#### ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission (the "SEC") using a "shelf" registration process. Under this shelf registration process, we may sell any combination of the securities described in this prospectus as being offered, from time to time in one or more offerings, up to a total dollar amount of $200,000,000.

This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about all of the terms of that offering. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to that offering. The applicable prospectus supplement (and any related free writing prospectus that we may authorize to be provided to you) may also add, update or change information contained in this prospectus or in the documents that we have incorporated by reference. This prospectus does not contain all of the information set forth in the registration statement and the exhibits to the registration statement. You should read this prospectus and the applicable prospectus supplement and any related free writing prospectus together with additional information from the sources described in "Where You Can Find More Information" and "Incorporation of Certain Documents by Reference" in this prospectus. You should not assume that the information in this prospectus, the prospectus supplements, any free writing prospectus or any document incorporated by reference is accurate as of any date other than the date of the applicable document.

You should rely only on the information provided or incorporated by reference in this prospectus, any free writing prospectus and any prospectus supplement, if applicable. We have not authorized anyone to provide you with different information.

References to "we," "us," "our," "Orrstown" or the "Company" refer to Orrstown Financial Services, Inc. and its directly or indirectly owned subsidiaries, unless the context otherwise requires. The term "you" refers to a prospective investor.

#### CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain of the statements made in this prospectus, including information incorporated herein by reference to other documents, are "forward-looking statements" within the meaning and protections of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

Forward-looking statements include statements with respect to our beliefs, plans, objectives, goals, expectations, anticipations, assumptions, estimates, intentions, and future performance, and involve known and unknown risks, uncertainties and other factors, which may be beyond our control, and which may cause our actual results, performance or achievements to be materially different from future results, performance or achievements expressed or implied by such forward-looking statements.

------

[*Table of Contents*](#TABLEOFCONTENTS)

All statements other than statements of historical fact are statements that could be forward-looking statements. You can identify these forward-looking statements through our use of words such as "may", "will", "anticipate", "assume", "should", "indicate", "would", "believe", "contemplate", "expect", "estimate", "continue", "plan", "point to", "project", "could", "intend", "target", and other similar words and expressions of the future. These forward-looking statements may not be realized due to a variety of factors, including, without limitation, statements related to new business development, new loan opportunities, growth in the balance sheet and fee-based revenue lines of business, merger and acquisition activity, cost savings initiatives, reducing risk assets, and mitigating losses in the future. Accordingly, the Company cautions you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. Although the Company believes that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements and there can be no assurances that the Company will achieve the desired level of new business development and new loans, growth in the balance sheet and fee-based revenue lines of business, cost savings initiatives, and continued reductions in risk assets or mitigate losses in the future. Factors which could cause the actual results to differ from those expressed or implied by the forward-looking statements include, but are not limited to, the following: interest rate changes or volatility; general economic conditions (including inflation and concerns about liquidity) on a national basis or in the local markets in which the Company operates; ineffectiveness of the Company's strategic growth plan due to changes in current or future market conditions; the effects of competition and how it may impact our community banking model, including industry consolidation and development of competing financial products and services; changes in consumer behavior due to changing political, business and economic conditions, or legislative or regulatory initiatives; changes in, and evolving interpretations of, existing and future laws and regulations; changes in credit quality; inability to raise capital, if necessary, under favorable conditions; volatility in the securities markets; the demand for our products and services; deteriorating economic conditions; the impact of tariffs and the U.S. federal government shutdown; geopolitical tensions; operational risks including, but not limited to, cybersecurity incidents, fraud, natural disasters and future pandemics; expenses associated with litigation and legal proceedings; and other risks and uncertainties, including those detailed in our Annual Report on Form 10-K for the year ended December 31, 2024, and our Quarterly Reports on Form 10-Q under the sections titled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" and in other filings made with the SEC.

**Because such forward-looking statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such statements. The foregoing factors are not exclusive and you are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this document or, in the case of documents incorporated by reference, the dates of those documents. We do not undertake to update any forward-looking statements, whether written or oral, that may be made from time to time by or on behalf of us.**

#### RISK FACTORS

Investing in our securities involves risk. You should carefully consider the specific risks set forth in "Risk Factors" in the applicable prospectus supplement and any related free writing prospectus and under the caption "Risk Factors" in any of our filings with the SEC, including our most recent Annual Report on Form 10-K, and in all other information appearing in this prospectus or incorporated by reference into this prospectus and any applicable prospectus supplement. For additional information, please see the sources described in "Where You Can Find More Information."

These risks are not the only risks we face. Additional risks not presently known to us, or that we currently view as immaterial, may also impair our business. If any of the risks described in our SEC filings or any prospectus supplement or any additional risks actually occur, our business, financial condition, results of operations and cash flows could be materially and adversely affected. In that case, the value of our securities could decline substantially and you could lose all or part of your investment.

#### USE OF PROCEEDS

We will retain broad discretion over the use of the net proceeds from the sale of the securities offered hereby. Unless otherwise specified in the applicable prospectus supplement or any related free writing prospectus, we currently expect to use the net proceeds of our sale of securities for general corporate purposes.

General corporate purposes may include, among other purposes, contribution to the capital of our bank subsidiary to support its lending and investing activities; repayment of our debt; redemption of our capital stock; to support or fund acquisitions of other institutions or branches if opportunities for such transactions become available; and other permitted activities. We may temporarily invest funds that we do not immediately need for these purposes in investment securities or use them to make payments on our borrowings.

------

[*Table of Contents*](#TABLEOFCONTENTS)

#### DESCRIPTION OF COMMON STOCK

#### <br>
The following is a description of our common stock, certain provisions of our amended articles of incorporation and amended by-laws and certain provisions of applicable law. The following is qualified by applicable law and by the provisions of our amended articles of incorporation and by-laws, copies of which have been filed with the SEC and are also available upon request from us. You should read the prospectus supplement, which will contain additional information and which may update or change some of the information below.

#### Authorized Shares

Our articles of incorporation provide that we may issue up to 50,000,000 shares of common stock, no par value, and 500,000 shares of preferred stock, par value $1.25 per share.

#### Shareholder Liability

All outstanding shares of our common stock are fully paid and nonassessable. Under the Pennsylvania Business Corporation Law of 1988, as amended, shareholders generally are not personally liable for a corporation's acts or debts.

#### Dividends; Liquidation; Dissolution

Subject to the preferential rights of any other shares or series of capital stock, holders of shares of Orrstown common stock are entitled to receive dividends on shares of common stock if, as and when authorized and declared by the Orrstown board of directors out of funds legally available for dividends and to share ratably in the assets of the Company legally available for distribution to its shareholders in the event of its liquidation, dissolution or winding-up after payment of, or adequate provision for, all known debts and liabilities of the Company.

