An investment in shares of Senior Common Stock involves substantial risks. You should purchase our securities

only if you can afford a complete loss of your investment. Please read and consider the risk factors in

the prospectus supplement and prospectus before purchasing any securities. The most significant risk factors

include the following:

Risks Relating to Our Senior Common Stock and this Offering:

• There is no established public trading market for shares of Senior Common Stock, and we have no plans

to list these shares on a national securities exchange.

• We established the offering price of shares of Senior Common Stock on an arbitrary basis, and, as a

result, the actual value of your investment may be substantially less than what you pay.

• The calculation of the Exchange Ratio could result in a deterrent to your exchanging shares of Senior

Common Stock for shares of Listed Common Stock if shares of Listed Common Stock are trading at lower

levels at the time that you desire to exchange your shares.

• Your ability to redeem shares of Senior Common Stock pursuant to our share redemption program is limited

to the proceeds generated by our distribution reinvestment plan, and the share redemption program

may be amended, suspended or terminated by our Board at any time without stockholder approval.

• If you do not agree with the decisions of our Board, then you will not be able to influence changes in our policies

and operations because holders of shares of Senior Common Stock will generally have no voting rights.

• Our charter contains restrictions on the ownership and transfer of shares of our capital stock, and these

restrictions may inhibit your ability to sell your shares of Senior Common Stock promptly, or at all.

• Our Dealer Manager is one of our affiliates, and, therefore, an investor in shares of Senior Common Stock

would not have the benefit of an independent underwriter who has performed an independent due diligence

review.

• Highly leveraged tenants and borrowers may be unable to pay rent or make mortgage payments, which

could adversely affect our cash available to make distributions to holders of our Senior Common Stock.

Risks Relating to Our Company and Our Operations:

• Our business strategy relies heavily on external financing, which may expose us to risks associated with

leverage such as restrictions on additional borrowing and payment of distributions to stockholders, risks

associated with balloon payments, and risk of loss of our equity upon foreclosure.

• We are subject to certain risks associated with real estate ownership and lending which could reduce the

value of our investments, including but not limited to, changes in the general economic climate; changes

in local conditions such as an oversupply of space or reduction in demand for real estate; changes in

interest rates and the availability of financing; competition from other available space; and changes in

laws and governmental regulations, including those governing real estate usage, zoning and taxes.

• Our properties may be subject to impairment charges, which could adversely affect our results of operations

and FFO.

• Illiquidity of real estate investments may make it difficult for us to sell properties in response to market

conditions and our properties may include special use and single or multi-tenant properties that may be

difficult to sell or re-lease upon tenant defaults or early lease terminations which could harm our financial

condition and ability to make distributions.

• Our real estate investments have a limited number of tenants, many of which are small- and medium-sized

businesses, and are concentrated in a limited number of industries, which subjects us to an increased risk

of significant loss if any one of these tenants is unable to pay or if particular industries experience

downturns.

• We may be unable to renew leases, lease vacant space or re-lease space as leases expire, which could

adversely affect our business and our ability to make distributions to our stockholders.

• We may enter into sale-leaseback transactions, whereby we would purchase a property and then lease the

same property back to the person from whom we purchased it. If a sale-leaseback transaction is

re-characterized in a tenant’s bankruptcy proceeding, our financial condition could be adversely affected.

• We are dependent upon our key management personnel, who are employed by our Adviser, for our future

success. The departure of any of our executive officers or key employees could have a material adverse

effect on our ability to implement our business strategy and to achieve our investment objectives.

• Our success depends on the performance of our Adviser and if our Adviser makes inadvisable investment

or management decisions, our operations could be materially adversely impacted.

• We may have conflicts of interest with our Adviser and other affiliates, including but not limited to the following

conflicts: (i) our Adviser may realize substantial compensation on account of its activities on our

behalf, and may, therefore, be motivated to approve acquisitions solely on the basis of increasing compensation

to itself; (ii) we may experience competition with our affiliates for financing transactions; (iii) our

Adviser may earn fee income from our borrowers or tenants; and (iv) our Adviser and other affiliates could

compete for the time and services of our officers and directors.

• If we fail to qualify as a REIT, our operations and dividends to stockholders would be adversely impacted.

• To the extent that our distributions represent a return of capital for tax purposes, you could recognize an

increased capital gain upon a subsequent sale of your stock.

OUR COMPANY

Gladstone Commercial Corporation (our Company) was incorporated under

the Maryland General Corporation Law on February 14, 2003 primarily for

the purpose of investing in and owning net leased industrial and commercial

real estate property and selectively making long-term industrial and

commercial loans to creditworthy entities. We are a publicly-traded real

estate investment trust, or REIT. Our Listed Common Stock is traded on

the NASDAQ Global Select Market under the trading symbol “GOOD.”

We lease our real estate to a wide cross section of tenants ranging from

small businesses to large public companies, many of which do not have

publicly-rated debt. We have in the past entered into, and intend in the

future to enter into, purchase agreements for real estate that have triple

net leases with terms of 10 to 15 years and built in rental increases. Under

a triple net lease, the tenant is required to pay all operating, maintenance,

insurance costs and real estate taxes with respect to the leased property.

We actively communicate with buyout funds, real estate brokers and other

third parties to locate properties for potential acquisition or mortgage

financing in an effort to build our portfolio. As of February 19, 2013, we

owned 80 properties located in 24 states that contain approximately 8.0

million rentable square feet.

Our executive offices are located at 1521 Westbranch Drive, Suite 200,

McLean, Virginia 22102, and our telephone number is (703) 287-5800.
