WE HAVE ONE CLIENT, A NURSING HOME CHAIN, WHICH DUE TO ITS SIGNIFICANT CONTRIBUTION TO OUR TOTAL REVENUES, WE CONSIDER A MAJOR CLIENT.
An investment in our common stock involves a high degree of risk.  The risk factors listed below are those that we consider to be material to an investment in our common stock and those which, if realized, could have material adverse effects on our business, financial condition or results of operations as specifically discussed below.  We believe these are our most significant risk factors, which may be beyond our control and could cause results to differ significantly from projection.  If such an adverse event occurs, the trading price of our common stock could decline, and you could lose all or part of your investment.  Before you invest in our common stock, you should be aware of various risks, including those described below.  You should carefully consider these risk factors, together with all of the other information included or incorporated by reference in this prospectus, before you decide whether to purchase our common stock.  This section includes or refers to certain forward-looking statements.  You should refer to the explanation of the qualifications and limitations on such forward-looking statements discussed on page 6.
We have one client, a nursing home chain, which due to its significant contribution to our total revenues, we consider a major client.
Our major client accounted for 19%15% of our 2008 total consolidated revenues and 13% of our total consolidated revenues for each of the six monthsmonth period ended June 30, 20062009.  Such revenue consists of 14% and the year ended December 31, 2005 and accounted for 17% and 27% of our Housekeeping segment and Food segment revenues, respectively, for the six months ended June 30, 2006 and for 18% and 27% of our Housekeeping segment and Food segment revenues, respectively, for the year ended December 31, 2005. At2008, and 13% and 12% of our Housekeeping and Food revenues, respectively, for the six month period ended June 30, 2009.  Additionally, at June 30, 2009 and December 31, 2005,2008, amounts due from such client represented less than 1% of our accounts receivable balance.  This client completed its previously announced merger on March 14, 2006. Our relationship with the successor entity remains under the same terms and conditions as established prior to the merger. Although we expect to continue the relationship with this client's successor,client, there can be no assurance thereof, andthereof.  The loss of such client, or a significant reduction in the loss ofrevenues we receive from such client, would have a material adverse effect on the results of operations of our two operating segments.  In addition, if such client's successorclient changes its payment terms it would increase our accounts receivable balance and have a material adverse effect on our cash flows and cash and cash equivalents. OUR CLIENTS ARE CONCENTRATED IN THE HEALTH CARE INDUSTRY.
Our clients are concentrated in the health care industry which, among other things, is subject to significant government funding.
We provide our services primarily to providers of long-term care.  The Balance Budget Act of 1997 changed Medicare policy inCongress has enacted a number of ways, most notablymajor laws during the phasingpast decade that have significantly altered, or may alter, overall government reimbursement for nursing home services.  In addition, Congress may in effective July 1, 1998 of a Medicare Prospective Payment Systemthe future consider legislation that may alter overall governmental reimbursement for skilled nursing facilities which significantly changed the manner and the amounts of reimbursement they receive.

These factors, in addition to delays in payments from clients have resulted in, and could continue to result in, significant additional bad debts in the near future.  In addition,

We have clients located in certain states which have had and may continue to experience significant budget deficits and such deficits may result in reduction of reimbursements to nursing homes.
Certain states, in which our clients are located, have significant budget deficits as a result of lower than projected revenue collections and increased demand for the prospectsfunding of entitlements.  As a result of these and other adverse economic factors, some state Medicaid programs are reconsidering previously approved increases in nursing home reimbursement or are considering delaying those increases.  A few states have indicated it is possible they will run out of cash to make entitlement payments, including Medicaid payments to nursing homes.  Any disruption or delay in the distribution of Medicaid and related payments to our clients will adversely affect their liquidity and impact their ability to pay us as agreed upon for legislative relief are uncertain. the services provided.

