Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

Set forth below is a description of certain provisionsof (i) the Pennsylvania 
Business Corporation Law (the PBCL), (ii) the Company's Second Amended and 
Restated Articles ofIncorporation (the Company Articles), (iii) the Company's 
Sixth Amended and Restated Bylaws (the Company Bylaws) and (iv) indemnificationa
greements the Company has entered into with its directors and all of its 
executive officers (the Indemnification Agreements). This descriptionis 
intended as a summary only and is qualified in its entirety by reference to 
the PBCL, the Company Articles, the Company Bylaws andthe Indemnification 
Agreements.

Under Sections 1741 and 1742 of the PBCL, a businesscorporation has the power 
to indemnify any person who was or is a party, or is threatened to be made a 
party, to any threatened, pendingor completed action or proceeding, whether 
civil, criminal, administrative or investigative, by reason of the fact that 
such person isor was a director, officer or representative of the corporation, 
or is or was serving at the request of the corporation as a director,officer 
or representative of another corporation or other enterprise, against expenses 
(including attorneys' fees), judgments, finesand amounts paid in settlement 
actually and reasonably incurred by such person in connection with such action 
or proceeding, if such personacted in good faith and in a manner he or she 
reasonably believed to be in, or not opposed to, the best interests of the 
corporation,and, with respect to any criminal proceeding, had no reasonable 
cause to believe his or her conduct was unlawful. In the case of a 
threatened,pending or completed action or proceeding by or in the right of the 
corporation, such indemnification only covers expenses and excludesjudgments 
and amounts paid in settlement with respect to such action or proceeding, and 
no indemnification can be made for expenses ifsuch person has been adjudged to 
be liable to the corporation unless, and only to the extent that, a court 
determines upon applicationthat, despite the adjudication of liability but in 
view of all the circumstances, such person is fairly and reasonably entitled 
to indemnityfor the expenses that the court deems proper.

In addition, PBCL Section 1744 provides that,unless ordered by a court, any 
indemnification referred to above shall be made by the corporation only as 
authorized in the specific caseupon a determination that indemnification is 
proper in the circumstances because the indemnitee has met the applicable 
standard of conduct.Such determination shall be made:

(1)            bythe Company's board of directors by a majority vote of a 
quorum consisting of directors who were not parties to the action or 
proceeding~

(2)            ifsuch a quorum is not obtainable, or if obtainable and a 
majority vote of a quorum of disinterested directors so directs, by 
independentlegal counsel in a written opinion~ or

(3)            bythe shareholders.


                                       3                                        


Notwithstanding the above, PBCL Section 1743 provides that tothe extent that a 
present or former director or officer of a business corporation is successful 
on the merits or otherwise in defenseof any action or proceeding referred to 
above, or in defense of any claim, issue or matter therein, the director or 
officer shall be indemnifiedagainst expenses (including attorneys' fees) 
actually and reasonably incurred by the director of officer in connection 
therewith.

Further, PBCL Section 1745 provides that expenses(including attorneys' fees) 
incurred by an officer, director or representative of a business corporation 
in defending any such actionor proceeding may be paid by the corporation in 
advance of the final disposition of the action or proceeding upon receipt of 
an undertakingby or on behalf of such officer, director or representative to 
repay the amount advanced if it is ultimately determined that the indemniteeis 
not entitled to be indemnified by the corporation.

Also, PBCL Section 1746 provides that theindemnification and advancement of 
expenses provided by, or granted pursuant to, the foregoing provisions is not 
exclusive of any otherrights to which a person seeking indemnification or 
advancement of expenses may be entitled under any bylaw, agreement, vote of 
shareholdersor disinterested directors or otherwise, and that indemnification 
may be granted under any bylaw, agreement, vote of shareholders or directorsor 
otherwise for any action taken or any failure to take any action and may be 
made whether or not the corporation would have the powerto indemnify the 
person under any other provision of law and whether or not the indemnified 
liability arises or arose from any threatened,pending or completed action by 
or in the right of the corporation~ provided, however, that no indemnification 
may be made in anycase where the act or failure to act giving rise to the 
claim for indemnification is determined by a court to have constituted 
willfulmisconduct or recklessness.

Article IV of the Company Bylaws providesthat the Company's directors or 
officers shall be indemnified as of right to the fullest extent not prohibited 
by law in connectionwith any actual or threatened action, suit or proceeding, 
civil, criminal, administrative, investigative or other (whether brought byor 
in the right of the corporation or otherwise) arising out of their service to 
the Company or to another corporation or other enterpriseat the Company's 
request; provided, however, that the Company shall not indemnify any director 
or officer in connection with a proceeding(or part thereof) initiated by such 
director or officer (other than a proceeding to enforce such person's rights 
to indemnificationunder the provisions of Article IV) unless such proceeding 
(or part thereof) was authorized by the Company's board of directors.

PBCL Section 1747 permits a business corporationto purchase and maintain 
insurance on behalf of any person who is or was a director, officer or 
representative of the corporation, oris or was serving at the request of the 
corporation as a director, officer or representative of another corporation or 
other enterprise,against any liability asserted against such person and 
incurred by him or her in any such capacity, or arising out of his or her 
statusas such, whether or not the corporation would have the power to 
indemnify the person against such liability under the provisions describedabove.


