ITEM 4.  THE SOLICITATION OR RECOMMENDATION

  (a) Recommendation of the Company Board

     At a meeting on October 6, 1999, the Company's board of directors (the
"Board") unanimously (i) determined that the Merger Agreement and the
transactions contemplated thereby, including the Offer and the Merger, are fair
to and in the best interests of the Company's stockholders; (ii) adopted and
approved the Merger Agreement and authorized the execution thereof by the
Company; and (iii) recommended that the Company's stockholders accept the Offer
and tender their Shares thereunder.

  (b) Background of and Reasons for the Board Recommendation

     In September, 1998, the Company's Board authorized the Company's chairman
to interview and select an investment banking firm to advise the board of
directors with regard to a potential sale of the Company. In December, 1998, the
Company's Board interviewed representatives from four investment banking firms,
including Advest, Inc. ("Advest").

     On January 4, 1999 the Company retained Advest, Inc. ("Advest") to act as
its exclusive financial advisor to pursue a potential sale of the Company.

     In January, 1999, James R. Riedman, as Chairman and Chief Executive Officer
of Daniel Green Company ("Daniel Green"), a manufacturer and distributor of
shoes whose stock is listed on the NASDAQ Small Cap Market, telephoned a
representative of the Company to extend condolences on the recent death of the
Company's chief executive officer and to indicate an interest in discussing a
possible combination of the Company and Daniel Green. Parent owns 35.1% of the
outstanding shares of Daniel Green and Mr. Riedman is President and Chief
Executive Officer of Parent.

     In January, 1999, during several conversations between representatives of
the Company and Advest, the parties discussed the viability of a sale of the
Company to a strategic or financial buyer, and the process

                                        2
<PAGE>   4

involved. After its discussion with the representatives of Advest, and taking
into account the continuing challenges facing the Company in the marketplace,
the Company's board of directors determined that it was in the best interest of
the stockholders of the Company to consider a sale of the Company.

     From February, 1999 to May, 1999, Advest contacted approximately 70
companies to explore whether they had any interest in acquiring the Company.
Only two of these calls resulted in expressions of interest.

     In March, 1999, a representative of Advest contacted Daniel Green and
provided it with a Confidentiality Agreement, which was signed on March 18,
1999, and Advest forwarded a Confidential Memorandum to Daniel Green.

     On March 24, 1999, a representative of Daniel Green telephoned a
representative of Advest to inquire about various aspects of the information
contained in the Confidential Memorandum.

     On March 30, 1999, a representative of Daniel Green wrote to a
representative of Advest expressing Daniel Green's strong interest in entering
into a merger with the Company or acquiring all of the Company's outstanding
Shares in a cash acquisition. Daniel Green indicated that it would be in a
position to support a value at a substantial premium to the Company's
then-current listed trading price of $8.50 per share, contingent on financing,
due diligence, negotiation of definitive agreements and approval of the
Company's Board.

     On April 16, 1999, a representative of Daniel Green wrote to a
representative of Advest expressing continued interest in acquiring the Company
and entering into discussions on specific terms, including paying a price of
$10.50 per share for a total consideration of $14,745,000.

     On April 23, 1999, representatives of Daniel Green met with representatives
of the Company, including members of management, and Advest at Advest's offices
in Boston, Massachusetts to discuss the Confidential Memorandum and other
information concerning both Daniel Green and the Company.

     On April 26, 1999, a representative of Daniel Green commenced due diligence
investigation of the Company with the materials assembled in the Advest data
room in Boston, Massachusetts.

     On April 29, 1999, Daniel Green wrote to a representative of Advest
outlining terms of a proposed acquisition of the Company to be structured as a
cash merger. Daniel Green proposed paying $14,745,000, or approximately $10.50
per share, contingent on financing, due diligence, negotiation of definitive
agreements and approval by the Company's Board. Accompanying the letter was a
letter from Daniel Green's bank proposing to finance the acquisition on terms
set forth therein.

     On April 30, 1999, Advest received a non-binding expression of interest
from another potential bidder indicating that it would be willing to pay a range
between $9.00 and $11.25 per share in an all-cash transaction.

     On May 5, 1999, a representative of Daniel Green telephoned a
representative of Advest to inquire about Daniel Green's proposal. The Advest
representative indicated that the Company was unwilling to engage in formal
negotiations at the $10.50 per share valuation of the Company proposed by Daniel
Green.

     Throughout May, 1999, the Company and Daniel Green continued to discuss a
possible merger.

     On May 26, 1999, Advest received a letter of intent from the other
potential bidder containing a proposed purchase price of $8.50 per share. After
consultation with its financial advisors, the Company instructed Advest not to
proceed because the proposed purchase price was determined not to be adequate.
After a period of one to two days, the potential bidder telephoned Advest and
informally indicated a willingness to pay a purchase price of $9.50 per share.
After consultation with Advest, the Company again instructed Advest not to
proceed because the proposed purchase price was determined not to be adequate.

     On June 7, 1999, a representative of Advest wrote to a representative of
Daniel Green setting out terms which would be acceptable to the Company, subject
to Board and stockholder approval, including aggregate consideration of
$15,798,250 in cash ($11.25 per share) plus 600,000 to 700,000 shares of Daniel
Green's common stock, registered and unrestricted.

                                        3
<PAGE>   5

     On June 8, 1999, a representative of Daniel Green telephoned a
representative of Advest and suggested a face-to-face meeting with the
principals of each company.

     On June 14, 1999, principals of Daniel Green and the Company met in
Rochester, New York and discussed a revised proposal wherein the consideration
would be $11.50 per share in cash, with an earn-out of $.50 per share if the
Company met certain performance criteria for the fiscal year ending November 30,
1999. Among the other terms discussed was a termination fee of $1.5 million and
a commitment by the Company not to solicit other bidders.

     On June 17, 1999, counsel for Daniel Green contacted counsel for the
Company and requested that the terms discussed at the June 14th meeting be
included in a binding letter of intent that required the Company to negotiate
exclusively with Daniel Green, provided for a financing contingency in favor of
Daniel Green and required a termination fee of $1.5 million payable to Daniel
Green in the event the parties did not reach a definitive agreement.

     On June 18, 1999, principals of the Company and its financial and legal
advisors discussed the status of negotiations. Shortly thereafter, counsel for
the Company telephoned counsel for Daniel Green and indicated that the Company
was unwilling to proceed with negotiations unless both the financing contingency
and earn-out provisions were deleted. The Company's counsel further advised that
the Company would not consider signing a binding letter of intent with a
termination fee.

     Throughout the remainder of June, 1999, counsel for Daniel Green and
counsel for the Company held discussions in an attempt to resolve outstanding
issues between the parties.

     On July 7, 1999, in response to Daniel Green's request, counsel for the
Company prepared and sent a draft Merger Agreement to counsel for Daniel Green
containing alternative proposals for a transaction that the Company could
support, subject to stockholder and Board approval.

     Throughout the remainder of July, 1999, the parties continued to try to
resolve the outstanding issues.

     During the week of August 2, 1999, Daniel Green's chief executive officer
telephoned the Company's chairman of the board to discuss the financing
contingency and the Company's reluctance to accept it. He then suggested that
Parent, which owns 35.1% of the stock of Daniel Green and of which he is also
president and chief executive officer, would be willing to purchase the Shares
owned by the Company's chairman and his family, comprising 53.3% of the
Company's outstanding Shares.

     The next day counsel for the Company telephoned counsel for Daniel Green
and indicated that the Parent's offer would have to be for all of the Company's
outstanding Shares in order for the Company to consider it.

     Thereafter, Parent's chief executive officer telephoned the Company's
chairman to indicate that Parent would be willing to make a cash tender offer
for all of the outstanding Shares if Daniel Green could not satisfy the
Company's concerns with regard to financing.

     On August 17, 1999, representatives of Daniel Green and Parent met in
Boston, Massachusetts with representatives of the Company and their respective
counsel to discuss how Daniel Green could finance a proposed tender offer and
merger with its bank commitment and support from Parent.

     On August 24, 1999, Daniel Green submitted to the Company an expression of
interest to acquire all issued and outstanding Shares at $11.75 through a cash
tender offer by a Daniel Green subsidiary and a second stage merger. A copy of
the financing commitment from Daniel Green's bank was not yet available, but a
copy of a standby financing commitment from Parent was submitted along with a
copy of current financial statements of Parent.

     On August 26, 1999, counsel for the Company advised Daniel Green's counsel
that certain aspects of Daniel Green's proposal were unacceptable. In the
meantime, president of Parent continued negotiations with Daniel Green's bank
concerning the support which the Bank would require from Parent in order for the
bank to provide its commitment to finance the Offer and the refinancing
thereafter.

                                        4
<PAGE>   6

     On August 31, 1999, Parent determined that it was unwilling to meet the
demands of Daniel Green's bank and would itself make a cash tender offer for all
of the Company's outstanding Shares.

     On September 2, 1999, Parent informed the Company that Daniel Green would
no longer pursue the acquisition of the Company, and Parent sent to the Company
its expression of interest to make a cash tender offer for all outstanding
shares of the Company at $11.75 per share, without any financing contingency.

     The Company's Board met on September 7, 1999 to consider Parent's
expression of interest and directed its officers to proceed to negotiate terms
of a definitive agreement.

     From September 8, 1999 through October 6, 1999, the parties negotiated the
terms of a Merger Agreement.

     The Company's Board met in person on October 1, 1999. All board members
attended; counsel for the Company and representatives from Advest participated
telephonically. The Board was apprised of the progress since the prior meeting
and given a detailed analysis of the status of negotiations regarding the Merger
Agreement and the proposed agreements with certain stockholders, including the
existence of "fiduciary out" provisions. The Board was apprised that (i) at
least 80% of the outstanding shares, which includes a majority of the Shares
held by stockholders other than the Company's chairman and his family, must
tender in order for the Purchaser to consummate the tender offer, and (ii) the
Purchaser had no financing contingency and was required to place all of the
Offer Consideration into escrow upon the execution of the Merger Agreement. The
Board was also apprised that Parent required that the Merger Agreement provide
for a breakup fee of up to $1.5 million (including transaction expenses) payable
to Parent in the event the Merger Agreement were terminated by Company, Parent
or Purchaser because of fiduciary duty issues. The Company's Board accepted this
provision after considering (i) that Parent provided the only viable offer after
an extensive search of potential purchasers, (ii) that Parent would not sign the
Merger Agreement without such a provision, (iii) the customary nature of breakup
fees in similar transactions, and (iv) the amount of the breakup fee in relation
to the size of the Offer. Advest then discussed the procedures and analysis it
undertakes in deriving its fairness opinion. At the conclusion of this
discussion, Advest apprised the Company's Board that it would be able to deliver
a favorable fairness opinion based upon the proposed tender offer consideration
of $11.75 per share. Next, the Board, legal counsel and Advest discussed a
number of strategic approaches to resolving open issues. In light of the fact
that there remained open issues with respect to the Merger Agreement, the Board
authorized counsel to ask Parent to increase its price above $12 per share. The
Board concluded that it would evaluate any open issues in light of Parent's
response to the requested price increase. Later that day, Company's counsel
notified Parent's counsel of the Board's request for a price increase above $12
per share.

     On October 3, 1999, counsel for Parent telephoned Company's counsel and
advised that Parent was unwilling to raise its offer above $11.75 per share.
Counsel for both sides then continued to negotiate open issues with respect to
the Merger Agreement.

     The Board reconvened telephonically on October 6, 1999. All Board members
participated in the call as well as counsel for the Company and representatives
of Advest. The Board was apprised of Parent's refusal to increase its offer
price. Counsel then updated the Board on the status of the Merger Agreement,
noting that all remaining issues had been satisfactorily resolved.

     Following a lengthy discussion of strategic alternatives, Advest rendered
its opinion that the transaction is fair to the stockholders of the Company from
a financial point of view. It was the consensus of the Board that the benefit to
the Company's stockholders from consummating the proposed Merger transaction
outweighed the risk involved, compared with the alternatives of remaining
independent or soliciting other interested bidders. It was noted that the price
of the Merger transaction was toward the high end of the Company's 52-week range
of prices, which was from $6.75 to $12.75.

     The Company's Board then unanimously (a) determined that the Merger
Agreement and the transactions contemplated thereby, including the Offer and the
Merger, are fair, adequate and in the best interests of the Company's
stockholders, (b) adopted and approved the Merger Agreement and authorized the
execution thereof by the Company, and (c) recommended that the Company's
stockholders accept the Offer and tender their Shares thereunder.
                                        5
<PAGE>   7

     In reaching the conclusions described by Advest in clause (a) above, the
Company's Board considered a number of factors including, without limitation:

          (i) The presentation to the Board, and the written opinion of Advest
     that, based upon and subject to the assumptions and qualifications stated
     therein, the consideration to be received by stockholders of the Company
     pursuant to the Offer and Merger Agreement is fair from a financial point
     of view. A copy of the written opinion is filed as Exhibit (c)(19) hereto
     and is incorporated herein by reference. Stockholders are urged to read
     such opinion carefully and in its entirety.

          (ii) Current market conditions, the relationship between the
     consideration to be received by stockholders in the Offer and the Merger on
     the one hand and the historical and recent market prices of the Shares on
     the other hand, and the fact that the market for the Shares is very
     illiquid, thus restricting the ability to sell Shares at current market
     prices.

          (iii) The Company's business, the strategic direction of the Company's
     business, the relationship of the Offer Consideration to historical and
     projected earnings, acquisition transactions involving comparable companies
     and the lack of other possible transactions that might provide greater
     value to stockholders, and the risks associated with remaining an
     independent company and engaging a qualified chief executive officer to
     replace Mr. Kagan, who has been acting as chief executive officer of the
     Company since its prior chief executive officer's untimely demise.

          (iv) The terms and conditions of the transactions contemplated by the
     Merger Agreement, as reviewed by and discussed with the Company's
     management, legal counsel and financial advisors and the fact that the
     terms of the Merger Agreement were determined through arm's-length
     negotiations between the Company's Board and its legal and financial
     advisors, on the one hand, and representatives of Parent and Purchaser, on
     the other.

          (v) The fact that the terms of the Merger Agreement allow the Board,
     if required by fiduciary duties, to withdraw its recommendation of the
     Merger and to accept an alternative acquisition proposal, upon payment of a
     negotiated breakup fee and reimbursement of expenses.

          (vi) The Company's right to exercise its fiduciary duties, subject to
     certain conditions under the Merger Agreement, in order to respond to
     requests for nonpublic information and to participate in substantive
     discussions with any person making an Acquisition Proposal as defined in
     the Merger Agreement.

          (vii) The fact that Parent and Purchaser's obligations under the Offer
     were not subject to any financing contingency, and the requirement of
     Parent and Purchaser to place the entire Offer Consideration in cash into
     escrow upon execution of the Merger Agreement.

          (viii) The fact that, unless waived by the Company, Parent and
     Purchaser cannot consummate the Offer unless the Minimum Condition is
     satisfied, which requires that more than a majority of the Shares held by
     stockholders other than the Company's chairman and his family be tendered
     and not withdrawn in the Offer.

          (ix) The fact that the Company's Board can waive the Minimum
     Condition.

          (x) The ability of stockholders to seek a "fair price" for their
     Shares upon consummation of the Offer in accordance with Section 910 of the
     Maine Business Corporation Act (the "MBCA") and the availability of
     dissenters' rights in the Merger in accordance with Section 909 of the
     MBCA.

          (xi) The reasons for not undertaking a formal public "auction" or
     other similar public process, including the potential disruption to the
     Company's business, management and employees if an auction were pursued.

determine that any factor was of particular importance. Rather, the Board views
its position and recommendations as being based on the totality of the
information presented to it and considered by it.

     OPINION OF FINANCIAL ADVISOR.  The Company's Board retained Advest to act
as its financial advisor and to render an opinion to the Board as to the
fairness from a financial point of view of the consideration to be received by
stockholders of the Company in the Offer and the Merger. On October 6, 1999,
Advest delivered the fairness opinion to the Board, which was later confirmed in
writing, to the effect that, as of such date, the consideration to be received
by stockholders in the Offer and the Merger was fair, from a financial point of
view, to the stockholders of the Company. The fairness opinion contains certain
important qualifications and a description of assumptions made, matters
considered, areas of reliance on others on the review undertaken by Advest, and
is incorporated herein in its entirety. THE FAIRNESS OPINION, WHICH IS LIMITED
TO AN ASSESSMENT, AS OF ITS DATE, OF THE FAIRNESS OF THE PROPOSED CONSIDERATION
FROM A FINANCIAL POINT OF VIEW, IS ADDRESSED TO THE BOARD FOR ITS USE IN
CONNECTION WITH ITS REVIEW AND APPROVAL OF THE MERGER AGREEMENT, AND DOES NOT
CONSTITUTE A RECOMMENDATION AS TO HOW ANY HOLDER OF SHARES SHOULD VOTE WITH
RESPECT TO THE MERGER, OR WHETHER OR NOT ANY HOLDER OF SHARES SHOULD TENDER SUCH
SHARES IN THE OFFER.

ITEM 5.  PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED

     The Company retained Advest, Inc. as its financial advisor in connection
with the transaction contemplated by the Merger Agreement, including delivery of
a written opinion as to the fairness to the Company's stockholders, from a
financial point of view, of the consideration to be received pursuant to the
Offer and Merger. Pursuant to the terms of Advest's engagement, the Company has
agreed to reimburse Advest for its out-of-pocket expenses up to $15,000 and has
agreed to pay Advest the following fees: an initial non-refundable retainer of
$15,000; a non-refundable monthly retainer of $7,500 until termination of the
Advest engagement; $50,000 upon delivery of Advest's written fairness opinion to
the Company's Board of Directors; and a Success Fee of approximately $430,000
(less the foregoing retainer and opinion fees paid to Advest), payable upon and
subject to consummation of the Merger. Payment of the Success Fee is subject to
consummation of the Merger, and the Board was aware of this fee structure and
took it into account in considering the Advest fairness opinion. The Company has
also agreed to indemnify Advest and certain related persons and entities against
certain liabilities, including liabilities under the federal securities laws,
relating to or arising out of its engagement by the Company. In the ordinary
course of its business, Advest and its affiliates may actively trade in the
shares of the Company for their own account and for the account of their
customers and, accordingly, may at any time hold a long or short position in
such securities.

ITEM 6.  RECENT TRANSACTIONS WITH RESPECT TO SECURITIES

     (a) During the past 60 days, no transactions in Shares have been effected
by the Company or, to the best of the Company's knowledge, by any of its
executive officers, directors, affiliates or subsidiaries.

     (b) To the best of the Company's knowledge, to the extent permitted by
applicable securities laws, rules or regulations, each executive officer,
director and affiliate of the Company presently intends to tender to the
Purchaser, pursuant to the Offer, all Shares held of record or beneficially
owned by him or it.

ITEM 7.  CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY

     (a) Except as set forth in this Schedule 14D-9, no negotiation is being
undertaken or is underway by the Company in response to the Offer that relates
to or would result in (i) an extraordinary transaction, such as a merger or
reorganization, involving the Company or any subsidiary of the Company; (ii) a
purchase, sale, or transfer of a material amount of assets by the Company or any
subsidiary of the Company; (iii) a tender offer for or other acquisition of
securities by or of the Company; or (iv) any material change in the present
capitalization or dividend policy of the Company.

     (b) Except as set forth in this Schedule 14D-9, there is no transaction,
board resolution, agreement in principle or signed contract in response to the
Offer that relates to or would result in one or more of the events referred to
in Item 7(a) above.

ITEM 8.  ADDITIONAL INFORMATION TO BE FURNISHED

MAINE BUSINESS CORPORATION ACT

     The Company is incorporated under the laws of the State of Maine. In
general, Section 611-A of the Maine Business Corporation Act (the "MBCA")
prevents an "interested stockholder" (generally, a person who owns or has the
right to acquire 25% or more of a corporation's outstanding voting stock, or an
affiliate or associate thereof) from engaging in a "business combination"
(defined to include mergers and certain other transactions) with a Maine
corporation for a period of five years following the date such person became an
interested stockholder unless prior to such date the board of directors of the
corporation approved the business combination. The Company's board of directors
has approved the business combination contemplated by the Merger Agreement.
Parent has informed the Company that neither it nor, to its knowledge, any of
its affiliates owns any Shares. Accordingly, the Company believes that Section
611-A is inapplicable to the Offer and the Merger.

     Upon the purchase of at least 25% of the Shares, Purchaser will be deemed a
"controlling person" under Section 910 of the MBCA and a "control transaction"
shall have occurred. As a result, holders of Shares which have not been tendered
and purchased in the Offer, shall, upon consummation of the Offer, have the
right to demand that Purchaser pay "fair value" for those Shares in cash, as
determined in accordance with Section 910 of the MBCA. A copy of Section 910 is
attached to the Offer to Purchase as Schedule II and a general description of a
stockholder's rights is set forth under the heading "Certain Legal Matters and
Regulatory Approvals; Control Transaction Payment Rights" in the Offer to
Purchase. Schedule II to the Offer the Purchase and the disclosure set forth
under "Certain Legal Matters and Regulatory Approvals; Control Transaction
Payment Rights" are incorporated herein by reference.

DISCLAIMER

     The information contained in this Schedule 14D-9 concerning Parent,
Purchaser, the Offer and the Merger was supplied by Purchaser. The Company takes
no responsibility for the completeness or accuracy of such information.

(1) Mr. Hansen passed away on December 27, 1998.

(2) Represents excess life insurance valuations, except with respect to Paul
    Hansen, which also included automobile allowance.

Bonuses are awarded pursuant to an incentive plan adopted by the Board of
Directors of the Company. The objective of the incentive plan in 1996, 1997 and
1998 was to reward the Company's employees when, in the discretion of the Board
of Directors, the Company outperformed certain standards set by the Board. These
standards, which included standards for net sales and operating profits, were
achieved in 1996 and 1998. These standards were not achieved in 1997, and
accordingly no bonus pool was funded. The Pool was allocated among employees
based on each individual's contribution to the Company's performance as
determined by the Board of Directors in its unilateral discretion.

     Upon the death of any employee who has served the Company for at least 15
years and has been an officer and/or director of the Company and/or any
subsidiary for at least two years, the Company will pay the sum of $5,000 and
one year's salary to the employee's surviving spouse and minor children. Mr.
Wilhelm Pfander, Vice President of Manufacturing currently qualifies for these
benefits, and the Company is currently making payment to Mr. Hansen's widow
pursuant to this plan.

     Mr. Kagan, Chairman of the Board of Directors, retired as Chief Executive
Officer of the Company on December 31, 1993. On November 26, 1993, the Board of
Directors voted to provide him a supplemental retirement benefit of $20,000 per
year. During 1998, Mr. Kagan received payments totaling $20,000 as a result of
this supplemental retirement benefit.

     The compensation for each outside director in fiscal 1998 consisted of an
annual retainer of $7,500 and a payment of $500 for each meeting attended. In
addition, the Chairman of the Board receives an annual retainer of $20,000.
Director compensation for fiscal 1999 is expected to continue at this rate.

CONTRIBUTORY RETIREMENT PLAN

     Since 1981, Penobscot Shoe Company has had a contributory retirement plan
covering substantially all employees. This is a defined benefit plan and the
amount of the Company's contribution with respect to specified persons cannot be
readily calculated by the actuaries of the plan. The annual retirement benefits
for each pension plan year of future service are determined as .85% of annual
earnings which are not in excess of $16,200, and 1.5% of any excess of annual
earnings over $16,200. Past service (prior to January 1, 1988) benefits are
determined for each year of credited past service as .65% of average earnings of
the three years ended January 1, 1988 up to $16,200 and 1.5% of the average over
$16,200.

                                       A-4
<PAGE>   16

     All employees who are enrolled as members of the pension plan have
contributed in each plan year 0.5% of their annual earnings up to $16,200, and
2.5% of their annual earnings in excess of $16,200. Effective January 1, 1999,
the Plan was amended to eliminate the requirement that employees contribute to
the Plan. The following table shows the annual pension benefit payable to
employees, including officers, retiring at age 65 using a constant salary. The
table includes past and future service as follows: for 15 years service, 10
years of past service and 5 years of future service; for 25 years service, 20
and 5 respectively; for 30 years service, 25 and 5 respectively; for 35 years
service, 30 and 5; for 45 years service, 40 and 5.

1991 STOCK OPTION PLAN

     The Company's 1991 Stock Option Plan (the "Plan") was adopted by the Board
of Directors on December 20, 1990 and approved by the Company's stockholders at
the 1991 annual meeting. The Plan provides that options for the purchase of up
to 75,000 shares of Common Stock may be granted, of which 33,000 shares remained
available at December 1, 1998. The Plan is intended to promote the growth and
profitability of the Company by providing key employees with additional
incentive to achieve the Company's objectives and to enable the Company to
attract and retain key employees of outstanding ability.

     The Plan is administered by the Compensation Committee of the Board of
Directors (the "Committee"), which has the authority to designate the key
employees eligible to participate, to prescribe the number of shares and other
terms of awards, to interpret the Plan and to make rules and regulations and all
other determinations for administering the Plan. None of the Directors
constituting the Committee is eligible to receive any stock options pursuant to
the Plan.

     The exercise price of all options granted by the Committee will not be less
than 100% of the fair market value of the Common Stock on the date the option is
granted. All options granted under the Plan must expire ten years after the date
they were granted unless provision is made for an earlier expiration. No option
may be granted later than ten years following the date the Plan was approved by
the Board of Directors. The full purchase price for shares acquired upon the
exercise of an option must be paid in cash, Common Stock, or the promissory note
of the participant containing such terms as the Committee shall specify, or a
combination thereof, as the Committee may determine.

     If the optionee ceases to serve the Company for reasons other than death or
total and permanent disability, the optionee may exercise his or her option for
a period equal to the earlier to occur of the end of such exercise right as set
forth in the option, or three months following such termination, to the extent
the option was exercisable prior to termination. Except as so exercised, the
option expires at the end of such three month period. If the optionee, while in
the service of the Company, dies or becomes permanently and totally

                                       A-5
<PAGE>   17

disabled at any time while he or she is entitled to exercise an option, the
optionee or his or her executor, administrator, heir or legatee may exercise the
option in full at any time up to one year following the date of such termination
or the end of the tenth year following the grant of the option, if earlier.
Options may be granted on terms different from those set forth in the Plan in
substitution for options held by employees of other companies who become
employees of the Company or a subsidiary as a result of a merger or other
acquisition transaction.

     Options may not be transferred by an optionee otherwise than by will or by
the laws of descent and distribution and during the optionee's lifetime can be
exercised only by the optionee.

     In the event that there is a change of control of the Company, as defined
in the Plan, each option held pursuant to the Plan will become fully
exercisable. In the event of a stock dividend, stock split, recapitalization or
other change in the Company's capital stock, the number and kind of shares of
stock or other securities subject to an option granted hereunder, and the
maximum number of shares or other securities available under the Plan, the
purchase price, and other relevant provisions, may be appropriately adjusted by
the Committee. The Committee may also make such adjustments in the event of a
material change in accounting principles or practices, a consolidation or merger
where the Company survives, a sale or acquisition of significant amounts of
stock or other property, or the occurrence of any other event, if determined by
the Committee to warrant such an adjustment to avoid distortion of the Plan.

     Subject to the provision dealing with changes in control, if the Company is
involved in a merger or consolidation in which it is not the surviving
corporation, or the Company's shares are converted into, or exchanged for, the
shares of another corporation, or into or for other consideration, all options
granted under the Plan shall terminate upon such event. However, if such an
event occurs, the Committee shall cause replacement options to be granted or
make all outstanding options exercisable in full for a period of twenty days
prior to such event.

     The Committee may amend the Plan and any option granted thereunder,
provided that, without the approval of the Stockholders of the Company, no
amendment may (except in the event of stock dividends, stock splits, certain
mergers, spin-offs, and similar events, as herein provided) increase the maximum
number of shares available under the Plan, the designation of those eligible to
participate in the Plan, reduce the minimum option price of future options, or
extend the time within which options may be granted. No amendment may adversely
affect the rights of any optionee without his or her consent.

     All grants of options under the Plan or their exercise shall be in
accordance with applicable federal and state laws and regulations, and the
Company may impose such conditions and requirements as it deems necessary or
desirable to assure such compliance.

     The Plan is not intended to qualify for incentive stock option tax
treatment under the Internal Revenue Code.

     No options were granted during fiscal 1998.

To the Holders of Common Stock of Penobscot Shoe Company:

                                  INTRODUCTION

     PSC Acquisition Corp., a corporation organized and existing under the laws
of the State of Maine ("Purchaser") and an indirect wholly-owned subsidiary of
Riedman Corporation, a corporation organized and existing under the laws of the
State of New York ("Parent"), hereby offers to purchase all of the outstanding
shares of common stock, par value $1.00 per share (the "Shares" or "Company
Common Stock"), of Penobscot Shoe Company, a corporation organized and existing
under the laws of the State of Maine (the "Company"), at a price of $11.75 per
Share (such amount, or any greater amount per Share paid pursuant to the Offer,
being hereinafter referred to as the "Offer Price"), net to the seller in cash
(subject to applicable withholding of taxes), without interest, upon the terms
and subject to the conditions set forth in this Offer to Purchase and in the
related Letter of Transmittal (which, together with any amendments or
supplements hereto or thereto, collectively constitute the "Offer").

     Tendering stockholders who have Shares registered in their own name and who
tender directly to the Depository will not be obligated to pay brokerage fees or
commissions or, except as otherwise provided in Instruction 6 -- "Stock Transfer
Taxes" of the Letter of Transmittal, stock transfer or other similar taxes with
respect to the purchase of Shares by Purchaser pursuant to the Offer. Purchaser
will pay all charges and expenses of EquiServe, L.P., which is acting as the
Depository (in such capacity, the "Depository") and Georgeson Shareholder
Communications Inc. which is acting as the information agent (in such capacity,
the "Information Agent") incurred in connection with the Offer. See Section
15 -- "Fees and Expenses".

     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT PROPERLY WITHDRAWN, PRIOR TO THE EXPIRATION OF THE OFFER, AT
LEAST 80% OF THE TOTAL ISSUED AND OUTSTANDING SHARES OF COMPANY COMMON STOCK
(THE "MINIMUM CONDITION"). THE OFFER IS ALSO SUBJECT TO CERTAIN OTHER TERMS AND
CONDITIONS CONTAINED IN THIS OFFER TO PURCHASE. SEE SECTION 1 -- "TERMS OF THE
OFFER; EXPIRATION DATE" AND SECTION 13 -- "CERTAIN CONDITIONS OF THE OFFER",
WHICH SETS FORTH IN FULL THE CONDITIONS TO THE OFFER.

     The purpose of the Offer, which is being made pursuant to an Agreement and
Plan of Merger, dated as of October 6, 1999 (the "Merger Agreement"), by and
among Purchaser, Parent and the Company is to acquire for cash as many
outstanding Shares as possible as a first step in acquiring the entire equity in
the Company. The Merger Agreement provides, among other things, that as promptly
as practicable following the completion of the Offer and the satisfaction or
waiver of certain conditions set forth in the Merger Agreement and in accordance
with the relevant provisions of the Maine Business Corporation Act ("Maine
Law"), the Company will be merged with and into the Purchaser (the "Merger").
Upon consummation of the Merger, the Company will continue as the surviving
corporation (the "Surviving Corporation") and will be an indirect wholly-owned
subsidiary of Parent. At the effective time of the Merger (the "Effective
Time"), each issued and outstanding Share (other than (i) Shares owned by
Parent, Purchaser or any direct or indirect wholly owned subsidiary of the
Company or Parent immediately prior to the effective time of the Merger
("Ineligible Shares") and (ii) Shares which are issued and outstanding
immediately prior to the Effective Time and which are held by stockholders who
have (A) properly exercised appraisal rights with respect thereto ("Dissenting
Shares") in accordance with Section 909 of Maine Law or (B) properly exercised
the right to receive payment therefor following a control transaction in
accordance with Section 910 of Maine Law ("Demanding Shares")), will be
converted into and represent the right to receive the Offer Price, without
interest (the "Merger Price"). See Section 10 -- "Background of the Offer;
Contacts with the Company; The Merger Agreement; The Tender Agreements".

     THE BOARD OF DIRECTORS OF THE COMPANY (THE "BOARD") HAS UNANIMOUSLY
APPROVED THE MERGER AGREEMENT, THE OFFER AND THE MERGER, AND HAS DETERMINED THAT
THE OFFER AND THE MERGER ARE FAIR TO AND IN THE BEST INTERESTS OF THE COMPANY'S
STOCKHOLDERS. THE BOARD UNANIMOUSLY RECOMMENDS THAT
                                        3
<PAGE>   4

THE COMPANY'S STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES IN THE
OFFER.

     Advest, Inc. ("Advest"), the financial advisor to the Company, has
delivered a written opinion to the Board to the effect that, as of the date of
such opinion and based upon and subject to certain matters described therein,
the $11.75 per Share cash consideration to be received by the holders of the
Shares in the Offer and the Merger is fair, from a financial point of view, to
such holders. A copy of such opinion is attached as an exhibit to the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9"),
which has been filed by the Company with the Securities and Exchange Commission
(the "Commission" or the "SEC") in connection with the Offer and which is being
mailed to shareholders herewith, and should be read carefully in its entirety
for a description of the assumptions made, matters considered and limitations on
the review undertaken by Advest.

     In connection with the execution of the Merger Agreement, Parent and
Purchaser entered into Tender Agreements (the "Tender Agreements"), dated as of
October 6, 1999, among Parent, Purchaser and Irving Kagan, his sister, Mildred
Striar, and certain other family members (collectively, the "Principal
Stockholders"), pursuant to which each of the Principal Stockholders has, among
other things, agreed to tender into the Offer all Shares owned by them and not
withdraw their tenders prior to the expiration of the Offer. As of September 30,
1999, the 740,321.5 Shares owned by the Principal Stockholders and subject to
the Tender Agreements constituted approximately 53.33% of the total issued and
outstanding Shares of the Company. Thus, the Principal Stockholders' tender of
their Shares pursuant to the Tender Agreements will not be sufficient to satisfy
the Minimum Condition. The Minimum Condition should be satisfied if at least
approximately 370,311 Shares are validly tendered and not withdrawn prior to the
expiration of the Offer, in addition to the 740,321.5 that will be tendered
pursuant to the Tender Agreements. See Section 10 -- "Background of the Offer;
Contacts with the Company; The Merger Agreement; The Tender Agreements".

     The Merger Agreement provides that so long as it is in effect, the Company
shall not cause or permit the size of the Board to be expanded to more than five
directors. The Merger Agreement also provides that promptly upon satisfaction of
the Minimum Condition and the purchase of and payment for Shares in the Offer by
Parent or any of its subsidiaries, if requested by Parent, Parent will be
entitled to designate three directors for election to Company's five person
Board. The Company will, upon request of and as specified by Purchaser or
Parent, on the date of such request, secure the resignations of such number of
its incumbent directors as is necessary to enable Parent's designees to be so
elected to the Board, and will take all actions necessary to cause Parent's
designees to be so elected or appointed. At such times, the Company will use its
best efforts to cause individuals designated by Parent to constitute the same
percentage of each committee of the Board (other than any committee of the Board
established to take action under the Merger Agreement). Notwithstanding the
foregoing, until the Effective Time, the Company will retain as members of its
Board at least two directors who are directors of the Company on the date of the
Merger Agreement; provided, that upon satisfaction of the Minimum Condition and
subsequent to the purchase of and payment for Shares pursuant to the Offer,
Parent will always have its designees represent at least a majority of the
entire Board. See Section 10 -- "Background of the Offer; Contacts with the
Company; The Merger Agreement; The Tender Agreements".

     The consummation of the Merger is subject to the satisfaction or waiver of
certain conditions, including the approval and adoption of the Merger Agreement
by the requisite vote of the stockholders of the Company, if required under
Maine Law. See Section 10 -- "Background of the Offer; Contacts with the
Company; The Merger Agreement; The Tender Agreements". If so required, a Proxy
Statement (as defined in Section 10 -- "Background of the Offer; Contacts with
the Company; The Merger Agreement; The Tender Agreements") containing detailed
information concerning the Merger will be furnished to stockholders of the
Company in connection with a special meeting of its stockholders to be called by
the Company to vote on the Merger. Purchaser will vote all Shares acquired
pursuant to the Offer in favor of the Merger. Maine law requires, among other
things, that the adoption of any plan of merger or consolidation of the Company
must be approved by the Board and by the holders of a majority of the
outstanding shares, unless a corporation's charter or by-laws provides for a
higher percentage. The Company's By-Laws require the approval of 55% of the
outstanding Shares to consummate a merger. Consequently, if the Offer is closed
after achieving the
                                        4
<PAGE>   5

Minimum Condition (tender of 80% of the outstanding Shares), Purchaser will have
sufficient voting power to approve and adopt the Merger Agreement and the Merger
without the vote of any other stockholder. Notwithstanding the foregoing, if
Parent and Purchaser collectively own, following consummation of the Offer, at
least 90% of the outstanding Shares, Parent, Purchaser and the Company will
cause the Merger to become effective as soon as practicable, without a meeting
of the stockholders of the Company, in accordance with the "short-form" merger
provisions of Section 904 of Maine Law, if possible.

     THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION AND SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE
WITH RESPECT TO THE OFFER.

1. TERMS OF THE OFFER; EXPIRATION DATE.

     Upon the terms and subject to the conditions of the Merger Agreement and
the Offer (including if the Offer is extended or amended, the terms and
conditions of such extension or amendment), Purchaser will accept for payment
and pay for all Shares validly tendered prior to the Expiration Date (as defined
below) and not properly withdrawn as permitted by Section 4 -- "Withdrawal
Rights". The term "Expiration Date" means 12:00 Midnight, Eastern Standard Time,
on November 9, 1999; provided, however, that Purchaser may, without the consent
of the Company (but subject to the terms and conditions of the Merger Agreement,
as described below), extend the period during which the Offer is open, in which
event the term "Expiration Date" will mean the latest time and date at which the
Offer, as so extended by Purchaser, will expire.