#### Voting Rights

Each outstanding share of Orrstown common stock entitles the holder to one vote on all matters submitted to a vote of shareholders, including the election of directors. Unless a larger vote is required by law, the Company's articles of incorporation or its bylaws, when a quorum is present at a meeting of shareholders, a majority of the votes properly cast upon any question other than the election of directors shall decide the question. A plurality of the votes properly cast for the election of a person to serve as a director shall elect such person. Except as otherwise required by law or except as provided with respect to any other class or series of capital stock, the holders of Orrstown common stock possess the exclusive voting power. There is no cumulative voting in the election of directors. The Orrstown board is classified into three classes with each class as nearly equal in number as possible. This means, in general, that one-third of the members of the board are subject to reelection at each annual meeting of shareholders.

#### Preemptive Rights; Redemption

Holders of Orrstown common stock have no conversion, sinking fund or redemption rights or preemptive rights to subscribe for any of Orrstown's classes of stock.

#### Anti-Takeover Provisions

*Articles of Incorporation and By-Laws*

Orrstown's articles of incorporation and bylaws contain certain provisions that may have the effect of deterring or discouraging an attempt to take control of the Company. Among other things, these provisions:

<br> • empower our board of directors, without shareholder approval, to issue shares of Orrstown preferred stock the terms of which, including voting power, are set by Orrstown's board;

<br> • divide our board of directors into three classes serving staggered three-year terms;

------

[*Table of Contents*](#TABLEOFCONTENTS)

<br> • authorize our board of directors to oppose a tender or other offer for the Company's securities if the board of directors determines that such an offer should be rejected;

<br> • restrict the ability of shareholders to remove directors;

• require that shares with at least 75% or, in certain circumstances, a majority of total voting power, approve certain transactions with significant beneficial owners of Orrstown common stock;

• require that shares with at least 75% or, in certain circumstances, a majority of total voting power, approve the repeal or amendment of certain provisions of Orrstown's articles of incorporation;

• require that, following any acquisition by any person or group of 10% of Orrstown's voting power, in the case of any business combination with such person or an entity directly or indirectly controlled by such person, the remaining shareholders have the right to receive for their shares from such person at least the highest price paid by such person for any of the shares then directly or indirectly owned by such person;

<br> • eliminate cumulative voting in the election of directors;

<br> • require advance notice of nominations for the election of directors and the presentation of shareholder proposals at meetings of shareholders; and

<br> • provide for certain director eligibility requirements, including that each member of the board hold at least 5,000 shares of the Company's common stock.

*Pennsylvania Business Corporation Law*

The Pennsylvania Business Corporation Law of 1988, as amended, also contains certain provisions applicable to Orrstown that may have the effect of deterring or discouraging an attempt to take control of the Company. These provisions, among other things:

• prohibit for five years, subject to certain exceptions, a "business combination" (which includes a merger or consolidation of the corporation or a sale, lease or exchange of assets) with a person or group beneficially owning 20% or more of a public corporation's voting power (Subchapter 25F of the Business Corporation Law);

• prevent a person or group acquiring different levels of voting power (20%, 33% and 50%) from voting any shares over the applicable threshold, unless "disinterested shareholders" approve such voting rights (Subchapter 25G of the Business Corporation Law);

• require any person or group that publicly announces that it may acquire control of a corporation, or that acquires or publicly discloses an intent to acquire 20% or more of the voting power of a corporation, to disgorge to the corporation any profits that it receives from sales of the corporation's equity securities purchased over the prior 18 months (Subchapter 25H of the Business Corporation Law);

<br> • expand the factors and groups (including shareholders) which a corporation's board of directors can consider in determining whether an action is in the best interests of the corporation;

<br> • provide that a corporation's board of directors need not consider the interests of any particular group as dominant or controlling;

• provide that a corporation's directors, in order to satisfy the presumption that they have acted in the best interests of the corporation, need not satisfy any greater obligation or higher burden of proof with respect to actions relating to an acquisition or potential acquisition of control;

• provide that actions relating to acquisitions of control that are approved by a majority of "disinterested directors" are presumed to satisfy the directors' fiduciary duty, unless it is proven by clear and convincing evidence that the directors did not assent to such action in good faith after reasonable investigation; and

------

[*Table of Contents*](#TABLEOFCONTENTS)

<br> • provide that the fiduciary duty of a corporation's directors is solely to the corporation and may be enforced by the corporation or by a shareholder in a derivative action, but not by a shareholder directly.

The Pennsylvania Business Corporation Law also explicitly provides that the fiduciary duty of directors does not require them to:

<br> • redeem any rights under, or to modify or render inapplicable, any shareholder rights plan;

• render inapplicable, or make determinations under, provisions of the Pennsylvania Business Corporation Law relating to control transactions, business combinations, control-share acquisitions or disgorgement by certain controlling shareholders following attempts to acquire control; or

• act as the board of directors, a committee of the board or an individual director, solely because of the effect the action might have on an acquisition or potential acquisition of control of the corporation or the consideration that might be offered or paid to shareholders in such an acquisition.

The transfer agent and registrar for shares of our common stock is Continental Stock Transfer & Trust Company.

#### Securities Exchange

#### General

Our board of directors is authorized to issue up to 500,000 shares of preferred stock, par value $1.25 per share, in one or more series, without shareholder approval. Our board of directors has the discretion to determine the designations, rights, preferences, privileges, qualifications and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges, liquidation preferences and sinking fund terms, of each series of preferred stock, any or all of which may be greater than the rights of the common stock. The terms of any series of preferred stock designated by our board of directors will be set forth in a certificate of designation which we will include as an exhibit to the registration statement that includes this prospectus, or as an exhibit to a filing with the SEC that is incorporated by reference into this prospectus.

Unless we provide otherwise in a prospectus supplement, the preferred stock offered through that supplement will, with respect to dividend rights and rights upon our liquidation, dissolution or winding up, rank:

<br> • senior to all classes or series of our common stock, and to all other equity securities ranking junior to the offered shares of preferred stock;

<br> • on a parity with all of our equity securities ranking on a parity with the offered shares of preferred stock; and

<br> • junior to all of our equity securities ranking senior to the offered shares of preferred stock.

The term "equity securities" does not include convertible debt securities.

#### Voting Rights

Unless otherwise indicated in the applicable prospectus supplement, holders of our preferred stock will not have any voting rights, except as may be required by applicable law.

#### Dividends

Subject to any preferential rights of any outstanding stock or series of stock, our preferred shareholders are entitled to receive dividends, when and as authorized by our board of directors, out of legally available funds, as specified in the applicable prospectus supplement.