Article IVof the Company Bylaws provides that the Company may purchase and 
maintain insurance to protect the Company and any
director, officer,agent or employee against any liability asserted against 
such person and incurred by such person in respect of the service of such 
person,whether or not the Company would have the power to indemnify such 
person against such liability by law or under the provisions of Article 
IV.Article IV is applicable to persons who have ceased to be directors, 
officers, agents, and employees and shall inure to the benefitof the heirs, 
executors and administrators of persons entitled to indemnity.

The Company maintains directors' and officers'liability insurance covering its 
directors and officers with respect to liabilities, including liabilities 
under the Securities Act, whichthey may incur in connection with their serving 
as such. Under this insurance, the Company may receive reimbursement for 
amounts as towhich the directors and officers are indemnified by the Company 
under the bylaw indemnification provisions described above. Such insurancealso 
provides certain additional coverage for the directors and officers against 
certain liabilities even though such liabilities maynot be covered by the 
bylaw indemnification provisions described above.

Aspermitted by PBCL Section 1713, the Company Articles and the Company Bylaws 
provide that no director shall be personally liable formonetary damages as such

(except to the extent otherwise provided by law) for any action taken, or 
failure to take any action,unless the director has breached or failed to 
perform the duties of his or her office under Subchapter B-"Fiduciary Duty"of 
Chapter 17 of the PBCL (or any successor statute relating to directors' 
standard of care and justifiable reliance), and suchdirector's breach of duty 
or failure to perform constituted self-dealing, willful misconduct or 
recklessness. The PBCL states thatthis exculpation from liability does not 
apply to the responsibility or liability of a director pursuant to any 
criminal statute or theliability of a director for the payment of taxes 
pursuant to federal, state or local law. It is uncertain whether this 
provision willcontrol with respect to liabilities imposed upon directors by 
federal law, including federal securities laws.


                                       4                                        


Aspermitted by PBCL Section 1735, the Company's Bylaws provide that no
officer shallbe personally liable, as such, for monetary damages (except to 
the extent otherwise provided by law) for any action taken, or any failureto 
take any action, unless such officer has breached or failed to perform the 
duties of his or her office under Title 15, Chapter 17,Subchapter C of the 
Pennsylvania Consolidated Statutes (or any successor statute relating to 
officers' standard of care and justifiablereliance), and the breach or failure 
to perform constitutes self-dealing, willful misconduct or recklessness. The 
PBCL states that thisexculpation from liability does not apply to the 
responsibility or liability of an officer pursuant to any criminal statute or 
the liabilityof an officer for the payment of taxes pursuant to federal, state 
or local law. It is uncertain whether this provision will control withrespect 
to liabilities imposed upon directors by federal law, including federal 
securities laws.

The Company has Indemnification Agreements withall of its executive officers 
and directors (collectively, indemnitees). These Indemnification Agreements 
provide that the indemniteeswill be protected as promised in the Company 
Bylaws (regardless of, among other things, any amendment to or revocation of 
the CompanyBylaws or any change in the composition of the Company's board of 
directors or an acquisition transaction relating to the Company)and advanced 
expenses to the fullest extent of the law and as set forth in the 
Indemnification Agreements. These Indemnification Agreementsalso provide, to 
the extent insurance is maintained, for the continued coverage of the 
indemnitees under the Company's directorand officer insurance policies. The 
Indemnification Agreements, among other things and subject to certain 
limitations, indemnify and holdharmless the indemnitees against any and all 
reasonable expenses, including fees and expenses of counsel, and any and all 
liability andloss, including judgments, fines, ERISA, excise taxes or 
penalties and amounts paid or to be paid in settlement, incurred or paid by 
theindemnitees in connection with any threatened, pending or completed action, 
suit or proceeding, whether civil, criminal, administrativeor investigative 
and whether or not by or in the right of the corporation or otherwise, in 
which the indemnitees are, were or at any timebecome parties, or are 
threatened to be made parties or are involved by reason of the fact that the 
indemnitees are or were the Company'sdirectors or officers or are or were 
serving at the Company's request as directors, officers, employees, trustees 
or representativesof another corporation or enterprise.

the effective date of the Registration Statements (or the most recent 
post-effectiveamendment thereof) which, individually or in the aggregate, 
represent a fundamental change in the information set forth in the 
RegistrationStatements. Notwithstanding the foregoing, any increase or 
decrease in volume of securities offered (if the total dollar value of

deviation from the low or high end of the estimated maximum offering rangemay 
be reflected in the form of a prospectus filed with the Commission pursuant to 
Rule 424(b) if, in the aggregate, the changesin volume and price represent no 
more than a 20% change in the maximum aggregate offering price set forth in 
the "Calculation ofRegistration Fee" table in the effective registration

paragraphs is contained in reports filed with or furnished to the Commission 
by the registrant pursuantto Section 13 or Section 15(d) of the Exchange Act 
that are incorporated by reference in the Registration Statements.

(2)            That,for the purpose of determining any liability under the 
Securities Act, each such post-effective amendment shall be deemed to be a 
newregistration statement relating to the securities offered therein, and the 
offering of such securities at that time shall be deemed tobe the initial

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 counselthe 
matter has been settled by controlling precedent, submit to a court of 
appropriate jurisdiction the question whether such indemnificationby it is 
against public policy as expressed in the Securities Act and will be governed 
by the final adjudication of such issue.
