allegro's
acquisition in July 1996 of Serif significantly expanded Allegro's desktop
publishing product line to include recent new releases PagePlus(TM) Home/Office,
DrawPlus(TM) 3.0, Publishing Power Suite and PagePlus(TM) 4.0 Professional
Edition. Allegro also publishes and sells certain home reference and family
lifestyle titles, which Allegro does not plan to emphasize in the future.
 
     Allegro's strategy is to expand its product line with additional business
productivity products, which may include brand name content, and to supplement
its line of business productivity products with additional visual communications
and other products for the corporate and the SOHO market niches in which a
significant market share is believed to be attainable by management. Allegro
believes that the market for visual communications and business productivity
software products will continue to grow as the installed base of personal
computers and color printers grows, and as the ease of use of these software
products and the Internet increases among corporate and SOHO customers. In
addition, the popularity of the Internet and its World Wide Web network is
expected to make it possible for virtually every personal computer to be
connected, thereby spurring demand for information and software that can be
shared and transmitted. As the Internet evolves mechanisms for efficiently and
securely charging customers for this software and information, Allegro
anticipates that it will become feasible for companies to distribute their
products over the Internet, thereby circumventing traditional forms of software
information and distribution. Allegro believes that it has the capability to
become a provider of software and business content over the Internet and other
on-line media; however, no assurance can be given that Allegro will be able to
successfully sell its products over on-line media.
 
     Allegro's products currently are primarily available on the Windows(@)95
and 3.1 operating systems. Allegro has created a linkage from several of its
CD-ROM products to the Prodigy(@) and CompuServe(@) on-line services, and
intends to create linkages to Allegro's Internet site and potentially other
commercial on-line services. Use of these on-line and Internet linkages is
intended to enhance the features and appeal of its products and to allow Allegro
to generate additional revenue sources from on-line sales of its products, to
the extent such on-line sales become commercially feasible, as well as to
enhance Allegro's marketing efforts. In September 1996, Allegro introduced its
BusinessPlus World Wide Web site to attempt to more effectively market and sell
its products over the Internet. No assurance can be given that Allegro will be
successful in these regards, particularly given the difficulties currently
encountered in arranging for secure payment facilities through on-line networks
and concerns regarding unauthorized reproduction of software.
 
     Allegro sells its products to a broad range of customers, including
software retailers, computer superstores, wholesale clubs, mall-based chains,
consumer electronics stores, office superstores, bookstores, original equipment
manufacturers ("OEMs") and direct to end-users. Sales are made to these accounts
either through distributors, or directly by Allegro, including by direct mail.
Allegro utilizes a network of independent sales representatives to service and
merchandise its products to these accounts. Allegro's products are currently
available in retail stores such as Best Buy, CompUSA, Computer City, Electronics
Boutique, Micro Center, Babbages, Software Etc., Egghead Discount Software,
Staples, Office Depot and OfficeMax, as well as major software retailers in the
UK. Allegro also operates telesales centers in Nashua, New Hampshire and
Nottingham, England, the efforts of which generally are coordinated with direct
sales campaigns.
 
                                       77
<PAGE>   86
 
     Allegro attempts to carefully manage its new product development process.
This process is intended to be responsive to the needs of the current and
anticipated near future market, and stresses rapid development on a
cost-effective basis while seeking to maintain quality and end user
satisfaction. Development efforts are managed by an internal development staff
which is complemented by a network of independent development contractors.
Products are manufactured by a variety of packaging and production contractors.
Warehousing and shipping functions are primarily performed internally. Allegro
believes that this use of outside development, production and manufacturing
services enables Allegro to create quality products quickly, while at the same
time minimizing fixed costs and related overhead.
 
PRODUCTS
 
     Allegro creates product lines in market niches in which it believes, based
on management's experience, that it can attain a significant market share, and
that have an identifiable market. Allegro believes that its product line
approach helps contribute to brand awareness of other titles in the series.
Funds expended for sales and marketing awareness, both at the retail and
consumer level, are generally spread across multiple titles in a series and
accrue benefits to Allegro as upgrades and new titles are offered in subsequent
years. Allegro generally sets suggested list prices for its products; however,
Allegro's suggested list prices and actual selling prices may vary from time to
time, and actual selling prices through most retail outlets typically range
between approximately 25% to 35% less than Allegro's suggested list price.
 
     Customer preferences for software products are difficult to predict, and
few software products achieve sustained market acceptance. Allegro is dependent
on the market acceptance of its existing products and the continued development
and introduction of new products which achieve market acceptance. In this
connection, Allegro has attempted to concentrate its new product development
efforts on products which Allegro believes may have a more extended product life
cycle, such as its PagePlus(TM) desktop publishing titles, which Allegro expects
to be able to continue to sell for longer periods with periodic updates. Allegro
has also implemented targeted sales and marketing programs which attempt to
maximize sales of older backlist titles in appropriate sales channels primarily
by selling such products at reduced prices.
 
     Allegro's small office/home business category includes four primary product
lines: desktop publishing, business productivity, business reference and
tutorials. Allegro's desktop publishing line includes PagePlus(TM) Home/Office,
DrawPlus(TM) 3.0, Publishing Power Suite and PagePlus(TM) Professional Edition.
Allegro's business productivity line includes Berlitz(@) Executive Travel, its
business reference line includes its Entrepreneur(@) Magazine products, and its
tutorial line consists of Allegro's own Learn to Do(@) products. Allegro's home
reference and family lifestyle categories, which Allegro does not intend to
emphasize in the future, currently consist of one home reference and two cooking
products, respectively. As a result of the number of existing and updated titles
in each product line, coupled with special editions of certain titles for
specific customers, Allegro is not dependent on any single product nor on a
single major customer to sell its products. There can be no assurance that
Allegro's existing or new products will achieve market acceptance, or sustain
any such acceptance for any significant period, and Allegro may adjust its
product offerings and sales and marketing strategies in light of these
circumstances. All of Allegro's products work on Microsoft Windows(@).
 
LICENSES AND PROPRIETARY RIGHTS
 
  Intellectual Property Rights
 
     Allegro regards the software that it publishes as proprietary, and relies
primarily on a combination of copyrights, trade secret laws, patent and
trademark laws, third party nondisclosure agreements and other methods to
protect its products and proprietary rights. Allegro also has several registered
trademarks. Although several of Allegro's trademarks have been issued
Certificates of Registration by the United States Patent and Trademark Office,
it is possible that there may exist a prior user or users of a confusingly
similar mark or marks for similar goods and/or services. In such an event,
Allegro could be compelled to change its trademarks and thereby lose goodwill.
Allegro has instituted a policy generally requiring that its employees and third
party developers sign nondisclosure and proprietary rights agreements. Allegro
has a copyright in all of its proprietary software used in its products, but has
a registered copyright in only one of the several versions
 
                                       78
<PAGE>   87
 
of such proprietary software and several pending applications for registration
of copyrighted materials. Allegro does not have any mechanism to copy-protect
its software, and relies on copyright laws to prevent unauthorized copying.
Unauthorized copying of software occurs in the software industry, and Allegro's
business, operating results and financial condition could be adversely affected
if copying of Allegro's products becomes significant. Because of the large
amount of data associated with Allegro's CD-ROM software, it is currently more
difficult (although not impossible) for individual customers to copy most of
Allegro's software compared to traditional diskette software which is less
commonly used by Allegro. Certain Allegro software is available for download
over the Internet; enforced registration and timelock codes are used to minimize
the impact of unauthorized copying.
 
     Allegro believes that its products, trademarks and other proprietary rights
do not infringe on the proprietary rights of third parties in any material
respect. Allegro has not been the subject of any intellectual property
litigation.
 
  Content Licenses
 
     Allegro has acquired content licenses from publishers, popular authors and
celebrities, and Allegro intends to continue to acquire rights to properties and
talent which will support its marketing strategy. In license agreements, Allegro
seeks: (i) reasonably long terms for the license, at least 2-5 years; (ii)
customary advance guarantees and royalty rates; (iii) artistic and editorial
cooperation of the licensor; and (iv) to the extent available on a
cost-effective basis, exclusive rights to publish in various or all electronic
formats, in each case including CD-ROM. Allegro's current license agreements
grant to Allegro the right to publish its CD-ROM products only on CD-ROM, except
that Allegro has the exclusive electronic publishing rights to its Serif
products and its Cooking with Dom DeLuise product. Due to the nature of many of
Allegro's products, licenses or company production of content is often required
for certain audio, video and written materials to supplement original content
provided by the primary licensor. For each particular product being developed,
Allegro seeks to obtain content licenses from various authors and other rights
holders, or to produce its own content, as the development of the product
progresses. Licensing costs may be expected to rise with increased competition
in the electronic publishing industry. Allegro also relies on certain software
that it licenses or has licensed from third parties, including software that is
integrated with internally developed software and used in its products to
perform key functions. In addition, if media other than CD-ROM (such as on-line
services or the Internet) become popular for computer software products such as
those produced by Allegro, Allegro would be required to license the content used
in connection with its products for such media, or else it will not be permitted
to sell such products on such platforms. There can be no assurance that Allegro
will be able to obtain renewals of such licenses or new licenses, as the case
may be, on commercially reasonable terms.
 
PRODUCT DEVELOPMENT
 
     Allegro is currently expanding its product line with additional software
titles for the corporate and SOHO markets. During the nine months ended
September 30, 1996, the fiscal year ended December 31, 1995 and the fiscal year
ended December 31, 1994, Allegro spent approximately $597,738, $295,878 and
$298,755, respectively, for development of new products. This represents
approximately 6%, 17% and 24%, respectively, of total operating expenses for
each period. Product development costs are integrated into the cost and pricing
of each product.
 
     Allegro has developed a product development model that transforms new
product ideas into products as quickly and affordably as practical, thereby
seeking to minimize investment risks for each product. Once a product is
approved for development, a project leader is assigned to develop a detailed set
of specifications, time frame and budget. These materials are reviewed in detail
by Allegro's executive management, and are modified on an as needed basis to
reflect market demand, product release schedules and budgetary considerations.
The project leader produces the new product with a team that may include
programmers, electronic editors, graphic artists, animators, video editors,
sound editors, writers, designers and quality assurance testers. Generally,
product design, software programming and editing functions are performed by
in-house employees, while graphics, video and audio editing activities are
performed by outside independent contractors. Products have been developed in
Allegro's offices in the United States and England. Allegro
 
                                       79
<PAGE>   88
 
performs quality assurance reviews of its products and then tests for bugs,
functionality, ease-of-use and compatibility with a variety of popular PC
configurations that are available to consumers.
 
     Allegro's senior marketing and sales executives incorporate the new
products into their marketing and sales plans to attempt to produce marketing
materials and make preliminary sales substantially concurrently with product
releases. Allegro's development, marketing and sales staff evaluate Allegro's
products and compare them to customer needs and potentially competitive
products. These comparisons form part of the basis for product upgrades, product
revisions and new product ideas. Allegro has several products which currently
utilize on-line services and is in the process of increasing its development of
on-line related products, including products based in the Java computer
language, to address a potential long-term shift to these new forms of
electronic product delivery.
 
SALES AND MARKETING
 
     Allegro relies primarily on three basic sales channels: retail sales,
direct mail and OEMs. Allegro sells its products through distributors and on a
direct basis to retailers such as software specialty stores, computer
superstores, office superstores, office supply stores, warehouse clubs, mall
based chains, consumer electronics stores, mass merchants and bookstores.
Retailers in the United States purchasing Allegro's products directly from
Allegro or through distributors over the past 12 months include Best Buy,
CompUSA, Computer City, Electronics Boutique, Micro Center, Babbages, Software
Etc., Egghead Discount Software, Staples, Office Depot and OfficeMax. Retailers
in the United Kingdom purchasing Allegro's products over the past 12 months
include PC World and Dixon's. Distributors of Allegro's products include Ingram
Micro, Inc., Tech Data, Merisel and Navarre Corp. Allegro maintains a list of
its registered user customers and sends periodic mailings to sell upgrade
versions and new products. Allegro also utilizes its telesales operations in
conjunction with its direct mail operations to maximize direct sales to existing
and new end user customers. These mailings originate from Allegro's offices in
the United States and England and are handled by Allegro's inbound and outbound
telemarketers in Nashua, New Hampshire and Nottingham, England. Mailings are
varied and tested to attempt to maximize response rates and profitability.
Allegro sells to a variety of OEMs who include Allegro's products in bundles
with their equipment. OEMs to which Allegro has sold products include IBM, AST,
Philips, Twinhead and Xerox.
 
     Allegro uses an internal staff and a network of sales representatives to
obtain orders from retail accounts. Five regional sales representative firms
obtain orders for Allegro's products from major retail accounts in the United
States and Canada, and a national book sales representative firm obtains orders
for Allegro's products from regional and independent bookstores. GuildSoft, a
sales representative firm, obtains orders for Allegro's products from retail
accounts in the United Kingdom. International sales and strategic partnership
programs are managed by Allegro's Vice President-Business Development. Allegro's
sales representatives and in-house sales staff attempt to work with retail
buyers to try to assure that retailers are carrying the appropriate Allegro
products for their retail outlet, that stocking levels are adequate, that
promotions and advertising are coordinated with product releases and that
in-store merchandising plans are properly implemented.
 
     Allegro's marketing department is responsible for creating and executing
marketing programs to generate product sell-in (sales to retailers) and
sell-through (sales to end-user customers). These programs generally are based
on established consumer product marketing techniques. Allegro uses consumer
product graphic designers and copywriters to attempt to create effective package
designs, catalogs, brochures, advertisements and related materials. Allegro's
marketing and sales departments work together to coordinate retail and publicity
programs generally to be in place when products are initially shipped to
retailers and consumers. Public relation campaigns, in-store advertising,
catalog mailings and advertisements are generally designed in advance of product
availability. Allegro's Vice President-Marketing specializes in direct mail
sales and supervises Allegro's direct mail and telesales operations.
 
     Allegro provides telephone and Internet technical support to its customers
at no additional charge. To date, the call volume to Allegro's support staff has
been within industry norms. Allegro believes that its efforts to create high
quality, easy-to-install products, coupled with these in-house and Internet
support facilities, are sufficient to meet anticipated customer technical
support needs for the foreseeable future.
 
                                       80
<PAGE>   89
 
     Allegro is exposed to returns by distributors, retailers and consumers.
Reserves for these returns have been established by Allegro that it believes are
adequate based on product sell-through, inventory levels and historic return
rates. Allegro generally accepts returns from customers, even when not legally
required to do so, in order to maintain good continuing relationships with these
customers and to sell its latest product releases to these customers. Allegro
periodically adjusts its reserves for these returns. Allegro sells to major
accounts on credit, with varying discounts, return privileges and credit terms.
These sales are not collateralized. Significant deterioration in accounts
receivable collections could have an adverse effect on Allegro's financial
condition, operating results and overall business.
 
COMPETITION
 
     The market for business productivity software is intensely competitive.
Allegro believes that the principal competitive factors in the corporate and
SOHO categories generally include overall product and content, brand name
recognition, ease of use, merchandising, product features, reliability, on-line
technology, distribution channels and price. Allegro competes primarily with
other software publishers. Allegro's competitors vary in size from very small
companies with limited resources to very large corporations with greater
financial, marketing, distribution, technical and other resources. Although
there are a variety of consumer and business software publishers, based on
product lines and price points, Allegro currently regards Microsoft, Symantec,
Corel, SoftKey International, Expert Software, Individual Software, Inc. and
IMSI as its closest competitors. In addition, it is possible that certain large
software companies, hardware companies and media companies may increasingly
target the corporate and SOHO niches, resulting in additional competition. Based
on its current and anticipated future product offerings, Allegro believes that
it competes or will compete effectively in these areas, particularly in the way
of brand name recognition, ease of use product features and through on-line
technology; however, no assurance can be given that Allegro's products will
achieve market acceptance or that if they do so, that such market acceptance can
be sustained. See "Risk Factors--Competition".
 
OPERATIONS
 
     Allegro coordinates accounting, purchasing, inventory control and
scheduling related to its U.S. and UK operations at its offices in Fairfield,
New Jersey and Nottingham, England; Allegro coordinates order processing,
warehousing and shipping activities related to such operations at its offices in
Fairfield, New Jersey, Nashua, New Hampshire and Nottingham, England. Production
and major vendor initial shipments are performed by independent contractors
working under Allegro's direction. Allegro's computer system handles order
entry, order processing, picking, billing, accounts receivable, accounts
payable, general ledger, inventory control, catalog management and analysis, and
mailing list management. Subject to credit terms and product availability,
orders are typically shipped from Allegro's facilities within 24 hours of
receiving an order. Third party contractors generally print and assemble the
CD-ROM discs, diskettes, manuals, catalog inserts and boxes in which Allegro's
products are shipped. Allegro has multiple sources for major components of its
products, does not rely on any one principal supplier and has not experienced
any material delays in production or assembly.
 
GOVERNMENTAL REGULATIONS
 
     To its knowledge, Allegro does not need any government approval for
production and sale of its products. In addition, Allegro knows of no
governmental regulations, either federal, state or local which specifically
affect its operations or products. In addition, Allegro knows of no
environmental laws, either federal, state or local, which would affect Allegro
or its products. Consequently, Allegro has not incurred any costs nor has it
experienced any affects from compliance from any governmental regulations or
environmental laws.
 
EMPLOYEES
 
     As of September 30, 1996, Allegro had approximately 102 full-time
employees. In addition, Allegro utilizes approximately five independent
contractors in connection with its product development activities. Allegro's
employees are not represented by a labor union and are not subject to any
collective bargaining
 
                                       81
<PAGE>   90
 
arrangement. Allegro has never experienced a work stoppage and believes that it
has good relations with its employees and contractors.
 
DESCRIPTION OF PROPERTY
 
     In May 1996, Allegro entered into a three-year lease for approximately
13,400 square feet of office and warehouse space in Fairfield, New Jersey, which
space Allegro uses for its offices and warehouse. In addition, Serif leases
approximately 7,600 square feet of office and warehouse space in Nashua, New
Hampshire pursuant to a lease ending in April 1997, and approximately 6,000
square feet of office and warehouse space in Nottingham, England pursuant to a
month-to-month lease. Allegro believes that this space, together with SPC's
available space, will provide Allegro with adequate space for the foreseeable
future. Allegro does not own nor does it contemplate owning any real property in
the foreseeable future.
 
LEGAL PROCEEDINGS
 
     Allegro is not involved in any pending legal proceedings which are expected
to have a material effect on the financial condition of Allegro.

                ALLEGRO MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the historical
financial statements, including the notes thereto, of Allegro included elsewhere
herein.
 
GENERAL
 
     Allegro designs, develops and markets a line of computer software products
principally for the SOHO and small business markets and intends to de-emphasize
its family lifestyle and home reference product lines upon completion of the
Merger. Allegro currently derives substantially all of its net sales from
products sold by its direct mail and call centers, its internal sales force and
independent sales representatives to retailers, distributors and OEMs.
 
     The development of Allegro's software publishing business has involved the
development of proprietary computer software, the licensing of CD-ROM and, in
certain instances, other electronic publishing rights to content, and the
creation and conversion of original and supplemental text, video, audio,
graphics and animation. Allegro's continued growth is expected to require
increases in the number of Allegro's employees, expenditures for new product
development, the acquisition of licensing or product rights, sales and marketing
expenses, and general and administrative expenses relating to the development of
a management infrastructure and facilities necessary to support Allegro's
growth.
 
     Costs of goods sold consists primarily of product costs, freight charges,
royalties and an inventory allowance for damaged and obsolete products. Product
costs consist of the costs to purchase the underlying materials and print both
boxes and manuals, media costs (CD-ROMs and other media) and assembly. The
product development costs associated with Allegro's products are expensed as
incurred.
 
RESULTS OF OPERATIONS
 
  Nine Months Ended September 30, 1996 Compared to Nine Months Ended September
30, 1995
 
     Net Sales.  Net sales increased approximately 180% from $913,041 in the
nine month period ended September 30, 1995 to $2,554,937 in the nine month
period ended September 30, 1996, largely as a result of inclusion of the sales
from Allegro's Serif subsidiaries for two months in the 1996 period. There are
no Serif results included in the 1995 period. Allegro's year-over-year
comparable sales results increased 38%. As a result of an increased number of
products and increased sales to certain larger customers, Allegro provided in
the nine month period ended September 30, 1996 for returns at approximately 25%
of gross sales versus approximately 20% in the nine month period ended September
30, 1995.
 
     Cost of Goods Sold.  On a year-over-year basis, cost of goods sold
increased approximately 69% or $299,498 from the nine month period ended
September 30, 1995 versus the nine month period ended September 30, 1996 largely
due to increased sales volumes. Cost of goods sold decreased as a percentage of
net sales from approximately 47% in the nine month period ended September 30,
1995 to approximately 29% in the nine month period ended September 30, 1996, as
a result of increased sales volume providing lower per unit production costs and
a change in product mix.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased by $4,635,883 or approximately 469% from
$987,996 in the nine month period ended September 30, 1995 to $5,623,831 in the
nine month period ended September 30, 1996. Expenses in the nine month period
ended September 30, 1996 include a charge to compensation expense of $2,135,200
due to the release of 314,000 shares of common stock from escrow in September
and $637,980 in compensation expense related to the release from escrow of
217,000 shares of common stock in April to two management stockholders. In
addition to the escrow release, the 1996 expenses include expenses for two
months of operations of Allegro's Serif operations which are not included in the
1995 period. Total selling expenses increased approximately 305% from $243,875
in nine month period ended September 30, 1995 to $987,437 in the nine month
period ended September 30, 1996, primarily as a result of Allegro's direct mail
operations and increased advertising. Bad debt expense increased by
approximately $180,572 due to the Chapter 11 bankruptcy filing of one of its
software distributors.
 
                                       83

     Product Development.  Product development expenses increased approximately
139% from $249,894 in the nine month period ended September 30, 1995 to $597,738
in the nine month period ended September 30, 1996, primarily as a result of
Allegro expensing $243,750 relating to the acquisition of a developmental
software program, Allegro's development of new Serif products and continued
development of proposed new Internet products. Allegro believes that development
expenses will increase in dollar amount in the future as Allegro expands its
development activities, although Allegro's long-term goal is to continue to
reduce product development costs as a percentage of sales. All development costs
have been expensed in the period incurred.
 
     In-Process Research and Development.  In the nine month period ended
September 30, 1996, based on a preliminary allocation of the Serif purchase
price, Allegro expensed $3,886,000 of in-process research and development costs
associated with the acquisition of the Serif companies.
 
     Other Income.  In the nine month period ended September 30, 1996, Allegro
received other income of $135,663 versus a net expense of $71,678 in the nine
month period ended September 30, 1995, primarily as a result of higher cash
balances and royalty income. Allegro had no royalty income in 1995.
 
  1995 Compared to 1994
 
     Net Sales.  Net sales increased approximately 40% from $1,006,131 in the
year ended December 31, 1994 ("1994"), to $1,410,962 in the year ended December
31, 1995 ("1995"). This increase in net sales was largely attributable to the
greater number of products offered by Allegro, including Entrepreneur(@),
Berlitz(@), and Cooking with Dom DeLuise(TM). Allegro's two largest customers in
1995, Ingram Micro, Inc. and Navarre Corp. accounted for approximately 23% and
13% of net sales, respectively, and Allegro's five largest customers accounted
for approximately 55% of Allegro's net sales. In 1994, Allegro's four largest
customers, Babbages, ABCO Distributors, Computer City Supercenters and Navarre
Corp., each accounted for approximately 11% of Allegro's net sales while
Allegro's five largest customers accounted for approximately 52% of Allegro's
net sales. As a result of increased product offerings related to Allegro's
newest titles and a focus on sales to certain larger customers, Allegro provided
in 1995 for returns at approximately 22% of gross sales versus approximately 27%
in 1994.
 
     Cost of Goods Sold.  Cost of goods sold increased approximately 93% from
$411,506 in 1994 to $795,730 in 1995, as a result of increased sales volume
resulting in higher royalties and production costs of approximately $176,300. As
a percentage of net sales, cost of goods sold increased from approximately 41%
of net sales in 1994 to approximately 56% of net sales in 1995. Material costs
in 1994 were favorably impacted by a larger sales volume of lower cost products.
The material cost increase in 1995 resulted primarily from an increase in
replication and printing costs relating to two of Allegro's new products.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased by $479,790 or approximately 50% from $960,193
in 1994 to $1,439,983 in 1995 and increased as a percentage of net sales from
approximately 95% to approximately 102%. Bad debt expense increased from
approximately $39,000 in 1994 to approximately $199,000 in 1995, or
approximately 409%, primarily as a result of Allegro's provision for its
receivable from Media Depot, Inc. and ABCO Distributing Inc. Total selling
expenses increased 67% from approximately $292,000 in 1994 to approximately
$488,000 in 1995, primarily as a result of increased trade advertising as well
as increased co-operative advertising requirements with Allegro's retail
vendors, and an increase of approximately $70,000 in commissions in 1995 from
1994 levels due to increased sales and use of commissioned based sales programs
implemented in 1995. Total salaries and wages increased approximately 37% from
approximately $388,000 in 1994 to approximately $531,000 in 1995 representing
the costs associated with additional staffing required to support the sales
expansion plans of Allegro and other corporate staffing. In 1995, Allegro also
experienced increased costs associated with external accounting services and a
financial consulting agreement with MS Farrell, Allegro's initial public
offering underwriter. These increases totaled approximately $68,100,
representing approximately 14% of the increase in the selling, general and
administrative expenses.
 
     Product Development.  Product development expenses remained at
approximately the same levels year-over-year, decreasing slightly from
approximately $298,800 in 1994 to approximately $295,900 in 1995, or
approximately 1%. As a percentage of net sales, product development decreased
from approximately 30% in
 
                                       84
<PAGE>   93
 
1994 to approximately 21% in 1995. Allegro was able to develop eleven new
products in 1995 versus six in 1994 for approximately the same costs. Allegro
believes that development expenses will increase in dollar amount in the future
as Allegro expands its development activities, although Allegro's long-term goal
is to continue to reduce product development costs as a percentage of sales. All
development costs have been expensed in the period incurred.
 
     Interest (Income) Expense (Net).  As a result of the August 1995 sale of
Bridge Units, net interest expense increased $34,934 in 1995. Allegro had no
interest bearing liabilities in 1994.
 
     Extraordinary Item.  In conjunction with Allegro's sale of Bridge Units in
August 1995, and the subsequent repayment of the notes and issuance of Allegro
Common Stock upon the completion of Allegro's initial public offering, Allegro
experienced deemed interest and financing costs of $990,928 associated with the
notes in 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Allegro historically has been unable to generate sufficient cash flow to
fund operations. Working capital deficiencies had been funded principally
through private placements of securities until Allegro's initial public offering
("IPO"), completed in December 1995, and the exercise by the underwriter of its
over-allotment option on January 23, 1996. Allegro through its IPO raised net
funds of $4,156,411 ($2,906,411 after retiring debt) and $464,907 from the
exercise of the over-allotment option. As a result of the Merger Agreement with
SPC, Allegro obtained a loan facility of $1,000,000. As of September 30, 1996
Allegro had working capital of $351,035, including cash and cash equivalents of
$990,516 and a note receivable of $200,000. Management believes that Allegro has
working capital sufficient for Allegro's current operations for at least the
next twelve months. Allegro has no bank or other credit facility other than the
loan facility from SPC and there can be no assurances that Allegro will be able
to obtain such financing on favorable terms, if at all, or that such financing
will be on terms acceptable to Allegro. See Note 6 to the Condensed Consolidated
Financial Statements.
 
     Allegro's operating activities for the first nine months of 1996 used cash
of $1,783,155, primarily related to costs associated with and loans made to
Serif as part of Allegro's acquisition of Serif, an increase in accounts
receivable and inventories associated with higher net revenues and a reduction
of trade accounts payable. Allegro intends to continue to utilize its working
capital in 1996 for product development, marketing and advertising, to finance
the higher level of inventory and accounts receivable necessary to support the
anticipated continued increase in sales, for capital expenditures, including the
purchase of computer equipment, and for internal and external software
development. However, Allegro's working capital requirements may change
depending upon numerous factors, including, without limitation, the need to
finance the licensing or acquisition of third party software as well as
increased inventory and accounts receivable arising from the sale and shipment
of new products.
 
     Allegro estimates its consolidated tax net operating loss carryforwards to
be approximately $10.2 million at September 30, 1996. Allegro expects that after
giving effect to the Merger, an "ownership change" will be deemed to have
occurred under Section 382 of the Code and the regulations thereunder with
respect to it, and that as a result thereof the use by the Combined Company of
the net operating loss carryforwards of Allegro will be limited.
 
     From December 1993 through May 1995, Barry A. Cinnamon and Richard Bergman,
Allegro's former Vice President--Product Development, placed an aggregate of
542,500 shares of Allegro Common Stock in escrow pending Allegro's attainment of
certain minimum net revenue or Allegro Common Stock price per share thresholds.
Five hundred and thirty-one thousand (531,000) of these shares have been
released from escrow (500,000 shares to Barry A. Cinnamon and 31,000 to Richard
Bergman) by the Allegro Board, with the consent of MS Farrell and the remaining
11,500 of these shares have been surrendered for cancellation. In connection
therewith, Allegro has recognized compensation expense of approximately
$2,773,180 in the nine-month period ended September 30, 1996.
 
     Except for historical information contained herein, the matters set forth
herein are forward-looking statements that involve certain risks and
uncertainties that could cause actual results to differ materially from
 
                                       85
<PAGE>   94
 
those in the forward-looking statements. Potential risks and uncertainties
include, among other things, such factors as the level of business and consumer
spending for computer software, the amount of sales of Allegro's products, the
competitive environment within the computer software industry, the ability of
Allegro to integrate the Serif operations, the level and costs incurred in
connection with Allegro's product development efforts and the financial strength
of the retail industry.
 
SEASONALITY
 
     The computer software market is characterized by significant seasonal
swings in demand, which typically peak in the fourth quarter of each year. The
seasonal pattern is due primarily to the increased demand for software during
the year-end holiday buying season. Allegro expects its net sales and operating
results to continue to reflect this seasonality. Allegro's revenues may also
experience substantial variations as a result of a number of factors, such as
consumer and business preferences and introduction of competing titles by
competitors, as well as limited time promotional pricing offers. There can be no
assurance that Allegro will achieve consistent growth or profitability on a
quarterly or annual basis.
 
INFLATION
 
     Allegro believes that inflation has generally not had a material impact on
its operations.
 
                          ALLEGRO CERTAIN TRANSACTIONS
 
     In May 1995, MS Farrell, the underwriter of Allegro's IPO, loaned $100,000
to Allegro. This loan was evidenced by a promissory note in the principal amount
of $100,000, bearing interest at a rate equal to fourteen percent (14%) per
annum, maturing on the earlier of (i) December 25, 1995 or (ii) the consummation
of a subsequent offering of securities other than similar notes. This note was
secured by Allegro's accounts receivable and was repaid from the proceeds of the
Bridge Notes. In June through August 1995, MS Farrell acted as Placement Agent
with respect to an aggregate $459,000 principal amount of additional 14%
Promissory Notes issued by Allegro to other persons. MS Farrell did not receive
any compensation in connection therewith.
 
     Allegro and MS Farrell have in the past entered into certain engagement
agreements. Pursuant to an engagement agreement dated December 12, 1995, as
amended, between Allegro and MS Farrell, Allegro agreed (a) to use MS Farrell as
its exclusive investment banker for a five-year period, (b) to pay monthly fees
to MS Farrell of $2,500 until December 1998, and (c) to pay to MS Farrell a fee
of 2% of the greater of the maximum commitment under or the maximum amount
actually borrowed by Allegro pursuant to a conventional line of credit extended
to Allegro by a bank or other short-term lender introduced to Allegro by MS
Farrell. Allegro has the right to terminate the above-described obligations
under this engagement agreement upon the payment of $250,000 in cash or in
shares of Allegro Common Stock valued at market, at the option of Allegro.
 
     MS Farrell acted as placement agent on behalf of Allegro in selling an
aggregate of 1,115,250 shares of Class A Convertible Preferred Stock of Allegro
in June 1994 and an additional 75,000 shares of Class A Convertible Preferred
Stock in November 1994 for aggregate gross proceeds of $1,190,250. In
consideration for its services in connection therewith, MS Farrell received a
10% commission on the gross proceeds of such offering, a 3% non-accountable
expense allowance, a warrant which became exercisable for an aggregate of
302,354 shares of Allegro Common Stock, which MS Farrell has exercised in full
for nominal consideration, and certain other consideration. MS Farrell also
acted as placement agent on behalf of Allegro in selling an aggregate of
$1,250,000 principal amount of the Bridge Units in August 1995. In connection
for its services in connection therewith, MS Farrell received a 10% commission
on the gross proceeds of such offering and a 3% non-accountable expense
allowance. MS Farrell's $100,000 loan to Allegro was also repaid in connection
therewith. MS Farrell acted as managing underwriter of Allegro's IPO. In
connection therewith, MS Farrell received a 10% underwriting discount, a 3%
non-accountable expense allowance and an option to purchase 103,300 shares of
Allegro Common Stock at an exercise price of $6.15 per share until August 20,
2002.

     Barry A. Cinnamon and Richard Bergman placed into escrow an aggregate of
542,500 shares of Allegro Common Stock of Allegro (the "Escrow Shares"), of
which 500,000 shares were placed in escrow by Barry A. Cinnamon and 42,500 of
which shares were placed in escrow by Richard Bergman. In April 1996, upon the
execution and delivery by Allegro of a letter of intent to acquire all of the
issued and outstanding capital stock of Serif, Inc. and Serif (Europe) Limited,
217,000 shares of Allegro Common Stock then held in escrow pursuant to the
above-described arrangements were released from escrow and delivered to the
above-named stockholders, 200,000 of which shares were delivered to Barry A.
Cinnamon and 17,000 of which shares were delivered to Richard Bergman (the
"April 1996 Escrow Release"). In September 1996, 314,000 of the remaining shares
of Allegro Common Stock then held in escrow pursuant to the above-described
arrangements were released from escrow and delivered to Barry A. Cinnamon
(300,000 shares) and Richard Bergman (14,000 shares) (the "September 1996 Escrow
Release"; and together with the April 1996 Escrow Release, the "Escrow
Release"). Presently, no shares remain in escrow and all of the arrangements
relating to the Escrow Shares have been terminated. In April 1996, the Company
incurred an additional compensation expense of $637,980 in connection with the
April 1996 Escrow Release, and in September 1996 the Company incurred an
additional compensation expense of approximately $2,135,200 in connection with
the September 1996 Escrow Release.
 
     In April 1996, Barry A. Cinnamon sold 44,000 shares of Allegro Common Stock
to MS Farrell for a price equal to $2.00 per share, and in August 1996, Barry A.
Cinnamon sold 42,946 shares of Allegro Common Stock to MS Farrell for a price
equal to $6.00 per share.
 
     In July 1996, Allegro acquired all of the issued and outstanding shares of
capital stock of Serif Inc. and Serif (Europe) Limited. Pursuant to the terms of
the acquisition agreements, Allegro issued to the stockholders thereof an
aggregate of 1,000,000 shares of Allegro Common Stock and agreed to nominate
Gwyn Jones or his designee to the Board of Directors of Allegro. In addition,
Barry A. Cinnamon, Mr. Jones, and the other former stockholders of the Serif
companies entered into a Stockholders Agreement pursuant to which each party
agreed to vote their shares of Allegro Common Stock in favor of the election as
directors of the nominees for directors nominated by the Allegro Board and in
favor of the election as a director of Mr. Jones or his designee. Pursuant to
the terms of Allegro's acquisition of Serif, Allegro's subsidiary Serif (Europe)
Limited entered into a three-year employment agreement with Gwyn Jones, the
founder and largest stockholder of Serif, and Allegro elected Gwyn Jones as a
director in Class II. In October 1996, Mr. Jones resigned as an officer,
director and employee of Allegro and Serif pursuant to agreements under which
Mr. Jones received or is to receive the base salary payable under his employment
agreement and certain other consideration, including the elimination of the
prohibition on Mr. Jones selling the 469,804 shares of Allegro Common Stock
which Mr. Jones received pursuant to the acquisition and the substitution, in
lieu thereof, of a restriction on such sales allowing him to sell no more than
thirty percent (30%) of the average daily trading volume of Allegro Common Stock
in any week and certain other restrictions. Upon his resignation as a director
of Allegro, Mr. Jones designated Norman Alexander as his nominee to the Allegro
Board. Mr. Alexander has not yet agreed to serve as a director of Allegro.
 
     In October 1996, the Board of Directors of Allegro determined to increase
Barry A. Cinnamon's salary to $150,000 per year and to increase Mark E.
Leininger's salary to $145,000 per year, in each case effective at the Effective
Time, as well as to pay a bonus of $25,000 to each of Mr. Cinnamon and Mr.
Leininger, payable following the first profitable fiscal quarter of the Combined
Company.
 
     All future transactions between the Company and its officers, directors and
5% shareholders will be on terms no less favorable than could be obtained from
independent, third parties and will be approved by a majority of the
independent, disinterested directors of the Company.
 
COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT
 
     Section 16(a) of the Exchange Act requires Allegro's executive officers,
directors and persons who own more than ten percent of a registered class of the
Company's equity securities ("Reporting Persons") to file reports of ownership
and changes in ownership on Forms 3, 4, and 5 with the Securities and Exchange
Commission (the "SEC") and the National Association of Securities Dealers (the
"NASD"). These
 
                                       87
<PAGE>   96
 
Reporting Persons are required by SEC regulation to furnish Allegro with copies
of all Forms 3, 4 and 5 they file with the SEC and NASD. Based solely on
Allegro's review of the copies of the forms it has received, Allegro believes
that all Reporting Persons complied on a timely basis with all filing
requirements applicable to them with respect to transactions during fiscal year
1995, except that each of Allegro's executive officers and directors filed their
initial reports on Form 3 several days late.

SPC BUSINESS
 
GENERAL
 
     Software Publishing Corporation ("SPC") is an international supplier of
business productivity software, dedicated to delivering personal computing
software with functionality and ease of use both on the desktop and
electronically over the Intranet/Internet. SPC develops and markets software
products that enable business professionals to access, understand and
communicate information visually. SPC currently offers products that operate on
the Windows, Windows 95, and DOS operating systems for IBM personal computers
and compatibles. SPC was incorporated in California in 1980 and reincorporated
in Delaware in 1991. SPC's principal offices are located at 111 North Market
Street, San Jose, California 95113, telephone (408) 537-3000.
 
     See "SPC Management's Discussion and Analysis of Financial Condition and
Results of Operations" for additional information concerning SPC's business and
financial condition.
 
     SPC's principal product families are the ASAP line of Intelligent
Formatting products and the Harvard 1 line of graphical information presentation
products. ASAP, the first product based upon the Intelligent Formatting
technology acquired as a result of SPC's purchase of Digital Paper, Inc. in
March of 1995, was introduced late in the fourth quarter of fiscal 1995. In
fiscal 1996, SPC introduced three new products including ASAP WordPower, ASAP
WebShow, and ASAP WebShow Presentation Kit. In the fourth quarter, SPC released
a presentation suite of products called the Harvard Graphics Presenter's Pack,
consisting of Harvard Graphics, Harvard ChartXL, Harvard Spotlight, and Flamingo
Plus (distributed under license from a third party). Additionally, SPC created
two internet plug-ins during fiscal 1996, ASAP WebShow for Netscape Navigator
and an ActiveX version of ASAP WebShow for the new Microsoft Internet Explorer
3.0. SPC also continues to offer word processing and other business productivity
software products.
 
     The majority of SPC's products are sold through corporate reseller and
computer software retail channels. The corporate sales are comprised of both
individual product sales as well as volume sales. Most sales to the retail
channel are made on a two-step basis with the initial sales being made to
distributors and then to the actual retail chains. SPC also distributes its
products through original equipment manufacturers ("OEMs") on a bundled or
value-added basis.
 