#### Redemption

If we provide for a redemption right in a prospectus supplement, the preferred stock offered through that supplement will be subject to mandatory redemption or redemption at our option, in whole or in part, in each case upon the terms, at the times and at the redemption prices set forth in that prospectus supplement.

[*Table of Contents*](#TABLEOFCONTENTS)

#### Liquidation Preference

In the event of our voluntary or involuntary dissolution, liquidation, or winding up, the holders of any series of our preferred stock will be entitled to receive, after distributions to holders of any series or class of our capital stock ranking senior, an amount equal to the stated or liquidation value of the shares of the series plus, if applicable, an amount equal to accrued and unpaid dividends. If the assets and funds to be distributed among the holders of our preferred stock will be insufficient to permit full payment to the holders, then the holders of our preferred stock will share ratably in any distribution of our assets in proportion to the amounts that they otherwise would receive on their shares of our preferred stock if the shares were paid in full.

#### Conversion Rights

The terms and conditions, if any, upon which any series of preferred stock is convertible into common stock or other securities will be set forth in the prospectus supplement relating to the offering of those shares of preferred stock. These terms typically will include number of shares of common stock or other securities into which the preferred stock is convertible; conversion price (or manner of calculation); conversion period; provisions as to whether conversion will be at the option of the holders of the preferred stock or at our option; events, if any, requiring an adjustment of the conversion price; and provisions affecting conversion in the event of the redemption of that series of preferred stock.

#### Transfer Agent and Registrar

We will identify the transfer agent and registrar for any series of preferred stock offered by this prospectus in a prospectus supplement.

#### DESCRIPTION OF DEPOSITARY SHARES

*The complete terms of the depositary shares will be contained in the deposit agreement and any related document applicable to any depositary shares. These documents have been or will be included or incorporated by reference as exhibits to the registration statement of which this prospectus is a part. You should read the deposit agreement and any related document. You should also read the prospectus supplement, which will contain additional information and which may update or change some of the information below.*

We may elect to offer fractional interests in shares of our preferred stock, in which case we will issue receipts for depositary shares and each of these depositary shares will represent a fraction of a share of the applicable series of our preferred stock, as set forth in the applicable prospectus supplement. The following summary of the terms of the depositary shares does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the terms of the depositary shares and our preferred stock, as well as the form of the deposit agreement and our Articles of Incorporation relating to the applicable series of our preferred stock that are, or will be, filed with the SEC. Therefore, you should carefully consider the actual provisions of these documents.

#### General

Each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in shares of our preferred stock underlying that depositary share, to all rights and preferences of our preferred stock underlying that depositary share. These rights may include dividend, voting, redemption and liquidation rights.

The shares of our preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary, under a deposit agreement between us, the depositary and the holders of the depositary receipts. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares. The name and address of the principal executive office of the depositary will be included in the prospectus supplement relating to the issue.

------

[*Table of Contents*](#TABLEOFCONTENTS)

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence and paying certain charges.

#### Dividends and Other Distributions

The depositary will distribute cash dividends or other cash distributions, if any, received in respect of the series of our preferred stock underlying the depositary shares to the record holders of depositary receipts in proportion to the number of depositary shares owned by those holders on the relevant record date. The relevant record date for depositary shares will be the same date as the record date for our preferred stock.

In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary receipts that are entitled to receive the distribution, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary, with our approval, may adopt another method for the distribution, including selling the property and distributing the net proceeds to the holders.

#### Liquidation Preference

If a series of our preferred stock underlying the depositary shares has a liquidation preference, in the event of our voluntary or involuntary liquidation, dissolution or winding up, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of our preferred stock, as set forth in the applicable prospectus supplement.

#### Redemption

If a series of our preferred stock underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of our preferred stock held by the depositary. Whenever we redeem any of our preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing our preferred stock so redeemed. The depositary will mail the notice of redemption to the record holders of the depositary receipts promptly upon receiving the notice from us.

After the date fixed for redemption, the depositary shares called for redemption will no longer be outstanding. When the depositary shares are no longer outstanding, all rights of the holders will end, except the right to receive money, securities or other property payable upon redemption.

#### Voting

Upon receipt of notice of any meeting at which the holders of our preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts underlying our preferred stock. Each record holder of those depositary receipts on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of our preferred stock underlying that holder's depositary shares. The record date for the depositary will be the same date as the record date for our preferred stock. The depositary will try, as far as practicable, to vote our preferred stock underlying the depositary shares in accordance with these instructions. We will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to vote our preferred stock in accordance with these instructions. The depositary will not vote our preferred stock to the extent that it does not receive specific instructions from the holders of depositary receipts.

#### Withdrawal of Preferred Stock

Owners of depositary shares will be entitled to receive upon surrender of depositary receipts at the principal office of the depositary and payment of any unpaid amount due to the depositary, the number of whole shares of our preferred stock underlying their depositary shares.

------

[*Table of Contents*](#TABLEOFCONTENTS)

Partial shares of our preferred stock will not be issued. Holders of our preferred stock will not be entitled to deposit the shares under the deposit agreement or to receive depositary receipts evidencing depositary shares for our preferred stock.

#### Amendment and Termination of the Deposit Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between the depositary and us as set forth in the deposit agreement. In certain instances described in the deposit agreement, holders of the outstanding depositary shares will be required to approve an amendment to the deposit agreement. The deposit agreement may be terminated by the depositary or us only if certain specific conditions set forth in the deposit agreement are met.

#### Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangement. We will also pay charges of the depositary in connection with:

<br> • the initial deposit of our preferred stock;

<br> • the initial issuance of the depositary shares;

<br> • any redemption of our preferred stock; and

<br> • all withdrawals of our preferred stock by owners of depositary shares.

Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and other specified charges as provided in the deposit agreement for their accounts. If these charges have not been paid, the depositary may:

<br> • refuse to transfer depositary shares;

<br> • withhold dividends and distributions; and

<br> • sell the depositary shares evidenced by the depositary receipt.

#### Miscellaneous

The depositary will forward to the holders of depositary receipts all reports and communications we deliver to the depositary that we are required to furnish to the holders of our preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of our preferred stock.

Neither we nor the depositary will be liable if either we or the depositary are prevented or delayed by law or any circumstance beyond the control of either the depositary or us in performing our respective obligations under the deposit agreement. Our obligations and the depositary's obligations will be limited to the performance in good faith of our or the depositary's respective duties under the deposit agreement. Neither we nor the depositary will be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or our preferred stock unless satisfactory indemnity is furnished. The depositary and we may rely on:

<br> • written advice of counsel or accountants;

<br> • information provided by holders of depositary receipts or other persons believed in good faith to be competent to give such information; and

<br> • documents believed to be genuine and to have been signed or presented by the proper party or parties.

