THE 1985 PLAN The 1985 Long-Term Incentive Plan became effective January 1, 1985 and was approved at the 1985 annual meeting of stockholders. The Board of Directors on February 6, 1987 amended the Plan in a number of respects by adopting the 1985 Long-Term Incentive Plan as Amended and Restated, which was approved at the 1987 annual meeting of stockholders. At the 1990 annual meeting the Plan was amended by increasing from 800,000 to 1,000,000 the maximum number of shares issuable upon the exercise of options or stock appreciation rights. The Plan was further amended July 30, 1992 to bring the Plan in compliance with the requirements of Rule 16b-3 (as amended May 1, 1991) under the Securities Exchange Act of 1934, as amended, and remove certain restrictions and procedures which are no longer necessary in order to comply with that Rule. The July 1992 amendments had no effect on stock options granted prior to those amendments, except to the extent that the stock option agreement may be amended in writing in accordance with the Plan. At the 1994 annual meeting the stockholders approved amendments to the Plan which increased from 1,000,000 to 1,500,000 the maximum number of shares of common stock issuable upon the exercise of options or stock appreciation rights and extended from January 1, 1995 to January 1, 2005 the termination date of the Plan. Finally, on May 25, 2005 the Plan was amended by deleting the authority to award stock appreciation rights ("SARs") to optionees. No SARs or Incentive Stock Options were awarded under the Plan. The 1985 Long-Term Incentive Plan as Amended and Restated is hereinafter referred to as the "1985 Plan". The 1985 Plan expired January 1, 2005; however, stock options granted prior to the expiration date remain in effect in accordance with their terms. The purpose of the 1985 Plan was to provide financial incentives for selected key personnel and directors of the Company and its subsidiaries, thereby promoting the long-term growth and financial success of the Company by (i) attracting and retaining personnel and directors of outstanding ability, (ii) strengthening the Company's capability to develop, maintain and direct a competent management team, (iii) motivating key personnel to achieve long-range performance goals and objectives and (iv) providing incentive compensation opportunities competitive with those of other corporations. The 1985 Plan was neither qualified under Section 401 of the Internal Revenue Code nor subject to any provisions of the Employee Retirement Income Security Act of 1974. The following summary of the 1985 Plan is qualified in its entirety by reference to the 1985 Plan, copies of which have been filed with the Commission and furnished to the recipients of stock options. Eligibility The 1985 Plan authorized the granting of stock options to officers and employees of the Company and its subsidiaries who occupied responsible executive, professional or administrative positions and who had the capacity to contribute to the success of the Company. Options could also be granted to directors of the Company and its subsidiaries who were not employees of the Company or a subsidiary. Employees were required to be in grade level 15 or above or otherwise selected for participation. As of June 7, 2006 there were 16 participants in the 1985 Plan. Administration Awards to participants are administered by a committee composed of two or more directors of the Company, each of whom is a "non-employee director" within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, as amended, (the "Committee"). Members of the Committee are appointed by and serve at the pleasure of the Board of Directors. The Committee was authorized, in its discretion but within the parameters set forth in the 1985 Plan, to determine those officers, employees and directors who would receive awards, the number of shares to be optioned and the time or times when awards would be made, and to grant such awards. The Committee is authorized to interpret the terms and provisions of the 1985 Plan. The Committee's interpretations of the awards are final and conclusive as to all interested parties. The Committee has general authority to interpret the Plan and establish rules and regulations for its administration. As of the date of this Prospectus, the members of the Committee were John W. Puth, J.W. Puth Associates, 5215 Old Orchard Road, Skokie, IL 60077, William H. Rackoff, ASKO, Inc. 501 West 7th Avenue, Homestead, Pa 15120, Henry J. Massman IV, Massman Construction Co., 8901 State Line Road, Kansas City, MO 64114 and G. Thomas McKane, c/o L.B. Foster Company, 415 Holiday Drive, Pittsburgh, PA 15220. Stock Option Grants Up to 1,500,000 shares of Common Stock of the Company may be issued or delivered by the Company under the 1985 Plan, which may include newly-issued or treasury shares. The number and kind of shares that may be issued, the number of shares subject to outstanding options, the exercise (purchase) price per share and other relevant provisions are subject to appropriate adjustment for stock splits, stock dividends, reverse splits, recapitalizations, a merger in which the Company is the surviving corporation or other similar capital changes. Such adjustment shall be as determined by the Board of Directors, whose determination shall be binding on all persons. Nonqualified stock options. The stock options granted under the 1985 Plan are "nonqualified" in that they do not qualify as "incentive stock options" within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). Terms and Provisions of Stock Options The Committee was authorized to determine the terms and provisions of stock options granted under the 1985 Plan, provided that (a) the exercise price could not be less than the fair market value (as defined) of the stock on the date of grant, as determined by the Committee, and (b) the option must expire no later than ten years from the date of grant. The terms and provisions of option grants were not required to be uniform. Unless otherwise provided in the stock option agreement, (a) the options are exercisable in cumulative annual installments in the amount of 25% of the shares optioned, commencing on the first anniversary of the grant, (b) in the case of death, the option may be exercised by the optionee's legal representative within 12 months after the date of death, but only to the extent the option was exercisable at the time of death, (c) in the case of retirement with the consent of the Company or Permanent Disability, the option may be exercised within three years after termination of service for such reason, but only to the extent that the option was exercisable at the time of such termination of service and (d) if the optionee's service with the Company or a subsidiary of the Company terminates for any reason other than death, retirement with the consent of the Company or Permanent