COLLATERAL SECURITY AGREEMENT

      THIS  COLLATERAL  SECURITY  AGREEMENT  (this  "Agreement")  is  made as of
February 15, 2006 by and between ALLAN ROBBINS,  an individual  residing at 1575
Bayshore Boulevard,  Rochester,  NY 14622 ("Lender") and INFINITE GROUP, INC., a
Delaware  corporation  with its principal office at 595 Blossom Road, Suite 309,
Rochester, NY 14610 ("Borrower").

      WHEREAS,  the Borrower has  executed and  delivered to the Lender  certain
Promissory Notes (the "Notes") as more  specifically  identified on the attached
Schedule A; and

      WHEREAS,  in consideration of the Lender's  agreement to lend money to the
Borrower,  the Borrower has agreed to secure its debts and obligations under the
Note (the "Obligations"), with the pledge, assignment, transfer and grant of the
security interest as provided in this Agreement.

      NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
contained herein, the parties agree as follows:

      1. Grant of a Security Interest. As inducement for Lender to lend money to
Borrower, the Borrower hereby grants to Lender, as collateral for the payment or
repayment of Borrower's  obligations  under the Note, a security  interest under
the  Uniform  Commercial  Code for the State of New York,  in all of  Borrower's
assets,  presently  existing  or  hereafter  arising,  now  owned  or  hereafter
acquired,  and proceeds thereof (the  "Collateral"),  to be and remain effective
during any time when any indebtedness or Obligations  whatsoever exist under the
Notes.

      2. Obligations Secured. This pledge,  assignment,  transfer and grant of a
security  interest  is made to secure to Lender the prompt and full  payment and
performance of all of the Obligations in accordance with the terms of the Note.

      3.  Representations  and  Warranties.  The  Borrower  hereby  warrants and
represents to the Lender and covenants and agrees with the Lender as follows:

            a.    The Borrower is the record owner of the  Collateral,  free and
                  clear  of any  and  all  claims,  liens,  security  interests,
                  attachments  and  encumbrances  except  those set forth in the
                  attached Schedule B.

            b.    The Borrower has full power,  right and  authority to execute,
                  deliver and perform the pledge, assignment, transfer and grant
                  of the  security  interest  set forth  herein  and no  further
                  action  is  necessary  on the part of  Borrower  to make  this
                  Agreement  valid and binding upon Borrower in accordance  with
                  its terms.

            c.    The execution,  delivery,  nor performance by Borrower of this
                  Agreement  and/or the Note will not conflict  with,  or result
                  in, a violation or breach of any terms or  provisions  of, nor
                  constitute a default under,  the Certificate of  Incorporation
                  of Borrower, or under an indenture,  mortgage,  deed of trust,
                  or other  contract or agreement to which  Borrower is a party,
                  by which it or its property is bound.

      4. Release of Collateral Upon Borrower's Payments.  The parties agree that
upon  the  Borrower's  payment  to  the  Lender  and  satisfaction  of  all  the
Obligations under the Notes in accordance with the Notes, or upon the conversion
of the Notes in their  entirety in accordance  with the provisions of the Notes,
that the Collateral and the security  interest created therein shall be released
from the provisions of this Agreement.

      5.  Covenants.  Notwithstanding  any  provision  herein and as long as any
amount of the  principal  and  interest  of the Note  remains  unpaid,  Borrower
covenants and agrees that it shall:

            a.    Not sell,  transfer,  convey, lease or encumber (other than as
                  expressly  contemplated  by this  Agreement)  any  part of the
                  Collateral, except that Borrower may grant a security interest
                  in the  Collateral  provided it is in a position  secondary to
                  this Collateral Security Agreement and does not interfere with
                  the  terms  of  this  agreement  and  Borrower  may  sell  and
                  substitute Collateral in the ordinary course of business.

            b.    Pay when due all taxes,  assessments and other  liabilities of
                  every nature which may be levied or assessed  against Borrower
                  or the  Collateral,  except and so long as  contested  in good
                  faith.

            c.    In the event that  Borrower  shall be sued or any  substantial
                  claims made against it which could materially adversely affect
                  its  financial  condition  or its  ability  to pay the Note or
                  comply with and fulfill all the terms and  provisions  of this
                  Agreement,  give written notice to Lender within ten (10) days
                  of knowledge thereof, containing sufficient details to apprize
                  Lender of the nature thereof.

            d.    Defend the  Collateral  against  all claims and demands of all
                  persons claiming the same or any interest therein, which exist
                  or are  caused by facts and  circumstances  arising  after the
                  date hereof.

            e.    Promptly  notify  Lender of any change in the  location of the
                  Collateral.

            f.    Not use the  Collateral in violation of any  applicable  laws,
                  statutes, regulations or ordinances.