     Reseller computer stores of SPC products include major national dealers
such as Egghead Discount Software, Computer City, CompUSA and Staples. Major
corporate resellers of SPC products include Stream International, Inc., Softmart
Inc., and Software Spectrum, Inc. SPC's major distributor is Ingram Micro, Inc.
Sales to resellers and distributors comprised approximately 80%, 84%, and 75% of
net revenues in fiscal 1994, 1995, and 1996, respectively. Upgrades to SPC's
products are sold through resellers and distributors, as well as directly by
SPC, to end users. Late in fiscal 1996, SPC began to shift its target market,
with a focus toward the SOHO market and medium size corporations, with changes
towards channels of distribution that are most closely aligned with such
markets.
 
RECENT DEVELOPMENTS
 
     Products.  In September 1996, SPC announced its second major product based
upon Intelligent Formatting, ActiveOffice. ActiveOffice is a companion product
to Microsoft Office that is designed to give users of MS Word, MS Excel, MS
PowerPoint and MS Exchange a quick and easy way to convert plain text and
numbers into visual graphics.

     Restructuring.  On August 13, 1996, SPC announced third fiscal quarter 1996
results and a strategic repositioning charge in order to align its business
operations with its continuing shift to products based upon its Intelligent
Formatting technology and away from its Harvard Graphics line of products. As a
result, the Company announced that it would reduce its worldwide headcount by
approximately 42% over the next two months and take a net charge to fourth
quarter results of between $2.0 and $3.0 million. The Company anticipates that
it will have approximately sixty-five employees at December 31, 1996. The actual
restructuring charge taken as of September 30, 1996 was $1.1 million.
 
     Changes in Executive Officers.  On August 13, 1996, SPC also announced the
resignation of Irfan Salim, president and chief executive officer. The Board of
Directors established an Office of the President reporting to the Chairman of
the Board, Fred Gibbons, and an executive search was initiated for a new chief
executive officer. The Office of the President consists of Daniel Fraisl, Vice
President of Research and Development; Miriam Frazer, Vice President-Finance and
Chief Financial Officer; and Joseph Szczepaniak, Vice President of Sales and
Marketing.
 
SPC BUSINESS STRATEGY
 
     SPC's strategic objective is to become a leading supplier of easy-to-use
integrated visual communications products that increase the effectiveness and
power of the messages they deliver, whether a message takes the form of a
document, a report, a presentation or electronic mail. To achieve its strategic
objective, SPC intends to build upon the Intelligent Formatting technology base
by adding new products and new features to existing products utilizing the
Intelligent Formatting technology. SPC also intends to continue to support new
computing environments as they emerge, and intends to broaden the categories of
products it offers within its target markets.
 
     Many current graphical presentation software applications and
first-generation Internet publishing tools have been geared toward computer
specialists, corporate MIS departments, computer consultants and other
technically knowledgeable users. The Company believes that there is a large
market opportunity for software that enables non-specialists to easily and
quickly produce the high-quality, graphically rich documents that many audiences
have come to expect. SPC acquired its Intelligent Formatting technology through
the acquisition of Digital Paper, Inc. in March, 1995, to enable SPC to develop
products for this market opportunity.
 
     SPC's Intelligent Formatting technology is designed to allow users who are
not computer specialists to create effective, well-designed visual information
using simple high level commands. With Intelligent Formatting, the user is able
to easily manipulate graphic design factors such as layout, design, and color,
and the program automatically correlates these factors to create an effective
and visually pleasing design. Moreover, the automated correlation of these
design factors enables the user to make changes, even at the last minute, and to
test "what if" scenarios with the confidence that the change will not create
unexpected ripple effects requiring many more changes before a satisfactory
document is produced. In contrast, many experienced users of traditional
graphical presentation programs have learned to be very cautious in making
changes at the last minute because of ripple effects in which one change
necessitates many other changes to restore the visual integrity of the document.
For example, adding two lines to the end of a slide in a traditional
presentation software program could cause text to flow off the end of the slide.
However, with Intelligent Formatting, the text on the slide would be
automatically rearranged, and the font sizes changed, to maintain a visually
pleasing design.
 
     SPC believes its Intelligent Formatting technology is ideally suited for
use on distributed systems such as the Internet because it requires only
unformatted text, along with a small amount of additional information, to be
stored in a file and transmitted across a network. All graphical formatting of
the document is derived on-the-fly by the Intelligent Formatting engine as the
object is viewed, substituting relatively abundant local computing power for
relatively scarce network transmission bandwidth. In addition, the technology's
component-based architecture is compact, efficient and highly portable across

MARKETING
 
     SPC markets software solutions designed to aid the user's ability to
communicate key ideas, thoughts, trends and relationships through a variety of
computer products. SPC's Harvard Graphics, Harvard ChartXL, Harvard Spotlight
and other products are targeted toward the business professional who uses
application software to increase productivity, yet demands that the program
require a minimum amount of training time. SPC's ASAP, ASAP WordPower and ASAP
WebShow are targeted toward the SOHO market and medium-sized corporations with
application to the Internet and Intranet. The ASAP product line, based upon
Intelligent Formatting technology, automatically designs and formats
information, thereby helping the user create well-designed visual information.
In addition, this technology's component-based architecture is compact,
efficient and portable to other platforms.
 
     SPC's advertising programs for its product lines are designed to increase
corporate and product brand awareness. SPC's advertising targets new customers,
its installed customer base, and, with competitive upgrade promotions, its
competitors' customers. SPC advertises primarily through business trade
periodicals, direct mailings and participation at trade shows. SPC also promotes
its products through in-house training and direct mail as well as offering
volume purchase discounts and site licenses. SPC implements promotions to
support distributors' and resellers' sales efforts, including advertising,
rebates, training and price promotions, and engages in joint promotional
activities with personal computer, peripheral and other manufacturers.
 
     Gross margins have been, and will continue to be, adversely affected by
competitive pricing pressure throughout the industry as a whole, including OEM
pricing, direct mail, competitive upgrade pricing and alternative licensing
arrangements. SPC has experienced this competitive pricing pressure in respect
to all of its current product offerings.
 
     SPC translates many of its products, including documentation, software, and
promotional materials, for international markets. Advertising and promotional
programs are customized for local markets where necessary.
 
     In June 1996, SPC entered into a non-exclusive licensing and joint
development agreement with Oracle to embed Intelligent Formatting technology in
the Oracle InterOffice Product Line. Under the agreement, SPC's Intelligent
Formatting engine is being ported to Java for use in the Oracle InterOffice
product line. Intelligent Formatting technology is intended to enhance the
Oracle InterOffice product offerings in the area of visual communications. The
collaborative services offered by Oracle InterOffice--messaging, directory
services, calendar/scheduling, document management and workflow--are designed to
enable users to productively share, exchange and manage information within their
group, across the enterprise and beyond. Intelligent Formatting technology will
complement these services by adding rich visual content to the range of the
Oracle InterOffice applications. Under the terms of this agreement, Oracle paid
SPC a development fee, and a one-time license fee, payable in installments. The
development fee and license fee do not have a
 
                                       98
<PAGE>   107
 
material financial benefit to SPC. It is possible that SPC will receive
additional sales and marketing benefits through cross-selling of related
products to Oracle's installed customer base.
 
     In addition, in June 1996, Oracle Corporation purchased a worldwide
end-user site license for SPC's award-winning ASAP WordPower visual
communications software. Under the terms of the agreement, SPC granted Oracle
and its subsidiaries a license for the desktop, network and mobile use of ASAP
WordPower.
 
SALES AND DISTRIBUTION
 
     SPC's primary channel of worldwide distribution is through software
distributors and resellers. SPC's North American sales organization is segmented
into three groups: channel, corporate sales and OEMs. The channel group assists
distributors and resellers in selling, promoting and merchandising SPC's
products. This group is responsible for sales to distributors and resellers, and
also provides training to the resellers. The corporate sales group works closely
with corporate and government evaluators of software for information management
centers to meet the software demands of their personal computer users. Programs
include in-house corporate training seminars, assistance with system
implementation, product updates, and the integration of SPC's products with
existing customer systems. Corporate and government sales are fulfilled
principally through resellers and distributors. SPC also offers site licenses
and volume purchase discounts to its corporate customers. The OEM group is
responsible for sales to hardware and software original equipment manufacturers.
 
     Sales to resellers are made directly by SPC, as well as by distributors,
who purchase directly from SPC at volume discounts. Principal distributors for
fiscal 1994 were Ingram Micro, Inc., and Merisel Computer Products, Inc., which
accounted for approximately 22% and 8% of total net revenues, respectively. In
fiscal 1995 and fiscal 1996, SPC's principal distributor worldwide was Ingram
Micro, Inc., which accounted for approximately 31% and 19% of total net sales,
respectively. SPC's principal direct resellers were Egghead Discount Software,
Inc., and Computer 2000, which each accounted for less that 10% of net revenues
in fiscal years 1994, 1995 and 1996.
 
     International sales (sales outside of North America) are made directly by
SPC and through SPC's foreign sales subsidiaries to distributors and resellers.
In fiscal 1994, 1995 and 1996, international sales accounted for approximately
33%, 36% and 34% respectively, of SPC's total net revenues. SPC maintains sales
offices in the United Kingdom, Germany and Australia. Fiscal 1996 international
net revenues decreased approximately 61% compared to fiscal 1995 international
net revenues.
 
     International sales include localized versions of selected products, as
well as the English language versions of SPC's products throughout Europe, Latin
America, and the Asia/Pacific region. Localized versions include German, French,
Spanish, Italian, Portuguese and Dutch. SPC invoiced approximately 29% of its
worldwide sales in fiscal 1996 in foreign currencies, and expects this practice
to continue. Accordingly, SPC is subject to exchange rate fluctuations.
 
     SPC has a general return policy for its North American resellers and
distributors whereby they may return any products previously purchased from SPC,
provided that the aggregate purchase price for such returned products does not
exceed ten percent of the reseller's or distributor's net purchases for the
prior quarter. In addition to this return allowance, North American distributors
and resellers may generally exchange any discontinued products within ninety
days of notification of discontinuation for products of equal or greater value.
For international distributors and resellers, the general return policy is the
same as for North American resellers and distributors, except that returns with
respect to sales in a quarter must be completed within the first month of the
subsequent quarter. For international distributors and resellers, the policy for
the exchange of obsolete products generally allows returns within thirty days
after the announcement of a product's obsolescence, provided that the product
was shipped within thirty days prior to the announcement. However, to maintain
good customer relations, SPC may accept returns in excess of those allowed under
its general policy.
 
                                       99
<PAGE>   108
 
     SPC typically ships products within several days after receipt of orders,
which is customary in the personal computer applications software business.
Accordingly, SPC does not believe that backlog is a meaningful indicator of
future business.
 
CUSTOMER SUPPORT
 
     SPC provides free technical support through third parties for a period of
thirty days from the first call to technical support from the customer. SPC
reserves for the cost of this support at the time of sale. After this initial
period, technical support is available for purchase from third parties under a
variety of value-added support programs.
 
PRODUCT DEVELOPMENT
 
     The personal computer software industry is characterized by rapid
technological change which requires a continuing high level of expenditures for
the enhancement of existing products and the development of new software
products. SPC's current product development activities include enhancing and
updating its present software packages and designing new products.
 
     Since acquiring Digital Paper Inc. and its Intelligent Formatting
technology in March 1995, SPC's mission has been to become a technology leader
by creating products that enable users to efficiently use both the desktop
computer environment and emerging computer and communication technologies
including the Internet, electronic mail, remote conferencing, and personal
information devices.
 
     Since September 1995, SPC has introduced three Intelligent Formatting-based
products for desktop and Internet presentations. For the Internet, SPC has
developed versions of its ASAP WebShow product that are included as plug-ins
(complementary products) for both Netscape Navigator and Microsoft Internet
Explorer products. The latest Intelligent Formatting product, ActiveOffice (a
companion to Microsoft Office), is currently in Beta test and is expected to
ship to customers in early 1997.
 
     The Intelligent Formatting technology is based on an automatic graphical
layout engine with a relatively small memory footprint, low communication
bandwidth requirements and device/media independence. Intelligent Formatting
captures the visual idioms used by graphic designers in both print and
electronic media in the form of intelligent visual objects. This technology has
been widely recognized for its power and ease-of-use compared to traditional
software products.
 
     SPC is currently focusing research and development resources on continuing
to develop the Intelligent Formatting technology into a range of products
targeted at both the desktop and Intranet/Internet markets. SPC believes that
its Intelligent Formatting architecture provides a fast, powerful and flexible
environment that advances the state-of-the-art in graphical algorithms and
protocols, and that Intelligent Formatting provides a technology foundation for
the ongoing development of a wide range of products for the desktop, Internet,
and corporate Intranet markets. There can be no assurance, however, that SPC
will be able to successfully develop and commercialize Intelligent Formatting
products, or any other new products, or that any such products will be
commercially successful.
 
COMPETITION
 
     The market for personal computer applications software is highly
competitive and has been subject to rapid development and change. Some of SPC's
competitors sell "bundles" or "suites" of products which include products that
directly compete with SPC's products and which are bundled with other software
programs by the same or multiple competitors. These suite products are sold at
an all-inclusive price. Additionally, application software is increasingly being
bundled and pre-loaded into new computers. The price for a stand-alone or
pre-loaded bundle or suite of software is typically significantly less than
separately purchased applications, and many end users are likely to prefer the
bundle or suite over a more expensive combination of other individually
purchased applications, even if the latter applications offer superior
performance or features. These factors have resulted in significant downward
pressures on average selling prices for SPC's products.
 
                                       100
<PAGE>   109
 
     SPC's primary competitor is Microsoft Corporation. The dominant position of
Microsoft in the personal computer operating system and application program
marketplace provides it with competitive advantages, including the ability to
determine the direction of future operation systems and to leverage its strength
in one or more product areas to achieve a dominant position in new markets. This
position may enable Microsoft to increase its market position even with respect
to products having performance and features superior to those offered by
Microsoft. Microsoft's ability to offer productivity software, to bundle
software, to provide incentives to customers to purchase certain products in
order to obtain favorable sales terms or necessary compatibility or information
with respect to other products, and to pre-load such bundled software on new
computers may significantly inhibit SPC's ability to maintain its business. In
addition, as Microsoft creates new operating systems and applications, there can
be no assurance that SPC will be able to ensure that its products will be
compatible with those of Microsoft.
 
     In addition, SPC could face additional competition from other independent
software companies not currently in the personal computer applications software
market, but which may decide to enter this market in the future.
 
     SPC believes that the principal competitive factors in its market include
pricing (which includes individual product pricing, standard and competitive
upgrade pricing, licensing and volume discounting), product functionality and
ease of use, inclusion in suites of office products, brand name recognition,
availability and quality of training and support, quality of documentation,
operating platform availability and integration. SPC's ability to compete is
contingent on its continued enhancement of its existing products, on its ability
to correctly identify and enter new markets, and to its ability to develop new
products adapted to changes in computer hardware and operating systems. SPC
believes that competition is likely to continue to intensify in the future and
that new product introductions, further price reductions, strategic alliances
and other actions by competitors could materially and adversely affect SPC's
competitive position.
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
     SPC's success depends significantly upon its proprietary technology. SPC
currently relies on a combination of copyright and trademark laws, trade
secrets, confidentiality procedures and contractual provisions and other written
materials under trade secret, patent and copyright laws, which afford only
limited protection. SPC has registered and applied for registration for certain
service marks and trademarks, and will continue to evaluate the registration of
additional service marks and trademarks as appropriate. Despite SPC's efforts to
protect its proprietary rights, unauthorized parties may attempt to copy aspects
of SPC's products or services or to obtain and use information that SPC regards
as proprietary. In addition, the laws of some foreign countries do not protect
proprietary rights to as great an extent as do the laws of the United States.
Monitoring and identifying unauthorized use of such broadly disseminated
products as personal computer software is difficult. SPC expects software piracy
to be a continuing problem for the software industry. SPC relies principally
upon software engineering and marketing skills to protect its market position,
rather than solely on copyright or trademark or trade secret protection.
 
     SPC currently has two patent applications pending, one related to its
Intelligent Formatting technology and the other to technology contained in its
Harvard Spotlight product. There can be no assurance that any pending
application will be approved, that if issued, any such patent will not be
challenged, and that if challenged, any such patent will not be invalidated.
There can be no assurance that any issued patent will provide SPC with any
competitive advantages or will not be challenged by third parties, any of which
may have a material adverse effect on SPC. To the best of its knowledge, SPC
retains exclusive ownership rights to all software, both developed and
commercially distributed by SPC, except for those components of the software
that SPC licenses from third parties. All such software offered by SPC is
licensed and provided in object code pursuant to either shrink-wrap license
agreements or executed license agreements which contain restrictions on
disclosure and transferability.
 
     In addition, SPC has from time to time licensed third parties to use,
modify, reproduce, sublicense, distribute and market certain of SPC's software
products or portions of its software products. Such licensed
 
                                       101
<PAGE>   110
 
software is provided in object code and, in certain limited circumstances,
source code, pursuant to agreements which contain restrictions on disclosure and
transferability.
 
     Litigation may be necessary to protect SPC's proprietary technology. Any
such litigation may be time-consuming and costly. There can be no assurance that
SPC's means of protecting its proprietary rights will be adequate or that SPC's
competitors will not independently develop similar technology or duplicate SPC's
products or services or design around patents or other intellectual property
rights of SPC. There have been substantial amounts of litigation in the software
industry regarding intellectual property rights. There can be no assurance that
the patents of others will not have a material adverse effect on SPC's ability
to do business.
 
     Because the software development industry is characterized by rapid
technological change, SPC believes that factors such as the technological and
creative skills of its personnel, new product developments, frequent product
enhancements, name recognition and reliable product maintenance are as important
to establishing and maintaining a technology leadership position as the various
legal protections of its technology.
 
     Certain technology used in SPC's products is licensed on a perpetual, fully
paid, non-royalty bearing basis from third parties. If any event occurred that
rendered technology licensed from a third party and incorporated in SPC's
products unavailable to SPC, or if the technology is not appropriately supported
and enhanced by the licensor, SPC would be forced to expend financial and
development resources to replace that technology. Such expenditures could
materially adversely affect SPC's business, financial condition and results of
operations.
 
     Harvard Graphics, Harvard ChartXL, Harvard Spotlight, Harvard, and the SPC
logo are registered trademarks of SPC in the United States and certain foreign
jurisdictions. Intelligent Formatting, ASAP, ASAP WordPower, ASAP WebShow and
ActiveOffice are trademarks of SPC.
 
     SPC is not aware that any of its products infringes the proprietary rights
of third parties. There can be no assurance, however, that third parties will
not claim such infringement by SPC or its licensors with respect to current or
future products. SPC expects that software product developers will increasingly
be subject to such claims as the number of products and competitors in SPC's
industry segment grows and the functionality of products in different industry
segments overlaps. Any such claims, with or without merit, could be time-
consuming, result in costly litigation, cause product shipment delays or might
require SPC to enter into royalty or licensing agreements. Such royalty or
licensing agreements, if required, may not be available on terms acceptable to
SPC.
 
PRODUCTION
 
     SPC's product development staff establishes the final product testing
criteria and produces the master diskettes, CD-ROMs and user manuals for its
proprietary software, as part of its product development activities. Duplication
of the master diskettes, CD-ROMs and user manuals, production of the packaging
material and assembly of the disk and/or CD-ROM and manual into the final
package are performed by third parties to SPC's specifications. After packaging,
the products are shipped by third parties.
 
     To date, SPC has not experienced any material difficulties or delays in
production of its software products and related documentation. Media for SPC's
software primarily consists of CD-ROMs and 3 1/2-inch micro-diskettes, which are
purchased by subcontractors of the Company and are available from multiple
sources of supply.
 
EMPLOYEES
 
     As of September 30, 1996, SPC had 72 full-time regular and non-regular
employees, of whom 23 were in product enhancement and development, 28 were in
marketing, sales and customer support, 3 were in production and 18 were in
general and administrative functions. Of the total, 63 employees were located in
North America and 9 internationally.
 
     None of SPC's employees are subject to a collective bargaining agreement,
and SPC has never experienced a significant work stoppage. SPC believes that its
employee relations are good and that its future
 
                                       102
<PAGE>   111
 
success will depend, in part, in its ability to continue to attract and retain
highly skilled technical, sales, marketing and management personnel.
 
FACILITIES
 
     On January 2, 1996, the Company relocated its corporate headquarters from
Santa Clara, California to 111 North Market Street, in downtown San Jose,
California. The Company's North American corporate executive, administrative,
sales, marketing and product development and support staff are located at these
facilities. Pursuant to the lease agreement for these facilities, the Company
leased approximately 36,000 square feet of office space for an annual rent of
approximately $525,000, effective January 1996 and expiring in December 2000.
This lease includes two options to extend the lease, each for an additional two
year term and an option to terminate a portion or the entire lease any time
after December 1998.
 
     As of October 1, 1996, in conjunction with the Company's reduction in
force, the Company surrendered a portion of the original leased premises
(approximately 12,870 square feet of space), paid a termination fee of $55,000
to the landlord, and as a result, the annual rent was reduced to $333,104.
 
     In the second quarter of fiscal 1996, the Company entered into a sublease
with Macromedia, Inc., pursuant to which the Company subleased to Macromedia a
portion of the Company's leased facilities located in Bracknell, United Kingdom.
 
LEGAL PROCEEDINGS AND CLAIMS
 
     In June 1994, SPC sold its Superbase product line to Computer Concepts
Corporation ("CCC") for 2,031,175 shares of CCC's restricted common stock. As
part of such sale, CCC agreed to issue additional shares to SPC if CCC failed to
register such shares with the SEC for resale by SPC within certain time periods
or, in certain circumstances, if SPC realized less than a specified price upon
such resale. In September 1996, CCC and SPC entered into a binding letter of
intent, pursuant to which CCC agreed to pay SPC $619,420 and issue to SPC
1,064,667 additional shares of CCC common stock as penalties for late
registration. In October 1996, SPC and CCC entered into a definitive settlement
agreement, reflecting the same terms and conditions, including additional
release of claims provisions, and SPC received the foregoing cash and shares. As
of September 30, 1996, SPC had sold 588,195 shares of CCC common stock for a
gain of $0.6 million. As of October 21, 1996, SPC had sold an additional 674,000
shares. It is anticipated that SPC will attempt to sell the remaining CCC
shares, approximately 1.8 million, over the next three fiscal quarters. As of
September 30, 1996, the closing price of the CCC common stock on the Nasdaq/NMS
was $0.59.
 
     SPC is a defendant in certain litigation. Management is of the opinion that
the ultimate outcome of this litigation will not have a material adverse effect
on the future operations or financial condition of SPC.
 
     In 1991, SPC received certain restricted stock upon the sale of a product
line. Subsequent to the sale, SPC and the buyer of the product line entered into
litigation. In fiscal 1994, the litigation was resolved, and SPC received an
arbitration award of $2.6 million, and the restricted stock was sold, resulting
in income of $3.4 million.
 
                  SPC MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

  Net Revenues
 
     Net revenues worldwide significantly declined in fiscal 1996 primarily due
to a steep reduction in revenues from SPC's Harvard Graphics product line for
the DOS and Windows 3.1 operating systems and the lack of offsetting revenues
from sales of Windows 95 application products, resulting from the generally
slower than expected development of the market for applications for the Windows
95 operating system. In addition, SPC experienced substantial competition from
sales by competitors offering suites of products at discounted prices. Revenues
from the ASAP product line, the first product of which was introduced late in
the fourth quarter of fiscal 1995, decreased 50% from fiscal 1995, despite the
introduction of additional ASAP products during fiscal 1996. Harvard Graphics
for Windows revenues decreased 61% from fiscal 1995, despite the fourth quarter
fiscal 1995 release of Harvard Graphics 4.0 for Windows 95. Revenues from the
sales of other Windows-based products, including Harvard ChartXL, Harvard
Spotlight, Harvard Montage and OnFile, declined 57.0% from fiscal 1995, and
revenues from DOS-based products, including Harvard Graphics for DOS, declined
53% from fiscal 1995. In addition to declines in unit sales, average selling
prices have also declined in fiscal 1996 as compared to both fiscal 1995 and
1994. SPC continues to experience a rapid decline in its DOS and Windows market,
as well as intense worldwide competition, particularly in the Windows market.
 
     In fiscal 1996, SPC introduced three new products: ASAP WordPower, ASAP
WebShow, and ASAP WebShow Presentation Kit. In the fourth quarter, SPC released
a presentation suite of products called the Harvard Graphics Presenter's Pack,
consisting of Harvard Graphics, Harvard ChartXL, Harvard Spotlight, and Flamingo
Plus (distributed under license from a third party). Additionally, SPC created
two internet plug-ins during the year: ASAP WebShow for Netscape Navigator and
an ActiveX version of ASAP WebShow for the new Microsoft Internet Explorer 3.0.
Given the recent introduction of these products, SPC is unable to determine the
actual market acceptance of these products. SPC's Internet-based products are
marketed following standard industry practices, which generally entail
distribution of viewing software at no charge and charging for authoring
software.
 
     The Intelligent Formatting technology-based products represented 0%, 7% and
8% of total net revenues in fiscal 1994, 1995 and 1996. The Harvard series of
information presentation products represented 87%, 89% and 70% of total net
revenues in fiscal 1994, 1995 and 1996. Revenues from sales of all products on
the Windows platform accounted for 71%, 86% and 84% of total net revenues in
fiscal 1994, 1995 and 1996. Revenues from upgrade sales represented
approximately 22%, 12% and 19% of total net revenues in fiscal 1994, 1995 and
1996, respectively. Prior to its sale in fiscal 1994, revenues from SPC's
Superbase product line represented 3% of SPC's fiscal 1994 total net revenues.
 
     SPC believes that end users are continuing to migrate from the Windows 3.1
to the Windows 95 platform and expects increased competition, including price
competition, in the Windows 3.1, Windows 95 and Windows NT markets in the
future. A number of SPC's competitors have introduced suites of products which
 
                                       104
<PAGE>   113
 
include products that directly compete with SPC's products and which are bundled
with other office software programs by the same or other competitors. SPC
believes these offerings of product suites have adversely affected SPC's net
revenues, and will continue to adversely affect sales of SPC's products in the
future as the individual products within the suites continue to gain increased
levels of inter-operability and functionality. SPC does not currently offer a
suite of products, although it does offer products that complement competitive
suite products. In order for SPC to increase its net revenues, it must introduce
new marketing strategies and continue to develop and introduce new technologies
and products through strategic alliances, acquisitions or internal development.
Any inability or delay in executing these strategies, difficulties encountered
in introducing new products or marketing programs, or failures of SPC's current
and future products to compete successfully with products offered by other
vendors could adversely affect net revenues and profitability.
 
     SPC believes that its revenues and results of operations for fiscal 1996
were adversely affected by slower than expected customer purchase cycles for
Microsoft Windows 95 application software. The slow purchase rates affected the
upgrade cycle of several of SPC's products. Other factors such as increased
price competition, market uncertainty, the offering of product suites by
competitors and a decline in the Windows 3.1 market have also adversely affected
SPC's revenues and results of operations.
 
  Gross Margins
 
     Cost of revenues decreased from $12.2 million in fiscal 1994 to $7.3
million in fiscal 1995 and $3.0 million in fiscal 1996, representing
approximately 20%, 23% and 23% of net revenues in fiscal 1994, 1995 and 1996,
respectively. Cost of revenues in fiscal 1995 were adversely affected, as
compared to previous fiscal years, by higher excess and obsolete inventory
charges, as well as higher charges for royalty expenses. The fiscal 1996
percentage was relatively unchanged from fiscal 1995 primarily due to reductions
in overhead and lower obsolete inventory charges being offset by direct material
costs per unit declining at a slower rate than the declining average selling
prices per unit. During the past three fiscal years, SPC has experienced lower
overhead and reduced employee-related costs resulting from reorganizations and
reductions in work force, the effects of which, however, have been more than
offset by reduced revenues and fixed costs.
 
     SPC's gross margins and operating income may be affected in particular
periods by the timing of product introductions, promotional pricing and rebate
offers, as well as by return privileges and marketing promotions in connection
with new product introductions and upgrades. These promotions may have a
negative influence on average selling prices and gross margins. Gross margins
have also been, and may continue to be, adversely affected by competitive
pricing strategies in the industry as a whole, including competitive upgrade
pricing, OEM business and alternative licensing arrangements.
 
  Operating Expenses
 
     Total operating expenses, excluding certain non-recurring items, declined
by approximately $44 million, $20 million and $20 million for fiscal years 1994,
1995 and 1996, respectively, compared to the prior year, and represented
approximately 96%, 129% and 158% of net revenues in 1994, 1995 and 1996,
respectively. Operating expenses in fiscal 1994 included restructuring charges
of $7.8 million, including consolidation of facilities, a reduction in work
force and the reversal of prior period restructuring charges of $2.6 million.
Operating expenses in fiscal 1995 included the following non-recurring items: a
charge of $4.8 million for the acquisition of Digital Paper, Inc.; the reversal
of certain legal fee reserves of $0.9 million resulting from reduced legal
exposure; a reversal of prior period restructuring charges of $6.0 million
related to the termination of the lease on SPC's headquarters facility in Santa
Clara, California; and a $5.9 million charge in the fourth quarter for
additional restructuring expense, including a worldwide consolidation of
facilities and reduction in work force. Operating expenses in fiscal 1996
included the following non-recurring items: a charge of $2.1 million to increase
bad debt reserves, which was recorded as a general and administrative expense;
the reversal of $0.7 million of prior period restructuring charges related to
the sub-lease of SPC's international headquarters; and a $1.1 million charge in
the fourth quarter for additional restructuring expense including a reduction in
work force. As a result of the restructuring activity in fiscal 1996, SPC has
increased its restructuring reserve by $1.1 million for the planned reduction of
its work force by approximately 42% by the end of the first quarter of fiscal
1997, as well as excess facilities disposal and product discontinuance. SPC
 
                                       105
<PAGE>   114
 
recorded similar charges in 1994 and 1995, resulting in a 55% and 45% reduction
in work force in those years, respectively. In January 1996, SPC relocated its
corporate headquarters to a smaller facility in downtown San Jose. SPC expects
to continue to reduce its overall cost structure in the future, although there
can be no assurance that it will succeed in its cost reduction efforts.
 
     SPC establishes its targeted expenditure levels based on expected net
revenues. If anticipated orders and shipments do not occur when expected,
expenditure levels could be disproportionately high, and SPC's operating results
could be adversely affected. In the future, SPC's net revenues and operating
results could be adversely affected by these and other factors, such as delays
in new product introductions, the mix of product sales or distribution channels
and customer choices regarding operating systems.
 
     Marketing and Sales.  Marketing and sales expenses decreased from $34.9
million in fiscal 1994 to $21.8 million in fiscal 1995 and $11.1 million in
fiscal 1996 representing approximately 57%, 70% and 86% of net revenues in
fiscal 1994, 1995 and 1996, respectively. This decrease primarily resulted from
lower advertising and promotion expenses and reduced costs due to the
restructuring and related reductions in work force in fiscal 1994, 1995 and
1996, each of which included the closure of several sales offices.
 
     Research and Development.  Research and development expenses decreased from
$17.3 million in fiscal 1994 to $11.9 million in fiscal 1995 and $5.8 million in
fiscal 1996, representing approximately 28%, 38% and 45% of net revenues in
fiscal 1994, 1995 and 1996, respectively. This decrease in absolute dollars was
principally associated with reduced employee and facilities expenses resulting
from restructurings and reductions in work force in the second quarter of fiscal
1994 and fourth quarter of fiscal 1995. SPC believes that it is necessary to
continue to invest in research and development to remain competitive; however,
as a result of the restructuring actions taken by SPC in the second quarter of
fiscal 1994 and fourth quarter of fiscal 1995, research and development expenses
were lower in absolute dollars in fiscal 1996. Specifically, the reorganization
in the second quarter of fiscal 1994 included the cancellation of future
development of the Superbase product line, the consolidation of all research and
development efforts at SPC's headquarters and the closure of other research and
development facilities. The restructuring in the fourth quarter of fiscal 1995
included large reductions in future development on non-Intelligent Formatting
based projects. SPC intends to continue to acquire externally developed
technology, explore strategic alliances and other methods of acquiring or
licensing technology, and invest in internal development projects. Because of
the inherent uncertainties associated with software development projects, there
can be no assurance that SPC's research and development efforts will result in
successful product introductions or increased revenues or profitability.
 
     SPC acquired Digital Paper, Inc., a developer of visual communications
software technology, during the second quarter of fiscal 1995 for approximately
$5.0 million in cash and stock, payable in installments, and up to an additional
$1.5 million in cash upon the achievement of certain unit, revenue and technical
milestones over a three year period. As a result of this acquisition, SPC
recorded a one time charge of $4.8 million in the second quarter of fiscal 1995
for the portion of the transaction related to in-process research and
development. SPC expenses the milestone payments at the time of payment. In the
third quarter of fiscal 1995, SPC paid the first $2.0 million installment
payment, and in the fourth quarter of fiscal 1995, SPC paid the first milestone
payment of $250,000. In the second quarter of fiscal 1996, SPC paid the second
milestone payment of $250,000. In the third quarter of fiscal 1996 SPC paid the
second installment payment of $1.65 million, and in the fourth quarter of fiscal
1996 SPC paid additional milestone payments of $500,000.
 
     General and Administrative.  General and administrative expenses decreased
from $6.8 million in fiscal 1994 to $5.9 million in fiscal 1995 and $5.5 million
in fiscal 1996, representing 11%, 19% and 43% of net revenues for the fiscal
years 1994, 1995 and 1996, respectively. The decline in absolute dollars in
fiscal 1996 was primarily the result of reduced facilities and employee related
expenses resulting from the restructurings and reductions in work force in
fiscal 1994 and 1995 offset by additional bad debt charges in fiscal 1996 of
$2.1 million. Excluding the bad debt charges, general and administrative
expenses decreased to $3.5 million or 27% of net revenues in fiscal 1996.
 
     Provisions for Restructurings and Lease Obligations.  In fiscal years 1994,
1995, and 1996, SPC implemented reorganizations and reduced its work force to
address the changing market dynamics of the application software industry. As a
result of these reorganizations, SPC has closed facilities, centralized all of
 
                                       106
<PAGE>   115
 
its research and development, finance and manufacturing activities, consolidated
its sales and marketing functions and outsourced to third parties its telesales,
support and customer service activities. During the fourth quarter of fiscal
1994, SPC subleased a significant portion of its Santa Clara, California
facility, resulting in the reversal of $2.6 million of reserves associated with
facilities-related restructuring charges initially recorded in the fourth
quarter of fiscal 1992. In the second quarter of fiscal 1994, SPC incurred a
charge of $7.8 million, which included $3.9 million for costs associated with a
reduction in work force and severance costs and $3.9 million for excess
facilities, equipment, professional fees and other. In the fourth quarter of
fiscal 1995, SPC incurred a restructuring charge of $5.9 million, which included
$1.4 million for reduction in worldwide work force and severance costs and $4.5
million for excess facilities and equipment, product discontinuances and other.
In the third quarter of fiscal 1995, SPC reversed $6.0 million in prior period
restructuring charges upon the negotiated termination of the lease on its Santa
Clara, California headquarters facility. In the fourth quarter of fiscal 1996,
SPC incurred a net restructuring charge of $1.1 million, which included $0.2
million for a reduction in worldwide work force and severance costs, and $0.9
million for excess facilities, product discontinuances, and other. In the second
quarter of fiscal 1996, SPC sub-leased a significant portion of its
international headquarters facility, resulting in a reversal of $0.7 million in
prior period restructuring reserves. The charges for excess facilities and
equipment were net of expected sublease income and estimated proceeds on the
sale of excess equipment. The reserves for lease obligations relate to excess
space at SPC's headquarters and certain sales office locations, and include
future rent for excess space and buy-out payments for expected early termination
of certain leases, net of sublease income. The increase in the excess lease
space charges in the fiscal years 1994, 1995 and 1996 above the prior year
levels resulted from further actual or planned reductions in work force in each
year. The reserves were also increased in the second quarter of fiscal 1994 due
to the decline in expected sublease income caused by continuing declines in the
real estate market. (See Note 6 of the Notes to Consolidated Financial
Statements.)
 
  Other Income and Expense
 
     Other income and expense in fiscal 1994 was $8.4 million, which included an
arbitration award of $2.6 million relating to the 1991 sale of an SPC product
line and a $3.4 million gain realized on the sale of restricted stock originally
received in connection with such sale.
 
     Other income and expense increased from $2.0 million in fiscal 1995 to $2.2
million in fiscal 1996. During fiscal 1996, SPC realized gains on the sale of
investments of $0.6 million from the sale of Computer Concepts Corporation
("CCC") common stock and an additional $0.6 million of other income as a result
of penalty payments for late registration of such stock. In June 1994, SPC had
sold its Superbase product line to CCC for 2,031,175 shares of CCC's restricted
common stock. As part of such sale, CCC agreed to issue additional shares to SPC
if CCC failed to register such shares with the SEC for resale by SPC within
certain time periods or, in certain circumstances, if SPC realized less than a
specified price upon such resale. In September 1996, CCC and SPC entered into a
binding letter of intent, pursuant to which CCC agreed to pay SPC $619,420 and
issue to SPC 1,064,667 additional shares of CCC common stock as penalties for
late registration. In October 1996, SPC and CCC entered into a definitive
settlement agreement, reflecting the same terms and conditions, including
additional release of claims provisions, and SPC received the foregoing cash and
shares. As of September 30, 1996, SPC had sold 588,195 shares of the CCC stock.
As of October 21, 1996, SPC sold an additional 674,000 shares. It is anticipated
that SPC will attempt to sell the remaining CCC shares, approximately 1.8
million, over the next three fiscal quarters. As of September 30, 1996, the
closing price of the CCC common stock on the Nasdaq/NMS was $0.59.
 
     Interest income was $1.9 million, $2.0 million and $1.0 million in fiscal
years 1994, 1995 and 1996, respectively. Interest income increased slightly from
1994 to 1995 because of higher available interest rates offset by lower average
cash and short-term investment balances. Interest income in 1996 decreased
compared to 1995 because of lower average cash and short-term investment
balances.
 
                                       107
<PAGE>   116
 
  Income Tax Benefit
 
     SPC's effective tax rates were (25.7)%, (9.2)%, and (13.7)% for fiscal
years 1994, 1995 and 1996, respectively. In fiscal years 1994, 1995 and 1996,
SPC incurred income tax expense in certain foreign and local taxing
jurisdictions, though SPC incurred a pre-tax loss on a consolidated basis.
 
     Beginning in fiscal year 1993, SPC established a valuation allowance for
deferred tax assets, as realizability of such assets was not sufficiently
likely. If SPC generates taxable income in the United States in future years,
the valuation allowance may be reduced, which correspondingly may reduce SPC's
tax provision.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     During fiscal 1996, cash and short-term investments decreased by $15.8
million to $12.6 million. The decrease was the result of the net loss for the
year of $9.3 million less depreciation of $1.0 million, and non-cash
restructuring charges of $2.3 million and the reversal of income tax payables of
$1.5 million. Additionally, cash outflows during the year for Digital Paper,
Inc. installment payments totaled $1.65 million, restructuring and lease
payments totaled $5.4 million and accrued sales and marketing expenses were $1.2
million. SPC management believes that, in the absence of the Merger, if SPC can
attain its revenue and cash collection goals, its existing cash and short-term
investments and cash generated from operations, if any, should be sufficient to
meet its currently anticipated liquidity and capital expenditure requirements.
There can be no assurance, however, that SPC will be successful in attaining
such goals, nor that attaining such goals will have the desired effect on SPC's
cash resources. If SPC does not attain its revenue and cash collection goals or
if SPC's cash resources are not sufficient, it may be necessary to obtain
additional sources of financing which may or may not be available and upon
favorable terms.
 
     SPC's principal future resource commitments at September 30, 1996 consisted
primarily of purchase commitments for Digital Paper, Inc. and real estate lease
commitments (See Notes 7 and 11 of the Notes to Consolidated Financial
Statements).
 