Disability, all options held by the optionee will immediately terminate and may not thereafter be exercised; provided, however, that if the optionee's service terminates more than four years after the grant of the option and if the optionee's service is not terminated for "cause", the optionee may exercise the option within 30 days after such termination of service. Notwithstanding the foregoing, in no event may any option be exercised after the expiration of ten years from the date on which it was granted. "Cause" includes willful or gross neglect of duties or willful misconduct in the performance of duties, so as to cause material harm to the Company or any subsidiary as determined by the Board of Directors; fraud, misappropriation or embezzlement in the performance of duties; or conviction of a felony which, as determined in good faith by the Board of Directors, constitutes a crime involving moral turpitude and results in material harm to the Company or a subsidiary. The Committee is authorized to determine whether an optionee has retired from service or has suffered Permanent Disability, and its determination shall be binding on all concerned. In the sole discretion of the Committee, a transfer of service to an affiliate of the Company other than a subsidiary of the Company may be deemed retirement from service with the consent of the Company. Except as otherwise provided in the stock option agreement, an optionee's service will be treated as continuing while the optionee is on military leave, sick leave or other bona fide leave of absence if the period of such leave does not exceed 90 days or, if longer, the optionee's right to reestablish his or her service is guaranteed by statute or by contract; absent such statute or contract, the optionee's service will be deemed to have terminated on the 91st day of such leave. The Committee is also authorized, in its discretion, to accelerate the date on which an option may be exercised, if it determines that to do so will be in the best interests of the Company and the optionee. Stock option agreement. Each stock option is evidenced by a stock option agreement in such form and containing such provisions, not inconsistent with the provisions of the 1985 Plan, as the Committee approved. The terms and provisions of such agreements were not required to be uniform. Each optionee should therefore refer to his or her own stock option agreement for the terms and provisions of the option. Exercise of Stock Options and Disposition of Shares Manner of exercise. Stock options may be exercised by giving written notice of exercise to the Company specifying the number of shares to be purchased. The notice of exercise must be accompanied by (a) payment in full of the exercise price in cash or by certified or cashier's check or (b) a copy of irrevocable instructions to a broker to promptly deliver to the Company the amount of sale or loan proceeds sufficient to cover the exercise price. Conditions to delivery of shares. The Company will not be obligated to deliver any shares upon the exercise of an option unless and until, in the opinion of the Company's counsel, all applicable federal, state and other laws and regulations have been complied with. If the outstanding stock at the time of exercise is listed on any stock exchange, no delivery will be made unless and until the shares to be delivered have been listed or authorized for listing upon official notice of issuance on such exchange. Nor will delivery be made until all other legal matters in connection with the issuance and delivery of shares have been approved by the Company's counsel. In this regard, and without limiting the generality of the foregoing, the Company may require from the optionee or the optionee's legal representative such investment representation or such agreement, if any, as legal counsel for the Company may consider necessary in order to comply with the Securities Act of 1933, as amended, the securities laws of any state and the regulations thereunder, certificates evidencing the shares may be required to bear a restrictive legend, a stop transfer order may be placed with the transfer agent, and there may be restrictions as to the number of shares that can be resold during a given period of time and the manner of sale. Optionees or their legal representatives must take any action reasonably requested by the Company in order to effect compliance with all applicable securities laws and regulations and any listing requirements. Notice of disposition of shares. Each optionee must notify the Company when any disposition of optioned shares, whether by sale, gift or otherwise, is made by the optionee. Miscellaneous Provisions Nontransferability. No stock option awarded under the 1985 Plan is transferable by the optionee other than by will or the laws of descent and distribution. Any transfer contrary to this restriction will nullify the award. Options are exercisable during the optionee's lifetime only by the optionee or the optionee's legal representative. Shareholder rights. An optionee has no rights as a shareholder with respect to any stock covered by his or her option until the issuance to the optionee of a stock certificate representing such stock. No right to employment. Neither the establishment of the 1985 Plan nor any action taken by the Company, the Board, or the Committee under the 1985 Plan, nor any provision of the 1985 Plan, shall be construed as giving to any person the right to be retained in the service of the Company or any subsidiary. Consolidation or merger. In the event of a consolidation or a merger in which the Company is not the surviving corporation, or any other merger in which the shareholders of the Company exchange their shares of stock in the Company for stock of another corporation, or in the event of complete liquidation of the Company, or in the case of a tender offer accepted by the Board of Directors, all outstanding options will thereupon terminate, provided that the Board may, prior to the effective date of any such consolidation or merger, either (a) make all outstanding options immediately exercisable or (b) arrange to have the surviving corporation grant to the optionees replacement options on terms which the Board determines to be fair and reasonable. Amendments. The Board of Directors may at any time amend the 1985 Plan or amend any outstanding option 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 no such amendment shall result in Rule 16b-3 under the Securities Exchange Act of 1934, as amended, becoming inapplicable to any options or without the approval of the shareholders of the Company (a) increase the maximum number of shares of common stock available under the 1985 Plan (subject to adjustment as explained above), (b) reduce the exercise price of options below the prices provided for in the 1985 Plan, (c) extend the time within which options may be