Any and all of the  foregoing  may from  time to time be waived  in  writing  by
Lender.

      6. Events of Default.  Upon Borrower's  breach of any term or condition of
this Agreement  and/or the Note (an "Event of Default"),  Borrower  shall,  upon
giving Lender ten (10) days advance  written  notice and  Borrower's  failure to
cure an event of default within said notice period,  be entitled to exercise any
and all available rights including, but not by way of limitation, the following:

            a.    The right to declare all obligations secured by this Agreement
                  immediately due and payable.

            b.    All of the  rights,  remedies  and powers of a secured  party,
                  including without  limitation all rights,  remedies and powers
                  under the  provisions the Uniform  Commercial  Code as adopted
                  and set  forth in the  statutes  of the State of New York (the
                  "UCC") and, to the extent that a reasonable  notice of sale or
                  disposition  is required  under the UCC,  with  respect to any
                  portion of the Collateral,  that  requirement  shall be met if
                  such notice is mailed by certified or registered mail, postage
                  prepaid,  to the Borrower at its address  above at least seven
                  (7) days before the time of the sale or other disposition.

            c.    The right to seize the Collateral covered by this Agreement in
                  such order and such amounts as Creditor shall choose.

                                       2
<PAGE>

            d.    The right to have a receiver appointed by a court of competent
                  jurisdiction  to  collect,  gather and  possess  any assets of
                  Borrower and to operate Borrower's business.

            e.    The right to collect from Borrower any and all costs  incurred
                  by Lender in  exercising  its  rights  under  this  Agreement,
                  including but not limited to collection  costs and  reasonable
                  attorneys' fees.

Debtor further  understands and agrees that any breach of any provisions  hereof
by Borrower will cause  irreparable  harm and damage to Lender.  Borrower hereby
expressly  agrees  that  Lender  shall be  entitled  to  enjoin  any  actual  or
threatened  violation of any of the provisions of this Agreement or the Note. In
addition to injunctive relief, Lender may recover damages for any loss caused by
a violation or breach of any of the provisions  thereof.  All remedies hereunder
are  cumulative  and not exclusive of any other  remedies  provided at law or in
equity.  Upon the occurrence of an Event of Default,  after having  received ten
(10) days advance  written notice and  Borrower's  failure to cure such Event of
Default  within  said  notice  period,  Borrower  appoints  Lender,  as the duly
appointed  attorney-in-fact  of Borrower,  with full power of  substitution  and
grants to Lender or its  permitted  assignee  the full power and right to do any
and all things  necessary  to be done in and about the  Collateral  as fully and
effectually as Borrower might or could do but for this  appointment,  and hereby
ratifies all that said attorney-in-fact shall lawfully do or cause to be done by
virtue hereof. In addition to and  notwithstanding  the foregoing,  in the event
that an Event of Default is uncured with the 10-day notice period,  the Borrower
covenants and agrees to assist the Lender to the extent  necessary to render the
Collateral  suitable for sale,  and to assist the Lender in connection  with the
liquidation  and sale of the  Collateral in as  expeditious a manner as possible
under the circumstances. Neither Lender, its permitted assignee nor their agents
shall be  liable  for any acts or  omissions  or for any  error of  judgment  or
mistake of fact or law in its capacity as such  attorney-in-fact.  This power of
attorney is coupled with an interest and shall be irrevocable until the Note has
been paid in full.

      7. Waivers by the Borrower.  Except as otherwise  specifically provided in
this Agreement and the Note, the Borrower hereby waives all presentment, demands
for performance, notice of nonperformance, notice of any indulgences, notices of
extensions or renewals relating to the Obligations,  any requirement of diligent
performance  on the Lender's part in the  enforcement of its rights with respect
to the  Obligations  and  Collateral,  any and all  notices  of  every  kind and
description  which may be required to be given to the Lender in connection  with
the Obligations,  this Agreement or the Collateral.  No delay or omission on the
Lender's  part in  exercising  any right or remedy  under this  Agreement  shall
operate  as a waiver of such  right or remedy or any other  right or  remedy.  A
waiver of any one  occasion  shall not be construed as a bar to or waiver of any
right on any future occasion.

      8.  Assignment.  Neither  party  shall  assign its  rights or  obligations
hereunder  without the prior written consent of the other party.  This Agreement
shall be  binding  upon and  inure  to the  benefit  of the  parties  and  their
successors and permitted assigns.

      9.  Counterparts.  This  Agreement  may  be  executed  in  any  number  of
counterparts,  each of which, when executed,  shall be deemed to be an original,
and all of which together shall be deemed to be one and the same instrument.