     In fiscal 1996, SPC invoiced approximately 29% of its total sales in
foreign currencies, and expects this practice to continue. SPC's exposure for
foreign currency exchange gains and losses is partially mitigated, as SPC incurs
operating expenses in most of the currencies in which it invoices customers.
During fiscal 1995 and 1996, SPC hedged certain specific contractual obligations
denominated in foreign currency. As of September 30, 1996, SPC had no foreign
exchange contracts outstanding. SPC's foreign exchange gains and losses will
fluctuate from period to period depending on the movement in exchange rates.
 
     SPC estimates its consolidated tax net operating loss carryforwards to be
approximately $69 million at September 30, 1996. SPC expects that after giving
effect to the Merger, an "ownership change" will be deemed to have occurred
under Section 382 of the Code and the regulations thereunder with respect to it,
and that as a result thereof the use by the Combined Company of the net
operating loss carryforwards of SPC will be limited.

(1) All options in this table have exercise prices equal to the fair market
     value on the date of grant. The options generally become exercisable over a
     period of four years and expire seven years from the original date of
     grant. These options were granted under SPC's 1987, 1989, and 1991 Stock
     Option Plans.
 
(2) SPC granted options for 2,517,000 shares to employees in fiscal 1996 under
     the 1987, 1989 and 1991 Plans.
 
(3) Potential realizable value assumes that the stock price increases from the
     date of grant until the end of the option term (generally seven years) at
     the annual rate specified (5% and 10%). Annual compounding results in total
     appreciation of 41% (at 5% per year) and 95% (at 10% per year) for options
     with a seven year term. If the price of SPC's Common Stock were to increase
     at such rates from the price at 1996 fiscal year end ($1.8125 per share)
     over the next seven years, the resulting stock price at 5% and 10%
     appreciation would be $2.55 and $3.53 respectively. The assumed annual
     rates of appreciation are specified in SEC rules and do not represent SPC's
     estimate or projection of future stock price growth. SPC does not
     necessarily agree that this method can properly determine the value of an
     option.
 
(4) Mr. Salim resigned as a director and officer of SPC on August 12, 1996. Mr.
     Salim's options were canceled without having been exercised on September
     11, 1996.

COMPENSATION OF DIRECTORS
 
     Each of the directors who is not an employee of SPC receives an annual
retainer of $9,000 and a fee of $500 for each meeting of the SPC Board and each
meeting of a committee of the SPC Board attended. Non-employee directors also
participate in SPC's stock option plans. Currently, a single nonstatutory option
to purchase 15,000 shares of the SPC's Common Stock is automatically granted
under one of the stock option plans to each non-employee director upon the
appointment or election of such non-employee director to the Board of Directors
of SPC, regardless of whether such appointment or election is by the SPC Board
of Directors or the stockholders, and thereafter on the first market day of each
fiscal year until the maximum number of shares available for non-employee
directors is reached. See "SPC Certain Transactions."
 
REPRICING OF OPTIONS
 
REPORT OF THE SPC COMPENSATION COMMITTEE REGARDING EXCHANGE OF OPTIONS
 
     On September 3, 1996, the Board of Directors offered to all employees of
SPC (including officers of SPC) the opportunity to cancel outstanding stock
options with exercise prices in excess of $1.25 per share (the fair market value
of SPC Common Stock at that time) in exchange for options exercisable at $1.25
per share which were otherwise identical to the canceled options except that
during the six-month period commencing from the date of the exchange, the
exchanged options are not exercisable. The option exchange was an
acknowledgement of the importance to SPC of having equity incentives in the
hands of key employees. Stock options which are "out of the money" provide no
particular compensatory incentive if an employee is considering alternative
opportunities. The six month period during which the exchanged options may not
be exercised was viewed as a means of retaining the services of valued employees
for a longer period of time. The Committee decided to include officers in the
exchange because of the importance of their administrative and technical
leadership to the success of SPC's business.

MANAGEMENT CONTINUITY AGREEMENTS
 
     SPC currently has management continuity agreements (the "Management
Continuity Agreements") with each of its current officers, Daniel J. Fraisl,
Miriam K. Frazer, and Joseph V. Szczepaniak. The Management Continuity Agreement
with Ms. Frazer was entered into in February 1994 and the Management Continuity
Agreements with Mr. Fraisl and Mr. Szczepaniak were entered into
contemporaneously with the time each become an executive officer of SPC. (SPC
also has entered into management or key employee continuity agreements with
three of its key non-officer employees.) Under the terms of the Management
Continuity Agreements, in the event there is a "Change of Control" of SPC, which
is defined in the Management Continuity Agreements to include, among other
things, a merger or sale of assets of SPC, the exercisability and vesting of all
options held by such persons are accelerated. The Management Continuity
Agreement with each officer further provides that in the event that such officer
is "involuntarily terminated" within 18 months after a Change of Control, the
officer will receive 12 months severance pay and continued health and medical
benefits. Severance benefits to which an officer may become entitled under the
Management Continuity Agreements are reduced by an amount equal to the fair
market value of any accelerated options less the exercise price for such
options. The purpose of the Management Continuity Agreements is to ensure that
SPC will have the continued dedication of its senior management team by
providing such individuals with certain compensation arrangements, competitive
with those of other corporations, to provide sufficient incentive to the
individuals to remain with SPC, and to enhance their financial security, as well
as protect them against unwarranted termination in the event of a Change of
Control. The Management Continuity Agreements with the officers and two of the
three key employees will be superseded by the Employment Agreements that were
entered into with the Combined Company as of the Effective Time.

                            SPC CERTAIN TRANSACTIONS
 
     During fiscal 1995, SPC entered into the following three-year, non-interest
bearing loan agreements: (1) loan agreement with Irfan Salim, the then President
and Chief Executive Officer of SPC in the amount of $300,000; and (2) loan
agreement with Robert T. Iguchi, the then Vice President of North American Sales
and Service of SPC, in the amount of $117,000. Each of the foregoing loans is
secured by a second deed of trust on the respective borrowers' home. During the
third fiscal quarter of 1996, Mr. Iguchi repaid to SPC the outstanding balance
of his loan. For an explanation regarding Mr. Salim's repayment of his loan, see
Note 2 to the Summary Compensation Table.
 
     On October 23, 1996, the Board of Directors of SPC awarded to each of Dr.
Gilbert, Ms. Strom and Mr. Bertelsen, outside directors of SPC, options to
purchase 30,000 shares of SPC Common Stock at an exercise price of $1.25 (the
fair market value thereof on the date of grant), which options are exercisable
in three equal installments, on the date of grant and on the first and second
anniversaries of the date of grant.
 
     The Board of Directors of SPC has determined to pay a bonus of $25,000 to
each of Miriam K. Frazer, Daniel J. Fraisl and Joseph Szczepaniak, payable
following the first profitable fiscal quarter of the Combined Company.

                          COMPARISON OF CAPITAL STOCK
 
DESCRIPTION OF ALLEGRO CAPITAL STOCK
 
     Allegro's authorized capital stock currently consists of 18,000,000 shares
of Allegro Common Stock, $.001 par value per share, 2,000,000 shares of Class A
Convertible Preferred Stock, $.001 per value per share and 2,000,000 shares of
Serial Preferred Stock, $.001 par value per share of which 60,520 shares have
been designated as Class B Voting Preferred Stock. In the event that Allegro
stockholders approve proposal (2), the number of authorized shares of Allegro
Common Stock will be increased to 30,000,000, and in the event that Allegro
stockholders approve proposal (3), the Class A Convertible Preferred Stock will
be eliminated.
 
ALLEGRO COMMON STOCK
 
     Holders of Allegro Common Stock do not have subscription, redemption,
conversion or preemptive rights. Each share of Allegro Common Stock is entitled
to participate pro rata in distribution upon liquidation, subject to the rights
of holders of preferred stock, and to one vote on all matters submitted to a
vote of stockholders. The holders of Allegro Common Stock may receive cash
dividends as declared by the Board of Directors out of funds legally available
therefor, subject to the rights of any holders of preferred stock.
 
     Holders of Allegro Common Stock, together with the holder of shares of
Allegro's Class B Voting Preferred Stock, are entitled to elect all directors.
Allegro's Board of Directors consists of three classes, each of which serves for
a term of three years. At each annual meeting of the stockholders the directors
in only one class will be elected. The holders of Allegro Common Stock do not
have cumulative voting rights, which means that the holders of more than half of
the shares voting for the election of a class of directors can elect all of the
directors of such class and in such event the holders of the remaining shares
will not be able to elect any of such directors.
 
PREFERRED STOCK
 
  Class A Convertible Preferred Stock
 
     Allegro's Certificate, as amended, authorizes the issuance of up to
2,000,000 shares of preferred stock, par value $.001 per share, denominated as
the "Class A Convertible Preferred Stock". The liquidation preference of each
share of Class A Convertible Preferred Stock equals $1.00. Dividends on the
Class A Convertible Preferred Stock accrue at a rate equal to 10% per annum
commencing six months after the issuance thereof and are payable only upon a
mandatory redemption of the Class A Convertible Preferred Stock. 1,190,250
shares of Class A Convertible Preferred Stock were issued in June and November
1994 in connection with a private placement transaction. All of these shares of
Class A Convertible Preferred Stock converted into 491,821 shares of Allegro
Common Stock upon the completion of Allegro's IPO.
 
     The former holders of a majority of the Class A Convertible Preferred
Stock, together with MS Farrell, have the right to cause Allegro to register the
shares of Allegro Common Stock they obtained upon conversion of the Class A
Convertible Preferred Stock, and such holders also have piggyback registration
rights and come-along rights with respect to certain sales of Allegro Common
Stock by Barry A. Cinnamon. Each share of Allegro Common Stock obtained upon
conversion of shares of Class A Convertible Preferred Stock may not be sold
until December 7, 1997 without the written consent of MS Farrell.
 
  Class B Voting Preferred Stock
 
     In November 1994, the Board of Directors of Allegro created a new class of
Serial Preferred Stock of Allegro designated as the Class B Voting Preferred
Stock, Series A, consisting of 60,520 shares of Serial Preferred Stock, par
value $.001 per share. Allegro has issued all of such shares of Class B Voting
Preferred Stock, Series A ("Class B Voting Preferred Stock") to Barry A.
Cinnamon.
 
     The Class B Voting Preferred Stock votes together with the Allegro Common
Stock other than, pursuant to the Delaware General Corporation Law, with respect
to proposals to increase the number of authorized shares of Allegro Common Stock
and certain other specified matters. Each share of Class B Voting Preferred
 
                                       118
<PAGE>   127
 
Stock entitles the holder thereof to ten (10) votes on each matter subject to
stockholder approval. Accordingly, by virtue of his ownership of these shares of
Class B Voting Preferred Stock, Barry A. Cinnamon has an additional 605,200
votes with respect to almost all matters subject to stockholder approval. Shares
of Class B Voting Preferred Stock have no right to dividends and have a
liquidation preference of $.001 per share.
 
  Other Classes of Preferred Stock
 
     The Allegro Board of Directors is authorized by Allegro's Certificate of
Incorporation to issue up to an additional 1,939,480 shares of one or more
series of Serial Preferred Stock, $.001 par value. Other than the shares of
Class B Voting Preferred Stock referred to above, no shares of such serial
preferred stock have been authorized for issuance by the Allegro Board, and
Allegro has no present plans to issue any such shares. In the event that the
Allegro Board does issue additional shares of serial preferred stock, it may
exercise its discretion in establishing the terms of such serial preferred
stock. In the exercise of such discretion, the Allegro Board may determine the
voting rights, if any, of the series of preferred stock being issued, which
could include the right to vote separately or as a single class with the Allegro
Common Stock and/or other series of preferred stock; to have more or less voting
power per share than that possessed by the Allegro Common Stock or other series
of preferred stock; and to vote on certain specified matters presented to the
stockholders or on all of such matters or upon the occurrence of any specified
event or condition. On liquidation, dissolution or winding up of Allegro, the
holders of preferred stock may be entitled to receive preferential cash
distributions fixed by the Allegro Board of Directors when creating the
particular series thereof before the holders of the Allegro Common Stock are
entitled to receive anything. Preferred stock authorized by the Allegro Board
could be redeemable or convertible into shares of any other class or series of
stock of Allegro.
 
     The issuance of preferred stock by the Allegro Board could adversely affect
the rights of holders of the Allegro Common Stock by, among other things,
establishing preferential dividends, liquidation rights or voting powers. The
issuance of preferred stock could be used to discourage or prevent efforts to
acquire control of Allegro through the acquisition of shares of Allegro Common
Stock.

     The Transfer Agent and Registrar for the Allegro Common Stock is American
Stock Transfer and Trust Company, 40 Wall Street, New York, NY 10005, telephone

DESCRIPTION OF SPC CAPITAL STOCK
 
     The authorized capital stock of SPC consists of 30,000,000 shares of SPC
Common Stock, $.001 par value per share, and 2,000,000 shares of Preferred
Stock, $.001 par value per share (the "Preferred Stock").
 
  SPC Common Stock
 
     As of the SPC Record Date, there were approximately           shares of SPC
Common Stock outstanding held of record by approximately           stockholders.
The SPC Common Stock is listed on the Nasdaq/NMS under the trading symbol
"SPCO." Holders of SPC Common Stock are entitled to one vote per share on all
matters to be voted upon by the stockholders and to receive such lawful
dividends as may be declared by SPC's Board of Directors. In the event of the
liquidation, dissolution or winding up of SPC, the holders of shares of SPC
Common Stock will be entitled to share ratably in SPC's assets. All outstanding
shares of SPC Common Stock are fully paid and nonassessable.
 
  Preferred Stock
 
     The SPC Board has the authority, without any further vote or action by the
stockholders, to provide for the issuance of up to 2,000,000 shares of Preferred
Stock in series, to establish from time to time the number of shares to be
included in each such series, to fix the designations, preferences, limitations
and relative, participating, optional or other special rights and qualifications
or restrictions of the shares of each series, and
 
                                       119
<PAGE>   128
 
to determine the voting powers, if any, of such shares. The issuance of
Preferred Stock could adversely affect, among other things, the rights of
existing stockholders or could delay or prevent a change in control of SPC
without further action by the stockholders. The issuance of Preferred Stock
could decrease the amount of earnings and assets available for distribution to
holders of SPC Common Stock. In addition, any such issuance could have the
effect of delaying, deferring or preventing a change in control of SPC and could
make the removal of the present management of SPC more difficult. SPC has no
current plans to issue any Preferred Stock.
 
     The Transfer Agent and Registrar for the SPC Common Stock is Chase Mellon
Shareholder Services, 50 California Street, 10th Floor, San Francisco, CA 94111,
telephone number: (415) 954-9516.
 
SPC STOCKHOLDER RIGHTS PLAN
 
     On April 23, 1991, SPC declared a distribution to stockholders of record on
May 31, 1991 of one Preferred Share Purchase Right ("Right") for each
outstanding share of SPC Common Stock. Under certain circumstances, a Right may
be exercised to purchase one-thousandth of a share of SPC Series A preferred
stock at an exercise price of $150. Under these circumstances, the Rights become
exercisable if a person (an "Acquiring Person") acquires 15% or more of the SPC
Common Stock or announces a tender offer for 15% or more of the SPC Common
Stock. The Rights many be redeemed by SPC at a price of $0.01 per Right at any
time prior to the tenth day after a person becomes an Acquiring Person. Upon
occurrence of certain events after the Rights become exercisable, each Right
would entitle the Right holder to purchase SPC Common Stock or common stock of
the Acquiring Party having a market value of twice the exercise price of the
Right, except that the Acquiring Party and related holders would not be able to
purchase common stock on these terms. The Rights are non-voting and expire in
2001. Allegro will not become an Acquiring Party as a result of the Merger, and
the Rights will not become exercisable in connection with the Merger.
 
COMPARISON OF CAPITAL STOCK
 
     The following discussion summarizes the material differences between the
rights of holders of Allegro Common Stock and holders of SPC Common Stock. As
each of Allegro and SPC is organized under and subject to the laws of Delaware,
these differences arise from various provisions of the Certificate of
Incorporation and By-laws of each of Allegro and SPC. This summary does not
purport to be complete and is qualified in its entirety by reference to the
Certificate of Incorporation and By-laws of Allegro and SPC.
 
     Upon consummation of the Merger, the holders of SPC Common Stock who
receive Allegro Common Stock under the terms of the Agreement will become
stockholders of Allegro. As stockholders of SPC, their rights are currently
governed by Delaware law and by the SPC Certificate of Incorporation, as amended
(the "SPC Certificate"), and By-laws (the "SPC By-laws"). As stockholders of
Allegro, their rights will be governed by Delaware law and by the Allegro
Certificate and Allegro By-laws (the "Allegro By-laws").
 
  Special Meeting of Stockholders
 
     The Allegro Certificate and Allegro By-laws each provide that special
meetings may be called by the Chairman of the Board, the President or a majority
of the Board of Directors, or upon written request of stockholders owning at
least sixty-six and two-thirds percent of the entire capital stock issued and
outstanding and entitled to vote. The SPC By-laws provide that special meetings
may be called by the Board of Directors, by the Chairman of the Board, by the
President or by one or more stockholders who hold not less than ten percent in
interest of the capital stock entitled to vote at a meeting. Accordingly, it
would be expected to be significantly more difficult for an SPC stockholder
owning between 10% and 66  2/3% of the outstanding Allegro Common Stock to cause
a meeting of Allegro stockholders to be held.
 
  Action by Consent of Stockholders
 
     Under Delaware law, unless the certificate of incorporation provides
otherwise, any action to be taken by stockholders may be taken without a
meeting, without prior notice, and without a vote, if the stockholders having
the number of votes that would be necessary to take such action at a meeting at
which all stockholders
 
                                       120
<PAGE>   129
 
were present and voted consent to the action in writing. The SPC Certificate,
however, provides that any action required or permitted to be taken by its
stockholders cannot be effected by written consent, but must be effected at a
duly called annual or special meeting of stockholders.
 
  Cumulative Voting
 
     Under Delaware law, a corporation may provide in its certificate of
incorporation for cumulative voting by stockholders in elections of directors
(i.e., each stockholder casts as many votes for directors as he has shares of
stock multiplied by the number of directors to be elected). The SPC Certificate
provides for cumulative voting. The Allegro Certificate does not provide for
cumulative voting, so holders of Allegro Common Stock after the Merger will not
have cumulative voting rights.
 
  Classification of the Board of Directors
 
     The Allegro Certificate provides for the classification of its Board of
Directors into three classes. The Allegro By-laws provide that the total number
of directors shall not be less than three nor more than eleven. As a result of
such classification, a person wishing to propose alternative nominees for
election to the Allegro Board of Directors would be able to propose nominees for
only one-third of the Board at a time. The SPC Certificate does not provide for
classes of directors. The SPC By-laws provide that the number of directors shall
be five.
 
  Removal of Directors
 
     The Allegro By-laws provide that a director may be removed from office at
any time by majority vote of the outstanding shares of stock entitled to vote.
Nevertheless, as Allegro has a classified board, Section 141 of the Delaware
General Corporation Law provides that shareholders may effect such removal only
for cause. The SPC By-laws provide that a director may be removed, with or
without cause, by a majority vote of the shares entitled to vote, provided that
if stockholders are entitled to cumulative voting, and if less than the entire
board is to be removed, no director can be removed without cause if the votes
cast against removal of such director would be sufficient to elect him or her if
then cumulatively voted at an election of the entire board.
 
  Exculpation of Directors
 
     Each of the Allegro Certificate and the SPC Certificate provide that no
director shall be personally liable to Allegro and SPC, respectively, or their
respective stockholders for monetary damages for breaches of fiduciary duty
except where such exculpation is expressly prohibited by law.
 
  Indemnification of Directors, Officers and Others
 
     The Allegro Certificate authorizes Allegro to provide indemnification to
its agents to the maximum extent legally permissible. The Allegro By-laws
provide for indemnification of any person made a party to any action, suit or
proceeding by reason of the fact that he is or was a director, officer, employee
or agent of the corporation. Allegro has entered into indemnification agreements
with each of its directors and executive officers. The SPC By-laws provide for
indemnification to its directors and executive officers to the maximum extent
legally permissible and that the corporation has the power to provide
indemnification for its employees and agents. SPC has also entered into
indemnification agreements with each of its directors and officers.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
  ALLEGRO NEW MEDIA, INC.
 
     We have audited the accompanying balance sheet of Allegro New Media, Inc.
as of December 31, 1995 and the related statements of operations, stockholders'
(deficit) equity and cash flows for the years ended December 31, 1995 and 1994.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Allegro New Media, Inc. at
December 31, 1995 and the results of its operations and its cash flows for the
years ended December 31, 1995 and 1994 in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Business/Concentration of Credit Risk
 
     Allegro New Media, Inc. (the "Company"), is a publisher of interactive
compact disc ROM (Read Only Memory) software products to retail and wholesale
outlets and original equipment manufacturers in the United States. The Company
performs periodic credit evaluations of its customers but generally does not
require collateral. Sales to all customers representing greater than 10% of net
sales (2 in 1995 and 2 in 1994) totaled approximately 36% and 24% of total net
sales for 1995 and 1994 respectively. Gross accounts receivable from these
customers totaled $305,300 at December 31, 1995.
 
  Revenue Recognition
 
     Revenue is generally recognized upon shipment of products to customers and
is recorded net of allowances for anticipated returns. Certain customers are
provided goods on a consignment basis. Revenues on these transactions are
recognized upon the sale of products to the ultimate customer.
 
  Cash Equivalents
 
     Cash equivalents consist of highly liquid investments with a maturity of
three months or less when purchased.
 
  Inventories
 
     Inventories are stated at the lower of cost (first-in, first-out) or
market.
 
  Royalty Advances
 
     Non-refundable royalty payments in connection with licensing contracts for
the Company's products are generally amortized based on product sales.
Management evaluates the future realization of royalty advances periodically and
charges to cost of goods sold any amounts they believe will not be recovered
through future sales.
 
  Product Development Costs
 
     Product development costs consist principally of compensation to employees
and related costs paid to outside consultants. All product development costs are
expensed as incurred.
 
  Equipment, Furniture, Fixtures and Leasehold Improvements
 
     Equipment, furniture and fixtures and leasehold improvements are stated at
cost. Depreciation for financial reporting purposes is provided on a
straight-line basis based upon the estimated useful lives of the related assets,
generally 3 to 7 years. Leasehold improvements are amortized on a straight-line
basis over the shorter of the life of the improvement or the remainder of the
lease term.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principals requires management to make estimates and
assumptions that affect the reported amounts in the financial statements and
accompanying notes. These estimates principally include provisions for sales
returns and allowances. Actual results could differ from these estimates.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Loss Per Share
 
     Net loss per share is computed based upon the weighted average number of
shares of common stock and common share equivalents outstanding during the
periods presented. In accordance with Securities and Exchange Commission Staff
Accounting Bulletin No. 83, shares issuable upon exercise of options granted
during the twelve months immediately preceding the initial public offering have
been included in the calculation of shares used in computing net loss per share
as if they were outstanding for all periods presented using the treasury stock
method. For the period subsequent to the initial public offering, common share
equivalents resulting from outstanding options to purchase common stock are
excluded as the impact is anti-dilutive.
 
  Stock Based Compensation
 
     In October 1995, the FASB issued Statement No. 123, Accounting for
Stock-Based Compensation. SFAS No. 123 encourages but does not require entities
to adopt the fair value based method of accounting for all employee stock
compensation plans, under which compensation cost is measured based on the fair
value of the award at the grant date and recognized over the service period.
Entities may continue to account for these plans using the intrinsic value based
method of accounting, under which compensation cost is measured as the excess,
if any, of the quoted market price of the stock at the grant date over the
amount an employee must pay to acquire the stock. Statement 123 is effective for
years beginning after December 15, 1995. The Company plans to continue to use
the intrinsic value based method to measure compensation costs for these plans.
 
2. INVENTORIES
 
     Inventories at December 31, 1995 consist of the following:

                                                                            $225,013
                                                                            ========
</TABLE>
 
3. INCOME TAXES
 
     The liability method is used in accounting for income taxes. Under this
method, deferred tax assets and liabilities are determined based on differences
between financial reporting and tax basis of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.
 
     At December 31, 1995, the Company has available net operating loss
carryforwards of approximately $2,327,000 for federal income tax purposes that
expire beginning in 2009, $2,503,000 for state income tax purposes that expire
beginning in 2000, and deductible temporary differences of $476,000 which result
from non-deductible inventory and accounts receivable reserves. For financial
statement purposes, a valuation allowance has been recognized to fully offset
the deferred tax asset related to these carryforwards and temporary differences
(approximately $1,135,000 and $279,000 at December 31, 1995 and 1994,
respectively).
 
4. SHAREHOLDERS' EQUITY AND EXTRAORDINARY ITEM
 
     During 1994 the Company issued an aggregate of 1,190,250 shares of its
Class A Cumulative, Convertible, Redeemable 10% Preferred Stock ("Redeemable
Preferred Stock") in a private placement transaction. In accordance with its
terms, all of the shares of Redeemable Preferred Stock were converted into
 
                                       F-9

                            ALLEGRO NEW MEDIA, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
an aggregate of 491,821 shares of the Company's common stock upon completion of
the Company's initial public offering in December 1995.
 
     The Redeemable Preferred Stock was recorded at fair value at the date of
issuance less direct issuance costs and had a carrying value of $972,185 at the
date of conversion. No dividends were declared or paid on the Redeemable
Preferred Stock.
 
     In December 1993, the Company issued warrants for the purchase of up to
446,402 shares of its common stock at a per share price equal to par value to
certain parties in connection with a proposed offering of the Company's
Redeemable Convertible Preferred Stock. These warrants were exercisable only
upon the successful completion of the sale of at least 1,000,000 shares of the
Company's Redeemable Preferred Stock. As a result of the sale of 1,190,250
shares of the Company's Redeemable Preferred Stock during 1994, the holders of
these warrants purchased a total of 387,354 shares of the Company's common stock
for an aggregate purchase price of $387. These shares had an aggregate fair
value of $203,000 which was considered a direct cost of issuance of the
Redeemable Preferred Stock at that date.
 
     In connection with certain financing transactions during 1993, certain of
the then existing employee/stockholders of the Company agreed to place an
aggregate of 1,000,000 newly issued shares of the Company's common stock into
escrow. Under the terms of the escrow agreement such shares are to be released
to the stockholders based upon the Company achieving certain financial results,
as defined. When such escrowed shares are released, Securities and Exchange
Commission rules require recognition by the Company of compensation expense
based on the fair value of the shares at the date of release. The escrow
agreement expires the earlier of the release of all of the escrow shares or June
30, 1999. Any shares not released are to be returned to the Company. During
1994, with the approval of such stockholders, 677,500 of these escrowed shares
were canceled.
 
     On March 31, 1995, certain existing stockholder employees surrendered to
the Company a total of 280,000 shares of the Company's common stock and agreed
to place an additional 220,000 shares under the terms of an additional escrow
agreement. These shares are to be released to the stockholders upon the Company
attaining certain financial results, as defined. Release of these shares will
also result in recognition of compensation expense based on the fair value of
the shares at the date of release.
 
     During 1994 a principal employee stockholder purchased 60,520 shares of the
Company's Class B Voting Preferred Stock, Series A ("Class B Voting Preferred")
for an aggregate purchase price of $61. The Class B Voting Preferred has maximum
liquidation rights of $.001 per share, but is not permitted to receive
dividends. The holders of Class B Voting Preferred are entitled to 10 votes per
share. These shares are entitled to no other benefits of ownership.
 
     During 1995, the Company issued 14% short-term notes payable aggregating
$559,000 which were payable upon the earlier of December 25, 1995 or the
Company's receipt of sufficient funds from subsequent sales of securities. In
August 1995, the Company completed the sale of $1,250,000 principal amount of
10% notes due the earlier of the completion of an initial public offering of the
Company's common stock or February 28, 1997. The Company received net proceeds
of $1,066,233, a portion of which was used to repay all of the short-term 14%
notes payable described above. In addition to the 10% notes, the holders were
entitled to receive a number of shares of the Company's common stock equal to
the principal amount of the notes divided by the issuance price in an initial
public offering of such common stock. At the date of issuance and based on a
fair value of $5.00 per share, the Company allocated $777,217 (net of offering
costs of $160,283) to the equity component and $312,500 to the 10% notes
payable. The carrying amount of these notes was increased periodically (using
the interest method) to equal the principal balance at maturity.
 
     In December 1995, the Company completed an initial public offering of
1,033,000 shares of its common stock and received net proceeds of $4,156,411.
Upon the completion of this offering the Company repaid all of the 10% notes
payable and issued 243,902 shares of its common stock. The Company incurred an

extraordinary loss of $990,928 relating to deemed interest and deferred
financing costs associated with the repayment of the 10% notes payable.
 
     In connection with a license agreement, the licensor has been granted an
option to purchase up to 100,000 shares of the Company's common stock at a price
per share equal to the initial public offering price (less underwriting
discounts). This agreement expires on July 31, 1998.
 
5. LONG-TERM INCENTIVE PLAN
 
     In December 1993, the Company's Board of Directors adopted a long-term
incentive plan (the "Incentive Plan"). Under the terms of the Incentive Plan,
the Company's Board of Directors or a committee thereof, may grant options,
stock appreciation rights, restricted stock or performance grants of the
Company's common stock, cash or other assets to employees, consultants and
others who perform services for the Company at such prices as may be determined
by the Board of Directors (which price may be no less than 85% of the fair
market value of the common stock on the date of grant in the case of
nonqualified stock options). The specific terms of the grants are at the sole
discretion of the Company's Board of Directors or Administrative Committee of
the Incentive Plan. The maximum number of shares subject to the Incentive Plan
as of December 31, 1995 is 400,000. The options currently outstanding vest over
a period of up to five years and expire after 10 years.
 
6. STOCK OPTIONS
 
     A summary of changes in outstanding options under the Incentive Plan is as

Board of Directors
  SERIF, INC.
 
     We have audited the accompanying balance sheets of Serif, Inc. as of
December 31, 1995 and 1994 and the related statements of operations and
accumulated deficit and cash flows for the years ended December 31, 1995 and
1994. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Serif, Inc. at December 31,
1995 and 1994 and the results of its operations and its cash flows for the years

                         NOTES TO FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Business/Concentration of Credit Risk
 
     Serif, Inc. (the "Company"), develops and publishes a line of desktop
publishing software products. The Company sells its products directly to
customers on a telemarketing basis and to distributors and other re-sellers in
the United States and Canada. The Company performs periodic credit evaluations
of its customers but generally does not require collateral. No individual
customer represents a significant percentage of sales.
 
  Revenue Recognition
 
     Revenue is generally recognized upon shipment of products to customers and
is recorded net of allowances for anticipated returns. Certain customers are
provided goods on a consignment basis. Revenues on these transactions are
recognized upon the sale of products to the ultimate customer.
 
     Revenues from the licensing of proprietary software are recognized upon
delivery, in accordance with the contract terms.
 
  Cash Equivalents
 
     Cash equivalents consist of highly liquid investments with a maturity of
three months or less when purchased.
 
  Inventories
 
     Inventories are stated at the lower of cost (first-in, first-out) or
market.
 
  Product Development Costs
 
     Product development costs consist principally of compensation to employees,
related costs paid to outside consultants and an affiliated company, and
technology and software the Company may acquire for use in its products. All
product development costs are expensed as incurred.
 
  Equipment, Furniture and Leasehold Improvements
 
     Equipment, furniture and leasehold improvements, including assets under
capitalized leases are stated at cost. Depreciation, including amortization of
assets under capitalized leases is provided on a straight-line basis based upon
the estimated useful lives of the related assets, generally 3 to 7 years.
Leasehold improvements are amortized on a straight-line basis over the shorter
of the life of the improvement or the remainder of the lease term.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts in the financial statements and
accompanying notes. These estimates principally include provisions for sales
returns and allowances. Actual results could differ from these estimates.

4. INCOME TAXES
 
     The liability method is used in accounting for income taxes. Under this
method, deferred tax assets and liabilities are determined based on differences
between financial reporting and tax basis of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.
 
     At December 31, 1995, the Company has available net operating loss
carryforwards of approximately $566,000 that expires at December 31, 2009
($110,000) and December 31, 2010 ($456,000). As a result of the transactions
described in Note 8 below, utilization of the Company's net operating loss
carryforward will be subject to significant limitations.

                      INDEPENDENT AUDITORS' REPORT TO THE
                  BOARD OF DIRECTORS OF SERIF (EUROPE) LIMITED
 
     We have audited the accompanying financial statements set out on pages F-21
to F-29 of Serif (Europe) Limited. These financial statements were audited in
accordance with UK Auditing Standards which do not differ in any significant
respect from United States Generally Accepted Auditing Standards.
 
BASIS OF OPINION
 
     Our audit included an examination, on a test basis, of evidence relevant to
the amounts and disclosures in the financial statements. It also included an
assessment of the significant estimates and judgements made by the directors in
the preparation of the financial statements, and of whether the accounting
policies were appropriate to the company's circumstances, consistently applied
and adequately disclosed.
 
     We planned and performed our audit so as to obtain all the information and
explanations which we considered necessary in order to provide us with
sufficient evidence to give reasonable assurance that the financial statements
were free from material misstatement, whether caused by fraud or other
irregularity or error. In forming our opinion we also evaluated the overall
adequacy of the presentation of information in the financial statements.
 
OPINION
 
     In our opinion, the financial statements set out on pages F-21 to F-29
present fairly, in all material respects, the financial position of the company
at December 31, 1995 and the results of its operations for each of the two years
in the period ended December 31, 1995 in conformity with generally accepted
accounting principles in the United Kingdom which differ in certain respects
from those followed in the United States (see Note 16 to the financial
statements).

                      FOR THE YEAR ENDED 31 DECEMBER 1995
 
     The accounts take into consideration events occurring between 31 December
1995 and the date of their approval by the Board of Directors.
 
1. ACCOUNTING POLICIES
 
     There have been no changes in accounting policies during the year.
 
     a. These accounts have been prepared under the historical cost convention
        and in accordance with accounting standards as defined in the Companies
        Act 1985, as amended, of Great Britain and have been reformatted for the
        purpose of the Securities and Exchange Commission filings for Allegro
        New Media Inc. In preparing these accounts the comparative results have
        been amended to show the 12 month period to December 31, 1994 from the
        15 month statutory period to December 31, 1994.
 
     b. Turnover represents the net amount of invoices to customers less credit
        notes for goods returned, excluding VAT.
 
     c. Depreciation is provided on the cost less estimated residual values of
        tangible assets over their estimated useful lives.
 
     The following rates and bases apply:
 
<TABLE>
    <S>                                                           <C>
    Office equipment............................................  15% Straight Line
    Computer hardware...........................................  25% Straight Line
    Fixtures and fittings.......................................  15% Straight Line
    Show equipment..............................................  16.7% per Show Attended
    Motor vehicles..............................................  25% Straight Line
</TABLE>
 
     d. Inventories are stated at the lower of cost and net realisable value.
        Cost is based on the cost of purchase on a first in, first out basis.
        Finished goods include the relevant proportion of overheads. Net
        realisable value is based on estimated selling price less further costs
        to completion and disposal.
 
     e. Provision is made for taxation deferred in respect of all material
        timing differences between the treatment of certain items for taxation
        and accounting purposes, only to the extent that it is probable that the
        liability will become payable in the foreseeable future.
 
     f. Transactions denominated in foreign currencies are translated into
        sterling at the rate of exchange ruling at the date of the transaction.
        Assets and liabilities denominated in foreign currencies are translated
        into sterling at the rate of exchange ruling at the balance sheet date.
 
     g. Rentals payable under operating leases are charged to the profit and
        loss account as they are incurred.
 
     h. Research and development expenditure is written off to the profit and
        loss account in the period in which it is incurred. Development
        expenditure is written off in the same way unless the directors are
        satisfied as to the technical, commercial and financial viability of
        individual projects. In this situation, the expenditure is deferred and
        amortised at a rate of 1% of turnover (less applicable expenses) per
        period.

15. SUBSEQUENT EVENT
 
     On July 31, 1996, Allegro New Media, Inc., (Allegro) a publicly owned
company incorporated in the United States, acquired all of the issued ordinary
and preference shares of Serif (Europe) Limited in a share for share
transaction. In addition, Allegro acquired all of the outstanding common stock
of Serif, Inc. in a similar transaction.
 
16. DIFFERENCES BETWEEN UNITED KINGDOM AND UNITED STATES GENERALLY ACCEPTED
ACCOUNTING PRINCIPLES
 
     The accounting policies, under which the financial statements of Serif
(Europe) Limited are prepared, conform with generally accepted accounting
principles in the United Kingdom (UK GAAP), which differ in certain respects
from generally accepted accounting principles in the United States (US GAAP).
Differences having a significant effect on the profit/(loss) and shareholders
funds are set out below.
 
  Research and product development
 
     Under UK GAAP certain research and product development costs are
capitalized and amortized over future periods. Under US GAAP all research and
product development costs are written off as incurred.
 
  Taxation
 
     Deferred taxation is not provided where, in the opinion of the directors,
no tax liability is likely to arise in the foreseeable future. However, US GAAP
requires full provision for deferred taxes using the liability method, and
requires an evaluation as to the recoverability of deferred tax assets.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Stockholders and Board of Directors of
  SOFTWARE PUBLISHING CORPORATION:
 
     We have audited the accompanying consolidated balance sheet of Software
Publishing Corporation and subsidiaries as of September 30, 1995 and 1996, and
the related consolidated statement of operations, stockholders' equity and cash
flows for each of the years in the two-year period ended September 30, 1996.
These consolidated financial statements are the responsibility of Software
Publishing Corporation's management. Our responsibility is to express an opinion
on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the 1995 and 1996 consolidated financial statements
referred to above present fairly, in all material respects, the financial
position of Software Publishing Corporation and subsidiaries as of September 30,
1995 and 1996, and the results of their operations and cash flows for each of
the years in the two-year period ended September 30, 1996 in conformity with
generally accepted accounting principles.

                SOFTWARE PUBLISHING CORPORATION AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) DESCRIPTION OF COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Description of Company
 
     Software Publishing Corporation (SPC) is engaged in the marketing and
development of personal computer software. SPC sells primarily to distributors
and resellers of personal computer software.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of Software
Publishing Corporation and its wholly owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated. SPC's foreign
operations are considered to be an extension of SPC's United States (U.S.)
operations. As a result, the U.S. dollar is the functional currency for SPC's
foreign subsidiaries. Gains and losses attributed to the remeasurement of
foreign subsidiaries' financial statements, as well as gains and losses
resulting from foreign currency transactions, are included in the results of
operations.
 
  Revenue Recognition
 
     Revenue is generally recognized at the time of shipment, net of allowances
for estimated future returns for inventory stock rotation and excess quantities
in the distribution channel.
 
  Inventories
 
     Inventories are stated at the lower of first-in, first-out cost or market
and consist mostly of finished goods.
 
  Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the related assets estimated useful lives, which
range from 3 to 5 years. Leasehold improvements are amortized on the
straight-line basis over the lesser of the estimated useful lives or the
remaining lease terms.
 
  Software Development Costs
 
     Costs incurred in the development of new software products and enhancements
to existing software products are expensed as incurred until technological
feasibility has been established. To date, SPC's software development has been
completed concurrent with the establishment of technological feasibility, and
accordingly, no costs have been capitalized.
 
  Income Taxes
 
     SPC utilizes an asset and liability method whereby the expected future tax
consequences of temporary differences between the book and tax basis of assets
and liabilities are recognized as deferred tax assets and liabilities. A
valuation allowance is recorded for any deferred tax assets for which
realization is not likely.
 
  Net Loss Per Common Share
 
     Net loss per common share has been computed using the weighted average
number of common shares outstanding during each year.
 
  Concentration of Credit Risk
 
     SPC's investment portfolio consists of equity securities and short-term
investment grade securities. SPC's accounts receivable are derived from sales to
customers, principally distributors of personal computer software,

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
located primarily in North America, Latin America, Europe and the Pacific Rim.
SPC performs credit evaluations of its customers and has established sufficient
allowances for potential credit losses.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
(2) CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
     Cash, cash equivalents and short-term investments consist primarily of U.S.
government obligations, municipal obligations, equity securities, and commercial
paper, all of which are carried at fair market value. Investments with
maturities in excess of 90 days at the time of acquisition are considered
short-term investments.
 