granted, or (d) extend the period of an outstanding option beyond ten years from the date of grant. No amendment shall adversely affect the rights of any optionee under any award theretofore granted except upon the optionee's written consent to such amendment. Amendments requiring the approval of shareholders may be effected by the Board subject to such approval. THE 1998 PLAN On October 23, 1998, the Board of Directors adopted the 1998 Long-Term Incentive Plan which provided for the issuance of options to acquire up to 25,000 shares of the Company's common stock. Options to acquire 25,000 shares of common stock were subsequently awarded to outside directors of the Company. On February 24, 1999, the Board of Directors adopted, subject to shareholder approval, an amended and restated 1998 Long-Term Incentive Plan which, among other things, increased the number of shares of Common Stock which may be issued under that Plan from 25,000 to 450,000. On February 2, 2001 the Board of Directors adopted, subject to shareholder approval, a further amended and restated 1998 Long-Term Incentive Plan which increased the number of shares which may be issued under the Plan from 450,000 to 900,000. That Plan was approved at the annual meeting of shareholders on May 9, 2001. On May 25, 2005, the Plan was amended by deleting the authority to award SARs or Incentive Stock Options to participants and in certain other respects (as so amended, the "1998 Plan"). No SARs or Incentive Stock Options have been awarded under the 1998 Plan. The Plan will expire on October 22, 2008, unless terminated on an earlier date by the Board. As of June 7, 2006 there were 31 participants in the 1998 Plan. The purpose of the 1998 Plan is to provide financial incentives for selected key personnel and directors and to enable the Company to offer competitive compensation to them. The 1998 Plan is neither qualified under Section 401 of the Code nor subject to any provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). The following summary of the 1998 Plan is qualified in its entirety by reference to the 1998 Plan, copies of which have been filed with the Commission and furnished to the recipients of stock options. Administration The 1998 Plan is administered by a Committee consisting of either (a) at least two "non-employee" directors (within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934) or (b) the full Board of Directors. The Committee currently consists of Henry J. Massman IV, G. Thomas McKane, John W. Puth and William H. Rackoff. Within the parameters set forth in the 1998 Plan, the Committee has the authority to determine those key employees or directors who shall receive a discretionary award and the terms and conditions of each such award. The Committee may also prescribe regulations for the operation of the 1998 Plan and interpret the 1998 Plan and option agreements issued under the 1998 Plan. In addition to discretionary awards made by the Committee, non-employee directors were automatically awarded options to acquire up to 5,000 shares of Common Stock after each annual shareholders meeting. These automatic awards, which have been discontinued, are described below under "Automatic Stock Options." General Up to 900,000 shares of Common Stock of the Company may be issued under the 1998 Plan, which may include newly issued or treasury shares. An option's exercise price must be at least the fair market value of the shares on the day the option is granted. Each option must be evidenced by a stock option agreement in a form prescribed by the Committee. Options granted under the 1998 Plan are not transferable other than by will or the laws of descent and distribution. Options may be exercised by giving written notice of exercise to the Company specifying the number of shares to be purchased. The notice of exercise must be accompanied by (a) payment in full of the exercise price in cash, certified check or other medium acceptable to the Company in its sole discretion or (b) a copy of irrevocable instructions to a broker to promptly deliver to the Company the amount of sale or loan proceeds sufficient to cover the exercise price. The number of shares that may be issued under the 1998 Plan and the number and price of shares subject to outstanding options are subject to appropriate adjustment for stock splits, stock dividends, reverse splits, reclassifications and other similar events. Each optionee must notify the Company when any disposition of optioned shares, whether by sale, gift or otherwise, is made by the optionee. Awards under the 1998 Plan consist of "non-qualified" stock options in that they do not qualify as "incentive stock options" within the meaning of Section 422 of the Code. Automatic Stock Options Immediately after each annual meeting of shareholders, each non-employee director who was elected at the meeting or whose term in office continued after the meeting was automatically granted an option to purchase up to 5,000 shares of Common Stock, subject to adjustment for any future stock splits, stock dividends, reverse splits, reclassifications or other similar events (the "Automatic Options"). The Automatic Options have an exercise price per share equal to the fair market value of the Common Stock on the date of the meeting, have a term of ten years and were immediately exercisable. When a director has served less than five years, the director may exercise his or her Automatic Options only within one year after termination of service, unless the director's service is terminated due to death, disability or retirement with the consent of the Company, in which case the options may be exercised during their full ten year term. A director who has served five years or longer may exercise his or her Automatic Options during their full ten year term. Notwithstanding the foregoing, if a director is removed for cause, all of his or her Automatic Options shall immediately terminate. On May 24, 2006, the Company's shareholders approved the 2006 Omnibus Incentive Plan and the 1998 Plan was amended so that automatic stock options awards are no longer made. Discretionary Stock Options In addition to the Automatic Options, stock options may be granted to key personnel and directors, including both employee directors and non-employee directors, in the discretion of the Committee ("Discretionary Options"). Discretionary Options granted to directors are hereinafter referred to as "Director Options." Discretionary Options are subject to the following provisions of the 1998 Plan, and the terms and provisions of such options need not be uniform: Eligibility. Discretionary Options may be granted by the Committee to directors or to key employees who occupy a responsible executive, sales, professional or administrative position and, in the Committee's view, have the capacity to contribute to the success of the Company. In addition to the Company's