     Purchaser is entitled to extend the Offer (and defer the Expiration Date)
up to 90 days after the Offer commences, in one or more periods of not more than
10 business days each, if at the initial expiration date of the Offer, or any
extension thereof, any condition to the Offer is not satisfied or waived
("Extension A"). Purchaser also is entitled, but shall be under no obligation,
to extend the Offer (and to defer the Expiration Date) further for an additional
period ending no more than 150 days (in one or more periods of not more than 10
business days each) following an extension pursuant to Extension A, if at the
Expiration Date, as deferred pursuant to Extension A, the Litigation Condition
or the Trading Suspension Condition (as defined in Section 13 -- "Certain
Conditions to the Offer") have not been satisfied or waived. Purchaser is
further entitled to extend the Offer for any period required by rule,
regulation, interpretation or position of the Commission or the Staff thereof
which is applicable to the Offer. Furthermore, at the Expiration Date, if all
conditions to the Offer have been satisfied or waived, and for so long as less
than 90% of the outstanding shares of Company Common Stock have been validly
tendered and not properly withdrawn pursuant to the Offer, Purchaser may, in its
sole discretion and without the consent of the Company, extend the Offer (and
defer the Expiration Date) for up to an additional 10 business days in the
aggregate (in periods of no more than five business days each). In addition, the
Offer Price may be increased and the Offer may be extended to the extent
required by law in connection with such increase without the consent of the
Company. Any extension of the Offer in accordance therewith shall defer the
Expiration Date until the latest date to which the Offer is so extended but not
beyond those dates set forth above. Notwithstanding the foregoing, subject to
the other terms of the Merger Agreement (including Parent's and Purchaser's
right to terminate the Agreement) if any conditions other than the Minimum
Condition have not been satisfied or waived as of a scheduled Expiration Date,
and such conditions are reasonably capable of being satisfied by December 31,
1999, then Purchaser is required to continue to extend the Offer through such
date in intervals of no less than five business days each. During any such
extension, all Shares previously tendered and not withdrawn will remain tendered
pursuant to the Offer, subject to the rights of a tendering stockholder to
withdraw his, her or its Shares. See Section 4 -- "Withdrawal Rights".

     Subject to the applicable regulations of the Commission, Purchaser also
expressly reserves the right, in its sole discretion (but subject to the terms
and conditions of the Merger Agreement), at any time and from time to time, (i)
to delay acceptance for payment of, or, regardless of whether such Shares were
theretofore accepted for payment, payment for, any Shares, or to terminate the
Offer and not accept for payment, or not pay for, any Shares if, at the
Expiration Date, any of the conditions specified in Section 13 -- "Certain
Conditions of the Offer" exists and (ii) to waive any of the conditions
specified in Section 13 -- "Certain

                                        5
<PAGE>   6

Conditions of the Offer", in whole or in part. The Merger Agreement provides
that, without the consent of the Company, Purchaser will not (i) decrease the
Offer Price, (ii) change the form of consideration payable in the Offer, (iii)
reduce the number of Shares sought to be purchased in the Offer, (iv) amend the
conditions to the Offer set forth in Section 13 -- "Certain Conditions of the
Offer" or impose conditions to the Offer in addition to those set forth in
Section 13 -- "Certain Conditions of the Offer" or (v) amend or waive the
Minimum Condition to be less than 80% of the total issued and outstanding shares
of Company Common Stock. Purchaser is required under the Merger Agreement
promptly after expiration of the Offer to accept for payment, and pay for, all
Shares validly tendered and not withdrawn, subject to the terms and conditions
of the Offer and the Merger Agreement.

     Any extension, delay, termination, waiver or amendment will be followed as
promptly as practicable by public announcement thereof, such announcement in the
case of an extension to be made no later than 9:00 a.m., Eastern Standard Time,
on the next business day after the previously scheduled Expiration Date. Subject
to applicable law (including Rules 14d-4(c) and 14d-6(d) under the Exchange Act,
which require that material changes be promptly disseminated to stockholders in
a manner reasonably designed to inform them of such changes) and without
limiting the manner in which Purchaser may choose to make any public
announcement, Purchaser will have no obligation to publish, advertise or
otherwise communicate any such public announcement other than by issuing a press
release to the Dow Jones News Service.

     If Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer, Purchaser will extend the Offer to the extent required by Rules 14d-4(c),
14d-6(d) and 14e-1(d) under the Exchange Act. These rules generally provide that
the minimum period during which a tender offer must remain open following a
material change in the terms of the offer or information concerning the offer,
other than a change in price or a change in percentage of securities sought,
will depend upon the facts and circumstances, including the relative materiality
of the changes in the terms or information. In the Commission's view, an offer
should remain open for a minimum of five business days from the date a material
change is first published, sent or given to securityholders. With respect to a
change in price or a change in percentage of securities sought, a minimum ten
business day period is generally required to allow for adequate dissemination to
shareholders and for investor responses.

     Subject to the terms of the Merger Agreement, if, prior to the Expiration
Date, Purchaser should decide to increase the consideration being offered in the
Offer or, subject to the Company's consent, to decrease the number of Shares
being sought or the consideration being offered in the Offer, such decrease in
the number of Shares being sought or such increase or decrease in the
consideration being offered will be applicable to all stockholders whose Shares
are accepted for payment pursuant to the Offer. If at the time notice of any
such decrease in the number of Shares being sought or such increase or decrease
in the consideration being offered is first published, sent or given to holders
of such Shares, the Offer is scheduled to expire at any time earlier than the
period ending on the tenth business day from and including the date that such
notice is first so published, sent or given, the Offer will be extended at least
until the expiration of such ten business day period. For purposes of the Offer,
a "business day" means any day, other than Saturday, Sunday or a federal
holiday, and consists of the time period from 12:01 a.m. through 12:00 Midnight,
Eastern Standard Time.

     Under no circumstances will interest on the Offer Price for the Shares be
paid, regardless of any extension of the Offer or delay in making such payment.
During any extension of the Offer, all Shares previously tendered and not
withdrawn will remain tendered pursuant to the Offer, subject to the rights of a
tendering shareholder to withdraw his Shares. See Section 4 -- "Withdrawal
Rights".

     The Company has provided Purchaser with the Company's stockholder list and
security position listings for the purpose of disseminating the Offer to holders
of Shares. This Offer to Purchase and the related Letter of Transmittal will be
mailed to record holders of Shares whose names appear on the Company's
stockholder list and will be furnished, for subsequent transmittal to beneficial
owners of Shares, to brokers, dealers, commercial banks, trust companies and
similar persons whose names, or the names of whose nominees, appear on the
stockholder list or, if applicable, who are listed as participants in a clearing
agency's security position listing.

2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES.

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), Purchaser will accept for payment, and will pay for, all Shares
validly tendered prior to the Expiration Date and not properly withdrawn as soon
as it is legally permitted to do so under applicable law. The obligations of
Purchaser to consummate the Offer and to accept for payment and to pay for all
Shares validly tendered and not properly withdrawn will be subject only to the
satisfaction or waiver of the conditions to the Offer set forth in Section
13 -- "Certain Conditions of the Offer". Subject to applicable rules of the
Commission and to the terms of the Merger Agreement, Purchaser expressly
reserves the right to delay acceptance for payment of, or payment for, Shares in
order to comply, in whole or in part, with any applicable law.

     In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depository of (i) the
certificates evidencing such Shares (the "Share Certificates") or timely
confirmation (a "Book-Entry Confirmation") of a book-entry transfer of such
Shares into the Depository's account at The Depository Trust Company (the
"Book-Entry Transfer Facility") pursuant to the procedures set forth in Section
3 -- "Procedures for Accepting the Offer and Tendering Shares", (ii) the Letter
of Transmittal (or a facsimile thereof), properly completed and duly executed,
with any required signature guarantees, or an Agent's Message (as defined below)
in connection with a book-entry transfer, and (iii) any other documents required
by the Letter of Transmittal. Accordingly, payment may be made to tendering
stockholders at different times if delivery of the certificates and other
required documents occur at different times.

     The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depository and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility has
received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares, that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that Purchaser
may enforce such agreement against such participant.

     Purchaser has deposited $16,312,419 in escrow with Manufacturers and
Traders Trust Company (the "Escrow Agent") which will upon the terms and
conditions set forth in the Escrow Agreement transmit the funds to the
Depository to pay the Offer Price for all of Company's issued and outstanding
Shares tendered, not withdrawn and accepted for payment by Purchaser pursuant to
the Offer upon satisfaction or waiver of all conditions to the Offer. Any
determination concerning the satisfaction of such terms and conditions shall be
within the sole discretion of Purchaser. For purposes of the Offer, Purchaser
will be deemed to have accepted for payment (and thereby purchased) Shares
validly tendered and not properly withdrawn as, if and when Purchaser gives oral
or written notice to the Depository of Purchaser's acceptance for payment of
such Shares pursuant to the Offer. The Depository will act as agent for
tendering stockholders for the purpose of receiving payments from Purchaser and
transmitting such payments to tendering stockholders whose Shares have been
accepted for payment. Under no circumstances will interest on the purchase price
for Shares be paid, regardless of any extension of the Offer or any delay in
making such payment.

     If any tendered Shares are not accepted for payment for any reason pursuant
to the terms and conditions of the Offer, Share Certificates evidencing
unpurchased Shares will be returned, without expense to the tendering
stockholder (or, in the case of Shares tendered by book-entry transfer into the
Depository's account at the Book-Entry Transfer Facility pursuant to the
procedures set forth in Section 3 -- "Procedures for Accepting the Offer and
Tendering Shares", such Shares will be credited to an account maintained at such
Book-Entry Transfer Facility), as promptly as practicable following the
expiration or termination of the Offer.

3. PROCEDURES FOR ACCEPTING THE OFFERING AND TENDERING SHARES.

     VALID TENDER.  In order for a holder of Shares to validly tender Shares
pursuant to the Offer, the Letter of Transmittal (or a facsimile thereof),
properly completed and duly executed, together with any required signature
guarantees, or an Agent's Message in connection with a book-entry transfer of
Shares, and any other documents required by the Letter of Transmittal, must be
received by the Depository at one of its addresses set forth on the back cover
of this Offer to Purchase prior to the Expiration Date and either (i) the Share
                                        7
<PAGE>   8

Certificates evidencing tendered Shares must be received by the Depository at
such address or such Shares must be tendered pursuant to the procedures for
book-entry transfer described below and a Book-Entry Confirmation must be
received by the Depository, in each case prior to the Expiration Date, or (ii)
the tendering stockholder must comply with the guaranteed delivery procedures
described below.

     If Certificates are forwarded to the Depository in multiple deliveries, a
properly completed and duly executed Letter of Transmittal (or manually signed
facsimile thereof) must accompany each delivery. No alternative, conditional or
contingent tenders will be accepted.

     BOOK-ENTRY TRANSFER.  The Depository will establish an account with respect
to the Shares at the Book-Entry Transfer Facility for purposes of the Offer
within two business days after the date of this Offer to Purchase. Any financial
institution that is a participant in the system of the Book-Entry Transfer
Facility may make a book-entry delivery of Shares by causing such Book-Entry
Transfer Facility to transfer such Shares into the Depository's account at such
Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's procedures for such transfer. However, although delivery of Shares
may be effected through book-entry transfer at the Book-Entry Transfer Facility,
the Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, together with any required signature guarantees, or an Agent's Message
in connection with a book-entry transfer, and any other required documents,
must, in any case, be received by the Depository at its address set forth on the
back cover of this Offer to Purchase prior to the Expiration Date, or the
tendering stockholder must comply with the guaranteed delivery procedures
described below. DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY DOES
NOT CONSTITUTE DELIVERY TO THE DEPOSITORY.

     THE METHOD OF DELIVERY OF SHARE CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER FACILITY, IS AT
THE OPTION AND RISK OF THE TENDERING STOCKHOLDER, AND THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITORY. IF DELIVERY IS BY
MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.

     SIGNATURE GUARANTEES.  Signatures on all Letters of Transmittal must be
guaranteed by a firm which is a member of the Security Transfer Agents Medallion
Program, or by any other "eligible guarantor institution," as such term is
defined in Rule 17Ad-15 under the Exchange Act (each of the foregoing being
referred to as an "Eligible Institution"), except in cases where Shares are
tendered (i) by a registered holder of Shares who has not completed either the
box entitled "Special Payment Instructions" or the box entitled "Special
Delivery Instructions" on the Letter of Transmittal or (ii) for the account of
an Eligible Institution. If a Share Certificate is registered in the name of a
person other than the person who or that signs the Letter of Transmittal, or if
payment is to be made, or a Share Certificate not accepted for payment or not
tendered is to be returned, to a person other than the registered holder(s),
then the Share Certificate must be endorsed or accompanied by appropriate stock
powers, in either case signed exactly as the name(s) of the registered holder(s)
appear on the Share Certificate, with the signature(s) on such Share Certificate
or stock powers guaranteed by an Eligible Institution. See Instruction
1 -- "Guarantee of Signatures" and Instruction 5 -- "Signatures on Letter of
Transmittal; Stock Powers and Endorsements" of the Letter of Transmittal.

     GUARANTEED DELIVERY.  If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's Share Certificates evidencing such Shares are
not immediately available or such stockholder cannot deliver the Share
Certificates and all other required documents to the Depository prior to the
Expiration Date, or such stockholder cannot complete the procedures for delivery
by book-entry transfer on a timely basis, such Shares may nevertheless be
tendered, provided that all the following conditions are satisfied:

          (i) such tender is made by or through an Eligible Institution;

                                        8
<PAGE>   9

          (ii) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form made available by Purchaser, is
     received by the Depository prior to the Expiration Date as provided below;
     and

          (iii) the Share Certificates (or a Book-Entry Confirmation) evidencing
     all tendered Shares, in proper form for transfer, in each case together
     with the Letter of Transmittal (or a facsimile thereof), properly completed
     and duly executed, with any required signature guarantees (or, in the case
     of a book-entry transfer, an Agent's Message), and any other documents
     required by the Letter of Transmittal, are received by the Depository
     within three American Stock Exchange ("AMX") trading days after the date of
     execution of such Notice of Guaranteed Delivery. A "trading day" is any day
     on which trading occurs on the American Stock Exchange.

     The Notice of Guaranteed Delivery may be delivered by hand or mail or
transmitted by telegram or facsimile transmission to the Depository and must
include a guarantee by an Eligible Institution in the form set forth in the form
of Notice of Guaranteed Delivery made available by Purchaser.

     In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depository of (i) the
Share Certificates evidencing such Shares, or a Book-Entry Confirmation of the
delivery of such Shares, (ii) the Letter of Transmittal (or a manually signed
facsimile thereof), properly completed and duly executed, with any required
signature guarantees (or, in the case of a book-entry transfer, an Agent's
Message), and (iii) any other documents required by the Letter of Transmittal.

     DETERMINATION OF VALIDITY.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any tender
of Shares will be determined by Purchaser in its sole discretion, which
determination will be final and binding on all parties. Purchaser reserves the
absolute right to reject any and all tenders determined by it not to be in
proper form or the acceptance for payment of which may, in the opinion of its
counsel, be unlawful. Purchaser also reserves the absolute right to waive any
condition to the Offer or any defect or irregularity in the tender of any Shares
of any particular stockholder, whether or not similar defects or irregularities
are waived in the case of other stockholders. No tender of Shares will be deemed
to have been validly made until all defects and irregularities have been cured
or waived. None of Purchaser, Parent, the Depository, the Information Agent or
any other person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification. Purchaser's interpretation of the terms and conditions of the
Offer (including the Letter of Transmittal and the instructions thereto) will be
final and binding.

     APPOINTMENT AS PROXY.  By executing the Letter of Transmittal as set forth
above, a tendering stockholder irrevocably appoints designees of Purchaser as
such stockholder's proxies, each with full power of substitution, in the manner
set forth in the Letter of Transmittal, to the full extent of such stockholder's
rights with respect to the Shares tendered by such stockholder and accepted for
payment by Purchaser (and with respect to any and all other Shares or other
securities issued or issuable in respect of such Shares on or after the date of
this Offer to Purchase). All such proxies will be considered coupled with an
interest in the tendered Shares. Such appointment will be effective when, and
only to the extent that, Purchaser accepts such Shares for payment. Upon such
acceptance for payment, all prior proxies given by such stockholder with respect
to such Shares (and such other Shares and securities) will be revoked without
further action, and no subsequent proxies may be given nor any subsequent
written consent executed by such stockholder (and, if given or executed, will
not be deemed to be effective) with respect thereto. The designees of Purchaser
will, with respect to the Shares (and such other Shares and securities) for
which the appointment is effective, be empowered to exercise all voting and
other rights of such stockholder as they in their sole discretion may deem
proper at any annual or special meeting of the Company's stockholders or any
adjournment or postponement thereof, by written consent in lieu of any such
meeting or otherwise. Purchaser reserves the right to require that, in order for
Shares to be deemed validly tendered, immediately upon Purchaser's payment for
such Shares, Purchaser must be able to exercise full voting rights with respect
to such Shares (and such other Shares and securities).

                                        9
<PAGE>   10

     The acceptance for payment by Purchaser of Shares pursuant to any of the
procedures described above will constitute a binding agreement between the
tendering stockholder and Purchaser upon the terms and subject to the conditions
of the Offer.

     BACKUP WITHHOLDING.  Under the federal income tax laws, the Depository will
be required to withhold 31% of the amount of any payments made to certain
stockholders pursuant to the Offer ("Backup Withholding") unless such
stockholder (a) is a corporation or comes within certain other exempt categories
and when required demonstrates that fact or (b) provides the Depository with
stockholder's correct taxpayer identification number and a certification that
such stockholder is not subject to backup withholding by completing the
substitute Form W-9 in the Letter of Transmittal, or otherwise complies with
applicable requirements of the Backup Withholding rules. See Instruction
9 -- "Substitute Form W-9" of the Letter of Transmittal. In addition, with
respect to any holder that is a foreign government or international
organization, the Depository will not deduct or withhold from the consideration
otherwise payable to any such holder of Shares pursuant to the Offer any amount
with respect to which such holder has timely delivered to the Depository a
properly executed Form 8709 in accordance with applicable law.

4. WITHDRAWAL RIGHTS.

     Except as otherwise provided in this Section 4 or as provided by applicable
law, tenders of Shares made pursuant to the Offer are irrevocable. Shares
tendered pursuant to the Offer may be withdrawn at any time prior to the
Expiration Date and, unless theretofore accepted for payment by Purchaser
pursuant to the Offer, may also be withdrawn at any time after the Expiration
Date. If Purchaser extends the Offer, is delayed in its acceptance for payment
of Shares or is unable to accept Shares for payment pursuant to the Offer for
any reason, then, without prejudice to Purchaser's rights under the Offer, the
Depository may, nevertheless, on behalf of Purchaser, retain tendered Shares,
and such Shares may not be withdrawn except to the extent that tendering
stockholders comply with the procedures for withdrawal described in this Section
4. Any such delay will be by an extension of the Offer to the extent required by
law.

     For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depository at
one of its addresses set forth on the back cover page of this Offer to Purchase.
Any such notice of withdrawal must specify the name of the person who tendered
the Shares to be withdrawn, the number of Shares to be withdrawn and the name of
the registered holder of such Shares, if different from that of the person who
tendered such Shares. If Share Certificates evidencing Shares to be withdrawn
have been delivered or otherwise identified to the Depository, then, prior to
the physical release of such Share Certificates, the serial numbers shown on
such Share Certificates must be submitted to the Depository and the signature(s)
on the notice of withdrawal must be guaranteed by an Eligible Institution,
unless such Shares have been tendered for the account of an Eligible
Institution. If Shares have been tendered pursuant to the procedures for
book-entry transfer as set forth in Section 3 -- "Procedures for Accepting the
Offer and Tendering Shares", any notice of withdrawal must also specify the name
and number of the account at the Book-Entry Transfer Facility to be credited
with the withdrawn Shares, in which case a notice of withdrawal will be
effective if delivered to the Depository by any method described in the first
sentence of this paragraph.

     All questions as to the form and validity (including time of receipt) of
any notice of withdrawal will be determined by Purchaser, in its sole
discretion, whose determination will be final and binding. None of Purchaser,
Parent, the Depository, the Information Agent or any other person will be under
any duty to give notification of any defects or irregularities in any notice of
withdrawal or incur any liability for failure to give any such notification.

     Any Shares properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the Offer. However, withdrawn Shares may be
re-tendered at any time prior to the Expiration Date by following one of the
procedures described in Section 3 -- "Procedures for Accepting the Offer and
Tendering Shares".

5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.

     The receipt of cash for Shares pursuant to the Offer or to the Merger will
be a taxable transaction to the stockholders of the Company for federal income
tax purposes and may also be a taxable transaction under applicable state, local
or foreign tax laws. This will be the case whether a stockholder sells Shares
pursuant to the Offer, the Merger or the control transaction payment right under
Section 910 of the Maine Law.

     A tendering stockholder whose Shares are accepted for sale pursuant to the
Offer generally will recognize gain or loss on the date the Offer is consummated
in an amount equal to the difference between such stockholder's tax basis in the
Shares accepted for purchase and the amount of cash received in exchange
therefor. A stockholder who receives cash in exchange for Shares pursuant to the
Merger will recognize gain or loss at the Effective Time in an amount equal to
the difference between such stockholder's tax basis in such Shares and the
amount of cash received in exchange therefor.

     Gain or loss will be capital gain or loss if the Shares were capital assets
in the hands of the stockholder, and will be long-term capital gain or loss if
the Shares were held by the stockholder for more than 12 months. Under present
U.S. federal law, long-term capital gains are generally taxable at a maximum
rate of 20% for individuals and 35% for corporations. Certain limitations apply
to the use of capital losses.

     The foregoing discussion may not be applicable to certain types of
stockholders, including stockholders who acquired shares pursuant to the
exercise of employee stock options or otherwise as compensation, individuals who
are not citizens or residents of the United States and foreign corporations.

     The federal income tax discussion set forth above is included for general
information only and is based upon Purchaser's understanding of present law. The
tax consequences to each stockholder will depend in part upon such stockholder's
particular situation. STOCKHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH
RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF THE OFFER AND THE MERGER TO THEM,
INCLUDING THE APPLICATION AND EFFECT OF THE ALTERNATIVE MINIMUM TAX AND STATE,
LOCAL AND FOREIGN TAX LAWS AND CHANGES IN SUCH TAX LAWS.

     On October 6, 1999, the last full trading day prior to the announcement of
the execution of the Merger Agreement and of Purchaser's intention to commence
the Offer, the closing price per Share as reported on the AMX was $11 9/16. On
October 8, 1999, the last full trading day prior to the printing of this Offer
to Purchase, the closing price per Share as reported on the AMX was $11 5/8.
STOCKHOLDERS ARE URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR THE SHARES.

     Under the terms of the Merger Agreement, the Company is not permitted to
declare or pay dividends with respect to the Shares without the prior written
consent of Parent except that the Company may pay a quarterly cash dividend not
to exceed $0.05 in the fiscal quarter ended November 30, 1999. On October 6,
1999, the Company's Board declared a quarterly dividend of $.05 payable to
holders of record of Shares on October 14, 1999. The dividend is scheduled to be
paid on October 25, 1999.

</TABLE>

     CERTAIN COMPANY PROJECTIONS.  To the knowledge of Parent and Purchaser, the
Company does not as a matter of course make public forecasts as to its future
financial performance. However, during the discussions and negotiations
described in Section 10 -- "Background of the Offer; Contacts with the Company;
The Merger Agreement; The Tender Agreements", Advest furnished Parent with
certain financial projections of the Company which Parent and Purchaser believe
are not publicly available. The financial projections were for the Company as an
independent company (i.e. without regard to the impact to the Company of a
transaction with Parent and Purchaser). Neither Parent nor Purchaser verified
the accuracy of such financial projections. According to the projections, the
Company has estimated that it will have total revenues of approximately
$21,735,000, and net income of approximately $2,167,000 for the fiscal year
ending November 26, 1999.

     IT IS THE UNDERSTANDING OF PARENT AND PURCHASER THAT THE PROJECTIONS WERE
NOT PREPARED WITH A VIEW TO PUBLIC DISCLOSURE OR COMPLIANCE WITH PUBLISHED
GUIDELINES OF THE COMMISSION OR THE GUIDELINES ESTABLISHED BY THE AMERICAN
INSTITUTE OF CERTIFIED PUBLIC ACCOUNTANTS REGARDING PROJECTIONS OR FORECASTS AND
ARE INCLUDED HEREIN ONLY BECAUSE SUCH INFORMATION WAS PROVIDED TO PARENT AND
PURCHASER. THESE FORWARD-LOOKING STATEMENTS (AS THAT TERM IS DEFINED IN THE
PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995) ARE SUBJECT TO CERTAIN RISKS
AND UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY FROM THE
PROJECTIONS. THE COMPANY HAS ADVISED PARENT AND PURCHASER THAT ITS INTERNAL
FINANCIAL FORECASTS (UPON WHICH THE PROJECTIONS PROVIDED TO PARENT AND PURCHASER
WERE BASED IN PART) ARE, IN GENERAL, PREPARED SOLELY FOR INTERNAL USE AND
CAPITAL BUDGETING AND OTHER MANAGEMENT DECISIONS, AND ARE SUBJECTIVE IN MANY
RESPECTS

                                       13
<PAGE>   14

AND THUS SUSCEPTIBLE TO INTERPRETATIONS AND PERIODIC REVISION BASED ON ACTUAL
EXPERIENCE AND BUSINESS DEVELOPMENTS. THE PROJECTIONS ALSO REFLECT NUMEROUS
ASSUMPTIONS (NOT ALL OF WHICH WERE PROVIDED TO PARENT AND PURCHASER), ALL MADE
BY MANAGEMENT OF THE COMPANY, WITH RESPECT TO INDUSTRY PERFORMANCE, GENERAL
BUSINESS, ECONOMIC, MARKET AND FINANCIAL CONDITIONS AND OTHER MATTERS, INCLUDING
EFFECTIVE TAX RATES CONSISTENT WITH HISTORICAL LEVELS FOR THE COMPANY, ALL OF

9. FINANCING OF THE OFFER AND THE MERGER.

     The Offer is not conditioned upon any financing arrangements. The total
amount of funds required by Purchaser to consummate the Offer and the Merger and
to pay related fees and expenses is estimated to be approximately $17 million.
Purchaser will obtain all of such funds from Parent in the form of capital
contributions and/or loans. Parent currently intends to provide all of such
funds by borrowing amounts under Parent's existing credit facility arranged for
Parent by Fleet National Bank. As of the date of this Offer to Purchase,
$16,312,419 has been drawn under this facility and placed into escrow with the
Escrow Agent and the aggregate commitment is available for drawdown until
December 31, 2000. The interest on borrowings is based on LIBOR plus an
applicable spread. Parent plans to repay a portion of such borrowings from the
combined operations of Parent and the Surviving Corporation. Upon request by
Purchaser, the Escrow Agent will transfer to the Depository sufficient funds
from the escrowed amount to pay stockholders for Shares that have been validly
tendered, not withdrawn and accepted for payment by Purchaser. Section
2 -- "Acceptance for Payment and Payment for Shares."

10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY;
    THE MERGER AGREEMENT; THE TENDER AGREEMENTS.

     BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY.  In January, 1999,
James R. Riedman, as Chairman and CEO of Daniel Green Company, a manufacturer
and distributor of shoes whose stock is listed on the NASDAQ Small Cap Market,
telephoned a representative of Company to extend condolences on the recent
demise of Company's CEO and to indicate an interest in discussing a possible
combination of Company and Daniel Green Company. Parent owns 35.1% of the
outstanding shares of Daniel Green Company and Mr. Riedman is President and CEO
of Parent.

     In March, 1999, a representative of Advest contacted representatives of
Daniel Green Company and advised that a Confidential Memorandum concerning the
Company would be made available to them if a Confidentiality Agreement were
signed. The Confidentiality Agreement was signed on March 18, 1999 and returned
to Advest. Advest then forwarded the Confidential Memorandum to Daniel Green
Company.

     On March 24, 1999, a representative of Daniel Green Company telephoned a
representative of Advest to inquire concerning various aspects of the
information contained in the Confidential Memorandum.

     On March 30, 1999, a representative of Daniel Green Company wrote to a
representative of Advest expressing Daniel Green's strong interest in entering
into a merger with the Company or in acquiring all of the Company's stock in a
cash acquisition. In connection with an acquisition, Daniel Green Company
indicated that it would be in a position to support a value at a substantial
premium to Company's then current trading price of $8.50 a share, contingent on
financing, due diligence, negotiation of definitive agreements and approval of
the Company's Board.

     On April 16, 1999, a representative of Daniel Green Company wrote to a
representative of Advest expressing continued interest in acquiring Company and
entering into discussions on specific terms including paying a price of $10.50 a
share for a total consideration of $14,745,000.

     On April 23, 1999, representatives of Daniel Green Company met with
representatives of the Company and Advest at Advest's offices in Boston,
Massachusetts to discuss the Confidential Memorandum and other information
concerning both Daniel Green Company and Company.

     On April 26, 1999, a representative of Daniel Green Company commenced due
diligence investigation of the Company with the materials assembled at the
Advest data room in Boston, Massachusetts.

     On April 29, 1999, Daniel Green Company wrote to a representative of Advest
outlining terms of a proposed acquisition of Company to be structured as a cash
merger. The consideration to be paid was $14,745,000 or $10.50 per share,
contingent on financing, due diligence, negotiation of definitive agreements and
approval by the Company's Board. Accompanying the letter was a letter from
Daniel Green Company's bank proposing to finance the acquisition on terms set
forth therein.

     On May 5, 1999, a representative of Daniel Green Company telephoned a
representative of Advest to inquire concerning Daniel Green Company's proposal.
The Advest representative indicated that the Company was unwilling to engage in
formal negotiations at the $10.50 per share valuation of the Company proposed by
Daniel Green.

     Throughout May 1999, the Company and Daniel Green continued to discuss a
possible merger.

     On June 7, 1999, a representative of Advest wrote to a representative of
Daniel Green Company in response to Daniel Green Company's letter of April 29th.
The letter outlined terms which would be acceptable including aggregate
consideration of $15,798,250 in cash (or $11.25 per share) plus between 600,000
and 700,000 shares of Daniel Green Company's common stock, registered and
unrestricted.

     On June 8, 1999, a representative of the Daniel Green Company telephoned a
representative of Advest and suggested a face-to-face meeting with principals of
each company.

     On June 14, 1999, representatives of Daniel Green Company and the Company
met in Rochester, New York and discussed a revised proposal wherein the
consideration would be $11.50 per share in cash, with an

                                       16
<PAGE>   17

earn-out of $.50 per share if the Company met certain performance criteria for
the fiscal year ending November 26, 1999. Among the other terms discussed was a
termination fee of $1.5 million dollars and a commitment on the part of the
Company not to solicit other bidders.

     On June 17, 1999, counsel for Daniel Green Company contacted counsel for
the Company and requested that the terms discussed at the June 14th meeting be
included in a binding letter of intent that required the Company to negotiate
exclusively with Daniel Green Company, provided for a financing contingency in
favor of Daniel Green Company and required a termination fee of $1.5 million
payable to Daniel Green Company in the event the parties did not reach a
definitive agreement.

     On June 18, 1999, counsel for the Company telephoned counsel for Daniel
Green Company and indicated that the Company was unwilling to proceed with
negotiations unless both the financing contingency and earn-out provisions were
deleted. The Company's counsel further advised that the Company would not
consider signing a binding letter of intent with a termination fee.

     Throughout the remainder of June 1999, counsel for Daniel Green Company and
counsel for the Company held discussions in an attempt to resolve outstanding
issues between the parties.

     On July 7, 1999, in response to Daniel Green Company's request, counsel for
the Company prepared and sent a draft Merger Agreement to counsel for Daniel
Green Company containing alternative proposals for a transaction that the
Company could support, subject to Board and stockholder approval.

     Throughout the remainder of July 1999, the parties continued to try to
resolve the outstanding issues.

     During the week of August 2, 1999, the chairman of Daniel Green Company
telephoned the Company's Chairman of the Board to discuss the financing
contingency and the Company's reluctance to accept it. The Chairman of Daniel
Green Company then suggested that Parent, which owns 35.1% of the stock of
Daniel Green Company and of which he is President and Chief Executive Officer,
would be willing to purchase the shares of Company stock owned by the Company's
Chairman, his sister and their children, comprising 53.33% of the Company's
stock.

     The next day the attorney for Company telephoned the attorney for Daniel
Green Company and indicated that the Parent's offer would have to be for all of
Company's stock.

     Thereafter, Parent's President telephoned Company's principal stockholder
to indicate that Parent would be willing to make a cash tender offer for all of
the outstanding stock of Company if Daniel Green Company could not satisfy the
Company's concerns with regard to financing.

     On August 17, 1999, representatives of Daniel Green Company and Parent met
in Boston, Massachusetts with representatives of Company and their respective
counsel to discuss how Daniel Green Company would finance a proposed tender
offer and merger with its bank commitment and support from Parent.

     On August 24, 1999 Daniel Green Company submitted to Company an expression
of interest to acquire all of the issued and outstanding shares of Company
common stock at $11.75 through a cash tender offer by a Daniel Green Company
subsidiary, and a second stage merger on terms specified. A copy of the
financing commitment from Daniel Green Company's bank, as requested by Company's
attorneys was not yet available, but a copy of a standby financing commitment
from Parent was submitted along with a copy of current financial statements of
Parent.

     On August 26, 1999 the attorneys for the Company advised Daniel Green
Company's attorney that certain aspects of Daniel Green's proposal were
unacceptable. In the meantime, President of Parent continued negotiations with
Daniel Green Company's bank concerning the support which the Bank required from
Parent to give the Bank's commitment to finance the Offer and the refinancing
thereafter.

     On August 31, 1999 Parent determined that it was unwilling to meet the
demands of Daniel Green Company's bank and would itself make a cash tender offer
for Company's shares.

                                       17
<PAGE>   18

     On September 1, 1999, the Chairman of the Daniel Green Company board of
directors, informed the board of Parent's decision. The board, with the Chairman
abstaining, made a determination that without the financial support of Parent it
would be unable to pursue the acquisition of the Company.

     On September 2, 1999 Parent informed the Company that Daniel Green Company
would no longer pursue the acquisition of the Company, and Parent sent its
expression of interest to make a cash tender offer at $11.75 per share, without
any financing contingency.

     The Board of Directors of the Company met on September 7, 1999 to consider
Parent's expression of interest and directed its officers to proceed to
negotiate terms and definitive agreements.

     From September 8, 1999 through October 6, 1999 the parties negotiated the
terms of the Merger Agreement.

     On October 1, 1999, Company's counsel notified Parent's counsel that
Company's Board met earlier that day and had authorized Company's counsel to
request that Parent increase its Offer price above $12 per Share.

     On October 3, 1999, Parent's counsel telephoned Company's counsel and
advised that Parent was unwilling to raise its Offer price above $11.75 per
Share. Counsel for both sides then negotiated open issues with respect to the
Merger Agreement.

     The Board of the Company approved the Offer and the Merger on October 6,
1999. The definitive agreements were signed by representatives of Parent and the
Company on October 6, 1999.

     The proposed transaction was publicly announced by the Company on the
morning of October 7, 1999. A copy is filed as an exhibit to the Schedule 14D-1
and is incorporated herein by reference.

     THE MERGER AGREEMENT.  The following is a summary of certain provisions of
the Merger Agreement, a copy of which is filed as an exhibit to the Schedule
14D-1. The summary is not a complete description of the terms and conditions of
the Merger Agreement and the summary is qualified in its entirety by reference
to the Merger Agreement.

     THE OFFER.  The Merger Agreement provides for the commencement of the Offer
as promptly as practicable (but in no event later than five business days after
the public announcement of the execution of the Merger Agreement). Purchaser has
commenced the Offer in accordance with the terms of the Merger Agreement.

     Subject to the terms of the Merger Agreement and subject to the prior
satisfaction or waiver of the conditions of the Offer (including, without
limitation, the Minimum Condition), the Merger Agreement requires Purchaser to
accept for payment and pay for, all Shares validly tendered and not withdrawn.
The obligation of Purchaser to accept for payment and pay for Shares validly
tendered and not withdrawn prior to the expiration of the Offer is subject to
the satisfaction of the Minimum Condition and certain other conditions that are
described in Section 13 -- "Certain Conditions of the Offer" hereof. Purchaser
and Parent have agreed that Purchaser will not amend or waive the Minimum
Condition to be less than 80% of the total issued and outstanding shares (other
than treasury shares) of Company Common Stock and will not decrease the Offer
Price, change the form of consideration to be paid, decrease the number of
Shares sought, amend the conditions to the Offer or impose conditions to the
Offer in addition to those set forth in Section 13 -- "Certain Conditions of the
Offer" hereof without the prior written consent of the Company.

     EXTENSION OF THE OFFER.  Purchaser is entitled to extend the Offer (and
defer the Expiration Date) for a period of up to 90 days from commencement of
the Offer, in one or more periods of not more than 10 business days each, if at
the initial expiration date of the Offer, or any extension thereof, any
condition to the Offer is not satisfied or waived ("Extension A"). Parent also
agrees that, subject to the terms and conditions of the Merger Agreement, to
cause Purchaser to extend the Offer in intervals of not less than five business
days each until December 31, 1999, provided that all conditions to the Offer
continue to be capable of being satisfied as of or prior to that date. Purchaser
also is entitled, but shall be under no obligation, to extend the Offer (and to
defer the Expiration Date) further for an additional period ending no more than
150 days (in one or more periods of not more than 10 business days each)
following an extension pursuant to Extension A, if at the

                                       18
<PAGE>   19

Expiration Date, as deferred pursuant to Extension A, the Litigation Condition
or the Trading Suspension Condition (as defined in Section 13 -- "Certain
Conditions to the Offer") have not been satisfied or waived. Further, Purchaser
is entitled to extend the Offer for any period required by any rule, regulation,
interpretation or provision of the Commission. Furthermore, at the Expiration
Date, if all conditions to the Offer have been satisfied or waived, and for so
long as less than 90% of the outstanding shares of Company Common Stock have
been validly tendered and not properly withdrawn pursuant to the Offer,
Purchaser may, in its sole discretion and without the consent of the Company,
extend the Offer (and defer the Expiration Date) for up to an additional 10
business days in the aggregate (in periods of no more than five business days
each). In addition, the Offer Price may be increased and the Offer may be
extended to the extent required by law in connection with such increase without
the consent of the Company. Any extension of the Offer in accordance therewith
shall defer the Expiration Date until the latest date to which the Offer is so
extended. During any such extension, all Shares previously tendered and not
withdrawn will remain tendered pursuant to the Offer, subject to the rights of a
tendering stockholder to withdraw his, her or its Shares. See Section 4 --
"Withdrawal Rights".

     BOARD REPRESENTATION; DIRECTORS.  The Merger Agreement provides that so
long as it is in effect, the Company will not cause or permit the size of the
Board to be expanded to more than five directors. The Merger Agreement also
provides that, promptly upon the purchase of and payment for Shares by Parent or
any of its subsidiaries if the Minimum Condition has been met, Parent will be
entitled to designate three directors for election to the Company's five member
Board. The Company will, upon request of and as specified by Purchaser or
Parent, secure the resignations of such number of its incumbent directors as is
necessary to enable Parent's designees to be so elected to the Board, and will
take all actions necessary to cause Parent's designees to be so elected or
appointed. At such times, the Company will use its reasonable best efforts to
cause individuals designated by Parent to constitute the same percentage as such
individuals represent on the Board, of each committee of the Board (other than
any committee of the Board established to take action under the Merger
Agreement). Notwithstanding the foregoing, until the Effective Time, the Company
will retain as members of its Board at least two directors who are directors of
the Company on the date of the Merger Agreement; provided, that after
satisfaction of Minimum Condition and subsequent to the purchase of and payment
for Shares pursuant to the Offer, Parent will always have its designees
represent at least a majority of the entire Board.