#### Resignation and Removal of Depositary

The depositary may resign at any time by delivering a notice to us. We may remove the depositary at any time. Any such resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of such appointment. As set forth in the deposit agreement, the successor depositary must be appointed within a certain time frame after delivery of the notice for resignation or removal and must meet certain organizational and asset tests.

#### DESCRIPTION OF DEBT SECURITIES

*The complete terms of the debt securities will be contained in the indenture and indenture supplement applicable to the debt securities. These documents have been or will be included or incorporated by reference as exhibits to the registration statement of which this prospectus is a part. You should read the indenture and indenture supplement. You should also read the prospectus supplement, which will contain additional information and which may update or change some of the information below.*

#### General

We may issue debt securities from time to time in one or more series. Unless otherwise stated in the applicable prospectus supplement, we will not be limited in the amount of debt securities that we may issue, and neither the senior debt securities nor the subordinated debt securities will be secured by any of our property or assets. Thus, by owning debt securities, you are one of our unsecured creditors, unless otherwise provided in a supplemental indenture.

We are a holding company and conduct substantially all of our operations through subsidiaries. As a result, claims of holders of debt securities will generally have a junior position to claims of creditors of our subsidiaries (including, without limitation, Orrstown Bank), except to the extent that we may be recognized as a creditor of those subsidiaries. In addition, our right to participate as a stockholder in any distribution of assets of any subsidiary (and thus the ability of holders of debt securities to benefit from such distribution as our creditors) is junior to creditors of each subsidiary, including depositors of Orrstown Bank.

We may issue senior debt securities or subordinated debt securities under one indenture, which may be supplemented or amended from time to time. Indentures will be subject to and governed by the Trust Indenture Act of 1939, as amended, and may be supplemented or amended from time to time following its execution and will be filed as an exhibit to the registration statement of which this prospectus forms a part or incorporated therein by reference.

The indenture will contain the full legal text of the matters described in this section of the prospectus. Because this section is a summary, it does not describe every aspect of the debt securities or any applicable indentures. This summary is therefore subject to and is qualified in its entirety by reference to all the provisions of the indenture, including any definitions of terms used in such indenture. Your rights will be defined by the terms of the indenture, not the summary provided herein. This summary is also subject to and qualified by reference to the description of the particular terms of a particular series of debt securities described in the applicable prospectus supplement or supplements, and any supplemental indenture entered into in connection with that series of debt securities.

The debt securities may be denominated and payable in U.S. dollars. We may also issue debt securities, from time to time, with the principal amount, interest or other amounts payable on any relevant payment date to be determined by reference to one or more currency exchange rates, securities or baskets of securities, commodity prices, indices or any other financial, economic or other measure or instrument, including the occurrence or non-occurrence of any event or circumstance. All references in this prospectus or any prospectus supplement to other amounts will include premiums, if any, other cash amounts payable under the applicable indenture, and the delivery of securities or baskets of securities under the terms of the debt securities. Debt securities may bear interest at a fixed rate, which may be zero, or a floating rate.

Some of the debt securities may be issued as original issue discount debt securities. Original issue discount securities bear no interest or bear interest at below market rates and will be sold at a discount below their stated principal amount. A prospectus supplement relating to an issue of original issue discount securities will contain information relating to United States federal income tax, accounting, and other special considerations applicable to original issue discount securities.

------

[*Table of Contents*](#TABLEOFCONTENTS)

We will set forth in the applicable prospectus supplement the terms, if any, on which a series of debt securities may be convertible into or exchangeable for our preferred stock, common stock or other securities. We will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our preferred stock, common stock or other securities that holders of the series of debt securities receive would be subject to adjustment.

We will generally have no obligation to repurchase, redeem, or change the terms of debt securities upon any event (including a merger, consolidation, change in control or disposition of substantially all of our assets) that might have an adverse effect on our credit quality.

#### Terms of Debt Securities to be Included in the Prospectus Supplement

• the currency or currencies in which the debt securities may be purchased, are denominated and are payable, which may be a foreign currency or units of two or more foreign currencies or a composite currency or currencies, and the related terms and conditions, including whether we or the holders of any such debt securities may elect to receive payments in respect of such debt securities in a currency or currency unit other than that in which such debt securities are stated to be payable;

• whether the amount of payments of principal of and premium, if any, or interest, if any, on the debt securities may be determined with reference to an index, formula or other method, which index, formula or method may, but need not be, based on a currency, currencies, currency unit or units or composite currency or currencies or with reference to changes in prices of particular securities or commodities, and the manner in which the amounts are to be determined;

<br> • any additions to, modifications of or deletions from the terms of the debt securities with respect to events of default, amendments, merger, consolidation and sale or covenants set forth in the applicable indenture;

• if the debt securities will be issuable only in global form, the depository or its nominee with respect to the debt securities and the circumstances under which the global security may be registered for transfer or exchange in the name of a person other than the depository or its nominee;

<br> • the applicability, if any, of the defeasance and covenant defeasance provisions of the indenture and any additional or different terms on which the series of debt securities may be defeased;

<br> • any trustee, depositary, authenticating agent, paying agent, transfer agent, registrar or other agent with respect to the debt securities; and

<br> • any other terms of the debt securities.

**Consolidation, Merger or Sale**

The indenture in the form initially filed as an exhibit to the registration statement of which this prospectus is a part does not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of all or substantially all of our assets, except that any successor of ours or acquiror of such assets must be a corporation, partnership, trust or limited liability company organized and existing under the laws of the United States, any state thereof, or the District of Columbia, and must assume all of our obligations under the indenture and the debt securities, as appropriate. In addition, the terms of any debt securities that we may offer pursuant to this prospectus may limit our ability to merge or consolidate or otherwise sell, convey, transfer or otherwise dispose of all or substantially all of our assets, which terms would be set forth in the applicable prospectus supplement and supplemental indenture.

#### Events of Default Under the Indenture

*Senior Debt Securities*

The events of default under the indenture, subject to modification or deletion as provided in a supplemental indenture with respect to any specific series of senior debt securities, include the following events:

------

[*Table of Contents*](#TABLEOFCONTENTS)

<br> • if we fail to pay interest when due and payable and our failure continues for 30 days and the time for payment has not been extended or deferred;

<br> • if we fail to pay the principal, premium or sinking fund payment, if any, when due and payable and the time for payment has not been extended or deferred;

• if we fail to observe or perform any other covenant contained in the debt securities or the indenture, other than a covenant specifically relating to another series of debt securities, and our failure continues for 90 days after we (and the indenture trustee in the event of notice from security holders) receive notice from the indenture trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and

<br> • if specified events of bankruptcy, insolvency or reorganization occur with respect to the Company or the Bank

*Subordinated Debt Securities*

The events of default under the indenture, subject to modification or deletion as provided in a supplemental indenture with respect to any specific series of subordinated debt securities, include specified events of bankruptcy, insolvency or reorganization involving the Company or the Bank.