non-employee directors, the Company has approximately 90 employees, out of approximately 645 total employees, whose grade level makes them likely candidates for option awards. Exercise Price. The exercise price of Discretionary Options is determined by the Committee, but shall be not less than the fair market value of the Common Stock on the date of grant. Term. The term of Discretionary Options is determined by the Committee, but shall not exceed ten years from the date of grant. Director Options have the same early-termination provisions as Automatic Options. The early-termination provisions of the 1998 Plan as to all other Discretionary Options are the same as those of the 1985 Plan. See "THE 1985 PLAN - Terms and Provisions of Stock Options." Vesting. Options granted to outside directors are immediately exercisable. Except as otherwise provided in the option agreement, all other Discretionary Options may be exercised in cumulative annual installments, each for one-fourth of the total optioned shares, commencing one year from the date of grant. Amendments and Termination The Board of Directors may at any time amend the 1998 Plan or amend any outstanding option for purposes of satisfying the requirements of any changes in applicable laws or regulations or, in the case of Discretionary Options, for any other purpose which may at the time be permitted by law; provided, however, that no such amendment is permissible if it would result in Rule 16b-3 becoming inapplicable to any options, nor may any such amendment adversely affect the rights of any participant in the 1998 Plan under any option theretofore granted to such participant except upon his or her written consent to such amendment. The Board may terminate the 1998 Plan at any time. However, awards made prior to the expiration or termination of the 1998 Plan will remain in effect in accordance with their terms. In the event of a consolidation or merger in which the Company is not the surviving corporation, or any other merger in which the shareholders of the Company exchange their shares of stock in the Company for stock of another corporation, or in the event of complete liquidation of the Company, or in the case of a tender offer accepted by the Board, all outstanding stock options shall thereupon terminate, provided that the Board may, prior to the effective date of any such consolidation or merger, either (a) make all outstanding options immediately exercisable or (b) arrange to have the surviving corporation grant to the participants replacement options on terms which the Board shall determine to be fair and reasonable. THE 2006 PLAN On March 3, 2006 the Board of Directors approved the 2006 Omnibus Incentive Plan, subject to shareholder approval. The 2006 Plan provides for the issuance of up to 500,000 shares of the Company's Common Stock, which may include newly-issued or treasury shares, through the exercise of stock options or the award of restricted shares of Common Stock. The purposes of the Plan include motivating employees and directors to achieve long-term performance goals and to provide such employees and directors with competitive compensation. The 2006 Plan is neither qualified under Section 401 of the Code nor subject to any provisions of ERISA. As of June 1, 2006, there were 5 participants in the 2006 Plan. Administration The Plan is administered by a committee (the "Committee") consisting of either (a) at least two "non-employee" directors (within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934) or (b) the full Board of Directors. The Compensation Committee of the Board, which currently consists of Messrs. Massman, McKane, Puth and Rackoff, currently administers the Plan. Within the parameters set forth in the Plan, the Committee has the authority to determine those key employees and directors who shall receive a discretionary award and the terms and conditions of each such award. The Committee may also prescribe regulations for the operation of the Plan and interpret the Plan and option or restricted stock agreements issued under the Plan. These automatic awards are described below. Stock options and stock awards may be granted, in the Committee's discretion, to key personnel and directors, including both employee and non-employee directors in the discretion of the Committee. Stock options and stock awards granted to non-employee directors are hereinafter respectively referred to as "Director Options" and "Director Awards." The provisions of stock options and stock awards need not be uniform. Stock Options The exercise price of stock options is determined by the Committee, but shall be not less than the last reported sale price of the Common Stock on the NASDAQ National Market on the date of grant. The exercise price is payable in cash or other medium acceptable to the Company. The term of options is determined by the Committee, but shall not exceed ten years from the date of grant. Except as otherwise provided in the option agreement, options, other than Director Options, will terminate 30 days after termination of the optionee's employment with the Company for any reason other than death, permanent disability or retirement with the consent of the Company. Director Options are immediately exercisable for a period of ten years from the date of the award. Except as otherwise provided in the option agreement, other discretionary options may be exercised in cumulative annual installments, each for one-fourth of the total optioned shares, commencing one year from the date of grant. Stock Awards Commencing with the May 24, 2006 annual meeting, at each annual meeting of shareholders each non-employee director automatically will be granted a Director Award of 3,500 shares of fully vested Common Stock. Awards may also be granted to key personnel and directors in the discretion of the Committee. Such stock awards will become vested and/or saleable pursuant to the terms of the applicable stock award agreement approved by the Committee. Amendments and Termination The Board may at any time amend the Plan or amend any outstanding award agreement for the purpose of satisfying any legal requirement or for any other legal permissible purpose; provided that an amendment shall not be deemed permissible if it would result in Rule 16b-3 under the Securities Exchange Act of 1934, as amended, being inapplicable to any award. The Board may terminate the Plan at any time, but no such termination shall adversely affect the rights of any participant under any award previously granted in which the participant has a vested interest, except upon his or her written consent. In the event of a stock dividend, recapitalization or merger in which the Company is the surviving corporation or other similar capital change, the number and shares of stock then outstanding or to be awarded thereunder, the maximum number of shares of stock or securities which may