     From and after the time, if any, that Parent's designees constitute a
majority of the Board, until the Effective Time the unanimous vote of the entire
Board is required for the Company to: (i) amend or terminate the Merger
Agreement, (ii) extend the time for performance of any of the obligations of
Parent or Purchaser thereunder, or (iii) waive any condition or any of the
Company's obligations, rights or remedies thereunder.

     THE MERGER.  Following consummation of the Offer, upon the terms and
subject to the conditions of the Merger Agreement and in accordance with Maine
Law, at the Effective Time, Purchaser will be merged with and into the Company.
As a result of the Merger, the separate corporate existence of Purchaser will
cease and the Company will continue as the successor or surviving corporation
(the "Surviving Corporation") and will be an indirect wholly-owned subsidiary of
Parent. Hereinafter, the date on which the Closing of the Merger will take place
is referred to as the "Closing Date". The Merger will become effective at such
time as duly prepared articles of merger are filed with the Secretary of State
of the State of Maine in accordance with Maine Law or such other time as is
agreed upon by the parties and specified in the articles of merger (the
"Effective Time").

     The Merger Agreement provides that the directors of Purchaser immediately
prior to the Effective Time will be the initial directors of the Surviving
Corporation and that the officers of the Company immediately prior to the
Effective Time (other than the Chief Executive Officer) will be the initial
officers of the Surviving Corporation. The Merger Agreement also provides that,
at the Effective Time, the Articles of Incorporation and the By-Laws of the
Purchaser will be the Articles of Incorporation and the By-Laws of the Surviving
Corporation.

     CONVERSION OF SECURITIES.  Pursuant to the Merger Agreement, at the
Effective Time, each share of common stock, par value $.001 per share, of
Purchaser issued and outstanding immediately prior to the

                                       19
<PAGE>   20

Effective Time will be converted into and exchanged for one share of common
stock, par value $1.00 per share, of the Surviving Corporation. All Shares that
are owned by the Company as treasury stock will be canceled and retired and
cease to exist without payment of any consideration therefor. In addition, each
Share issued and outstanding immediately prior to the Effective Time (other than
Shares of Demanding Common Stock (as defined below), and Dissenting Common Stock
(as defined below) and Shares held by Parent or any of its wholly owned
subsidiaries, including Purchaser)) will be converted into the right to receive
the Offer Price payable to the holder thereof, without interest (the "Merger
Consideration"), upon surrender of the certificate formerly representing such
Shares. All such Shares, when so converted, will no longer be outstanding and
will automatically be canceled and retired and will cease to exist, and each
certificate evidencing such Shares shall cease to have any rights with respect
thereto, except the right to receive the Merger Consideration therefor upon its
surrender in accordance with this Offer to Purchase, without interest.

     Notwithstanding the above, neither Demanding Shares nor Dissenting Shares
will be converted into the right to receive the Merger Consideration, but
instead, holders of Demanding Shares or Dissenting Shares will be entitled only
to the rights granted by the provisions of Sections 910 or 909, respectively, of
Maine Law, which entitles stockholders exercising their rights thereunder to
receive a judicial determination of the fair value of their shares and to
receive payment of such fair value in cash, together with a fair rate of
interest, if any. Such judicially determined fair value could be more or less
than the Merger Consideration. See Section 14 -- "Certain Legal Matters and
Regulatory Approvals".

     STOCK OPTIONS.  As of the Effective Time, each person who holds an
outstanding employee stock option to purchase Shares (an "Option") granted under
the Company's 1991 Stock Option Plan (the "Option Plan"), will be entitled to
receive the product of (A) the excess, if any, of the Offer Price over the
exercise price of each such Option and (B) the number of Shares subject thereto
(such payment, if any, to be net of applicable withholding taxes) (the "Option
Price"). Prior to the consummation of the Offer, the holders of such Options may
either (i) exercise their Options and tender the Shares issued in connection
therewith or (ii) transfer their Options to Purchaser in consideration for an
amount equal to the Option Price for their Options. Effective upon the Company's
execution of the Merger Agreement, the Company may not make any further grants
under the Option Plan. As of the Effective Time the Option Plan will terminate
and all rights and obligations of the Company and the holder of any Option under
any provision of the Option Plan, any agreement entered into thereunder or any
other plan, program or arrangement providing for the issuance of grant of any
other interest in respect of the capital stock of the Company shall be canceled.
The Company will take all action necessary to ensure that, after the time of the
consummation of the Merger, no person shall have any right under the Option Plan
or any other plan, program or arrangement with respect to equity securities of
the Company.

     STOCKHOLDERS' APPROVAL.  Pursuant to the Merger Agreement, if required by
applicable law to consummate the Merger, the Company will (i) duly call, give
notice of, convene and hold a special meeting of its stockholders (the "Special
Meeting") as soon as practicable following the acceptance for payment and
purchase of Shares by Purchaser pursuant to the Offer for the purposes of
considering and taking action upon the Merger Agreement; (ii) prepare and file
with the SEC a preliminary proxy or information statement relating to the Merger
and the Merger Agreement and use its reasonable best efforts to obtain and
furnish the information required to be included by the SEC in the Proxy
Statement (as hereinafter defined) and, after consultation with Parent, to
respond promptly to any comments made by the SEC with respect to the preliminary
proxy or information statement and cause a definitive proxy or information
statement (the "Proxy Statement") to be mailed to its stockholders; (iii) use
its reasonable best efforts to obtain the necessary stockholder approval of the
Merger and Merger Agreement; and (iv) subject to the fiduciary obligations of
the Board under applicable law as advised by independent counsel, include in the
Proxy Statement the recommendation of the Board that stockholders of the Company
vote in favor of the approval of the Merger and the adoption of the Merger
Agreement.

     Parent shall vote, or cause to be voted, all the Shares then owned by it,
Purchaser or any of its other subsidiaries and affiliates in favor of the
approval of the Merger and the approval and adoption of the Merger Agreement.

                                       20
<PAGE>   21

     However, if Parent or Purchaser acquires at least 90% of the outstanding
Shares pursuant to the Offer or otherwise, each of the parties will take all
necessary and appropriate action to cause the Merger to become effective as soon
as practicable after such acquisition, without a meeting of stockholders of the
Company, in accordance with the "short-form" merger provisions of Section 904 of
Maine Law, if possible.

     REPRESENTATIONS AND WARRANTIES.  The Merger Agreement contains various
customary representations and warranties of the parties thereto, including

          (o) the Company shall not announce an intention, enter into any formal

     CONFIDENTIALITY AGREEMENT.  Unless otherwise required by law, Parent has
agreed to hold any information furnished to it by the Company which is
non-public in confidence in accordance with the provisions of the
Confidentiality Agreement between the Company and Parent dated as of September
21, 1999 (the "Confidentiality Agreement").

     NO SOLICITATION.  The Company has agreed that it will not, and will use its
best efforts to cause its respective officers, directors, employees and
investment bankers, attorneys or other agents retained by or acting on behalf of
the Company not to, (i) initiate, solicit or encourage (including by way of
furnishing non-public information), directly or indirectly, any inquiries or the
making of any proposal that constitutes or is reasonably likely to lead to any
Acquisition Proposal (as defined below), (ii) except as described below, engage
in negotiations or discussions with, or furnish any information or data to any
third party relating to an Acquisition Proposal or (iii) enter into any
agreement with respect to any Acquisition Proposal or approve any Acquisition
Proposal. The Company is also required to promptly request each person that has
executed a confidentiality agreement in connection with its consideration of an
Acquisition Proposal to return or destroy

                                       22
<PAGE>   23

all non-public information furnished to such person by or on behalf of the
Company. The Company is further required to, and to cause its directors,
officers, employees and financial advisors and other agents or representatives
to, cease immediately and cause to be terminated all activities, discussions or
negotiations, if any, with persons or entities being conducted with respect to
any Acquisition Proposal.

     The Company, the Board and the Company's officers, employees, accountants,
consultants, counsel, financing sources and other representatives (i) may
participate in discussions or negotiations (including, as a part thereof, making
any counterproposal) with or furnish information to any third party making an
unsolicited Acquisition Proposal (a "Potential Acquiror") if the Board
determines in good faith upon the advice of its independent legal counsel, that
the failure to participate in such discussions or negotiations or to furnish
such information would be inconsistent with its fiduciary duties under
applicable law, and (ii) will be permitted to take and disclose to the Company's
stockholders a position with respect to any tender or exchange offer by a third
party, or amend or withdraw such position, pursuant to Rules 14d-9 and 14e-2
under the Exchange Act, provided that the Board shall not recommend that the
stockholders of the Company tender their shares in connection with any such
tender or exchange offer unless the Board of the Directors of the Company
determines in good faith judgment, upon the advice of its independent legal
counsel, that failing to take such action would be inconsistent with the Board's
fiduciary duties under applicable law.

     Any non-public information furnished to a Potential Acquiror shall be
furnished pursuant to a confidentiality agreement substantially similar to the
confidentiality provisions of the Confidentiality Agreement. In the event that
the Company determines to provide any information as described above, or
receives any Acquisition Proposal, it will promptly inform Parent in writing as
to the fact that information is to be provided and will furnish to Parent the
identity of the recipient of such information or the Potential Acquiror and the
terms of such Acquisition Proposal. The Company is required to promptly provide
to Parent any non-public information concerning the Company provided to any
other person which has not been previously provided to Parent.

     The Board may not (i) withdraw or modify or propose to withdraw or modify,
in any manner adverse to Parent, its approval or recommendation of the Merger
Agreement, the Offer or the Merger, (ii) approve or recommend, or propose to
approve or recommend, any Acquisition Proposal or (iii) enter into any agreement
with respect to any Acquisition Proposal; notwithstanding the foregoing, the
Board may withdraw or modify or propose to withdraw or modify its recommendation
of the Merger Agreement, the Offer or the Merger recommend or propose to
recommend an Acquisition Proposal or terminate this the Merger Agreement
pursuant to Section 7.1(e) of the Merger Agreement and thereafter enter into an
agreement in connection with such Acquisition Proposal if, in each case, the
Board determines in good faith, upon the advice of its independent legal
counsel, that it would be inconsistent not to do so in order to comply with its
fiduciary duties to the Company's stockholders under applicable law. The Company
will provide at least five business days advance notice to Parent to the effect
that it is taking such action.

     "Acquisition Proposal" means any bona fide offer or proposal, whether in
writing or otherwise, made by a third party to acquire beneficial ownership of
all or a material portion of the assets of, or any material equity interest in,
the Company pursuant to a merger, consolidation or other business combination,
recapitalization, sale of shares of capital stock, sale of assets, tender offer
or exchange offer or similar transaction involving the Company (other than the
transactions contemplated by the Merger Agreement).

     DIRECTORS' AND OFFICERS' INSURANCE AND INDEMNIFICATION.  Parent has agreed
for a period of five (5) years, from and after the consummation of the Offer, to
cause the Surviving Corporation to indemnify, defend and hold harmless (and to
cause the Surviving Corporation to advance expenses as incurred to the fullest
extent permitted under applicable law if an appropriate undertaking is given to
the Surviving Corporation by the indemnified party) any person who is now, or
has been at any time prior to the Effective Time, an officer or director (the
"Indemnified Party") of the Company against all losses, claims, damages,
liabilities, costs and expenses (including attorneys' fees and expenses),
judgments, fines, losses and amounts paid in settlement in connection with any
actual or threatened action, suit, claim, proceeding or investigation (each a
"Claim") to the extent that any such Claim is based on, or arises out of, (i)
the fact that such person is or was a director or officer of the Company or is
or was serving at the request of the Company as a director or officer of another

                                       23
<PAGE>   24

corporation, partnership, joint venture, trust or other enterprise or (ii) the
Merger Agreement, or any of the transactions contemplated thereby, in each case
to the extent that any such Claim pertains to any matter or fact arising,
existing or occurring prior to or at the Effective Time, regardless of whether
such Claim is asserted or claimed prior to, at or after the Effective Time, to
the full extent provided in the Company's Articles of Incorporation or By-laws
in effect at the date of the Merger Agreement, subject to limitations imposed by
applicable law.

     In addition, for a period of five years after the Effective Time, Parent
will cause the Surviving Corporation to maintain in effect a policy of
directors' and officers' liability insurance with reputable and financially
sound carriers covering those persons who, as of immediately prior to the
Effective Time, are covered by the Company's policy, containing terms and
conditions which are no less advantageous to the insured parties than currently
provided by Company. However, Parent shall not be obligated to cause the
Surviving Corporation to make annual premium payments for such insurance in
excess of 150% of the annual premiums paid as of the date of the Merger
Agreement by the Company for such insurance (such amount, the "Maximum
Premium"). If such insurance coverage cannot be obtained at all, or can only be
obtained at an annual premium in excess of the Maximum Premium, Parent will
cause the Surviving Corporation to maintain the most advantageous policies of
directors' and officers' insurance obtainable for an annual premium equal to the
Maximum Premium. In addition, if such insurance coverage cannot be obtained at
all, Parent shall purchase all available run-off insurance policies with respect
to pre-existing insurance in an amount that, together with all other insurance
purchased pursuant to this paragraph, does not exceed the Maximum Premium.

     FEES AND EXPENSES.  All costs and expenses incurred in connection with the
Merger Agreement and the transactions contemplated thereby will be paid by the
party incurring such expenses.

     EMPLOYEE MATTERS.  Pursuant to the Merger Agreement, Purchaser will treat
service with the Company prior to the Effective Time by each employee of the
Company in the same manner as service with the Company is treated for
eligibility and vesting purposes (and excluding benefit accrual purposes,
including, without limitation, benefit service under any defined benefit pension
plan) under any benefit plan of Company in which any such employee is eligible
to participate following the Effective Time and which Purchaser elects in its
sole discretion to continue or as Purchaser otherwise deems appropriate for any
new benefits established by the Surviving Corporation for Company employees who
become employed by the Surviving Corporation. However, Purchaser shall not be
obligated to (i) make any particular benefit plan or benefit available to any
such employee, (ii) continue any particular benefit plan or benefit or (iii)
refrain from terminating or amending any particular benefit plan or benefit.

     CONDITIONS TO THE MERGER.  The respective obligation of each party to
effect the Merger are subject to the satisfaction on or prior to the Closing
Date of each of the following conditions:

          (a) STOCKHOLDER APPROVAL.  The Merger Agreement shall have been

     Company;

          (d) INJUNCTIONS.  There will be no order or injunction of a federal or
     state court or other governmental entity of competent jurisdiction in
     effect precluding, restraining, enjoining or prohibiting consummation of

     injunction, ruling or other action the parties to the Merger Agreement have
     used their respective reasonable best efforts to lift), in each case
     permanently restraining, enjoining or otherwise prohibiting the
     transactions contemplated in the Merger Agreement and such order, decree,
     injunction, ruling or other action shall have become final and non-
     appealable; provided that the party seeking to terminate the Merger

                                       25
<PAGE>   26

          (f) The Company, if on any Expiration Date on which no further rights
     to extend the Offer are available to, or have been exercised by, Purchaser,

     pay for Shares pursuant to the Offer, provided the Company has not breached
     in any material respect its obligations under the Merger Agreement that in
     any manner shall have proximately contributed in any material respect to
     such failure; or

          (g) Parent and Purchaser, if on any Expiration Date on which no

     payment and pay for shares pursuant to the Offer shall have been satisfied
     or waived other than the Minimum Condition and Purchaser terminates the
     Offer without purchasing Shares pursuant to the Offer; provided, however,
     that this right to terminate the Merger Agreement shall not be available to
     Parent and Purchaser if either of them has breached in any material respect
     its obligations under this Agreement in any manner that shall have
     proximately contributed in any material respect to the termination of the
     Offer.

     In the event of the termination of the Merger Agreement as provided above,
the Merger Agreement will become null and void, and there will be no liability

Merger Agreement relating to the Confidentiality Agreement and the payment of
the Termination Fee (as defined below) and (ii) nothing in the Merger Agreement
will relieve any party of liability for fraud or willful breach of the Merger
Agreement.

     Pursuant to the Merger Agreement, in the event that Company, Parent or
Purchaser terminates the Merger Agreement pursuant to paragraph (e) above, then
the Company will simultaneously with or prior to such termination, pay to Parent
by wire transfer of immediately available funds to an account designated by
Parent an amount equal to $1.5 million (the "Termination Fee"). If the Company
fails to promptly pay the Termination Fee, the Company will also pay Parent's
reasonable out-of-pocket costs and expenses incurred in connection with
litigation to obtain such payment. The Merger Agreement provides that payment of
the Termination Fee does not derogate from any rights or remedies which Parent
or Purchaser may possess under the Merger Agreement or applicable law, provided
that the Termination Fee will be liquidated damages and the sole and exclusive
remedy of Parent in the event that the Merger Agreement is terminated under
circumstances which entitle Parent to payment of such fee.

     THE TENDER AGREEMENTS.  The following is a summary of the Tender
Agreements, a copy of which is filed as an exhibit to the Schedule 14D-1. Such
summary is qualified in its entirety by reference to the Tender Agreements.

     Pursuant to the Tender Agreements and in order to induce Parent and
Purchaser to enter into the Merger Agreement, the Principal Stockholders, who
collectively hold 740,321.5 shares of Company Common Stock, representing
approximately 53.33% of the total issued and outstanding shares of Company
Common Stock on the date of the Tender Agreements, have agreed to tender or
cause the record owner thereof to tender all their Shares pursuant to the Offer
and not to withdraw any Shares tendered in the Offer.

     Parent and Purchaser agree (a) not to decrease the price to be paid to the
Company's stockholders in the Offer or the Merger below $11.75 per Share, and
that (b) on the date that the Shares are accepted for payment and purchased by
Purchaser pursuant to the Offer, Purchaser or Parent, as the case may be, shall
make, or cause to be made by the paying agent, to each Principal Stockholder the
purchase price for all its Shares that are tendered by it and accepted for
payment and purchased by Purchaser to such account as is designated by such
Principal Stockholder in a letter of transmittal which accompanies the tender of
the Shares.

     Each Principal Stockholder has agreed not to enter into any agreement,
arrangement or understanding with any person the effect of which would be
inconsistent or violative of the provisions and agreements described in the
Principal Stockholders' respective Tender Agreements.

     Except as provided above, until the termination of his Tender Agreement,
each Principal Stockholder has agreed not to, directly or indirectly, (i)
transfer to any entity any or all of its Shares held by it; or (ii) grant any

                                       26
<PAGE>   27

proxies or powers of attorney, deposit any of its Shares into a voting trust or
enter into a voting agreement, understanding or arrangement with respect to such
Shares.

     Each Principal Stockholder has also agreed, solely in its capacity as a
stockholder of the Company, that he or she will not, and will cause its agents
or representatives not to, directly or indirectly, (i) initiate, solicit or
encourage (including by way of furnishing non-public information) any inquiries
or the making of any proposal that constitutes or is reasonably likely to lead
to an Acquisition Proposal or (ii) engage in negotiations or discussions with,
or furnish any information or data to, any third party relating to an
Acquisition Proposal. In addition, the Principal Stockholders will promptly
inform Parent of the terms of any proposal, discussion, negotiation or inquiry
(and will disclose any written materials received by them in connection with
such proposal, discussion, negotiation or inquiry) and the identity of the party
making such proposal or inquiry, which the Principal Stockholders may receive in
respect of any Acquisition Proposal. Any action taken by the Company or any
member of the Board in his or its capacity as such in accordance with his
fiduciary duties under applicable law shall be deemed not to violate this
undertaking in the Tender Agreement.

     The Tender Agreements, and all rights and obligations of the parties
thereunder, will terminate upon the date upon which the Merger Agreement is
terminated in accordance with its terms.

11. PURPOSE OF THE OFFERING; PLANS FOR THE COMPANY AFTER THE OFFER AND THE
    MERGER.

     PURPOSE OF THE OFFER.  The purpose of the Offer and the Merger is for
Parent to acquire control of, and the entire equity interest in, the Company.
The purpose of the Merger is for Parent to acquire all Shares not purchased
pursuant to the Offer. Upon consummation of the Merger, the Company will be an
indirect wholly-owned subsidiary of Parent. The Offer is intended to increase
the likelihood that the Merger will be completed promptly.

     VOTE REQUIRED TO APPROVE MERGER.  Maine Law requires, among other things,
that the adoption of any plan of merger or consolidation of the Company must be
approved by the Board and by the holders of a majority of the outstanding
Shares, unless a corporation's charter or by-laws provides for a higher
percentage. The Company's By-Laws require the approval of 55% of the outstanding
Shares to consummate a merger. The Board has approved the Offer and the Merger;
in addition, under the Tender Agreements, the Principal Stockholders have agreed
to tender and sell all of their Shares pursuant to the Offer. Although the
Shares subject to the Tender Agreements constituted approximately 53.33% of all
issued and outstanding Shares as of the date of the Merger Agreement, they do
not constitute the 55% which Company By-Laws require for approval. Thus,
Purchaser will not have sufficient voting power to effect the Merger without the
vote of any other stockholder of the Company, which vote will be granted to
Purchaser by virtue of the tendered Shares which constitute the Minimum
Condition. Maine Law also provides that if a parent company owns at least 90% of
each class of stock of a subsidiary, the parent company can effect a "short
form" merger with that subsidiary without the action of the other stockholders
of the subsidiary. Accordingly, if, as a result of the Offer or otherwise, the
Offeror acquires or controls at least 90% of the outstanding Shares, Purchaser
may be able to effect the Merger without any action by, other stockholders of
the Company. Under this procedure, the Company is required by law to provide
notice of the Merger to stockholders.

     PLANS FOR THE COMPANY.  It is expected that, initially following the
Merger, the business and operations of the Company will, except as set forth in
this Offer to Purchase, be continued by the Company substantially as they are
currently being conducted. Parent will continue to evaluate the business and
operations of the Company after the consummation of the Offer and the Merger,
and will take such actions as it deems appropriate under the circumstances then
existing. Parent intends to seek additional information about the Company during
this period. Thereafter, Parent intends to review such information as part of a
comprehensive review of the Company's business, operations, capitalization and
management with a view to optimizing exploitation of the Company's potential.

     Parent also intends to explore with Daniel Green Company whether and on
what terms a combination of that entity with the Company is feasible. As was
stated above, Parent owns approximately 35.1% of the outstanding common stock of
Daniel Green. In any such investigation and/or negotiation, James Riedman,

                                       27
<PAGE>   28

President of Parent and Chairman and CEO of Daniel Green Company, would recuse
himself from deliberations of the Daniel Green Company Board.

     Except as indicated in this Offer to Purchase, Parent does not have any
present plans or proposals which relate to or would result in an extraordinary
corporate transaction, such as a merger, reorganization or liquidation,
involving the Company or any of its subsidiaries, a sale or transfer of a
material amount of assets of the Company or any of its subsidiaries, any
material change in the Company's capitalization or dividend policy or any other
material change in the Company's corporate structure or business.

12. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES, EXCHANGE LISTING AND
    EXCHANGE ACT REGISTRATION.

     The purchase of Shares by Purchaser pursuant to the Offer will reduce the
number of Shares that might otherwise trade publicly and will reduce the number
of holders of Shares, which could adversely affect the liquidity and market
value of the remaining Shares, if any, held by the public.

     If the Offer and Merger are consummated, the Shares will no longer meet the
requirements of the AMX for continued listing and will be delisted from the AMX.
According to the AMX's published guidelines, the AMX considers delisting the
Shares if, among other things, the number of record holders falls below 300, the
number of publicly held Shares (exclusive of holdings of officers, directors and
their immediate families and other concentrated holdings of ten percent or more
("AMX Excluded Holdings")) falls below 200,000 or the aggregate market value of
publicly held Shares (exclusive of AMX Excluded Holdings) falls below
$1,000,000. If, as a result of the purchase of Shares pursuant to the Offer or
otherwise, the Shares no longer meet the requirements of the AMX for continued
listing and the listing of the Shares is discontinued, the market for the Shares
could be adversely affected.

     If the AMX delists the Shares, it is possible that the Shares would
continue to trade on another securities exchange or in the over-the-counter
market and that price or other quotations would be reported by such exchange or
through the National Association of Securities Dealers Automated Quotation
System ("NASDAQ") or other sources. The extent of the public market therefor and
the availability of such quotations would depend, however, upon such factors as
the number of stockholders and/or the aggregate market value of the Shares
remaining at such time, the interest in maintaining a market in the Shares on
the part of securities firms, the possible termination of registration under the
Exchange Act as described below and other factors. Purchaser cannot predict
whether the reduction in the number of Shares that might otherwise trade
publicly would have an adverse or beneficial effect on the market price for or
marketability of the Shares or whether it would cause future market prices to be
greater or less than the Offer Price.

     The Shares are currently "margin securities", as such term is defined under
the rules of the Board of Governors of the Federal Reserve System (the "Federal
Reserve Board"), which has the effect, among other things, of allowing brokers
to extend credit on the collateral of the Shares. Depending upon factors similar
to those described above regarding the continued listing, public trading and
market quotations for the Shares, it is possible that, following the purchase of
the Shares pursuant to the Offer, the Shares will no longer constitute "margin
securities" for purposes of the margin regulations of the Federal Reserve Board,
in which event such Shares will no longer be used as collateral for loans made
by brokers.

     Registration of the Shares under the Exchange Act may be terminated upon
application of the Company to the Commission if the Shares are neither listed on
a national securities exchange nor held by 300 or more holders of record. The
termination of the registration of the Shares under the Exchange Act would
substantially reduce the information required to be furnished by the Company to
holders of Shares and to the Commission and would make certain provisions of the
Exchange Act, such as the short-swing profit recovery provisions of Section
16(b), the requirement of furnishing a proxy statement in connection with
stockholders' meetings and the requirements of Rule 13e-3 under the Exchange Act
with respect to "going private" transactions, no longer applicable to the
Shares. In addition, "affiliates" of the Company and persons holding "restricted
securities" of the Company may be deprived of the ability to dispose of their
Shares pursuant to Rule 144 promulgated under the Securities Act of 1933, as
amended. If registration of the Shares under the Exchange Act is terminated, the
Shares will no longer be "margin securities" or be eligible for stock exchange
listing or NASDAQ reporting. Purchaser currently intends to seek to cause the
Company to terminate the
                                       28
<PAGE>   29

registration of the Shares under the Exchange Act as soon after consummation of
the Offer as the requirements for termination of registration are met. If
registration of the Shares under the Exchange Act is not terminated prior to the
Merger becoming effective, registration of the Shares under the Exchange Act
will be terminated following consummation of the Merger.

13. CERTAIN CONDITIONS OF THE OFFER

     Notwithstanding any other provision of the Offer (subject to the provisions
of the Merger Agreement), Purchaser will not be required to accept for payment

or return tendered Shares promptly after termination or withdrawal of the
Offer), pay for, and may delay the acceptance for payment of or, subject to the
restriction referred to above, the payment for, any tendered Shares, and may

        Parent, the Purchaser or any other affiliate of the Parent, the purchase

        Subsidiaries, or to compel the Company, the Parent or any of their
        Subsidiaries to dispose of or hold separate all or any material portion
        of the business or assets of the Company, the Parent or any of their
        Subsidiaries, as a result of the Transactions; (C) seeking to impose or

        vote any Shares acquired by the Purchaser pursuant to the Offer, the

        the Merger Agreement or of the Principal Stockholders in the Tender
        Agreements shall not be true and correct in any respect, disregarding
        for this purpose any standard of materiality contained in any such
        representation or warranty, as of the date of consummation of the Offer
        as though made on or as of such date, except (i) for changes
        specifically permitted by the Agreement or (ii) (A) those
        representations and warranties that address matters only as of a
        particular date which are true and correct as of such date or (B) where
        the failure of such representations and warranties to be true and
        correct, do not, individually or in the aggregate, have a Company
        Material Adverse Effect.

             (iii) there shall have occurred, since June 30, 1999, any change,
        condition, event or development that, individually or in the aggregate

        could be reasonably expected to have, a Company Material Adverse Effect
        or any legal or regulatory changes that are or are reasonably expected
        to be materially adverse to the business operations, properties,
        condition (financial or otherwise), assets, liabilities (contingent or

                                       29
<PAGE>   30

        otherwise) or results of operation or prospects of the Company either

             (iv) the Company shall have breached or failed in any material
        respect to perform or comply with any material obligation, agreement or
        covenant required by the Merger Agreement to be performed or complied
        with by it (including, without limitation, if the Company shall have
        entered into any definitive agreement or any agreement in principle with
        any Person relating to an Acquisition Proposal (other than Parent,
        Purchaser or any affiliate thereof));

             (v) there shall have occurred (A) any general suspension of trading
        in, or limitation on prices for, securities on the American Stock
        Exchange, which suspension or limitation shall have continued for a

        or any suspension of payments in respect of banks in the United States
        or any limitation (whether or not mandatory) by Federal, state or
        foreign authorities on the extension of credit by lending institutions,
        which moratorium, suspension, or limitation in Parent's reasonable
        judgment is reasonably likely to materially affect the ability of Parent
        to pay for the Shares, (C) a commencement of a war or armed hostilities
        or other national or international calamity directly or indirectly
        involving the United States and reasonably likely to have a Company
        Material Adverse Effect or materially and adversely affect the
        consummation of the Offer, or (D) in the case of clauses (A), (B) and
        (C) above existing at the time of the commencement of the Offer, a
        material acceleration or worsening thereof (the "Trading Suspension
        Condition");

             (vi) the Board of Directors of the Company (or a special committee
        thereof) shall have withdrawn or amended, or modified in a manner
        adverse to Parent and Purchaser its recommendation of the Offer or the
        Merger, or shall have endorsed, approved or recommended any Acquisition
        Proposal other than the Transactions or failed to reconfirm its
        recommendation of this Agreement and the Transactions contemplated
        hereunder within five business days after being requested to do so by
        Parent and Purchaser;

             (vii) any Person, other than Parent, Purchaser or their affiliates
        or any group of which any of them is a member, acquires beneficial

        acquire 20% or more of the outstanding Shares of Common Stock;

             (viii) the Merger Agreement shall have been terminated in
        accordance with its terms; or

             (ix) the Parent, Purchaser and the Company shall have agreed in
        writing that the Purchaser shall terminate the Offer.

     The foregoing conditions are for the sole benefit of Purchaser and Parent
and, subject to the Merger Agreement, may be asserted by either of them or may
be waived by Parent or Purchaser, in whole or in part at any time and from time
to time in the sole discretion of Parent or Purchaser, provided that the Minimum
Condition may not be waived to be less than 80% of the total issued and
outstanding shares of Company Common Stock, without the Company's prior written
consent.

14. CERTAIN LEGAL MATTERS AND REGULATORY APPROVALS

     GENERAL.  Based upon its examination of publicly available information with
respect to the Company, the review of certain information furnished by the
Company to Parent and discussions of representatives of Parent with
representatives of the Company during Parent's investigation of the Company (see
Section 10), neither Purchaser nor Parent is aware of any license or other
regulatory permit that appears to be material to the business of the Company
which might be adversely affected by the acquisition of Shares by Purchaser
pursuant to the Offer or of any approval or other action by any domestic
(federal or state) or foreign governmental, administrative or regulatory
authority or agency which would be required prior to the acquisition of Shares
by Purchaser pursuant to the Offer. Should any such approval or other action be
required, it is Purchaser's present intention to seek such approval or action.
There can be no assurance that any such approval or other action, if needed,
would be obtained without substantial conditions or that adverse consequences
might not result to the business of the Company, Purchaser or Parent or that
certain parts of the
                                       30
<PAGE>   31

businesses of the Company, Purchaser or Parent might not have to be disposed of
or held separate or other substantial conditions complied with in order to
obtain such approval or other action or in the event that such approval was not
obtained or such other action was not taken. Purchaser's obligation under the
Offer to accept for payment and pay for Shares is subject to certain conditions,
including conditions relating to the legal matters discussed in this Section 14.
See Section 13 -- "Certain Conditions of the Offer".

     SECTION 611-A OF THE MAINE LAW.  The Company is incorporated under the laws
of the State of Maine. In general, Section 611-A of Maine Law ("Section 611-A")
prevents an "interested stockholder" (generally a person who owns or has the
right to acquire 25% or more of a corporation's outstanding voting stock or an
affiliate or associate thereof) from engaging in a "business combination"
(defined to include mergers and certain other transactions) with a Maine
corporation for a period of five years following the date such person became an
interested stockholder unless, among other things, prior to such date the board
of directors of the corporation approved either the business combination or
following the transaction in which the interested stockholder became an
interested stockholder, the business combination is approved by the board of
directors of the corporation and authorized at a meeting of shareholders by the
affirmative vote of the holders of a majority of the outstanding voting stock of
the corporation not owned by the interested shareholder. Neither Parent nor
Purchaser is an interested stockholder and the Company's Board of Directors has
approved both the Offer and the Merger. Accordingly, Section 611-A is
inapplicable to the Offer and the Merger.

     SECTION 910 OF MAINE LAW.  Except in the case of corporations whose
articles of incorporation specify otherwise, Section 910 of Maine Law ("Section
910") entitles shareholders to payment from a "Controlling Person" for his
shares upon the occurrence of a "Control Transaction", defined as the
acquisition by the controlling person of (i) voting power over voting shares
that carry with them the right to cast at least 25% of the votes that all
shareholders would be entitled to cast in an election of the directors of the
corporation or (ii) voting power over at least 25% of the shares in any class
entitled to elect all the directors of any specified number of them. A person
has voting power over a voting share if that person has or shares, directly or
indirectly, through any option, contract, arrangement, understanding, voting
trust, conversion right or relationship, or by acting jointly or in concert or
otherwise, the power to vote, or to direct the voting of, that voting share.

     Within fifteen (15) days of the Control Transaction, the Controlling Person
must give notice that a Control Transaction has occurred to each shareholder of
record of the corporation holding voting shares. Any holder of voting shares
may, prior to or within thirty (30) days after such notice has been given,
demand in writing that the Controlling Person pay such shareholder in cash an
amount equal to the "fair value" (defined as an amount which takes into
consideration all relevant factors, including an increment representing a
proportion of any value payable for acquisition of control of the corporation)
of each voting share held by the demanding shareholder.

     Within ten (10) days after the expiration of the period provided for making
such demand, the Controlling Person must make a written offer to each demanding
shareholder to pay for the shares at a specified price deemed by the Controlling
Person to be the fair value of those shares. The offer must be made at the same
price per share to each demanding shareholder of the same class.

     If any demanding shareholder and the Controlling Person agree upon the fair
value of the shares within thirty (30) days of the expiration of the demand
period, then the Controlling Person must pay the demanding shareholders within
ninety (90) days after the date on which the Controlling Person's offer to
purchase was made. If, however, one or more demanding shareholders fail to agree
with the Controlling Person within this thirty (30) day period as to the fair
value of the shares, (i) the Controlling Person may bring an action in Superior
Court in the County where the corporation's registered office is located or the
demanding shareholder may bring such suit in the name of the Controlling Person
if the Controlling Shareholder fails to institute such an action. In either
case, all demanding shareholders, except those who have previously agreed with
the Controlling Person on the fair value of the shares, shall be made parties to
the proceedings. The shareholder shall bear the burden of proving he is entitled
to receive payment. The Court shall fix the fair value of the shares. The
shareholders who are parties to the proceeding (except those determined by the
Court not to be entitled to receive payment) shall be entitled to judgment
against the Controlling Person for the fair value of

                                       31
<PAGE>   32

their shares, plus interest from the time of the Control Transaction and costs
and expenses (except, with respect to costs and expenses, in cases where the
Court finds that the shareholders' failure to accept the offer was in bad
faith).

     Section 910 does not apply if (i) the corporation does not have a class of
voting shares (x) registered or traded on a national securities exchange or (y)
registered with the Commission pursuant to the Exchange Act; or (ii) the
Controlling Person acquires such status inadvertently and divests itself of a
sufficient amount of its voting shares so that it is no longer a Controlling
Person as a soon as practicable, but in no event more than 30 days after the
Controlling Person receives notice from the corporation that it has become a
Controlling Person.

     Upon consummation of the Offer, Purchaser shall be deemed a "Controlling
Person" under Section 910 and a "control transaction" shall have occurred. As a
result, holders of Shares which are not tendered and purchased shall have the
right to demand that Purchaser pay the fair value of those Shares in cash.

     If any holder of Shares who demands payment under Section 910 fails to
perfect, or effectively withdraws or loses his right of payment as provided in
Maine Law, the Shares of such stockholder will be converted into the right to
receive the Merger Consideration in accordance with the Merger Agreement.

     A stockholder seeking to exercise rights under Section 910 may not tender
his Shares in the Offer. FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 910
(SEE SCHEDULE II ATTACHED HERETO) FOR PERFECTING PAYMENT RIGHTS MAY RESULT IN
LOSS OF SUCH RIGHTS.

     STATE TAKEOVER LAWS.  A number of other states have adopted laws and
regulations applicable to attempts to acquire securities of corporations that
are incorporated, or have substantial assets, stockholders, principal executive
offices or principal places of business, or whose business operations otherwise
have substantial economic effects, in such states. In Edgar v. Mite Corp., the
Supreme Court of the United States invalidated on constitutional grounds the
Illinois Business Takeover Statute, which, as a matter of state securities law,
made takeovers of corporations meeting certain requirements more difficult.
However, in 1987, in CTS Corp. v. Dynamics Corp. of America, the Supreme Court
held that the State of Indiana may, as a matter of corporate law and, in
particular, with respect to those aspects of corporate law concerning corporate
governance, constitutionally disqualify a potential acquiror from voting on the
affairs of a target corporation without the prior approval of the remaining
stockholders, provided that such laws were applicable only under certain
conditions. Subsequently, in TLX Acquisition Corp. v. Telex Corp., a Federal
district court in Oklahoma ruled that the Oklahoma statutes were
unconstitutional insofar as they applied to corporations incorporated outside
Oklahoma, in that they would subject such corporations to inconsistent
regulations. Similarly, in Tyson Foods, Inc. v. McReynolds, a Federal district
court in Tennessee ruled that four Tennessee takeover statutes were
unconstitutional as applied to corporations incorporated outside Tennessee. This
decision was affirmed by the United States Court of Appeals for the Sixth
Circuit. In December 1988, a federal district court in Florida held in Grand
Metropolitan PLC v. Butterworth that the provisions of the Florida Affiliated
Transactions Act and Florida Control Share Acquisition Act were unconstitutional
as applied to corporations incorporated outside of Florida.