WE HAVE A PAID LOSS RETROSPECTIVE INSURANCE PLAN FOR GENERAL LIABILITY AND WORKERS' COMPENSATION INSURANCE. workers’ compensation insurance.
Under our insurance plans for general liability and workers'workers’ compensation, predetermined loss limits are arranged with our insurance company to limit both our per occurrence cash outlay and annual insurance plan cost.  We regularly evaluate our claims pay-out experience, present value factor and other factors related to the nature of specific claims in arriving at the basis for our accrued insurance claims estimate.  Our evaluation is based primarily on current information derived from reviewing our claims experience and industry trends.  In the event that our claims experience and/or industry trends result in an unfavorable change, it would have an adverse effect on our results of operations and financial condition. WE PROVIDE SERVICES IN 45 STATES AND ARE SUBJECT TO NUMEROUS LOCAL TAXING JURISDICTIONS WITHIN THOSE STATES.
We provide services in 47 states and are subject to numerous local taxing jurisdictions within those states.
The taxability of our services is subject to various interpretations within the taxing jurisdictions of our markets.  Consequently, in the ordinary course of business, a jurisdiction may contest our reporting positions with respect to the application of its tax code to our services.  A jurisdiction'sjurisdiction’s conflicting position on the taxability of our services could result in additional tax liabilities which we may not be able to pass on to our clients or could negatively impact our competitive position in the respective location.  WE PRIMARILY PROVIDE OUR SERVICES PURSUANT TO AGREEMENTS WHICH HAVE A ONE YEAR TERM, CANCELABLE BY EITHER PARTY UPONAdditionally, if we or one of our employees fail to comply with applicable tax laws and regulations we could suffer civil or criminal penalties in addition to the delinquent tax assessment.

Our business and financial results could be adversely affected by unfavorable results of material litigation or governmental inquiries.
We may from time to time become the subject in the ordinary course of business to material legal action related to, among other things, general liability and employee-related matters, as well as inquiries from governmental agencies.  Legal actions could result in substantial monetary damages as well as adversely affecting our reputation and business status with our clients.  As a result of the risks and consequences of legal actions, our results of operations and financial position could be adversely affected.

We do not enter into long-term contractual agreements with our clients for the rendering orof our services.  Consequently, our clients have the ability tocan unilaterally decrease the amount of services we provide or terminate all services pursuant to the terms of our service agreements.  Any loss of a significant number of clients during the first year of providing services, for which we have incurred significant start-up costs or invested in an equipment installation, could in the aggregate materially adversely affect our consolidated results of operations and financial position. WE ARE DEPENDENT ON THE MANAGEMENT EXPERIENCE OF OUR KEY PERSONNEL.
We are dependent on the management experience of our key personnel.
We manage and provide our services through a network of management personnel, from the on-site facility manager up to the executive officers of the company.  Therefore, we believe that our ability to recruit and sustain the internal development of managerial personnel is an important factor impacting future operating results and our ability to successfully execute projected growth strategies.  Our professional management personnel are the key personnel in maintaining and selling additional services to current clients and obtaining new clients. 3 WE MAY BE UNABLE TO SUCCESSFULLY INTEGRATE THE OPERATIONS OF SUMMIT SERVICES GROUP, INC. WITH OUR OPERATIONS.
We may be adversely affected by inflationary or market fluctuations in the cost of products consumed in providing our services or our cost of labor.
The prices we pay for the principal items we consume in performing our services are dependent primarily on current market conditions affecting such items.  Additionally, our cost of labor may be influenced by unanticipated factors in certain market areas, governmental legislative actions or increases in collective bargaining agreements of our clients, to which we assent.  Although we endeavor to pass on such increased costs to our clients, any inability or delay in passing on such increases in costs could negatively impact our profitability.
Our investments represent a significant amount of our assets that may be subject to fluctuating and even negative returns depending upon interest rate movements and financial market conditions.
Although management believes we have a very prudent and responsible investment policy, we are exposed to fluctuations in interest rates and in the market values of our investment portfolio which could adversely impact our financial condition and results of operations.

Market expectations are high and rely greatly on execution of our growth strategy and related increases in financial performance.
Management believes the historical price increases of our Common Stock reflect high market expectations for our future operating results.  In particular, our ability to attract new clients, through organic growth or acquisitions, has enabled us to execute our growth strategy and increase market share.  If, in the event we are not able to continue historical client and revenue growth rates, our operating performance may be adversely affected.  Any failure to meet the market’s high expectations for our revenue and operating results may have an adverse effect on the market price of our Common Stock.
We may be unable to successfully integrate the operations of Contract Environmental Services, Inc. with our operations.
We acquired Summitthe assets of Contract Environmental Services, Group, Inc. pursuant to an agreement and plan of merger dated September 18, 2006.on May 1, 2009.  Integration of the operations of SummitContract Environmental Services, Group, Inc. with our operations involve, among others, the following risks: o substantial retention of Summit Services Group, Inc.'s existing clients; o unanticipated or excessive diversion of management's resources; o integration of new operations and personnel; and o failure to achieve expected financial results.

substantial retention of Contract Environmental Services, Inc.’s existing clients;
·      
unanticipated or excessive diversion of management’s resources;

integration of new operations and personnel; and

failure to achieve expected financial results.
Because of these and other risks, our acquisition of SummitContract Environmental Services, Group, Inc. could have a material adverse effect on our business, financial condition and results of operations.  If we are unable to successfully address any of these risks, our overall business could be harmed. WE MAY IN GENERAL BE ADVERSELY AFFECTED BY INFLATIONARY OR MARKET FLUCTUATIONS IN THE COST OF PRODUCTS CONSUMED IN PROVIDING OUR SERVICES OR OUR COST OF LABOR. The prices we pay for the principal items we consume in performing our services are dependent primarily on current market price. Additionally, our cost of labor may be influenced by unanticipated factors in certain market areas or increases in collective bargaining agreements of our clients, to which we assent. Although we endeavor to pass on, as price increases, such increased costs, any inability or delay in passing on such increases in costs could negatively impact our profitability.