be issued on the exercise of options granted under the Plan, the exercise price and other relevant provisions shall be appropriately adjusted by the Board. In the event of a consolidation or a merger in which the Company is not the surviving corporation, or any other merger in which the shareholders of the Company exchange their shares of stock in the Company for stock of another corporation, or in the event of a complete liquidation of the Company, or in the case of a tender offer accepted by the Board of Directors, all outstanding options shall thereupon terminate, provided that the Board may, prior to the effective date of any such consolidation or merger, either (i) make all outstanding options immediately exercisable or (ii) arrange to have the surviving corporation grant to the participants replacement options on terms which the Board shall determine to be fair and reasonable. CERTAIN FEDERAL INCOME TAX CONSEQUENCES Under the Internal Revenue Code of 1986 as in effect on the date of this Prospectus, there is no taxable income to an optionee when an option is granted to him or her under the 1985, the 1998 or the 2006 Plan; however, upon exercise of the option, the excess of the fair market value of the underlying shares on the date of exercise over the option exercise price for such shares will be taxable to the optionee as ordinary income. The Company will be entitled to a corresponding tax deduction for any amounts which are taxable to an optionee as ordinary income. If at any time an optionee is treated as receiving ordinary income and at that time he or she is employed by the Company or any of its affiliates, the Company may be required to withhold federal income taxes and also may be required to withhold contributions under the Federal Insurance Contributions Act (FICA) from either the source of such ordinary income or other income payable to the optionee. In addition, whenever stock is to be delivered to an optionee, the Company may (a) require the optionee to remit an amount in cash sufficient to satisfy all federal, state and local tax withholding requirements related thereto, (b) withhold such required withholding from compensation otherwise due to the optionee or (c) any combination of (a) and (b). A grantee will not recognize any income upon the grant of restricted stock if that stock is subject to a substantial risk of forfeiture on the date of grant, unless the holder elects under Section 83(b) of the Code, within 30 days of the grant, to recognize ordinary income in an amount equal to the fair market value of the restricted stock at the time of receipt, less any amount paid for the shares. If the Section 83(b) election is made, the holder will not be allowed a deduction in the event that the shares are substantially forfeited. If the election is not made, the holder will generally recognize ordinary income on the date that the restricted stock is no longer subject to a substantial risk of forfeiture, in an amount equal to the fair market value of those shares on that date, less any amount paid for the shares. At the time the holder recognizes ordinary income, the Company generally will be entitled to a deduction in the same amount. Generally, upon a sale or other disposition of restricted stock with respect to which the holder has recognized ordinary income (i.e., a Section 83(b) election was previously made) or the restrictions were previously removed, the holder will recognize capital gain or loss in an amount equal to the difference between the amount on that sale or other disposition and the holder's basis in those shares. Because of the complexity of the federal income tax laws and the possibility of changes therein, and because the tax consequences to a particular participant will at least in part depend upon his or her personal financial situation, participants are urged to consult their personal tax advisors before exercising their options or reselling shares acquired under the 1985 Plan, the 1998 Plan or the 2006 Plan. Participants should also consult their personal tax advisors as to the state, local and federal estate tax consequences of such transactions.

Item 9. Undertakings. The Company undertakes to deliver or cause to be delivered with the prospectus to each optionee to whom the prospectus is sent or given a copy of the Company's annual report to shareholders for its last fiscal year, unless such optionee otherwise has received a copy of such report. If the last fiscal year of the Company has ended within 120 days prior to the use of the prospectus, the annual report of the Company for the preceding fiscal year may be so delivered, but within such 120 day period the annual report for the last fiscal year will be furnished to each such optionee. The Company further undertakes to transmit or cause to be transmitted to all persons participating in the 1998 Plan or the 2006 Plan, who do not otherwise receive such material as shareholders of the Company, at the time and in the manner such material is sent to its shareholders, copies of all reports, proxy statements and other communications distributed to its shareholders generally. The Company hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Company's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. The Company undertakes to remove from registration by means of a post-effective amendment any of the registered securities which remain unsold at the termination of the offering. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the By-Laws or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

                  500,000 Shares of Common Stock
                  ------------------------------

Ladies and Gentlemen:

     We have acted as your counsel in connection with the registration  with the
Securities and Exchange  Commission (the "Commission") of 500,000 shares of your
Common  Stock,  $.01 par value per share (the  "Shares"),  that may be  acquired
under the Plan by participants in the Plan.

     In that  connection,  we have  examined  originals  or copies  certified or
otherwise  identified to our satisfaction of such documents,  corporate  records
and  other  instruments  as we have  deemed  necessary  or  appropriate  for the
purposes of this opinion. Based on the foregoing, we are of the opinion that the
Shares, when issued or delivered, and paid for as may be required, in accordance
with the provisions of the Plan, will have been validly issued and will be fully
paid and nonassessable. In rendering this opinion we have of course assumed that
the   certificates   evidencing  the  Shares  will  be  properly   executed  and
authenticated.

     We consent to the filing of this opinion with the  Commission as an exhibit
to the  Registration  Statement on Form S-8 for registration of the Shares under
the Securities Act of 1933, as amended,  and to the reference to us under "LEGAL
OPINION" in the Prospectus.