     Based on information supplied by the Company, Parent and Purchaser do not
believe that any state takeover statutes (other than Section 611-A and Section
910) apply to the Offer or the Merger. Parent and Purchaser have not attempted
to comply with any state takeover laws. Should any person seek to apply any
state takeover law or claim that Parent or Purchaser have not properly complied
with any such law, Parent and Purchaser reserve the right to challenge the
validity or applicability of any such law allegedly applicable to the Offer or
the claim that it has not properly complied with any such law, in appropriate
court proceedings or otherwise, and nothing contained in this Offer to Purchase
nor any action taken in connection herewith is intended as a waiver of that
right. In the event it is asserted that one or more state takeover laws applies
to the Offer or the Merger or that Parent and Purchaser has not properly
complied with any such law, and an appropriate court does not determine that it
is inapplicable or invalid as applied to the Offer or the Merger or that Parent
or Purchaser has not properly complied with it, as the case may be. Parent
and/or Purchaser might be required to file certain information with, or receive
approvals from, the relevant state authorities. In addition, if enjoined,
Purchaser might be unable to accept for payment any Shares tendered pursuant to
the
                                       32
<PAGE>   33

Offer or be delayed in continuing or consummating the Offer and the Merger. In
such case, Purchaser may not be obligated to accept for payment, or pay for, any
Shares tendered. See Section 13 -- "Certain Conditions of the Offer".

     ANTITRUST.  Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended, and the rules that have been promulgated thereunder by the Federal
Trade Commission (the "FTC"), certain acquisition transactions may not be
consummated unless certain information has been furnished to the Antitrust
Division of the Department of Justice and the FTC and certain waiting period
requirements have been satisfied. Based on information supplied by the Company,
Parent and Purchaser believe that the acquisition of Shares by Purchaser
pursuant to the Offer and the Merger are not subject to such requirements.

     DISSENTERS' RIGHTS.  Holders of Shares do not have dissenters' rights as a
result of the Offer. However, if the Merger is consummated, holders of Shares
who have neither voted in favor of the Merger nor consented thereto in writing
may have rights pursuant to the provisions of Section 909 to dissent and demand
appraisal of, and to receive payment in cash of the fair value of, their Shares
as of the date prior to the Effective Date. If the statutory procedures
specified in Section 909 are complied with, such rights could lead to a judicial
determination of the fair value required to be paid in cash to such dissenting
holders for their Dissenting Shares. Any such judicial determination of the fair
value of the Dissenting Shares could be based upon considerations other than, or
in addition to, the Offer Price, the market value of the Dissenting Shares,
including asset values, and the investment value of the Dissenting Shares. The
value so determined could be greater or lower than the Offer Price.

     The procedure for exercising dissenter's rights is set forth in full in the
copy of Section 909 attached hereto as Schedule III.

     If any holder of Shares who demands appraisal under Section 909 fails to
perfect, or effectively withdraws or loses his right to appraisal, as provided
in Maine Law, the Shares of such stockholder will be converted into the right to
receive the Merger Consideration in accordance with the Merger Agreement. A
stockholder may withdraw his demand for appraisal by delivery to Parent of a
written withdrawal of his demand for appraisal and acceptance of the terms of
the Merger.

     A stockholder seeking to exercise dissenters' rights under Section 909 may
not tender his Shares in the Offer. FAILURE TO FOLLOW THE STEPS REQUIRED BY
SECTION 909 FOR PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE LOSS OF SUCH
RIGHTS.

     GOING PRIVATE TRANSACTIONS.  The Commission has adopted Rule 13e-3 under
the Exchange Act which is applicable to certain "going private" transactions and
which may under certain circumstances be applicable to the Merger or another
business combination following the purchase of Shares pursuant to the Offer in
which Purchaser seeks to acquire any remaining Shares not held by it. However,
Rule 13e-3 will not be applicable to the Merger or any such other business
combination if (i) the Shares are deregistered under the Exchange Act prior to
the Merger or other business combination, or (ii) the Merger or other business
combination is consummated within one year after the purchase of the Shares
pursuant to the Offer and the value of the consideration paid per Share in the
Merger or other business combination (measured at the time of consummation of
the Merger) is at least equal to the amount paid per Share in the Offer. If
applicable, Rule 13e-3 requires, among other things, that certain financial
information concerning the Company and certain information relating to the
fairness of the proposed transaction and the consideration offered to minority
stockholders in such transaction be filed with the Commission and disclosed to
stockholders prior to consummation of the transaction.

     MARGIN CREDIT REGULATIONS.  Federal Reserve Board Regulations T, U and X
(the "Margin Credit Regulations") restrict the extension or maintenance of
credit for the purpose of buying or carrying margin stock, including the Shares,
if the credit is secured directly or indirectly thereby. Such secured credit may
not be extended or maintained in an amount that exceeds the maximum loan value
of the margin stock. Under the Margin Credit Regulations, the Shares are
presently margin stock and the maximum loan value thereof is generally 50% of
their current market value. The definition of "indirectly secured" contained in
the Margin

                                       33
<PAGE>   34

Credit Regulations provides that the term does not include an arrangement with a
customer if the lender in good faith has not relied upon margin stock as
collateral in extending or maintaining the particular credit.

15. FEES AND EXPENSES

     Except as set forth below, Purchaser will not pay any fees or commissions
to any broker, dealer or other person for soliciting tenders of Shares pursuant
to the Offer.

     Purchaser and Parent have retained Georgeson Shareholder Communications
Inc., as the Information Agent, and EquiServe, L.P. as the Depository, in
connection with the Offer. The Information Agent may contact holders of Shares
by mail, telephone, telex, telecopy, telegraph and personal interview and may
request banks, brokers, dealers and other nominee stockholders to forward
materials relating to the Offer to beneficial owners.

     The Information Agent and the Depository will receive reasonable and
customary compensation for their services in connection with the Offer, plus
reimbursement for their reasonable out-of-pocket expenses, and will be
indemnified against certain liabilities in connection with the Offer, including
certain liabilities under the federal securities laws. Brokers, dealers,
commercial banks and trust companies will be reimbursed by Purchaser for
customary handling and mailing expenses incurred by them in forwarding material
to their customers.

16. MISCELLANEOUS

     Purchaser is not aware of any jurisdiction where the making of the Offer is
prohibited by any administrative or judicial action pursuant to any valid state
statute. If Purchaser becomes aware of any valid state statute prohibiting the
making of the Offer or the acceptance of Shares pursuant thereto, Purchaser will
make a good faith effort to comply with any such state statute. If, after such
good faith effort, Purchaser cannot comply with any such state statute, the
Offer will not be made to (nor will tenders be accepted from or on behalf of)
the holders of Shares in such state. In any jurisdiction where the securities,
blue sky or other laws require the Offer to be made by a licensed broker or
dealer, the Offer will be deemed to be made on behalf of Purchaser by one or
more registered brokers or dealers licensed under the laws of such jurisdiction.

     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF PURCHASER OR THE COMPANY NOT CONTAINED IN THIS OFFER

                         MAINE BUSINESS CORPORATION ACT

13A SEC. 910. RIGHT OF SHAREHOLDERS TO RECEIVE PAYMENT FOR SHARES FOLLOWING A
              CONTROL TRANSACTION

     1. SHAREHOLDERS ENTITLED TO RIGHTS; EXCEPTIONS.  Any holder of the voting
shares of a corporation that becomes the subject of a control transaction
described in subsection 2 shall be entitled to the rights and remedies provided
in this section, unless:

          A. The bylaws, by amendment adopted within 90 days of the effective
     date of this Act and not subsequently rescinded by an amendment of the

          B. The articles of incorporation provide that this section shall not
     be applicable to the corporation. [1985, c. 394, sec. 3 (new).]

     [1985, c. 394, sec. 3 (new).]

     2. DEFINITIONS.  As used in this section, unless the context indicates
otherwise, the following terms have the following meanings.

          A. A "controlling person" means:

             (1) A person who has, or a group of persons acting in concert that
        has, voting power over voting shares of the corporation that would
        entitle the holders of those shares to cast at least 25% of the votes
        that all shareholders would be entitled to cast in an election of the
        directors of the corporation; or

             (2) A person who has, or a group of persons acting in concert that
        has, voting power over at least 25% of the shares in any class of shares
        entitled to elect all the directors, or any specified number of them.

     A "person" includes any individual, firm, corporation or other entity.
[1985, c. 394, sec. 3 (new).]

          B. Notwithstanding paragraph A, a person or group of persons which
     would otherwise be a controlling person within the meaning of this section
     shall not be deemed a controlling person unless, subsequent to the
     effective date of this section, that person or group increases the
     percentage of outstanding voting shares of the corporation over which it
     has voting power to a percentage in excess of the percentage of outstanding
     voting shares of the corporation over which that person or group had voting
     power on the effective date of this section, and to at least the amount
     specified in paragraph A. [1985, c. 394, sec. 3 (new).]

          C. For the purposes of this section:

             (1) A person is not a controlling person under paragraph A if that
        person holds voting power, in good faith and not for the purpose of
        circumventing this section, as an agent, bank, broker, nominee or
        trustee for one or more beneficial owners who do not individually or, if
        they are a group acting in concert, as a group have the voting power
        specified in paragraph A or who are not considered a controlling person
        under paragraph B;

             (2) A person has voting power over a voting share if that person
        has or shares, directly or indirectly, through any option, contract,
        arrangement, understanding, voting trust, conversion right or
        relationship, or by acting jointly or in concert or otherwise, the power
        to vote, or to direct the voting of, that voting share; and

             (3) A person engaged in business as an underwriter or group
        consisting of persons engaged in business as underwriters is not a
        controlling person under paragraph A if that person or group holds
        voting power specified in paragraph A, in good faith and not for the
        purpose of circumventing this

                                      II-1
<PAGE>   37

        section, over shares of the corporation acquired through participation
        in good faith in a firm commitment underwriting of an offering of shares
        registered under the United States Securities Act of 1933. [1993, c.
        302, sec. 1 (amd).]

          D. A "control transaction" means the acquisition by a person or group
     of the status of a controlling person. [1985, c. 394, sec. 3 (new).]

          E. The "control transaction date" means the date on which a
     controlling person becomes a controlling person. [1985, c. 394, sec. 3
     (new).]

     [1993, c. 302, sec. 1 (amd).]

     3. NOTICE OF CONTROL TRANSACTION TO BE GIVEN TO SHAREHOLDERS.  Within 15
days of the control transaction date, notice that a control transaction has
occurred shall be given by the controlling person to each shareholder of record
of the corporation holding voting shares. If the controlling person so requests,
the corporation shall, at the option of the corporation and at the expense of
the controlling person, either furnish a list of all such shareholders to the
person or group or mail the notice to all such shareholders. There shall be
included in, or enclosed with, the notice a copy of this section. Any list
provided by the corporation to a controlling person pursuant to this subsection
shall be used only for the purpose of giving the notice required by this
subsection.

     [1985, c. 394, sec. 3 (new).]

     4. SHAREHOLDER DEMAND FOR PAYMENT.  After the control transaction date, any
holder of voting shares of the corporation may, prior to or within 30 days after
the notice required by subsection 3 is given, which time period shall be
specified in the notice, make written demand on the controlling person for
payment of the amount provided in subsection 5 with respect to the voting shares
of the corporation held by the shareholder, and the controlling person shall pay
that amount to the shareholder. The demand of the shareholder shall state the
number and class or series, if any, of the shares owned by him with respect to
which the demand is made.

     [1985, c. 394, sec. 3 (new).]

     5. SHAREHOLDER ENTITLED TO RECEIVE PAYMENT FOR SHARES.  A shareholder
making written demand under subsection 4 shall be entitled to receive cash for
each of his shares in an amount equal to the fair value of each voting share as
of the day prior to the control transaction date, taking into account all
relevant factors, including an increment representing a proportion of any value
payable for acquisition of control of the corporation.

     [1985, c. 394, sec. 3 (new).]

     6. SUBMISSION OF CERTIFICATES; NOTATION.  At the time of filing his demand
for payment for his shares pursuant to subsection 4, or within 20 days
thereafter, each shareholder demanding payment shall submit the certificate or
certificates representing his shares to the corporation or its transfer agent
for notation thereon that such demand has been made; such certificates shall
promptly be returned after entry thereon of such notation. A shareholder's
failure to do so shall, at the option of the controlling person, terminate his
rights under this section, unless a court of competent jurisdiction, for good
and sufficient cause shown, shall otherwise direct. If shares represented by a
certificate on which notation has been so made shall be transferred, each new
certificate issued for those shares shall bear a similar notation, together with
the name of the original holder of the shares who made the written demand, and a
transferee of the shares shall acquire by the transfer no rights in the
corporation other than those which the original demanding shareholder had after
making demand for payment of the fair value of the shares.

     [1985, c. 394, sec. 3 (new).]

     7. WRITTEN OFFER; BALANCE SHEET.  Within 10 days after the expiration of
the period provided in subsection 4 for making demand, the controlling person
shall make a written offer to each demanding shareholder to pay for those shares
at a specified price deemed by the controlling person to be the fair value of
those shares. The offer shall be made at the same price per share to all
demanding shareholders of the same class. The notice and offer shall be
accompanied by a balance sheet of the corporation as of the latest available

                                      II-2
<PAGE>   38

date and not more than 12 months prior to the making of the offer, and a profit
and loss statement of the corporation for the 12 months' period ended on the
date of the balance sheet.

     [1985, c. 394, sec. 3 (new).]

     8. AGREEMENT ON FAIR VALUE; PAYMENT.  If, within 30 days after the
expiration of the period provided in subsection 4 for making demand, the fair
value of the shares is agreed upon between any demanding shareholder and the
controlling person, payment for those shares shall be made within 90 days after
the date on which the written offer required by subsection 7 was made, upon
surrender of the certificate or certificates representing those shares. Upon
payment of the agreed value, the demanding shareholder shall cease to have any
interest in the shares.

     [1985, c. 394, sec. 3 (new).]

     9. FAILURE TO REACH AGREEMENT ON FAIR VALUE OF SHARES.  If, within the
additional 30-day period prescribed by subsection 8, one or more demanding
shareholders and the controlling person have failed to agree as to the fair
value of shares:

          A. The controlling person may, or shall, if it receives a demand as
     provided in subparagraph (1), bring an action in the Superior Court in the
     county in this State where the registered office of the corporation is
     located praying that the fair value of those shares be found and
     determined. This action:

             (1) Shall be brought by the controlling person, if it receives a
        written demand for suit from any demanding shareholder, which demand is
        made within 60 days after the date on which the written offer required
        by subsection 7 was made; and if it receives a demand for suit, the
        controlling person shall bring the action within 30 days after receipt
        of the written demand; or

             (2) In the absence of a demand for suit, may at the election of the
        controlling person be brought by the controlling person at any time from
        the expiration of the additional 30-day period prescribed by subsection
        8 until the expiration of 60 days after the date on which the written
        offer required by subsection 7 was made; [1985, c. 394, sec. 3 (new).]

          B. If the controlling person fails to institute the action within the
     period specified in paragraph A, any demanding shareholder may thereafter
     bring such an action in the name of the controlling person; [1985, c. 394,
     sec. 3 (new).]

          C. No such action may be brought, either by the controlling person or
     by a demanding shareholder, more than 6 months after the date on which the
     written offer required by subsection 7 was made; [1985, c. 394, sec. 3
     (new).]

          D. In any such action, whether initiated by the controlling person or
     by a demanding shareholder, all demanding shareholders, wherever residing,
     except those who have agreed with the controlling person upon the price to
     pay for their shares, shall be made parties to the proceeding as an action
     against their shares quasi in rem. A copy of the complaint shall be served
     on each demanding shareholder who is a resident of this State as in other
     civil actions, and shall be served by registered or certified mail, or by
     personal service without the State, on each demanding shareholder who is a
     nonresident. The jurisdiction of the court shall be plenary and exclusive;
     [1985, c. 394, sec. 3 (new).]

          E. The court shall determine whether each demanding shareholder, as to
     whom the controlling person requests the court to make such determination,
     has satisfied the requirements of this section and is entitled to receive
     payment for his shares; as to any demanding shareholder with respect to
     whom the controlling person makes such a request, the burden is on the
     shareholder to prove that he is entitled to receive payment. The court
     shall then proceed to fix the fair value of the shares. The court may, if
     it so elects, appoint one or more persons as appraisers to receive evidence
     and recommend a decision on the question of fair value. The appraisers
     shall have such power and authority as shall be specified in the order of
     their appointment or an amendment to the order of appointment; [1985, c.
     394, sec. 3 (new).]

          F. All shareholders who are parties to the proceedings shall be
     entitled to judgment against the controlling person for the amount of the
     fair value of their shares, except for any shareholder whom the
                                      II-3
<PAGE>   39

     court shall have determined not to be entitled to receive payment for his
     shares. The judgment shall be payable only upon and concurrently with the
     surrender to the controlling person of the certificate or certificates
     representing those shares. Upon payment of the judgment, the demanding
     shareholder shall cease to have any interest in those shares; [1985, c.
     394, sec. 3 (new).]

          G. The judgment shall include an allowance for interest at such rate
     as the court may find to be fair and equitable in all the circumstances,
     from the control transaction date to the date of payment. If the court
     finds that the refusal of any shareholder to accept the controlling
     person's offer of payment for his shares was arbitrary, vexatious or not in
     good faith, it may in its discretion refuse to allow interest to him;
     [1985, c. 394, sec. 3 (new).]

          H. The costs and expenses of any such proceeding shall be determined
     by the court and shall be assessed against the controlling person, but all
     or any part of those costs and expenses may be apportioned and assessed as
     the court may deem equitable against any or all of the demanding
     shareholders who are parties to the proceeding to whom the controlling
     person shall have made an offer to pay for the shares, if the court finds
     that the action of those shareholders in failing to accept that offer was
     arbitrary or vexatious or not in good faith. Those expenses shall include
     reasonable compensation for and reasonable expenses of the appraisers, but
     shall exclude the fees and expenses of counsel for any party and shall
     exclude the fees and expenses of experts employed by any party, unless the
     court otherwise orders for good cause. The court shall award each
     shareholder who is a party to the proceeding reasonable compensation for
     any expert or experts employed by the shareholder in the proceeding and the
     shareholder's reasonable attorney's fees and expenses, if:

             (1) No offer was made; or

             (2) The fair value of the shares as determined materially exceeds
        the amount which the controlling person offered to pay therefor; and
        [1985, c. 728 (amd).]

          I. At all times during the pendency of any such proceeding, the court
     may make any and all orders which may be necessary to protect the
     corporation, the controlling person or the demanding shareholders, or which
     are otherwise just and equitable. Those orders may include, without
     limitation, orders:

             (1) Requiring the controlling person to pay into court, or post
        security for, the amount of the judgment or its estimated amount, either
        before final judgment or pending appeal;

             (2) Requiring the deposit with the court of certificates
        representing shares held by the demanding shareholders;

             (3) Imposing a lien on the property of the controlling person to
        secure the payment of the judgment, which lien may be given priority
        over liens and encumbrances contracted by the controlling person after
        the control transaction date; and

             (4) Staying the action pending the determination of any similar
        action pending in another court having jurisdiction. [1985, c. 394, sec.
        3 (new).]

     [1985, c. 728 (amd).]

     10. HOLDING AND DISPOSAL OF SHARES ACQUIRED BY PAYMENT.  Shares acquired by
a controlling person pursuant to payment of the agreed value therefor or to
payment of the judgment entered therefor, as provided in this section, may be
held and disposed of as authorized and issued shares.

     [1985, c. 394, sec. 3 (new).]

     11. MINORS.  The demand required by subsection 4 may be made, in the case
of a shareholder who is a minor or otherwise legally incapacitated, either by
the shareholder, notwithstanding his legal incapacity, or by his guardian, or by
any person acting for him as next friend. The shareholder shall be bound by the
time limitations set forth in this section, notwithstanding his legal
incapacity.

     [1985, c. 394, sec. 3 (new).]

                                      II-4
<PAGE>   40

     12. APPEALS.  Appeals shall lie from judgments in actions brought under
this section as in other civil actions in which equitable relief is sought.

     [1985, c. 394, sec. 3 (new).]

     13. COMPLIANCE; SHAREHOLDER RIGHTS.  If a person or group of persons
proposing to engage in a control transaction complies with the requirements of
this section in connection with the control transaction, the effectiveness of
the rights afforded in this section to shareholders may be conditioned upon the
consummation of the control transaction.

     The person or group of persons shall give prompt written notice of the
     satisfaction of any such condition to each shareholder who has made demand
     as provided in this section.

     [1985, c. 394, sec. 3 (new).]

     14. APPLICATION.  This section does not apply to:

          A. Any corporation that is the subject of a control transaction and
     that does not have a class of voting shares:

             (1) Registered or traded on a national securities exchange; or

             (2) Registered with the Securities and Exchange Commission pursuant
        to the Act of Congress known as the Securities Exchange Act of 1934, as
        the same has been or may hereafter be amended, United States Code
        Annotated, Title 15, Section 78a et seq.; [1985, c. 394, sec. 3 (new).]

          B. Any person or group that inadvertently becomes a controlling person
     if that controlling person divests itself of a sufficient amount of its
     voting shares so that it is no longer a controlling person, as soon as
     practicable, but in no event more than 30 days after that person or group
     receives notice from the corporation that it has become a controlling
     person, or to any corporation that is the subject of a control transaction
     and that on the effective date of this section was a subsidiary of any
     other corporation. For purposes of this paragraph, "subsidiary" shall mean
     any corporation as to which any other corporation has acquired or has the
     right to acquire, directly or indirectly, through the exercise of warrants,
     options and rights and the conversion of all convertible securities,
     whether issued or granted by the subsidiary or otherwise, voting power over
     voting shares of the subsidiary that would entitle the holders thereof to
     cast in excess of 50% of the votes that all shareholders would be entitled
     to cast in the election of directors of that subsidiary; provided that a
     subsidiary will not be deemed to cease being a subsidiary so long as such
     corporation remains a controlling person within the meaning of subsection
     2; or [1985, c. 394, sec. 3 (new).]

          C. Any person or group that becomes a controlling person solely as a
     result of the corporation's purchase or redemption of its own voting
     shares. [1985, c. 394, sec. 3 (new).]

     [1985, c. 394, sec. 3 (new).]

                               SECTION 909 OF THE
                         MAINE BUSINESS CORPORATION ACT

13A SEC. 909. RIGHT OF DISSENTING SHAREHOLDERS TO PAYMENT FOR SHARES

     1. A shareholder having a right under any provision of this Act to dissent
to proposed corporate action shall, by complying with the procedure in this
section, be paid the fair value of his shares, if the corporate action to which
he dissented is effected. The fair value of shares shall be determined as of the
day prior to the date on which the vote of the shareholders, or of the directors
in case a vote of the shareholders was not necessary, was taken approving the
proposed corporate action, excluding any appreciation or depreciation of shares
in anticipation of such corporate action. [1971, c. 439, sec. 1 (new).]

     2. The shareholder, whether or not entitled to vote, shall file with the
corporation, prior to or at the meeting of shareholders at which such proposed
corporate action is submitted to a vote, a written objection to the proposed
corporate action. No such objection shall be required from any shareholder to
whom the corporation failed to send notice of such meeting in accordance with
this Act. [1971, c. 439, sec. 1 (new).]

     3. If the proposed corporate action is approved by the required vote and
the dissenting shareholder did not vote in favor thereof, the dissenting
shareholder shall file a written demand for payment of the fair value of his
shares. Such demand

          A. Shall be filed with the corporation or, in the case of a merger or
     consolidation, with the surviving or new corporation; and [1971, c. 439,
     sec. 1 (new).]

          B. Shall be filed by personally delivering it, or by mailing it via
     certified or registered mail, to such corporation at its registered office
     within this State or to its principal place of business or to the address
     given to the Secretary of State pursuant to section 906, subsection 4,
     paragraph B; it shall be so delivered or mailed within 15 days after the
     date on which the vote of shareholders was taken, or the date on which
     notice of a plan of merger of a subsidiary into a parent corporation
     without vote of shareholders was mailed to shareholders of the subsidiary;
     and [1971, c. 439, sec. 1 (new).]

          C. Shall specify the shareholder's current address; and [1971, c. 439,
     sec. 1 (new).]

          D. May not be withdrawn without the corporation's consent. [1971, c.
     439, sec. 1 (new).] [1971, c. 439, sec. 1 (new).]

     4. Any shareholder failing either to object as required by subsection 2 or
to make demand in the time and manner provided in subsection 3 shall be bound by
the terms of the proposed corporate action. Any shareholder making such
objection and demand shall thereafter be entitled only to payment as in this
section provided and shall not be entitled to vote or to exercise any other
rights of a shareholder. [1971, c. 439, sec. 1 (new).]

     5. The right of a shareholder otherwise entitled to be paid for the fair
value of his shares shall cease, and his status as a shareholder shall be
restored, without prejudice to any corporate proceedings which may have been
taken during the interim,

          A. If his demand shall be withdrawn upon consent, or [1971, c. 439,
     sec. 1 (new).]

          B. If the proposed corporate action shall be abandoned or rescinded,
     or the shareholders shall revoke the authority to effect such action, or
     [1971, c. 439, sec. 1 (new).]

          C. If, in the case of a merger, on the date of the filing of the
     articles of merger the surviving corporation is the owner of all the
     outstanding shares of the other corporations, domestic and foreign, that
     are parties to the merger, or [1971, c. 439, sec. 1 (new).]

          D. If no action for the determination of fair value by a court shall
     have been filed within the time provided in this section, or [1971, c. 439,
     sec. 1 (new).]

                                      III-1
<PAGE>   42

          E. If a court of competent jurisdiction shall determine that such
     shareholder is not entitled to the relief provided by this section. [1971,
     c. 439, sec. 1 (new).] [1971, c. 439, sec. 1 (new).]

     6. At the time of filing his demand for payment for his shares, or within
20 days thereafter, each shareholder demanding payment shall submit the
certificate or certificates representing his shares to the corporation or its
transfer agent for notation thereon that such demand has been made; such
certificates shall promptly be returned after entry thereon of such notation. A
shareholder's failure to do so shall, at the option of the corporation,
terminate his rights under this section, unless a court of competent
jurisdiction, for good and sufficient cause shown, shall otherwise direct. If
shares represented by a certificate on which notation has been so made shall be
transferred, each new certificate issued therefor shall bear a similar notation,
together with the name of the original dissenting holder of such shares, and a
transferee of such shares shall acquire by such transfer no rights in the
corporation other than those which the original dissenting shareholder had after
making demand for payment of the fair value thereof. [1971, c. 439, sec. 1
(new).]

     7. Within the time prescribed by this subsection, the corporation, or, in
the case of a merger or consolidation, the surviving or new corporation,
domestic or foreign, shall give written notice to each dissenting shareholder
who has made objection and demand as herein provided that the corporate action
dissented to has been effected, and shall make a written offer to each such
dissenting shareholder to pay for such shares at a specified price deemed by
such corporation to be the fair value thereof. Such offer shall be made at the
same price per share to all dissenting shareholders of the same class. The
notice and offer shall be accompanied by a balance sheet of the corporation the
shares of which the dissenting shareholder holds, as of the latest available
date and not more than 12 months prior to the making of such offer, and a profit
and loss statement of such corporation for the 12 months' period ended on the
date of such balance sheet. The offer shall be made within the later of 10 days
after the expiration of the period provided in subsection 3, paragraph B, for
making demand, or 10 days after the corporate action is effected; corporate
action shall be deemed effected on a sale of assets when the sale is
consummated, and in a merger or consolidation when the articles of merger or
consolidation are filed or upon which later effective date as is specified in
the articles of merger or consolidation as permitted by this Act. [1971, c. 439,
sec. 1 (new).]

     8. If within 20 days after the date by which the corporation is required,
by the terms of subsection 7, to make a written offer to each dissenting
shareholder to pay for his shares, the fair value of such shares is agreed upon
between any dissenting shareholder and the corporation, payment therefor shall
be made within 90 days after the date on which such corporate action was
effected, upon surrender of the certificate or certificates representing such
shares. Upon payment of the agreed value the dissenting shareholder shall cease
to have any interest in such shares. [1971, c. 439, sec. 1 (new).]

     9. If within the additional 20-day period prescribed by subsection 8, one
or more dissenting shareholders and the corporation have failed to agree as to
the fair value of the shares:

          A. Then the corporation may, or shall, if it receives a demand as
     provided in subparagraph (1), bring an action in the Superior Court in the
     county in this State where the registered office of the corporation is
     located praying that the fair value of such shares be found and determined.
     If, in the case of a merger or consolidation, the surviving or new
     corporation is a foreign corporation without a registered office in this
     State, such action shall be brought in the county where the registered
     office of the participating domestic corporation was last located. Such
     action:

             (1) Shall be brought by the corporation, if it receives a written
        demand for suit from any dissenting shareholder, which demand is made
        within 60 days after the date on which the corporate action was
        effected; and if it receives such demand for suit, the corporation shall
        bring the action within 30 days after receipt of the written demand; or,

             (2) In the absence of a demand for suit, may at the corporation's
        election be brought by the corporation at any time from the expiration
        of the additional 20-day period prescribed by subsection 8 until the
        expiration of 60 days after the date on which the corporate action was
        effected; [1971, c. 439, sec. 1 (new).]

                                      III-2
<PAGE>   43

          B. If the corporation fails to institute the action within the period
     specified in paragraph A, any dissenting shareholder may thereafter bring
     such an action in the name of the corporation; [1971, c. 439, sec. 1
     (new).]

          C. No such action may be brought, either by the corporation or by a
     dissenting shareholder, more than 6 months after the date on which the
     corporate action was effected; [1971, c. 439, sec. 1 (new).]

          D. In any such action, whether initiated by the corporation or by a
     dissenting shareholder, all dissenting shareholders, wherever residing,
     except those who have agreed with the corporation upon the price to be paid
     for their shares, shall be made parties to the proceeding as an action
     against their shares quasi in rem. A copy of the complaint shall be served
     on each dissenting shareholder who is a resident of this State as in other
     civil actions, and shall be served by registered or certified mail, or by
     personal service without the State, on each dissenting shareholder who is a
     nonresident. The jurisdiction of the court shall be plenary and exclusive;
     [1971, c. 439, sec. 1 (new).]

          E. The court shall determine whether each dissenting shareholder, as
     to whom the corporation requests the court to make such determination, has
     satisfied the requirements of this section and is entitled to receive
     payment for his shares; as to any dissenting shareholder with respect to
     whom the corporation makes such a request, the burden is on the shareholder
     to prove that he is entitled to receive payment. The court shall then
     proceed to fix the fair value of the shares. The court may, if it so
     elects, appoint one or more persons as appraisers to receive evidence and
     recommend a decision on the question of fair value. The appraisers shall
     have such power and authority as shall be specified in the order of their
     appointment or an amendment thereof; [1971, c. 439, sec. 1 (new).]

          F. All shareholders who are parties to the proceeding shall be
     entitled to judgment against the corporation for the amount of the fair
     value of their shares, except for any shareholder whom the court shall have
     determined not to be entitled to receive payment for his shares. The
     judgment shall be payable only upon and concurrently with the surrender to
     the corporation of the certificate or certificates representing such
     shares. Upon payment of the judgment, the dissenting shareholder shall
     cease to have any interest in such shares; [1971, c. 439, sec. 1 (new).]

          G. The judgment shall include an allowance for interest at such rate
     as the court may find to be fair and equitable in all the circumstances,
     from the date on which the vote was taken on the proposed corporate action
     to the date of payment. If the court finds that the refusal of any
     shareholder to accept the corporate offer of payment for his shares was
     arbitrary, vexatious or not in good faith, it may in its discretion refuse
     to allow interest to him; [1971, c. 439, sec. 1 (new).]

          H. The costs and expenses of any such proceeding shall be determined
     by the court and shall be assessed against the corporation, but all or any
     part of such costs and expenses may be apportioned and assessed as the
     court may deem equitable against any or all of the dissenting shareholders
     who are parties to the proceeding to whom the corporation shall have made
     an offer to pay for the shares, if the court shall find that the action of
     such shareholders in failing to accept such offer was arbitrary or
     vexatious or not in good faith. Such expenses shall include reasonable
     compensation for and reasonable expenses of the appraisers, but shall
     exclude the fees and expenses of counsel for any party and shall exclude
     the fees and expenses of experts employed by any party, unless the court
     otherwise orders for good cause. If the fair value of the shares as
     determined materially exceeds the amount which the corporation offered to
     pay therefor, or if no offer was made, the court in its discretion may
     award to any shareholder who is a party to the proceeding such sum as the
     court may determine to be reasonable compensation to any expert or experts
     employed by the shareholder in the proceeding, and may, in its discretion,
     award to any shareholder all or part of his attorney's fees and expenses;
     [1971, c. 439, sec. 1 (new).]

          I. At all times during the pendency of any such proceeding, the court
     may make any and all orders which may be necessary to protect the
     corporation or the dissenting shareholders, or which are otherwise just and
     equitable. Such orders may include, without limitation, orders:

             (1) Requiring the corporation to pay into court, or post security
        for, the amount of the judgment or its estimated amount, either before
        final judgment or pending appeal;
                                      III-3
<PAGE>   44

             (2) Requiring the deposit with the court of certificates
        representing shares held by the dissenting shareholders;

             (3) Imposing a lien on the property of the corporation to secure
        the payment of the judgment, which lien may be given priority over liens
        and encumbrances contracted after the vote authorizing the corporate
        action from which the shareholders dissent;

             (4) Staying the action pending the determination of any similar
        action pending in another court having jurisdiction. [1971, c. 439, sec.
        1 (new).] [1971, c. 439, sec. 1 (new).]

     10. Shares acquired by a corporation pursuant to payment of the agreed
value therefor or to payment of the judgment entered therefor, as in this
section provided, may be held and disposed of by such corporation as in the case
of other treasury shares, except that, in the case of a merger or consolidation,
they may be held and disposed of as the plan of merger or consolidation may
otherwise provide. [1971, c. 439, sec. 1 (new).]

     11. The objection required by subsection 2 and the demand required by
subsection 3 may, in the case of a shareholder who is a minor or otherwise
legally incapacitated, be made either by such shareholder, notwithstanding his
legal incapacity, or by his guardian, or by any person acting for him as next
friend. Such shareholder shall be bound by the time limitations set forth in
this section, notwithstanding his legal incapacity. [1971, c. 439, sec. 1
(new).]

     12. Appeals shall lie from judgments in actions brought under this section
as in other civil actions in which equitable relief is sought. [1971, c. 439,
sec. 1 (new).]

     13. No action by a shareholder in the right of the corporation shall abate
or be barred by the fact that the shareholder has filed a demand for payment of
the fair value of his shares pursuant to this section. [1971, c. 439, sec. 1
(new).]

     1971, c. 439, sec. 1,27 (NEW).

                             (Summary Advertisement)

         This announcement is neither an offer to purchase nor a solicitation of
an offer to sell Shares. The Offer is made solely by the Offer to Purchase dated
October 12, 1999 and the related Letter of Transmittal and any amendments or
supplements thereto, and is being made to all holders of Shares. The Offer is
not being made to, nor will tenders be accepted from or on behalf of, holders of
Shares in any jurisdiction in which the making of the Offer or acceptance
thereof would not be in compliance with the laws of such jurisdiction.

                     All Outstanding Shares of Common Stock
                                       of
                             Penobscot Shoe Company
                                       at
                              $11.75 Net Per Share
                                       by
                             PSC Acquisition Corp.
                     an indirect wholly-owned subsidiary of
                              Riedman Corporation


         PSC Acquisition Corp., a Maine corporation (the "Purchaser") and an
indirect wholly-owned subsidiary of Riedman Corporation, a corporation organized
and existing under the laws of the State of New York ("Parent"), is offering to
purchase all the outstanding shares of common stock, par value $1.00 per share
(the "Shares"), of Penobscot Shoe Company, a Maine corporation (the "Company"),
at a purchase price of $11.75 per Share, net to the seller in cash (subject to
applicable withholding of tax), without interest, upon the terms and subject to
the conditions set forth in the Offer to Purchase dated October 12, 1999 (the
"Offer to Purchase") and in the related Letter of Transmittal (which, as amended
or supplemented from time to time, together constitute the "Offer"). Tendering
stockholders who have Shares registered in their own name and who tender
directly to EquiServe, L.P. (the "Depository") will not be obligated to pay
brokerage fees or commissions or, subject to Instruction 6 of the Letter of
Transmittal, transfer taxes on the purchase of Shares pursuant to the Offer. The
purpose of the Offer is to acquire for cash as many outstanding Shares as
possible as a first step in acquiring the entire equity interest in the Company.
Following the consummation of the Offer, the Purchaser intends to effect the
merger described below.

================================================================================
         THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, EASTERN
STANDARD TIME, ON NOVEMBER 9, 1999, UNLESS THE OFFER IS EXTENDED.
================================================================================

         The Offer is conditioned upon, among other things, there having been
validly tendered and not withdrawn prior to the Expiration Date (as defined
below) at least 80% of the Company's outstanding common stock (the "Minimum
Condition"). Certain stockholders of the Company owning 740,321.5 Shares
representing 53.33% outstanding have agreed to tender their Shares in the Offer
pursuant to Tender Agreements which are fully described in the Offer to
Purchase.

         The Offer is being made pursuant to an Agreement and Plan of Merger,
dated October 6, 1999 (the "Merger Agreement"), by and among the Purchaser,
Parent and the Company. The Merger Agreement provides, among other things, that
the Purchaser will make the Offer and that as promptly as practicable following
the consummation of the Offer and the satisfaction or waiver of certain
conditions set forth in the Merger Agreement and in accordance with relevant
provisions of the Maine Business Corporation Act (the "Maine Law"), the
Purchaser will merge with and into the Company (the "Merger"). Upon the
consummation of the Merger, the Company will continue as the surviving
corporation and
<PAGE>   2
will be an indirect, wholly owned subsidiary of Parent. At the effective time of
the Merger (the "Effective Time"), each Share issued and outstanding immediately
prior to the Effective Time (other than Shares held by the Company as treasury
stock or by any subsidiary of the Company, Parent, the Purchaser or any other
subsidiary of Parent and other than Shares held by a holder who has not voted in
favor of the Merger or consented thereto in writing and who has demanded payment
of the fair value of such Shares pursuant to Section 910 of Maine Law or
demanded appraisal for such Shares in accordance with Section 909 of the Maine
Law) will be converted into the right to receive cash, without interest, in an
amount equal to the price per Share paid pursuant to the Offer.

         THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY DETERMINED THAT
THE OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY
AND ITS STOCKHOLDERS, HAS APPROVED THE OFFER AND THE MERGER AND RECOMMENDS THAT
THE COMPANY'S STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO
THE OFFER.