     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 115, "Accounting for Certain Investments in Debt and
Equity Securities" (FAS 115). SPC adopted the provisions of FAS 115 effective
October 1, 1994. Under the provisions of FAS 115, SPC has classified its
investments in debt and equity securities as "available-for-sale." Such
investments are now recorded at fair value, with unrealized gains and losses
reported as a separate component of stockholders' equity. Interest income is
recorded using an effective interest rate, with the associated discount or
premium amortized to interest income.
 
     The cost of securities sold is based on the specific identification method.
In accordance with the provisions of FAS 115, prior period financial statements
have not been restated to reflect the change in accounting principle. The
cumulative effect as of October 1, 1994 of adopting FAS 115 was immaterial.
 
     As of September 30, 1996, available-for-sale securities consisted of the
following (in thousands):

(5) REDEEMABLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY
 
  Redeemable Preferred Stock
 
     In fiscal 1991, SPC issued 9,028 shares of Series B preferred stock, $0.001
par value, representing all of the authorized shares of Series B preferred
stock. Holders of this stock were entitled, subject to certain conditions, to
cumulative annual dividends of $50.00 per share. All outstanding shares of the
Series B preferred stock had been redeemed for $1,000 per share plus accrued and
unpaid dividends by September 30, 1994.
 
  Stock Option Plans
 
     Under SPC's stock option plans, 6,102,500 shares of common stock have been
reserved for issuance as incentive or nonstatutory options to employees,
including officers and directors, or consultants.
 
     Options under the plans may be granted for periods of up to ten years, and
at prices no less than fair value at the date of grant as determined by the
Board of Directors, except for the 1987 and 1989 plans for which nonstatutory
options can be issued with an exercise price no lower than 50% of fair value and
the 1991 plan for which nonstatutory options can be issued with an exercise
price no lower than 85% of fair value. To date all options have been issued at
fair value. Options become exercisable at such times and under such conditions
as determined by the Board of Directors. Options currently outstanding typically
vest over a four-year period. At September 30, 1996, 3,047,663 options were
outstanding of which 349,155 were vested and will become exercisable following
the six month holding period.
 
     In July 1994, 633,912 options held by non-officer employees with exercise
prices greater than $3.875 per share were canceled, and an equal number of new
options were issued with an exercise price of $3.875 under the same terms as the
canceled options, except that the new options had a term of seven years from
date of grant, were unvested on the date of grant and became exercisable over a
four-year vesting schedule from the date of grant.
 
     In September 1996, SPC offered to all employees, including officers, the
opportunity to cancel substantially all outstanding stock options with exercise
prices in excess of $1.25, the fair market value of the common stock on the date
of the offer, in exchange for options exercisable at $1.25 per share. The
exchanged options are identical to the canceled options, except that during the
six month period commencing from the date of the exchange, the exchanged options
are not exercisable.

  Employee Stock Purchase Plan
 
     SPC established an Employee Stock Purchase Plan (the ESPP) in October 1984,
under which 925,000 shares of common stock were reserved for issuance to
employees meeting minimum employment criteria. The ESPP provides that issuance
of shares may not result in the employee's ownership (including options to
purchase shares) of 5% or more of total outstanding shares. In addition, the
fair value of shares made available to any employee for purchase under the ESPP
may not exceed $25,000 in any calendar year. Employees may participate through
payroll deductions in amounts related to their base compensation. The
participant's purchase price is 85% of the lower of fair market value at the
beginning or the end of each six month offering period. As of September 30,
1996, shares issued under the ESPP aggregated 857,567.
 
  Stockholder Rights Plan
 
     On April 23, 1991, SPC declared a distribution to stockholders of record on
May 31, 1991 of one Preferred Share Purchase Right ("Right") for each
outstanding share of common stock. Under certain circumstances, a Right may be
exercised to purchase one-thousandth of a share of Series A preferred stock at
an exercise price of $150. The Rights become exercisable if a person acquires
15% or more of SPC's common stock or announces a tender offer for 15% or more of
SPC's common stock. The Rights may be redeemed by SPC at a price of $0.01 per
Right at any time prior to the tenth day after a 15% position has been acquired.
 
     Upon occurrence of certain events after the Rights become exercisable, each
Right would entitle the Right holder to purchase common stock of SPC or the
acquiring company having a market value of twice the $150 exercise price of the
Right, except that the acquiring person or group and other related holders would
not be able to purchase common stock on these terms. The Rights are non-voting
and expire in 2001.

(6) RESTRUCTURING AND LEASE OBLIGATIONS
 
     During fiscal 1994, 1995 and 1996, SPC recorded restructuring charges of
$7,844,000, $5,930,000 and $1,078,000, respectively. The restructuring charges
represent costs associated with the consolidation of facilities, disposal of
fixed assets and severance and reorganization activities associated with
reductions in work force. As a result of these reorganizations, SPC has
centralized all of its research and development as well as its finance and
manufacturing activities, consolidated its sales and marketing functions and
outsourced to third parties its telesales, support and customer service
activities.
 
     Restructuring charges arising due to the consolidation of facilities
related primarily to the centralization and downsizing of the Santa Clara,
California facilities in fiscal years 1994 and 1995 and SPC's downsizing of its
San Jose, California facilities in fiscal 1996. The reserves for lease
obligations related to excess space at SPC's headquarters and certain sales
office locations includes future rent for the excess space and buy-out payments
for expected early termination of certain leases, net of sublease income. Other
consists of costs associated with discontinued products and professional fees
rendered by outside consultants and legal counsel. In connection with the
restructurings, SPC reduced its work force, which resulted in the write-off of
certain fixed assets at the Santa Clara facility in fiscal 1994 and at the
Bracknell, United Kingdom facility in 1995. SPC also wrote off assets at the
Madison, Wisconsin and Abingdon, United Kingdom facilities in fiscal 1994.
 
     In the second quarter of fiscal 1994, SPC incurred a charge of $7.8 million
which included a charge of $3.9 million for costs associated with reduction in
force and severance and a charge of $3.9 million for excess facilities,
equipment, and professional fees and other. The charges for excess facilities
and equipment were net of expected sublease income and estimated proceeds on the
sale of excess equipment. During the fourth quarter of fiscal 1994, SPC
subleased a significant portion of its Santa Clara, California facility,
resulting in the reversal of $2.6 million of reserves associated with
facilities-related restructuring charges initially recorded in the fourth
quarter of fiscal 1992. The reorganization in the second quarter of fiscal 1994
included the cancellation of future development of the Superbase product line,
which was sold in the third quarter of fiscal 1994. See Note 12.
 
     In the third quarter of fiscal 1995, SPC reversed $6.0 million in prior
period restructuring charges upon the negotiated termination of the lease on its
headquarters facility. In the fourth quarter of fiscal 1995, SPC incurred a
restructuring charge of $5.9 million, which included $1.4 million for reduction
in worldwide work force and severance and $4.5 million for excess facilities,
equipment, and product discontinuation and other.
 
     In the second quarter of fiscal 1996, SPC reversed $0.65 million in prior
period restructuring charges upon the negotiated sublease of a portion of its
facilities located in Bracknell, United Kingdom. In the fourth quarter of fiscal
1996, SPC incurred a restructuring charge of $1.1 million, which included $0.2
million for reduction in worldwide work force and severance and $0.9 million for
excess facilities, product discontinuation and other.
 
     As of September 30, 1996, expected cash payments, including taxes,
insurance and maintenance for SPC's accrued lease obligations, net of expected
sublease income, are $745,000 in fiscal year 1997; although other payment terms
may be negotiated with the lessors.

</TABLE>
 
     For the three fiscal years ended September 30, 1994, 1995 and 1996, SPC
established a valuation allowance for deferred tax assets, as realizability was
not sufficiently likely. If SPC generates taxable income in the U.S. in future
years, the valuation allowance may be reduced, which correspondingly may reduce
SPC's tax provision.
 
     At September 30, 1996, SPC has approximately $69 million of federal net
operating loss carryforwards which expire through 2011. The utilization of SPC's
net operating loss and credit carryforwards may be impaired or reduced under
certain circumstances. Events which may affect these carryforwards include, but
are not limited to, cumulative ownership changes of more than 50% over a three
year period, as defined by the Internal Revenue Code of 1986 and related
regulations. See Note (11).
 
(8) LITIGATION
 
     SPC is a defendant in certain litigation. Management is of the opinion that
the ultimate outcome of the litigation will not have a material effect on the
future operations or financial condition of SPC.

     In fiscal 1994, SPC resolved certain litigation between SPC and a purchaser
of one of SPC's product lines, resulting in SPC receiving an arbitration award
of $2.6 million. SPC also sold at such time certain stock previously received
from such purchaser, resulting in income of $3.4 million.
 
(9) SEGMENT AND GEOGRAPHIC INFORMATION
 
     SPC conducts its business within one industry segment, which is the
development, marketing and support of personal computer software. In fiscal
1994, one customer represented 22% of total net revenues. In fiscal 1995, one
customer represented 31% of total net revenues and 46% of net outstanding
accounts receivable at September 30, 1995. In fiscal 1996, one customer
represented 19% of total net revenues and 38% of net outstanding accounts
receivable as of September 30, 1996.
 
     Net revenues from customers outside of North America amounted to
$20,552,000 or 33% of total net revenues, $11,320,000 or 36% and $4,385,000 or
34% in fiscal years 1994, 1995, and 1996, respectively. Sales and marketing
operations outside of North America are conducted principally through
international sales subsidiaries. Most of the international assets are located
in the United Kingdom. Fiscal 1994, 1995 and 1996 financial information by
geographical region is summarized below (in thousands):

(10) COMMITMENTS AND CONTINGENCIES
 
     SPC leases its office facilities under noncancelable leases expiring in
December 2000. During fiscal 1995, SPC entered into a new lease effective
January 1996 for its headquarters location in San Jose, California. This lease
includes two options to extend the lease, each for an additional two-year term,
and an option to terminate a portion or the entire lease any time after December
1998. As of October 1, 1996, in conjunction with SPC's reduction in force, SPC
surrendered a portion of the original leased premises.

(11) ACQUISITIONS, MERGERS, AND DIVESTITURES
 
  Sale of Superbase Product Line
 
     In June 1994, SPC sold its Superbase product line to Computer Concepts
Corporation ("CCC") for 2,031,175 shares of the CCC's restricted common stock.
As part of such sale, CCC agreed to issue additional shares to SPC if CCC failed
to register such shares with the Securities and Exchange Commission for resale
by SPC within certain time periods or, in certain circumstances, if SPC realized
less than a specified price upon such resale. In September 1996, CCC and SPC
entered into a binding letter of intent, pursuant to which CCC agreed to pay SPC
$619,420 and issue to SPC 1,064,667 additional shares of CCC common stock as
penalties for late registration. In October 1996, SPC and CCC entered into a
definitive settlement agreement, reflecting the same terms and conditions,
including additional release of claims provisions, and SPC received the
foregoing cash and shares. As of September 30, 1996, SPC had sold 588,195 shares
of CCC common stock for a gain of $0.6 million. As of October 21, 1996, SPC sold
an additional 674,000 shares. It is anticipated that SPC will attempt to sell
the remaining CCC shares, approximately 1.8 million, over the next three fiscal
quarters. As of September 30, 1996, the closing price of the CCC common stock on
the Nasdaq National Market was $0.59.
 
  Acquisition of Digital Paper
 
     SPC acquired Digital Paper, a developer of visual communications software
technology, during the second quarter of fiscal 1995 for approximately $5.0
million in cash and stock in installment payments and up to an additional $1.5
million in cash upon the achievement of certain unit, revenue and technical
milestones over the next three years. As a result of this acquisition, SPC
recorded a one time charge of $4.8 million in the second quarter of fiscal 1995
for the portion of the transaction related to in-process research and
development. SPC expenses the milestone payments at the time of payment. As of
September 30, 1996, SPC has paid $3.65 million in installment payments and paid
milestone payments totaling $1.0 million.
 
  Merger With Allegro New Media, Inc.
 
     In October 1996, SPC announced that it had entered into a definitive merger
agreement with Allegro New Media, Inc. ("Allegro"). Under the terms of the
agreement, SPC will become a wholly-owned subsidiary of Allegro and will
continue to operate under the name of Software Publishing Corporation. As a
result of the merger, SPC's stockholders will receive approximately 0.26805
shares of Allegro common stock for each share of SPC's stock. Following the
merger, SPC's stockholders and vested option holders will hold

approximately 43% of the outstanding shares of Allegro. The transaction is
structured to qualify as a tax-free reorganization and will be accounted for
under the purchase method of accounting. The transaction will also trigger the
change in ownership limitation on utilization of SPC's net operating loss carry
forwards discussed in Note 7.
 
     The boards of directors of both companies have unanimously approved the
definitive merger agreement. The merger is subject to the approval of both
companies' stockholders and other customary conditions to closing. Subject to
regulatory approval, the parties currently anticipate to close the transaction
on or about December 31, 1996.
 
     The SPC Board of Directors also approved the lending of up to $1.0 million
to Allegro pursuant to the terms of the proposed Agreement.

1. BASIS OF PRESENTATION
 
     The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information and with the instructions to Form 10-QSB and
Article 310 of Regulation S-B. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation have been included. Operating results for the three month and nine
month periods ended September 30, 1996 are not necessarily indicative of the
results that may be expected for the year ended December 31, 1996. For further
information, refer to the consolidated financial statements and footnotes
thereto included in the Company's annual report on Form 10-KSB and Form 10-KSB/A
for the year ended December 31, 1995.
 
2. LOSS PER SHARE
 
     Net loss per share is computed based upon the weighted average number of
shares of common stock and common share equivalents outstanding during the
periods presented. In accordance with the Securities and Exchange Commission
Staff Accounting Bulletin No. 83, shares issuable upon exercise of options
granted during the twelve months immediately preceding the initial public
offering have been included in the calculation of shares used in computing net
loss per share as if they were outstanding for all periods presented using the
treasury stock method. For the period subsequent to the initial public offering,
common share equivalents resulting from outstanding options to purchase common
stock are excluded as the impact is anti-dilutive.
 
3. INVENTORIES
 
     Inventories consist of the following:

4. SHAREHOLDER'S EQUITY
 
     During 1994 the Company issued an aggregate of 1,190,250 shares of its
Class A Cumulative, Convertible, Redeemable 10% Preferred Stock ("Redeemable
Preferred Stock") in a private placement transaction. In accordance with its
terms, all of the shares of Redeemable Preferred Stock were converted into an
aggregate of 491,821 shares of the Company's common stock upon completion of the
Company's initial public offering in December 1995. No dividends were declared
or paid on the Redeemable Preferred Stock.
 
     In connection with certain financing transactions during 1993, certain of
the then existing employee/ stockholders of the Company agreed to place an
aggregate of 1,000,000 newly issued shares of the Company's common stock into
escrow. Under the terms of the escrow agreement such shares are to be released
to the stockholders based upon the Company achieving certain financial results,
as defined. When such escrowed shares are released, Securities and Exchange
Commission rules require recognition by the Company of compensation expense
based on the fair value of the shares at the date of release. The escrow
agreement expires the earlier of the release of all of the escrow shares or June
30, 1999. Any shares not released are to be returned to the Company. During
1994, with the approval of such stockholders, 677,500 of these escrowed shares
were canceled.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
     On March 31, 1995, certain existing stockholder employees surrendered to
the Company a total of 280,000 shares of the Company's common stock and agreed
to place an additional 220,000 shares under the terms of an additional escrow
agreement. These shares are to be released to the stockholders upon the Company
attaining certain financial results, as defined. Release of these shares results
in recognition of compensation expense based on the fair value of the shares at
the date of release.
 
     In December 1995, the Company completed an initial public offering of
1,033,000 shares of its common stock and received net proceeds of $4,156,411.
Upon the completion of the offering the Company repaid all of its 10% notes
payable and in addition issued 243,902 shares of its common stock to the former
note holders pursuant to the terms of their subscription. On January 23, 1996
the Company issued 109,400 shares of common stock to its underwriter, upon the
underwriter's exercise of its over-allotment option, and received net proceeds
of $464,907.
 
     On April 26, 1996, upon the execution of and delivery by the Company of a
letter of intent to acquire all of the issued and outstanding capital stock of
Serif Inc. and Serif (Europe) Limited, 217,000 shares of Common Stock held in
escrow pursuant to the above described arrangements were released from escrow
and delivered to the two stockholder employees. In connection with this release
of escrow shares, the Company recorded compensation expense of $637,980. On
September 5, 1996, in recognition of the performance of the Company's management
team, the Board of Directors released 314,000 shares of Common Stock held in
escrow pursuant to the above described arrangements and authorized such shares
to be delivered to the two stockholder employees, and the remaining 11,500
shares held in escrow were canceled. In connection with this release of escrow
shares, the Company recorded compensation expense of $2,135,200. There are no
shares remaining in escrow.
 
     In May 1996, the company issued 17,273 shares of common stock, which had an
aggregate value of $95,000, as part compensation for the acquisition of
software.
 
     On July 31, 1996 the Company issued 1,000,000 shares of common stock upon
the completion of the acquisition of Serif Inc. and Serif (Europe) Limited. In
addition, the Company issued 14,181 shares of common stock to its investment
banker as partial payment for services rendered in conjunction with the
acquisition of Serif Inc. and Serif (Europe) Limited.
 
     On September 18, 1996 the Company granted to M.S. Farrell & Co. ("MSF") and
a designee thereof warrants to purchase 500,000 shares of common stock at an
exercise price of $6.875, which approximated current market value. These
warrants have a term of six years. In exchange for these warrants the Company
received a waiver of certain cash compensation and consulting fees payable by
the Company to MSF as well as the right to pay in cash or common stock, valued
at time of payment, MSF's fee to terminate its exclusive investment banking
relationship, right of first refusal with respect to future financing
transactions, right to certain merger and acquisition fees and financial
consultant fees. The Company ascribed a value of $100,000 to these warrants and
recorded a charge to current operations for this amount. In addition to the
grant of warrants, the Company extended the expiration date of MSF's 103,300
underwriter warrants to purchase shares of common stock at an exercise price of
$6.15 per share to August 20, 2002.
 
5. BUSINESS COMBINATION
 
     On July 31, 1996, Allegro New Media, Inc. (the "Company") acquired all of
the outstanding common stock of Serif, Inc. and all of the outstanding preferred
and common stock of Serif (Europe) Ltd. (collectively "Serif".) The aggregate
purchase price was approximately $5,300,000. The acquisition has been accounted
for as a purchase and the results of operations of Serif are included in the
Company's consolidated financial statements beginning August 1, 1996. Under the
purchase method of accounting, the assets and liabilities have been adjusted to
their preliminary estimated fair values based upon available information and are
subject to revision. As a result of the preliminary purchase price allocation, a

6. SUBSEQUENT EVENTS.
 
     On October 1, 1996, the Company announced that it had entered into a
definitive merger agreement with Software Publishing Corporation (NASDAQ: SPCO).
Under the terms of the agreement, Software Publishing Corporation ("SPC") will
become a wholly-owned subsidiary of the Company and SPC stockholders will
receive approximately 0.26805 shares of the Company's common stock for each
share of SPC stock. In connection with this transaction, SPC has agreed to
provide a loan to the Company of $1,000,000. The merger requires the approval of
the shareholders of SPC. Following the merger, SPC stockholders will hold
approximately 43% of the outstanding shares of Allegro. The acquisition will be
accounted for under the purchase method of accounting. In connection with this
transaction, the Company will file a registration statement with the Securities
and Exchange Commission to register the shares of its common stock to be
exchanged.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Business/Concentration of Credit Risk
 
     Serif, Inc. (the "Company"), develops and publishes a line of desktop
publishing software products. The Company sells its products directly to
customers on a telemarketing basis and to distributors and other re-sellers in
the United States and Canada. The Company performs periodic credit evaluations
of its customers but generally does not require collateral. No individual
customer represents a significant percentage of sales.
 
  Revenue Recognition
 
     Revenue is generally recognized upon shipment of products to customers and
is recorded net of allowances for anticipated returns. Certain customers are
provided goods on a consignment basis. Revenues on these transactions are
recognized upon the sale of products to the ultimate customer.
 
     Revenues from the licensing of proprietary software are recognized upon
delivery, in accordance with the contract terms.
 
  Cash Equivalents
 
     Cash equivalents consist of highly liquid investments with a maturity of
three months or less when purchased.
 
  Inventories
 
     Inventories are stated at the lower of cost (first-in, first-out) or
market.
 
  Product Development Costs
 
     Product development costs consist principally of compensation to employees,
related costs paid to outside consultants and an affiliated company, and
technology and software the Company may acquire for use in its products. All
product development costs are expensed as incurred.
 
  Equipment, Furniture and Leasehold Improvements
 
     Equipment, furniture and leasehold improvements, including assets under
capitalized leases are stated at cost. Depreciation, including amortization of
assets under capitalized leases is provided on a straight-line basis based upon
the estimated useful lives of the related assets, generally 3 to 7 years.
Leasehold improvements are amortized on a straight-line basis over the shorter
of the life of the improvement or the remainder of the lease term.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principals requires management to make estimates and
assumptions that affect the reported amounts in the financial statements and
accompanying notes. These estimates principally include provisions for sales,
returns and allowances. Actual results could differ from these entries.
 
  Interim Financial Statements
 
     The accompanying unaudited interim financial statements as of June 30, 1996
and for each of the six month periods ended June 30, 1996 and 1995 include all
adjustments which, in the opinion of management, are necessary for a fair
presentation of the Company's financial position and results of operations and
cash flows for the periods presented. All such adjustments are of a normal
recurring nature. The results of the Company's operations for the six months
ended June 30, 1996 are not necessarily indicative of the results of operations
for a full fiscal year.

                                  (UNAUDITED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Business/Concentration of Credit Risk
 
     Serif (Europe) Limited (the "Company"), develops and publishes a line of
desktop publishing software products. The Company sells its products directly to
customers on a telemarketing basis and to distributors and other re-sellers in
the United Kingdom and continental Europe. The Company performs periodic credit
evaluations of its customers but generally does not require collateral. No
individual customer represents a significant percentage of sales.
 
  Revenue Recognition
 
     Revenue is generally recognized upon shipment of products to customers and
is recorded net of allowances for anticipated returns. Certain customers are
provided goods on a consignment basis. Revenues on these transactions are
recognized upon the sale of products to the ultimate customer.
 
     Revenues from the licensing of proprietary software are recognized upon
delivery, in accordance with the contract terms.
 
  Cash Equivalents
 
     Cash equivalents consist of highly liquid investments with a maturity of
three months or less when purchased.
 
  Inventories
 
     Inventories are stated at the lower of cost (first-in, first-out) or net
realiseable value. Finished goods include the relevant proportion of overheads.
Net realiseable value is based on estimated selling price less further costs to
completion and disposal.
 
  Product Development Costs
 
     Product development costs consist principally of compensation to employees,
related costs paid to outside consultants and an affiliated company, and
technology and software the Company may acquire for use in its products. All
product development costs are expensed as incurred.
 
  Equipment, Furniture and Leasehold Improvements
 
     Equipment, furniture and leasehold improvements, are stated at cost less
estimated residual values over their estimated useful lives. Depreciation is
provided on a straight-line basis based upon the estimated useful lives of the
related assets, generally 3 to 7 years. Leasehold improvements are amortized on
a straight-line basis over the shorter of the life of the improvement or the
remainder of the lease term.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with United Kingdom
generally accepted accounting principles and with United States generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts in the financial statements and
accompanying notes. These estimates principally include provisions for sales
returns and allowances. Actual results could differ from these estimates.

and subject thereto, at the Effective Time all the property, rights, privileges,

as in effect immediately prior to the Effective Time, shall be the Certificate
of Incorporation of the Surviving Corporation until thereafter amended as

Corporation shall be amended so that the name of the Surviving Corporation shall
be "Software Publishing Corporation."
 
     (b) The Bylaws of Merger Sub, as in effect immediately prior to the
Effective Time, shall be, at the Effective Time, the Bylaws of the Surviving

     1.6 Effect on Capital Stock.  At the Effective Time, by virtue of the
Merger and without any action on the part of Merger Sub, SPC or the holders of
any of the following securities:
 
     (a) Conversion of SPC Capital Stock.  Each share of Common Stock, par value
$.001 per share, of SPC (the "SPC Capital Stock") issued and outstanding
immediately prior to the Effective Time (other than any shares of SPC Capital
Stock to be canceled pursuant to Section 1.6(b) and any Dissenting Shares (as
defined in and to the extent provided in Section 1.7(a)) will be canceled and
extinguished and automatically converted (subject to Sections 1.6(e) and (f))
into the right to receive 0.26805 (the "Exchange Ratio") shares of Common Stock,
par value $.001 per share, of Allegro (the "Allegro Common Stock") upon
surrender of the certificate representing such share of SPC Capital Stock in the
manner provided in Section 1.8 (or in the case of a lost, stolen or destroyed
certificate, upon delivery of an affidavit (and bond, if required) in the manner
provided in Section 1.10).
 
     (b) Cancellation of Allegro-Owned Stock.  Each share of SPC Capital Stock
held in the treasury of SPC or owned by Merger Sub, Allegro or any direct or
indirect wholly owned subsidiary of SPC or of Allegro immediately prior to the
Effective Time shall be canceled and extinguished without any conversion
thereof.
 
     (c) Stock Options.  At the Effective Time all options to purchase SPC
Capital Stock then outstanding under SPC's 1987 Stock Option Plan, 1989 Stock
Option Plan, and 1991 Stock Option Plan (collectively, the "SPC Stock Option
Plans") shall be assumed by Allegro in accordance with Section 5.11 hereof.
 
     (d) Employee Stock Purchase Plan.  With respect to the Company's Employee
Stock Purchase Plan (the "SPC Employee Stock Purchase Plan"), the offering

immediately following the purchase of SPC Capital Stock on the New Exercise
Date.
 
     (e) Capital Stock of Merger Sub.  Each share of Common Stock, par value
$.001 per share, of Merger Sub issued and outstanding immediately prior to the
Effective Time shall be converted into and exchanged for one validly issued,
fully paid and nonassessable share of Common Stock, par value $.001 per share,
of the Surviving Corporation. Each stock certificate of Merger Sub evidencing
ownership of any such shares shall continue to evidence ownership of such shares
of capital stock of the Surviving Corporation.
 
     (f) Adjustments to Exchange Ratio.  The Exchange Ratio shall be adjusted to
reflect fully the effect of any stock split, reverse stock split, stock dividend
(including any dividend or distribution of securities convertible into Allegro
Common Stock or SPC Capital Stock), reorganization, recapitalization or other
like change with respect to Allegro Common Stock or SPC Capital Stock occurring
on or after the date hereof and prior to the Effective Time.

<PAGE>   195
 
     (g) Fractional Shares.  No fraction of a share of Allegro Common Stock will
be issued by virtue of the Merger, but in lieu thereof each holder of shares of
SPC Capital Stock who would otherwise be entitled to a fraction of a share of
Allegro Common Stock (after aggregating all fractional shares of Allegro Common
Stock to be received by such holder) shall receive from Allegro an amount of
cash (rounded to the nearest whole cent) equal to the product of (i) such
fraction, multiplied by (ii) the average closing price of a share of Allegro
Common Stock for the ten most recent days that Allegro Common Stock has traded
ending on the trading day immediately prior to the Effective Time, as reported
on the Nasdaq SmallCap Market.
 
     1.7 Dissenting Shares.
 
     (a) Notwithstanding any provision of this Agreement to the contrary, the
shares of any holder of SPC Capital Stock who has demanded and perfected
appraisal rights for such shares in accordance with Delaware Law and who, as of
the Effective Time, has not effectively withdrawn or lost such appraisal rights
("Dissenting Shares") shall not be converted into or represent a right to
receive Allegro Common Stock pursuant to Section 1.6, but the holder thereof
shall only be entitled to such rights as are granted by Delaware Law.
 
     (b) Notwithstanding the foregoing, if any holder of shares of SPC Capital
Stock who demands appraisal of such shares under Delaware Law shall effectively
withdraw the right to appraisal, then, as of the later of the Effective Time and
the occurrence of such event, such holder's shares shall automatically be
converted into and represent only the right to receive Allegro Common Stock,
without interest thereon, upon surrender of the certificate representing such
shares.
 
     (c) SPC shall give Allegro (i) prompt notice of any written demands for
appraisal of any shares of SPC Capital Stock, withdrawals of such demands, and
any other instruments served pursuant to Delaware Law and received by SPC which
relate to any such demand for appraisal and (ii) the opportunity to participate
in all negotiations and proceedings which take place prior to the Effective Time
with respect to demands for appraisal under Delaware Law. SPC shall not, except
with the prior written consent of Allegro or as may be required by applicable
law, voluntarily make any payment with respect to any demands for appraisal of
SPC Capital Stock or offer to settle or settle any such demands.
 
     1.8 Surrender of Certificates.
 
     (a) Exchange Agent.  Allegro shall select American Stock Transfer and Trust
Company or another institution reasonably satisfactory to SPC to act as the
exchange agent (the "Exchange Agent") in the Merger.
 
     (b) Allegro to Provide Common Stock.  Promptly after the Effective Time,
Allegro shall make available to the Exchange Agent for exchange in accordance
with this Article I, the shares of Allegro Common Stock issuable pursuant to
Section 1.6 in exchange for outstanding shares of SPC Capital Stock, and cash in
an amount sufficient for payment in lieu of fractional shares pursuant to
Section 1.6(f) and any dividends or distributions and holders of shares of SPC
Capital Stock may be entitled pursuant to Section 1.8(d).
 
     (c) Exchange Procedures.  Promptly after the Effective Time, Allegro shall
cause the Exchange Agent to mail to each holder of record (as of the Effective
Time) of a certificate or certificates (the "Certificates") which immediately
prior to the Effective Time represented outstanding shares of SPC Capital Stock
whose shares were converted into the right to receive shares of Allegro Common
Stock pursuant to Section 1.6, cash in lieu of any fractional shares pursuant to
Section 1.6(f) and any dividends or other distributions pursuant to Section
1.8(d), (i) a letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
delivery of the Certificates to the Exchange Agent and shall be in such form and
have such other provisions as Allegro may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing shares of Allegro
 
                                       A-3
<PAGE>   196

surrender of a Certificate for cancellation to the Exchange Agent or to such
other agent or agents as may be appointed by Allegro, together with such letter
of transmittal, duly completed and validly executed in accordance with the
instructions thereto, the holder of such Certificate shall be entitled to
receive in exchange therefor a certificate representing the number of whole
shares of Allegro Common Stock, payment in lieu of fractional shares which such
holder has the right to receive pursuant to Section 1.6(f) and any dividends or
distributions payable pursuant to Section 1.8(d), and the Certificate so
surrendered shall forthwith be canceled. Until so surrendered, each outstanding
Certificate will be deemed from and after the Effective Time, for all corporate
purposes, subject to Section 1.8(d) as to the payment of dividends, to evidence
the ownership of the number of full shares of Allegro Common Stock into which
such shares of SPC Capital Stock shall have been so converted and the right to
receive an amount in cash in lieu of the issuance of any fractional shares in
accordance with Section 1.6(f) and any dividends or distributions payable
pursuant to Section 1.8(d).
 
     (d) Distributions With Respect to Unexchanged Shares.  No dividends or
other distributions declared or made after the date of this Agreement with
respect to Allegro Common Stock with a record date after the Effective Time will
be paid to the holder of any unsurrendered Certificate with respect to the
shares of Allegro Common Stock represented thereby until the holder of record of
such Certificate shall surrender such Certificate. Subject to applicable law,
following surrender of any such Certificate, there shall be paid to the record
holder thereof certificates representing whole shares of Allegro Common Stock
issued in exchange therefor, without interest, along with the amount of
dividends or other distributions with a record date after the Effective Time
payable with respect to such whole shares of Allegro Common Stock.
 
     (e) Transfers of Ownership.  If any certificate for shares of Allegro
Common Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that the Certificate so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Allegro or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for shares of
Allegro Common Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of Allegro or any
agent designated by it that such tax has been paid or is not payable.
 
     (f) No Liability.  Notwithstanding anything to the contrary in this Section
1.8, neither the Exchange Agent, Allegro, the Surviving Corporation nor any
party hereto shall be liable to a holder of shares of Allegro Common Stock or
SPC Capital Stock for any amount properly paid to a public official pursuant to
any applicable abandoned property, escheat or similar law.
 
     1.9 No Further Ownership Rights in SPC Capital Stock.  All shares of
Allegro Common Stock issued upon the surrender for exchange of Certificates in
accordance with the terms hereof (including any cash paid in respect thereof
pursuant to Section 1.6(f) and 1.8(d)) shall be deemed to have been issued in
full satisfaction of all rights pertaining to such shares of SPC Capital Stock,
and there shall be no further registration of transfers on the records of the
Surviving Corporation of shares of SPC Capital Stock which were outstanding
immediately prior to the Effective Time. If after the Effective Time,
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Article I.
 
     1.10 Lost, Stolen or Destroyed Certificates.  In the event any Certificates
shall have been lost, stolen or destroyed, the Exchange Agent shall issue in
exchange for such lost, stolen or destroyed Certificates, upon the making of an
affidavit of that fact by the holder thereof, such whole number of shares of
Allegro Common Stock into which the shares of SPC Capital Stock evidenced
thereby shall have been converted, cash for fractional shares, if any, as may be
required pursuant to Section 1.6(f) and any dividends or distributions payable
pursuant to Section 1.8(d); provided, however, that Allegro may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed Certificates to deliver a bond in such
sum as it may reasonably direct as indemnity against any claim that may be made
against Allegro or the Exchange Agent with respect to the Certificates alleged
to have been lost, stolen or destroyed.

     1.11 Tax and Accounting Consequences.  It is intended by the parties hereto
that the Merger shall constitute a reorganization within the meaning of Section
368 of the Code. The parties hereto adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Income Tax Regulations.
 
     1.12 Taking of Necessary Action; Further Action.  If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of SPC and Merger Sub, the officers and directors of SPC and
Merger Sub are fully authorized in the name of their respective corporations or
otherwise to take, and will take, all such lawful and necessary action, so long
as such action is consistent with this Agreement.
 
                                   ARTICLE II
 
                     REPRESENTATIONS AND WARRANTIES OF SPC
 
     SPC represents and warrants to Allegro and Merger Sub, subject to the
exceptions specifically disclosed in writing in the disclosure letter supplied
by SPC to Allegro (the "SPC Schedules"), as follows:
 
     2.1 Organization of SPC.  SPC and each of its material subsidiaries is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation, has the corporate power to own, lease
and operate its property and to carry on its business as now being conducted and
as proposed to be conducted, and is duly qualified to do business and in good
standing as a foreign corporation in each jurisdiction in which the failure to
be so qualified would have a Material Adverse Effect (as defined below) on SPC.
SPC has delivered to Allegro a true and complete list of all of SPC's
subsidiaries, together with the jurisdiction of incorporation of each subsidiary
and SPC's equity interest therein. SPC has delivered or made available a true
and correct copy of the Certificate of Incorporation and Bylaws of SPC and
similar governing instruments of its subsidiaries, each as amended to date, to
counsel for Allegro. When used in connection with SPC, the term "Material
Adverse Effect" means, for purposes of this Agreement, any change, event or
effect that is materially adverse to the business, assets (including intangible
assets), financial condition or results of operations of SPC and its
subsidiaries taken as a whole; provided, however, that the continuation of
current trends in such business, assets (including intangible assets), financial
condition or results of operations (including without limitation declining
revenues and further losses) shall not be deemed to constitute a Material
Adverse Effect, but material deviations therefrom shall constitute a Material
Adverse Effect.
 
     2.2 SPC Capital Structure.  The authorized capital stock of SPC consists of
30,000,000 shares of Common Stock, par value $.001 per share, of which there
were 12,553,596 shares issued and outstanding as of October 1, 1996, and
2,000,000 shares of Preferred Stock, par value $.001 per share, none of which
are issued and outstanding as of October 1, 1996. All outstanding shares of SPC
Capital Stock are duly authorized, validly issued, fully paid and non-assessable
and are not subject to preemptive rights created by statute, the Certificate of
Incorporation or Bylaws of SPC or any agreement or document to which SPC is a
party or by which it is bound. As of October 1, 1996, SPC had reserved an
aggregate of 3,187,760 shares of Common Stock, net of exercises, for issuance to
employees, consultants and non-employee directors pursuant to the SPC Stock
Option Plans, under which options are outstanding for an aggregate of 3,018,725
shares. All shares of SPC Capital Stock subject to issuance as aforesaid, upon
issuance on the terms and conditions specified in the instruments pursuant to
which they are issuable, would be duly authorized, validly issued, fully paid
and nonassessable. The SPC Schedules list each outstanding option to acquire
shares of the Common Stock of SPC at October 1, 1996, the name of the holder of
such option, the number of shares subject to such option, the exercise price of
such option, the number of shares as to which such option will have vested at
such date and whether the exercisability of such option will be accelerated in
any way by the transactions contemplated by this Agreement or for any other
reason, and indicate the extent of acceleration, if any. As of September 15,
1996, there were 10 participants in the SPC Employee Stock Purchase Plan.

     2.3 Obligations With Respect to Capital Stock.  Except as set forth in
Section 2.2, there are no equity securities of any class of SPC, or any
securities exchangeable or convertible into or exercisable for such equity
securities, issued, reserved for issuance or outstanding. Except for securities
SPC owns, directly or indirectly through one or more subsidiaries, there are no
equity securities of any class of any subsidiary of SPC, or any security
exchangeable or convertible into or exercisable for such equity securities,
issued, reserved for issuance or outstanding. Except as set forth in Section
2.2, there are no options, warrants, equity securities, calls, rights (including
preemptive rights), commitments or agreements of any character to which SPC or
any of its subsidiaries is a party or by which it is bound obligating SPC or any
of its subsidiaries to issue, deliver or sell, or cause to be issued, delivered
or sold, or repurchase, redeem or otherwise acquire, or cause the repurchase,
redemption or acquisition, of any shares of capital stock of SPC, or any of its
subsidiaries or obligating SPC or any of its subsidiaries to grant, extend,
accelerate the vesting of or enter into any such option, warrant, equity
security, call, right, commitment or agreement. There are no registration rights
and, to the knowledge of SPC, there are no voting trusts, proxies or other
agreements or understandings with respect to any equity security of any class of
SPC or with respect to any equity security of any class of any of its
subsidiaries.
 
     2.4 Authority.
 
     (a) SPC has all requisite corporate power and authority to enter into this
Agreement and to consummate the transactions contemplated hereby. The execution
and delivery of this Agreement and the consummation of the transactions
contemplated hereby, have been duly authorized by all necessary corporate action
on the part of SPC, subject only to the approval of this Agreement by SPC's
stockholders and the filing and recordation of the Certificate of Merger
pursuant to Delaware Law. A vote of the holders of at least a majority of the
outstanding shares of the SPC Capital Stock is required for SPC's stockholders
to approve this Agreement. This Agreement has been duly executed and delivered
by SPC and, assuming the due authorization, execution and delivery by Allegro
and, if applicable, Merger Sub, constitutes the valid and binding obligation of
SPC, enforceable in accordance with its terms, except as enforceability may be
limited by bankruptcy and other similar laws and general principles of equity.
The execution and delivery of this Agreement by SPC does not, and the
performance of this Agreement by SPC will not, (i) conflict with or violate the
Certificate of Incorporation or Bylaws of SPC or the equivalent organizational
documents of any of its subsidiaries, (ii) subject to obtaining the approval of
SPC's stockholders of the Merger as contemplated in Section 5.2 and compliance
with the requirements set forth in Section 2.4(b) below, conflict with or
violate any law, rule, regulation, order, judgment or decree applicable to SPC
or any of its subsidiaries or by which its or any of their respective properties
is bound or affected, or (iii) result in any breach of or constitute a default
(or an event that with notice or lapse of time or both would become a default)
under, or impair SPC's rights or alter the rights or obligations of any third
party under, or give to others any rights of termination, amendment,
acceleration or cancellation of, or result in the creation of a lien or
encumbrance on any of the properties or assets of SPC or any of its subsidiaries
pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease,
license, permit, franchise or other instrument or obligation to which SPC or any
of its subsidiaries is a party or by which SPC or any of its subsidiaries or its
or any of their respective properties are bound or affected, except, with
respect to clauses (ii) and (iii), for any such conflicts, violations, defaults
or other occurrences that would not have a Material Adverse Effect on SPC. The
SPC Schedules list all material consents, waivers and approvals under any of
SPC's or any of its subsidiaries' agreements, contracts, licenses or leases
required to be obtained in connection with the consummation of the transactions
contemplated hereby.
 