*Acceleration of Maturity; Rescission and Annulment*

Unless otherwise indicated in the applicable prospectus supplement, if an event of default with respect to debt securities of any series occurs and is continuing, the indenture trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the indenture trustee if notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately; provided, however, that if an event of default with respect to senior debt securities occurs by reason of bankruptcy, insolvency or reorganization involving the Company or the Bank, the entire unpaid principal of, and accrued interest, if any, shall become immediately due and payable without any notice to us.

At any time after a declaration of acceleration with respect to any series of debt securities has been made, and before a judgment or decree for payment of the money due has been obtained by the indenture trustee, the holders of a majority in aggregate principal amount of the outstanding debt securities of that series may rescind and annul such declaration and its consequences if we have paid or deposited with the indenture trustee a sum sufficient to pay:

<br> • the principal of, premium, if any, and all interest (including overdue interest) on all debt securities of that series that have become due other than by such declaration of acceleration; and

• all sums paid or advanced by the indenture trustee under the indenture and the reasonable compensation, expenses, disbursements and advances of the indenture trustee, its agents and counsel, except as a result of negligence or willful misconduct of the indenture trustee as determined by a court of competent jurisdiction in a final, non-appealable order;

and all events of default or defaults with respect to the debt securities of such series, other than the nonpayment of the principal of, or any premium and interest on, securities of such series which have become due solely by such declaration of acceleration, have been cured or waived.

*Waiver of Event of Default*

The holders of a majority in aggregate principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to such series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, or defaults in respect of a covenant or provision which cannot be modified or amended under the indenture without the consent of the holder of each outstanding debt security of the series affected. Any waiver would cure the default or event of default.

------

[*Table of Contents*](#TABLEOFCONTENTS)

*Limitations on Enforcement of Remedies*

Subject to the terms of the indenture, if an event of default under the indenture occurs and continues, the indenture trustee would be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the indenture trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the indenture trustee, or exercising any trust or power conferred on the indenture trustee, with respect to the debt securities of that series, provided that:

<br> • the direction so given by the holder is not in conflict with any law or the indenture; and

<br> • subject to its duties under the Trust Indenture Act of 1939, the indenture trustee need not take any action that might involve it in personal liability or might be unduly prejudicial to the holders not involved in the proceeding.

A holder of the debt securities of any series will have the right to institute a proceeding under the indenture or to appoint a receiver or trustee, or to seek other remedies only if:

<br> • the holder has given written notice to the indenture trustee of a continuing event of default with respect to that series;

• the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request to the indenture trustee, and such holders have offered reasonable indemnity to the indenture trustee to institute the proceeding as trustee; and

• for 60 days after receipt of written notice of such event of default, request to institute the proceeding and offer of indemnity, the indenture trustee does not institute such proceeding, and does not receive from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series other conflicting directions.

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities on the applicable stated maturity date.

We will periodically file statements with the indenture trustee regarding our compliance with specified covenants in the indenture.

#### Modification of Indenture; Waiver

By entering into supplemental indentures, we and the indenture trustee may modify the terms of the indenture without the consent of any holders with respect to specific matters, including:

<br> • to evidence the assumption by a successor corporation of our obligations in compliance with the provisions described above under "Consolidation, Merger or Sale";

• to add to our covenants for the benefit of the holders of all or any series of debt securities or to surrender any right or power herein conferred upon us; provided that such action shall not adversely affect the interests of the holders of the debt securities of any series then outstanding;

<br> • to add to or change any of the provisions of the indenture to such extent as shall be necessary to permit or facilitate the issuance of debt securities in uncertificated or global form;

• to establish any series of debt securities and the form or terms of securities of any series, including, without limitation, but solely insofar as it relates to subordinated securities, any subordination provisions and any deletions from or additions or changes to the indenture in connection therewith;

<br> • to evidence and provide for the acceptance of appointment by a successor trustee;

<br> • to fix any ambiguity, defect or inconsistency in the indenture;

------

[*Table of Contents*](#TABLEOFCONTENTS)

• to amend, supplement, add or eliminate any provision contained in the indenture or in any supplemental indenture or in any debt securities, provided that such amendment, supplement, addition or elimination does not apply to any outstanding debt security issued prior to the date of such supplemental indenture and entitled to the benefits of such provision;

<br> • to add any additional events of default; or

<br> • to add, change or eliminate any provision of the indenture as shall be necessary or desirable in accordance with any amendments to the Trust Indenture Act of 1939, as amended.

In addition, under the indenture or supplemental indentures, the rights of holders of a series of debt securities may be changed by us and the indenture trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, we and the indenture trustee may make the following changes only with the consent of each holder of any outstanding debt securities affected:

<br> • extending the fixed maturity of the series of debt securities;

• reducing the principal amount of, reducing the rate of or extending the time of payment of interest on, or reducing any premium payable upon the redemption of, any debt securities;

<br> • change any redemption, repurchase, conversion or exchange provisions applicable to any outstanding debt security in any manner that is adverse to the holders thereof;

• reducing the percentage in principal amount of debt securities of any series the consent of whose holders are required for any supplemental indenture; or

<br> • modifying any of the four bullet points above.

#### Discharge, Defeasance and Covenant Defeasance

We may elect to have our obligations under the indenture discharged with respect to the outstanding debt securities of any series, known as defeasance. Defeasance means that we will be deemed to have paid and discharged the entire indebtedness represented by the outstanding debt securities of such series under the indenture, except for:

<br> • the rights of holders of the debt securities to receive principal, interest and any premium when due;

• our obligations with respect to the debt securities concerning issuing temporary debt securities, registration of transfer of debt securities, mutilated, destroyed, lost or stolen debt securities and the maintenance of an office or agency for payment for security payments held in trust;

<br> • the rights, powers, trusts, duties and immunities of the trustee; and

<br> • the defeasance provisions of the indenture.

In addition, we may elect to have our obligations released with respect to certain covenants applicable to any series of outstanding debt securities established by and set forth in a supplemental indenture, known as covenant defeasance. If we so elect, any failure to comply with such obligations will not constitute a default or an event of default with respect to the debt securities of such series.