         The term "Expiration Date" means 12:00 Midnight, Eastern Standard Time,
on November 9, 1999, unless and until the Purchaser shall have extended the
period of time for which the Offer is open, in which event the term "Expiration
Date" shall mean the latest time and date at which the Offer, as so extended by
the Purchaser, shall expire. The Purchaser may, and may be required to, subject
to the terms of the Merger Agreement, extend the Offer. Any such extension will
be followed as promptly as practicable by public announcement thereof no later
than 9:00 a.m., Eastern Standard Time, on the next business day after the
previously scheduled Expiration Date. During any such extension, all Shares
previously tendered and not properly withdrawn will remain subject to the Offer,
subject to the right of a tendering stockholder to withdraw such stockholder's
Shares.

         If any condition to the Offer is not satisfied, the Purchaser may,
subject to certain terms of the Merger Agreement, (a) terminate the Offer and
not accept for payment or pay for any Shares and return all tendered Shares to
tendering stockholders or (b) waive all the unsatisfied conditions (other than
the Minimum Condition which cannot without the Company's consent be waived or
reduced below 80% of the total issued and outstanding Shares) and accept for
payment and pay for all Shares validly tendered prior to the Expiration Date or
(c) extend the Offer and, subject to the right of stockholders to withdraw
Shares until the Expiration Date as set forth below, retain the Shares that
have been tendered during the period for which the Offer is extended.

         For purposes of the Offer, the Purchaser shall be deemed to have
accepted for payment (and thereby purchased) validly tendered Shares, if, as and
when the Purchaser gives oral or written notice to the Depository of the
Purchaser's acceptance of such Shares for payment pursuant to the Offer. In all
cases, payment for Shares accepted for payment pursuant to the Offer will be
made by deposit of the purchase price therefor with the Depository, which will
act as agent for tendering stockholders for the purpose of receiving payment
from the Purchaser and transmitting payment to tendering stockholders. Under no
circumstances will interest on the purchase price of the Shares be paid by the
Purchaser by reason of any delay in making payment. Payment for Shares purchased
pursuant to the Offer will in all cases be made only after timely receipt by the
Depository of (i) certificates for such Shares (or timely confirmation of a
book-entry transfer of such Shares into the Depository's account at the
Book-Entry Transfer Facility (as defined in the Offer to Purchase)), and (ii)
the Letter of Transmittal (or a facsimile thereof) properly completed and duly
executed with all required signature guarantees or an Agent's Message (as
defined in the Offer to Purchase) in connection with a book-entry transfer of
Shares, together with any other documents required by the Letter of Transmittal.
<PAGE>   3
         Tenders of Shares made pursuant to the Offer may be withdrawn at any
time prior to the Expiration Date. Thereafter, such tenders are irrevocable,
except that they also may be withdrawn at any time after December 9, 1999 unless
theretofore accepted for payment as provided in the Offer to Purchase. For a
withdrawal to be effective, a written or facsimile transmission notice of
withdrawal must be timely received by the Depository at one of its addresses set
forth in the Offer to Purchase and must specify the name of the person who
tendered the Shares to be withdrawn and the number of Shares to be withdrawn and
the name of the registered holder, if different from that of the person who
tendered such Shares. If certificates for the Shares to be withdrawn have been
delivered or otherwise identified to the Depository, a signed notice of
withdrawal with signatures guaranteed by an Eligible Institution (as defined in
the Offer to Purchase) must be submitted prior to the release of such Shares,
unless such Shares were tendered by an Eligible Institution. In addition, such
notice must specify, in the case of Shares tendered by delivery of certificates,
the serial numbers shown on the particular certificates evidencing the Shares to
be withdrawn or, in the case of Shares tendered by a book-entry transfer, the
name and number of the account at the Book-Entry Transfer Facility (as defined
in the Offer to Purchase) to be credited with the withdrawn Shares.

         The information required to be disclosed by paragraph (e)(1)(vii) of
Rule 14d-6 of the General Rules and Regulations under the Securities Exchange
Act of 1934, as amended, is contained in the Offer to Purchase and is
incorporated herein by reference.

         The Company has provided the Purchaser with the Company's stockholder
lists and security position listings for the purpose of disseminating the Offer
to holders of Shares. The Offer to Purchase and the related Letter of
Transmittal and other related materials will be mailed to record holders of

                          AGREEMENT AND PLAN OF MERGER


         This AGREEMENT AND PLAN OF MERGER, dated as of October 6, 1999 (this
"Agreement"), by and among Riedman Corporation, a New York corporation
("Parent"), PSC Acquisition Corp., a Maine corporation and an indirect
wholly-owned subsidiary of Parent ("Purchaser"), and Penobscot Shoe Company,
a Maine corporation (the "Company").

                                R E C I T A L S :

         WHEREAS, Parent and Purchaser have proposed acquiring all the
outstanding common stock, par value $1.00 per share, of the Company, (the
"Shares" or "Company Common Stock") at a price of $11.75 per Share in cash;

         WHEREAS, the Company, Parent and Purchaser desire to make certain
representations, warranties, covenants and agreements in connection with the
Offer and the Merger;

         WHEREAS, as a condition and inducement to Parent's and Purchaser's
entering into this Agreement and incurring the obligations set forth herein,
several of the stockholders (the "Majority Stockholders") holding in the
aggregate approximately 53.33% of the outstanding shares of Company Common Stock
concurrently herewith entering into Tender Agreements (the "Tender Agreements"),
dated as of the date hereof, with Parent and Purchaser, pursuant to which, among
other things, they are agreeing to tender all of their Shares in the Offer, all
upon the terms and subject to the conditions set forth in the Tender Agreements;
and

         WHEREAS, the Boards of Directors of Parent, Purchaser and the Company
have approved, and deem it advisable and in the best interests of their
respective stockholders to consummate, the acquisition of the Company by Parent
and Purchaser upon the terms and subject to the conditions set forth herein;

                              P R O V I S I O N S :

         NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, the
parties hereto, intending to be legally bound hereby, agree as follows:

                                    ARTICLE I
                              THE OFFER AND MERGER

         SECTION 1.1 THE OFFER.

                  (a) Provided this Agreement shall not have been terminated in
accordance with Section 7.1, as promptly as practicable (but in no event later
than five (5) business days after the public announcement of the execution of
this Agreement), Purchaser shall, and Parent shall cause Purchaser to, commence
(within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as
amended (the "Exchange Act")), an offer (the "Offer") to purchase for cash any
and all shares of the issued and outstanding Company Common Stock at a price of
<PAGE>   8
$11.75 per Share, net to the seller in cash (such price, or such higher price
per Share as may be paid in the Offer being referred to herein as the "Offer
Price"), subject to the conditions set forth herein and in Annex A attached
hereto. The Company shall not tender Shares held by it or by any of its
Subsidiaries pursuant to the Offer and the Purchaser shall not be obligated to
purchase any such Shares. The obligations of Purchaser to consummate the Offer
and to accept for payment and to pay for any Shares validly tendered on or prior
to the expiration of the Offer and not withdrawn shall be subject only to there
being validly tendered and not withdrawn prior to the expiration of the Offer,
not less than eighty percent (80%) of the total issued and outstanding shares of
Company Common Stock on the date hereof (the "Minimum Condition") (which on this
date constitutes 1,110,633 Shares), and the other conditions set forth in Annex
A attached hereto. Except as expressly provided in Sections 1.1(b) and (c), the
Purchaser expressly reserves the right to waive any such condition, to increase
the price payable in the Offer and to make any other changes in the terms and
conditions of the Offer.

                  (b) The Offer shall be made by means of an offer to purchase
(the "Offer to Purchase") containing the terms set forth in this Agreement, the
Minimum Condition and the other conditions set forth in Annex A attached hereto.
Unless previously approved by the Company in writing, no change may be made by
Purchaser that (i) decreases the Offer Price, (ii) changes the form of
consideration to be paid in the Offer, (iii) reduces the maximum number of
Shares to be purchased in the Offer, (iv) imposes conditions to the Offer in
addition to those set forth in Annex A, (v) amends the conditions set forth in
Annex A to broaden the scope of such conditions, (vi) extends the Offer except
as provided in Section 1.1(c), or (vii) amends or waives the Minimum Condition.

                  (c) Subject to the terms and conditions hereof, the initial
expiration date of the Offer shall be twenty (20) business days after the
commencement of the Offer (as extended in accordance herewith, the "Expiration
Date"), subject to extension as provided in this Section 1.1(c). Notwithstanding
anything herein to the contrary, Purchaser shall be entitled (i) to extend the
Offer (and defer the Expiration Date) for a period ending no later than ninety
(90) days after the commencement of the Offer in one or more periods of not more
than ten (10) business days each, if at any scheduled Expiration Date, any
condition to the Offer is not satisfied or waived by Purchaser; (ii) to extend
the Offer (and defer the Expiration Date) for any period required by any rule,
regulation, interpretation or position of the Securities and Exchange Commission
(the "SEC") or the staff thereof applicable to the Offer; and (iii) to extend
the Offer (and defer the Expiration Date) further for an additional period
ending no more than one hundred fifty (150) days (in one or more periods of not
more than ten (10) business days each) following an extension pursuant to clause
(i) of this sentence, if at the Expiration Date, as deferred pursuant to clause
(i) of this sentence, the condition to the Offer set forth in paragraph (b)(i)
of Annex A has not been satisfied or waived or the condition to the Offer set
forth in paragraph (b)(v) of Annex A has not been satisfied or waived; and (iv)
at the Expiration Date, if all conditions to the Offer have been satisfied or
waived by Purchaser, and for so long as less than ninety percent (90%) of the
outstanding shares of Company Common Stock have been validly tendered and not
properly withdrawn pursuant to the Offer, Purchaser may, in its sole discretion
and without the consent of the Company, extend the Offer (and defer the
Expiration Date) for up to an additional ten (10) business days in the aggregate
(in periods of no more than five (5) business days each). Subject to the terms
and conditions of this Agreement, if any one or more of the conditions to the
Offer set forth on Annex A (other than the Minimum Condition) are not satisfied
or waived by Parent and Purchaser at the time of any scheduled Expiration Date,
then, provided, that such conditions are and continue to be reasonably capable
of being satisfied by December 31, 1999, Purchaser shall extend the Offer in
such intervals of no less than five (5) business days each up until December 31,
1999. Any extension of the Offer in accordance herewith shall defer the
Expiration Date until the latest date to which the Offer is so extended. Subject
to the terms and conditions of the Offer and this Agreement, Purchaser shall
(and Parent shall cause

                                      -2-
<PAGE>   9
Purchaser to) accept for payment, and pay for, all Shares validly tendered and
not withdrawn pursuant to the Offer, as promptly as practicable after the
expiration of the Offer.

                  (d) As soon as practicable on the date the Offer is commenced,
Parent and Purchaser shall file with the SEC a Tender Offer Statement on
Schedule 14D-1 with respect to the Offer (together with all amendments and
supplements thereto and including the exhibits thereto, the "Schedule 14D-1").
The Schedule 14D-1 shall include, as exhibits, the Offer to Purchase, a form of
related letter of transmittal and summary advertisement (collectively, together
with any amendments and supplements thereto, the "Offer Documents"). Parent and
Purchaser agree that they shall cause the Offer Documents to comply in all
material respects with the Exchange Act and the rules and regulations thereunder
and other applicable laws. Parent and Purchaser further agree that the Offer
Documents, on the date first published, sent or given to the Company's
stockholders, shall not contain any untrue statement of 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 were
made, not misleading, except that no representation or warranty is made by
Parent or Purchaser with respect to information supplied by the Company or any
of its stockholders in writing specifically for inclusion or incorporation by
reference in the Offer Documents. The Company agrees that the information
provided by the Company in writing specifically for inclusion or incorporation
by reference in the Offer Documents shall not 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 were made, not misleading. Each of Parent and
Purchaser shall take all steps necessary to cause the Offer Documents to be
filed with the SEC and to be disseminated to holders of Shares, in each case as
and to the extent required by applicable federal securities laws. Each of Parent
and Purchaser, on the one hand, and the Company, on the other hand, shall
promptly correct any information provided by it for use in the Offer Documents
if and to the extent that it shall have become false or misleading in any
material respect and Purchaser further shall take all steps necessary to cause
the Schedule 14D-1 as so corrected to be filed with the SEC and the Offer
Documents to be disseminated to holders of Shares, in each case as and to the
extent required by applicable federal securities laws. The Company and its
counsel shall be given reasonable opportunity to review and comment on the Offer
Documents prior to the filing thereof with the SEC. Parent and Purchaser agree
to provide in writing to the Company and its counsel any comments Parent,
Purchaser or their counsel may receive from the SEC or its staff with respect to
the Offer Documents promptly after receipt of such comments.

                  (e) Simultaneously with the execution of this Agreement,
Parent shall designate a bank or trust company (the "Paying Agent") to make
payments of the funds which holders of shares of Company Common Stock shall be
entitled as payment for their Shares which are tendered and accepted by
Purchaser or to which they otherwise become entitled to in connection with the
Merger as provided herein. Such amount shall hereinafter be referred to as the
"Payment Fund." The expenses of the Paying Agent may be paid from the Payment
Fund only to the extent of any interest that accrues thereon and to the extent
that such interest is insufficient to pay those expenses, the Parent shall pay
such expenses. Simultaneously with the execution and delivery hereof, Parent
shall take all steps necessary to deposit or cause the Purchaser to deposit with
an escrow agent, in escrow for the benefit of the Company's stockholders,
immediately available funds equal to the aggregate Offer Price for all Shares
outstanding as of the date hereof, together with the aggregate amount payable to
the holders of Options pursuant to Section 2.4. The escrow shall be established
pursuant to an Escrow

                                      -3-
<PAGE>   10
Agreement in the form of Exhibit A annexed hereto which shall be entered into by
the escrow agent and the parties hereto at the time that the escrow is
established. The Payment Fund shall not be used for any purpose that is not
provided herein. The Paying Agent may invest, if so directed by Parent or
Purchaser, the Payment Fund in obligations of the United States government or
any agency or instrumentality thereof, or in obligations that are guaranteed or
insured by the United States government or an agency or instrumentality thereof.
Any net profit resulting from, or interest or income produced by, such
investments shall be payable to Parent or Purchaser on demand. In the event at
the end of any calendar month after the Payment Fund is deposited with the
Payment Agent, the Payment Fund shall realize a loss on any such investment,
Parent shall promptly thereafter deposit in such Payment Fund cash in an amount
necessary so that the Payment Fund will be sufficient to satisfy all of the
Purchaser's remaining obligations originally contemplated to be paid out of such
Payment Fund.

         SECTION 1.2 COMPANY ACTIONS.

                  (a) The Company hereby approves of and consents to the Offer
and represents that (i) its Board of Directors, at a meeting duly called and
held on October 6, 1999, has, subject to the terms and conditions set forth
herein, (A) approved this Agreement and the transactions contemplated hereby,
including the Offer and the Merger (collectively, the "Transactions"),
determining that the Merger is advisable and that the terms of the Offer and the
Merger are fair to, and in the best interests of, the Company's stockholders and
such approval constitutes approval of the Offer, this Agreement and the Merger
for purposes of Section 611-A of the Maine Business Corporation Act (the
"MBCA"); and (B) resolved to recommend that the stockholders of the Company
accept the Offer, tender their Shares thereunder to Purchaser and approve and
adopt this Agreement and the Merger, provided that such recommendation may be
withdrawn, modified or amended as provided in Section 5.4(d) hereof and (ii) the
restrictions on "business combinations" contained in Section 611-A of the MBCA
are inapplicable to the transactions contemplated by this Agreement and the
Tender Agreements. The Company hereby consents to the inclusion in the Offer
Documents of the recommendation of its Board of Directors described in clause
(i)(B) of the immediately preceding sentence, unless and until such
recommendation is withdrawn or modified, in a manner adverse to Parent, in
accordance with Section 5.4(d) hereof. The Company has been advised by each of
its directors and executive officers that they intend to tender or cause to be
tendered to the Purchaser pursuant to the Offer all Shares beneficially owned by
them and to vote such Shares in favor of the approval and adoption of this
Agreement and the Transactions.

                  (b) Concurrently with the filing of the Schedule 14D-1, the
Company shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 (together with all amendments and supplements thereto and
including the exhibits thereto, the "Schedule 14D-9") which shall contain the
recommendation referred to in clause (i)(B) of Section 1.2(a) hereof. The
Company shall take all steps necessary to cause the Schedule 14D-9 to be
disseminated to holders of Shares to the extent required by applicable federal
securities laws. The Company agrees that it shall cause the Schedule 14D-9 to
comply in all material respects with the Exchange Act and the rules and
regulations thereunder and other applicable laws. The Company further agrees
that the Schedule 14D-9, on the date first published, sent or given to the
Company's stockholders, shall not 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 were made, not misleading, except that no

                                      -4-
<PAGE>   11
representation or warranty is made by the Company with respect to information
supplied by Parent or Purchaser in writing specifically for inclusion or
incorporation by reference in the Schedule 14D-9. Parent and Purchaser agree
that the information provided by them specifically in writing for inclusion or
incorporation by reference in the Schedule 14D-9 shall not 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 were made, not misleading. Each of the
Company, on the one hand, and Parent and Purchaser, on the other hand, shall
promptly correct any information provided by it for use in the Schedule 14D-9 if
and to the extent that it shall have become false or misleading in any material
respect and the Company further shall take all steps necessary to cause the
Schedule 14D-9 as so corrected to be filed with the SEC and to be disseminated
to holders of the Shares, in each case as and to the extent required by
applicable federal securities laws. Parent and its counsel shall be given
reasonable opportunity to review and comment on the Schedule 14D-9 prior to the
filing thereof with the SEC. The Company agrees to provide in writing to Parent
and its counsel any comments the Company or its counsel may receive from the SEC
or its staff with respect to the Schedule 14D-9 promptly after receipt of such
comments.

                  (c) In connection with the Offer, the Company shall promptly
furnish or cause to be furnished to Purchaser mailing labels, security position
listings and any available listing or computer file containing the names and
addresses of the record holders of the Shares as of a recent date, and shall
furnish Purchaser with such information and assistance as Purchaser or its
agents may reasonably request in communicating the Offer to the stockholders of
the Company. Except for such steps as are necessary to disseminate the Offer
Documents and to consummate the Merger, and subject to the requirements of
applicable law, each of Parent and Purchaser and their agents shall hold in
confidence until the Effective Time the information contained in any of such
labels and lists and the additional information referred to in the preceding
sentence, shall use such information only in connection with the Offer and
Merger and, if this Agreement shall be terminated, will deliver, and will use
their reasonable efforts to cause their agents to deliver, to the Company all
copies and any extracts or summaries from such information then in their
possession or control or to destroy the same.

         SECTION 1.3 DIRECTORS.

                  (a) So long as this Agreement is in effect, the Company shall
not cause or permit the size of its Board of Directors to be expanded to more
than five (5) directors. Promptly upon the purchase of and payment for Shares by
Parent or Purchaser pursuant to the Offer, if the Minimum Condition has been
met, Parent shall, upon request, be entitled to designate three (3) directors to
the Company's Board of Directors. The Company shall, upon request of Purchaser
or Parent, secure the resignations of such number of its incumbent directors as
is necessary, consistent with the request of Purchaser or Parent, to enable
Parent's designees to be so elected to the Company's Board of Directors, and
shall take all actions necessary to cause Parent's designees to be so elected or
appointed. At such times, the Company will use its best efforts to cause
individuals designated by Parent to constitute the same percentage as such
individuals represent on the Company's Board of Directors on each committee of
the Board. Notwithstanding the foregoing, until the Effective Time, the Company
shall retain as members of its Board of Directors two (2) directors who are
directors of the Company on the date hereof (the "Continuing Directors");
provided, however, that upon and after satisfaction of the Minimum Condition and
subsequent to the purchase of and payment for Shares pursuant to the Offer,
Parent shall always have its designees represent at least a majority

                                      -5-
<PAGE>   12
of the entire Board of Directors. If a Continuing Director resigns from the
Company's Board of Directors, Parent, Purchaser and the Company shall permit the
remaining Continuing Director to appoint the resigning Director's successor who
shall be deemed to be a Continuing Director. The Company's obligations under
this Section 1.3(a) shall be subject to Section 14(f) of the Exchange Act and
Rule 14f-1 promulgated thereunder. Parent or Purchaser shall supply to the
Company in writing and be solely responsible for any information with respect to
either of them and their nominees, officers, directors and affiliates required
by Section 14(f) and Rule 14f-1. Upon receipt of such information from Parent or
Purchaser, the Company shall include in the Schedule 14D-9 (as an annex or
otherwise) the information required by Section 14(f) and Rule 14f-1 as is
necessary to enable Parent's designees to be elected to the Company's Board of
Directors.

                  (b) From and after the time, if any, that Parent's designees
constitute a majority of the Company's Board of Directors (the "Appointment
Date"), the unanimous vote of the entire Board of Directors of the Company,
including the Continuing Directors, is required for the Company to: (i) amend or
terminate this Agreement, (ii) extend the time for performance of any of the
obligations or other acts of Parent or Purchaser hereunder except as otherwise
specifically permitted herein, or (iii) waive any condition of the Company's
obligations hereunder or any of the Company's rights or remedies hereunder.

         SECTION 1.4 THE MERGER. Subject to the terms and conditions of this
Agreement and the provisions of the MBCA, at the Effective Time, the Company and
Purchaser shall consummate a merger (the "Merger") pursuant to which (a) the
Purchaser shall be merged with and into the Company and the separate corporate
existence of Purchaser shall thereupon cease, (b) the Company shall be the
successor or surviving corporation in the Merger (the "Surviving Corporation")
and shall continue to be governed by the laws of the State of Maine, and (c) the
separate corporate existence of the Company with all its rights, privileges,
immunities, powers and franchises shall continue unaffected by the Merger.
Pursuant to the Merger, (x) the Articles of Incorporation of Purchaser, as in
effect immediately prior to the Effective Time, shall be the Articles of
Incorporation of the Surviving Corporation until thereafter amended as provided
by law and such Articles of Incorporation, and (y) the By-Laws of Purchaser, as
in effect immediately prior to the Effective Time, shall be the By-Laws of the
Surviving Corporation until thereafter amended as provided by law, the Articles
of Incorporation and such By-Laws. The Merger shall have the effects set forth
in the MBCA. Without limiting the generality of the foregoing and subject
thereto, at the Effective Time, all the property, rights, privileges, powers and
franchises of the Company and the Purchaser shall vest in the Surviving
Corporation, and all debts, liabilities, obligations, restrictions, disabilities
and duties of the Company and the Purchaser shall become the debts, liabilities,
obligations, restrictions, disabilities and duties of the Surviving Corporation.

         SECTION 1.5 EFFECTIVE TIME. Subject to the terms and conditions set
forth in this Agreement, Parent, Purchaser and the Company shall cause Articles
of Merger (the "Articles of Merger") be executed and filed on the date of the
Closing (or on such other date as Parent and the Company may agree) with the
Secretary of State of the State of Maine (the "Maine Secretary") as provided in
Section 903 of the MBCA (or, if permitted, Section 904 of the MBCA). The Merger
shall become effective on the date and at the time on which the Articles of

                                      -6-
<PAGE>   13
Merger have been duly filed with the Maine Secretary or on such other date and
at such other time as the parties hereto may agree and as may be set forth in
the Articles of Merger (such time being the "Effective Time").

         SECTION 1.6 CLOSING. The closing of the Merger (the "Closing") shall
take place at 10:00 a.m., Eastern Standard Time, on a date to be specified by
the parties, which shall be as soon as practicable, but in no event later than
the third (3rd) business day after satisfaction or waiver of all the conditions
set forth in Article VI hereof (the "Closing Date"), at the offices of Woods,
Oviatt, Gilman, Sturman & Clarke LLP, Rochester, New York, unless another date
or place is agreed to in writing by the parties hereto.

         SECTION 1.7 DIRECTORS AND OFFICERS OF THE SURVIVING CORPORATION. The
directors and Chief Executive Officer of Purchaser and the officers of the
Company (other than the Chief Executive Officer) immediately prior to the
Effective Time shall, from and after the Effective Time, be the directors, Chief
Executive Officer and other officers, respectively, of the Surviving Corporation
until their successors shall have been duly elected or appointed or qualified or
until their earlier death, resignation or removal in accordance with the
Surviving Corporation's Certificate of Incorporation and By-Laws.

         SECTION 1.8 STOCKHOLDERS' MEETING.  Notwithstanding Section 1.9 hereof:

                  (a) Following consummation of the Offer, if required by
applicable law in order to consummate the Merger, the Company, acting through
its Board of Directors, shall, in accordance with applicable law and its
Articles of Incorporation and By-Laws:

                           (i) duly call, give notice of, convene and hold a
special meeting of its stockholders as soon as practicable following the
acceptance for payment and purchase of Shares by Purchaser pursuant to the Offer
for the purpose of considering and taking action upon this Agreement;

                           (ii) prepare and file with the SEC a preliminary
proxy or information statement relating to the Merger and this Agreement and use
its reasonable efforts (x) to obtain and furnish the information required to be
included by the SEC in the Proxy Statement and, after consultation with Parent,
to respond promptly to any comments made by the SEC with respect to the
preliminary proxy or information statement and cause a definitive proxy or
information statement (the "Proxy Statement") to be mailed to its stockholders
and (y) to obtain the necessary approvals of the Merger and this Agreement by
its stockholders; and

                           (iii) subject to Section 5.4(d), include in the Proxy
Statement the recommendation of the Board that stockholders of the Company vote
in favor of the approval of the Merger and the adoption of this Agreement.

                  (b) Parent shall provide the Company with the information
concerning Parent and Purchaser required to be included in the Proxy Statement.
Parent shall vote, or cause to be voted, all the Shares then owned by it,
Purchaser or any of its other subsidiaries and affiliates in favor of the
approval of the Merger and the approval and adoption of this Agreement.

                                      -7-
<PAGE>   14
         SECTION 1.9 MERGER WITHOUT MEETING OF STOCKHOLDERS. Notwithstanding the
foregoing, in the event that Parent or Purchaser shall acquire at least ninety
percent (90%) of the outstanding shares of Company Common Stock pursuant to the
Offer, each of the parties hereto agree to cooperate and to take all reasonable
necessary actions so that the Merger can be approved without a meeting of
stockholders of the Company, in accordance with Section 904 of the MBCA, if
possible.

                                   ARTICLE II
                            CONVERSION OF SECURITIES

         SECTION 2.1 CONVERSION OF CAPITAL STOCK. As of the Effective Time, by
virtue of the Merger and without any action on the part of the holders of any
shares of Company Common Stock or common stock, par value $.001 per share, of
Purchaser (the "Purchaser Common Stock"):

                  (a) Each issued and outstanding share of the Purchaser Common
Stock issued and outstanding immediately prior to the Effective Time shall be
converted into and become one validly issued, fully paid and nonassessable share
of common stock, par value $1.00 per share, of the Surviving Corporation.

                  (b) All shares of Company Common Stock that are owned by
Parent, Purchaser or by the Company as treasury stock immediately prior to the
Effective Time shall be cancelled and retired and shall cease to exist and no
consideration shall be delivered in connection therewith.

                  (c) Each share of Company Common Stock issued and outstanding
immediately prior to the Effective Time (other than Shares to be cancelled in
accordance with Section 2.1(b) hereof, any shares of Demanding Common Stock and
any shares of Dissenting Common Stock) shall be converted into the right to
receive the Offer Price payable to the holder thereof, without interest (the
"Merger Consideration"), upon surrender of the certificate formerly representing
such share of Company Common Stock in the manner provided in Section 2.2 hereof.
All such shares of Company Common Stock, when so converted, shall no longer be
outstanding and shall automatically be cancelled and retired and shall cease to
exist, and each holder of a certificate representing any such shares shall cease
to have any rights with respect thereto, except the right to receive the Merger
Consideration therefor upon the surrender of such certificate in accordance with
Section 2.2 hereof, without interest, or (i) in the case of Demanding Common
Stock, the right, if any, to receive payment from Purchaser for the "fair value"
of such shares as determined in accordance with Section 910 of the MBCA or (ii)
in the case of Dissenting Common Stock, the right, if any, to receive payment
from the Surviving Corporation for the "fair value" of such shares as determined
in accordance with Section 909 of MBCA.

         SECTION 2.2 EXCHANGE OF CERTIFICATES.

                  (a) Promptly after the Effective Time, the Surviving
Corporation shall cause the Paying Agent to mail to each holder of record of a
certificate or certificates, which immediately prior to the Effective Time
represented outstanding shares of Company Common Stock (the "Certificates"),
whose shares were converted pursuant to Section 2.1(c) hereto into the

                                      -8-
<PAGE>   15
right to receive the Merger Consideration, (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 Paying
Agent and shall be in such form and have such other provisions as Parent and the
Surviving Corporation may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for payment of the
Merger Consideration; provided, however, that such letter of transmittal shall
be substantially in the form and substance of a letter of transmittal and
instructions approved by the Company prior to the Effective Time, such approval
not to be unreasonably withheld. Upon surrender of a Certificate for
cancellation to the Paying Agent, together with such letter of transmittal, duly
completed and validly executed, the holder of such Certificate shall be entitled
to receive in exchange therefor the Merger Consideration (subject to subsection
(e) below) for each share of Company Common Stock formerly represented by such
Certificate and the Certificate so surrendered shall forthwith be cancelled. If
payment of the Merger Consideration is to be made to a Person other than the
Person in whose name the surrendered Certificate is registered, it shall be a
condition of payment that the Certificate so surrendered shall be properly
endorsed or shall otherwise be in proper form for transfer and that the Person
requesting such payment shall have paid any transfer and other taxes required by
reason of the payment of the Merger Consideration to a Person other than the
registered holder of the Certificate surrendered or shall have established to
the satisfaction of the Surviving Corporation that such tax either has been paid
or is not applicable. For purposes of this Agreement, the term "Person" shall
mean an individual, corporation, partnership, limited liability company, joint
venture, association, trust, estate, unincorporated organization or other
entity. Until surrendered as contemplated by this Section 2.2, each Certificate
shall be deemed at any time after the Effective Time to represent only the right
to receive the Merger Consideration in cash as contemplated by this Section
2.2(c) or (A) in the case of Dissenting Common Stock, the right, if any, to
receive payment from the Surviving Corporation for the "fair value" of the
Shares in accordance with Section 909 of the MBCA and (B) in the case of
Demanding Common Stock, the right, if any, to receive payment from Purchaser for
the "fair value" of such Shares determined in accordance with Section 910 of the
MBCA.

                  (b) At the Effective Time, the stock transfer books of the
Company shall be closed and thereafter there shall be no further registration of
transfers of shares of Company Common Stock on the records of the Company. From
and after the Effective Time, the holders of Certificates evidencing ownership
of shares of Company Common Stock outstanding immediately prior to the Effective
Time shall cease to have any rights with respect to such Shares, except as
otherwise provided for herein or by applicable law. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be cancelled and exchanged as provided in this Article II.

                  (c) At any time following one hundred eighty (180) days after
the Effective Time, the Surviving Corporation shall be entitled to require the
Paying Agent to deliver to it any funds (including any interest received with
respect thereto) which had been made available to the Paying Agent and which
have not been disbursed to holders of Certificates, and thereafter such holders
shall be entitled to look only to the Surviving Corporation (subject to
abandoned property, escheat or other similar laws) as general creditors thereof
with respect to the payment of any Merger Consideration that may be payable upon
surrender of any Certificates such stockholder holds, as determined pursuant to
this Agreement, without any interest thereon. Notwithstanding the foregoing,
neither the Surviving Corporation nor the Paying Agent shall be liable to any
holder of a Certificate for Merger Consideration delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

                                      -9-
<PAGE>   16
                  (d) In the event that any Certificate for Shares shall have
been lost, stolen or destroyed, the Paying Agent shall issue in exchange
therefor the Merger Consideration upon the making of an affidavit of that fact
by the holder thereof; provided, however, that Parent or the Paying Agent may,
in its discretion, require the delivery of a suitable bond or indemnity.

                  (e) Parent, Purchaser, the Surviving Corporation and the
Paying Agent shall be entitled to deduct and withhold from the consideration
otherwise payable to a holder of Shares pursuant to the Offer or Merger such
amounts as Parent, Purchaser, the Surviving Corporation or the Paying Agent is
required to deduct and withhold with respect to the making of such payment under
the Internal Revenue Code of 1986, as amended (the "Code"), or any provision of
state, local or foreign tax law, it being acknowledged that Parent, Purchaser,
the Surviving Corporation or the Paying Agent shall not deduct or withhold from
the consideration otherwise payable to any such holder of Shares pursuant to the
Offer or the Merger any amount with respect to which such holder has timely
delivered to Parent, Purchaser, the Surviving Corporation or the Paying Agent,
as the case may be, a properly executed Form W-9 in accordance with applicable
law. Any amounts so withheld shall be delivered to the applicable taxing
authority for the account of such holder of shares of Company Common Stock from
whom the amount was withheld. To the extent amounts are so withheld by Parent,
Purchaser, the Surviving Corporation or the Paying Agent, the withheld amounts
shall be treated for all purposes of this Agreement as having been paid to the
holder of the Shares in respect of which the deduction and withholding was made.

         SECTION 2.3 DEMANDING SHARES / DISSENTING SHARES. Notwithstanding any
provision of this Agreement to the contrary, if and to the extent required by
the MBCA, shares of Company Common Stock which are issued and outstanding
immediately prior to the Effective Time and which are held by holders of such
shares of Company Common Stock who have properly exercised demand payment rights
with respect thereto (the "Demanding Common Stock") in accordance with Section
910 of the MCBA or appraisal rights with respect thereto (the "Dissenting Common
Stock") in accordance with Section 909 of the MBCA, shall not be exchangeable
for the right to receive the Merger Consideration, and holders of such shares of
Demanding Common Stock or Dissenting Common Stock shall be entitled to receive
payment of the fair value of such shares of Demanding Common Stock or Dissenting
Common Stock in accordance with the provisions of Section 910 or Section 909,
respectively, of the MBCA unless and until such holders fail to perfect or
effectively withdraw or otherwise lose their rights to appraisal and payment
under the MBCA. If, after the Effective Time, any such holder fails to perfect
or effectively withdraws or loses such right, such shares of Demanding Common
Stock or Dissenting Common Stock shall thereupon be treated as if they had been
converted into and to have become exchangeable for, at the Effective Time, the
right to receive the Merger Consideration, without any interest thereon.
Notwithstanding anything to the contrary contained in this Section 2.3, if (i)
the Merger is rescinded or abandoned or (ii) the directors or stockholders of
the Company revoke the authority to effect the Merger, then the right of any
stockholder to be paid the fair value of such stockholder's Dissenting Common
Stock pursuant to Section 909 of the MBCA shall cease. The Company shall give
Parent prompt notice of any demands received by the Company for appraisals of
shares of Dissenting Common Stock (and shall also give Parent prompt notice of
any withdrawals of such demands) and Parent shall have the right to participate
in and direct all negotiations and proceedings with respect to such demands. The
Company shall not, except with the prior written consent of Parent, make any
payment with respect to any demands for appraisals or offer to settle or settle
any such demands.

         SECTION 2.4 TERMINATION OF COMPANY OPTIONS AND OPTION PLAN

                  (a) The Company shall take all actions necessary to provide
that, effective as of the date hereof, no further options to purchase Shares
("Options") may be granted under the Company's 1991 Stock Option Plan (the
"Option Plan").

                  (b) The Company represents and warrants that, under the terms
of the outstanding Options, all such Options shall, as of the Effective Time, be
automatically cancelled and terminated and of no further force or effect,
provided the holders of such Options receive from the Company an amount equal to
the product of (i) the excess, if any, of the Offer Price over the exercise
price of each such cancelled and terminated Option and (ii) the number of Shares
subject thereto (such payment, if any, to be net of applicable withholding
taxes) (the "Option Price"). Prior to the Effective Time, holders of Options
outstanding on the date hereof (including those which are unvested and shall
accelerate and vest on the date of the closing of the Offer) may exercise their
Options and tender the Shares issued in connection therewith to Purchaser
pursuant to the Offer. Further, prior to the consummation of the Offer, holders
of Options outstanding on the date hereof may transfer their Options to
Purchaser and execute such documentation as Purchaser may require. In
consideration for the transfer of such Options, the Purchaser shall pay to the
holders of such transferred Options as of the consummation of the Offer an
amount equal to the Option Price for the transferred Options. The Company
represents and warrants and covenants to take such actions as may be necessary
so that as of the Effective Time, all rights and obligations of the Company and
the holder of any Option under any provision of the Option Plan (or any other
plan, program or arrangement with respect to equity securities of the Company),
any agreement entered into thereunder or any other plan, program or arrangement
providing for the issuance or grant of any other interest in respect of the
capital stock of the Company shall be cancelled. The Company shall promptly
deliver to Parent prior to the closing of the Offer true and complete copies of
all documentation (all of which shall be reasonably satisfactory to Parent)
ensuring that the foregoing is effected.


                                   ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company represents and warrants to Parent and Purchaser that the
statements contained in this Article III are correct and complete, except as set

of the Disclosure Schedule, be deemed to be disclosed with respect to such
section of the Disclosure Schedule.

         SECTION 3.1 ORGANIZATION.

                  (a) The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Maine and has all
requisite corporate or other power and authority to own, lease and operate its
properties and to carry on its business as it is now being conducted, except
where the failure to be in good standing or to have such power or authority
would not have a Company Material Adverse Effect. The Company has no
Subsidiaries and does not hold any equity or other ownership interest, or any
interest convertible into or exercisable for any equity or similar interest in,
any corporation, partnership or joint venture or other business association or
entity. As used in this Agreement, the word "Subsidiary" means, with respect to
any Person any other Person of which (i) the first Person or any of its other
Subsidiaries is a general partner (excluding partnerships in which the first
Person or any of its other Subsidiaries do not have at least fifty percent (50%)
of the voting interest) or (ii) at least fifty percent (50%) of the securities

majority of the Board of Directors or others performing similar functions with
respect to such other Person is directly or indirectly owned or controlled by
the first Person and/or by any one or more of its Subsidiaries. As used in this
Agreement, the term "Company Material Adverse Effect" means any event, change or
effect (i) that is, or is reasonably expected to be, materially adverse to the
business, operations, properties, condition (financial or otherwise), assets,
liabilities (contingent or otherwise) or results of operations of the Company,
either individually or in the aggregate with similar events, changes or effects
or (ii) which impairs the ability of the Company to consummate the transactions
contemplated hereby; provided, however, that there shall be excluded from
determination of any Company Material Adverse Effect under (i) any event, change
or effect to the extent that it results from or arises from or relates to (x)
changes in the industry in which the Company operates (including legal and
regulatory changes): (y) the execution of this Agreement and the announcement of
this Agreement and the transactions contemplated hereby, including, but not
limited to, (A) any stockholder litigation brought or threatened against the
Company or any member of the Board of Directors of the Company in respect of
this Agreement, the Offer or the Merger, or (B) any reduction or termination of
orders received by the Company employees, distributors or resellers or (C) the
cessation of employment by Company employees; and (z) any change in the market
price of the Company Common Stock.