     (b) No consent, approval, order or authorization of, or registration,
declaration or filing with any court, administrative agency or commission or
other governmental authority or instrumentality ("Governmental Entity") is
required by or with respect to SPC in connection with the execution and delivery
of this Agreement or the consummation of the transactions contemplated hereby or
thereby, except for (i) the filing of a Form S-4 Registration Statement (the
"Registration Statement") with the Securities and Exchange Commission ("SEC") in
accordance with the Securities Act of 1933, as amended (the "Securities Act"),
(ii) the filing of the Certificate of Merger with the Secretary of State of the
State of Delaware, (iii) the filing of the Proxy Statement (as defined in
Section 2.20) with the SEC in accordance with the Securities Exchange Act of
1934, as amended (the "Exchange Act"), (iv) the filing of a Current Report on
Form 8-K with the
 
                                       A-6
<PAGE>   199
 
SEC, (v) such consents, approvals, orders, authorizations, registrations,
declarations and filings as may be required under applicable federal and state
securities laws and the laws of any foreign country and (vi) such other
consents, authorizations, filings, approvals and registrations which, if not
obtained or made, would not have a Material Adverse Effect on SPC or Allegro or
have a material adverse effect on the ability of the parties to consummate the
Merger.
 
     2.5 Section 203 of the Delaware General Corporation Law Not
Applicable.  The Board of Directors of SPC has taken all actions so that the
restrictions contained in Section 203 of the Delaware General Corporation Law
applicable to a "business combination" (as defined in Section 203) will not
apply to the execution, delivery or performance of this Agreement or to the
consummation of the Merger or the other transactions contemplated by this
Agreement.
 
     2.6 SEC Filings; SPC Financial Statements.
 
     (a) SPC has filed all forms, reports and documents required to be filed
with the SEC since October 1, 1994, and has made available to Allegro such
forms, reports and documents in the form filed with the SEC. All such required
forms, reports and documents (including those that SPC may file subsequent to
the date hereof) are referred to herein as the "SPC SEC Reports." As of their
respective dates, the SPC SEC Reports (i) were prepared in accordance with the
requirements of the Securities Act or the Exchange Act, as the case may be, and
the rules and regulations of the SEC thereunder applicable to such SPC SEC
Reports, and (ii) did not at the time they were filed (or if amended or
superseded by a filing prior to the date of this Agreement, then on the date of
such filing) contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. None of SPC's subsidiaries is required to file any forms,
reports or other documents with the SEC.
 
     (b) Each of the consolidated financial statements (including, in each case,
any related notes thereto) contained in SPC SEC Reports (the "SPC Financials"),
including any SPC SEC Reports filed after the date hereof until the Closing, (x)
complied as to form in all material respects with the published rules and
regulations of the SEC with respect thereto, (y) was prepared in accordance with
generally accepted accounting principles ("GAAP") applied on a consistent basis
throughout the periods involved (except as may be indicated in the notes thereto
or, in the case of unaudited interim financial statements, as may be permitted
by the SEC on Form 10-Q under the Exchange Act) and (z) fairly presented the
consolidated financial position of SPC and its subsidiaries as at the respective
dates thereof and the consolidated results of its operations and cash flows for
the periods indicated, except that the unaudited interim financial statements
were or are subject to normal and recurring year-end adjustments which were not,
or are not expected to be, material in amount. The balance sheet of SPC
contained in SPC SEC Reports as of June 30, 1996 is hereinafter referred to as
the "SPC Balance Sheet." Except as disclosed in the SPC Financials, neither SPC
nor any of its subsidiaries has any liabilities (absolute, accrued, contingent
or otherwise) of a nature required to be disclosed on a balance sheet or in the
related notes to the consolidated financial statements prepared in accordance
with GAAP which are, individually or in the aggregate, material to the business,
results of operations or financial condition of SPC and its subsidiaries taken
as a whole, except liabilities (i) provided for in the SPC Balance Sheet, or
(ii) incurred since the date of the SPC Balance Sheet in the ordinary course of
business consistent with past practices.
 
     (c) SPC has heretofore furnished to Allegro a complete and correct copy of
any amendments or modifications, which have not yet been filed with the SEC but
which are required to be filed, to agreements, documents or other instruments
which previously had been filed by SPC with the SEC pursuant to the Securities
Act or the Exchange Act.
 
     2.7 Absence of Certain Changes or Events.  Since the date of the SPC
Balance Sheet through the date of this Agreement, there has not been: (i) any
Material Adverse Effect on SPC, (ii) any material change by SPC in its
accounting methods, principles or practices, except as required by concurrent
changes in GAAP, or (iii) any revaluation by SPC of any of its assets having a
Material Adverse Effect on SPC, including, without limitation, writing down the
value of capitalized software or inventory or writing off notes or accounts
receivable other than in the ordinary course of business.

<PAGE>   200
 
     2.8 Taxes.  SPC and each of its subsidiaries has filed all tax returns
required to be filed by any of them and has paid (or SPC has paid on its
behalf), or has set up an adequate reserve for the payment of, all material
taxes required to be paid as shown on such returns, and the most recent
financial statements contained in the SPC SEC Reports reflect an adequate
reserve for all material taxes payable by SPC and its subsidiaries accrued
through the date of such financial statements. Except as reasonably would not be
expected to have a Material Adverse Effect on SPC, no deficiencies for any taxes
have been proposed, asserted or assessed against SPC or any of its subsidiaries.
For the purpose of this Agreement, the term "tax" shall include all Federal,
state, local and foreign income, profits, franchise, gross receipts, payroll,
sales, employment, use, property, withholding, excise and other taxes, duties or
assessments of any nature whatsoever, together with all interest, penalties and
additions imposed with respect to such amounts.
 
     2.9 Intellectual Property.
 
     (a) To the knowledge of SPC and its subsidiaries, SPC and its subsidiaries
own, or have the right to use, sell or license all patents, trademarks, trade
names, service marks, copyrights and other intellectual property necessary or
required for the conduct of their respective businesses as presently conducted
(such intellectual property and the rights thereto are collectively referred to
herein as the "SPC IP Rights"), except for any failure to own or have the right
to use, sell or license that would not have a Material Adverse Effect on SPC;
provided, that the foregoing exception shall not apply to the SPC IP Rights with
respect to "Intelligent Formatting".
 
     (b) The execution, delivery and performance of this Agreement and the
consummation of the transactions contemplated hereby will not constitute a
breach of any instrument or agreement governing any SPC IP Rights (the "SPC IP
Rights Agreements"), will not cause the forfeiture or termination or give rise
to a right of forfeiture or termination of any SPC IP Rights or impair the right
of SPC and its subsidiaries, the Surviving Corporation or Allegro to use, sell
or license any SPC IP Rights or portion thereof, except for the occurrence of
any such breach, forfeiture, termination or impairment that would not
individually or in the aggregate, result in a Material Adverse Effect on SPC.
 
     (c) To the knowledge of SPC and its subsidiaries, (i) neither the
manufacture, marketing, license, sale or intended use of any product or
technology currently licensed or sold or under development by SPC or any of its
subsidiaries violates any license or agreement between SPC or any of its
subsidiaries and any third party or infringes any intellectual property right of
any other party; and (ii) there is no pending or, to the knowledge of SPC,
threatened claim, arbitration or litigation contesting the validity, ownership
or right to use, sell, license or dispose of any SPC IP Rights, nor has SPC
received any written notice asserting that any SPC IP Rights or the proposed
use, sale, license or disposition thereof conflicts or will conflict with the
rights of any other party, except, with respect to clauses (i) and (ii), for any
violations, infringements, claims or litigation that would not have a Material
Adverse Effect on SPC.
 
     (d) SPC has taken reasonable and practicable steps designed to safeguard
and maintain the secrecy and confidentiality of, and its proprietary rights in,
all SPC IP Rights.
 
     2.10 Compliance; Permits; Restrictions.
 
     (a) Neither SPC nor any of its subsidiaries is in conflict with, or in
default or violation of, (i) any law, rule, regulation, order, judgment or
decree applicable to SPC or any of its subsidiaries or by which its or any of
their respective properties is bound or affected, or (ii) any note, bond,
mortgage, indenture, contract, agreement, lease, license, permit, franchise or
other instrument or obligation to which SPC or any of its subsidiaries is a
party or by which SPC or any of its subsidiaries or its or any of their
respective properties is bound or affected, except for any conflicts, defaults
or violations which would not have a Material Adverse Effect on SPC. No
investigation or review by any governmental or regulatory body or authority is
pending or, to the knowledge of SPC, threatened against SPC or its subsidiaries,
nor has any governmental or regulatory body or authority indicated an intention
to conduct the same, other than, in each such case, those the outcome of which
would not have a Material Adverse Effect on SPC.
 
     (b) SPC and its subsidiaries hold all permits, licenses, variances,
exemptions, orders and approvals from governmental authorities which are
material to the operation of the business of SPC and its subsidiaries taken
 
                                       A-8
<PAGE>   201
 
as a whole (collectively, the "SPC Permits"). SPC and its subsidiaries are in
compliance with the terms of SPC Permits, except where the failure to hold the
same or to so comply would not have a Material Adverse Effect on SPC.
 
     2.11 Litigation.  There is no action, suit, proceeding, claim, arbitration
or investigation pending, or as to which SPC or any of its subsidiaries has
received any notice of assertion nor, to SPC's knowledge, is there a written
threat of an action, suit, proceeding, claim, arbitration or investigation
against SPC or any of its subsidiaries which would have a Material Adverse
Effect on SPC, or which in any manner challenges or seeks to prevent, enjoin,
alter or delay any of the transactions contemplated by this Agreement.
 
     2.12 Brokers' and Finders' Fees.  Except for fees payable to Unterberg
Harris disclosed to Allegro, SPC has not incurred, nor will it incur, directly
or indirectly, any liability for brokerage or finders' fees or agents'
commissions or any similar charges in connection with this Agreement or any
transaction contemplated hereby.
 
     2.13 Employee Benefit Plans.
 
     (a) With respect to each material employee benefit plan, program,
arrangement and contract (including, without limitation, any "employee benefit
plan" as defined in Section 3(3) of the Employee Retirement Income Security Act
of 1974, as amended ("ERISA")) maintained or contributed to by SPC or any trade
or business (an "ERISA Affiliate") which is under common control with SPC within
the meaning of Section 414 of the Code (the "SPC Employee Plans"), SPC has made
available to Allegro a true and complete copy of, to the extent applicable, (i)
such SPC Employee Plan, (ii) the most recent annual report (Form 5500), (iii)
each trust agreement related to such SPC Employee Plan, (iv) the most recent
summary plan description for each SPC Employee Plan for which such a description
is required, (v) the most recent actuarial report relating to any SPC Employee
Plan subject to Title IV of ERISA and (vi) the most recent United States
Internal Revenue Service ("IRS") determination letter issued with respect to any
SPC Employee Plan.
 
     (b) Each SPC Employee Plan which is intended to be qualified under Section
401(a) of the Code has received a favorable determination from the IRS covering
the provisions of the Tax Reform Act of 1986 stating that such SPC Employee Plan
is so qualified and nothing has occurred since the date of such letter that
could reasonably be expected to affect the qualified status of such plan. Each
SPC Employee Plan has been operated in all material respects in accordance with
its terms and the requirements of applicable law. Neither SPC nor any ERISA
Affiliate of SPC has incurred or is reasonably expected to incur any material
liability under Title IV of ERISA in connection with any SPC Employee Plan.
 
     (c) Neither SPC nor any ERISA Affiliate thereof has withdrawn in a complete
or partial withdrawal from any multi-employer plan within the meaning of Section
4001(a)(3) of ERISA prior to the Effective Time. Neither SPC nor any ERISA
Affiliate thereof has contributed to or been obligated to contribute to any
multi-employer plan within the meaning of Section 4001(a)(3) of ERISA.
 
     2.14 Absence of Liens and Encumbrances.  SPC and each of its subsidiaries
has good and valid title to, or, in the case of leased properties and assets,
valid leasehold interests in, all of its material tangible properties and
assets, real, personal and mixed, used in its business, free and clear of any
liens or encumbrances except as reflected in the SPC Financials and except for
liens for taxes not yet due and payable and such imperfections of title and
encumbrances, if any, which would not have a Material Adverse Effect on SPC.
 
     2.15 Environmental Matters.
 
     (a) Hazardous Material.  Except as would not have a Material Adverse Effect
on SPC, no underground storage tanks and no amount of any substance that has
been designated by any Governmental Entity or by applicable federal, state or
local law to be radioactive, toxic, hazardous or otherwise a danger to health or
the environment, including, without limitation, PCBs, asbestos, petroleum,
urea-formaldehyde and all substances listed as hazardous substances pursuant to

                                       A-9
<PAGE>   202
 
(a "Hazardous Material"), but excluding office and janitorial supplies, are
present in the soil, groundwater, building materials or ambient air of any real
property currently occupied by SPC as a result of the deliberate actions of SPC
or any of its subsidiaries, and SPC has not received any notice that it is
allegedly liable for the presence of Hazardous Materials in, on or under any
other property, including the land and the improvements, ground water and
surface water thereof, that SPC or any of its subsidiaries has at any time
owned, operated, occupied or leased.
 
     (b) Hazardous Materials Activities.  Except as would not have a Material
Adverse Effect on SPC, neither SPC nor any of its subsidiaries has transported,
stored, used, manufactured, disposed of, released or exposed its employees or
others to Hazardous Materials in violation of any law in effect on or before the
Closing Date, nor has SPC or any of its subsidiaries disposed of, transported,
sold, or manufactured any product containing a Hazardous Material (collectively
"Hazardous Materials Activities") in violation of any rule, regulation, treaty
or statute promulgated by any Governmental Entity in effect prior to or as of
the date hereof to prohibit, regulate or control Hazardous Materials or any
Hazardous Material Activity.
 
     (c) Permits.  SPC and its subsidiaries currently hold all environmental
approvals, permits, licenses, clearances and consents (the "SPC Environmental
Permits") necessary for the conduct of SPC's and its subsidiaries' Hazardous
Material Activities as currently conducted and other businesses of SPC and its
subsidiaries as such activities and businesses are currently being conducted,
except where the failure to so hold would not have a Material Adverse Effect on
SPC.
 
     (d) Environmental Liabilities.  No material action, proceeding, revocation
proceeding, amendment procedure, writ, injunction or claim is pending, or to
SPC's knowledge, threatened concerning any SPC Environmental Permit or any
Hazardous Materials Activity of SPC or any of its subsidiaries. SPC is not aware
of any fact or circumstance which could involve SPC or any of its subsidiaries
in any environmental litigation or impose upon SPC or any of its subsidiaries
any environmental liability that would have a Material Adverse Effect on SPC.
 
     2.16 Labor Matters.  To SPC's knowledge, there are no activities or
proceedings of any labor union to organize any employees of SPC or any of its
subsidiaries and there are no strikes, or material slowdowns, work stoppages or
lockouts, or threats thereof by or with respect to any employees of SPC or any
of its subsidiaries. SPC and its subsidiaries are and have been in compliance
with all applicable laws regarding employment practices, terms and conditions of
employment, and wages and hours (including, without limitation, ERISA (as
defined below), WARN or any similar state or local law), except for any
noncompliance that would not have a Material Adverse Effect on SPC.
 
     2.17 Agreements, Contracts and Commitments.  Except as set forth in the SPC

          (a) any collective bargaining agreements;

     profit-sharing or retirement plans, or any other employee benefit plans or
     arrangements;
 
          (c) any employment or consulting agreement, contract or commitment
     with any officer or director level employee, not terminable by SPC or any
     of its subsidiaries on thirty days notice without liability, except to the
     extent general principles of wrongful termination law may limit SPC's or
     any of its subsidiaries, ability to terminate employees at will;
 
          (d) any agreement or plan, including, without limitation, any stock

of the material terms or conditions of any of the agreements, contracts or
commitments to which SPC is a party or by which it is bound of the type
described in clauses (a) through (l) above (any such agreement, contract or
commitment, an "SPC Contract") in such a manner as would permit any other party

seek damages, which would have a Material Adverse Effect on SPC.
 
     2.18 Change of Control Payments.  There are no plans or agreements pursuant
to which any amounts may become payable (whether currently or in the future) to

statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein not
misleading. The information supplied by SPC for inclusion in the proxy

not, on the date the Proxy Statement is first mailed to SPC's stockholders and
Allegro's stockholders, at the time of the SPC Stockholders' Meeting or the
Allegro Stockholders' Meeting and at the Effective Time, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not false or misleading; or omit to
state any material fact necessary to correct any statement in any earlier
communication with respect to the solicitation of proxies for the SPC
Stockholders' Meeting or the Allegro Stockholders' Meeting which has become
false or misleading. The Proxy Statement will comply as to form in all material
respects with the provisions of the Exchange Act and the rules and regulations
thereunder. If at any time prior to the Effective Time, any event relating to
SPC or any of its affiliates, officers or directors should be discovered by SPC
which should be set forth in an amendment to the Registration Statement or a
supplement to the Proxy Statement, SPC shall promptly inform Allegro.
Notwithstanding the foregoing, SPC makes no representation or warranty with
 
                                      A-11

                                  ARTICLE III
 
            REPRESENTATIONS AND WARRANTIES OF ALLEGRO AND MERGER SUB
 
     Allegro and Merger Sub represent and warrant to SPC, subject to the
exceptions specifically disclosed in the disclosure letter supplied by Allegro
to SPC (the "Allegro Schedules"), as follows:
 
     3.1 Organization of Allegro.  Allegro and each of its material subsidiaries
is a corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation, has the corporate power to own,
lease and operate its property and to carry on its business as now being
conducted and as proposed to be conducted, and is duly qualified to do business
and in good standing as a foreign corporation in each jurisdiction in which the
failure to be so qualified would have a Material Adverse Effect (as defined
below) on Allegro. Allegro has delivered to SPC a true and complete list of all
of Allegro's subsidiaries, together with the jurisdiction of incorporation of
each subsidiary and Allegro's equity interest therein. Allegro has delivered or
made available a true and correct copy of the Certificate of Incorporation and
Bylaws of Allegro and similar governing instruments of its subsidiaries, each as
amended to date, to counsel for SPC. When used in connection with Allegro, the
term "Material Adverse Effect" means, for purposes of this Agreement, any
change, event or effect that is materially adverse to the business, assets
(including intangible assets), financial condition or results of operations of
Allegro and its subsidiaries taken as a whole; provided, however, that the
continuation of current trends in such business, assets (including intangible
assets), financial condition or results of operations (including without
limitation further losses) shall not be deemed to constitute a Material Adverse
Effect, but material deviations therefrom shall constitute a Material Adverse
Effect.
 
     3.2 Allegro Capital Structure.  The authorized capital stock of Allegro
consists of 18,000,000 shares of Common Stock, par value $.001 per share, of
which there were 4,444,477 shares issued and outstanding as of October 1, 1996,
2,000,000 shares of Class A Preferred Stock, par value $.001 per share, of which
there were no shares issued and outstanding as of October 1, 1996, 60,520 shares
of Class B Voting Preferred Stock, par value $.001 per share, of which there
were 60,520 shares issued and outstanding as of October 1, 1996 and 1,939,480
shares of Serial Preferred Stock, par value $.001 per share, of which no shares
were issued or outstanding as of October 1, 1996. The authorized capital stock
of Merger Sub consists of 1,000 shares of Common Stock, par value $.001 per
share, 100 shares of which, as of the date hereof, are issued and outstanding
and are held by Allegro. All outstanding shares of the Common Stock of Allegro
are duly authorized, validly issued, fully paid and non-assessable and are not
subject to preemptive rights created by statute, the Certificate of
Incorporation or Bylaws of Allegro or any agreement or document to which Allegro
is a party or by which it is bound. As of October 1, 1996, Allegro had reserved
an aggregate of 1,500,000 shares of Common Stock, net of exercises, for issuance
to employees, consultants and non-employee directors pursuant to Allegro's 1994
Long-Term Incentive Plan and Allegro's Outside Directors and Advisors Stock
Option Plan (collectively, the "Allegro Stock Option Plans"), under which
options are outstanding for an aggregate 1,106,115 shares. All shares of the
Common Stock of Allegro subject to issuance as aforesaid, upon issuance on the
terms and conditions specified in the instruments pursuant to which they are
issuable, would be duly authorized, validly issued, fully paid and
nonassessable. The Allegro Schedules list each outstanding option to acquire
shares of the Common Stock Allegro at June 30, 1996, the name of the holder of
such
 
                                      A-12
<PAGE>   205
 
option, the number of shares subject to such option, the exercise price of such
option, the number of shares as to which such option will have vested at such
date and whether the exercisability of such option will be accelerated in any
way by the transactions contemplated by this Agreement or for any other reason,
and indicate the extent of acceleration, if any.
 
     3.3 Obligations With Respect to Capital Stock.  Except as set forth in
Section 3.2, there are no equity securities of any class of Allegro, or any
securities exchangeable or convertible into or exercisable for such equity
securities, issued, reserved for issuance or outstanding. Except for securities
Allegro owns, directly or indirectly through one or more subsidiaries, there are
no equity securities of any class of any subsidiary of Allegro, or any security
exchangeable or convertible into or exercisable for such equity securities,
issued, reserved for issuance or outstanding. Except as set forth in Section
3.2, there are no options, warrants, equity securities, calls, rights (including
preemptive rights), commitments or agreements of any character to which Allegro
or any of its subsidiaries is a party or by which it is bound obligating Allegro
or any of its subsidiaries to issue, deliver or sell, or cause to be issued,
delivered or sold, or repurchase, redeem or otherwise acquire, or cause the
repurchase, redemption or acquisition, of any shares of capital stock of Allegro
or any of its subsidiaries or obligating Allegro or any of its subsidiaries to
grant, extend, accelerate the vesting of or enter into any such option, warrant,
equity security, call, right, commitment or agreement. There are no registration
rights and, to the knowledge of Allegro there are no voting trusts, proxies or
other agreements or understandings with respect to any equity security of any
class of Allegro or with respect to any equity security of any class of any of
its subsidiaries.

authority to enter into this Agreement and to consummate the transactions

Agreement has been duly executed and delivered by each of Allegro and Merger Sub
and, assuming the due authorization, execution and delivery of this Agreement by
SPC, this Agreement constitutes the valid and binding obligations of each of
Allegro and Merger Sub, enforceable in accordance with its terms, except as
enforceability may be limited by bankruptcy and other similar laws and general
principles of equity. The execution and delivery of this Agreement by each of
Allegro and Merger Sub do not, and the performance of this Agreement by each of

Incorporation or Bylaws of Allegro or the Certificate of Incorporation or Bylaws
of Merger Sub or the equivalent organizational documents of any of its other
subsidiaries, (ii) subject to obtaining the approval of the Merger by Allegro's
stockholders as contemplated in Section 5.2 and compliance with the requirements

subsidiaries (including Merger Sub) or by which its or any of their respective
properties is bound or affected, or (iii) result in any breach of or constitute
a default (or an event that with notice or lapse of time or both would become a
default) under, or impair Allegro's rights or alter the rights or obligations of
any third party under, or give to others any rights of termination, amendment,
acceleration or cancellation of, or result in the creation of a lien or
encumbrance on any of the properties or assets of Allegro or any of its
subsidiaries (including Merger Sub) pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which Allegro or any of its subsidiaries (including
Merger Sub) is a party or by which Allegro or any of its sub sidiaries
(including Merger Sub) or its or any of their respective properties are bound or
affected, except, with respect to clauses (ii) and (iii), for any such
conflicts, violations, defaults or other occurrences that would not have a
Material Adverse Effect on Allegro. The Allegro Schedules list all material
consents, waivers and approvals under any of Allegro's or any of its
subsidiaries' agreements, contracts, licenses or leases required to be obtained
in connection with the consummation of the transactions contemplated hereby.
 
     (b) No consent, approval, order or authorization of, or registration,
declaration or filing with any Governmental Entity is required by or with
respect to Allegro or Merger Sub in connection with the execution
 
                                      A-13
<PAGE>   206

authorizations, filings, approvals and registrations which, if not obtained or
made, would not have a Material Adverse Effect on SPC or Allegro or have a
material adverse effect on the ability of the parties to consummate the Merger.
 
     3.5 Section 203 of the Delaware General Corporation Law Not
Applicable.  The Board of Directors of Allegro has taken all actions so that the
restrictions contained in Section 203 of the Delaware General Corporation Law
applicable to a "business combination" (as defined in Section 203) will not
apply to the execution, delivery or performance of this Agreement or to the
consummation of the Merger or the other transactions contemplated by this
Agreement.
 
     3.6 SEC Filings; Allegro Financial Statements.
 
     (a) Allegro has filed all forms, reports and documents required to be filed
with the SEC since and including December 1995, and has made available to SPC
such forms, reports and documents in the form filed with the SEC. All such
required forms, reports and documents (including those that Allegro may file
subsequent to the date hereof) are referred to herein as the "Allegro SEC
Reports." As of their respective dates, the Allegro SEC Reports (i) were
prepared in accordance with the requirements of the Securities Act or the
Exchange Act, as the case may be, and the rules and regulations of the SEC
thereunder applicable to such Allegro SEC Reports, and (ii) did not at the time
they were filed (or if amended or superseded by a filing prior to the date of
this Agreement, then on the date of such filing) contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. None of Allegro's
subsidiaries is required to file any forms, reports or other documents with the
SEC.
 
     (b) Each of the consolidated financial statements (including, in each case,
any related notes thereto) contained in Allegro SEC Reports (the "Allegro
Financials"), including any Allegro SEC Reports filed after the date hereof
until the Closing, (x) complied as to form in all material respects with the
published rules and regulations of the SEC with respect thereto, (y) was
prepared in accordance with generally accepted accounting principles ("GAAP")
applied on a consistent basis throughout the periods involved (except as may be
indicated in the notes thereto or, in the case of unaudited interim financial
statements, as may be permitted by the SEC on Form 10-QSB under the Exchange
Act) and (z) fairly presented the consolidated financial position of Allegro and
its subsidiaries as at the respective dates thereof and the consolidated results
of its operations and cash flows for the periods indicated, except that the
unaudited interim financial statements were or are subject to normal and
recurring year-end adjustments which were not, or are not expected to be,
material in amount. The balance sheet of Allegro contained in Allegro SEC
Reports as of June 30, 1996 is hereinafter referred to as the "Allegro Balance
Sheet." Except as disclosed in the Allegro Financials, neither Allegro nor any
of its subsidiaries has any liabilities (absolute, accrued, contingent or
otherwise) of a nature required to be disclosed on a balance sheet or in the
related notes to the consolidated financial statements prepared in accordance
with GAAP which are, individually or in the aggregate, material to the business,
results of operations or financial condition of Allegro and its subsidiaries
taken as a whole, except liabilities (i) provided for in the Allegro Balance
Sheet, or (ii) incurred since the date of the Allegro Balance Sheet in the
ordinary course of business consistent with past practices.
 
     (c) Allegro has heretofore furnished to SPC a complete and correct copy of
any amendments or modifications, which have not yet been filed with the SEC but
which are required to be filed, to agreements, documents or other instruments
which previously had been filed by Allegro with the SEC pursuant to the
Securities Act or the Exchange Act.
 
                                      A-14
<PAGE>   207
 
     3.7 Absence of Certain Changes or Events.  Since the date of the Allegro
Balance Sheet through the date of this Agreement, there has not been: (i) any
Material Adverse Effect on Allegro, (ii) any material change by Allegro in its
accounting methods, principles or practices, except as required by concurrent
changes in GAAP, or (iii) any revaluation by Allegro of any of its assets having
a Material Adverse Effect on Allegro, including, without limitation, writing
down the value of capitalized software or inventory or writing off notes or
accounts receivable other than in the ordinary course of business.
 
     3.8 Taxes.  Allegro and each of its subsidiaries has filed all tax returns
required to be filed by any of them and has paid (or Allegro has paid on its
behalf), or has set up an adequate reserve for the payment of, all material
taxes required to be paid as shown on such returns and the most recent financial
statements contained in the Allegro SEC Reports reflect an adequate reserve for
all material taxes payable by Allegro and its subsidiaries accrued through the
date of such financial statements. Except as reasonably would not be expected to
have a Material Adverse Effect on Allegro, no deficiencies for any taxes have
been proposed, asserted or assessed against Allegro or any of its subsidiaries.
 
     3.9 Intellectual Property.
 
     (a) To the knowledge of Allegro and its subsidiaries, Allegro and its
subsidiaries own, or have the right to use, sell or license all patents,
trademarks, trade names, service marks, copyrights and other intellectual
property necessary or required for the conduct of their respective businesses as
presently conducted (such intellectual property and the rights thereto are
collectively referred to herein as the "Allegro IP Rights"), except for any
failure to own or have the right to use, sell or license that would not have a
Material Adverse Effect on Allegro.
 
     (b) The execution, delivery and performance of this Agreement and the
consummation of the transactions contemplated hereby will not constitute a
breach of any instrument or agreement governing any Allegro IP Rights (the
"Allegro IP Rights Agreements"), will not cause the forfeiture or termination or
give rise to a right of forfeiture or termination of any Allegro IP Rights or
impair the right of Allegro and its subsidiaries to use, sell or license any
Allegro IP Rights or portion thereof, except for the occurrence of any such
breach, forfeiture, termination or impairment that would not individually or in
the aggregate, result in a Material Adverse Effect on Allegro.
 
     (c) To the knowledge of Allegro and its subsidiaries, (i) neither the
manufacture, marketing, license, sale or intended use of any product or
technology currently licensed or sold or under development by Allegro or any of
its subsidiaries violates any license or agreement between Allegro or any of its
subsidiaries and any third party or infringes any intellectual property right of
any other party; and (ii) there is no pending or, to the knowledge of Allegro,
threatened claim, arbitration or litigation contesting the validity, ownership
or right to use, sell, license or dispose of any Allegro IP Rights, nor has
Allegro received any written notice asserting that any Allegro IP Rights or the
proposed use, sale, license or disposition thereof conflicts or will conflict
with the rights of any other party, except, with respect to clauses (i) and
(ii), for any violations, infringements, claims or litigation that would not
have a Material Adverse Effect on Allegro.
 
     (d) Allegro has taken reasonable and practicable steps designed to
safeguard and maintain the secrecy and confidentiality of, and its proprietary
rights in, all Allegro IP Rights.
 
     3.10 Compliance; Permits; Restrictions.
 
     (a) Neither Allegro nor any of its subsidiaries is in conflict with, or in
default or violation of, (i) any law, rule, regulation, order, judgment or
decree applicable to Allegro or any of its subsidiaries or by which its or any
of their respective properties is bound or affected, or (ii) any note, bond,
mortgage, indenture, contract, agreement, lease, license, permit, franchise or
other instrument or obligation to which Allegro or any of its subsidiaries is a
party or by which Allegro or any of its subsidiaries or its or any of their
respective properties is bound or affected, except for any conflicts, defaults
or violations which would not have a Material Adverse Effect on Allegro. No
investigation or review by any governmental or, to the knowledge of Allegro,
regulatory body or authority is pending or threatened against Allegro or its
subsidiaries, nor has any governmental or regulatory body or authority indicated
an intention to conduct the same, other than, in each such case, those the
outcome of which would not have a Material Adverse Effect on Allegro.
 
                                      A-15
<PAGE>   208
 
     (b) Allegro and its subsidiaries hold all permits, licenses, variances,
exemptions, orders and approvals from governmental authorities which are
material to the operation of the business of Allegro and its subsidiaries taken
as a whole (collectively, the "Allegro Permits"). Allegro and its subsidiaries
are in compliance with the terms of Allegro Permits, except where the failure to
hold the same or to so comply would not have a Material Adverse Effect on
Allegro.
 
     3.11 Litigation.  There is no action, suit, proceeding, claim, arbitration
or investigation pending, or as to which Allegro or any of its subsidiaries has
received any notice of assertion nor, to Allegro's knowledge, is there a written
threat of an action, suit, proceeding, claim, arbitration or investigation
against Allegro or any of its subsidiaries which would have a Material Adverse
Effect on Allegro, or which in any manner challenges or seeks to prevent,
enjoin, alter or delay any of the transactions contemplated by this Agreement.
 
     3.12 Brokers' and Finders' Fees.  Except for fees payable to Frost Capital
Partners, Inc. and Joseph Abrams disclosed to SPC, Allegro has not incurred, nor
will it incur, directly or indirectly, any liability for brokerage or finders'
fees or agents' commissions or any similar charges in connection with this
Agreement or any transaction contemplated hereby.
 
     3.13 Employee Benefit Plans.
 
     (a) With respect to each material employee benefit plan, program,
arrangement and contract (including, without limitation, any "employee benefit
plan" as defined in Section 3(3) of ERISA) maintained or contributed to by
Allegro or any ERISA Affiliate thereof which is under common control with
Allegro within the meaning of Section 414 of the Code (the "Allegro Employee
Plans"), Allegro has made available to SPC a true and complete copy of, to the
extent applicable, (i) such Allegro Employee Plan, (ii) the most recent annual
report (Form 5500), (iii) each trust agreement related to such Allegro Employee
Plan, (iv) the most recent summary plan description for each Allegro Employee
Plan for which such a description is required, (v) the most recent actuarial
report relating to any Allegro Employee Plan subject to Title IV of ERISA and
(vi) the most recent IRS determination letter issued with respect to any Allegro
Employee Plan.
 
     (b) Each Allegro Employee Plan which is intended to be qualified under
Section 401(a) of the Code has received a favorable determination from the IRS
covering the provisions of the Tax Reform Act of 1986 stating that such Allegro
Employee Plan is so qualified and nothing has occurred since the date of such
letter that could reasonably be expected to affect the qualified status of such
plan. Each Allegro Employee Plan has been operated in all material respects in
accordance with its terms and the requirements of applicable law. Neither
Allegro nor any ERISA Affiliate of Allegro has incurred or is reasonably
expected to incur any material liability under Title IV of ERISA in connection
with any Allegro Employee Plan.
 
     (c) Neither Allegro nor any ERISA Affiliate thereof has withdrawn in a
complete or partial withdrawal from any multi-employer plan within the meaning
of Section 4001(a)(3) of ERISA prior to the Effective Time. Neither Allegro nor
any ERISA Affiliate thereof has contributed to or been obligated to contribute
to any multi-employer plan within the meaning of Section 4001(a)(3) of ERISA.

subsidiaries has good and valid title to, or, in the case of leased properties
and assets, valid leasehold interests in, all of its material tangible
properties and assets, real, personal and mixed, used in its business, free and
clear of any liens or encumbrances except as reflected in the Allegro Financials
and except for liens for taxes not yet due and payable and such imperfections of
title and encumbrances, if any, which would not have a Material Adverse Effect
on Allegro.
 
     3.15 Environmental Matters.
 
     (a) Hazardous Material.  Except as would not have a Material Adverse Effect
on Allegro, no underground storage tanks and no Hazardous Materials (but
excluding office and janitorial supplies) are present in the soil, ground water,
building materials or ambient air of any real property currently occupied by
SPC, as a result of the deliberate actions of Allegro or any of its
subsidiaries, and Allegro has not received any notice that it is allegedly
liable for the presence of Hazardous Materials in, on or under any other
property,
 
                                      A-16
<PAGE>   209
 
including the land and the improvements, ground water and surface water thereof,
that Allegro has at any time owned, operated, occupied or leased.
 
     (b) Hazardous Materials Activities.  Except as would not have a Material
Adverse Effect on Allegro, neither Allegro nor any of its subsidiaries has
transported, stored, used, manufactured, disposed of, released or exposed its
employees or others to Hazardous Materials in violation of any law in effect on
or before the Closing Date, nor has Allegro or any of its subsidiaries engaged
in any Hazardous Materials Activities in violation of any rule, regulation,
treaty or statute promulgated by any Governmental Entity in effect prior to or
as of the date hereof to prohibit, regulate or control Hazardous Materials or
any Hazardous Material Activity.
 
     (c) Permits.  Allegro and its subsidiaries currently hold all environmental
approvals, permits, licenses, clearances and consents (the "Allegro
Environmental Permits") necessary for the conduct of Allegro's and its
subsidiaries' Hazardous Material Activities as currently conducted and other
businesses of Allegro and its subsidiaries as such activities and businesses are
currently being conducted, except where the failure to so hold would not have a
Material Adverse Effect on Allegro.
 
     (d) Environmental Liabilities.  No material action, proceeding, revocation
proceeding, amendment procedure, writ, injunction or claim is pending, or to
Allegro's knowledge, threatened concerning any Allegro Environmental Permit or
any Hazardous Materials Activity of Allegro or any of its subsidiaries. Allegro
is not aware of any fact or circumstance which could involve Allegro or any of
its subsidiaries in any environmental litigation or impose upon Allegro or any
of its subsidiaries any environmental liability that would have a Material
Adverse Effect on Allegro.
 
     3.16 Labor Matters.  To Allegro's knowledge, there are no activities or
proceedings of any labor union to organize any employees of Allegro or any of
its subsidiaries and there are no strikes, or material slowdowns, work stoppages
or lockouts, or threats thereof by or with respect to any employees of Allegro
or any of its subsidiaries. Allegro and its subsidiaries are and have been in
compliance with all applicable laws regarding employment practices, terms and
conditions of employment, and wages and hours (including, without limitation,
ERISA, WARN or any similar state or local law), except for any noncompliance
that would not have a Material Adverse Effect on Allegro.

under, any of the material terms or conditions of any of the agreements,
contracts or commitments to which Allegro is a party or by which it is bound of
the type described in clauses (a) through (l) above (any such agreement,
contract or commitment, an "Allegro Contract") in such a manner as would permit
any other party to cancel or terminate any such Allegro Contract, or would
permit any other party to seek damages, which would have a Material Adverse
Effect on Allegro.
 