In order to exercise either defeasance or covenant defeasance with respect to outstanding debt securities of any series:

• we must irrevocably have deposited or caused to be deposited with the indenture trustee as trust funds for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to the benefit of, the holders of the debt securities of such series:

<br> o money; or

------

[*Table of Contents*](#TABLEOFCONTENTS)

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;o | U.S. government obligations (or equivalent government obligations in the case of debt securities denominated in other than U.S. dollars or a specified currency) that will provide, not later than one day before the due date of any payment, money in an amount; or |

---

<br> o a combination of money and U.S. government obligations (or equivalent government obligations, as applicable);

in each case sufficient, in the written opinion of a nationally recognized firm of independent public accountants to pay and discharge, and which shall be applied by the trustee to pay and discharge, all of the principal (including mandatory sinking fund payments), interest and any premium at due date or maturity;

• in the case of defeasance, we have delivered to the indenture trustee an opinion of counsel stating that, under then applicable Federal income tax law, the holders of the debt securities of that series will not recognize income, gain or loss for Federal income tax purposes as a result of the defeasance to be effected and will be subject to the same Federal income tax as would be the case if the defeasance did not occur;

• in the case of covenant defeasance, we have delivered to the indenture trustee an opinion of counsel to the effect that the holders of the debt securities of that series will not recognize income, gain or loss for Federal income tax purposes as a result of the covenant defeasance to be effected and will be subject to the same Federal income tax as would be the case if the covenant defeasance did not occur;

<br> • no event of default or default with respect to the outstanding debt securities of that series has occurred and is continuing at the time of such deposit, or any time during the period ending on the 90<sup>th</sup> day after the date of such deposit;

<br> • the defeasance or covenant defeasance will not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which we are a party;

<br> • the defeasance or covenant defeasance will not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act of 1940, as amended, unless the trust is registered under such Act;

• if the debt securities are to be redeemed prior to the maturity date (other than from mandatory sinking fund payments or analogous payments), notice of such redemption shall have been duly given pursuant to the indenture or provision therefore satisfactory to the trustee shall have been made; and

<br> • we have delivered to the trustee an officer's certificate and an opinion of counsel stating that all conditions precedent with respect to the defeasance or covenant defeasance have been satisfied.

#### Form, Exchange and Transfer

We will issue the debt securities of each series in registered form without coupons and, unless we otherwise specify in the applicable prospectus supplement or free writing prospectus, in denominations of $1,000 and any integral multiple of $1,000. The indenture provides that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, a depositary named by us and identified in a prospectus supplement or free writing prospectus with respect to that series.

At the option of the holder, subject to the terms of the indenture and the limitations applicable to global securities described in the applicable prospectus supplement or free writing prospectus, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the indenture and the limitations applicable to global securities set forth in the applicable prospectus supplement or free writing prospectus, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will make no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

------

[*Table of Contents*](#TABLEOFCONTENTS)

We will name in the applicable prospectus supplement or free writing prospectus the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If we elect to redeem the debt securities of any series, we will not be required to:

• issue, register the transfer or exchange of any debt securities of any series being redeemed in part during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any debt securities that may be selected for redemption and ending at the close of business on the day of the mailing; or

<br> • register the transfer of or exchange any debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any debt securities we are redeeming in part.

#### Information Concerning the Indenture Trustee

The indenture trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the indenture trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs.

#### Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement or free writing prospectus, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that, unless we otherwise indicate in the applicable prospectus supplement or free writing prospectus, we may make interest payments by check which we will mail to the holder. We will name in the applicable prospectus supplement or free writing prospectus any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the indenture trustee for the payment of the principal of or any premium or interest on any debt securities which remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

#### Governing Law

Unless otherwise provided in the applicable prospectus supplement, the indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act of 1939 is applicable.

------

[*Table of Contents*](#TABLEOFCONTENTS)

Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security.

The following are some of the unit terms that could be described in a prospectus supplement:

<br> • title of the units;

<br> • aggregate number of units;

<br> • price or prices at which the units will be issued;

<br> • designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

<br> • information with respect to book-entry procedures;

<br> • other material terms, including terms relating to transferability, exchange, exercise or amendments of the units.

The provisions described in this section, as well as those described under "Description of Common Stock," "Description of Preferred Stock," "Description of Debt Securities" and "Description of Warrants" will apply to each unit and to any common stock, preferred stock, debt security or warrant included in each unit, respectively.

Unless otherwise provided in the applicable prospectus supplement, the unit agreements will be governed by the laws of the Commonwealth of Pennsylvania. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date. We will file as an exhibit to a filing with the SEC that is incorporated by reference into this prospectus the forms of the unit agreements containing the terms of the units being offered. The description of units in any prospectus supplement will not necessarily describe all of the terms of the units in detail. You should read the applicable unit agreements for a complete description of all of the terms.

#### PLAN OF DISTRIBUTION

We may sell the securities from time to time pursuant to public offerings, negotiated transactions, block trades or a combination of these methods. We may sell the securities to or through an underwriter or group of underwriters managed or co-managed by one or more underwriters, or to or through dealers, through agents, directly to one or more investors or through a combination of such methods of sale.

We may distribute securities from time to time in one or more transactions:

<br> • at a fixed price or prices which may be changed;

<br> • at market prices prevailing at the time of sale;

<br> • at prices related to such prevailing market prices; or

<br> • at negotiated prices.

Each time we sell securities a prospectus supplement will describe the method of distribution of the securities and any applicable restrictions.

------

[*Table of Contents*](#TABLEOFCONTENTS)

The prospectus supplement or supplements will describe the terms of the offering of the securities, including:

<br> • the name or names of the underwriters, placement agents or dealers, if any;

<br> • the purchase price of the securities and the proceeds we will receive from the sale;

<br> • any over-allotment options under which underwriters may purchase additional securities from us;

<br> • any agency fees or underwriting discounts and other items constituting agents' or underwriters' compensation;

<br> • any discounts or concessions allowed or reallowed to be paid to dealers (which may be changed at any time); and

<br> • any securities exchange or market on which the securities may be listed or quoted.

Unless stated otherwise in the applicable prospectus supplement, the obligations of any underwriters to purchase securities will be subject to certain conditions set forth in the applicable underwriting agreement, and generally the underwriters will be obligated to purchase all of the securities if they purchase any of the securities. If underwriters are used in the sale of any securities, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions described above. The securities may be either offered to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters. Generally, the underwriters' obligations to purchase the securities will be subject to certain conditions precedent. If a dealer is used in a sale, we may sell the securities to the dealer as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

We or our agents may solicit offers to purchase securities from time to time. Unless stated otherwise in the applicable prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment.