                  (b) The Company is duly qualified or licensed to do business
and in good standing in each jurisdiction in which the property owned, leased or
operated by it or the nature of the business conducted by it makes such
qualification or licensing necessary, except where the failure to be so duly
qualified or licensed and in good standing would not in the aggregate have a
Company Material Adverse Effect.

                  (c) The Company has heretofore delivered to Parent a complete
and correct copy of each of its Articles of Incorporation and By-Laws, as
currently in effect. In all material respects, the minute books of the Company
contain accurate records of all meetings and accurately reflect all other
actions taken by the stockholders, the Boards of Directors and all committees of
the Boards of Directors of the Company. Except as set forth on Schedule 3.1(b)
attached hereto, complete and accurate copies of all such minute books and of
the stock register of the Company have been made available by the Company to the

This Agreement has been duly executed and delivered by the Company and, assuming

other similar laws, now or hereafter in effect, affecting creditors' rights
generally, and (ii) the remedy of specific performance and injunctive and other
forms of equitable relief may be subject to equitable defenses and to the

(ii), (iii), (iv) or (v) where the failure to obtain such permits,

         SECTION 3.5 SEC REPORTS AND FINANCIAL STATEMENTS. The Company has filed
with the SEC all forms, reports, schedules, statements and other documents
required to be filed by it under the Exchange Act since November 11, 1997
through the date hereof (as such documents have been amended since the time of
their filing, collectively, the "Company SEC Documents"). As of their respective
dates and, if amended, as of the date of the last such amendment, the Company
SEC Documents, including, without limitation, any financial statements or
schedules included therein, did not 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 light of the circumstances under
which they were made, not misleading. The financial statements of the Company
(the "1998 Financial Statements") included in the Company's Annual Report on
Form 10-K for the fiscal year ended November 27, 1998 (including the related
notes thereto) (the "1998 Form 10-K") and in the quarterly report on Form 10-Q
for the fiscal quarters occurring since the 1998 Form 10-K, have been prepared
from, and are in accordance with, the books and records of the Company comply in
all material respects with applicable accounting requirements and with the
published rules and regulations of the SEC with respect thereto have been
prepared in accordance with United States generally accepted accounting
principles ("GAAP") applied on a consistent basis during the periods involved

unaudited interim financial statements, to normal year-end adjustments and to
the absence of complete notes) and fairly present in all material respects the
financial position and the results of operations and cash flows of the Company
as at the dates thereof or for the periods presented therein. Except as
disclosed in the Company SEC Documents, the books and records of the Company
have been, and are being, maintained, in all material respects, in accordance
with GAAP and any other applicable legal and accounting requirements (subject to
normal year-end audit adjustments and the absence of notes).

Ordinary Course of Business consistent with past practices since November 27,
1998, and (c) for liabilities and obligations incurred in connection with the
consummation of the transactions contemplated hereby, the Company has not
incurred any liabilities or obligations of any kind whatsoever, whether accrued,
contingent, absolute, determined, determinable or otherwise and there is no
existing condition, situation or set of circumstances which could reasonably be
expected to result in such a liability or obligation. "Ordinary Course of
Business" means the ordinary and usual course of business of the Company
consistent with the Company's past custom and practice, including with respect
to quantity and frequency.

         SECTION 3.7 ABSENCE OF CERTAIN CHANGES. Except as disclosed in the
Company SEC Documents filed to the prior date hereof or on Schedule 3.7 annexed
hereto, since November 27, 1998, the Company has conducted its business in the
Ordinary Course of Business and there has not been (a) any change in the
financial condition, business or results of operations of the Company or the
amount, character or ownership interests of the Company's assets that resulted
in or would be reasonably expected to result in a Company Material Adverse
Effect; (b) any declaration, setting aside or payment of any dividend or other
distribution (whether in cash, stock or property) with respect to the
outstanding capital stock of the Company; (c) any material change by the Company
in accounting principles or methods, except insofar as may have been required by
GAAP; (d) any split, combination or reclassification of shares of the Company's
capital stock or any issuance or the authorization of any issuance of any other
securities in respect of, in lieu of or in substitution of any outstanding
capital stock or other equity interest of the Company; (e) any entry into any
written employment agreement with, or any increase in the rate or terms of
compensation payable or to become payable by the Company to any directors,
officers or key employees; (f) any increase in the rate or terms (including,
without limitation, any acceleration of the right to receive payment) of any
bonus, insurance, pension or other employee benefit plan, payment or arrangement
made to, for or with any such directors, officers or key employees, except for
increases occurring in the Ordinary Course of Business; (g) any amendment or
restatement to the Articles of Incorporation or By-Laws of the Company; (h) any
damage or destruction or loss of property (whether or not covered by insurance)
that individually or in the aggregate would result in Company Material Adverse
Effect; or (i) any sale, lease, transfer or assignment of any assets of the
Company other than in the Ordinary Course of Business, provided that no such
sale, lease, transfer of assignment has involved any assets (other than
inventory sold in the Ordinary Course of Business) which are material or which
in the aggregate are material.

         SECTION 3.8 EMPLOYEE BENEFIT PLANS; ERISA.

                  (a) Schedule 3.8(a) annexed hereto contains a true and
complete list of each deferred compensation, bonus, profit sharing, stock
option, pension, incentive compensation, and equity compensation plan, welfare
plan, fund or program (within the meaning of section 3(1) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")), "pension" plan,
fund or program (within the meaning of Section 3(2) of ERISA), each employment,
consulting, change in control, termination or severance agreement or policy, and
each fringe benefit, insurance, welfare, post-retirement, health, life, tuition
refund, scholarship, relocation, disability,

                                      -15-
<PAGE>   22
accident, sick, vacation, commission, payroll practices, retention,
non-competition or any other employee benefit plan, fund, program agreement or
arrangement (whether written or unwritten, insured or self-insured)), in each
case, that is or was sponsored, maintained or contributed to or required to be
contributed to by the Company or by any trade or business, whether or not
incorporated (an "ERISA Affiliate"), that together with the Company would be
deemed a "single employer" within the meaning of Section 4001(b) of ERISA or
Section 414(b), (c), (m) or (o) of the Code, or to which the Company or an ERISA
Affiliate is a party, for the benefit of any employee, director or stockholder
of the Company (whether current, former or retired) or their beneficiaries or to
which the Company or any ERISA Affiliate has or could reasonably be expected to
have any liability (the "Benefit Plans").

                  (b) With respect to each Benefit Plan, the Company has made
available to Purchaser and Parent true and complete copies of the Benefit Plan
documents, including amendments, and summary plan descriptions (or if the
Benefit Plan is not a written Benefit Plan, a description thereof), any related
trust, instruments, insurance vehicles or other instruments establishing a
funding vehicle, the three (3) most recent Form 5500 reports, financial
statements or summaries required under ERISA or the Code, the most recent
determination letter received from the Internal Revenue Service (the "IRS") with
respect to each Benefit Plan intended to qualify under Section 401 of the Code
and any communication received by or furnished to the Company or any ERISA
Affiliate from the IRS or any other governmental entity.

                  (c) No liability under Title IV or Section 302 of ERISA has
been incurred by the Company or any ERISA Affiliate that has not been satisfied
in full, and no condition exists that presents a risk to the Company or any
ERISA Affiliate of incurring any such liability, other than liability for
premiums due the Pension Benefit Guaranty Corporation (the "PBGC") (which
premiums have been paid when due).

                  (d) No Benefit Plan is a "multiemployer pension plan," as
defined in Section 3(37) or 4001(a)(3) of ERISA, or Section 414(f) of the Code
(a "Multiemployer Plan") nor is any Benefit Plan a plan described in Section
4063(a) of ERISA.

                  (e) Each Benefit Plan intended to be "qualified" within the
meaning of section 401(a) of the Code has received a determination letter from
the Internal Revenue Service to the effect that it is so qualified and, to the
Knowledge (as defined herein) of the Company, nothing has occurred or is
reasonably expected to occur through the Effective Time that caused or could
cause the loss of such qualification or exemption or the imposition of any
penalty or tax liability. "Knowledge" means actual knowledge after reasonable
inquiry provided that Knowledge of Persons that are not natural persons shall
mean only actual personal knowledge of such Persons' executive officers after
reasonable inquiry.

                  (f) No Benefit Plan provides medical, surgical,
hospitalization, death or similar benefits (whether or not insured) for
employees or former employees of the Company for periods extending beyond their
retirement or other termination of service, other than (i) coverage mandated by
applicable law, or (ii) death benefits under any "pension plan".

                  (g) There are no pending or, to the Knowledge of the Company,
threatened or anticipated claims by or on behalf of any Benefit Plan, by any
employee or beneficiary covered

                                      -16-
<PAGE>   23
under any such Benefit Plan, or otherwise involving any such Benefit Plan (other
than routine claims for benefits).

                  (h) With respect to each of the Benefit Plans on Schedule
3.8(a): (i) all payments required by any Benefit Plan, any collective bargaining
agreement or other agreement, or by-law (including, without limitation, all
contributions, insurance premiums, or inter-company charges) with respect to all
periods through the date of the Effective Time shall have been made prior to the
Effective Time or provided for by the Company as applicable, by full accruals
(as if all targets required by such Benefit Plan had been or will be met at
maximum levels) on its financial statements; (ii) no "accumulated funding
deficiency" (within the meaning of Section 302 of ERISA and Section 412 of the
Code) has been or could be reasonably expected to be incurred, whether or not
waived, and no excise or other taxes have been or could be reasonably expected
to be incurred or are due and owing with respect to the Benefit Plan because of
any failure to comply with the minimum funding standards of ERISA and the Code;
(iii) the Benefit Plan complies and has been maintained and operated in all
material respects in accordance with its terms and applicable law, including,
without limitation, ERISA and the Code; (iv) no "prohibited transaction", within
the meaning of Section 4975 of the Code and Section 406 of ERISA that has
resulted or could reasonably be expected to result in liability to the Company,
has occurred or is reasonably expected to occur with respect to the Benefit
Plan; (v) no Benefit Plan is or is reasonably expected to be under audit or, to
the Knowledge of the Company, investigation by the IRS, U.S. Department of
Labor, or any other government authority and no such completed audit, if any,
has resulted in the imposition of any Tax or penalty that has not been paid;
(vi) with respect to each Benefit Plan that is funded mostly or partially
through an insurance policy, the Company has no liability in the nature of
retroactive rate adjustment, loss sharing arrangement or other actual or
contingent liability arising wholly or partially out of events occurring on or
before the Effective Time; and (vii) there has not been an adverse change in the
financial condition of any such Benefit Plans covered under Title IV of ERISA
since the date of the latest actuarial report prepared for such plans (copies of
which have been provided to Parent and Purchaser) which would have caused a
material change in the funded status of such plans from the status as of such
date.

                  (i) Except as disclosed on Schedule 3.8(i) annexed hereto, the
consummation of the transactions contemplated by this Agreement will not give
rise to any liability for severance pay, unemployment compensation, termination
pay, or withdrawal liability, or accelerate the time of payment or vesting or
increase the amount of compensation or benefits due to any employee or director
of the Company (whether current, former, or retired) or their beneficiaries
solely by reason of such transactions or by reason of a termination of
employment following such transactions. Except as previously disclosed in
writing by the Company to Parent, no amounts payable under any Benefit Plan will
fail to be deductible for federal income tax purposes by virtue of Section 280G
or 162(m) of the Code. Neither the Company nor any officer or employee thereof,
has made any promise or commitment, whether legally binding or not, to create
any additional plan, agreement, or arrangement, or to modify or change any
existing Benefit Plan. No event, condition or circumstance exists that could
reasonably be expected to result in an increase of the benefits provided under
any Benefit Plan or the expense of maintaining any Benefit Plan from the level
of benefits or expense incurred for the most recent fiscal year ended before the
Effective Time. No event, condition, or circumstance exists that would prevent
the amendment or termination of any Benefit Plan in accordance with its terms
and applicable law. Neither the Company nor any ERISA Affiliate has any unfunded
liabilities

                                      -17-
<PAGE>   24
pursuant to any Benefit Plan that is intended to be an "employee pension benefit
plan" within the meaning of Section 3(2) of ERISA and that is not intended to be
qualified under Section 401(a) of the Code.

         SECTION 3.9 LITIGATION. Except as disclosed in the Company SEC
Documents filed with the SEC prior to the date hereof, there is no suit, action
or proceeding pending or, to the Knowledge of the Company, threatened against
the Company or any of its assets or its officers or directors in their
capacities as such, which individually or in the aggregate with all other such
suits, actions or proceedings is reasonably likely to have a Company Material
Adverse Effect.

         SECTION 3.10 NO DEFAULT; COMPLIANCE WITH APPLICABLE LAWS.

certificates of authority, orders and approvals of, and has made all filings,
applications and registrations with any Governmental Entity that are required in
order to permit it to carry on its business as it is presently conducted, other

all such permits, licenses, certificates of authority, orders and approvals are
now in full force and effect, and, to the Knowledge of Company, no suspension or
cancellation of any of them is threatened, in each case except as would not have
a Company Material Adverse Effect.

                  (b) The execution and delivery of this Agreement, and the
consummation by the Company of the Transactions will not, constitute or result

Incorporation or By-Laws of the Company, (ii) a breach or violation of, or a
default under, any Benefit Plan or any grant or award made under any of the
foregoing, (iii) a breach or violation of, or a default under, the acceleration

regulation or judgment, decree, order, award or governmental or non-governmental
permit or license to which the Company is subject or (iv) any change in the
rights or obligations of any party under any of the contracts described in
clause (ii) or (iv) above, except for such breaches, violations, defaults,
accelerations or changes that would not have a Company Material Adverse Effect.

                  (a) The Company has (i) duly filed (or there has been filed on
their behalf) with the appropriate governmental authorities (x) all federal
income Tax Returns required to be filed by it on or prior to the date hereof and
(y) all other Tax Returns required to be filed by it on or prior to the date

<PAGE>   29
The Company has not engaged in any unfair labor practices within the meaning of
the National Labor Relations Act or similar such legislation of foreign

agreement, judgment, injunction, order or decree binding upon the Company which
materially prohibits or impairs any business or operations of the Company.

         SECTION 3.18 YEAR 2000 COMPLIANCE.

the Company SEC Documents filed as of the date hereof, the computer systems of
the Company which are material to the conduct of the business of the Company

2000 Compliant. The computer systems of the Company have the ability to

Agreement has been duly executed and delivered by Parent and Purchaser, as the
case may be, and, assuming due and valid authorization, execution and delivery
hereof by the Company, is a valid and binding obligation of each of Parent and

of specific performance and injunctive and other forms of equitable relief may
be subject to equitable defenses and to the discretion of the court before which

been obtained, or (iv) violate any order, writ, injunction, decree, statute,
rule or regulation applicable to Parent or Purchaser or any of their properties
or assets, excluding from the foregoing clauses (ii), (iii) or (iv) where the
failure to obtain such permits, authorizations, consents or approvals or to make
such filings, or the existence of such violations, breaches or defaults, would

         SECTION 5.4 NO SOLICITATION.

                  (a) The Company shall not, and shall use its best efforts to
cause its officers, directors, employees and investment bankers, attorneys or
other agents retained by or acting on behalf of the Company not to, (i)
initiate, solicit or encourage (including by way of furnishing non-public
information), directly or indirectly, any inquiries or the making of any
proposal or offer that constitutes or is reasonably likely to lead to any
Acquisition Proposal, (ii) except as permitted by Section 5(b) below, engage in
negotiations or discussions with, or furnish any information or data to any
third party relating to an Acquisition Proposal, or (iii) enter into any
agreement with respect to any Acquisition Proposal or approve any Acquisition
Proposal. The Company will also promptly request each Person that has heretofore
executed a confidentiality agreement in connection with its consideration of an
Acquisition Proposal to return or destroy all non-public information furnished
to such Person by or on behalf of the Company. The Company shall, and shall
cause its directors, officers, employees, financial advisors and other agents or
representatives to, cease immediately and cause to be terminated all activities,
discussions or negotiations, if any, with any Persons conducted heretofore with
respect to any Acquisition Proposal.

                  (b) Notwithstanding Section 5.4(a), the Company and its Board
of Directors and its Representatives (i) may participate in discussions or
negotiations (including, as a part thereof, making any counterproposal) with or
furnish information to any third party (a "Potential Acquirer") making an
unsolicited Acquisition Proposal (which occurred without a breach of Section
5.4(a)) if the Board determines in good faith, upon the advice of its
independent legal counsel, that the failure to participate in such discussions
or negotiations or to furnish such information would be inconsistent with the
Board's fiduciary duties under applicable law, and (ii) shall be permitted to
take and disclose to the Company's stockholders a position with respect to any
tender or exchange offer by a Potential Acquirer, or amend or withdraw such
position, pursuant to Rules 14d-9 and 14e-2 of the Exchange Act, provided that
the Board shall not recommend that the stockholders of the Company tender their
Shares in connection with any such tender or exchange offer unless the Board of
Directors of the Company determines in its good faith judgment, upon the advice
of its independent outside legal counsel, that failing to take such action would
be inconsistent with the Board's fiduciary duties under applicable law.

                  (c) In the event that the Company shall receive any
Acquisition Proposal or the Company has received any request for nonpublic
information relating to the Company or for access to the properties, books or
records of the Company, by any Person that the Company has Knowledge is
considering making, or has made, an Acquisition Proposal, then it shall promptly
inform Parent in writing as to that fact and shall furnish to Parent the
identity of the Potential Acquirer and, if any Acquisition Proposal has been
made, the terms of such Acquisition Proposal (including a copy of any writing
containing such terms submitted by the Potential Acquirer). The Company agrees
not to release any third party from, or waive any provision of, any
confidentiality or standstill agreement to which the Company is a party.
Notwithstanding the foregoing, the Company shall not engage in negotiations
with, or disclose any nonpublic information to, any such Person unless it
receives from such Person an executed confidentiality agreement with terms no
less favorable to the Company than the Confidentiality Agreement entered into
with Parent and Purchaser. The Company will promptly provide to Parent any
non-

                                      -30-

not previously provided to Parent.

modify or propose to withdraw or modify, in any manner adverse to Parent or
Purchaser, the approval or recommendation of such Board of Directors of this
Agreement, the Offer or the Merger, (ii) approve or recommend, or propose to
approve or recommend, any Acquisition Proposal or (iii) enter into any agreement
with respect to any Acquisition Proposal. Notwithstanding the foregoing, the
Company's Board of Directors may withdraw or modify or propose to withdraw or
modify its recommendation of this Agreement, the Offer or the Merger, recommend
or propose to recommend an Acquisition Proposal or terminate this Agreement
pursuant to Section 7.1(e) and thereafter enter into an agreement in connection
with such Acquisition Proposal if, in each case, the Board determines in good
faith, upon the advice of its independent legal counsel, that in order to
comply with its fiduciary duties to the Company's stockholders under applicable
law it is necessary for the Board to withdraw or modify its approval or
recommendation of this Agreement, the Offer or the Merger, approve or recommend
such Acquisition Proposal or terminate this Agreement and enter into another
agreement as described above. The Company shall provide at least five (5)
business days advance notice to Parent to the effect that it is taking such
action.

                  (e) For purposes of this Agreement, "Acquisition Proposal"
shall mean any bona fide offer or proposal, whether in writing or otherwise,
made by a third party or group of third parties to acquire beneficial ownership
(as defined under Rule 13(d) of the Exchange Act) of all or a material portion
of the assets of, or any equity interest in, the Company pursuant to a merger,
consolidation or other business combination, recapitalization, sale of shares of
capital stock, sale of assets, tender offer or exchange offer or similar
transaction involving the Company (other than the transactions contemplated by
this Agreement).

         SECTION 5.5 PUBLICITY. The initial press release with respect to the
execution of this Agreement shall be a joint press release reasonably acceptable

or cause the publication of any press release (or make any written public
statement or verbal statement on a conference call with analysts) with respect
to the Merger, this Agreement or the other transactions contemplated hereby
without notifying in advance the other party, except as may be required by law
or by any listing agreement with a national securities exchange.

         SECTION 5.6 NOTIFICATION OF CERTAIN MATTERS. The Company shall give
prompt notice to Parent and Parent shall give prompt notice to the Company, of
(i) the occurrence, or non-occurrence, of any event the occurrence, or
non-occurrence of which would cause any representation or warranty of such party
contained in this Agreement to be untrue or inaccurate in any material respect
at or prior to the Appointment Date, (ii) any material failure of the Company or
Parent, as the case may be, to comply with or satisfy any covenant or agreement
to be complied with or satisfied by it hereunder, and (iii) the occurrence or
failure to occur of an event or condition that would cause any condition to the
consummation of the Offer or the Merger not to be satisfied. The parties agree
and acknowledge that the delivery of any notice pursuant to this Section 5.6
shall not limit or otherwise affect the remedies available hereunder to the
party receiving such notice.

         SECTION 5.7 DIRECTORS' AND OFFICERS' INSURANCE AND INDEMNIFICATION.

                  (a) From and for a period five (5) years after the Effective
Time, Parent shall cause the Surviving Corporation to indemnify, defend and hold
harmless (and shall also cause the Surviving Corporation to advance expenses as
incurred to the fullest extent permitted under applicable law, to the Company's
Articles of Incorporation and By-Laws and provided that the person to whom
expenses are advanced provides to the Surviving Corporation an undertaking to
repay such advances if it is ultimately determined that such person is not
entitled to indemnification) any person who is now, or has been at any time
prior to the Effective Time, an officer or director of the Company (the
"Indemnified Party") against all losses, claims, damages, liabilities, costs and
expenses (including attorneys' fees and expenses), judgments, fines, losses, and
amounts paid in settlement in connection with any actual or threatened action,
suit, claim, proceeding or investigation (each a "Claim") to the extent that any
such Claim is based on, or arises out of, (i) the fact that such person is or
was a director or officer of the Company or is or was serving at the request of
the Company as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise, or (ii) this Agreement, or any of the
transactions contemplated hereby or thereby, in each case to the extent that any
such Claim pertains to any matter or fact arising, existing, or occurring prior
to or at the Effective Time, regardless of whether such Claim is asserted or
claimed prior to, at or after the Effective Time, to the extent provided in the
Company's Articles of Incorporation or By-Laws in effect at the date hereof,
provided that such indemnification obligations shall be subject to all the
procedures and limitations imposed from time to time by applicable law.

                  (b) From and for a period of five (5) years after the
Effective Time, Parent will maintain or shall cause the Surviving Corporation to
maintain in effect policies of directors' and officers' liability insurance with
reputable and financially sound carriers covering those persons who, as of
immediately prior to the Effective Time, are covered by the Company's directors'
and officers' liability insurance policy (the "Insured Parties ") containing
terms and conditions which are no less advantageous to the Insured Parties than
those that are contained in the Company's directors' and officers' policy
currently in effect; provided, however, that neither Parent nor the Surviving
Corporation shall be required to expend on an annual basis in excess of one
hundred fifty percent (150%) of the annual premium currently paid by the Company
for such coverage (the "Maximum Premium"). If such insurance coverage cannot be
obtained at all, or can only be obtained at an annual premium in excess of the
Maximum Premium, Parent shall, or shall cause the Surviving Corporation to,
maintain the most advantageous policies of directors' and officers' insurance
obtainable for an annual premium equal to the Maximum Premium; provided further,
if such insurance coverage cannot be obtained at all, Parent shall purchase all
available run-off insurance policies with respect to pre-existing insurance in
an amount that, together with all other insurance purchased pursuant to this
Section 5.7(b), does not exceed the Maximum Premium.

         SECTION 5.8 FURTHER ASSURANCES. Subject to the terms and conditions
herein provided, each of the parties hereto agrees to use its respective
reasonable efforts to take, or cause to be taken, all action, and to do, or
cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate and make effective the transactions
contemplated by this Agreement. If at any time after the Closing Date any
further action is necessary or desirable to carry out the purposes of this
Agreement, the parties hereto shall use their respective reasonable efforts to
take or cause to be taken all such necessary action, including, without
limitation, the execution and delivery of such further instruments and documents
as may be reasonably requested by the other party for such purposes or otherwise
to consummate and make effective the transactions contemplated hereby. Subject
to the terms and conditions of this Agreement, Parent and Purchaser agree to use
reasonable efforts to cause the Effective Time to occur as soon as practicable
following consummation of the Offer, subject to compliance with applicable law.

Merger.

         SECTION 5.10 EMPLOYEE MATTERS.

                  Purchaser shall cause the Surviving Corporation to treat
service with the Company prior to the Effective Time by each employee of the
Company in the same manner as service with the Company is treated for
eligibility and vesting purposes (and excluding benefit accrual purposes,
including, without limitation, benefit service under any defined benefit pension
plan) under any benefit plan of Company in which any such employee is eligible
to participate following the Effective Time and which Purchaser elects, in its
sole discretion, to continue or as Purchaser otherwise deems appropriate for any
new benefits established by the Surviving Corporation for the Company's
employees who become employed by the Surviving Corporation; provided, however
that nothing in this Section 5.10 shall obligate Purchaser or the Surviving
Corporation to (i) make any particular benefit plan or benefit available to any
such employee, (ii) continue any particular benefit plan or benefit or (iii)
refrain from terminating or amending any particular benefit plan or benefit.

         SECTION 5.11 TAKEOVER STATUTE. If any "fair price", "moratorium",
"control share acquisition" or other form of anti-takeover statute or regulation
shall become applicable to the transactions contemplated hereby or by the Tender
Agreements, the Company and the members of the Board of Directors of the Company
shall grant such approvals and take such lawful actions as are reasonably
necessary so that the transactions contemplated hereby or thereby may be
consummated as promptly as practicable on the terms contemplated hereby and
otherwise act to eliminate or minimize the effects of such statute or regulation
on the transactions contemplated hereby and the Company, Parent and Purchaser
shall, without limiting the generality of any of the foregoing, satisfy the
respective obligations imposed on them by virtue of Section 910 of the MBCA.

         SECTION 5.12 SECTION 338 ELECTION. No election shall be made (or deemed
made) under Section 338(g) or Section 338(h)(10) of the Code with respect to the

hereby, by written agreement of the parties hereto (which in the case of the
Company shall require approval of its Board of Directors and include approvals

                                R E C I T A L S :

         A. Parent, Purchaser and Company have entered into an Agreement and
Plan of Merger dated this date (the "Merger Agreement") whereby Purchaser has

shares of the issued and outstanding Company common stock, par value $1.00 per
share (the "Shares"), at a price of $11.75 per Share, net to the seller in cash
(such price, or such higher price per Share as Purchaser may indicate in the
Offer being referred to herein as the "Offer Price"), subject to the conditions
set forth in the Merger Agreement.

         B. Parent and Purchaser have agreed to deposit with the Escrow Agent,
in escrow, an amount equal to the product of the Offer Price ($11.75) and the
number of Shares outstanding (1,388,291) or $16,312,419 which, together with
such sums as Parent and Purchaser may subsequently deposit to reflect any
increase in the Offer Price, shall be referred to as the "Escrow Fund".

         C. The Escrow Agent is willing to accept the Escrow Fund on the terms
hereinafter set forth.
<PAGE>   52
         NOW, THEREFORE, in consideration of the premises and the mutual
covenants hereinafter set forth, the parties agree as follows:

         1. ESCROW FUND. Parent and Purchaser hereby deposit the Escrow Fund
with Escrow Agent, in escrow, and Escrow Agent hereby accepts the Escrow Fund,
acknowledges receipt of $16,312,419.00 and agrees to hold and disburse the same
in accordance with the terms of this Escrow Agreement.

         2.       INITIAL RELEASE OF ESCROW FUND.

                  (a) Parent, Purchaser and Company agree that when the Minimum
Condition of the Offer and the other conditions to the Offer set forth in Annex
A of the Merger Agreement have been fulfilled and/or waived by Purchaser, they
shall jointly execute and deliver to the Escrow Agent a written authorization
and direction ("Instruction") that the Escrow Agent transfer from the Escrow
Fund to the Account hereinafter designated the amount indicated by them, being
the product of the Offer Price and the number of Shares which have been validly
tendered, not withdrawn and accepted by Parent and Purchaser as provided in the
Offer.

                  (b) Escrow Agent agrees, upon receipt of such Instruction,
promptly to transmit by wire transfer from the Escrow Fund to the Account the
sum set forth in the Instruction.

                  (c) The Account to which funds shall be transferred by the
Escrow Agent under this Section 2 is as follows:

                  Company, Purchaser and Parent understand and agree that under
Uniform Commercial Code Article 4A, all banks executing the above wire

Purchaser and Parent represent and warrant that they have used extraordinary
care to verify that the numbers set forth above are correct. The Escrow Agent's
acceptance of such wire transfer instructions shall be binding on all parties
and the Escrow Agent will not be liable for any cost, expense or loss arising
out of such transactions.

         3.       FURTHER RELEASE OF ESCROW FUND.

                  (a) Company agrees that, upon request of Parent and Purchaser,
whenever Purchaser accepts additional Shares tendered pursuant to the Offer
beyond those required to meet the Minimum Condition under the Merger Agreement,
Company will join with Parent and Purchaser in providing joint Instruction to
the Escrow Agent to transfer additional amounts from the Escrow Fund to the
Account, such amounts to be equal to the product of the Offer Price and the
number of additional tendered Shares accepted by Purchaser.

                  (b) The Escrow Agent agrees, upon receipt of such Instruction,
promptly to transmit by wire transfer from the Escrow Fund to the Account the
additional amounts set forth in the Instruction.

         4. RELEASE OF ESCROW FUNDS UPON MERGER. Company, Parent and Purchaser
agree that upon merger of Company and Purchaser, with Purchaser or Company as
survivor, and whether a short-form merger under Section 904 of the Maine
Business Corporation Act ("MBCA") or a merger approved at a meeting of
stockholders of the Company, Company and Purchaser shall promptly present to
Escrow Agent their joint Instruction (or the surviving corporation under the
merger shall give its Instruction) to transmit by wire transfer from the


                                      -3-
<PAGE>   54
Escrow Fund to the Account a specified amount. Company and Purchaser agree the
amount shall be equal to the product of the Offer Price and the remaining issued
and outstanding Shares of the Company which were not previously accepted by
Purchaser, less any Demanding Shares or Dissenting Shares (as defined in the
Merger Agreement). The Escrow Agent agrees, upon receipt of such Instruction,
promptly to transmit by wire transfer from the Escrow Fund to the Account the
amount set forth in such Instruction. It is agreed by the Parent, Purchaser and
Company that any amounts to be paid to holders of Demanding Common Stock or
Dissenting Common Stock shall be paid from the Escrow Fund, including such
additional funds as shall be required to be deposited by Parent and Purchaser to
satisfy the applicable provisions of Sections 910 and 909 of the MCBA. However,
Instruction to the Escrow Agent for disbursement of any such amounts shall be
signed only by Parent and shall certify that the amount is for payment of
Demanding Common Stock or Dissenting Common Stock. Parent shall send a copy of
the Instruction to the Company at the same time it sends the Instruction to the
Escrow Agent. The Escrow Agent agrees, upon receipt of such Instruction from
Parent, promptly to transmit by wire transfer from the Escrow Fund to the
Account the amount set forth in such Instruction.

         5. RELEASE OF ESCROW FUNDS UPON TERMINATION OF TENDER OFFER OR MERGER
AGREEMENT. In the event that (1) Parent or Purchaser terminates the Offer or (2)
Company terminates the Merger Agreement, Parent shall give written notice to the
Escrow Agent to pay over to Purchaser all funds, together with earnings thereon,
then remaining in the Escrow Account ("Release Notice"). Upon receipt of the
Release Notice, Escrow Agent shall pay over such amounts according to the
instructions set forth in the Release Notice. Parent shall send to the Company a
copy of any Release Notice at the same time it is given to the Escrow Agent.

         6. INVESTMENT OF ESCROW FUND. Escrow Agent may invest the Escrow Funds
if so directed by Parent in obligations of the United States government or any
agency or


                                      -4-

instrumentality thereof, or in obligations that are guaranteed or insured by the
United States government or any agency or instrumentality thereof. Any net
profit resulting from, or interest or income produced by such investments shall
be payable to Parent or Purchaser on written Instruction given by Parent.

         Escrow Agent shall send to Parent a monthly statement showing the
investments in which the Escrow Fund is invested ("Escrow Fund Investments"),
the purchase price of investments purchased during the statement period and the
market value of Escrow Fund Investments as of the end of the statement period.
Parent shall review such statements and determine whether the market value of
Escrow Fund Investments is sufficient to enable the Escrow Fund to satisfy all
remaining obligations originally contemplated to be paid out of the Escrow Fund.
In the event that the Escrow Fund shall not be sufficient to satisfy all
remaining obligations originally contemplated to be paid out of the Escrow Fund,
Parent shall promptly thereafter deposit in such Escrow Fund cash in an amount
sufficient to enable such Escrow Fund to satisfy all remaining obligations
originally contemplated to be paid out of such Escrow Fund.

         7. FEE OF ESCROW AGENT. For its services hereunder, Escrow Agent shall
receive the fees set forth on the fee schedule attached hereto as Exhibit A.
Parent and Purchaser shall be solely responsible for payment of Escrow Agent's
fee hereunder and Escrow Agent shall have no claim whatsoever on the Escrow
Fund. Parent may, in its sole discretion, authorize Escrow Agent's fees to be
paid from any interest or other earnings on the Escrow Fund, but not from any
amounts deposited by Parent or Purchaser to the Escrow Fund.

         8.       LIABILITY OF ESCROW AGENT.

                  (a) Escrow Agent may act in reliance upon any writing or
instrument or signature which it, in good faith, believes to be genuine, may
assume the validity and accuracy of any statements or assertion contained in
such writing or instrument, and may assume that any

person purporting to give any writing, notice, advice or instruction in
connection with the provisions hereof has been duly authorized to do so. Escrow
Agent shall not be liable in any manner for the sufficiency or correctness as to
form, manner of execution, or validity of any written instructions delivered to
it; nor as to the identity, authority, or rights of any person executing the
same and shall otherwise not be liable for any mistakes of fact or error of
judgment, or for any acts or omissions of any kind unless caused by its willful
misconduct or gross negligence. The Escrow Agent shall be fully protected in
acting without inquiry in accordance with such written instruction, including by
way of example, and not as a limitation, without inquiry as to purposes for
which amounts disbursed from the Escrow Fund are expended, or whether the party
giving the written instruction has given a copy or other notice of such
instruction to any other party. The Escrow Agent shall not be liable for any
loss or diminution in value of the Escrow Fund as a result of the investment of
the Escrow Fund, nor shall it be responsible if the Escrow Fund is not
sufficient to make intended payments. The Escrow Agent shall have no duty to
calculate or verify any amounts required to be transferred to the Account or
otherwise disbursed from the Escrow Fund.

                  (b) It is agreed that the duties of Escrow Agent are purely

Escrow Fund and for the disposition of same in accordance with this Escrow
Agreement and any costs, expenses or fees incurred by the Escrow Agent in the
performance of these duties (except as described in the next sentence or in
Section 9) shall be borne by Parent and Purchaser. Each of Company, Parent and
Purchaser hereby agrees to indemnify, defend and hold Escrow Agent harmless from
and against any and all claims, liabilities, damages, costs, penalties, losses,
actions, suits or proceedings at law or in equity, or any other expenses, fees
or charges of any character or nature (including, without limitation, attorneys'
fees, paralegals' fees and costs incurred in all trial and appellate


                                      -6-

proceedings or otherwise if no litigation is instituted) which it may incur or
with which it may be threatened directly or indirectly arising from or in any
way connected with this Escrow Agreement, whether or not such claims,
liabilities, damages, costs, penalties, losses, actions, suits or proceedings
arise from or are in any way connected with any negligence of Escrow Agent.
Notwithstanding anything in this subparagraph (b) to the contrary, in no event
shall Escrow Agent be absolved from any liability arising from Escrow Agent's
gross negligence or willful misconduct.

affected third parties of whom Escrow Agent has received actual notice, Escrow
Agent shall be released and relieved from any and all further obligation and
liability hereunder or in connection herewith and Company, Parent and Purchaser
hereby, jointly and severally, agree to indemnify, defend and hold Escrow Agent
harmless from and against all costs, expenses, damages or losses arising in
connection therewith, including, but not limited to, all costs and expenses
incurred by Escrow Agent in connection with the filing of


                                      -7-
<PAGE>   58
such action, including, but not limited to, attorneys' and paralegals' fees and
court costs at all trial and appellate levels.

         10.      REMOVAL AND RESIGNATION OF ESCROW AGENT.

                  (a) Company, Parent and Purchaser may, upon written notice to

                    (g) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without affecting the
validity or enforceability of the remaining provisions hereof. Any such
prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction. If any provision
of this Agreement is so broad as to be unenforceable, the provision shall be
interpreted to be only so broad as is enforceable, provided the commercial
objective of this Agreement is not frustrated.

                  (h) Each of the parties hereto acknowledges and agrees that in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached, each
non-breaching party would be irreparably and immediately harmed and could not be
made whole by monetary damages. Accordingly, it is agreed that the parties
hereto (i) shall be entitled to an injunction or injunctions to prevent breaches
of this Agreement and to compel specific performance of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity, and (ii) will waive, in any proceeding for specific performance, the
defense of adequacy of a remedy at law. Each of the parties further agrees to
waive any requirement for the securing or posting of any bond or other security
in connection with any proceeding for specific performance.

                  (i) All rights, powers and remedies provided under this
Agreement or otherwise available in respect hereof at law or in equity shall be
cumulative and not alternative, and the exercise of any thereof by any party
shall not preclude the simultaneous or later exercise of any other such right,
power or remedy by such party. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

                  (j) This Agreement shall be governed and construed in
accordance with the Maine Business Corporations Act (the "MBCA"), where
applicable, and otherwise with the laws of the State of New York without giving
effect to the principles of conflicts of law thereof or of any other
jurisdiction.

                  (k) This Agreement may be executed in counterparts, each of
which shall be deemed to be an original, but all of which, taken together, shall
constitute one and the same instrument. This Agreement may be executed by
facsimile signatures and such signature shall be deemed binding for all purposes
hereof, without delivery of an original signature being thereafter required.

                  (l) Any legal action or proceeding with respect to this

of or in connection with this Agreement or otherwise brought in the courts

judgment, execution of judgment or otherwise), (iii) that the proceeding in any
such court is brought in an inconvenient forum, (iv) that the venue of such
proceeding is improper or (v) that this Agreement, or the subject matter hereof,
may not be enforced in or by such court. Nothing herein shall affect the right
of any party hereto to serve process in any other manner permitted by law.