     3.18 Change of Control Payments.  There are no plans or agreements pursuant
to which any material amounts may become payable (whether currently or in the
future) to current or former officers or directors of Allegro as a result of or

untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein not
misleading. The information supplied by Allegro for inclusion in the Proxy
Statement to be sent to the stockholders of Allegro and the stockholders of SPC
in connection with the Allegro Stockholders' Meeting and SPC Stockholders'
Meeting shall not, on the date the Proxy Statement is first mailed to Allegro's
stockholders and SPC's stockholders, at the time of the SPC Stockholders'
Meeting or the Allegro Stockholders' Meeting and at the Effective Time, contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not false or
misleading; or omit to state any material fact necessary to correct any
statement in any earlier communication with respect to the solicitation of
proxies for the Allegro Stockholders' Meeting or the SPC Stockholders' Meeting
which has become false or misleading. The Proxy Statement will comply as to form
in all material respects with the provisions of the Exchange Act and the rules
and regulations thereunder. If at any time prior to the Effective Time, any
event relating to Allegro or any of its affiliates, officers or directors should
be discovered by Allegro which should be set forth in an amendment to the
Registration Statement or a supplement to the Proxy Statement, Allegro shall
promptly inform SPC. Notwithstanding the foregoing, Allegro makes no
representation or warranty with respect to any information supplied by SPC which
is contained in any of the foregoing documents.

of this Agreement, determined (i) that the Merger is fair to and in the best
interests of Allegro and its stockholders, and (ii) to recommend that the

or taxes, to pay or perform other material obligations when due, and use its
commercially reasonable efforts consistent with past practices and policies to
preserve intact its present business organization, keep available the services
of its present officers and employees and preserve its relationships with
customers, suppliers, distributors, licensors, licensees, and others with which
it has business dealings. In furtherance of the foregoing and subject to
applicable law, SPC and Allegro agree to confer, as promptly as practicable,
prior to taking any material actions or making any material management decisions

                             ADDITIONAL AGREEMENTS
 
     5.1 Proxy Statement/Prospectus; Registration Statement; Other Filings.  As
promptly as practicable after the execution of this Agreement, SPC and Allegro
will prepare and file with the SEC the Proxy Statement and Allegro will prepare
and file with the SEC the Registration Statement in which the Proxy Statement
will be included as a prospectus. Each of SPC and Allegro will respond to any
comments of the SEC, will use its best efforts to have the Registration
Statement declared effective under the Securities Act as promptly as practicable
after such filing and will cause the Proxy Statement to be mailed to its
stockholders at the earliest practicable time. As promptly as practicable after
the date of this Agreement, SPC and Allegro will prepare and file any other
filings required under the Exchange Act, the Securities Act or any other
Federal, foreign or state securities or Blue Sky laws relating to the Merger and
the transactions contemplated by this Agreement (the "Other Filings"). Each
party will notify the other party promptly upon the receipt of any comments from
the SEC or its staff and of any request by the SEC or its staff or any other
government officials for amendments or supplements to the Registration
Statement, the Proxy Statement or any Other
 
                                      A-20
<PAGE>   213
 
Filing or for additional information and will supply the other party with copies
of all correspondence between such party or any of its representatives, on the
one hand, and the SEC, or its staff or any other government officials, on the
other hand, with respect to the Registration Statement, the Proxy Statement, the
Merger or any Other Filing. The Proxy Statement, the Registration Statement and
the Other Filings will comply in all material respects with all applicable
requirements of law and the rules and regulations promulgated thereunder.
Whenever any event occurs which is required to be set forth in an amendment or
supplement to the Proxy Statement, the Registration Statement or any Other
Filing, SPC or Allegro, as the case may be, will promptly inform the other party
of such occurrence and cooperate in filing with the SEC or its staff or any
other government officials, and/or mailing to stockholders of SPC and Allegro,
such amendment or supplement. The Proxy Statement will also include the
recommendations of (i) the Board of Directors of SPC in favor of approval of
this Agreement (except to the extent permitted by Section 5.4) and (ii) the
Board of Directors of Allegro in favor of the approval of this Agreement (except
that the Board of Directors of Allegro may withdraw, modify or refrain from
making such recommendations to the extent that the Board determines, in good
faith, after discussion with outside legal counsel, that the Board's fiduciary
duties under applicable law require it to do so).
 
     5.2 Meetings of Stockholders.  Promptly after the date hereof, SPC will
take all action necessary in accordance with Delaware Law and its Certificate of
Incorporation and Bylaws to convene the SPC Stockholders' Meeting to be held as
promptly as practicable, and in any event within 45 days after the declaration
of effectiveness of the Registration Statement, for the purpose of voting upon
this Agreement. SPC will consult with Allegro and use its commercially
reasonable efforts to hold the SPC Stockholders' Meeting on the same day as the
Allegro Stockholders' Meeting. Promptly after the date hereof, Allegro will take
all action necessary in accordance with the Delaware General Corporation Law and
its Certificate of Incorporation and Bylaws to convene the Allegro Stockholders'
Meeting to be held as promptly as practicable, and in any event within 45 days
after the declaration of effectiveness of the Registration Statement, for the
purpose of voting upon this Agreement. Allegro will consult with SPC and will
use its commercially reasonable efforts to hold the Allegro Stockholders'
Meeting on the same day as the SPC Stockholders' Meeting. Allegro and SPC will
each use its commercially reasonable efforts to solicit from its stockholders
proxies in favor of the approval of this Agreement and will take all other
action necessary or advisable to secure the vote or consent of their respective
stockholders required by the Delaware General Corporation Law to obtain such
approval (except to the extent permitted by Section 5.4).
 
     5.3 Access to Information; Confidentiality.
 
     (a) Each party will afford the other party and its accountants, counsel and
other representatives reasonable access during normal business hours to the
properties, books, records and personnel of the other party during the period
prior to the Effective Time to obtain all information concerning the business,
including the status of product development efforts, properties, results of
operations and personnel of such party, as the other party may reasonably
request. No information or knowledge obtained in any investigation pursuant to
this Section 5.3 will affect or be deemed to modify any representation or
warranty contained herein or the conditions to the obligations of the parties to
consummate the Merger.
 
     (b) The parties acknowledge that Allegro and SPC have previously executed a
Confidentiality Agreement (the "Confidentiality Agreement"), which
Confidentiality Agreement will continue in full force and effect in accordance
with its terms, except as is necessary to comply with the terms of this
Agreement.
 
     5.4 No Solicitation by SPC.
 
     (a) From and after the date of this Agreement until the earlier of the
Effective Time or termination of this Agreement pursuant to its terms, SPC and
its subsidiaries will not, and will instruct their respective directors,
officers, employees, representatives, investment bankers, agents and affiliates
not to, directly or indirectly, (i) solicit or knowingly encourage submission
of, any proposals or offers by any person, entity or group (other than Allegro
and its affiliates, agents and representatives), or (ii) participate in any
discussions or negotiations with, or disclose any non-public information
concerning SPC or any of its subsidiaries to, or afford any access to the
properties, books or records of SPC or any of its subsidiaries to, or otherwise
assist or facilitate, or enter into any agreement or understanding with, any
person, entity or group (other than Allegro
 
                                      A-21
<PAGE>   214
 
and its affiliates, agents and representatives), in connection with any
Acquisition Proposal with respect to SPC. For the purposes of this Agreement, an
"Acquisition Proposal" with respect to an entity means any proposal or offer
relating to (i) any merger, consolidation, sale of substantial assets or similar
transactions involving the entity or any subsidiaries of the entity (other than
sales of assets or inventory in the ordinary course of business or permitted
under the terms of this Agreement), (ii) sale of 5% or more of the outstanding
shares of capital stock of the entity (including without limitation by way of a
tender offer or an exchange offer), (iii) the acquisition by any person of
beneficial ownership or a right to acquire beneficial ownership of, or the
formation of any "group" (as defined under Section 13(d) of the Exchange Act and
the rules and regulations thereunder) which beneficially owns, or has the right
to acquire beneficial ownership of, 5% or more of the then outstanding shares of
capital stock of the entity (except for acquisitions for passive investment
purposes only in circumstances where the person or group qualifies for and files
a Schedule 13G with respect thereto); or (iv) any public announcement of a
proposal, plan or intention to do any of the foregoing or any agreement to
engage in any of the foregoing. SPC will immediately cease any and all existing
activities, discussions or negotiations with any parties conducted heretofore
with respect to any of the foregoing. SPC will (i) notify Allegro as promptly as
practicable if any inquiry or proposal is made or any information or access is
requested in writing in connection with an Acquisition Proposal or potential
Acquisition Proposal and (ii) as promptly as practicable notify Allegro of the
significant terms and conditions of any such Acquisition Proposal. In addition,
subject to the other provisions of this Section 5.4, from and after the date of
this Agreement until the earlier of the Effective Time and termination of this
Agreement pursuant to its terms, SPC and its subsidiaries will not, and will
instruct their respective directors, officers, employees, representatives,
investment bankers, agents and affiliates not to, directly or indirectly, make
or authorize any public statement, recommendation or solicitation in support of
any Acquisition Proposal made by any person, entity or group (other than
Allegro); provided, however, that nothing herein shall prohibit SPC's Board of
Directors from taking and disclosing to SPC's stockholders a position with
respect to a tender offer pursuant to Rules 14d-9 and 14e-2 promulgated under
the Exchange Act.
 
     (b) Notwithstanding the provisions of paragraph (a) above, prior to the
approval of this Agreement by the stockholders of SPC at the SPC Stockholders'
Meeting, SPC may, to the extent the Board of Directors of SPC determines, in
good faith, after consultation with outside legal counsel, that the Board's
fiduciary duties under applicable law require it to do so, participate in
discussions or negotiations with, and, subject to the requirements of paragraph
(c), below, furnish information to any person, entity or group after such
person, entity or group has delivered to SPC in writing, an unsolicited bona
fide Acquisition Proposal which the Board of Directors of SPC in its good faith
reasonable judgment determines, after consultation with its independent
financial advisors, would result in a transaction more favorable to the
stockholders of SPC from a financial point of view than the Merger and for which
financing, to the extent required, is then committed or which, in the good faith
reasonable judgment of the Board of Directors of SPC (based upon the advice of
independent financial advisors), is reasonably capable of being financed by such
person, entity or group and which is likely to be consummated (an "SPC Superior
Proposal"). In addition, notwithstanding the provisions of paragraph (a) above,
in connection with a possible Acquisition Proposal, SPC may refer any third
party to this Section 5.4 or make a copy of this Section 5.4 available to a
third party. In the event SPC receives an SPC Superior Proposal, nothing
contained in this Agreement (but subject to the terms hereof) will prevent the
Board of Directors of SPC from approving such SPC Superior Proposal or
recommending such SPC Superior Proposal to SPC's stockholders, if the Board
determines that such action is required by its fiduciary duties under applicable
law; in such case, the Board of Directors of SPC may withdraw, modify or refrain
from making its recommendation concerning the approval of this Agreement;
provided, however, that SPC shall not accept or recommend to its stockholders,
or enter into any agreement concerning, an SPC Superior Proposal for a period of
not less than 48 hours after Allegro's receipt of a copy of such SPC Superior
Proposal (or a description of the significant terms and conditions thereof, if
not in writing).
 
     (c) Notwithstanding anything to the contrary in paragraph (a), SPC will not
provide any non-public information to a third party unless: (x) SPC provides
such non-public information pursuant to a nondisclosure agreement with terms
regarding the protection of confidential information at least as restrictive as
such terms in the Confidentiality Agreement; and (y) such non-public information
is the same information previously delivered to Allegro.
 
                                      A-22
<PAGE>   215
 
     5.5 Public Disclosure.  Allegro and SPC will consult with each other before
issuing any press release or otherwise making any public statement with respect
to the Merger, this Agreement or an Alternative Proposal and will not issue any
such press release or make any such public statement prior to such consultation,
except as may be required by law or any listing agreement with a national
securities exchange or Nasdaq.
 
     5.6 Legal Requirements.  Each of Allegro, Merger Sub and SPC will take all
reasonable actions necessary or desirable to comply promptly with all legal
requirements which may be imposed on them with respect to the consummation of
the transactions contemplated by this Agreement (including furnishing all
information required in connection with approvals of or filings with any
Governmental Entity, and prompt resolution of any litigation prompted hereby)
and will promptly cooperate with and furnish information to any party hereto
necessary in connection with any such requirements imposed upon any of them or
their respective subsidiaries in connection with the consummation of the
transactions contemplated by this Agreement. Allegro will use its commercially
reasonable efforts to take such steps as may be necessary to comply with the
securities and blue sky laws of all jurisdictions which are applicable to the
issuance of Allegro Common Stock pursuant hereto. SPC will use its commercially
reasonable efforts to assist Allegro as may be necessary to comply with the
securities and blue sky laws of all jurisdictions which are applicable in
connection with the issuance of Allegro Common Stock pursuant hereto.
 
     5.7 Third Party Consents.  As soon as practicable following the date
hereof, Allegro and SPC will each use its commercially reasonable efforts to
obtain all material consents, waivers and approvals under any of its or its
subsidiaries' agreements, contracts, licenses or leases required to be obtained
in connection with the consummation of the transactions contemplated hereby.
 
     5.8 FIRPTA.  At or prior to the Closing, SPC, if requested by Allegro,
shall deliver to the IRS a notice that the SPC Capital Stock is not a "U.S. Real
Property Interest" as defined and in accordance with the requirements of
Treasury Regulation Section 1.897-2(h)(2).
 
     5.9 Notification of Certain Matters.  Allegro and Merger Sub will give
prompt notice to SPC, and SPC will give prompt notice to Allegro, of the
occurrence, or failure to occur, of any event, which occurrence or failure to
occur would be reasonably likely to cause (a) any representation or warranty
contained in this Agreement to be untrue or inaccurate in any material respect
at any time from the date of this Agreement to the Effective Time, or (b) any
material failure of Allegro and Merger Sub or SPC, as the case may be, or of any
officer, director, employee or agent thereof, to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it under
this Agreement. Notwithstanding the above, the delivery of any notice pursuant
to this section will not limit or otherwise affect the remedies available
hereunder to the party receiving such notice.
 
     5.10 Best Efforts and Further Assurances.  Subject to the respective rights
and obligations of Allegro and SPC under this Agreement, each of the parties to
this Agreement will use its best efforts to effectuate the Merger and the other
transactions contemplated hereby and to fulfill and cause to be fulfilled the
conditions to closing under this Agreement. Each party hereto, at the reasonable
request of another party hereto, will execute and deliver such other instruments
and do and perform such other acts and things as may be necessary or desirable
for effecting completely the consummation of the transactions contemplated
hereby.
 
     5.11 Stock Options; Employee Stock Purchase Plan.
 
     (a) At the Effective Time, each outstanding option to purchase shares of
SPC Capital Stock (each an "SPC Stock Option") under the SPC Stock Option Plans,
whether or not exercisable, will be assumed by Allegro. Each SPC Stock Option so
assumed by Allegro under this Agreement will continue to have, and be subject
to, the same terms and conditions set forth in the applicable SPC Stock Option
Plan immediately prior to the Effective Time (including, without limitation, any
repurchase rights), except that (i) each SPC Stock Option will be exercisable
(or will become exercisable in accordance with its terms) for that number of
whole shares of Allegro Common Stock equal to the product of the number of
shares of SPC Capital Stock that were issuable upon exercise of such SPC Stock
Option immediately prior to the Effective Time multiplied by the Exchange Ratio,
rounded down to the nearest whole number of shares of Allegro Common Stock, and
(ii) the per share exercise price for the shares of Allegro Common Stock
issuable upon exercise of such assumed SPC
 
                                      A-23
<PAGE>   216
 
Stock Option will be equal to the quotient determined by dividing the exercise
price per share of SPC Capital Stock at which such SPC Stock Option was
exercisable immediately prior to the Effective Time by the Exchange Ratio,
rounded up to the nearest whole cent. After the Effective Time, Allegro will
issue to each holder of an outstanding SPC Stock Option a notice describing the
foregoing assumption of such SPC Stock Option by Allegro.
 
     (b) It is the intention of the parties that SPC Stock Options assumed by
Allegro qualify following the Effective Time as incentive stock options as
defined in Section 422 of the Code to the extent SPC Stock Options qualified as
incentive stock options immediately prior to the Effective Time.
 
     (c) Allegro will reserve sufficient shares of Allegro Common Stock for
issuance under Section 5.11(a) and under Section 1.6(c) hereof.
 
     5.12 Form S-8.  Allegro agrees to file a registration statement on Form S-8
for the shares of Allegro Common Stock issuable with respect to assumed SPC
Stock Options no later than ten (10) business days after the Closing Date.
 
     5.13 Indemnification and Insurance.
 
     (a) From and after the Effective Time, the Surviving Corporation will
fulfill and honor in all respects the obligations of SPC pursuant to any
indemnification agreements between SPC and its directors and officers existing
prior to the date hereof. The Certificate of Incorporation and Bylaws of the
Surviving Corporation will contain provisions with respect to indemnification
and elimination of liability for monetary damages not less favorable to officers
and directors to those set forth in the Certificate of Incorporation and Bylaws
of SPC, which provisions will not be amended, repealed or otherwise modified in
a manner adverse to officers and directors for a period of six years from the
Effective Time in any manner that would adversely affect the rights thereunder
of individuals who, at the Effective Time, were directors, officers, employees
or agents of SPC, unless such modification is required by law.
 
     (b) After the Effective Time the Surviving Corporation will, to the fullest
extent permitted under applicable law or under the Surviving Corporation's
Certificate of Incorporation or Bylaws, indemnify and hold harmless, each
present and former director or officer of SPC or any of its subsidiaries
(collectively, the "Indemnified Parties") against any costs or expenses
(including attorneys' fees), judgments, fines, losses, claims, damages,
liabilities and amounts paid in settlement in connection with any claim, action,
suit, proceeding or investigation, whether civil, criminal, administrative or
investigative, to the extent arising out of or pertaining to any action or
omission in his or her capacity as a director or officer of SPC arising out of
or pertaining to the transactions contemplated by this Agreement for a period of
six years after the date hereof. In the event of any such claim, action, suit,
proceeding or investigation (whether arising before or after the Effective
Time), (i) any counsel retained by the Indemnified Parties for any period after
the Effective Time will be reasonably satisfactory to the Surviving Corporation
and Allegro, (ii) after the Effective Time, the Surviving Corporation will pay
the reasonable fees and expenses of such counsel, promptly after statements
therefor are received and (iii) the Surviving Corporation will cooperate in the
defense of any such matter; provided, however, that the Surviving Corporation
will not be liable for any settlement effected without its written consent
(which consent will not be unreasonably withheld); and provided, further, that,
in the event that any claim or claims for indemnification are asserted or made
within such six-year period, all rights to indemnification in respect of any
such claim or claims will continue until the disposition of any and all such
claims. The Indemnified Parties as a group may retain only one law firm (in
addition to local counsel) to represent them with respect to any single action
unless there is, under applicable standards of professional conduct, a conflict
on any significant issue between the positions of any two or more Indemnified
Parties.
 
     (c) Allegro shall maintain through September 3, 1997 the current policies
of directors' and officers' liability insurance maintained by SPC. The Surviving
Corporation shall pay all retentions and deductibles payable by any Indemnified
Party with respect to such policies; provided, that if and to the extent the
Surviving Corporation has insufficient cash to pay such retentions and
deductibles in full, the remaining amounts payable shall be paid by Allegro.
 
                                      A-24
<PAGE>   217
 
     (d) Promptly after the Effective Time, Allegro shall enter into
indemnification agreements with directors and officers of SPC who become
directors or officers of Allegro or of the Surviving Corporation, which
agreements shall be substantially identical to those which Allegro has entered
with its current officers and directors.
 
     (e) This Section 5.13 will survive any termination of this Agreement and
the consummation of the Merger at the Effective Time, is intended to benefit
SPC, the Surviving Corporation and the Indemnified Parties, and will be binding
on all successors and assigns of the Surviving Corporation. If Allegro or the
Surviving Corporation or any of their respective successors or assigns (i)
consolidates with or merges into any other person or entity and shall not be the
continuing or surviving person of such consolidation or merger or (ii) transfers
all or substantially all of its properties and assets to any person or entity,
then and in each such case, proper provision shall be made so that such
successors or assigns of Allegro or the Surviving Corporation, as the case may
be, shall assume the obligations set forth in this Section 5.13.
 
     5.14 Tax-Free Reorganization.  Allegro and SPC will each use its
commercially reasonable efforts to cause the Merger to be treated as a
reorganization within the meaning of Section 368 of the Code. Allegro and SPC
will each make available to the other party and their respective legal counsel
copies of all returns requested by the other party.
 
     5.15 NASDAQ Listing.  Allegro agrees to apply for authorization for listing
on the Nasdaq SmallCap Market the shares of Allegro Common Stock issuable, and
those required to be reserved for issuance, in connection with the Merger, upon
official notice of issuance, and will use its commercially reasonable efforts to
have its Common Stock authorized for listing on the Nasdaq National Market
System as soon as reasonably practicable.
 
     5.16 SPC Affiliate Agreement.  Set forth on the SPC Schedules is a list of
those persons who may be deemed to be, in SPC's reasonable judgment, affiliates
of SPC within the meaning of Rule 145 promulgated under the Securities Act (an
"SPC Affiliate"). SPC will provide Allegro with such information and documents
as Allegro reasonably requests for purposes of reviewing such list. SPC will use
its best efforts to deliver or cause to be delivered to Allegro prior to the
Closing Date from each SPC Affiliate an executed affiliate agreement in
substantially the form attached hereto as Exhibit A (the "SPC Affiliate
Agreement"), each of which will be in full force and effect as of the Effective
Time. Allegro will be entitled to place appropriate legends on the certificates
evidencing any Allegro Common Stock to be received by an SPC Affiliate pursuant
to the terms of this Agreement, and to issue appropriate stop transfer
instructions to the transfer agent for the Allegro Common Stock, consistent with
the terms of the SPC Affiliate Agreement.
 
     5.17 Board of Directors of Allegro.  The Board of Directors of Allegro will
take all actions necessary to cause the Board of Directors of Allegro,
immediately after the Effective Time, to consist of eleven persons, nine of whom
shall have served on the Board of Directors of Allegro immediately prior to the
Effective Time and two of whom shall have served on the Board of Directors of
SPC immediately prior to the Effective Time (one of whom shall be Fred Gibbons,
in Class III, and one of whom shall be designated by the SPC Board of Directors,
and is currently expected to be Miriam Frazer, in Class II). If, prior to the
Effective Time, any of the SPC or Allegro designees shall decline or be unable
to serve as an SPC or Allegro director, SPC (if such person was designated by
SPC) or Allegro (if such person was designated by Allegro) shall designate
another person to serve in such person's stead, which person shall be reasonably
acceptable to the other party.
 
     5.18 Loan Facility.  From the date hereof through the Effective Date or
earlier termination of the Agreement, SPC shall, upon request by Allegro, loan
up to $1,000,000 to Allegro. SPC shall not be required to loan more than
one-third of the maximum loan amount in any 30-day period, and the proceeds of
all loans shall be used only for working capital purposes; provided, however,
that no such loan shall be required to be made unless and until the fairness
opinions referred to in Sections 6.2(e) and 6.3(f) have been received or the
condition relating thereto waived. Any such loan shall be evidenced by a
promissory note with the following terms:
 
          (a) maturity on the tenth anniversary of the date of any loan;
 
                                      A-25
<PAGE>   218
 
          (b) in the event that this Agreement is terminated by Allegro, the
     note shall be converted into shares of Common Stock of Allegro at the Loan
     Conversion Price (as defined below);
 
          (c) in the event this Agreement is terminated by SPC, the note (less
     any amount payable by SPC to Allegro pursuant to Section 7.3(b) of this
     Agreement) shall be converted into shares of Common Stock of Allegro at the
     Loan Conversion Price; provided, however, that in the event that such
     termination shall result in a fee payable by Allegro to SPC pursuant to
     Section 7.3(c) of this Agreement, only one-half of the note shall be so
     converted and the remaining one-half shall be repayable at the same time
     and in the same manner as the fee payable pursuant to Section 7;
 
          (d) the note shall bear interest at a rate per annum equal to the
     prime rate plus 2%.
 
     As used herein, the term "Loan Conversion Price" shall mean 90% of the
average of the last reported sale prices of the Allegro Common Stock for the ten
trading days ending on the day immediately prior to the date of termination
leading to conversion of the loan(s).
 
     5.19 Fairness Opinions.  Each of SPC and Allegro shall use their best
efforts to obtain the fairness opinions referred to in Sections 6.2(e) and
6.3(e), respectively.
 
     5.20 SPC Employee Benefits.  Subject to being able to do so consistently
with applicable laws, after the Effective Date, Allegro will use its
commercially reasonable efforts to cause the Surviving Corporation to provide to
the employees of SPC employee benefits comparable to those under the existing
SPC plans generally available to SPC employees.

     covenant or agreement on the part of Allegro set forth in this Agreement,
     or if any representation or warranty of Allegro shall have become untrue in
     any material respect, in either case such that the conditions set forth in
     Section 6.2(a) or Section 6.2(b) would not be satisfied as of the time of
     such breach or as of the time such representation or warranty shall have
     become untrue, provided that if such inaccuracy in Allegro's

     through the exercise of its commercially reasonable efforts within fifteen
     (15) days of the time such representation or warranty shall have become
     untrue or such breach, then SPC may not terminate this Agreement under this

     exercise such commercially reasonable efforts;
 
          (i) by Allegro, upon a material breach of any representation,
     warranty, covenant or agreement on the part of SPC set forth in this
     Agreement, or if any representation or warranty of SPC shall have become

     representations and warranties or breach by SPC is curable by SPC through
     the exercise of its commercially reasonable efforts within fifteen (15)
     days of the time such representation or warranty shall have become untrue
     or such breach, then Allegro may not terminate this Agreement under this
     Section 7.1(i) during such fifteen-day period provided SPC continues to
     exercise such commercially reasonable efforts;

     Effect with respect to SPC since the date of this Agreement;
 
          (l) by SPC, if the condition specified in Section 6.2(e) has not been
     satisfied by October 11, 1996; or

of the stockholders of SPC contemplated by this Agreement shall not have been

thereof (an "SPC Negative Vote") if prior to such SPC Negative Vote there shall
have occurred an Acquisition Proposal with respect to SPC which shall have been
publicly disclosed and not withdrawn; or (iii) in the event of an SPC Negative
Vote if prior to such SPC Negative Vote the Board of Directors of SPC shall have
withheld, withdrawn or modified in a manner adverse to Allegro its

     8.5 Entire Agreement.  This Agreement and the documents and instruments and
other agreements among the parties hereto as contemplated by or referred to

Board of Directors
Allegro New Media
3 Oak Road
Fairfield, NJ 07004
 
Gentlemen:
 
     We understand that Allegro New Media ("ANMI" or the "Company") and Software
Publishing Corporation ("SPC") are considering a transaction ("Transaction" or
"Merger") pursuant to which a newly formed wholly-owned subsidiary of ANMI
("Merger Sub") would merge with and into SPC and each of the outstanding shares
of common stock of SPC would be converted into the right to receive .26805 (the
"Exchange Ratio") shares of ANMI's common equity (the "Shares"). As of September
30, 1996, the application of this Exchange Ratio to SPC common equity
approximated 3,818,940 Shares.
 
     Upon the advice of ANMI and SPC and their accounting advisors, we have
assumed that the Merger will be treated as a purchase for accounting purposes.
We also have assumed that the pro forma financial statements of the combined
company provided to us are accurate and present fairly in all material respects
the combined financial position and results of ANMI and SPC and have been
prepared in accordance with generally accepted accounting principles.
 
     You have asked us to render our opinion (the "Opinion") as to whether the
Exchange Ratio is fair, from a financial point of view, to the Company and its
stockholders.
 
     In arriving at our Opinion, we have made such reviews, analyses and
inquiries as we have deemed necessary and appropriate in the circumstances. In
the course of such activities, among other things, we have:
 
          1. Reviewed the Agreement and Plan of Reorganization among ANMI,
     Merger Sub and SPC, dated as of October 1, 1996, and certain related
     documents.
 
          2. Discussed with senior management of ANMI and SPC their respective
     views of the strategic rationale for the Merger and the benefits of the
     Merger to ANMI.
 
          3. Participated in discussions and negotiations among representatives
     of ANMI and SPC and their financial and legal advisors.
 
          4. Reviewed the Form 10-K annual reports of SPC for the fiscal years
     ended September 30, 1993, 1994 and 1995, and the Form 10-KSB annual report
     of ANMI for the fiscal year ending December 31, 1995.
 
          5. Reviewed the audited annual financial statements of SPC for the
     fiscal years ended September 30, 1993, 1994 and 1995, and for ANMI for the
     fiscal years ending December 31, 1994 and 1995.
 
          6. Reviewed the Form 10-Q quarterly reports of SPC for the three
     months ended December 31, 1995, the six months ended March 31, 1996 and the
     nine months ended June 30, 1996.
 
          7. Reviewed the Form 10-QSB quarterly reports of ANMI for the three
     months ended March 31, 1996 and the six months ended June 30, 1996.
 
                                       B-1
<PAGE>   226
 
          8. Reviewed the ANMI prospectus dated December 6, 1995.
 
          9. Analyzed certain internal financial statements and other financial
     and operating data concerning ANMI prepared by the management of ANMI.
 
          10. Analyzed certain internal financial statements and other financial
     and operating data concerning SPC prepared by the management of SPC.
 
          11. Discussed the past and current operations and financial condition
     and the prospects of ANMI and SPC with senior executives of each.
 
          12. Analyzed certain financial projections prepared by SPC for the
     fiscal year ended September 30, 1996, the three month period ending
     December 31, 1996, and for the fiscal years ending September 30, 1997
     through 1999.
 
          13. Analyzed certain financial projections prepared by ANMI for the
     quarter ending September 30, 1996, the fiscal year ending December 31, 1996
     and the fiscal year ending December 31, 1997.
 
          14. Reviewed the analysis prepared by KPMG on the "Allocation of
     Purchase Price to Acquired Assets" relating to the proposed merger.
 
          15. Analyzed certain financial projections prepared by ANMI regarding
     the combined entity post-Merger for the fiscal year ended December 31,
     1997, and discussed with management of SPC and ANMI such financial
     projections and their underlying assumptions.
 
          16. Reviewed certain financial and securities data of companies deemed
     similar to SPC and ANMI; such review included, among other things, an
     analysis of historical financial performance, scope of operations, capital
     structure and market valuations of those companies relative to both ANMI
     and SPC.
 
          17. Reviewed the financial terms, to the extent publicly available, of
     certain selected acquisition transactions completed between January 1994
     and September 1996 involving companies engaged in the development and
     publishing of business productivity software.
 
          18. Reviewed the trading activity in ANMI and SPC's common stock in
     the past 12 months.
 
          19. Reviewed research reports prepared by securities analysts of major
     brokerage and investment banking firms for both ANMI and SPC.
 
          20. Reviewed various press releases on SPC and ANMI.
 
          21. Reviewed the external technology report titled "ASAP Product
     Technical Assets Evaluation" dated September 20, 1996.
 
          22. Conducted such other studies, analyses and investigations as we
     have deemed appropriate.
 
     In connection with our review, we have not independently verified the
information described above and for purposes of this Opinion have assumed the
accuracy, completeness and fairness thereof. We have further relied upon the
assurances of the management of ANMI and SPC that the information provided to us
by ANMI and SPC has been prepared on a reasonable basis, and, with respect to
projections, financial planning data, products under development, potential
publishing or distribution relationships, and other business outlook
information, reflects the best currently available estimates and judgments of
such respective management, and that they are not aware of any information or
facts that would make the information provided to us incomplete or misleading.
We have not performed any appraisals or valuations of specific assets,
liabilities, properties or facilities of ANMI or SPC. Our Opinion also relies
upon, without independent verification, ANMI management's assessment of the
validity of, and the risks associated with, SPC's products and technology.
 
     For our services in rendering this Opinion, ANMI will pay us a fee and
indemnify us against certain liabilities. This fee is not contingent upon
consummation of the Merger. Frost Capital Partners has also acted as financial
advisor to ANMI in connection with the Merger and will receive a fee for such
advisory services, payment of a significant portion of which is contingent upon
the consummation of the Merger. Approximately
 
                                       B-2
<PAGE>   227
 
fifty percent of the fees to be paid by ANMI to us will be in the form of ANMI
stock. Frost Capital Partners currently owns 14,181 shares and 25,000 options
with an exercise price of $3.25 of ANMI stock received as payment for a previous
transaction in which we acted as financial advisor.
 
     Our Opinion herein is as of September 30, 1996, the date upon which we
completed our review, analysis and inquiries as described above, and we have not
undertaken and disclaim any obligation to undertake any such review, analysis or
inquiry subsequent to that date.
 
     This Opinion is intended solely for the use of the Board of Directors in
connection with the matters contemplated hereby. This Opinion shall not be used
without our written consent, which we agree shall not be unreasonably withheld,
for any other purpose or reproduced, disseminated, quoted or referred to at any
time, in any manner, or for any purpose, other than as required by law or by
legal process. This Opinion is not intended to be and does not constitute a
recommendation to any stockholder as to how a stockholder should vote with
respect to the Merger.
 
     Based upon and subject to the foregoing and based on such other factors as
we consider relevant, it is our Opinion that the Exchange Ratio proposed to be
paid by ANMI in the Merger is fair, from a financial point of view, to ANMI and
its stockholders as of the date hereof.
 
Very truly yours,
 
FROST CAPITAL PARTNERS, INC.

Dear Ladies and Gentlemen:
 
     We understand that Software Publishing Corporation ("Software Publishing"
or the "Company") and Allegro New Media ("Allegro") have entered into an
Agreement and Plan of Merger, dated October 1, 1996 (the "Merger Agreement"),
pursuant to which Software Publishing will become a wholly owned subsidiary of
Allegro (the "Merger"). In connection with the Merger, Allegro will issue
0.26805 shares of its Common Stock for each share of Software Publishing's
Common Stock (the "Exchange Ratio") and the vested and non-vested options will
be assumed by Allegro based on the terms of the Merger.
 
     You have requested our opinion with respect to the fairness of the Exchange
Ratio, from a financial point of view, to the shareholders of Software
Publishing.
 
     In connection with our review, we have, among other things:
 
          (i) reviewed the Merger Agreement dated October 1, 1996;
 
          (ii) reviewed publicly available financial information with respect to
     the business operations of the Company including, but not limited to,
     audited financial statements for the fiscal years ended September 1993,
     1994 and 1995 and unaudited financial statements for the period ended June
     30, 1996;
 
          (iii) reviewed publicly available financial information with respect
     to the business operations of Allegro including, but not limited to,
     audited financial statements for the fiscal year ended December 31, 1995
     and unaudited financial statements for the period ended June 30, 1996;
 
          (iv) reviewed certain internal financial and operating information
     relating to Software Publishing and Allegro (including financial
     projections) prepared by the respective managements of each company;
 
          (v) held discussions with certain members of both Software Publishing
     and Allegro senior management concerning their past and current operations,
     financial condition and business prospects and the potential financial
     effect of the Merger of Software Publishing and Allegro if the Merger were
     consummated;
 
          (vi) reviewed a comparison of operating results and other financial
     information of Software Publishing and Allegro with other companies which
     we deemed appropriate;
 
          (vii) reviewed the historical market prices and reported trading
     activity of Software Publishing and Allegro Common Stock;
 
          (viii) compared the financial terms of the Merger and the premium paid
     over the Company's current, historical and average stock price with the
     terms and premiums paid of certain other merger, acquisition and business
     combination transactions which we deemed appropriate; and
 
          (ix) considered such other information, financial studies and analyses
     as we deemed relevant and performed such analyses, studies and
     investigations as we deemed necessary.
 
                                       C-1

     We have assumed and relied upon, without independent verification, the
accuracy and completeness of the information reviewed by us. With respect to any
financial projections, we assumed that they had been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
respective future financial performances of Software Publishing and Allegro and
the future financial performance of the combined company. We also have assumed,
without independent verification, that Allegro owns and has adequate legal
protection for all material intellectual property it purports to own, that
Allegro owns or has adequate rights to use all intellectual property material to
its business as conducted or contemplated to be conducted and that the
representations and warranties of Software Publishing and Allegro in the
Agreement and Plan of Reorganization are true and correct. We have also assumed
that the Merger will be accounted for as a purchase.
 
     We have not conducted a physical inspection of the properties or facilities
of Software Publishing or Allegro or made any independent valuation or appraisal
of the assets, liabilities, patents or intellectual property of Software
Publishing and Allegro, nor have we been furnished with any such valuations or
appraisals. Our opinion is necessarily based upon economic, market and other
conditions as in effect on, and the information made available to us, as of the
date of this letter.
 
     We understand that in considering the Merger, the Board of Directors of the
Company has considered a wide range of financial and non-financial factors, many
of which are beyond the scope of this letter. This letter is not intended to
substitute for the Board's exercise of its own business judgment in reviewing
the Merger. This opinion is solely for purposes of the Board of Directors of the
Company in connection with its exercise of its business judgment, and delivery
of this opinion is not intended to confer rights on any third party, including
shareholders, employees or creditors of the Company or Allegro.
 
     We are expressing no opinion herein as to the prices at which the shares of
the Company or Allegro will actually trade at any time. Our opinion does not
constitute a recommendation to any shareholder as to how such shareholder should
vote on the Merger. It should be understood that, although subsequent
developments may occur which might affect this opinion, Unterberg Harris does
not have any obligation to update, revise or reaffirm this opinion.
 
     Based upon and subject to the foregoing considerations, it is our opinion
as financial advisors that, as of the date of the Merger Agreement, the Exchange
Ratio is fair, from a financial point of view, to the shareholders of Software
Publishing.
 
                                          Very truly yours,

                        DELAWARE GENERAL CORPORATION LAW
 
SECTION 262 -- APPRAISAL RIGHTS.
 
     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec.228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of his shares of stock under the circumstances described in
subsections (b) and (c) of this section. As used in this section, the word
"stockholder" means a holder of record of stock in a stock corporation and also
a member of record of a nonstock corporation; the words "stock" and "share" mean
and include what is ordinarily meant by those words and also membership or
membership interest of a member of a nonstock corporation; and the words
"depository receipt" mean a receipt or other instrument issued by a depository
representing an interest in one or more shares, or fractions thereof, solely of
stock of a corporation, which stock is deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec.251, 252, 254, 257, 258, 263 or 264 of this title:
 
          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the holders of the surviving corporation as
     provided in subsections (f) or (g) of sec.251 of this title.
 
          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:
 
             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;
 
             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock or depository receipts at the
        effective date of the merger or consolidation will be either listed on a
        national securities exchange or designated as a national market system
        security on an interdealer quotation system by the National Association
        of Securities Dealers, Inc. or held of record by more than 2,000
        holders;
 
             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or
 
             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.
 
          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec.253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.
 
                                       D-1
<PAGE>   231
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or
 
          (2) If the merger or consolidation was approved pursuant to sec.228 or
     253 of this title, the surviving or resulting corporation, either before
     the effective date of the merger or consolidation or within 10 days
     thereafter, shall notify each of the stockholders entitled to appraisal
     rights of the effective date of the merger or consolidation and that
     appraisal rights are available for any or all of the shares of the
     constituent corporation, and shall include in such notice a copy of this
     section. The notice shall be sent by certified or registered mail, return
     receipt requested, addressed to the stockholder at his address as it
     appears on the records of the corporation. Any stockholder entitled to
     appraisal rights may, within 20 days after the date of mailing of the
     notice, demand in writing from the surviving or resulting corporation the
     appraisal of his shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of his shares.
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of
 
                                       D-2
<PAGE>   232
 
their shares have not been reached by the surviving or resulting corporation. If
the petition shall be filed by the surviving or resulting corporation, the
petition shall be accompanied by such a duly verified list. The Register in
Chancery, if so ordered by the Court, shall give notice of the time and place
fixed for the hearing of such petition by registered or certified mail to the
surviving or resulting corporation and to the stockholders shown on the list at
the addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall
 
                                       D-3
<PAGE>   233
 
be dismissed as to any stockholder without the approval of the Court, and such
approval may be conditioned upon such terms as the Court deems just.
 
     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.
 
                                       D-4

                                                                         ANNEX E
 
     If Proposal 2 is approved, the following will be included in an amendment
to the Certificate of Incorporation of the Company, in Article FOURTH thereof:
 
FOURTH: (a) The total number of shares of all classes of stock which the
Corporation shall have authority to issue is THIRTY-FOUR MILLION (34,000,000)
shares. Of these (i) THIRTY MILLION (30,000,000) shares shall be shares of
Common Stock of the par value of $.001 per share; (ii) TWO MILLION (2,000,000)
shares shall be shares of Class A Convertible Preferred Stock; (iii) ONE MILLION
NINE HUNDRED THIRTY-NINE THOUSAND FOUR HUNDRED EIGHTY (1,939,480) shares shall
be shares of Serial Preferred Stock of the par value of $.001 per share; and
(iv) SIXTY-THOUSAND FIVE HUNDRED TWENTY (60,520) shares shall be shares of Class
B Voting Preferred Stock, Series A of the par value of $.001 per share. [If
Proposal 3 is approved, to read "The total number of shares of all classes of
stock which the Corporation shall have authority to issue is THIRTY-TWO MILLION
(32,000,000) shares. Of these (i) THIRTY MILLION (30,000,000) shares shall be
shares of Common Stock of the par value of $.001 per share; (ii) ONE MILLION
NINE HUNDRED THIRTY-NINE THOUSAND FOUR HUNDRED EIGHTY (1,939,480) shares shall
be shares of Serial Preferred Stock of the par value of $.001 per share; and
(iii) SIXTY-THOUSAND FIVE HUNDRED TWENTY (60,520) shares shall be shares of
Class B Voting Preferred Stock, Series A of the par value of $.001 per share."]
[If Proposals 2 and 3 are not approved to read: "The amount of the total
authorized capital stock of this Corporation is TWENTY-TWO MILLION (22,000,000)
shares. Of these (i) EIGHTEEN MILLION (18,000,000) shares shall be shares of
Common Stock of the par value of $.001 per share; (ii) TWO MILLION (2,000,000)
shares shall be shares of Class A Convertible Preferred Stock; and (iii) TWO
MILLION (2,000,000) shares shall be shares of Serial Preferred Stock of the par
value of $.001 per share."]
 