In connection with the sale of securities, underwriters or agents may receive compensation (in the form of fees, discounts, concessions or commissions) from us or from purchasers of securities for whom they may act as agents. Underwriters may sell securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of securities may be deemed to be "underwriters," as that term is defined in the Securities Act, and any discounts or commissions received by them from us and any profits on the resale of the securities by them may be deemed to be underwriting discounts and commissions under the Securities Act. We will identify any such underwriter or agent, and we will describe any compensation paid to them, in the related prospectus supplement.

Underwriters, dealers and agents may be entitled under agreements with us to indemnification against and contribution toward certain civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the underwriters, dealers or agents may make with respect to these liabilities.

If stated in the applicable prospectus supplement, we may authorize underwriters, dealers or agents to solicit offers by certain investors to purchase securities from us at the public offering price set forth in the prospectus supplement under delayed delivery contracts providing for payment and delivery on a specified date in the future. These contracts will be subject only to those conditions set forth in the applicable prospectus supplement and the applicable prospectus supplement will set forth the commission payable for solicitation of these contracts.

The securities we may offer, other than common stock, will be new issues of securities with no established trading market. No assurance can be given as to the liquidity of the trading market for any of our securities. Any underwriter may make a market in these securities; however, no underwriter will be obligated to do so, and any underwriter may discontinue any market making at any time, without prior notice.

------

[*Table of Contents*](#TABLEOFCONTENTS)

Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum price. Syndicate-covering or other short-covering transactions involve purchases of the securities, either through exercise of the over-allotment option or in the open market after the distribution is completed, to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

Any underwriters who are qualified market makers on Nasdaq (or any exchange or quotation system on which our securities are listed) may engage in passive market making transactions in our common stock, preferred stock, depositary shares, debt securities, warrants and purchase contracts, as applicable, on Nasdaq in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the securities. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker's bid, however, the passive market maker's bid must then be lowered when certain purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

Certain of the underwriters or agents and their associates may engage in transactions with and perform services for us or our affiliates in the ordinary course of their respective businesses.

#### LEGAL MATTERS
Unless otherwise indicated in the applicable prospectus supplement, the validity of the securities offered hereby will be passed upon for us by Pillar Aught LLC, Harrisburg, Pennsylvania. If the validity of the securities offered hereby in connection with offerings made pursuant to this prospectus are passed upon by counsel for underwriters, dealers or agents, if any, such counsel will be named in the prospectus supplement related to such offering.

| **Item 15.** | **Indemnification of Directors and Officers.** |

---

The following is only a general summary of certain aspects of Pennsylvania law and the Company's articles of incorporation and bylaws related to the indemnification of directors and officers, and does not purport to be complete. It is qualified in its entirety by reference to the detailed provisions of Sections 1741-1750 of the Pennsylvania Business Corporation Law of 1988, as amended, or PBCL.

Sections 1741-1743 of the PBCL provide that a business corporation may indemnify directors and officers against liabilities they may incur in such capacities provided certain standards are met, including good faith and the belief that the particular action is in the best interests of the corporation. In general, this power to indemnify does not exist in the case of actions against a director or officer by or in the right of the corporation if the person entitled to indemnification shall have been adjudged to be liable to the corporation unless and only to the extent a court determines that the person is fairly and reasonably entitled to indemnification. A corporation is required to indemnify directors and officers against expenses they may incur in defending actions against them in such capacities if they are successful on the merits or otherwise in the defense of such actions. Section 1746 of the PBCL provides that the foregoing provisions shall not be deemed exclusive of any other rights to which a person seeking indemnification may be entitled under, among other things, any by-law provision, provided that no indemnification may be made in any case where the act or failure or act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness. Section 1747 of the PBCL authorizes a corporation to purchase insurance for directors and other representatives. The foregoing statement is subject to the detailed provisions of Section 1741-1750 of the PBCL.

The Company's bylaws provide for indemnification of directors and officers to the extent provided in the PBCL. In accordance with Section 1713 of the PBCL, the bylaws also include a provision that the Company's directors shall not be personally liable for monetary damages such for any action taken, or failure to take any action, unless: (1) the director has breached or failed to perform the duties of his office in good faith, in a manner he reasonably believes to be in the best interests of the company and with such care, including reasonably inquiry, skill and diligence, as a person of ordinary prudence would use under similar circumstances; and (2) the breach or failure to perform constitute self-dealing, willful misconduct or recklessness. Pursuant to Section 1713 of the PBCL, this limitation of personal liability does not apply to (i) the responsibility or liability of a director pursuant to any criminal statute or (ii) the liability of a director for the payment of taxes pursuant to federal state or local law.

------

[*Table of Contents*](#TABLEOFCONTENTS)

Further, the Company may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the Company or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity or arising out of his status as such, whether or not the Company would have the power to indemnify him against such liability under the provisions of the articles of incorporation.

Any underwriting agreement that the Company might enter into (Exhibit 1.1) will provide for indemnification by any underwriters of the Company, the Company's directors, the Company's officers who sign the registration statement and the Company's controlling persons for some liabilities, including liabilities arising under the Securities Act.

**Item 17.** **Undertakings.**<br>

The undersigned Registrant hereby undertakes:

<br> (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

<br> (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

<br> (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

*Provided, however*, that paragraphs (1)(i), (1)(ii) and (1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

<sup>(2)</sup> That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment 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.<br>

<br> (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

<br> (4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

------

[*Table of Contents*](#TABLEOFCONTENTS)

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof. *Provided, however*, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

<br> (5) That, for the purpose of determining liability of the Registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

<br> (i) Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

<br> (ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant;

<br> (iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned Registrant; and

<br> (iv) Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

<sup>(6)</sup> That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this 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.<br>

------

[*Table of Contents*](#TABLEOFCONTENTS)

<sup>(7)</sup> To file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under section 305(b)(2) of the Trust Indenture Act.<br>

<sup>(8)</sup> That, for the purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b) (1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.<br>

<sup>(9)</sup> That, for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus 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.<br>

**The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to 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.**

**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 foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 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 Securities Act of 1933 and will be governed by the final adjudication of such issue.**

#### Re: Orrstown Financial Services, Inc.
Orrstown Financial Services, Inc.

4750 Lindle Road

Harrisburg, PA 17111

Ladies and Gentlemen:

We have acted as counsel to Orrstown Financial Services, Inc., a Pennsylvania corporation (the "<u>Company</u>"), in connection with its filing of a shelf registration statement on Form S-3 (the "<u>Registration Statement</u>"), including the prospectus constituting a part thereof (the "<u>Prospectus</u>"), to be filed with the Securities and Exchange Commission (the "<u>Commission</u>") under the Securities Act of 1933, as amended (the "<u>Securities Act</u>"). We have been requested by the Company to render this opinion in connection with the filing of the Registration Statement.