                                                     Very truly yours,

The Committee shall make all determinations of whether the Participant was Terminated for Cause. ARTICLE III ADMINISTRATION 3.1 Committee to Administer. (a) The Plan shall be administered by the Committee. The Committee shall have full discretionary power and authority to interpret, construe, and administer the Plan and to establish and amend rules and regulations for its administration. The Committee's decisions shall be final and conclusive with respect to the interpretation of the Plan and any Award made under it. (b) A majority of the members of the Committee shall constitute a quorum for the conduct of business at any meeting. The Committee shall act by majority vote of the members present at a duly convened meeting, including a telephonic meeting in accordance with Section 1708 of the Pennsylvania Business Corporation Law ("BCL"). Action may be taken without a meeting if written consent thereto is given in accordance with Section 1727 of the BCL. (c) Notwithstanding any provision herein to the contrary, to the extent the Board is performing any Plan-related functions, including the determination of whether a Participant has been Terminated for Cause, the Board shall have the same discretionary power and authority to administer the Plan as the Committee does under this Article III. 3.2 Powers of Committee. (a) Subject to the provisions of the Plan, the Committee shall have authority, in its discretion, to determine those Key Personnel and Directors who shall receive Awards, the time or times when each such Award shall be made, the type of Award to be made, and the number of shares to be subject to each Award. (b) A Director shall not participate in a vote granting himself an Award. (c) The Committee shall determine the terms, restrictions and provisions of the agreement relating to each Award. The Committee may correct any defect or supply any omission or reconcile any inconsistency in the Plan, or in any agreement relating to an Award, in such manner and to the extent the Committee shall determine in order to carry out the purposes and intent of the Plan, including Section 6.7. Unless prohibited by Code Section 409A (if applicable) or by any other applicable law, the Committee may, in its discretion, accelerate the date on which an Option may be exercised if the Committee determines that to do so will be in the best interests of the Company and the Participant. (d) Notwithstanding any provision herein to the contrary, to the extent the Board is performing any Plan-related functions, the Board shall have the same discretionary power and authority to administer the Plan as the Committee does under this Article III. 3.3 Awards. Awards under the Plan shall consist of Options and Restricted Stock Awards. All Awards shall be subject to the terms and conditions of the Plan and to such other terms and conditions consistent with the Plan as the Committee deems appropriate. Awards need not be uniform. 3.4 Eligibility for Awards. Awards may be made to Key Personnel and Directors. In selecting Participants and in determining the form and amount of the Award, the Committee may give consideration to his functions and responsibilities, his present and potential contributions to the success of the Company, the value of his services to the Company, and other factors deemed relevant by the Committee. ARTICLE IV STOCK OPTIONS 4.1 Award of Stock Options. The Committee may, from time to time, subject to Section 3.2(b) and other provisions of the Plan and such terms and conditions as the Committee may prescribe, grant Options to any Key Personnel or Directors. 4.2 Period of Option. (a) Except as provided in the remaining subsections of this Section 4.2 or in the Stock Option Agreement, an Option shall be exercisable only after twelve (12) months have elapsed from the date of grant, and after such twelve-month waiting period, the Option may be exercised in cumulative installments in the following manner: (i) The Participant may purchase up to one-fourth (1/4) of the total optioned shares at any time after one year from the date of grant and prior to the termination of the Option. (ii) The Participant may purchase an additional one-fourth (1/4) of the total optioned shares at any time after two years from the date of grant and prior to the termination of the Option. (iii) The Participant may purchase an additional one-fourth (1/4) of the total optioned shares at any time after three years from the date of grant and prior to the termination of the Option. (iv) The Participant may purchase an additional one-fourth (1/4) of the total optioned shares at any time after four years from the date of grant and prior to the termination of the Option. The duration of each Option shall not be more than ten (10) years from the date of grant. (b) Notwithstanding the foregoing, the Committee may establish, in the applicable Stock Option Agreement, any other period during which Options may be exercised. (c) Except as otherwise provided in Sections 4.6, 4.7, and 4.8 of the Plan or in the Stock Option Agreement, an Option may not be exercised by a Participant, other than a non-employee Director, unless such Participant is then, and continually (except for approved sick leave, FMLA, authorized military service, or other approved, bona fide leave of absence) after the grant of the Option has been, an officer or employee of the Company or a Subsidiary. (d) An Option granted to a non-employee Director, who is a Director at the time of such grant, shall be immediately exercisable, except as may be otherwise provided in the Option Agreement. 4.3 Stock Option Agreement. Each Option shall be evidenced by a Stock Option Agreement in such form and containing such terms and conditions as the Committee from time to time shall approve, except that the terms and conditions in the Stock Option Agreement shall be consistent with those set forth herein. 4.4 Option Price and Exercise. (a) The Option Price of Stock under each Option shall be determined by the Committee, except that, in no event, may the Option Price be less than the Fair Market Value (as defined under Article II of this Plan) of the Stock on the date on which the Option is granted. Once an Option is granted, repricing of the Option Price for an outstanding Option, whether exercisable or not exercisable, shall not be permitted. (b) Options may be exercised from time to time by giving written notice of exercise to the Company specifying the number of shares to be purchased. The notice of exercise shall be accompanied by (i) payment in full of the Option Price in cash, certified check, or other medium accepted by the Company, in its sole discretion, or (ii) a copy of irrevocable instructions to a broker to promptly deliver to the Company the amount of sale or loan proceeds sufficient to cover the Option Price. An Option shall be deemed exercised on the date the Company receives the notice of exercise and all the requirements of this Section 4.4(b) have been fulfilled. 