     (b) The statement of the relative rights, preferences and limitations of
the shares of each class is as follows:
 
     A. Class A Convertible Preferred Stock.
 
     1. Dividends.  Each issued and outstanding share of Class A Convertible
Preferred Stock shall entitle the holder of record thereof to receive out of
funds legally available therefor, when, as and if declared by the Board of
Directors, dividends accruing at the annual rate of ten percent (10%) of the
liquidation preference thereof, commencing December 1, 1994, which shall be
payable only on such date as the shares of Class A Convertible Preferred Stock
are redeemed pursuant to paragraph 3 below or the Company is liquidated,
dissolved or wound up in accordance with paragraph 2 below. Whenever any full
dividends which have been declared upon the issued and outstanding shares of
Class A Convertible Preferred Stock as aforesaid for all past annual periods
shall have been paid, without interest, and whenever full dividends upon the
issued and outstanding shares of Class A Convertible Preferred Stock as
aforesaid for the then current annual dividend period shall have been declared
and either paid or a sum sufficient for the payment thereof set aside in full,
without interest, the Board of Directors may declare, set aside, or pay
additional cash dividends on each share of Common Stock.
 
     2. Liquidation.  In the event of any liquidation, dissolution, or winding
up of the affairs of the Corporation, whether voluntary or involuntary, each
issued and outstanding share of Class A Convertible Preferred Stock shall
entitle the holder of record thereof to payment at the rate per share of $1.00
before any payment or distribution of the net assets of the Corporation shall be
made to or set apart for the holders of record of the issued and outstanding
Common Stock in respect of said Common Stock. After setting apart or paying in
full the preferential amounts aforesaid to the respective holders of record of
the issued and outstanding Class A Convertible Preferred Stock, the remaining
net assets, if any, shall be distributed exclusively to the holders of record of
the issued and outstanding Common Stock, each issued and outstanding share of
Common Stock entitling the holder of record thereof to receive an equal
proportion of said remaining net assets. If the net assets of the Corporation
shall be insufficient to pay in full the preferential amounts to which the
holders of record of all the outstanding shares of Class A Convertible Preferred
Stock are respectively entitled as aforesaid, the entire net assets of the
Corporation shall be distributed ratably to the holders of all the outstanding
shares of Class A Convertible Preferred Stock in proportion to the full amounts
 
                                       E-1
<PAGE>   235
 
to which they are respectively entitled, and the holders of the Common Stock
shall in no event be entitled to participate in the distribution of said net
assets in respect of their Common Stock. Without excluding any other proceeding
which does not in fact effect a liquidation, dissolution, or winding up of the
Corporation, a merger or consolidation of the Corporation into or with any other
corporation, a merger of any other corporation into the Corporation, or a sale,
lease, mortgage, pledge, exchange, transfer or other disposition by the
Corporation of all of substantially all of its assets shall not be deemed, for
the purposes of this paragraph, to be a liquidation, dissolution, or winding up
of the Corporation.
 
     3. Redemption.  (a) At any time after December 1, 1996, if no Exit Event
(as defined below) has occurred, the holders of record of a majority of the
shares of Class A Convertible Preferred Stock shall have the right to require
the Company to redeem all of the issued and outstanding shares of Class A
Convertible Preferred Stock by paying the holders of record thereof, out of
funds legally available therefor, an amount equal to the sum of (i) $1.00 per
share to be redeemed, plus (ii) an amount equal to all accrued and unpaid
dividends which have been declared on each such share to be redeemed (said sum
being hereafter referred to as the "Redemption Price"). The holders of record of
at least a majority of the shares of Class A Convertible Preferred Stock may
exercise such right only by sending the Corporation written notice of their
exercise of such right, which notice shall be signed by the holders of record of
at least a majority of the issued and outstanding shares of Class A Convertible
Preferred Stock. Promptly after the receipt of such notice, the Corporation
shall mail to each holder of record of shares of Class A Convertible Preferred
Stock at his address as it appears on the Corporation's records of stockholders
a notice fixing the date (on a date within 90 days of the date of receipt of the
notice from the holders of the Class A Preferred Stock), time and place of
redemption of all the issued and outstanding shares of Class A Convertible
Preferred Stock. On such date, time and place, the Corporation shall, through
its Board of Directors and in conformity with the provisions of the Delaware
General Corporation Law, redeem all of the issued and outstanding shares of
Class A Convertible Preferred Stock by paying the holders of record thereof, out
of funds legally available therefor, the Redemption Price for each share
redeemed pursuant to subparagraph (d) of this paragraph 3. From and after the
date fixed by the Corporation for such redemption (the "Redemption Date"),
unless default shall be made by the Corporation in providing the funds for
redemption, dividends on the Class A Convertible Preferred Stock shall cease to
accrue and said shares shall no longer be deemed to be outstanding, and all
rights of the holders thereof in respect of such shares shall cease as of the
Redemption Date except the right to receive the Redemption Price payable upon
surrender of certificates representing such shares.
 
     For these purposes, an "Exit Event" shall mean (i) the Common Stock being
listed ("Listed") for trading on the New York Stock Exchange, the American Stock
Exchange (including the emerging company market), or the National Association of
Securities Dealers, Inc. Automated Quotation System (on the national market
system or the small capitalization market, or any successor thereto, but not
including the Bulletin Board), (ii) the sale of a majority or substantially all
of the Company's assets or a majority of the capital stock of the Company in an
all cash and/or capital stock transaction or to a non-affiliated purchaser which
has a class of capital stock that is Listed; provided, that if all or any part
of the purchase price is paid in securities which are not Listed, then the
holders of shares of Class A Convertible Preferred Stock shall be entitled to be
paid in cash unless M.S. Farrell & Co., Inc. in its sole discretion, consents to
such holders being paid on the same basis as the remaining shareholders of the
Company; or (iii) the sale of a majority or substantially all of the assets or a
majority of the capital stock of the Company to a non-affiliated purchaser which
does not have a class of capital stock that is Listed in a transaction that is
not for all cash and either M.S. Farrell & Co., Inc. and the holders of shares
of Class A Convertible Preferred Stock have been paid entirely in cash or M.S.
Farrell & Co., Inc. has, in its sole discretion, consented to such holders being
paid on the same basis as the remaining shareholders of the Company.
 
     (b) Any shares of Class A Convertible Stock redeemed pursuant to this
paragraph, or otherwise acquired by the Corporation in any manner whatsoever,
shall be permanently retired immediately on the acquisition thereof and shall
not, under any circumstances, be reissued, sold or transferred by the
Corporation; and the Corporation may, from time to time, take appropriate action
to reduce the authorized number of shares of the Class A Convertible Preferred
Stock accordingly.
 
                                       E-2
<PAGE>   236
 
     (c) Any monies set aside by the Corporation for the payment of the
Redemption Price of Class A Convertible Preferred Stock which shall remain
unclaimed by the holders of the shares of Class A Convertible Preferred Stock
entitled thereto at the end of six (6) years after the Redemption Date, together
with any interest thereon which shall be allowed by any bank or trust company
with which such moneys may have been deposited during such time by the
Corporation, shall, subject to applicable law, be paid to the Corporation and
shall revert to the treasury of the Corporation and be available for general
corporate purposes as if never provided by the Corporation for the payment of
the Redemption Price for shares of Class A Convertible Preferred Stock;
provided, however, that thereafter such holders, if and when they shall make
claim therefor, shall be paid the applicable Redemption Price for such shares of
Class A Convertible Preferred Stock (but without interest thereon) from any
funds of the Corporation then available for that purpose.
 
     (d) In the event of a redemption pursuant to this paragraph 3, the Company
shall pay to the holders of record of shares of Class A Convertible Preferred
Stock the Redemption Price therefor in equal quarterly installments over the
three-year period subsequent to the Redemption Date; provided that if an Exit
Event occurs within such three-year period, each of the former holders of shares
of Class A Convertible Preferred Stock which have been so redeemed shall have
the right to repurchase all of their previously held shares of Class A
Convertible Preferred Stock (and to convert such shares of Class A Convertible
Preferred Stock into shares of Common Stock on the same basis as set forth
below) for a price equal to the Redemption Price plus interest at a rate equal
to 10% per annum for the period from the Redemption Date to the date of
repurchase.
 
     4. Conversion.  (a) Subject to any conditions herein contained, upon the
shares of Common Stock becoming Listed, all of the shares of Class A Convertible
Preferred Stock of the Corporation shall be automatically converted into fully
paid and nonassessable shares of Common Stock of the Corporation. Upon receipt
by the Corporation or its designee of surrendered certificate or certificates
representing the shares of Class A Convertible Preferred Stock to be converted,
with any appropriate endorsement thereon, as may be prescribed by the Board of
Directors, such holder shall be entitled to receive a certificate or
certificates representing the shares of Common Stock into which such share(s) of
Class A Convertible Preferred Stock are converted, and such holder shall be
deemed to be a holder of record of said shares of Common Stock, and no longer a
holder of such shares of Class A Convertible Preferred Stock to be so converted,
as of the time of such automatic conversion. The basis for such conversion shall
be the "conversion rate" in effect at the time of conversion, which for the
purposes hereof, shall mean the number of shares of Common Stock issuable for
each share of Class A Convertible Preferred Stock surrendered for conversion.
The conversion rate shall be 2.42 shares of Class A Convertible Preferred Stock
for each share of Common Stock obtainable upon conversion; provided that if the
Common Stock becomes Listed on or prior to October 1, 1995, the conversion rate
shall equal a rate equal to one share of Common Stock for such number of shares
of Class A Convertible Preferred Stock as shall have a liquidation preference
equal to the lesser of (a) one-half of the price per share of Common Stock in
the initial public offering of shares of Common Stock, or if there has been no
initial public offering of shares of Common Stock, one-half of the closing price
per share of Common Stock on the first day on which it is traded after becoming
Listed, or (b) $3.00. In connection with effecting any transfer to the
Corporation for cancellation of any shares of Class A Convertible Preferred
Stock upon conversion of the same into Common Stock, the Corporation may, but
shall not be obliged to, issue a certificate or certificates for fractions of a
share of Common Stock. If the Corporation elects not to issue a certificate or
certificates for fractions of a share of Common Stock, the Corporation shall pay
in lieu thereof an amount equal to the conversion price of such fractional share
(computed to the nearest one hundredth of a share) in effect at the close of
business on the date of conversion. Any shares of Class A Convertible Preferred
Stock which have been converted shall be cancelled and shall be restored to the
status of authorized but unissued shares of Class A Convertible Preferred Stock.
Except as such requirement may otherwise be dispensed with by law, the
Corporation shall at all times reserve and keep available, out of its authorized
and unissued stock, solely for the purpose of effecting the conversion of shares
of the Class A Convertible Preferred Stock, such number of shares of Common
Stock as shall from time to time be sufficient to effect the conversion of all
shares of the Class A Convertible Preferred Stock from time to time outstanding.
 
                                       E-3
<PAGE>   237
 
     (b) The number of shares of Common Stock into which each share of Class A
Convertible Preferred Stock is convertible shall be subject to adjustment from
time to time only as follows:
 
          (A) In case the Corporation shall at any time or from time to time
     issue (other than in a stock dividend or subdivision or combination to
     which subparagraph (D) of the paragraph 4(b) shall be applicable) or sell
     any shares of its Common Stock (including shares now or hereafter held in
     the treasury), without consideration or for a consideration per share less
     than the "conversion price" (as hereinafter defined), then immediately upon
     such issuance or sale, the conversion rate shall be reduced to a rate
     determined by dividing (i) an amount equal to the arithmetic sum of (x) the
     number of shares of Common Stock outstanding immediately prior to such
     issuance or sale (excluding shares held in the treasury), multiplied by the
     conversion rate then in effect, plus (y) the aggregate of the amounts of
     all consideration, if any, received by the Corporation upon such issuance
     or sale by (ii) the number of shares of Common Stock outstanding
     immediately after such issuance or sale; provided that there shall be
     excluded from the foregoing computation all shares issued (and the
     consideration received for such shares): (1) upon the conversion of any
     shares of Class A Convertible Preferred Stock, but not including within
     this exception any shares of Class A Convertible Preferred Stock which may
     be reissued following redemption or repurchase or may be otherwise
     reissued; (2) which are issuable pursuant to the Corporation's 1994 Long
     Term Incentive Plan; (3) pursuant to the exercise of the Warrants issued as
     of December 23, 1993 to M.S. Farrell & Co., Inc., Neil M. Kaufman, Harvey
     R. Blau, Edward I. Kramer, David H. Lieberman and Edward S. Wactlar
     (collectively, the "Warrants"); and (4) which were issued, in a stock
     dividend or in a subdivision to which subparagraph (D) shall be applicable,
     with respect to shares described in the foregoing clauses (1), (2) and (3).
     As used herein, the term "conversion price" shall be an amount computed by
     multiplying the conversion rate then in effect by $1.00. Upon each
     adjustment of the conversion rate under the provisions of this subparagraph
     (A) or said subparagraph (D) of this paragraph 4(b), the conversion price
     shall be correspondingly adjusted.
 
          (B) No reduction of the conversion price shall be made if the amount
     of any such reduction would be an amount less than $.01, but any such
     amount shall be carried forward and reduction with respect thereto shall be
     made at the time of and together with any subsequent reduction which,
     together with such amount and any other amount or amounts so carried
     forward, shall aggregate $.03 or more.
 
          (C) For the purposes of subparagraph (A) of this paragraph 4(b), the
     following provisions (1) through (5), inclusive, also shall be applicable:
 
             (1) In case of the issue of any shares of Common Stock for (a)
        cash, the consideration received by the Corporation therefor shall be
        deemed to be the amount of cash received by the Corporation for such
        shares; or (b) consideration other than cash, the value of such
        consideration shall be deemed to be the fair market value thereof as of
        the date of adoption of the resolution authorizing such transaction, as
        determined by the Board of Directors at or as of such date.
 
             (2) In case the Corporation shall grant or issue any rights to
        subscribe to, or options or warrants to purchase, any shares of its
        Common Stock at a price per share less than the conversion price then in
        effect (other than pursuant to its 1994 Long Term Incentive Plan or the
        rights, options and warrants referred to in subparagraph (C)(3) of this
        paragraph 4(b)), the conversion rate hereunder shall be adjusted in the
        manner and to the extent provided in subparagraph (A) of this paragraph
        4(b) as though all the shares of Common Stock called for by such rights,
        options or warrants had been then issued and sold for the then
        applicable aggregate subscription or purchase price payable to the
        Corporation upon exercise of, and provided for in, such rights, options
        or warrants plus the amount, if any, paid or payable to the Corporation
        as consideration for the granting of such rights, options or warrants.
        For purposes of determining whether the aforesaid price per share of
        Common Stock is less than the conversion price then in effect, the price
        per share of Common Stock shall be determined by dividing (a) an amount
        equal to the arithmetic sum of (x) such aggregate subscription or
        purchase price plus (y) the consideration, if any, paid or payable for
        the granting of such rights, options or warrants by (b) the aggregate
        number of shares of Common Stock called for by such rights, options or
        warrants. Upon the expiration of such rights, options, or
 
                                       E-4
<PAGE>   238
 
        warrants, the conversion rate shall then be recalculated in accordance
        with the provisions of subparagraph (A) of this paragraph 4(b) as though
        all the shares of Common Stock which were issued pursuant to the
        exercise of such options, rights and warrants had been sold at such date
        of expiration at the aggregate purchase price actually received by the
        Corporation; provided, however, that no such recalculation shall be made
        if as a result thereof there would be a decrease in the conversion rate
        below the conversion rate which would have been in effect had such
        rights, options or warrants never been issued.
 
             (3) In case the Corporation shall issue any security which is
        convertible into or exchangeable for its Common Stock (other than the
        Warrants and shares of Class A Convertible Preferred Stock, but not
        including within this exception any shares of Class A Convertible
        Preferred Stock which may be reissued after redemption or acquisition or
        may be otherwise reissued), entitling the holders thereof to convert
        such security at a price per share of Common Stock less than the
        conversion price then in effect, such issue of such other convertible or
        exchangeable security shall be deemed, for the purpose of paragraph (A)
        of this paragraph 4(b), to be an issue of an aggregate number of shares
        of Common Stock equal to the number of shares of Common Stock into which
        such other security is then convertible or exchangeable and for an
        aggregate consideration, if any, equal to the amount of consideration
        for which such other security is so issued by the Corporation plus the
        amount, if any, then payable to the Corporation upon conversion or
        exchange of such security and from and after the date of issue of such
        other security, any adjustment in the conversion rate hereunder shall be
        made in the manner and to the extent provided in subparagraph (A) of
        this paragraph 4(b). For the purposes of determining whether the holders
        of such security are entitled to convert same at a price per share of
        Common Stock less than the conversion price then in effect, such price
        per share of Common Stock shall be determined by dividing (a) an amount
        equal to the arithmetic sum of (x) the aggregate consideration, if any,
        for which such other security is so issued by the Corporation plus (y)
        the aggregate amount, if any, then payable to the Corporation upon such
        conversion or exchange of such security by (b) the aggregate number of
        shares of Common Stock into which other security is then convertible or
        exchangeable. Upon the expiration of the right to convert such other
        convertible security, or upon the redemption or other repurchase or
        retirement of any shares or other instruments of such other convertible
        security, the conversion rate shall then be recalculated in accordance
        with the provisions of subparagraph (A) of this paragraph 4(b) as though
        all the shares of Common Stock which were issued upon conversion of such
        other convertible security had been sold at the date of expiration of
        such right to convert at the aggregate purchase price actually received
        by the Corporation; provided, however, that no such recalculation shall
        be made if as a result thereof there would be a decrease in the
        conversion rate below the conversion rate which would have been in
        effect had such other convertible security never been sold.
 
             (4) For the purpose of determining the amount of consideration
        received by the Corporation for the issue of shares of Common Stock or
        for obligations or securities of the Corporation converted into or
        exchanged for shares of Common Stock as specified in the foregoing
        subparagraphs (1) through (3) of this subparagraph 4(b)(C), deduction
        shall be made for such compensation or discount in the sale,
        underwriting, or purchase of such obligations or securities by
        underwriters or dealers or others performing similar services or for
        such expenses incurred in connection therewith as may be paid or allowed
        by the Corporation.
 
             (5) In case the Corporation shall issue any shares of Common Stock
        as a dividend or make any other distribution upon its Common Stock in
        Common Stock, the aggregate number of shares of Common Stock issued in
        payment of such dividend or distribution shall be deemed to have been
        issued without consideration.
 
             (6) The terms "issue" and "issued", as used herein, shall include
        the transfer and delivery of treasury shares by the Corporation.
 
          (D) (1) In case shares of Common Stock are issued as a dividend or
     other distribution on the Common Stock, the conversion price in effect at
     the opening of business on the business day next
 
                                       E-5
<PAGE>   239
 
     succeeding the date fixed for the determination of the holders of Common
     Stock entitled to receive such dividend or other distribution shall be
     decreased to an amount equal to the conversion price so in effect
     multiplied by a fraction, the numerator of which shall be the number of
     shares of Common Stock issued and outstanding at the close of business on
     the date fixed for such determination and the denominator of which shall be
     the sum of said number of shares issued and outstanding at the close of
     business on the date fixed for such determination and the number of shares
     constituting such dividend or other distribution, such decrease becoming
     effective immediately after the opening of business on the business day
     next succeeding the date fixed for such determination. The Corporation will
     not pay any dividend or make any distribution on the Common Stock held in
     the treasury of the Corporation.
 
          (2) In case outstanding shares of Common Stock shall be subdivided
     into a greater number of shares or outstanding shares shall be combined
     into a smaller number of shares, the conversion price in effect at the
     opening of business on the business day next succeeding the day upon which
     such subdivision or combination becomes effective shall be decreased or
     increased, as the case may be, to an amount equal to the conversion price
     so in effect multiplied by a fraction, the numerator of which shall be the
     number of shares outstanding immediately before such subdivision or
     combination becomes effective and the denominator of which shall be the
     number of shares outstanding at the opening of business on the business day
     next succeeding the day upon which such subdivision or combination becomes
     effective, such increase or decrease becoming effective immediately after
     the opening of business on the business day next succeeding the day upon
     which such subdivision or combination becomes effective.
 
          (3) If the Corporation shall issue any securities by recapitalization
     or reclassification of the Common Stock, each share of Common Stock into
     which a share of the Class A Convertible Preferred Stock may immediately
     prior thereto be converted shall be replaced for the purposes hereof by the
     securities issuable or distributable in respect to each such share of
     Common Stock upon such recapitalization or reclassification and appropriate
     adjustment of the conversion rate in effect immediately prior to such
     recapitalization or reclassification shall be made, such adjustment to
     become effective immediately after the opening of business on the day on
     which such recapitalization and reclassification shall become effective.
     If, as a result of an adjustment made pursuant to this subparagraph (D)(3),
     the holder of any Class A Convertible Preferred Stock thereafter
     surrendered for conversion shall become entitled to receive shares of two
     or more classes of capital stock or shares of Common Stock and other
     capital stock of the Corporation, such holders of the Class A Convertible
     Preferred Stock shall be entitled to receive such securities as would the
     holder of such number of shares of Common Stock as would at that time be
     obtainable upon conversion of such shares of Class A Convertible Preferred
     Stock into shares of Common Stock.
 
          (E) In case of any consolidation or merger of the Corporation with or
     into another corporation, or in case of any sale, lease, mortgage, pledge,
     conveyance or other disposition to another corporation of all or
     substantially all the property of the Corporation, each holder of a share
     of Class A Convertible Preferred Stock then outstanding and thereafter
     remaining outstanding shall have the right thereafter to convert each share
     held into the kind and amount of shares, other securities, cash and
     property receivable upon such transaction by a holder of the number of
     shares of Common Stock into which such shares of Class A Convertible
     Preferred Stock might have been converted immediately prior to such
     transaction; in any such event, effective provision shall be made, in the
     certificate of incorporation of the resulting or surviving corporation or
     otherwise, so that the provisions set forth herein for the protection of
     the conversion rights of the Class A Convertible Preferred Stock shall
     thereafter be applicable, as nearly as reasonably may be, to any such other
     shares, other securities, cash and property deliverable upon conversion of
     the shares of Class A Convertible Preferred Stock remaining outstanding or
     other convertible shares or securities received by the holders in place
     thereof, and any such resulting or surviving corporation shall expressly
     assume the obligation to deliver, upon the exercise of the conversion
     privilege, such shares, other securities, cash or property as the holders
     of the shares of Class A Convertible Preferred Stock remaining outstanding,
     or other convertible shares or securities received by the holders in place
     thereof, shall be entitled to receive pursuant to the provisions hereof,
     and to make provision for the protection of the conversion right as above
     provided.

<PAGE>   240
 
          (F) Whenever the conversion rate and conversion price are adjusted as
     herein provided, the Treasurer of the Corporation shall compute the
     adjusted conversion rate and conversion price in accordance with the
     foregoing provisions and shall prepare a written instrument setting forth
     such adjusted conversion rate and conversion price and showing in detail
     the facts upon which such adjustment is based, including a statement of the
     consideration received or to be received by the Corporation for any shares
     of Common Stock issued or deemed to have been issued and included in the
     computations of such adjustment, and such written instrument shall promptly
     be delivered to the holders of the Class A Convertible Preferred Stock.
 
          (G) In case: (i) the Corporation shall declare a dividend (or any
     other distribution) on the Common Stock payable otherwise than in shares of
     Common Stock or in cash out of its capital surplus; or (ii) of any
     reclassification of the capital stock of the Corporation (other than a
     subdivision or combination of outstanding shares of Common Stock), or of
     any consolidation or merger to which the Corporation is a party or of the
     sale, lease, mortgage, pledge, conveyance or other disposition of all or
     substantially all of the property of the Corporation; or (iv) of the
     voluntary or involuntary dissolution, liquidation or winding up of the
     Corporation; then the Corporation shall cause to be mailed to the record
     holders of the Class A Convertible Preferred Stock at least twenty (20)
     days prior to the applicable record date hereinafter specified, a notice
     stating (x) the date on which a record is to be taken for the purpose of
     such dividend, distribution or rights, or, if a record is not to be taken,
     the date as of which the holders of record of Common Stock to be entitled
     to such dividend, distribution or rights are to be determined or (y) the
     date on which such reclassification, consolidation, merger, sale, lease,
     mortgage, pledge, conveyance, other disposition, dissolution, liquidation
     or winding up is expected to become effective, and the date as of which it
     is expected that holders of record of Common Stock shall be entitled to
     exchange their shares of Common Stock for securities or other property
     deliverable upon such reclassification, consolidation, liquidation, merger,
     sale, lease, mortgage, pledge, conveyance, other disposition, dissolution,
     liquidation or winding-up.
 
          (H) The Corporation shall pay all issue taxes, if any, incurred in
     respect of the issue of shares of Common Stock on conversion. If a holder
     of shares surrendered for conversion specifies that the shares of Common
     Stock to be issued on conversion are to be issued in a name or names other
     than the name of names in which such surrendered shares stand, the
     Corporation shall not be required to pay any transfer or other taxes
     incurred by reason of the issuance of such shares of Common Stock to the
     name of another, and if the appropriate transfer taxes shall not have been
     paid to the Corporation or the transfer agent for the Class A Convertible
     Preferred Stock at the time of surrender of the shares involved, the shares
     of Common Stock issued upon conversion thereof may be registered in the
     name or names in which the surrendered shares were registered, despite the
     instructions to the contrary.
 
          (I) The reference to Common Stock herein shall be deemed to include
     shares of any class into which said Common Stock may be changed.
     Notwithstanding any provision of this certificate or incorporation or of
     law, by reason of which limited or unlimited preemptive rights are
     otherwise conferred upon the holders of any class of shares of the
     Corporation, no preemptive right shall accrue solely by reason of the
     issuance by the Corporation of shares in satisfaction of the conversion
     rights and privileges of the holders of the Class A Convertible Preferred
     Stock as aforesaid.
 
     5. Voting Rights.  (a) Except as expressly otherwise provided by law and as
set forth in paragraph 5(b) below, the holders of the Class A Convertible
Preferred Stock shall not be entitled to vote at any meeting of the stockholders
or to receive notice of such meeting, all voting rights to the fullest extent
permitted by law being vested exclusively in the holders of the Common Stock.
 
     (b) If and whenever any of the following events shall occur: (i) the
Corporation intends to or shall file a voluntary petition under the United
States Bankruptcy Code; (ii)'an involuntary petition thereunder shall have been
filed and remain undismissed for sixty (60) days; (iii) the Corporation takes
any other similar action for the benefit of creditors; or (iv) the Corporation
shall have failed to provide any of the weekly or monthly reports required under

period of five

<PAGE>   241
 
(5) business days after three (3) or more consecutive weekly periods or thirty
(30) days after any monthly period; (v) the Corporation shall have failed eight
or more times to provide the weekly and/or monthly reports required of Section
3.z of the Engagement Agreement; or (vi) the Corporation shall have failed to
comply with its obligations under Section 7 of the Engagement Agreement; then
the holders of record of the issued and outstanding shares of Class A
Convertible Preferred Stock, voting together as a separate class, shall, at the
annual meeting of the stockholders of the Corporation next held and at all
subsequent annual meetings, have the right to elect one member of the Board of
Directors and the size of the Board of Directors, as it then exists pursuant to
this Certificate or the By-Laws, shall be no greater than that permitted
pursuant to Section 7 of such engagement agreement. Except as provided below,
any Director elected by the holders of the Class A Convertible Preferred Stock
pursuant to this subparagraph may be removed and any vacancy in the directorship
created and existing at any time to give effect to the rights of the holders of
Class A Convertible Preferred Stock hereunder may be filled only by vote of the
holders of a majority of such Class A Convertible Preferred Stock.
 
     6. Sinking Fund.  No share of Class A Convertible Preferred Stock shall be
entitled to the benefit of any sinking fund or purchase fund to be applied to
the redemption or purchase thereof.
 
     B. Serial Preferred Stock.  The Serial Preferred Stock may be issued from
time to time in classes or series and shall have such voting powers, full or
limited, or no voting powers, and such designations, preferences and relative,
participating, optional or other special rights, and qualifications, limitations
or restrictions thereof, as shall be stated and expressed in the resolution or
resolutions of the Board of Directors providing for the issuance of such stock.
 
     1. Designation.  (a) The designation of the series of Serial Preferred

winding up of the Corporation, prior to the common stock, par value $.001 per
share, of the Corporation, and any other stock which by its terms ranks junior
to the Class B Preferred, and on a parity with all shares designated as
Corporation's Class A Convertible Preferred Stock.
 
     (c) Shares of the Class B Preferred that have been redeemed, purchased or
otherwise acquired by the Corporation shall not be reissued as Class B Preferred
and when retired as provided by the General Corporation Law of the State of
Delaware, shall have the status of authorized but unissued shares of Serial
Preferred Stock, without designation as to series until such shares are once
more designated as part of a particular series by the Board of Directors of the
Corporation or a duly authorized committee thereof.
 
     2. Dividends.  Each holder of shares of Class B Preferred (each a "Holder")
shall not be entitled to receive any dividends.
 
     3. Liquidation Rights.  (a) Upon the dissolution, liquidation or winding up
of the affairs of the Corporation, whether voluntary or involuntary, the Holders
of shares of Class B Preferred then outstanding shall be entitled to receive,

the shares of Class B Preferred upon liquidation, dissolution or winding up of
the Corporation, the amount of $.001 per share plus an amount equal to all
accrued but unpaid dividends on such shares to the date of final distribution.
 
     (b) Neither the sale, lease or exchange (for cash, shares of stock,
securities or other consideration) of all or substantially all the property and
assets of the Corporation, nor the merger or consolidation of the Corporation
into or with any other corporation, or the merger or consolidation of any other
corporation into or with the Corporation, shall be deemed to be a dissolution,
liquidation or winding up, voluntary or involuntary, for the purposes of this
paragraph.

     (c) After payment to the Holders of the full preferential amount provided
for in this paragraph 4 ($605.20), holders of shares of Class B Preferred in
their capacity as Holders shall have no right or claim to any of the remaining
assets of the Corporation.
 
     (d) If the assets of the Corporation available for distribution to the
Holders upon dissolution, liquidation or winding up of the Corporation, whether
voluntary or involuntary, shall be insufficient to pay in full all amounts to
which the Holders are entitled pursuant to clause (a) of this paragraph 3, and
to which holders of any other class or series of stock of the Corporation
ranking on a parity with the Class B Preferred as to distribution upon
dissolution, liquidation or winding up of the Corporation (collectively, the
"Parity Stockholders") are entitled pursuant to the Certificate of
Incorporation, as it may be amended from time to time (including any Certificate
of Designations), then such assets shall be distributed among the Holders of the
Class B Preferred and the Parity Stockholders ratably in proportion to the full
amounts otherwise due such Holders and Parity Stockholders.
 
     4. Voting Rights.  (a) The Holders of shares of Class B Preferred shall

securities or other consideration) of all or substantially all the property and
assets of the Corporation, nor the merger or consolidation of the Corporation
into or with any other corporation, or the merger or consolidation of any other
corporation into or with the Corporation, shall be deemed to be a dissolution,
liquidation or winding up, voluntary or involuntary, for the purposes of this
paragraph.
 
     (c) After payment to the Holders of the full preferential amount provided
for in this paragraph 4 ($605.20), holders of shares of Class B Preferred in
their capacity as Holders shall have no right or claim to any of the remaining
assets of the Corporation.
 
     (d) If the assets of the Corporation available for distribution to the
Holders upon dissolution, liquidation or winding up of the Corporation, whether
voluntary or involuntary, shall be insufficient to pay in full all amounts to
which the Holders are entitled pursuant to clause (a) of this paragraph 3, and
to which holders of any other class or series of stock of the Corporation
ranking on a parity with the Class B Preferred as to distribution upon
dissolution, liquidation or winding up of the Corporation (collectively, the
"Parity Stockholders") are entitled pursuant to the Certificate of
Incorporation, as it may be amended from time to time (including any Certificate
of Designations), then such assets shall be distributed among the Holders of the
Class B Preferred and the Parity Stockholders ratably in proportion to the full
amounts otherwise due such Holders and Parity Stockholders.
 
     4. Voting Rights.  (a) The Holders of shares of Class B Preferred shall
vote together with the shares of Common Stock of the Corporation. The Holder of
each share of Class B Preferred shall be entitled to ten (10) votes per share of
Class B Preferred.
 
     (b) Voting rights hereunder shall be exercised at each meeting of
stockholders for the election of directors or otherwise or in connection with a
written consent in lieu thereof, as the case may be.
 
     B. Common Stock.  SUBJECT TO THE RIGHTS, PRIVILEGES, PREFERENCES AND
PRIORITIES OF ANY HOLDERS OF SERIAL PREFERRED STOCK, the Common Stock shall be
entitled to dividends out of funds legally available therefor, when, as and if
declared and paid to the holders of Common Stock, and upon liquidation,
dissolution or winding up of the Corporation, to share ratably in the assets of
the Corporation available for distribution to the holders of Common Stock.
Except as otherwise provided herein or by law, the holders of the Common Stock
shall have full voting rights and powers, and each share of Common Stock shall
be entitled to one vote. All shares of Common Stock shall be identical with each
other in every respect. [If Proposal 3 is not approved, to read: "C. Common
Stock. Subject to the rights, privileges, preferences and priorities of any
holders of Class A Convertible Preferred Stock and any Serial Preferred Stock,
the Common Stock shall be entitled to dividends out of funds legally available

in the assets of the Corporation available for distribution to the holders of
Common Stock. Except as otherwise provided herein or by law, the holders of the
Common Stock shall have full voting rights and powers, and each share of Common
Stock shall be entitled to one vote. All shares of Common Stock shall be
identical with each other in every respect.]

                            ALLEGRO NEW MEDIA, INC.
 
                         1994 LONG-TERM INCENTIVE PLAN
 
     1. PURPOSE.  The purpose of the 1994 Long-Term Incentive Plan (the "Plan")
is to advance the interests of Allegro New Media, Inc., a Delaware corporation
(the "Company"), and its shareholders by providing incentives to certain key
employees of the Company and its affiliates and to certain other key individuals
who perform services for these entities, including those who contribute
significantly to the strategic and long-term performance objectives and growth
of the Company and its affiliates.
 
     2. ADMINISTRATION.
 
     (a) The Plan shall be determined solely by the Long-Term Incentive Plan
Administrative Committee (the "Committee") of the Board of Directors (the
"Board") of the Company, as such Committee is from time to time constituted, or
any successor committee the Board may designate to administer the Plan; provided
that if at any time Rule 16b-3 or any successor rule ("Rule 16b-3") under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), so permits
without adversely affecting the ability of the Plan to comply with the
conditions for exemption from Section 16 of the Exchange Act (or any successor
provision) provided by Rule 16b-3, the Committee may delegate the administration
of the Plan in whole or in part, on such terms and conditions, and to such
person or persons as it may determine in its discretion, as it relates to
persons not subject to Section 16 of the Exchange Act (or any successor
provision). The membership of the Committee or such successor committee shall be
constituted so as to comply at all times with the applicable requirements of
Rule 16b-3. No member of the Committee shall be eligible or have been eligible
within one year prior to his appointment to receive awards under the Plan
("Awards") or to receive awards under any other plan, program or arrangement of
the Company or any of its affiliates if such eligibility would cause such member
to cease to qualify AS A "NON-EMPLOYEE DIRECTOR" OR ANY SUCCESSOR STANDARD under
Rule 16b-3 AS THEN IN EFFECT; provided that if at any time Rule 16b-3 so permits
without adversely affecting the ability of the Plan to comply with the
conditions for exemption from Section 16 of the Exchange Act (or any successor
provision) provided by Rule 16b-3, one or more members of the Committee may
cease to QUALIFY AS A "NON-EMPLOYEE DIRECTOR" OR ANY SUCCESSOR STANDARD.
 
     (b) The Committee has all the powers vested in it by the terms of the Plan
set forth herein, such powers to include exclusive authority (except as may be
delegated as permitted herein) to select the key employees and other key
individuals to be granted Awards under the Plan, to determine the type, size and
terms of the Award to be made to each individual selected, to modify the terms
of any Award that has been granted, to determine the time when awards will be
granted, to establish performance objectives, to make any adjustments necessary
or desirable as a result of the granting of Awards to eligible individuals
located outside the United States and to prescribe the form of the instruments
embodying Awards made under the Plan. The Committee is authorized to interpret
the Plan and the Awards granted under the Plan, to establish, amend and rescind
any rules and regulations relating to the Plan, and to make any other
determination, which it deems necessary or desirable for the administration of
the Plan. The Committee (or its delegate as permitted herein) may correct any
defect or supply any omission or reconcile any inconsistency in the Plan or in
any Award in the manner and to the extent the Committee deems necessary or
desirable to carry it into effect. Any decision of the Committee (or its
delegate as permitted herein) in the interpretation and administration of the
Plan, as described herein, shall lie within its sole and absolute discretion and
shall be final, conclusive and binding on all parties concerned. The Committee
may act only by a majority of its members in office, except that the members
thereof may authorize any one or more of their members or any officer of the
Company to execute and deliver documents or to take any other ministerial action
on behalf of the Committee with respect to Awards made or to be made to Plan
participants. No member of the Committee and no officer of the Company shall be
liable for anything done or omitted to be done by him, by any other member of
the Committee or by any officer of the Company in connection with the
performance of duties under the Plan, except for his own willful misconduct or
as expressly provided by statute. Determinations to be made by the Committee
under the Plan may be made by its delegates.

     3. PARTICIPATION.
 
     (a) Affiliates.  If an Affiliate (as hereinafter defined) of the Company
wishes to participate in the Plan and its participation shall have been approved
by the Board upon the recommendation of the Committee, the board of directors or
other governing body of the Affiliate shall adopt a resolution in form and
substance satisfactory to the Committee authorizing participation by the
Affiliate in the Plan with respect to its key employees or other key individuals
performing services for it. As used herein, the term "Affiliate" means any
entity in which the Company has a substantial direct or indirect equity interest
or which has a substantial direct or indirect equity interest in the Company, as
determined by the Committee in its discretion.
 
     An Affiliate participating in the Plan may cease to be a participating
company at any time by action of the Board or by action of the board of
directors or other governing body of such Affiliate, which latter action shall
be effective not earlier than the date of delivery to the Secretary of the
Company of a certified copy of a resolution of the Affiliate's board of
directors or other governing body taking such action. If the participation in
the Plan of an Affiliate shall terminate, such termination shall not relieve it
of any obligations theretofore incurred by it, except as may be approved by the
Committee in its discretion.
 
     (b) Participants.  Consistent with the purposes of the Plan, the Committee
shall have exclusive power (except as may be delegated as permitted herein) to
select the key employees and other key individuals performing services for the
Company, including consultants or independent contractors and others who perform
services for the Company and its Affiliates who may participate in the Plan and
be granted Awards under the Plan. Eligible individuals may be selected
individually or by groups or categories, as determined by the Committee in its
discretion. No director of the Company, unless he is an employee of the Company
or is an officer or director of an Affiliate, shall be eligible to receive an
Award under the Plan. In no event may a corporation be eligible to receive an
Award under the Plan.
 