The Prospectus provides that it will be supplemented in the future by one or more supplements to the Prospectus (each a "<u>Prospectus Supplement</u>"). The Prospectus, as supplemented by various Prospectus Supplements, will provide for the registration by the Company of up to Two Hundred Million ($200,000,000) aggregate offering price of: (i) shares of common stock, no par value (the "<u>Common Stock</u>"); (ii) shares of preferred stock, par value $1.25 per share, in one or more series or classes (the "<u>Preferred Stock</u>"); (iii) depositary shares representing a fraction of a share of the applicable series or class of Preferred Stock (the "<u>Depositary Shares</u>"); (iv) secured or unsecured debt securities, in one or more series, which may be either senior debt securities, senior subordinated debt securities, subordinated debt securities or junior subordinated securities (the "<u>Debt Securities</u>") to be issued pursuant to one or more Indentures between the Company and a trustee or bank to be named (the "<u>Trustee</u>"), which may be supplemented for any series of Debt Securities (the "<u>Indenture</u>"); (v) warrants to purchase Common Stock, Preferred Stock or Debt Securities (the "<u>Warrants</u>"); (vi) contracts for the purchase or sale of Common Stock, Preferred Stock, Depositary Shares or Debt Securities ("<u>Purchase Contracts</u>"); or (vii) units composed of one or more of the foregoing (the "<u>Units</u>"). The Common Stock, Preferred Stock, Depositary Shares, Debt Securities, Warrants, Purchase Contracts and Units are collectively referred to herein as the "<u>Securities</u>". Any Debt Securities may be exchangeable and/or convertible into shares of Common Stock or Preferred Stock. The Preferred Stock may also be exchangeable for and/or convertible into shares of Common Stock or another series of Preferred Stock. The Units may be exchangeable and/or settled into the Securities comprising the Units.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In rendering our opinion, we have reviewed the Registration Statement and the exhibits thereto. We have also reviewed such corporate documents and records of the Company, such certificates of public officials and such other matters as we have deemed necessary or appropriate for purposes of this opinion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Except to the extent we opine as to the binding effect of certain documents as set forth in paragraphs 3, 4, 5, 6 and 7 below, we have assumed that all documents referenced below are the valid and binding obligations of and enforceable against the parties thereto. We have also assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the conformity to authentic original documents of all documents submitted to us as certified, conformed or photostatic copies and the legal capacities of all natural persons.

(a) When the Debt Securities have been duly established in accordance with the Indenture (including, without limitation, the adoption by the Board of Directors of the Company of a resolution duly authorizing the issuance and delivery of the Debt Securities), duly authenticated by the Trustee and duly executed and delivered on behalf of the Company against payment therefor in accordance with the terms and provisions of such Indenture and as contemplated by the Registration Statement, the Prospectus and the related Prospectus Supplement(s), (b) when the Registration Statement and any required post-effective amendment thereto and any and all Prospectus Supplement(s) required by applicable laws have all become effective under the Securities Act, (c) assuming that the terms of the Debt Securities as executed and delivered are as described in the Registration Statement, the Prospectus and the related Prospectus Supplement(s), (d) assuming that the Debt Securities as executed and delivered do not violate any law applicable to the Company or result in a default under or breach of any agreement or instrument binding upon the Company, (e) assuming that the Debt Securities as executed and delivered comply with all requirements and restrictions, if any, applicable to the Company, whether imposed by any court or governmental or regulatory body having jurisdiction over the Company, and (f) assuming that the Debt Securities are then issued and sold as contemplated in the Registration Statement, the Prospectus and the related Prospectus Supplement(s), then the Debt Securities (including any Debt Securities issued in exchange or in settlement of Units that are exchangeable or settled into Debt Securities) will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with the terms of the Debt Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. (a) When a warrant agreement relating to the Warrants has been duly authorized (the "<u>Warrant Agreement</u>"), executed and delivered and the Warrants and the securities of the Company for which the Warrants will be exercisable have been duly authorized by the Company's Board of Directors, (b) assuming that the terms of the Warrants and of their issuance and sale have been duly established in conformity with the Articles and Bylaws and the Warrant Agreement, (c) assuming that the Registration Statement and any required post-effective amendment thereto and any and all Prospectus Supplement(s) required by applicable laws have all become effective under the Securities Act, (d) assuming that the terms of the Warrants as executed and delivered are as described in the Registration Statement, the Prospectus and the related Prospectus Supplement(s), (e) assuming that the Warrants, as executed and delivered, do not violate any law applicable to the Company or result in a default under or breach of any agreement or instrument binding upon the Company, (f) assuming that the Warrants as executed and delivered comply with all requirements and restrictions, if any, applicable to the Company, whether imposed by any court or governmental or regulatory body having jurisdiction over the Company, and (g) assuming that the Warrants are then issued and sold as contemplated in the Registration Statement, the Prospectus and the Prospectus Supplement(s), then upon issuance of and delivery of and payment for such Warrants in the manner contemplated by the Registration Statement, the Prospectus and the related Prospectus Supplement and the Warrant Agreement and by such resolution, the Warrants (including any Warrants issued upon the exchange or settlement of Units that are exchangeable or able to be settled for Warrants) will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, and the Warrants will be validly issued.

The opinions set forth in paragraphs 3, 4, 5, 6 and 7 above are subject to the following exceptions, limitations and qualifications: (i) the effect of bankruptcy, insolvency, reorganization, arrangement, moratorium, fraudulent conveyance, fraudulent transfer and other similar laws relating to or affecting the rights of creditors; (ii) the effect of general principles of equity (including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance, injunctive relief and other equitable remedies), regardless of whether considered in a proceeding at law or in equity; (iii) the effect of public policy considerations that may limit the rights of the parties to obtain further remedies; (iv) we express no opinion with respect to the enforceability of provisions relating to choice of law, choice of venue, jurisdiction or waivers of jury trial; and (v) we express no opinion with respect to the enforceability of any waiver of any usury defense.

------

Our opinion is rendered as of the date hereof, and we assume no obligation to advise you of changes in law or fact (or the effect thereof on the opinions expressed herein) that hereafter may come to our attention. This opinion is to be used only in connection with the offer and sale of the Securities while the Registration Statement is in effect.

Our opinion is limited to the federal laws of the United States, the laws of the Commonwealth of Pennsylvania and the laws of the State of New York that, in our experience, are normally applicable to transactions of the type contemplated by the Registration Statement. We express no opinion as to the effect of the law of any other jurisdiction. Our opinion is rendered as of the date hereof, and we assume no obligation to advise you of changes in law or fact (or the effect thereof on the opinions expressed herein) that hereafter may come to our attention.