Stock into the Offer which have been accepted for payment and purchased by
Purchaser in the Offer (the "Offer Price"), but not any additional amounts paid
or payable to holders of Company Common Stock that do not participate in the

                          Attention:  Gerald E. Rudman, Esq.

                  (g) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent


                                      -7-
<PAGE>   8
of such prohibition or unenforceability without affecting the validity or
enforceability of the remaining provisions hereof. Any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable, provided the commercial objective of this
Agreement is not frustrated.

                  (h) Each of the parties hereto acknowledges and agrees that in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached, each
non-breaching party would be irreparably and immediately harmed and could not be
made whole by monetary damages. Accordingly, it is agreed that the parties
hereto (i) shall be entitled to an injunction or injunctions to prevent breaches
of this Agreement and to compel specific performance of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity, and (ii) will waive, in any proceeding for specific performance, the
defense of adequacy of a remedy at law. Each of the parties further agrees to
waive any requirement for the securing or posting of any bond or other security
in connection with any proceeding for specific performance.

                  (i) All rights, powers and remedies provided under this
Agreement or otherwise available in respect hereof at law or in equity shall be
cumulative and not alternative, and the exercise of any thereof by any party
shall not preclude the simultaneous or later exercise of any other such right,
power or remedy by such party. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

                  (j) This Agreement shall be governed and construed in
accordance with the Maine Business Corporations Act (the "MBCA"), where
applicable, and otherwise with the laws of the State of New York without giving
effect to the principles of conflicts of law thereof or of any other
jurisdiction.

                  (k) This Agreement may be executed in counterparts, each of
which shall be deemed to be an original, but all of which, taken together, shall
constitute one and the same instrument. This Agreement may be executed by
facsimile signatures and such signature shall be deemed binding for all purposes
hereof, without delivery of an original signature being thereafter required.

                  (l) Any legal action or proceeding with respect to this
Agreement or any matters arising out of or in connection with this Agreement or
otherwise, and any action for enforcement of any judgment in respect thereof
shall be brought exclusively in the courts of the State of New York or of the
United States of America for the Western District of New York or the state or
federal courts located in the State of Maine, to the


                                      -8-
<PAGE>   9
extent the proceeding involves an interpretation or enforcement of the MBCA,
and, by execution and delivery of this Agreement, each of the Tendering
Stockholder, Parent and Purchaser each hereby accept for themselves and in
respect of their respective property, generally and unconditionally, the
exclusive jurisdiction of the aforesaid courts and appellate courts thereof.
Each of the Stockholder, Parent and Purchaser irrevocably consents to service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, or by recognized international express carrier or delivery service, to
any Stockholder at the address referred to in Section 11(f).

                  (m) Each of the Stockholder, Parent and Purchaser each hereby
irrevocably waives any objection which he or she may now or hereafter have to

                          Attention:  Gerald E. Rudman, Esq.

                  (g) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent


                                      -7-
<PAGE>   8
of such prohibition or unenforceability without affecting the validity or
enforceability of the remaining provisions hereof. Any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable, provided the commercial objective of this
Agreement is not frustrated.

                  (h) Each of the parties hereto acknowledges and agrees that in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached, each
non-breaching party would be irreparably and immediately harmed and could not be
made whole by monetary damages. Accordingly, it is agreed that the parties
hereto (i) shall be entitled to an injunction or injunctions to prevent breaches
of this Agreement and to compel specific performance of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity, and (ii) will waive, in any proceeding for specific performance, the
defense of adequacy of a remedy at law. Each of the parties further agrees to
waive any requirement for the securing or posting of any bond or other security
in connection with any proceeding for specific performance.

                  (i) All rights, powers and remedies provided under this
Agreement or otherwise available in respect hereof at law or in equity shall be
cumulative and not alternative, and the exercise of any thereof by any party
shall not preclude the simultaneous or later exercise of any other such right,
power or remedy by such party. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

                  (j) This Agreement shall be governed and construed in
accordance with the Maine Business Corporations Act (the "MBCA"), where
applicable, and otherwise with the laws of the State of New York without giving
effect to the principles of conflicts of law thereof or of any other
jurisdiction.

                  (k) This Agreement may be executed in counterparts, each of
which shall be deemed to be an original, but all of which, taken together, shall
constitute one and the same instrument. This Agreement may be executed by
facsimile signatures and such signature shall be deemed binding for all purposes
hereof, without delivery of an original signature being thereafter required.

                  (l) Any legal action or proceeding with respect to this
Agreement or any matters arising out of or in connection with this Agreement or
otherwise, and any action for enforcement of any judgment in respect thereof
shall be brought exclusively in the courts of the State of New York or of the
United States of America for the Western District of New York or the state or
federal courts located in the State of Maine, to the


                                      -8-
<PAGE>   9
extent the proceeding involves an interpretation or enforcement of the MBCA,
and, by execution and delivery of this Agreement, each of the Tendering
Stockholder, Parent and Purchaser each hereby accept for themselves and in
respect of their respective property, generally and unconditionally, the
exclusive jurisdiction of the aforesaid courts and appellate courts thereof.
Each of the Stockholder, Parent and Purchaser irrevocably consents to service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, or by recognized international express carrier or delivery service, to
any Stockholder at the address referred to in Section 11(f).

                  (m) Each of the Stockholder, Parent and Purchaser each hereby
irrevocably waives any objection which he or she may now or hereafter have to
the laying of venue of any of the aforesaid actions or proceedings arising out
of or in connection with this Agreement or otherwise brought in the courts
referred to above and hereby further irrevocably waives and agrees, to the
extent permitted by applicable law, not to plead or claim in any such court, by
way of motion, as a defense, counterclaim or otherwise, in any action or
proceeding with respect to this Agreement, (i) any claim that he or she is not
personally subject to the jurisdiction of the above-named courts, (ii) that he
or she or his or her property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through
service of notice, attachment before judgment, attachment in aid of execution of
judgment, execution of judgment or otherwise), (iii) that the proceeding in any
such court is brought in an inconvenient forum, (iv) that the venue of such
proceeding is improper or (v) that this Agreement, or the subject matter hereof,
may not be enforced in or by such court. Nothing herein shall affect the right
of any party hereto to serve process in any other manner permitted by law.

         IN WITNESS WHEREOF, Parent, Purchaser and the Stockholders have caused
this Agreement to be duly executed as of the day and year first above written.

Parent or Purchaser, the consummation by Parent or Purchaser of the transactions
contemplated hereby or compliance by Parent or Purchaser with any of the

cancellation, material modification or acceleration) under any of the terms,
conditions or provisions of any note, loan agreement, bond, mortgage, indenture,

<PAGE>   4
Stock into the Offer which have been accepted for payment and purchased by
Purchaser in the Offer (the "Offer Price"), but not any additional amounts paid
or payable to holders of Company Common Stock that do not participate in the
Offer by reason of rights of appraisal, rights of dissent or otherwise. The
Stockholder agrees not to withdraw any of its Owned Shares unless the Offer is
terminated or has expired without Purchaser having accepted for payment all of
the Shares tendered in the Offer.

                          84 Harlow Street
                          Bangor, Maine  04401
                          Attention:  Gerald E. Rudman, Esq.

                  (g) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent


                                      -7-
<PAGE>   8
of such prohibition or unenforceability without affecting the validity or
enforceability of the remaining provisions hereof. Any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable, provided the commercial objective of this
Agreement is not frustrated.

                  (h) Each of the parties hereto acknowledges and agrees that in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached, each
non-breaching party would be irreparably and immediately harmed and could not be
made whole by monetary damages. Accordingly, it is agreed that the parties
hereto (i) shall be entitled to an injunction or injunctions to prevent breaches
of this Agreement and to compel specific performance of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity, and (ii) will waive, in any proceeding for specific performance, the
defense of adequacy of a remedy at law. Each of the parties further agrees to
waive any requirement for the securing or posting of any bond or other security
in connection with any proceeding for specific performance.

                  (i) All rights, powers and remedies provided under this
Agreement or otherwise available in respect hereof at law or in equity shall be
cumulative and not alternative, and the exercise of any thereof by any party
shall not preclude the simultaneous or later exercise of any other such right,
power or remedy by such party. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

                  (j) This Agreement shall be governed and construed in
accordance with the Maine Business Corporations Act (the "MBCA"), where
applicable, and otherwise with the laws of the State of New York without giving
effect to the principles of conflicts of law thereof or of any other
jurisdiction.

                  (k) This Agreement may be executed in counterparts, each of
which shall be deemed to be an original, but all of which, taken together, shall
constitute one and the same instrument. This Agreement may be executed by
facsimile signatures and such signature shall be deemed binding for all purposes
hereof, without delivery of an original signature being thereafter required.

                  (l) Any legal action or proceeding with respect to this
Agreement or any matters arising out of or in connection with this Agreement or
otherwise, and any action for enforcement of any judgment in respect thereof
shall be brought exclusively in the courts of the State of New York or of the
United States of America for the Western District of New York or the state or
federal courts located in the State of Maine, to the


                                      -8-
<PAGE>   9
extent the proceeding involves an interpretation or enforcement of the MBCA,
and, by execution and delivery of this Agreement, each of the Tendering
Stockholder, Parent and Purchaser each hereby accept for themselves and in
respect of their respective property, generally and unconditionally, the
exclusive jurisdiction of the aforesaid courts and appellate courts thereof.
Each of the Stockholder, Parent and Purchaser irrevocably consents to service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, or by recognized international express carrier or delivery service, to
any Stockholder at the address referred to in Section 11(f).

                  (m) Each of the Stockholder, Parent and Purchaser each hereby
irrevocably waives any objection which he or she may now or hereafter have to
the laying of venue of any of the aforesaid actions or proceedings arising out
of or in connection with this Agreement or otherwise brought in the courts
referred to above and hereby further irrevocably waives and agrees, to the
extent permitted by applicable law, not to plead or claim in any such court, by
way of motion, as a defense, counterclaim or otherwise, in any action or
proceeding with respect to this Agreement, (i) any claim that he or she is not
personally subject to the jurisdiction of the above-named courts, (ii) that he
or she or his or her property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through
service of notice, attachment before judgment, attachment in aid of execution of
judgment, execution of judgment or otherwise), (iii) that the proceeding in any
such court is brought in an inconvenient forum, (iv) that the venue of such
proceeding is improper or (v) that this Agreement, or the subject matter hereof,
may not be enforced in or by such court. Nothing herein shall affect the right
of any party hereto to serve process in any other manner permitted by law.

         IN WITNESS WHEREOF, Parent, Purchaser and the Stockholders have caused
this Agreement to be duly executed as of the day and year first above written.

Stock into the Offer which have been accepted for payment and purchased by
Purchaser in the Offer (the "Offer Price"), but not any additional amounts paid
or payable to holders of Company Common Stock that do not participate in the

                          84 Harlow Street

                          Attention:  Gerald E. Rudman, Esq.

                  (g) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent


                                      -7-
<PAGE>   8
of such prohibition or unenforceability without affecting the validity or
enforceability of the remaining provisions hereof. Any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable, provided the commercial objective of this
Agreement is not frustrated.

                  (h) Each of the parties hereto acknowledges and agrees that in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached, each
non-breaching party would be irreparably and immediately harmed and could not be
made whole by monetary damages. Accordingly, it is agreed that the parties
hereto (i) shall be entitled to an injunction or injunctions to prevent breaches
of this Agreement and to compel specific performance of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity, and (ii) will waive, in any proceeding for specific performance, the
defense of adequacy of a remedy at law. Each of the parties further agrees to
waive any requirement for the securing or posting of any bond or other security
in connection with any proceeding for specific performance.

                  (i) All rights, powers and remedies provided under this
Agreement or otherwise available in respect hereof at law or in equity shall be
cumulative and not alternative, and the exercise of any thereof by any party
shall not preclude the simultaneous or later exercise of any other such right,
power or remedy by such party. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

                  (j) This Agreement shall be governed and construed in
accordance with the Maine Business Corporations Act (the "MBCA"), where
applicable, and otherwise with the laws of the State of New York without giving
effect to the principles of conflicts of law thereof or of any other
jurisdiction.

                  (k) This Agreement may be executed in counterparts, each of
which shall be deemed to be an original, but all of which, taken together, shall
constitute one and the same instrument. This Agreement may be executed by
facsimile signatures and such signature shall be deemed binding for all purposes
hereof, without delivery of an original signature being thereafter required.

                  (l) Any legal action or proceeding with respect to this
Agreement or any matters arising out of or in connection with this Agreement or
otherwise, and any action for enforcement of any judgment in respect thereof
shall be brought exclusively in the courts of the State of New York or of the
United States of America for the Western District of New York or the state or
federal courts located in the State of Maine, to the


                                      -8-
<PAGE>   9
extent the proceeding involves an interpretation or enforcement of the MBCA,
and, by execution and delivery of this Agreement, each of the Tendering
Stockholder, Parent and Purchaser each hereby accept for themselves and in
respect of their respective property, generally and unconditionally, the
exclusive jurisdiction of the aforesaid courts and appellate courts thereof.
Each of the Stockholder, Parent and Purchaser irrevocably consents to service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, or by recognized international express carrier or delivery service, to
any Stockholder at the address referred to in Section 11(f).

                  (m) Each of the Stockholder, Parent and Purchaser each hereby
irrevocably waives any objection which he or she may now or hereafter have to
the laying of venue of any of the aforesaid actions or proceedings arising out
of or in connection with this Agreement or otherwise brought in the courts
referred to above and hereby further irrevocably waives and agrees, to the
extent permitted by applicable law, not to plead or claim in any such court, by
way of motion, as a defense, counterclaim or otherwise, in any action or
proceeding with respect to this Agreement, (i) any claim that he or she is not
personally subject to the jurisdiction of the above-named courts, (ii) that he
or she or his or her property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through
service of notice, attachment before judgment, attachment in aid of execution of
judgment, execution of judgment or otherwise), (iii) that the proceeding in any
such court is brought in an inconvenient forum, (iv) that the venue of such
proceeding is improper or (v) that this Agreement, or the subject matter hereof,
may not be enforced in or by such court. Nothing herein shall affect the right
of any party hereto to serve process in any other manner permitted by law.

         IN WITNESS WHEREOF, Parent, Purchaser and the Stockholders have caused
this Agreement to be duly executed as of the day and year first above written.

Stock into the Offer which have been accepted for payment and purchased by
Purchaser in the Offer (the "Offer Price"), but not any additional amounts paid

                          Attention:  Gerald E. Rudman, Esq.

                  (g) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent


                                      -7-
<PAGE>   8
of such prohibition or unenforceability without affecting the validity or
enforceability of the remaining provisions hereof. Any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable, provided the commercial objective of this
Agreement is not frustrated.

                  (h) Each of the parties hereto acknowledges and agrees that in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached, each
non-breaching party would be irreparably and immediately harmed and could not be
made whole by monetary damages. Accordingly, it is agreed that the parties
hereto (i) shall be entitled to an injunction or injunctions to prevent breaches
of this Agreement and to compel specific performance of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity, and (ii) will waive, in any proceeding for specific performance, the
defense of adequacy of a remedy at law. Each of the parties further agrees to
waive any requirement for the securing or posting of any bond or other security
in connection with any proceeding for specific performance.

                  (i) All rights, powers and remedies provided under this
Agreement or otherwise available in respect hereof at law or in equity shall be
cumulative and not alternative, and the exercise of any thereof by any party
shall not preclude the simultaneous or later exercise of any other such right,
power or remedy by such party. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

                  (j) This Agreement shall be governed and construed in
accordance with the Maine Business Corporations Act (the "MBCA"), where
applicable, and otherwise with the laws of the State of New York without giving
effect to the principles of conflicts of law thereof or of any other
jurisdiction.

                  (k) This Agreement may be executed in counterparts, each of
which shall be deemed to be an original, but all of which, taken together, shall
constitute one and the same instrument. This Agreement may be executed by
facsimile signatures and such signature shall be deemed binding for all purposes
hereof, without delivery of an original signature being thereafter required.

                  (l) Any legal action or proceeding with respect to this
Agreement or any matters arising out of or in connection with this Agreement or
otherwise, and any action for enforcement of any judgment in respect thereof
shall be brought exclusively in the courts of the State of New York or of the
United States of America for the Western District of New York or the state or
federal courts located in the State of Maine, to the


                                      -8-
<PAGE>   9
extent the proceeding involves an interpretation or enforcement of the MBCA,
and, by execution and delivery of this Agreement, each of the Tendering
Stockholder, Parent and Purchaser each hereby accept for themselves and in
respect of their respective property, generally and unconditionally, the
exclusive jurisdiction of the aforesaid courts and appellate courts thereof.
Each of the Stockholder, Parent and Purchaser irrevocably consents to service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, or by recognized international express carrier or delivery service, to
any Stockholder at the address referred to in Section 11(f).

                  (m) Each of the Stockholder, Parent and Purchaser each hereby
irrevocably waives any objection which he or she may now or hereafter have to
the laying of venue of any of the aforesaid actions or proceedings arising out
of or in connection with this Agreement or otherwise brought in the courts
referred to above and hereby further irrevocably waives and agrees, to the
extent permitted by applicable law, not to plead or claim in any such court, by
way of motion, as a defense, counterclaim or otherwise, in any action or
proceeding with respect to this Agreement, (i) any claim that he or she is not
personally subject to the jurisdiction of the above-named courts, (ii) that he
or she or his or her property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through
service of notice, attachment before judgment, attachment in aid of execution of
judgment, execution of judgment or otherwise), (iii) that the proceeding in any
such court is brought in an inconvenient forum, (iv) that the venue of such
proceeding is improper or (v) that this Agreement, or the subject matter hereof,
may not be enforced in or by such court. Nothing herein shall affect the right
of any party hereto to serve process in any other manner permitted by law.

         IN WITNESS WHEREOF, Parent, Purchaser and the Stockholders have caused
this Agreement to be duly executed as of the day and year first above written.

                          Attention:  Gerald E. Rudman, Esq.

                  (g) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent


                                      -7-
<PAGE>   8
of such prohibition or unenforceability without affecting the validity or
enforceability of the remaining provisions hereof. Any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable, provided the commercial objective of this
Agreement is not frustrated.

                  (h) Each of the parties hereto acknowledges and agrees that in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached, each
non-breaching party would be irreparably and immediately harmed and could not be
made whole by monetary damages. Accordingly, it is agreed that the parties
hereto (i) shall be entitled to an injunction or injunctions to prevent breaches
of this Agreement and to compel specific performance of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity, and (ii) will waive, in any proceeding for specific performance, the
defense of adequacy of a remedy at law. Each of the parties further agrees to
waive any requirement for the securing or posting of any bond or other security
in connection with any proceeding for specific performance.

                  (i) All rights, powers and remedies provided under this
Agreement or otherwise available in respect hereof at law or in equity shall be
cumulative and not alternative, and the exercise of any thereof by any party
shall not preclude the simultaneous or later exercise of any other such right,
power or remedy by such party. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

                  (j) This Agreement shall be governed and construed in
accordance with the Maine Business Corporations Act (the "MBCA"), where
applicable, and otherwise with the laws of the State of New York without giving
effect to the principles of conflicts of law thereof or of any other
jurisdiction.

                  (k) This Agreement may be executed in counterparts, each of
which shall be deemed to be an original, but all of which, taken together, shall
constitute one and the same instrument. This Agreement may be executed by
facsimile signatures and such signature shall be deemed binding for all purposes
hereof, without delivery of an original signature being thereafter required.

                  (l) Any legal action or proceeding with respect to this
Agreement or any matters arising out of or in connection with this Agreement or
otherwise, and any action for enforcement of any judgment in respect thereof
shall be brought exclusively in the courts of the State of New York or of the
United States of America for the Western District of New York or the state or
federal courts located in the State of Maine, to the


                                      -8-
<PAGE>   9
extent the proceeding involves an interpretation or enforcement of the MBCA,
and, by execution and delivery of this Agreement, each of the Tendering
Stockholder, Parent and Purchaser each hereby accept for themselves and in
respect of their respective property, generally and unconditionally, the
exclusive jurisdiction of the aforesaid courts and appellate courts thereof.
Each of the Stockholder, Parent and Purchaser irrevocably consents to service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, or by recognized international express carrier or delivery service, to
any Stockholder at the address referred to in Section 11(f).

                  (m) Each of the Stockholder, Parent and Purchaser each hereby
irrevocably waives any objection which he or she may now or hereafter have to
the laying of venue of any of the aforesaid actions or proceedings arising out
of or in connection with this Agreement or otherwise brought in the courts
referred to above and hereby further irrevocably waives and agrees, to the
extent permitted by applicable law, not to plead or claim in any such court, by
way of motion, as a defense, counterclaim or otherwise, in any action or
proceeding with respect to this Agreement, (i) any claim that he or she is not
personally subject to the jurisdiction of the above-named courts, (ii) that he
or she or his or her property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through
service of notice, attachment before judgment, attachment in aid of execution of
judgment, execution of judgment or otherwise), (iii) that the proceeding in any
such court is brought in an inconvenient forum, (iv) that the venue of such
proceeding is improper or (v) that this Agreement, or the subject matter hereof,
may not be enforced in or by such court. Nothing herein shall affect the right
of any party hereto to serve process in any other manner permitted by law.

         IN WITNESS WHEREOF, Parent, Purchaser and the Stockholders have caused
this Agreement to be duly executed as of the day and year first above written.

                          Attention:  Gerald E. Rudman, Esq.

                  (g) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent


                                      -7-
<PAGE>   8
of such prohibition or unenforceability without affecting the validity or
enforceability of the remaining provisions hereof. Any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable, provided the commercial objective of this
Agreement is not frustrated.

                  (h) Each of the parties hereto acknowledges and agrees that in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached, each
non-breaching party would be irreparably and immediately harmed and could not be
made whole by monetary damages. Accordingly, it is agreed that the parties
hereto (i) shall be entitled to an injunction or injunctions to prevent breaches
of this Agreement and to compel specific performance of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity, and (ii) will waive, in any proceeding for specific performance, the
defense of adequacy of a remedy at law. Each of the parties further agrees to
waive any requirement for the securing or posting of any bond or other security
in connection with any proceeding for specific performance.

Agreement or otherwise available in respect hereof at law or in equity shall be
cumulative and not alternative, and the exercise of any thereof by any party
shall not preclude the simultaneous or later exercise of any other such right,
power or remedy by such party. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

                  (j) This Agreement shall be governed and construed in
accordance with the Maine Business Corporations Act (the "MBCA"), where
applicable, and otherwise with the laws of the State of New York without giving
effect to the principles of conflicts of law thereof or of any other
jurisdiction.

                  (k) This Agreement may be executed in counterparts, each of
which shall be deemed to be an original, but all of which, taken together, shall
constitute one and the same instrument. This Agreement may be executed by
facsimile signatures and such signature shall be deemed binding for all purposes
hereof, without delivery of an original signature being thereafter required.

                  (l) Any legal action or proceeding with respect to this
Agreement or any matters arising out of or in connection with this Agreement or
otherwise, and any action for enforcement of any judgment in respect thereof
shall be brought exclusively in the courts of the State of New York or of the
United States of America for the Western District of New York or the state or
federal courts located in the State of Maine, to the


                                      -8-
<PAGE>   9
extent the proceeding involves an interpretation or enforcement of the MBCA,
and, by execution and delivery of this Agreement, each of the Tendering
Stockholder, Parent and Purchaser each hereby accept for themselves and in
respect of their respective property, generally and unconditionally, the
exclusive jurisdiction of the aforesaid courts and appellate courts thereof.
Each of the Stockholder, Parent and Purchaser irrevocably consents to service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, or by recognized international express carrier or delivery service, to
any Stockholder at the address referred to in Section 11(f).

                  (m) Each of the Stockholder, Parent and Purchaser each hereby
irrevocably waives any objection which he or she may now or hereafter have to
the laying of venue of any of the aforesaid actions or proceedings arising out
of or in connection with this Agreement or otherwise brought in the courts
referred to above and hereby further irrevocably waives and agrees, to the
extent permitted by applicable law, not to plead or claim in any such court, by
way of motion, as a defense, counterclaim or otherwise, in any action or
proceeding with respect to this Agreement, (i) any claim that he or she is not
personally subject to the jurisdiction of the above-named courts, (ii) that he
or she or his or her property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through
service of notice, attachment before judgment, attachment in aid of execution of
judgment, execution of judgment or otherwise), (iii) that the proceeding in any
such court is brought in an inconvenient forum, (iv) that the venue of such
proceeding is improper or (v) that this Agreement, or the subject matter hereof,
may not be enforced in or by such court. Nothing herein shall affect the right
of any party hereto to serve process in any other manner permitted by law.

         IN WITNESS WHEREOF, Parent, Purchaser and the Stockholders have caused
this Agreement to be duly executed as of the day and year first above written.

good and marketable title to the Stockholder's Owned Shares, free and clear of
all Encumbrances, except for any Encumbrance arising under the Securities Act of

hereof, the Stockholder owns the number of shares of Company Common Stock set
forth under the Stockholder's signature at the end of this Agreement. Effective
with the execution of this Agreement, the Stockholder hereby waive any rights
which he may have with respect to any other stockholder's Owned Shares under the
Stockholders' Agreement dated November 18, 1987.

Parent or Purchaser, the consummation by Parent or Purchaser of the transactions
contemplated hereby or compliance by Parent or Purchaser with any of the
provisions hereof shall (i) conflict with or result in any breach of the
Certificate of Incorporation or By-Laws of Parent or Purchaser, or (ii) result

conditions or provisions of any note, loan agreement, bond, mortgage, indenture,
license, contract, commitment, arrangement, understanding, agreement or other

Purchaser in the Offer (the "Offer Price"), but not any additional amounts paid
or payable to holders of Company Common Stock that do not participate in the

of any Acquisition Proposal. Any action taken by the Company or any member of
the Board of Directors of the Company in his or its capacity as such to the
extent permitted and in accordance with the terms of Section 5.4(b) of the
Merger Agreement shall be deemed not to violate this Section 5(b).

         6. STOP TRANSFER AND LEGEND. The Stockholder shall not request that the
Company register the transfer (book-entry or otherwise) of any certificate or

         10. MISCELLANEOUS.

                  (a) This Agreement constitutes the entire agreement among the
parties with respect to the subject matter hereof and supersede all prior
agreements; understandings, representations and warranties, both written and
oral, between the parties with respect to the subject matter hereof, including,

                  (c) Except as provided below, all costs and expenses incurred

proceeding will be entitled to recover in such legal proceeding from the losing
party such prevailing party's costs and expenses incurred in connection with
such legal proceeding, including reasonable attorneys' fees. The provisions of

successors, personal or legal representatives, executors, administrators, heirs,

                          Attention:  Gerald E. Rudman, Esq.

                  (g) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent


                                      -7-
<PAGE>   8
of such prohibition or unenforceability without affecting the validity or
enforceability of the remaining provisions hereof. Any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable, provided the commercial objective of this
Agreement is not frustrated.

                  (h) Each of the parties hereto acknowledges and agrees that in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached, each
non-breaching party would be irreparably and immediately harmed and could not be
made whole by monetary damages. Accordingly, it is agreed that the parties
hereto (i) shall be entitled to an injunction or injunctions to prevent breaches
of this Agreement and to compel specific performance of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity, and (ii) will waive, in any proceeding for specific performance, the
defense of adequacy of a remedy at law. Each of the parties further agrees to
waive any requirement for the securing or posting of any bond or other security
in connection with any proceeding for specific performance.

                  (i) All rights, powers and remedies provided under this
Agreement or otherwise available in respect hereof at law or in equity shall be
cumulative and not alternative, and the exercise of any thereof by any party
shall not preclude the simultaneous or later exercise of any other such right,
power or remedy by such party. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

                  (j) This Agreement shall be governed and construed in
accordance with the Maine Business Corporations Act (the "MBCA"), where
applicable, and otherwise with the laws of the State of New York without giving
effect to the principles of conflicts of law thereof or of any other
jurisdiction.

                  (k) This Agreement may be executed in counterparts, each of
which shall be deemed to be an original, but all of which, taken together, shall
constitute one and the same instrument. This Agreement may be executed by
facsimile signatures and such signature shall be deemed binding for all purposes
hereof, without delivery of an original signature being thereafter required.

                  (l) Any legal action or proceeding with respect to this
Agreement or any matters arising out of or in connection with this Agreement or
otherwise, and any action for enforcement of any judgment in respect thereof
shall be brought exclusively in the courts of the State of New York or of the
United States of America for the Western District of New York or the state or
federal courts located in the State of Maine, to the


                                      -8-
<PAGE>   9
extent the proceeding involves an interpretation or enforcement of the MBCA,
and, by execution and delivery of this Agreement, each of the Tendering
Stockholder, Parent and Purchaser each hereby accept for themselves and in
respect of their respective property, generally and unconditionally, the
exclusive jurisdiction of the aforesaid courts and appellate courts thereof.
Each of the Stockholder, Parent and Purchaser irrevocably consents to service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, or by recognized international express carrier or delivery service, to
any Stockholder at the address referred to in Section 11(f).

                  (m) Each of the Stockholder, Parent and Purchaser each hereby
irrevocably waives any objection which he or she may now or hereafter have to
the laying of venue of any of the aforesaid actions or proceedings arising out
of or in connection with this Agreement or otherwise brought in the courts
referred to above and hereby further irrevocably waives and agrees, to the
extent permitted by applicable law, not to plead or claim in any such court, by
way of motion, as a defense, counterclaim or otherwise, in any action or
proceeding with respect to this Agreement, (i) any claim that he or she is not
personally subject to the jurisdiction of the above-named courts, (ii) that he
or she or his or her property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through
service of notice, attachment before judgment, attachment in aid of execution of
judgment, execution of judgment or otherwise), (iii) that the proceeding in any
such court is brought in an inconvenient forum, (iv) that the venue of such
proceeding is improper or (v) that this Agreement, or the subject matter hereof,
may not be enforced in or by such court. Nothing herein shall affect the right
of any party hereto to serve process in any other manner permitted by law.

         IN WITNESS WHEREOF, Parent, Purchaser and the Stockholders have caused
this Agreement to be duly executed as of the day and year first above written.

January 12, 1999




William Hoskins
Vice President - Sales
Penobscot Shoe Company
P.O. Box 545
Old Town, ME 04468

Dear Bill:

         Upon the recommendation of the Compensation Committee of the Board of
Directors of Penobscot Shoe Company (the "Company"), the Board has recognized
that its senior executives are apt to be subjected to unusual diversions and
apprehensions in the present corporate environment and deems it in the best
interests of the Company and its Shareholders to provide selected senior
executives with additional job security.

         The Board views your continued allegiance and dedication to your
responsibilities as most essential to the Company's success in normal operating
periods, as well as in periods of unsolicited tender offers for our shares,
other takeover bids or any transaction which would result in a change of
control. In particular, the Board believes it important, should the Company
receive proposals from third parties with respect to its future, or should the
Board move toward acquisitions or mergers on its own initiative, that you
should, without being influenced by perceived uncertainties of your position, be
able to assess and advise the Board as to whether such contemplated action will
be in the best interests of the Company and its Shareholders.

         For the purpose of this Agreement, change of control of the Company
shall be deemed to have taken place if, as a result of: a tender offer or
exchange offer for the stock of the Company; merger or consolidation of the
Company; sale or other disposition by the Company of substantially all of the
assets not in the normal course of business; issuance of stock or other
securities of the Company; adoption of any plan or proposal for liquidation or
dissolution of the Company; reclassification of securities, recapitalization,
merger; or contested election of any combination of the foregoing transactions,
any person (including an individual or group of individuals or any corporation,
partnership or other entity) controls or has the power to vote (directly or
indirectly or in combination with one or more affiliates or associates as those
terms
<PAGE>   2
are defined in Rule 12b-2 of the Securities Exchange Commission as it now
exists) more than 50% of the voting securities of the Company or succeeds the
business of the Company.

         In recognition of the premise, and of further consideration of your
continued employment with the Company, in the event that within one year after
the effective date of the change of control of the Company, your employment with
the Company terminates, either voluntarily or involuntarily, other than by
reason of death, disability, willful misconduct or retirement under the
Company's Pension Plan, the Company will promptly pay to you, upon your request
and at your option, either (i) a lump sum payment in an amount equal to your
highest annualized base salary (whenever earned) if within 12 months, reduced by
the months elapsed since the effective date of the change of control (the
Contract Period) or (ii) monthly payments prorated, equal in the aggregate to
such lump sum payment. Either payment shall be subject to applicable deductions
for federal and states taxes.

         Whichever method you choose, you shall, as a condition of payment,
covenant to retain in confidence any confidential information known to you
concerning the Company and its business so long as such information is not
publicly disclosed for the period of two years following your date of
termination.

         Annualized base salary shall mean your annual salary only, excluding
all fringe benefits, contributions to Pension Plan, and bonuses.

         During the Contract Period, the Company will maintain your present
health insurance.

         Except as may be provided in your Plan and Stock Option Plan, the
arrangements provided by this Agreement constitute the entire obligation of the
Company to you, and payment by the Company shall constitute a full settlement
and satisfaction of any claim you might otherwise assert against the Company on
account of such termination.

         This Agreement shall be binding upon and inure to the benefit of you,
your personal representative and the Company and any successor to the Company.
Neither this Agreement nor any rights arising hereunder may be assigned or
pledged by you. If you wish to accept this Agreement, please so indicate by
signing and returning this duplicate original of this letter whereupon this
letter shall constitute a binding agreement between you and the Company.

David L. Keane
Vice President - Finance and Administration
Penobscot Shoe Company
P.O. Box 545
Old Town, ME 04468

Dear David:

         Upon the recommendation of the Compensation Committee of the Board of
Directors of Penobscot Shoe Company (the "Company"), the Board has recognized
that its senior executives are apt to be subjected to unusual diversions and
apprehensions in the present corporate environment and deems it in the best
interests of the Company and its Shareholders to provide selected senior
executives with additional job security.

         The Board views your continued allegiance and dedication to your
responsibilities as most essential to the Company's success in normal operating
periods, as well as in periods of unsolicited tender offers for our shares,
other takeover bids or any transaction which would result in a change of
control. In particular, the Board believes it important, should the Company
receive proposals from third parties with respect to its future, or should the
Board move toward acquisitions or mergers on its own initiative, that you
should, without being influenced by perceived uncertainties of your position, be
able to assess and advise the Board as to whether such contemplated action will
be in the best interests of the Company and its Shareholders.

         For the purpose of this Agreement, change of control of the Company
shall be deemed to have taken place if, as a result of: a tender offer or
exchange offer for the stock of the Company; merger or consolidation of the
Company; sale or other disposition by the Company of substantially all of the
assets not in the normal course of business; issuance of stock or other
securities of the Company; adoption of any plan or proposal for liquidation or
dissolution of the Company; reclassification of securities, recapitalization,
merger; or contested election of any combination of the foregoing transactions,
any person (including an individual or group of individuals or any corporation,
partnership or other entity) controls or has the power to vote (directly or
indirectly or in combination with one or more affiliates or associates as those
terms
<PAGE>   2
are defined in Rule 12b-2 of the Securities Exchange Commission as it now
exists) more than 50% of the voting securities of the Company or succeeds the
business of the Company.

         In recognition of the premise, and of further consideration of your
continued employment with the Company, in the event that within one year after
the effective date of the change of control of the Company, your employment with
the Company terminates, either voluntarily or involuntarily, other than by
reason of death, disability, willful misconduct or retirement under the
Company's Pension Plan, the Company will promptly pay to you, upon your request
and at your option, either (i) a lump sum payment in an amount equal to your
highest annualized base salary (whenever earned) if within 12 months, reduced by
the months elapsed since the effective date of the change of control (the
Contract Period) or (ii) monthly payments prorated, equal in the aggregate to
such lump sum payment. Either payment shall be subject to applicable deductions
for federal and states taxes.

         Whichever method you choose, you shall, as a condition of payment,
covenant to retain in confidence any confidential information known to you
concerning the Company and its business so long as such information is not
publicly disclosed for the period of two years following your date of
termination.

         Annualized base salary shall mean your annual salary only, excluding
all fringe benefits, contributions to Pension Plan, and bonuses.

         During the Contract Period, the Company will maintain your present
health insurance.

         Except as may be provided in your Plan and Stock Option Plan, the
arrangements provided by this Agreement constitute the entire obligation of the
Company to you, and payment by the Company shall constitute a full settlement
and satisfaction of any claim you might otherwise assert against the Company on
account of such termination.

         This Agreement shall be binding upon and inure to the benefit of you,
your personal representative and the Company and any successor to the Company.
Neither this Agreement nor any rights arising hereunder may be assigned or
pledged by you. If you wish to accept this Agreement, please so indicate by
signing and returning this duplicate original of this letter whereupon this
letter shall constitute a binding agreement between you and the Company.

in Rule 12B-2 of the Securities Exchange Commission as it now exists) more than
50% of the voting securities of the Company or succeeds to the business of the

(i) a lump sum payment in an amount equal to your compensation within the prior
12 months, reduced by the months elapsed since the effective date of the change
of control (the Contract Period), or (ii) monthly payments prorated, equal in
the aggregate to such lump sum payment.

retain in confidence any confidential information known to you concerning the
Company and its business so long as such information is not publicly disclosed,

                            INDEMNIFICATION AGREEMENT


         This Indemnification Agreement made as of the first day of September,
1995, by and between PENOBSCOT SHOE COMPANY, a Maine corporation located at Old
Town, Maine (the "Company"); and FRANCIS J. GUTHRIE of Cape Elizabeth,
Maine (the "Director").

         WHEREAS, the Director has served as an outside director of the Company
for a number of years; and

         WHEREAS, the ability of the Company to attract and retain the services
of highly qualified directors is essential to the continued success of the
Company; and to encourage the Director to continue to serve in this capacity,
the Company seeks to assure the Director of the most complete indemnification
permitted by law for expenses or liabilities which he may incur as a Director;
and

         WHEREAS, Article XVIII-A of the By-Laws of the Company requires
indemnification of directors and officers to the fullest extent permitted by
Maine law, but this provision could be amended as a result of a change in the
composition of the Company's shareholders or directors, and presently the
Company does not maintain directors and officers liability insurance; and

         WHEREAS, Maine law provides that the indemnification granted by law or
any By-law is not exclusive of other rights to indemnification which directors
may receive; and since the Company believes that retaining the Director's
services is very important, the Company has determined it to be fair and in the
best interests of the Company and its shareholders to enter into this Agreement.