     4. AWARDS UNDER THE PLAN.
 
     (a) Types of Awards.  Awards under the Plan may include, but need not be
limited to, one or more of the following types, either alone or in any
combination thereof: (i) "Stock Options," (ii) "Stock Appreciation Rights,"
(iii) "Restricted Stock," (iv) "Performance Grants" and (v) any other type of
Award deemed by the Committee in its discretion to be consistent with the
purposes of the Plan (including but not limited to, Awards of or options or
similar rights granted with respect to unbundled stock units or components
thereof, and Awards to be made to participants who are foreign nationals or are
employed or performing services outside the United States). Stock Options, which
include "Non-Qualified Stock Options" and "Incentive Stock Options" or
combinations thereof, are rights to purchase common shares of the Company and
stock of any other class into which such shares may thereafter be changed (the
"Common Shares"). Non-Qualified Stock Options and Incentive Stock Options are
subject to the terms, conditions and restrictions specified in Paragraph 5.
Stock Appreciation Rights are rights to receive (without payment to the Company)
cash, Common Shares, other Company securities (which may include, but need not
be limited to, unbundled stock units or components thereof, debentures,
preferred stock, warrants, securities convertible into Common Shares or other
property, and other types of securities including, but not limited to, those of
the Company or an Affiliate, or any combination thereof ("Other Company
Securities") or property, or other forms of payment, or any combination thereof,
as determined by the Committee, based on the increase in the value of the number
of Common Shares specified in the Stock Appreciation Rights. Stock Appreciation
Rights are subject to the terms, conditions and restrictions specified in
Paragraph 6. Shares of Restricted Stock are Common Shares which are issued
subject to certain restrictions pursuant to Paragraph 7. Performance Grants are
contingent awards subject to the terms, conditions and restrictions described in
Paragraph 8, pursuant to which the participant may become entitled to receive
cash, Common Shares, Other Company Securities or property, or other forms of
payment, or any combination thereof, as determined by the Committee.
 
     (b) Maximum Number of Shares that May Be Issued.  There may be issued under
the Plan (as Restricted Stock, in payment of Performance Grants, pursuant to the
exercise of Stock Options or Stock Appreciation Rights, or in payment of or
pursuant to the exercise of such other Awards as the Committee, in its
discretion, may determine) an aggregate of not more than 3,000,000 Common
Shares, subject to adjustment as provided in Paragraph 15. Common Shares issued
pursuant to the Plan may be either
 
                                       G-2
<PAGE>   247
 
authorized but unissued shares, treasury shares, reacquired shares, or any
combination thereof. If any Common Shares issued as Restricted Stock or
otherwise subject to repurchase or forfeiture rights are reacquired by the
Company pursuant to such rights, or if any Award is cancelled, terminates or
expires unexercised, any Common Shares that would otherwise have been issuable
pursuant thereto will be available for issuance under new Awards.
 
     (c) Rights with Respect to Common Shares and Other Securities.
 
     (i) Unless otherwise determined by the Committee in its discretion, a
participant to whom an Award of Restricted Stock has been made (and any person
succeeding to such a participant's rights pursuant to the Plan) shall have,
after issuance of a certificate or copy thereof for the number of Common Shares
awarded and prior to the expiration of the Restricted Period or the earlier
repurchase of such Common Shares as herein provided, ownership of such Common
Shares, including the right to vote the same and to receive dividends or other
distributions made or paid with respect to such Common Shares (provided that
such Common Shares, and any new, additional or different shares, or Other
Company Securities or property, or other forms of consideration which the
participant may be entitled to receive with respect to such Common Shares as a
result of a stock split, stock dividend or any other change in the corporate or
capital structure of the Company, shall be subject to the restrictions
hereinafter described as determined by the Committee in its discretion),
subject, however, to the options, restrictions and limitations imposed thereon
pursuant to the Plan. Notwithstanding the foregoing, unless otherwise determined
by the Committee in its discretion, a participant with whom an Award agreement
is made to issue Common Shares in the future shall have no rights as a
shareholder with respect to Common Shares related to such agreement until
issuance of a certificate to him.
 
     (ii) Unless otherwise determined by the Committee in its discretion, a
participant to whom a grant of Stock Options, Stock Appreciation Rights,
Performance Grants or any other Award is made (and any person succeeding to such
a participant's rights pursuant to the Plan) shall have no rights as a
stockholder with respect to any Common Shares or as a holder with respect to
other securities, if any, issuable pursuant to any such Award until the date of
the issuance of a stock certificate to him for such Common Shares or other
instrument of ownership, if any. Except as provided in Paragraph 15, no
adjustment shall be made for dividends, distributions or other rights (whether
ordinary or extraordinary, and whether in cash, securities, other property or
other forms of consideration, or any combination thereof) for which the record
date is prior to the date such stock certificate or other instrument of
ownership, if any, is issued.
 
     5. STOCK OPTIONS.  The Committee may grant Stock Options either alone, or
in conjunction with Stock Appreciation Rights, Performance Grants or other
Awards, either at the time of grant or by amendment thereafter, provided that an
Incentive Stock Option may be granted only to an eligible employee of the
Company or its parent or subsidiary corporation. Each Stock Option (referred to
herein as an "Option") granted under the Plan shall be evidenced by an
instrument in such form as the Committee shall prescribe from time to time in
accordance with the Plan and shall comply with the following terms and
conditions, and with such other terms and conditions, including, but not limited
to, restrictions upon the Option or the Common Shares issuable upon exercise
thereof, as the Committee, in its discretion, shall establish:
 
     (a) The option price may be less than, equal to, or greater than, the fair
market value of the Common Shares subject to such Option at the time the Option
is granted, as determined by the Committee, but in no event will such option
price be less than 85% of the fair market value of the underlying Common Shares
at the time the Option is granted; provided, however, that in the case of an
Incentive Stock Option granted to such an employee, the option price shall not
be less than the fair market value of the Common Shares subject to such Option
at the time the Option is granted, or if granted to such an employee who owns
stock representing more than ten percent of the voting power of all classes of
stock of the Company or of its parent or subsidiary (a "Ten Percent Employee"),
such option price shall be not less than 110% of such fair market value at the
time the Option is granted; provided, further that in no event will such option
price be less than the par value of such Common Shares.
 
     (b) The Committee shall determine the number of Common Shares to be subject
to each option. The number of Common Shares subject to an outstanding Option may
be reduced on a share-for-share or other appropriate basis, as determined by the
Committee, to the extent that Common Shares under such Option are
 
                                       G-3
<PAGE>   248
 
used to calculate the cash, Common Shares, Other Company Securities or property,
or other forms of payment, or any combination thereof, received pursuant to
exercise of a Stock Appreciation Right attached to such Option, or to the extent
that any other Award granted in conjunction with such Option is paid.
 
     (c) The Option may not be sold, assigned, transferred, pledged,
hypothecated or otherwise disposed of, except by will or the laws of descent and
distribution, and shall be exercisable during the grantee's lifetime only by
him. Unless the Committee determines otherwise, the Option shall not be
exercisable for at least six months after the date of grant, unless the grantee
ceases employment or performance of services before the expiration of such
six-month period by reason of his disability as defined in Paragraph 12 or his
death.
 
     (d) The Option shall not be exercisable:
 
          (i) in the case of any Incentive Stock Option granted to a Ten Percent
     Employee, until after the expiration of five years from the date it is
     granted, and, in the case of any other Option, until after the expiration
     of ten years from the date it is granted. Any Option may be exercised
     during such period only at such time or times and in such installments as
     the Committee may establish;
 
          (ii) unless payment in full is made for the shares being acquired
     thereunder at the time of exercise, such payment shall be made in such form
     (including, but not limited to, cash, Common Shares, or the surrender of
     another outstanding Award under the Plan, or any combination thereof) as
     the Committee may determine in its discretion; and
 
          (iii) unless the person exercising the Option has been, at all times
     during the period beginning with the date of the grant of the Option and
     ending on the date of such exercise, employed by or otherwise performing
     services for the Company or an Affiliate, or a corporation, or a parent or
     subsidiary of a corporation, substituting or assuming the Option in a
     transaction to which Section 425(a) of the Internal Revenue Code of 1986,
     as amended, or any successor statutory provisions thereto (the "Code"), is
     applicable, except that:
 
             (A) in the case of any Non-Qualified Stock Option, if such person
        shall cease to be employed by or otherwise performing services for the
        Company or an Affiliate solely by reason of a period of Related
        Employment as defined in Paragraph 14, he may, during such period of
        Related Employment, exercise the Non-Qualified Stock Option as if he
        continued such employment or performance of service; or
 
             (B) if such person shall cease such employment or performance of
        services by reason of his disability as defined in Paragraph 12 or
        early, normal or deferred retirement under an approved retirement
        program of the Company or an Affiliate (or such other plan or
        arrangement as may be approved by the Committee, in its discretion, for
        this purpose) while holding an option which has not expired and has not
        been fully exercised, such person, at any time within three years (or
        such other period determined by the Committee) after the date he ceased
        such employment or performance of services (but in no event after the
        Option has expired), may exercise the Option with respect to any shares
        as to which he could have exercised the Option on the date he ceased
        such employment or performance of services, or with respect to such
        greater number of shares as determined by the Committee; or
 
             (C) if such person shall cease such employment or performance of
        services for reasons other than Related Employment, disability, early,
        normal or deferred retirement or death (as provided elsewhere) while
        holding an Option which has not expired and has not been fully
        exercised, such person may exercise the Option at any time during the
        period, if any, which the Committee approves (but not beyond the
        expiration of the Option) following the date he ceased such employment
        or performance of services with respect to any shares as to which he
        could have exercised the Option on the date he ceased such employment or
        performance of services or, in the Committee's discretion, any or all
        shares under the Option whether or not he could have exercised the
        Option on the date he ceased such employment or performance of services;
        or
 
                                       G-4
<PAGE>   249
 
             (D) if any person to whom an Option has been granted shall die
        holding an Option which has not expired and has not been fully
        exercised, his executors, administrators, heirs or distributees, as the
        case may be, may, at any time within one year (or such other period
        determined by the Committee) after the date of death (but in no event
        after the Option has expired), exercise the Option with respect to any
        shares as to which the decedent could have exercised the Option at the
        time of his death, or with respect to such greater number of shares as
        determined by the Committee.
 
     (e) In the case of an Incentive Stock Option, the amount of aggregate fair
market value of Common Shares (determined at the time of grant of the Option
pursuant to subparagraph 5(a) of the Plan) with respect to which incentive stock
options are exercisable for the first time by an employee during any calendar
year (under all such plans of his employer corporation and its parent and its
parent and subsidiary corporations) shall not exceed $100,000.
 
     (f) It is the intent of the Company that Non-Qualified Stock Options
granted under the Plan not be classified as Incentive Stock Options, that the
Incentive Stock Options granted under the Plan be consistent with and contain or
be deemed to contain all provisions required under Section 422A and other
appropriate provisions of the Code and any implementing regulations (and any
successor provisions thereof), and that any ambiguities in construction shall be
interpreted in order to effectuate such intent. The Agreements providing
Non-Qualified Stock Options shall provide that such Options are not "incentive
stock options" for the purposes of Section 422A of the Code.
 
     6. STOCK APPRECIATION RIGHTS.  The Committee may grant Stock Appreciation
Rights either alone, or in conjunction with Stock Options, Performance Grants or
other Awards, either at the time of grant or by amendment thereafter. Each Award
of Stock Appreciation Rights granted under the Plan shall be evidenced by an
instrument in such form as the Committee shall prescribe from time to time in
accordance with the Plan and shall comply with the following terms and
conditions, and with such other terms and conditions, including, but not limited
to, restrictions upon the Award of Stock Appreciation Rights or the Common
Shares issuable upon exercise thereof, as the Committee in its discretion shall
establish:
 
     (a) The Committee shall determine the number of Common Shares to be subject
to each Award of Stock Appreciation Rights. The number of Common Shares subject
to an outstanding Award of Stock Appreciation Rights may be reduced on a
share-for-share or other appropriate basis, as determined by the Committee, to
the extent that Common Shares under such Award of Stock Appreciation Rights are
used to calculate the cash, Common Shares, Other Company Securities or property,
or other forms of payment, or any combination thereof, received pursuant to
exercise of an Option attached to such Award of Stock Appreciation Rights, or to
the extent that any other Award granted in conjunction with such Award of Stock
Appreciation Rights is paid.
 
     (b) The Award of Stock Appreciation Rights may not be sold, assigned,
transferred, pledged, hypothecated or otherwise disposed of, except by will or
the laws of the descent and distribution, and shall be exercisable during the
grantee's lifetime only by him. Unless the Committee determines otherwise, the
Award of Stock Appreciation Rights shall not be exercisable for at least six
months after the date of grant, unless the grantee ceases employment or
performance of services before the expiration of such six-month period by reason
of his disability as defined in Paragraph 12 or his death.
 
     (c) The Award of Stock Appreciation Rights shall not be exercisable:
 
          (i) in the case of any Award of Stock Appreciation Rights that are
     attached to an Incentive Stock Option granted to a Ten Percent Employee,
     after the expiration of five years from the date it is granted, and, in the
     case of any other award of Stock Appreciation Rights, after the expiration
     of ten years from the date it is granted. Any Award of Stock Appreciation
     Rights may be exercised during such period only at such time or times and
     in such installments as the Committee may establish;
 
          (ii) unless the Option or other Award to which the Award of Stock
     Appreciation Rights is attached is at the time exercisable; and
 
                                       G-5
<PAGE>   250
 
          (iii) unless the person exercising the Award of Stock Appreciation
     Rights has been, at all times during the period beginning with the date of
     the grant thereof and ending on the date of such exercise, employed by or
     otherwise performing services for the Company or an Affiliate, except that
 
             (A) in the case of any Award of Stock Appreciation Rights (other
        than those attached to an Incentive Stock Option), if such person shall
        cease to be employed by or otherwise performing services for the Company
        or an Affiliate solely by reason of a period of Related Employment as
        defined in Paragraph 14, he may, during such period of Related
        Employment, exercise the Award of Stock Appreciation Rights as if he
        continued such employment or performance of services; or
 
             (B) if such person shall cease such employment or performance of
        services by reason of his disability as defined in Paragraph 12 or
        early, normal or deferred retirement under an approved retirement
        program of the Company or an Affiliate (or such other plan or
        arrangement as may be approved by the Committee, in its discretion, for
        this purpose) while holding an Award of Stock Appreciation Rights which
        has not expired and has not been fully exercised, such person may, at
        any time within three years (or such other period determined by the
        Committee) after the date he ceased such employment or performance of
        services (but in no event after the Award of Stock Appreciation Rights
        has expired), exercise the Award of Stock Appreciation Rights with
        respect to any shares as to which he could have exercised the Award of
        Stock Appreciation Rights on the date he ceased such employment or
        performance of services, or with respect to such greater number of
        shares as determined by the Committee; or
 
             (C) if such person shall cease such employment or performance of
        services for reasons other than Related Employment, disability, early,
        normal or deferred retirement or death (as provided elsewhere) while
        holding an Award of Stock Appreciation Rights which has not expired and
        has not been fully exercised, such person may exercise the Award of
        Stock Appreciation Rights at any time during the period, if any, which
        the Committee approves (but in no event after the Award of Stock
        Appreciation Rights expires) following the date he ceased such
        employment or performance of services with respect to any shares as to
        which he could have exercised the Award of Stock Appreciation Rights on
        the date he ceased such employment or performance of services or as
        otherwise permitted in the Committee's discretion; or
 
             (D) if any person to whom an Award of Stock Appreciation Rights has
        been granted shall die holding an Award of Stock Appreciation Rights
        which has not expired and has not been fully exercised, his executors,
        administrators, heirs or distributees, as the case may be, may, at any
        time within one year (or such other period determined by the Committee)
        after the date of death (but in no event after the Award of Stock
        Appreciation Rights has expired), exercise the Award of Stock
        Appreciation Rights with respect to any shares as to which the decedent
        could have exercised the Award of Stock Appreciation Rights at the time
        of his death, or with respect to such greater number of shares as
        determined by the Committee.
 
     (d) An Award of Stock Appreciation Rights shall entitle the holder (or any
person entitled to act under the provisions of subparagraph 6(c)(iii)(D) hereof)
to exercise such Award or to surrender unexercised the option (or other Award)
to which the Stock Appreciation Rights is attached (or any portion of such
Option or other Award) to the Company and to receive from the Company in
exchange therefor, without payment to the Company, that number of Common Shares
having an aggregate value equal to the excess of the fair market value of one
share, at the time of such exercise, over the exercise price (or Option Price,
as the case may be) per share, times the number of shares subject to the Award
or the Option (or other Award), or portion thereof, which is so exercised or
surrendered, as the case may be. The Committee shall be entitled in its
discretion to elect to settle the obligation arising out of the exercise of a
Stock Appreciation Right by the payment of cash or Other Company Securities or
property, or other forms of payment, or any combination thereof, as determined
by the Committee, equal to the aggregate value of the Common Shares it would
otherwise be obligated to deliver. Any such election by the Committee shall be
made as soon as practicable after the receipt by the Committee of written notice
of the exercise of the Stock Appreciation Right. The value of a Common Share,
Other Company Securities or property, or other forms of payment determined by
 
                                       G-6
<PAGE>   251
 
the Committee for this purpose shall be the fair market value thereof on the
last business day next preceding the date of the election to exercise the Stock
Appreciation Right, unless the Committee, in its discretion, determines
otherwise.
 
     (e) A Stock Appreciation Right may provide that it shall be deemed to have
been exercised at the close of business on the business day preceding the
expiration date of the Stock Appreciation Right or of the related Option (or
other Award), or such other date as specified by the Committee, if at such time
such Stock Appreciation Right has a positive value. Such deemed exercise shall
be settled or paid in the same manner as a regular exercise thereof as provided
in subparagraph 6(d) hereof.
 
     (f) No fractional shares may be delivered under this Paragraph 6, but in
lieu thereof a cash or other adjustment shall be made as determined by the
Committee in its discretion.
 
     7. RESTRICTED STOCK.  Each Award of Restricted Stock under the Plan shall
be evidenced by an instrument in such form as the Committee shall prescribe from
time to time in accordance with the Plan and shall comply with the following
terms and conditions, and with such other terms and conditions as the Committee,
in its discretion, shall establish:
 
     (a) The Committee shall determine the number of Common Shares to be issued
to a participant pursuant to the Award, and the extent, if any, to which they
shall be issued in exchange for cash, other consideration, or both.
 
     (b) Common Shares issued to a participant in accordance with the Award may
not be sold, assigned, transferred, pledged, hypothecated or otherwise disposed
of, except by will or the laws of descent and distribution, or as otherwise
determined by the Committee, for such period as the Committee shall determine,
from the date on which the Award is granted (the "Restricted Period"). The
Company will have the option, at the Committee's discretion, to repurchase the
shares subject to the Award at such price as the Committee shall have fixed or
to provide for forfeiture to the Company of the shares subject to the Award,
which option or forfeiture may be exercisable (i) if the participant's
continuous employment or performance of services for the Company and its
Affiliates shall terminate for any reason, except solely by reason of a period
of Related Employment as defined in Paragraph 14, or except as otherwise
provided in subparagraph 7(c), prior to the expiration of the Restricted Period,
(ii) if, on or prior to the expiration of the Restricted Period or the earlier
lapse of such forfeiture option, the participant has not paid to the Company an
amount equal to any federal, state, local or foreign income or other taxes which
the Company determines is required to be withheld in respect of such shares, or
(iii) under such other circumstances as determined by the Committee in its
discretion. Such repurchase option or forfeiture shall be exercisable on such
terms, in such manner and during such period as shall be determined by the
Committee when the Award is made or as amended thereafter, except as otherwise
determined in the Committee's discretion. Each certificate for Common Shares
issued pursuant to a Restricted Stock Award shall bear an appropriate legend
referring to the foregoing repurchase option or forfeiture and other
restrictions and to the fact that the shares are partly paid, shall be deposited
by the award holder with the Company, together with a stock power endorsed in
blank, or shall be evidenced in such other manner permitted by applicable law as
determined by the Committee in its discretion. Any attempt to dispose of any
such Common Shares in contravention of the foregoing repurchase and forfeiture
options and other restrictions shall be null and void and without effect. If
Common Shares issued pursuant to a Restricted Stock Award shall be repurchased
or forfeited pursuant to the repurchase option described above, the participant,
or in the event of his death, his personal representative, shall forthwith
deliver to the Secretary of the Company the certificates for the Common Shares
awarded to the participant, accompanied by such instrument of transfer, if any,
as may reasonably be required by the Secretary of the Company.
 
     (c) If a participant who has been in continuous employment or performance
of services for the Company or an Affiliate since the date on which a Restricted
Stock Award was granted to him shall, while in such employment or performance of
services, die, or terminate such employment or performance of services by reason
of disability as defined in Paragraph 12 or by reason of early normal or
deferred retirement under an approved retirement program of the Company or an
Affiliate (or such other plan or arrangement as may be approved by the Committee
in its discretion, for this purpose) and any of such events shall occur after
the date on which the Award was granted to him and prior to the end of the
Restricted Period of such Award, the
 
                                       G-7
<PAGE>   252
 
Committee may determine to cancel the repurchase option or forfeiture (and any
and all other restrictions) on any or all of the Common Shares subject to such
Award; and the repurchase option or forfeiture shall become exercisable at such
time as to the remaining shares, if any.
 
     8. PERFORMANCE GRANTS.  The Award of a Performance Grant ("Performance
Grant") to a participant will entitle him to receive a specified amount
determined by the Committee (the "Actual Value"), if the terms and conditions
specified herein and in the Award are satisfied. Each Award of a Performance
Grant shall be subject to the following terms and conditions, and to such other
terms and conditions, including but not limited to, restrictions upon any cash,
Common Shares, Other Company Securities or property, or other forms of payment,
or any combination thereof, issued in respect of the Performance Grant, as the
Committee, in its discretion, shall establish, and shall be embodied in an
instrument in such form and substance as is determined by the Committee.
 
     (a) The Committee shall determine the value or range of values of a
Performance Grant to be awarded to each participant selected for an award and
whether or not such a Performance Grant is granted in conjunction with an Award
of Options, Stock Appreciation Rights, Restricted Stock or other Award, or any
combination thereof, under the Plan (which may include, but need not be limited
to, deferred Awards) concurrently or subsequently granted to the participant
(the "Associated Award"). As determined by the Committee, the maximum value of
each Performance Grant (the "Maximum Value") shall be: (i) an amount fixed by
the Committee at the time the award is made or amended thereafter, (ii) an
amount which varies from time to time based in whole or in part on the then
current value of a Common Share, Other Company Securities or property, or other
securities or property, or any combination thereof, or (iii) an amount that is
determinable from criteria specified by the Committee. Performance Grants may be
issued in different classes or series having different names, terms and
conditions. In the case of a Performance Grant awarded in conjunction with an
Associated Award, the Performance Grant may be reduced on an appropriate basis
to the extent that the Associated Award has been exercised, paid to or otherwise
received by the participant, as determined by the Committee.
 
     (b) The award period ("Award Period") in respect of any Performance Grant
shall be a period determined by the Committee. At the time each Award is made,
the Committee shall establish performance objectives to be attained within the
Award Period as the means of determining the Actual Value of such a Performance
Grant. The performance objectives shall be based on such measure or measures of
performance, which may include, but need not be limited to, the performance of
the participant, the Company, one or more of its subsidiaries or one or more of
their divisions or units, or any combination of the foregoing, as the Committee
shall determine, and may be applied on an absolute basis or be relative to
industry or other indices, or any combination thereof. The Actual Value of a
Performance Grant shall be equal to its Maximum Value only if the performance
objectives are attained in full, but the Committee shall specify the manner in
which the Actual Value of Performance Grants shall be determined if the
performance objectives are met in part. Such performance measures, the Actual
Value or the Maximum Value, or any combination thereof, may be adjusted in any
manner by the Committee in its discretion at any time and from time to time
during or as soon as practicable after the Award Period, if it determines that
such performance measures, the Actual Value or the Maximum Value, or any
combination thereof, are not appropriate under the circumstances.
 
     (c) The rights of a participant in Performance Grants awarded to him shall
be provisional and may be cancelled or paid in whole or in part, all as
determined by the Committee, if the participant's continuous employment or
performance of services for the Company and its Affiliates shall terminate for
any reason prior to the end of the Award Period, except solely by reason of a
period of Related Employment as defined in Paragraph 14.
 
     (d) The Committee shall determine whether the conditions of subparagraph
8(b) or 8(c) hereof have been met and, if so, shall ascertain the Actual Value
of the Performance Grants. If the Performance Grants have no Actual Value, the
Award and such Performance Grants shall be deemed to have been cancelled and
 
                                       G-8
<PAGE>   253
 
the Associated Award, if any, may be cancelled or permitted to continue in
effect in accordance with its terms. If the Performance Grants have any Actual
Value and:
 
          (i) were not awarded in conjunction with an Associated Award, the
     Committee shall cause an amount equal to the actual Value of the
     Performance Grants earned by the participant to be paid to him or his
     beneficiary as provided below; or
 
          (ii) were awarded in conjunction with an Associated Award, the
     Committee shall determine, in accordance with criteria specified by the
     Committee (A) to cancel the Performance Grants, in which event no amount in
     respect thereof shall be paid to the participant or his beneficiary, and
     the Associated Award may be permitted to continue in effect in accordance
     with its terms, (B) to pay the Actual Value of the Performance Grants to
     the participant or his beneficiary as provided below, in which event the
     Associated Award may be cancelled or (C) to pay to the participant or his
     beneficiary as provided below, the Actual Value of only a portion of the
     Performance Grants, in which a complimentary portion of the Associated
     Award may be permitted to continue in effect in accordance with its terms
     or be cancelled, as determined by the Committee.
 
     Such determination by the Committee shall be made as promptly as
practicable following the end of the Award Period or upon the earlier
termination of employment or performance of services, or at such other time or
times as the Committee shall determine, and shall be made pursuant to criteria
specified by the Committee.
 
     Payment of any amount in respect of the Performance Grants which the
Committee determines to pay as provided above shall be made by the Company as
promptly as practicable after the end of the Award Period or at such other time
or times as the Committee shall determine, and may be made in cash, Common
Shares, Other Company Securities or property, or other forms of payment, or any
combination thereof or in such other manner, as determined by the Committee in
its discretion. Notwithstanding anything in this Paragraph 8 to the contrary,
the Committee may, in its discretion, determine and pay out the Actual Value of
the Performance Grants at any time during the Award Period.
 
     9. DEFERRAL OF COMPENSATION.  The Committee shall determine whether or not
an Award shall be made in conjunction with deferral of the participant's salary,
bonus or other compensation, or any combination thereof, and whether or not such
deferred amounts may be
 
          (i) forfeited to the Company or to other participants, or any
     combination thereof, under certain circumstances (which may include, but
     need not be limited to, certain types of termination of employment or
     performance of services for the Company and its Affiliates),
 
          (ii) subject to increase or decrease in value based upon the
     attainment of or failure to attain, respectively, certain performance
     measures and/or
 
          (iii) credited with income equivalents (which may include, but need
     not be limited to, interest, dividends or other rates of return) until the
     date or dates of payment of the Award, if any.
 
     10. DEFERRED PAYMENT OF AWARDS.  The Committee may specify that the payment
of all or any portion of cash, Common Shares, Other Company Securities or
property, or any other form of payment, or any combination thereof, under an
Award shall be deferred until a later date. Deferrals shall be for such periods
or until the occurrence of such events, and upon such terms, as the Committee
shall determine in its discretion. Deferred payments of Awards may be made by
undertaking to make payment in the future based upon the performance of certain
investment equivalents (which may include, but need not be limited to,
government securities, Common Shares, other securities, property or
consideration, or any combination thereof), together with such additional
amounts of income equivalents (which may be compounded and may include, but need
not be limited to, interest, dividends or other rates of return, or any
combination thereof) as may accrue thereon until the date or dates of payment,
such investment equivalents and such additional amounts of income equivalents to
be determined by the Committee in its discretion.
 
     11. AMENDMENT OR SUBSTITUTION OF AWARDS UNDER THE PLAN.  The terms of any
outstanding Award under the Plan may be amended from time to time by the
Committee in its discretion in any manner that it deems appropriate (including,
but not limited to, acceleration of the date of exercise of any
 
                                       G-9
<PAGE>   254
 
Award and/or payments thereunder, or reduction of the Option Price of an Option
or exercise price of an Award of Stock Appreciation Rights); provided, that no
such amendment shall adversely affect in a material manner any right of a
participant under the Award without his written consent, unless the Committee
determines in its discretion that there have occurred or are about to occur
significant changes in the participant's position, duties or responsibilities,
or significant changes in economic, legislative, regulatory, tax, accounting or
cost/benefit conditions which are determined by the Committee in its discretion
to have or to be expected to have a substantial effect on the performance of the
Company, or any subsidiary, affiliate, division or department thereof, on the
Plan or an any Award under the Plan. The Committee may, in its discretion,
permit holders of Awards to surrender outstanding Awards as a condition
precedent to the grant of new Awards under the Plan.
 
     12. DISABILITY.  For the purposes of this Plan, a participant shall be
deemed to have terminated his employment or performance of services for the
Company and its Affiliates by reason of disability if the Committee shall
determine that the physical or mental condition of the participant by reason of
which such employment or performance of services terminated was such at that
time as would entitle him to payment of monthly disability benefits under any
disability plan of the Company or an Affiliate in which he is a participant. If
the participant is not eligible for benefits under any disability plan of the
Company or an Affiliate, he shall be deemed to have terminated such employment
or performance of services by reason of disability if the Committee shall
determine that he is permanently and totally disabled within the meaning of
Section 22(e)(3) of the Code.
 
     13. TERMINATION OF A PARTICIPANT.  For all purposes under the Plan, the
Committee shall determine whether a participant has terminated employment by or
the performance of services for the Company or an Affiliate, provided that
transfers between the Company and an Affiliate or between Affiliates, and
approved leaves of absence shall not be deemed such a termination.
 
     14. RELATED EMPLOYMENT.  For the purposes of this Plan, Related Employment
shall mean the employment or performance of services by an individual for an
employer that is neither the Company nor an Affiliate, provided that (i) such
employment or performance of services is undertaken by the individual at the
request of the Company or an Affiliate, (ii) immediately prior to undertaking
such employment or performance of services, the individual was employed by or
performing services for the Company or an Affiliate or was engaged in Related
Employment as herein defined, and (iii) such employment or performance of
services is in the best interests of the Company and is recognized by the
Committee, in its discretion, as Related Employment for purposes of this
Paragraph 14. The death or disability of an individual during a period of
Related Employment as herein defined shall be treated, for purposes of this
Plan, as if the death or onset of disability had occurred while the individual
was employed by or performing services for the Company or an Affiliate.
 
     15. DILUTION AND OTHER ADJUSTMENTS.  In the event of any change in the
outstanding Common Shares of the Company by reason of any stock split, stock
dividend, split-up, split-off, spin-off, recapitalization, merger,
consolidation, rights offering, share offering, reorganization, combination or
exchange of shares, a sale by the Company of all or part of its assets, any
distribution to shareholders other than a normal cash dividend, or other
extraordinary or unusual event, if the Committee shall determine, in its
discretion, that such change equitably requires an adjustment in the terms of
any Award or the number of Common Shares available for Awards, such adjustment
may be made by the Committee and shall be final, conclusive and binding for all
purposes of the Plan.
 
     16. DESIGNATION OF BENEFICIARY BY PARTICIPANT.  A participant may name a
beneficiary to receive any payment to which he may be entitled in respect of any
Award under the Plan in the event of his death, on a written form to be provided
by and filed with the Committee, and in a manner determined by the Committee in
its discretion. The Committee reserves the right to review and approve
beneficiary designations. A participant may change his beneficiary from time to
time in the same manner, unless such participant has made an irrevocable
designation. Any designation of beneficiary under the Plan (to the extent it is
valid and enforceable under applicable law) shall be controlling over any other
disposition, testamentary or otherwise, as determined by the Committee in its
discretion. If no designated beneficiary survives the participant and is
 
                                      G-10
<PAGE>   255
 
living on the date on which any amount becomes payable to such participant's
beneficiary, such payment will be made to the legal representatives of the
participant's estate, and the term "beneficiary" as used in the Plan shall be
deemed to include such person or persons. If there is any question as to the
legal right of any beneficiary to receive a distribution under the Plan, the
Committee in its discretion may determine that the amount in question be paid to
the legal representatives of the estate of the participant, in which event the
Company, the Board and the Committee and the members thereof will have no
further liability to anyone with respect to such amount.
 
     17. CHANGE IN CONTROL.
 
     (a) Upon any Change in Control:
 
          (i) each Stock Option and Stock Appreciation Right that is outstanding
     on the date of such Change in Control shall be exercisable in full
     immediately;
 
          (ii) all restrictions with respect to Restricted Stock shall lapse
     immediately, and the Company's right to repurchase or forfeit any
     Restricted Stock outstanding on the date of such Change in Control shall
     thereupon terminate and the certificates representing such Restricted Stock
     and the related stock powers shall be promptly delivered to the
     participants entitled thereto; and
 
          (iii) All Award Periods for the purposes of determining the amounts of
     Awards of Performance Grants shall end as of the end of the calendar
     quarter immediately preceding the date of such Change in Control, and the
     amount of the Award payable shall be the portion of the maximum possible
     Award allocable to the portion of the Award Period that had elapsed and the
     results achieved during such portion of the Award Period.
 
     (b) For this purpose, a Change in Control shall be deemed to occur when and
only when any of the following events first occurs:
 
          (i) any person who is not currently such becomes the beneficial owner,
     directly or indirectly, of securities of the Company representing 25% or
     more of the combined voting power of the Company's then outstanding voting
     securities; or
 
          (ii) three or more directors, whose election or nomination for
     election is not approved by a majority of the Incumbent Board (as
     hereinafter defined), are elected within any single 24-month period to
     serve on the Board of Directors; or
 
          (iii) members of the Incumbent Board cease to constitute a majority of
     the Board of Directors without the approval of the remaining members of the
     Incumbent Board; or
 
          (iv) any merger (other than a merger where the Company is the survivor
     and there is no accompanying Change in Control under subparagraphs (i),
     (ii) or (iii) of this paragraph (b)), consolidation, liquidation or
     dissolution of the Company, or the sale of all or substantially all of the
     assets of the Company.
 
     Notwithstanding the foregoing, a Change in Control shall not be deemed to
occur pursuant to subparagraph (i) of this paragraph (b) solely because 25% or
more of the combined voting power of the Company's outstanding securities is
acquired by one or more employee benefit plans maintained by the Company or by
any other employer, the majority interest in which is held, directly or
indirectly, by the Company. For purposes of this Section 17, the terms "person"
and "beneficial owner" shall have the meaning set forth in Sections 3(a) and
13(d) of the Exchange Act, and in the regulations promulgated thereunder, as in
effect on December 15, 1993; and the term "Incumbent Board" shall mean (A) the
members of the Board of Directors of the Company on December 31, 1993, to the
extent that they continue to serve as members of the Board of Directors, and (B)
any individual who becomes a member of the Board of Directors after December 31,
1993, if his election or nomination for election as a director was approved by a
vote of at least three-quarters of the then Incumbent Board.

<PAGE>   256
 
     18. MISCELLANEOUS PROVISIONS.
 
     (a) No employee or other person shall have any claim or right to be granted
an Award under the Plan. Determinations made by the Committee under the Plan
need not be uniform and may be made selectively among eligible individuals under
the Plan, whether or not such eligible individuals are similarly situated.
Neither the Plan nor any action taken hereunder shall be construed as giving any
employee or other person any right to continue to be employed by or perform
services for the Company or any Affiliate, and the right to terminate the
employment of or performance of services by any participant at any time and for
any reason is specifically reserved.
 
     (b) No participant or other person shall have any right with respect to the
Plan, the Common Shares reserved for issuance under the Plan or in any Award,
contingent or otherwise, until written evidence of the Award shall have been
delivered to the recipient and all the terms, conditions and provisions of the
Plan and the Award applicable to such recipient (and each person claiming under
or through him) have been met.
 
     (c) Except as may be approved by the Committee where such approval shall
not adversely affect compliance of the Plan with Rule 16b-3 under the Exchange
Act, a participant's rights and interest under the Plan may not be assigned or
transferred, hypothecated or encumbered in whole or in part either directly or
by operation of law or otherwise (except in the event of a participant's death)
including, but not by way of limitation, execution, levy, garnishment,
attachment, pledge, bankruptcy or in any other manner; provided, however, that
any Option or similar right (including, but not limited to, a Stock Appreciation
Right) offered pursuant to the Plan shall not be transferable other than by will
or the laws of descent and distribution and shall be exercisable during the
participant's lifetime only by him.
 
     (d) No Common Shares, Other Company Securities or property, other
securities or property, or other forms of payment shall be issued hereunder with
respect to any Award unless counsel for the Company shall be satisfied that such
issuance will be in compliance with applicable federal, state, local and foreign
legal, securities exchange and other applicable requirements.
 
     (e) It is the intent of the Company that the Plan comply in all respects
with Rule 16b-3 under the Exchange Act, that any ambiguities or inconsistencies
in construction of the Plan be interpreted to give effect to such intention and
that if any provision of the Plan is found not to be in compliance with Rule
16b-3, such provision shall be deemed null and void to the extent required to
permit the Plan to comply with Rule 16b-3.
 
     (f) The Company and its Affiliates shall have the right to deduct from any
payment made under the Plan, any federal, state, local or foreign income or
other taxes required by law to be withheld with respect to such payment. It
shall be a condition to the obligation of the Company to issue Common Shares,
Other Company Securities or property, other securities or property, or other
forms of payment, or any combination thereof, upon exercise, settlement or
payment of any Award under the Plan, that the participant (or any beneficiary or
person entitled to act) pay to the Company, upon its demand, such amount as may
be requested by the Company for the purpose of satisfying any liability to
withhold federal, state, local or foreign income or other taxes. If the amount
requested is not paid, the Company may refuse to issue Common Shares, Other
Company Securities or property, other securities or property, or other forms of
payment, or any combination thereof. Notwithstanding anything in the Plan to the
contrary, the Committee may, in its discretion, permit an eligible participant
(or any beneficiary or person entitled to act) to elect to pay a portion or all
of the amount requested by the Company for such taxes with respect to such
Award, at such time and in such manner as the Committee shall deem to be
appropriate including, but not limited to, by authorizing the Company to
withhold, or agreeing to surrender to the Company on or about the date such tax
liability is determinable, Common Shares, Other Company Securities or property,
other securities or property, or other forms of payment, or any combination
thereof, owned by such person or a portion of such forms of payment that would
otherwise be distributed, or have been distributed, as the case may be, pursuant
to such Award to such person, having a fair market value equal to the amount of
such taxes.
 
                                      G-12
<PAGE>   257
 
     (g) The expenses of the Plan shall be borne by the Company. However, if an
Award is made to an individual employed by or performing services for an
Affiliate:
 
          (i) if such Award results in payment of cash to the participant, such
     Affiliate shall pay to the Company an amount equal to such cash payment
     unless the Committee shall otherwise determine in its discretion;
 
          (ii) if the Award results in the issuance by the Company to the
     participant of Common Shares, Other Company Securities or property, other
     securities or property, or other forms of payment, or any combination
     thereof, such Affiliate shall, unless the Committee shall otherwise
     determine in its discretion, pay to the Company an amount equal to the fair
     market value thereof, as determined by the Committee, on the date such
     Common Shares, other Company Securities or property, other securities or
     property, or other forms of payment, or any combination thereof, are issued
     (or in the case of the issuance of Restricted Stock or of Common Shares,
     Other Company Securities or property, or other securities or property, or
     other forms of payment subject to transfer and forfeiture conditions, equal
     to the fair market value thereof on the date on which they are no longer
     subject to applicable restrictions), minus the amount, if any, received by
     the Company in respect of the purchase of such Common Shares, Other Company
     Securities or property, other securities or property or other forms of
     payment, or any combination thereof, all as the Committee shall determine
     in its discretion; and
 
          (iii) the foregoing obligations of any such Affiliate entity shall
     survive and remain in effect and binding on such entity even if its status
     as an Affiliate of the Company should subsequently cease, except as
     otherwise agreed by the Company and the entity.
 
     (h) The Plan shall be unfunded. The Company shall not be required to
establish any special or separate fund or to make any other segregation of
assets to assure the payment of any Award under the Plan, and rights to the
payment of Awards shall be no greater than the rights of the Company's general
creditors.
 
     (i) By accepting any Award or other benefit under the Plan, each
participant and each person claiming under or through him shall be conclusively
deemed to have indicated his acceptance and ratification of, and consent to, any
action taken by the Company, the Board or the Committee or its delegates.