      10. Severability.  All provisions of this Agreement shall be considered as
separate  terms  and  conditions,  and in the  event  that any one shall be held
illegal,  invalid or unenforceable,  all other provisions hereof shall remain in
full force and effect as if the illegal, invalid or unenforceable provision were
not a part hereof,  provided,  however,  that  whenever  possible,  the illegal,
invalid or  unenforceable  provision shall be deemed modified and amended to the
extent that it may thereby be made legal, valid and enforceable. This Agreement,
all provisions and supplements  thereof,  all amendments thereto,  and all acts,
transactions and agreements thereunder, and all duties, obligations, rights, and
remedies  of the  parties  thereto,  shall be  governed  as to  their  validity,
enforcement,  construction and effect,  and in all other respects by the laws of
the State of New York.

                                       3

      11. Notices. Any notice or demand or other communication which is required
or provided by any  provision of this  Agreement or any  agreement,  document or
instrument  executed  pursuant hereto shall be deemed to have been  sufficiently
given for all  purposes if  hand-delivered  or sent by  certified  mail,  return
receipt  requested to the parties at the addresses shown in the preamble to this
Agreement.

      IN WITNESS  WHEREOF,  the parties  have caused this  Agreement  to be duly

                       CODE OF BUSINESS CONDUCT AND ETHICS

EXHIBIT 10.11

In the wake of several large corporate scandals and bankruptcies, the SEC and
other governing bodies have implemented additional controls and procedures for
publicly reporting companies. We have always prided ourselves on maintaining the
highest ethical standards, and we have always had certain policies essential to
maintaining our high standards. We believe that our directors, officers and
employees are aware of our commitment to ethics, and that they have worked and
will work hard to meet it. However, to formalize our commitment to certain
critical policies cited by the SEC, our Board of Directors has adopted this Code
of Business Conduct and Ethics. This Code of Business Conduct and Ethics does
not summarize all of our policies. Our employees must also comply with our other
policies set out in our Employee Handbook and elsewhere.

1.    COMPLYING WITH LAWS. We should respect and comply with all applicable
      laws, rules and regulations in the conduct of our business. This includes
      the laws, rules and regulations of the U.S. and each foreign country,
      state, county, city and other jurisdiction in which we conduct business.
      This is true even if a supervisor or anyone in management has directed
      otherwise. If you are ever unsure about the legal course of action, please
      immediately request assistance from your supervisor, or Kevin Lee, our
      Chief Financial Officer.

      The laws with which we comply include "insider trading laws" relating to
      transactions in our stock. Some of our specific responsibilities are set
      out in our Statement of Company Policy on Insider Trading and Public
      Disclosure of Information. Generally, we are not permitted to buy, sell or
      otherwise trade in our securities without specific permission from our SEC
      compliance officer, and then only during specified "window" periods in the
      case of directors and senior executives. Please carefully read our
      policies and procedures regarding insider trading in full and contact
      Kevin Lee, our Chief Financial Officer if you have questions about it.

2.    CONFIDENTIALITY. We must maintain the confidentiality of all sensitive
      information entrusted to us, including all non-public information whose
      disclosure might be of use to our competitors, or harmful to us or our
      customers. Please carefully read our policies regarding Confidentiality
      and Non-Solicitation and contact Kevin Lee if you have questions about it.

3.    CORRUPT PRACTICES. In accordance with the U.S. Foreign Corrupt Practices
      Act and our policies, we are strictly prohibited from giving anything of
      value, directly or indirectly, to foreign government officials or foreign
      political candidates in order to obtain or retain business. In addition,
      we are strictly prohibited from giving U.S. government officials business
      gratuities or gifts. The U.S. government can and has imposed criminal
      sanctions on individuals and entities that have improperly given gifts to
      U.S. government personnel, and the promise, offer or delivery to an
      official or employee of the U.S. government of a gift or other gratuity
      would not only violate our policies, but might also be a criminal offense.
      Please contact Kevin Lee if you believe improper gifts have been, are
      being, or will be made by our employees or directors.

4.    FAIR DEALING. We seek to outperform our competition fairly and honestly
      and seek competitive advantages through superior performance. We do not
      use unethical or illegal business practices to compete. Stealing
      proprietary information, possessing trade secret information that was
      obtained without the owner's consent, or inducing such disclosures by past
      or present employees of other companies is prohibited. We endeavor to deal
      fairly with our customers, suppliers, competitors, officers and employees.
      We should never take unfair advantage of anyone through manipulation,
      concealment, abuse of privileged information, misrepresentation of
      material facts or any other unfair dealing practice.