         NOW THEREFORE, in consideration of the Director's continued service as
a director of the Company and for other good and valuable consideration, the
Company and the Director agree as follows:

         1. The Company shall fully and completely indemnify the Director if, by
reason of, or arising in whole or in part out of, the fact that he is or has
been a director, employee or agent of the Company, or at the request of the
Company, express or implied, is or was serving as a director, officer, trustee,
partner, fiduciary, employee or agent of any other corporation, partnership,
joint venture, trust, pension or other employee benefit plan or other entity or
enterprise, any of the following shall occur:

                  (a) the Director is made or threatened to be made a party to
         any threatened, pending or completed action, suit or proceeding,
         whether civil, criminal, administrative or investigative, including any
         arbitration proceeding and including any action or claim by or in the
         right of the Company (provided that he is not finally adjudicated to be
         liable to the Company, unless and to the extent that the Court in which
         such action was brought determines that he is nonetheless
<PAGE>   2
         entitled to such indemnification); unless the Director is a party
         plaintiff suing on his own behalf or on behalf of one or more of the
         shareholders of the Company, except as provided in paragraph 5 below;

                  (b) he is made subject to any inquiry or investigation; or

                  (c) he is obligated to attend any proceeding as a witness in
         any matter, whether voluntarily or involuntarily.

                  Such indemnification shall cover expenses (specifically
including attorney's fees, costs of investigation and expert witness fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding to the fullest extent
permitted by law, and shall be paid as soon as practicable but, in any case, no
later than thirty (30) days after demand.

         2. Expenses incurred by the Director or on his behalf in connection
with any such action or proceeding shall be paid by the Company in advance of
the final disposition of such action or proceeding, as soon as practicable,
after furnishing the undertakings required by Subsections 4A and 4B of Section
719 of the Maine Business Corporation Act, but, in any case, no later than
thirty (30) days after demand.

         3. The indemnification provided by this Agreement shall not be
exclusive of any right to which the Director may be entitled by law or pursuant
to the Company's Articles of Incorporation, By-Laws, any policy of insurance,
any other contract or otherwise. These rights to indemnification shall be
cumulative, and no failure or delay in exercising any such right shall operate
as a waiver of it, nor shall any single or partial exercise of it preclude its
additional or further exercise or the exercise of any other right.

         4. While the Director's rights are independent of, and not affected by,
any By-Law, provision of the Articles, or any policies of insurance maintained
by the Company, indemnification payments pursuant to this Agreement shall be
reduced by amounts actually received by him with respect to the same item by
virtue of such insurance or other indemnification by the Company.

         5. In the event that the Director institutes, in good faith, any legal
action to obtain or enforce, or is required to defend the validity or
enforceability of, any right to a benefit provided by this contract, the Company
will, regardless of the outcome of such action, pay for all actual attorneys'
fees and expenses reasonably incurred by him, as soon as practicable, but, in
any case, no later than thirty (30) days after demand.

         6. In any matter covered by this Agreement, a presumption shall exist
that the Director is entitled to indemnification, and the burden of proof shall
be upon the party seeking to deny indemnification.

         7. For so long as the Director serves in any capacity described in this
Agreement, none of the provisions hereof may be terminated or amended by the
<PAGE>   3
Company without his written consent. The provisions hereof shall be binding on
any successor to the Company, whether by consolidation, merger, acquisition of
all or substantially all of the Company's assets, or otherwise. In any case,
insofar as legally permissible, neither the ceasing to act in any such capacity,
nor the termination of this Agreement, nor a subsequent change in the law, shall
affect any rights the Director may have under this Agreement with respect to
such service, while this Agreement was in effect.

         8. In all matters covered by this Agreement, the estate of the
Director, his heirs and assigns, and any of them, shall stand in his stead and
be entitled to indemnification in the same manner and to the same extent as he
would be, where they or any of them may be liable on account of his activities
contemplated by this Agreement.

         9. This Agreement shall be governed by the law of the State of Maine.
If at any time a court or other body having jurisdiction over any of the
provisions of this Agreement shall determine that any provision is unenforceable
in any respect, it shall have no effect on any other provision, and any such
unenforceable provision shall be reduced in its operation, and not terminated,
as such court or body determines may be reasonable.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first above written.

enterprise, any of the following shall occur:

          (a)      the Director is made or threatened to be made a party to any
     threatened, pending or completed action, suit or proceeding, whether civil,
     criminal, administrative or investigative, including any arbitration
     proceeding and including any action or claim by or in the right of the
     Company (provided that he is not finally adjudicated to be liable to the
     Company, unless and to the extent that the Court in which such action was
     brought determines that he is nonetheless
<PAGE>   5
         entitled to such indemnification); unless the Director is a party
         plaintiff suing on his own behalf or on behalf of one or more of the
         shareholders of the Company, except as provided in paragraph 5 below;

                  (b) he is made subject to any inquiry or investigation; or

                  (c) he is obligated to attend any proceeding as a witness in
         any matter, whether voluntarily or involuntarily.

                  Such indemnification shall cover expenses (specifically
including attorney's fees, costs of investigation and expert witness fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding to the fullest extent
permitted by law, and shall be paid as soon as practicable but, in any case, no
later than thirty (30) days after demand.

         2. Expenses incurred by the Director or on his behalf in connection
with any such action or proceeding shall be paid by the Company in advance of
the final disposition of such action or proceeding, as soon as practicable,
after furnishing the undertakings required by Subsections 4A and 4B of Section
719 of the Maine Business Corporation Act, but, in any case, no later than
thirty (30) days after demand.

         3. The indemnification provided by this Agreement shall not be
exclusive of any right to which the Director may be entitled by law or pursuant
to the Company's Articles of Incorporation, By-Laws, any policy of insurance,
any other contract or otherwise. These rights to indemnification shall be
cumulative, and no failure or delay in exercising any such right shall operate
as a waiver of it, nor shall any single or partial exercise of it preclude its
additional or further exercise or the exercise of any other right.

         4. While the Director's rights are independent of, and not affected by,
any By-Law, provision of the Articles, or any policies of insurance maintained
by the Company, indemnification payments pursuant to this Agreement shall be
reduced by amounts actually received by him with respect to the same item by
virtue of such insurance or other indemnification by the Company.

         5. In the event that the Director institutes, in good faith, any legal
action to obtain or enforce, or is required to defend the validity or
enforceability of, any right to a benefit provided by this contract, the Company
will, regardless of the outcome of such action, pay for all actual attorneys'
fees and expenses reasonably incurred by him, as soon as practicable, but, in
any case, no later than thirty (30) days after demand.

         6. In any matter covered by this Agreement, a presumption shall exist
that the Director is entitled to indemnification, and the burden of proof shall
be upon the party seeking to deny indemnification.

         7. For so long as the Director serves in any capacity described in this
Agreement, none of the provisions hereof may be terminated or amended by the
<PAGE>   6
Company without his written consent. The provisions hereof shall be binding on
any successor to the Company, whether by consolidation, merger, acquisition of
all or substantially all of the Company's assets, or otherwise. In any case,
insofar as legally permissible, neither the ceasing to act in any such capacity,
nor the termination of this Agreement, nor a subsequent change in the law, shall
affect any rights the Director may have under this Agreement with respect to
such service, while this Agreement was in effect.

         8. In all matters covered by this Agreement, the estate of the
Director, his heirs and assigns, and any of them, shall stand in his stead and
be entitled to indemnification in the same manner and to the same extent as he
would be, where they or any of them may be liable on account of his activities
contemplated by this Agreement.

         9. This Agreement shall be governed by the law of the State of Maine.
If at any time a court or other body having jurisdiction over any of the
provisions of this Agreement shall determine that any provision is unenforceable
in any respect, it shall have no effect on any other provision, and any such
unenforceable provision shall be reduced in its operation, and not terminated,
as such court or body determines may be reasonable.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first above written.

                            INDEMNIFICATION AGREEMENT


         This Indemnification Agreement made as of the first day of September,
1995, by and between PENOBSCOT SHOE COMPANY, a Maine corporation located at Old
Town, Maine (the "Company"); and JAMES L. MOODY, JR. of Brewer, Maine (the
"Director").

         WHEREAS, the Director has served as an outside director of the Company
for a number of years; and

         WHEREAS, the ability of the Company to attract and retain the services
of highly qualified directors is essential to the continued success of the
Company; and to encourage the Director to continue to serve in this capacity,
the Company seeks to assure the Director of the most complete indemnification
permitted by law for expenses or liabilities which he may incur as a Director;
and

         WHEREAS, Article XVIII-A of the By-Laws of the Company requires
indemnification of directors and officers to the fullest extent permitted by
Maine law, but this provision could be amended as a result of a change in the
composition of the Company's shareholders or directors, and presently the
Company does not maintain directors and officers liability insurance; and

         WHEREAS, Maine law provides that the indemnification granted by law or
any By-law is not exclusive of other rights to indemnification which directors
may receive; and since the Company believes that retaining the Director's
services is very important, the Company has determined it to be fair and in the
best interests of the Company and its shareholders to enter into this Agreement.

         NOW THEREFORE, in consideration of the Director's continued service as
a director of the Company and for other good and valuable consideration, the
Company and the Director agree as follows:

     1. The Company shall fully and completely indemnify the Director if, by
reason of, or arising in whole or in part out of, the fact that he is or has
been a director, employee or agent of the Company, or at the request of the
Company, express or implied, is or was serving as a director, officer, trustee,
partner, fiduciary, employee or agent of any other corporation, partnership,
joint venture, trust, pension or other employee benefit plan or other entity or
enterprise, any of the following shall occur:

                  (a) the Director is made or threatened to be made a party to
         any threatened, pending or completed action, suit or proceeding,
         whether civil, criminal, administrative or investigative, including any
         arbitration proceeding and including any action or claim by or in the
         right of the Company (provided that he is not finally adjudicated to be
         liable to the Company, unless and to the extent that the Court in which
         such action was brought determines that he is nonetheless
<PAGE>   8
         entitled to such indemnification); unless the Director is a party
         plaintiff suing on his own behalf or on behalf of one or more of the
         shareholders of the Company, except as provided in paragraph 5 below;

                  (b) he is made subject to any inquiry or investigation; or

                  (c) he is obligated to attend any proceeding as a witness in
         any matter, whether voluntarily or involuntarily.

                  Such indemnification shall cover expenses (specifically
including attorney's fees, costs of investigation and expert witness fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding to the fullest extent
permitted by law, and shall be paid as soon as practicable but, in any case, no
later than thirty (30) days after demand.

         2. Expenses incurred by the Director or on his behalf in connection
with any such action or proceeding shall be paid by the Company in advance of
the final disposition of such action or proceeding, as soon as practicable,
after furnishing the undertakings required by Subsections 4A and 4B of Section
719 of the Maine Business Corporation Act, but, in any case, no later than
thirty (30) days after demand.

         3. The indemnification provided by this Agreement shall not be
exclusive of any right to which the Director may be entitled by law or pursuant
to the Company's Articles of Incorporation, By-Laws, any policy of insurance,
any other contract or otherwise. These rights to indemnification shall be
cumulative, and no failure or delay in exercising any such right shall operate
as a waiver of it, nor shall any single or partial exercise of it preclude its
additional or further exercise or the exercise of any other right.

         4. While the Director's rights are independent of, and not affected by,
any By-Law, provision of the Articles, or any policies of insurance maintained
by the Company, indemnification payments pursuant to this Agreement shall be
reduced by amounts actually received by him with respect to the same item by
virtue of such insurance or other indemnification by the Company.

         5. In the event that the Director institutes, in good faith, any legal
action to obtain or enforce, or is required to defend the validity or
enforceability of, any right to a benefit provided by this contract, the Company
will, regardless of the outcome of such action, pay for all actual attorneys'
fees and expenses reasonably incurred by him, as soon as practicable, but, in
any case, no later than thirty (30) days after demand.

         6. In any matter covered by this Agreement, a presumption shall exist
that the Director is entitled to indemnification, and the burden of proof shall
be upon the party seeking to deny indemnification.

         7. For so long as the Director serves in any capacity described in this
Agreement, none of the provisions hereof may be terminated or amended by the
<PAGE>   9
Company without his written consent. The provisions hereof shall be binding on
any successor to the Company, whether by consolidation, merger, acquisition of
all or substantially all of the Company's assets, or otherwise. In any case,
insofar as legally permissible, neither the ceasing to act in any such capacity,
nor the termination of this Agreement, nor a subsequent change in the law, shall
affect any rights the Director may have under this Agreement with respect to
such service, while this Agreement was in effect.

         8. In all matters covered by this Agreement, the estate of the
Director, his heirs and assigns, and any of them, shall stand in his stead and
be entitled to indemnification in the same manner and to the same extent as he
would be, where they or any of them may be liable on account of his activities
contemplated by this Agreement.

         9. This Agreement shall be governed by the law of the State of Maine.
If at any time a court or other body having jurisdiction over any of the
provisions of this Agreement shall determine that any provision is unenforceable
in any respect, it shall have no effect on any other provision, and any such
unenforceable provision shall be reduced in its operation, and not terminated,
as such court or body determines may be reasonable.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first above written.

                            INDEMNIFICATION AGREEMENT


         This Indemnification Agreement made as of the first day of September,
1995, by and between PENOBSCOT SHOE COMPANY, a Maine corporation located at Old
Town, Maine (the "Company"); and GERALD E. RUDMAN of Bangor, Maine (the
"Director").

         WHEREAS, the Director has served as an outside director of the Company
for a number of years; and

         WHEREAS, the ability of the Company to attract and retain the services
of highly qualified directors is essential to the continued success of the
Company; and to encourage the Director to continue to serve in this capacity,
the Company seeks to assure the Director of the most complete indemnification
permitted by law for expenses or liabilities which he may incur as a Director;
and

         WHEREAS, Article XVIII-A of the By-Laws of the Company requires
indemnification of directors and officers to the fullest extent permitted by
Maine law, but this provision could be amended as a result of a change in the
composition of the Company's shareholders or directors, and presently the
Company does not maintain directors and officers liability insurance; and

         WHEREAS, Maine law provides that the indemnification granted by law or
any By-law is not exclusive of other rights to indemnification which directors
may receive; and since the Company believes that retaining the Director's
services is very important, the Company has determined it to be fair and in the
best interests of the Company and its shareholders to enter into this Agreement.

         NOW THEREFORE, in consideration of the Director's continued service as
a director of the Company and for other good and valuable consideration, the
Company and the Director agree as follows:

         1. The Company shall fully and completely indemnify the Director if, by
reason of, or arising in whole or in part out of, the fact that he is or has
been a director, employee or agent of the Company, or at the request of the
Company, express or implied, is or was serving as a director, officer, trustee,
partner, fiduciary, employee or agent of any other corporation, partnership,
joint venture, trust, pension or other employee benefit plan or other entity or
enterprise, any of the following shall occur:

          (a)      the Director is made or threatened to be made a party to any
     threatened, pending or completed action, suit or proceeding, whether civil,
     criminal, administrative or investigative, including any arbitration
     proceeding and including any action or claim by or in the right of the
     Company (provided that he is not finally adjudicated to be liable to the
     Company, unless and to the extent that the Court in which such action was
     brought determines that he is nonetheless
<PAGE>   14
         entitled to such indemnification); unless the Director is a party
         plaintiff suing on his own behalf or on behalf of one or more of the
         shareholders of the Company, except as provided in paragraph 5 below;

                  (b) he is made subject to any inquiry or investigation; or

                  (c) he is obligated to attend any proceeding as a witness in
         any matter, whether voluntarily or involuntarily.

                  Such indemnification shall cover expenses (specifically
including attorney's fees, costs of investigation and expert witness fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding to the fullest extent
permitted by law, and shall be paid as soon as practicable but, in any case, no
later than thirty (30) days after demand.

         2. Expenses incurred by the Director or on his behalf in connection
with any such action or proceeding shall be paid by the Company in advance of
the final disposition of such action or proceeding, as soon as practicable,
after furnishing the undertakings required by Subsections 4A and 4B of Section
719 of the Maine Business Corporation Act, but, in any case, no later than
thirty (30) days after demand.

         3. The indemnification provided by this Agreement shall not be
exclusive of any right to which the Director may be entitled by law or pursuant
to the Company's Articles of Incorporation, By-Laws, any policy of insurance,
any other contract or otherwise. These rights to indemnification shall be
cumulative, and no failure or delay in exercising any such right shall operate
as a waiver of it, nor shall any single or partial exercise of it preclude its
additional or further exercise or the exercise of any other right.

         4. While the Director's rights are independent of, and not affected by,
any By-Law, provision of the Articles, or any policies of insurance maintained
by the Company, indemnification payments pursuant to this Agreement shall be
reduced by amounts actually received by him with respect to the same item by
virtue of such insurance or other indemnification by the Company.

         5. In the event that the Director institutes, in good faith, any legal
action to obtain or enforce, or is required to defend the validity or
enforceability of, any right to a benefit provided by this contract, the Company
will, regardless of the outcome of such action, pay for all actual attorneys'
fees and expenses reasonably incurred by him, as soon as practicable, but, in
any case, no later than thirty (30) days after demand.

         6. In any matter covered by this Agreement, a presumption shall exist
that the Director is entitled to indemnification, and the burden of proof shall
be upon the party seeking to deny indemnification.

         7. For so long as the Director serves in any capacity described in this
Agreement, none of the provisions hereof may be terminated or amended by the
<PAGE>   15
Company without his written consent. The provisions hereof shall be binding on
any successor to the Company, whether by consolidation, merger, acquisition of
all or substantially all of the Company's assets, or otherwise. In any case,
insofar as legally permissible, neither the ceasing to act in any such capacity,
nor the termination of this Agreement, nor a subsequent change in the law, shall
affect any rights the Director may have under this Agreement with respect to
such service, while this Agreement was in effect.

         8. In all matters covered by this Agreement, the estate of the
Director, his heirs and assigns, and any of them, shall stand in his stead and
be entitled to indemnification in the same manner and to the same extent as he
would be, where they or any of them may be liable on account of his activities
contemplated by this Agreement.

         9. This Agreement shall be governed by the law of the State of Maine.
If at any time a court or other body having jurisdiction over any of the
provisions of this Agreement shall determine that any provision is unenforceable
in any respect, it shall have no effect on any other provision, and any such
unenforceable provision shall be reduced in its operation, and not terminated,
as such court or body determines may be reasonable.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first above written.

                             PENOBSCOT SHOE COMPANY

                             1991 STOCK OPTION PLAN



1.       PURPOSE

         The purpose of this 1991 Stock Option Plan (the "Plan") is to advance
the interests of Penobscot Shoe Company (the "Company") by enhancing the ability
of the Company (a) to attract and retain employees who are in a position to make
significant contributions to the success of the Company; (b) to reward employees
for such contributions; and (c) to encourage these employees to take into
account the long-term interests of the Company through ownership of shares of
the Company's common stock par value $1.00 ("Common Stock").

         The Plan is intended to accomplish these goals by enabling the Company
to grant awards ("Awards") to eligible employees. Awards will be in the form of
Stock Options.

2.       ADMINISTRATION

         The Plan will be administered by the Compensation Committee of the
Board of Directors of the Company (the "Committee"). The Committee will have
authority, not inconsistent with the express provisions of the Plan, (a) to
grant Awards to such eligible employees as the Committee may select
("Participants"); (b) to determine the times of grants; (c) to determine the
number of shares of Common Stock to be covered by any Award; (d) to determine
the terms and conditions of any Award, which terms and conditions may differ
among individual Awards and Participants; (e) to prescribe the form or forms of
instruments evidencing Awards and any other instruments required under the Plan
and to change such forms from time to time; (f) to adopt, amend and rescind
rules and regulations for the administration of the Plan; (g) to interpret the
Plan and to decide any questions and settle all controversies and disputes that
may arise in connection with the Plan; and (h) to waive compliance by a
Participant with any obligation to be performed by him under an Award.

         A majority of the members of the Committee will constitute a quorum,
and all determinations of the Committee shall be made by a majority of its
members. Any determination of the Committee under the Plan may be made without
notice or meeting of the Committee by a writing signed by a majority of the
Committee members. All members of the Committee shall be disinterested persons
within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934.

3.       EFFECTIVE DATE AND TERM OF PLAN

         The Plan will become effective on the date on which it is approved by
the stockholders of the Company. Grants of Awards under the Plan may be made
prior to the date (but after adoption of the Plan by the Board of Directors),
subject to approval of the Plan by stockholders.



<PAGE>   2



         No Award may be granted under the Plan after the completion of ten
years from the date on which the Plan was adopted by the Board of Directors, but
Awards previously granted may extend beyond that date.

4.       SHARES SUBJECT TO THE PLAN

         (a) Number of Shares. Subject to adjustment as provided in Section 8,
the aggregate number of shares of Common Stock that may be delivered under the
Plan is 75,000. For purposes of this limitation, shares of Common Stock which
are forfeited will not be counted.

         (b) Shares to be Delivered. Shares delivered under the Plan will be
authorized but unissued shares of Common Stock or, if the Committee so decides
in its sole discretion, previously issued Common Stock acquired by the Company
and held in treasury. No fractional shares of Common Stock will be delivered
under the Plan.

5.       ELIGIBILITY

         Employees eligible to become Participants shall be those key employees
of the Company and its subsidiaries who, in the opinion of the Committee, are in
a position to make a significant contribution to the success of the Company or
its subsidiaries. A subsidiary for purposes of the Plan is a corporation in
which the Company owns, directly or indirectly, stock possessing 50% or more of
the total combined voting power of all classes of stock. Members of the
Committee will not be eligible to become Participants.

6.       STOCK OPTIONS

         Stock Options granted under the Plan ("Options") will be non-qualified
stock options.

         Options granted under the Plan will be subject to the following terms
and conditions and will contain such additional terms and conditions, not
inconsistent with the terms of the Plan, as the Committee deems desirable:

         (a) Exercise Price. The exercise price of each Option will be
determined by the Committee but may not be less than 100% of the fair market
value per share of Common Stock at the time the Option is granted.

         (b) Duration of Options. An Option will be exercisable during such
period or periods as the Committee may specify. The latest date on which an
Option may be exercised will be the date which is ten years from the date the
option was granted or such earlier date as may be specified by the Committee at
the time the Option is granted.

         (c) Exercise of Options.

                  (1)      Options will be exercisable at such future time or
                           times, whether or not in installments, as determined
                           by the Committee at or after the grant date.


<PAGE>   3



                           The Committee may at any time accelerate the
                           exercisability of all or any portion of any Option.

                  (2)      Any exercise of an Option must be by written notice
                           to the Company, accompanied by (i) the document
                           evidencing the Option (the "Option Certificate") and
                           any other documents required by the Committee and
                           (ii) payment in accordance with Section 6(d) below
                           for the number of shares of Common Stock for which
                           the Option is exercised.

         (d) Payment for and Delivery of Common Stock. Common Stock purchased on
exercise of an Option shall be paid for as follows: (1) in cash or by certified
check, bank draft or money order payable to the order of the Company or (2) if
so permitted by the Option Certificate, (i) through the delivery of shares of
Common Stock having a fair market value on the last business day preceding the
date of exercise equal to the purchase price or (ii) by a combination of cash
and Common Stock as provided in clauses (1) and (2)(i) above or (iii) by
delivery of a promissory note of the Participant to the Company, payable on such
terms as are specified in the Option Certificate (except that the Option
Certificate may provide that the rate of interest on the note will be the lowest
rate which is sufficient, at the time the note is given, to avoid imputation of
interest under the applicable provisions of the Code), or by a combination of
cash (or cash and Common Stock) and the Participant's's promissory note;
provided, that if the Common Stock delivered upon exercise of the Option is an
original issue of authorized Common Stock, at least so much of the exercise
price as represents the par value of such Common Stock must be paid in cash if
the Committee determines that cash payment is required by law.

         (e) Nontransferability of Options. No Option may be transferred other
than by will or by the laws of descent and distribution, and during a
Participant's lifetime an Option may be exercised only by him.

         (f) Death or Disability. If a Participant's employment with the Company
and its subsidiaries terminates by reason of death or total and permanent
disability, each Option held by the Participant will become fully exercisable
and will remain exercisable after the date of such termination for a period of
one year (subject, however, to the limitations of Section 6(b) regarding the
ten-year exercise period for such Option). In the case of a deceased
Participant, such Option may be exercised within such time limits by his
executor or administrator, or by the person or persons to whom the Option is
transferred by will or the applicable laws of descent and distribution.

         (g) Other Termination of Employment. If a Participant's employment with
the Company and its subsidiaries terminates for any reason other than death or
total and permanent disability, all Options held by the Participant that are not
then exercisable shall terminate. Options that are exercisable on the date of
termination will continue to be exercisable for a period of three months (or, if
less, the remaining exercise period set by the Option Certificate) unless the
employee has confessed to, or been convicted of, any act of fraud, theft or
dishonesty arising in the course of, or in connection with, his employment with
the Company. After completion of that three-month period (or such lesser period
as provided herein) such Options shall terminate to the extent not previously
exercised, expired or terminated.


<PAGE>   4




7.       CHANGE OF CONTROL

         Notwithstanding any other provision of this Plan, in the event of a
Change of Control of the Company each Option held by each Participant will
automatically become fully exercisable.

         As used herein, a Change of Control of the Company will be deemed to
take place if (1) any individual, corporation, partnership, company or other
entity, including a "group" as defined in section 13(d)(3) of the Securities
Exchange Act of 1934, becomes the beneficial owner of shares of stock of the
Company having 25% or more of the total number of votes that may be cast for the
election of directors of the Company, or (2) during any period of two
consecutive years, individuals who at the beginning of such period constituted
the Board of Directors of the Company cease for any reason to constitute a
majority thereof; provided, however, that any director who is not in office at
the beginning of such twenty-four month period but whose election by the Board
or whose nomination for election by the Company's stockholders was to fill a
vacancy caused by death and was approved by a vote of a least two-thirds of the
directors then still in office who either were directors at the beginning of
such period or whose election or nomination for election was previously so
approved shall be deemed to have been in office at the beginning of such period
for purposes of this definition.

8.       CHANGES IN COMPANY; SUBSTITUTE AWARDS

         (a) Changes in Stock. In the event of a stock dividend, stock split or
combination of shares, recapitalization or other change in the Company's capital
stock, the number and kind of shares of stock or securities of the Company
subject to Awards then outstanding or subsequently granted under the Plan, the
maximum number of shares of stock or securities that may be delivered under the
Plan, the purchase price, and other relevant provisions will be appropriately
adjusted by the Committee, whose determination shall be binding on all persons.

         The Committee may also adjust the number of shares subject to
outstanding Awards, the exercise price of outstanding Options and the terms of
outstanding Awards, to take into consideration material changes in accounting
practices or principles, consolidations or mergers (except those described in
Section 8(b) below), acquisitions or dispositions of stock or property or any
other event if it is determined by the Committee that such adjustment is
appropriate to avoid distortion in the operation of the Plan.

         (b) Merger, Etc. Subject to Section 7, in the event of a dissolution or
liquidation of the Company or a merger or consolidation in which the Company is
not the surviving corporation or its outstanding shares are converted into
securities of another corporation or exchanged for other consideration, all
Options granted hereunder will terminate, but at least 20 days prior to the
effective date of any such dissolution or liquidation (or 20 days prior to any
earlier related sale of substantially all the assets of the Company) or of any
such merger or consolidation, the Committee shall either make all Options
outstanding hereunder immediately exercisable or arrange that the successor or
corporation, if any, grant replacement Options.

9.       GENERAL PROVISIONS

         (a) No Distribution; Compliance with Legal Requirements, Etc. The
Committee may require each person acquiring Common Stock pursuant to an Award to
represent to and agree with the Company in writing that such person is acquiring
the Common Stock without a view to distribution hereof.

         The Company will not be obligated to deliver any shares of Common Stock
pursuant to an Award (1) until, in the opinion of the Company's counsel, all
applicable federal and state laws and regulations have been complied with, and
(2) if the outstanding Common Stock is at the time listed on any stock exchange,
until the shares to be delivered have been listed or authorized to be listed on
such exchange upon official notice of issuance, and (3) until all other legal
matters in connection with the issuance and delivery of such shares have been
approved by the Company's counsel. If the sale of Common Stock has not been
registered under the Securities Act of 1933, as amended, the Company may require
such representations or agreements as counsel for the Company may consider
appropriate to avoid violation of such Act and may require that the certificates
evidencing such Common Stock bear an appropriate legend restricting transfer.

         Notwithstanding any provision of the Plan, the Company will be under no
obligation to deliver shares of Common Stock to an estate of a deceased
Participant, or to the person or persons to whom the Award has been transferred
by the Participant's will or the applicable laws of descent and distribution,
until the Company is satisfied as to the authority of such person or persons.

         (b) Tax Withholding, Etc. Each Participant will, no later than the date
as of which any Common Stock received hereunder first becomes includable in
gross income for federal income tax purposes, pay to the Company, or make
arrangements satisfactory to the Committee regarding payment of, all federal,
state and local taxes required by law to be withheld with respect to such
income. The Company and its subsidiaries will, to the extent permitted by law,
have the right to deduct any such taxes from any payment of any kind otherwise
due to the Participant.

         The Committee may provide, in respect of any transfer of Common Stock
under an Award, that if and to the extent withholding of any federal, state or
local tax is required, the Participant may elect in such manner as the Committee
prescribes, to have the Company hold back from the transfer Common Stock having
a value calculated to satisfy withholding obligation.

         Notwithstanding the foregoing, in the case of a Participant subject to
the restrictions of Section 16(b) of the Securities Exchange Act of 1934 no such
election shall be effective unless made in compliance with any applicable
requirements of Rule 16b-3(e) or any successor rule under such Act.

         (c) Continuance of Employment. For purposes of the Plan, employment of
a Participant will not be considered terminated (1) in the case of sick leave or
other bona fide leave of absence approved for purposes of the Plan by the
Committee, so long as the Participant's right


<PAGE>   6


to reemployment is guaranteed either by statute or by contract, or (2) in the
case of a transfer to the employment of a corporation (or a parent or subsidiary
corporation of such corporation) issuing or assuming an option in a transaction
to which section 425(a) of the Code would apply.

         (d) Fair Market Value. For purposes of the Plan, in general, "fair
market value" of a share of Common Stock on any date means the closing price on
such date as reflected in the American Exchange Composite Index. If, however,
the Committee determines that a different meaning is in any circumstance
necessary in order to comply with applicable law, such different meaning will
apply in that circumstance.

         (e) Employment Rights. Neither the adoption of the Plan nor the grant
of Awards will confer upon any employee any right to continued employment with
the Company or any subsidiary or affect in any way the right of the Company or
subsidiary to terminate the employment of an employee at any time. Except as
specifically provided by the Committee in any particular case, the loss of
existing or potential profit in Awards granted under this Plan shall not
constitute an element of damages in the event termination is in violation of an
obligation of the Company to the employee by contract or otherwise.

10.      EFFECT, DISCONTINUANCE, CANCELLATION, AMENDMENT AND
         TERMINATION

         Neither adoption of the Plan nor the grant of Awards to a Participant
shall affect the Company's right to grant to such Participant awards that are
not subject to the Plan, to issue to such Participant Common Stock as a bonus or
otherwise, or to adopt other plans or arrangements under which Common Stock may
be issued to employees.

         The Committee may at any time discontinue granting Awards under the
Plan. With the consent of the Participant, the Committee may at any time cancel
an existing Award in whole or in part and grant the Participant another Award
for such number of shares of Common Stock as in the Committee specifies. The
Committee may at any time or times amend the Plan or any outstanding Award for
the purpose of satisfying the requirements of any changes in applicable laws or
regulations or for any other purpose which may at the time be permitted by law,
provided that (except to the extent expressly required or permitted herein
above) no such amendment shall, without the approval of the stockholders of the
Company, (a) increase the maximum number of shares available for delivery under
the Plan, (b) change the group of employees eligible to receive Awards under the
Plan, (c) reduce the price at which options may be granted, (d) extend the time
within which Awards may be granted, or (e) amend the provision of this Section
10, and no such amendment shall adversely affect the rights of any Participant
(without his consent) under any Award previously granted.

As adopted by the Board of Directors: December 20, 1990

As approved by the Stockholders:

                              [ADVEST, INC. LOGO]

October 6, 1999

Board of Directors
Penobscot Shoe Company
450 North Main Street
Old Town, Maine 04468

Members of the Board:

     Penobscot Shoe Company ("Penobscot" or the "Company") and Riedman
Corporation ("Riedman") are expected to enter into an Agreement and Plan of
Merger (the "Agreement"), whereby a newly created indirect wholly-owned
subsidiary of Riedman ("Merger Subsidiary") will offer to purchase all of the
issued and outstanding shares of Penobscot common stock for $11.75 per share
(the "Tender Offer"). Subsequent to the completion of the Tender Offer, Merger
Subsidiary will be merged with and into the Company (the "Merger"), and each
outstanding share of Penobscot common stock that was not acquired in the Tender
Offer will be converted into the right to receive $11.75 in cash. The Merger and
the Tender Offer together comprise the "Transaction". At the completion of the
Transaction, Penobscot will be an indirect wholly-owned subsidiary of Riedman.

     You have asked us whether, in our opinion, the cash consideration to be
received by Penobscot shareholders is fair, from a financial point of view, to
such shareholders of the outstanding shares of common stock of the Company.

     In arriving at our opinion set forth below, we have, among other things:

        (i) Reviewed the Agreement and Plan of Merger dated October 6, 1999 and
            the Tender Agreements dated October 6, 1999;

        (ii) Reviewed the drafts of Schedule 14D-9 and Schedule 14D-1 to be
             submitted to the Securities and Exchange Commission;

        (iii) Reviewed the publicly available consolidated financial statements
              of Penobscot for recent years and interim periods to date as well
              as other filings with the Securities and Exchange Commission for
              such periods;

        (iv) Reviewed the reported prices of common stock, trading activity, as
             well as publicly available financial and operating data for
             companies deemed similar to Penobscot;

          (v) Reviewed the pricing and financial terms of recent corporate
              transactions involving acquired companies deemed similar to
              Penobscot;

         (vi) Reviewed internal financial and operating information, including
              certain projections prepared by the senior management of
              Penobscot;

         (vii) Discussed the business, financial condition, and prospects of
               Penobscot with certain members of senior management; and

        (viii) Performed such other financial studies and analyses and
               investigations as we deemed necessary.

     In addition to the foregoing, we have, among other things, performed the
following analyses and investigations: (i) compared the proposed purchase price
per share to the historical trading range of Penobscot's common stock; (ii)
compared the proposed purchase price and its implied ratios ("multiples") to
sales, earnings, book value and cash flow to the same multiples calculated from
current public market valuations of publicly traded companies deemed similar to
the Company; (iii) compared the proposed purchase price and its implied
multiples of sales and cash flow to the same multiples as calculated from
valuations established in recent transactions of companies deemed similar to the
Company; (iv) analyzed and compared the proposed purchase price to the value of
estimated future free cash flows discounted to their current value; and (v)
analyzed Penobscot's historical trading activity, including volume and price
relationships. In addition, we performed such other investigations and took into
account such other matters and information as we deemed necessary.

     Advest has provided certain investment banking services to Penobscot in the
past and has received fees for rendering these services, including a fee for
advising the Company on this Transaction. As part of our engagement, the Company
has agreed to pay Advest a fee for delivery of this opinion letter.

     In preparing this opinion, we have relied on the accuracy and completeness
of all information supplied or otherwise made available to us by the Company,
and we have not independently verified such information, nor have we undertaken
an independent appraisal of the assets or liabilities of the Company. This
opinion is necessarily based upon circumstances and conditions as they exist and
can be evaluated by us as of the date of this letter. Our opinion is directed to
the Board of Directors of Penobscot and does not constitute a recommendation of
any kind to any shareholder of Penobscot as to whether such shareholder should
tender his or her stock in the Tender Offer or how such shareholder should vote
at the shareholders' meeting to be held in connection with the Merger. We have
assumed for purposes of this opinion that there have been no material changes in
the financial condition of the Company from the conditions disclosed in the
Company's financial reports.

     Advest hereby consents to a description and inclusion of this opinion in
any public filings issued with regard to this transaction and to references to
Advest in such documents. Except as otherwise provided above, this opinion is
solely for the use and benefit of the Company and shall not be disclosed
publicly or made available to third parties without the prior written approval
of Advest.

     In reliance upon and subject to the foregoing, it is our opinion that, as
of the date hereof, the cash consideration to be received by the Company's
shareholders in the Transaction is fair, from a financial point of view, to the
Company's shareholders.

                                                                October 12, 1999

To Our Stockholders:

     We are pleased to inform you that on October 6, 1999, Penobscot Shoe
Company (the "Company") entered into an Agreement and Plan of Merger (the
"Merger Agreement") with Riedman Corporation ("Parent") and PSC Acquisition
Corp. ("Purchaser"), an indirect wholly owned subsidiary of Parent. Pursuant to
the Merger Agreement, Purchaser has commenced a cash tender offer (the "Offer")
to acquire all of the issued and outstanding shares of the Company's common
stock, $1.00 par value per share (the "Shares"), for $11.75 per share, net to
the seller in cash. Under the terms of the Merger Agreement, as soon as
practicable after the consummation of the Offer and subject to the terms and
conditions set forth in the Merger Agreement, the Company will merge with and
into the Purchaser (the "Merger"), and each remaining share which is then issued
and outstanding will be converted into the right to receive $11.75 net to the
seller in cash (or any higher price that may be paid in the Offer), without
interest.

     THE BOARD OF DIRECTORS OF THE COMPANY UNANIMOUSLY (A) DETERMINED THAT THE
MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER
AND THE MERGER, ARE FAIR TO AND IN THE BEST INTERESTS OF THE COMPANY'S
STOCKHOLDERS, (B) ADOPTED AND APPROVED THE MERGER AGREEMENT AND AUTHORIZED THE
EXECUTION THEREOF BY THE COMPANY AND (C) RECOMMENDS THAT THE STOCKHOLDERS OF THE
COMPANY ACCEPT THE OFFER.

     To arrive at its recommendation, the Board of Directors carefully evaluated
a number of factors as described in the attached Offer to Purchase of the
Purchaser, dated October 12, 1999, and the Schedule 14D-9 that is being filed
today with the Securities and Exchange Commission. These factors include, among
other things, the opinion of Advest, Inc., the Company's financial advisor, that
the $11.75 per Share that stockholders of the Company will receive pursuant to
the Merger Agreement is fair from a financial point of view to these
stockholders. The full text of the written opinion of Advest, Inc., which sets
forth assumptions made, matters considered and limitations on the review
undertaken in connection with the opinion, is attached as an Exhibit to the
attached Schedule 14D-9 that is being filed today with the Securities and
Exchange Commission. Stockholders are urged to read this opinion in its
entirety.

     In addition to the attached Schedule 14D-9 relating to the Offer and the
Offer to Purchase are related tender offer materials, including a Letter of
Transmittal to be used for tendering your Shares. These documents set forth the
terms and conditions of the Offer and Merger and provide instructions as to how
to tender your Shares. We urge you to read the enclosed material carefully.

                                          Sincerely,

                                          /S/ Irving Kagan
                                          Irving Kagan
                                          Chairman of the Board of Directors