4.5 Delivery of Option Shares. The Company shall not be obligated to deliver any Stock upon the exercise of an Option unless and until, in the opinion of the Company's counsel, all applicable federal, state and other laws and regulations have been complied with. In the event the outstanding Stock is at the time listed on any stock exchange, no delivery shall be made unless and until the shares to be delivered have been listed or authorized to be added to the list upon official notice of issuance on such exchange. No delivery shall be made until all other legal matters in connection with the issuance and delivery of Stock have been approved by the Company's counsel. Without limiting the generality of the foregoing, the Company may require from the Participant or other person purchasing shares of Stock under the Plan such investment representation or such agreement, if any, as counsel for the Company may consider necessary in order to comply with the Securities Act of 1933, as amended, and the regulations thereunder. Certificates evidencing the shares may be required to bear a restrictive legend. A stop transfer order may be required to be placed with the transfer agent, and the Company may require that the Participant or such other person agree that any sale of the shares will be made only on one or more specified stock exchanges or in such other manner as permitted by the Committee. 4.6 Termination of Service. (a) Except as otherwise provided in this Plan or in the applicable Stock Option Agreement, if the service of a Participant, other than as a non-employee Director, terminates for any reason other than death, permanent Disability or retirement with the consent of the Company, all Options held by the Participant shall expire and may not thereafter be exercised. For purposes of this section, the employment or other service in respect to Options held by such a Participant shall be treated as continuing intact while the Participant is on authorized military leave, FMLA, approved sick leave, or other approved, bona fide leave of absence (such as temporary employment with the government) if the period of such leave does not exceed 90 days, or, if longer, so long as the Participant's right to reestablish his service with the Company is guaranteed either by statute or by contract. Where the period of leave exceeds 90 days and where such Participant's right to reestablish his service is not guaranteed by statute or by contract, his service, in the Committee's sole discretion, shall be deemed to have terminated on the ninety-first day of such leave. Notwithstanding anything herein to the contrary, and unless the Stock Option Agreement provides otherwise, if the service of a Participant, other than as a non-employee Director, terminates, other than due to a Termination for Cause, the Participant may exercise all unexercised and vested Options within 30 days of such termination. Any Options in which such Participant is not vested at the time of his termination shall be forfeited. Except as so exercised, such Option shall expire at the end of such period. In no event, however, may any Option be exercised after the expiration of ten (10) years from the date of grant of such Option. (b) Except as otherwise provided in the Stock Option Agreement, a non-employee Director whose service is terminated shall be entitled to exercise his Option until the expiration of the full term of the Option, unless the non-employee Director has been Terminated for Cause. In the event that a non-employee Director is Terminated for Cause, all Options held by such Director shall terminate immediately and may not thereafter be exercised. 4.7 Death. Except as otherwise provided in the Stock Option Agreement and except with respect to non-employee Directors as provided in Section 4.6(b), during the twelve (12) month period following the Participant's death, any or all of the unexercised and vested Options that the Participant was entitled to exercise immediately prior to his death may be exercised by such Participant's executor, administrator, or the person(s) to whom the Options are transferred by will or the applicable laws of descent and distribution. Any Options in which such Participant is not vested at the time of his death shall be forfeited. In no event, however, may any such Option be exercised after the expiration of ten (10) years from the date of grant of such Option. 4.8 Retirement or Disability. Except as otherwise provided in the applicable Stock Option Agreement and except with respect to non-employee Directors as provided in Section 4.6(b), if a Participant retires from service with the consent of the Company, or suffers Disability, at a time when he is entitled to exercise an Option, then at any time or times within three years after his termination of service because of such retirement or Disability the Participant may exercise such Option as to all or any of the shares which he was entitled to purchase under the Option immediately prior to such termination. Except as so exercised, such Option shall expire at the end of such period. In no event, however, may any Option be exercised after the expiration of 10 years from the date of grant of such Option. 4.9 Committee Discretion. The Committee shall have authority to determine whether or not a Participant (including a non-employee Director) has retired from service with the Company's consent, resigned or has suffered a Disability, and its determination shall be binding on all concerned. In the sole discretion of the Committee, a transfer of service to an affiliate of the Company other than a Subsidiary (the latter type of transfer not constituting a termination of service for purposes of the Plan) may be deemed to be a retirement from service with the consent of the Company so as to entitle the Participant to exercise the Option within 90 days after such transfer. 4.10 Stockholder Rights and Privileges. A Participant shall have no rights as a shareholder with respect to any Stock covered by an Option until the issuance of a stock certificate to the Participant representing such Stock. ARTICLE V RESTRICTED STOCK AWARDS 5.1 Grant of Restricted Stock Awards. In its sole discretion, the Committee may elect to grant a Restricted Stock Award to any Key Personnel and/or Director, including but not limited to grants derived from participation in another plan, program or arrangement established or maintained by the Company or its Subsidiaries. Notwithstanding anything in this Plan to the contrary, the Committee, in its discretion, may determine that a Restricted Stock Award granted pursuant to another plan, program or arrangement established or maintained by the Company will not be forfeitable when issued, but may be subject to such other terms, conditions and restrictions (including but not limited to restrictions on the sale of stock for a two year, or other appropriate, period), as set forth in the Award Agreement. 5.2 Vesting Requirements. The restrictions imposed on Stock granted under a Restricted Stock Award shall lapse in accordance with the vesting requirements specified by the Committee in the Restricted Stock Agreement, provided that the Committee, subject to Section 6.7 and Code Section 83, may accelerate the vesting of a Restricted Stock Award at any time. Such vesting requirements may be based on the continued service of the Participant with the Company or its affiliates for a specified time period (or periods), on the attainment of specified performance goals established by the Committee in its discretion, or on any other condition creating a substantial risk of forfeiture under Code Section 83. If the vesting requirements of a Restricted Stock Award are not satisfied, the Award shall be forfeited and the Stock subject to the Award shall be returned to the Company. 5.3 Restrictions. Stock granted under any Restricted Stock Award may not be transferred, assigned or subject to any encumbrance, pledge or charge until all applicable restrictions are removed or have expired, unless otherwise permitted by the Committee. Failure to satisfy any applicable restrictions shall result in the subject Stock being forfeited and returned to the Company. The Committee may require in a Restricted Stock Agreement that certificates representing the Stock granted under a Restricted Stock Award bear a legend making appropriate reference to the restrictions imposed, and that certificates representing the Stock granted or sold under a Restricted Stock Award will remain in the physical custody of an escrow holder until all restrictions are removed or have expired. 