ITEM 15.
Indemnification of Directors and Officers.
Sections 1741 through 1750 of Subchapter C of Chapter 17 of the Pennsylvania Business Corporation Law (the "BCL") contain, among other things, provisions for mandatory and discretionary indemnification of a corporation's directors, officers and other personnel.
Under Section 1741, unless otherwise limited by its by-laws, a corporation has the power to indemnify directors and officers under certain prescribed circumstances against expenses (including attorney's fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with a threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative, to which any of them is a party or threatened to be made a party by reason of his being a representative, director or officer of the corporation or serving at the request of the corporation as a representative of another corporation, partnership, joint venture, trust or other enterprise, if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action or proceeding by judgment, order, settlement or conviction or upon a plea of nolo contendere or its equivalent does not of itself create a presumption that the person did not act in good faith and in a manner that he reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal proceeding, had reasonable cause to believe that his conduct was unlawful.
Section 1742 provides for indemnification with respect to derivative actions similar to that provided by Section 1741.  However, indemnification is not provided under Section 1742 with respect to any claim, issue or matter as to which a director or officer has been adjudged to be liable to the corporation unless and only to the extent that the court of common pleas of the judicial district embracing the county in which the registered office of the corporation is located or the court in which the action was brought determines upon application that, despite the adjudication of liability but in view of all of the circumstances of the case, a director or officer is fairly and reasonably entitled to indemnity for the expenses that the court deems proper. II-1
Section 1743 provides that indemnification against expenses is mandatory to the extent that the director or officer has been successful on the merits or otherwise in defense of any such action or proceeding referred to in Section 1741 or 1742.
II- 1

Section 1744 provides that unless ordered by a court, any indemnification under Section 1741 or 1742 shall be made by the corporation as authorized in the specific case upon a determination that indemnification of directors and officers is proper because the director or officer met the applicable standard of conduct, and such determination will be made by the Board of Directors by a majority vote of a quorum of directors not parties to the action or proceeding; if a quorum is not obtainable or if obtainable and a majority of disinterested directors so directs, by independent legal counsel; or by the shareholders.
Section 1745 provides that expenses incurred by a director or officer in defending any action or proceeding referred to in the Subchapter may be paid by the corporation in advance of the final disposition of such action or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined by a court having jurisdiction that he is not entitled to be indemnified by the corporation.
Section 1746 provides generally that except in any case where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness, the indemnification and advancement of expenses provided by the Subchapter shall not be deemed exclusive of any other rights to which a director or officer seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of shareholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding that office.
Section 1747 also grants a corporation the power to purchase and maintain insurance on behalf of any director or officer against any liability incurred by him in his capacity as officer or director, whether or not the corporation would have the power to indemnify him against the liability under this Subchapter of the BCL.
Sections 1748 and 1749 apply the indemnification and advancement of expenses provisions contained in the Subchapter to successor corporations resulting from consolidation, merger or division and to service as a representative of a corporation or an employee benefit plan.
The foregoing provisions substantially overlap the provisions of the Pennsylvania Directors' Liability Act, 42 Pa. C.S. ss. 8365, which are also applicable to the Company.
Article XI of the Company's By-laws provides, in part, that the Company shall indemnify its directors, officers, employees and agents to the fullest extent permitted by the BCL.
Article XII of the Company's By-laws provides, in part, that: "A
"A Director shall not be liable for monetary damages as such for any action taken, or any failure to take action, unless (1): the director has breached or failed to perform the duties of his office under Section 8363 of the Pennsylvania Consolidated Statutes and the breach or failure to perform constitutes self-dealing, willful misconduct or recklessness; provided, however, that the foregoing provision shall not relieve a director of responsibility or liability of a director pursuant to any criminal statute or for the payment of taxes pursuant to local, state or Federal law."

(2) 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 FIDEbona fide offering thereof.
(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.
(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:
If the registrant is relying on Rule 430B:
(a) 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
(b) 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; or II-4
(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 registration will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
II- 4

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

(c) 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 Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(1) For 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.
(2) 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.