5.4 Rights as a Shareholder. Subject to the foregoing provisions of this Article V and the applicable Restricted Stock Agreement, the Participant shall have all rights of a shareholder with respect to the Stock granted to the Participant under a Restricted Stock Award, including the right to vote the Stock and receive all dividends and other distributions paid or made with respect thereto. The Committee may provide in a Restricted Stock Agreement for the payment of dividends and distributions to the Participant at such times as paid to shareholders generally or at the times of vesting or other payment of the Restricted Stock Award. Notwithstanding the foregoing, if the Committee determines that the payment of dividends at any time would invoke application of Code Section 409A and Section 6.7, the Participant shall not have any right to receive dividends and distributions related to such Restricted Stock. 5.5 Restricted Stock Awards to Outside Directors. In addition to discretionary Restricted Stock Awards under Section 5.1, and subject to adjustment in accordance with Section 6.6, commencing on May 24, 2006, each non-employee Director, elected at an annual meeting of the Company's shareholders, shall be awarded 3,500 shares of Stock as of each date he is elected (or re-elected). Each such Award shall be a Restricted Stock Award subject to such terms and restrictions as shall be approved by the Committee. 5.6 Section 83(b) Election. If a Participant makes an election pursuant to Code Section 83(b) with respect to a Restricted Stock Award, the Participant shall file, within 30 days following the date of grant, a copy of such election with the Company and with the Internal Revenue Service in accordance with the regulations under Code Section 83. The Committee may provide in a Restricted Stock Agreement that the Restricted Stock Award is conditioned upon the Participant's making or refraining from making an election with respect to the Award under Code Section 83(b). 5.7 Compliance with Securities Laws. Section 4.5 shall apply to all Restricted Stock Awards. ARTICLE VI MISCELLANEOUS PROVISIONS 6.1 Nontransferability. No Award under the Plan shall be transferable by the Participant other than by will or the laws of descent and distribution. Except as provided in Section 4.7, all Options shall be exercisable during the Participant's lifetime only by such Participant or his Personal Representative. Any transfer contrary to this Section 6.1 will nullify the Award. 6.2 Amendments. The Committee may at any time discontinue granting Awards under the Plan. The Board may at any time amend the Plan or amend any outstanding Award Agreement 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 no such amendment shall be permissible if it would result in Rule 16b-3 under the Securities Exchange Act of 1934, as amended, becoming inapplicable to any Award. 6.3 Termination. The Board may terminate the Plan at any time prior to its scheduled expiration date, but no such termination shall adversely affect the rights of any Participant under any Award theretofore granted in which he has a vested interest without his written consent. 6.4 Nonuniform Determinations. The Committee's determinations under the Plan, including without limitation (i) the determination of the Key Personnel and Directors to receive Awards, (ii) the form, amount and timing of such Awards, (iii) the terms and provisions of such Awards and (iv) the Agreements evidencing the same, need not be uniform and may be made by it selectively among Key Personnel and Directors who receive, or who are eligible to receive, Awards under the Plan, whether or not such Key Personnel or Directors are similarly situated. 6.5 No Right to Employment. Neither the action of the Board in establishing the Plan, nor any action taken by the Committee under the Plan, nor any provision of the Plan, shall be construed as giving to any person the right to be retained in the employ, or as an officer or Director, of the Company or any Subsidiary. 6.6 Changes in Stock. In the event of a stock dividend, split-up, or a combination of shares, recapitalization or merger in which the Company is the surviving corporation or other similar capital change, the number and kind of shares of stock or securities of the Company to be subject to the Plan and to Options or Stock then outstanding or to be awarded thereunder, the maximum number of shares of stock or securities which may be issued on the exercise of Options granted under the Plan, the Option Price and other relevant provisions shall be appropriately adjusted by the Board, whose determination shall be binding on all persons. In the event of a consolidation or a merger in which the Company is not the surviving corporation, or any other merger in which the shareholders of the Company exchange their shares of stock in the Company for stock of another corporation, or in the event of complete liquidation of the Company, or in the case of a tender offer accepted by the Board of Directors, all outstanding Options shall thereupon terminate, provided that the Board may, prior to the effective date of any such consolidation or merger, either (i) make all outstanding Options immediately exercisable or (ii) arrange to have the surviving corporation grant to the Participants replacement Options on terms which the Board shall determine to be fair and reasonable. 6.7 Compliance with Code Section 409A. This Plan does not provide for the deferral of compensation, as defined under Code Section 409A and applicable regulations. Accordingly, this Plan is specifically not subject to Code Section 409A and its requirements. However, if Code Section 409A is determined to apply to any Award made under the Plan, the provisions of the Plan applicable to such Awards shall be administered in a manner consistent with Code Section 409A. Further, any provision that would cause the Plan or any Award to fail to satisfy Code Section 409A shall have no force and effect until amended to comply with Code Section 409A (which amendment may be retroactive to the extent permitted by Code Section 409A and may be made by the Company without the consent of Participants). All references in this Plan to Code Section 409A shall include any proposed, temporary or final regulations, or any other guidance, promulgated with respect to Code Section 409A by the U.S. Department of the Treasury or the Internal Revenue Service. 6.8 Tax Withholding. Whenever Stock is to be delivered to a Participant upon exercise of an Option or the award of a Restricted Stock Award, the Company may (i) require such Participant to remit to the Company an amount in cash sufficient to satisfy all federal, state and local tax withholding requirements related thereto, (ii) withhold such required withholding from compensation otherwise due to such Participant, (iii) any combination of the foregoing, or (iv) any other acceptable method approved by the Company, including a netting of Stock, provided such approach is permissible under applicable securities and other laws. 6.9 Status. A Participant's status as Key Personnel or a Director shall be made exclusively by the Committee and determined for each Award as of the date the Award is granted to the Participant. * * * * * * * *