<PAGE>

5.    PUBLIC COMPANY REPORTING. As a public company, our filings with the SEC
      must be accurate and timely. Whether or not you are directly involved in
      that process, you have several responsibilities:

      o     Depending upon your position, you may be called upon to provide
            information to assure that our public reports are complete, fair and
            understandable. We expect you to take this responsibility very
            seriously and to provide prompt accurate answers to inquiries
            related to our public disclosure requirements.

      o     Our books, records, accounts and financial statements must be
            maintained in reasonable detail, must appropriately reflect our
            transactions and must conform both to applicable legal requirements
            and to the Company's system of internal controls. Unrecorded or "off
            the books" funds or assets should not be maintained unless permitted
            by applicable law or regulation. Additionally, records should always
            be retained or destroyed consistent with our past record retention
            practices.

      o     Our public reports should fairly and accurately reflect what is
            happening at our Company. If you believe they do not, you have a
            responsibility to bring your concerns to the attention of senior
            management or the board.

      Because of the importance of this issue, our Board of Directors has
      adopted the following resolution, which is binding on everyone at the
      Company:

            "Every employee of or consultant to the Company who has, or who
            hears expressed by another person, any concerns about the manner in
            which the Company's financial statements or public reports are
            prepared, the sufficiency of its internal financial controls, the
            honesty or competence of its financial management or independent
            auditors or any other matter within the purview of the Board of
            Directors is directed and strongly encouraged to report the matter
            promptly to any member of the Board. The Board will attempt to keep
            the name of the person reporting the potential issue confidential to
            the extent requested by that person and not inconsistent with the
            best interests of the Company. The Board will not tolerate
            retaliation against any person who reports potential issues to the
            Board in good faith."

      Accordingly, if you have concerns regarding any accounting or auditing
      matters, you may (but are not required to) consult with your supervisor or
      any of our executive officers if you are comfortable doing so. But, unless
      the issues are fully resolved to your satisfaction, or if you are not
      comfortable discussing the matter with our management, you are required to
      submit your concerns or complaints (anonymously, confidentially or
      otherwise) to the Board of Directors. This is true even if your supervisor
      or anyone in management has directed you not to do so. If you ask, we will
      keep your name confidential unless this would violate applicable law or
      our responsibilities to others.

6.    CONFLICTS OF INTEREST. You should avoid conflicts of interest with the
      Company except under guidelines approved by our Board of Directors or a
      committee of our Board. Please refer to our policies and procedures
      regarding conflicts of interest and if you become aware of a conflict of
      interest on the part of anyone at the Company, you must report it to your
      supervisor or directly to Kevin Lee or the Board of Directors.

<PAGE>

      A "conflict of interest" exists whenever your private interests interfere
      or conflict in any way (or even appear to interfere or conflict) with our
      interests. A conflict of interest can arise when you take actions or have
      interests that may make it difficult to perform your work for us
      objectively and effectively. Conflicts of interest may also arise when
      you, or members of your family, receives improper personal benefits as a
      result of your position with us, regardless of from where those benefits
      are received.

      Specifically, it is a conflict of interest for you or a member of your
      immediate family to work simultaneously for one of our competitors,
      customers or suppliers, even as a consultant or board member, to receive
      any form of compensation (including loans or "gifts") from any person with
      whom we are doing business or to own an undisclosed interest in any
      supplier to us (other than an interest of less than 1% in a public
      company). If you or a member of your immediate family receives any
      payments from the Company or any person or entity connected or doing
      business with the Company, it must be disclosed and approved by the
      Company. (This, of course, does not include salary and bonus payments made
      though our payroll, stock option grants under our employee stock option
      plans, or normal business expense reimbursements.)

      Similarly, you owe us a duty to advance our legitimate interests when the
      opportunity to do so arises. You are prohibited from (a) taking for
      yourself personally opportunities that properly belong to the Company or
      are discovered through the use of our property, information or your
      position with us; (b) using corporate property, information or position
      for personal gain; or (c) competing with us.

      Ordinarily, the best policy will be to avoid any direct or indirect
      business connection with our customers, suppliers or competitors, except
      on our behalf. However, regardless of how "natural" or "innocent" a
      conflict may seem, you must report it and can proceed only if the
      relationship is approved in writing by Kevin Lee and the then current
      Chairman of our Board of Directors. If you have any questions about
      whether a situation is a conflict of interest, you should raise the issue
      with your supervisor or directly with Kevin Lee or the then current
      Chairman of our Board of Directors.

7.    REPORTING ANY ILLEGAL OR UNETHICAL BEHAVIOR. The Company can be held
      criminally liable if one of its employees, directors or agents commits
      certain crimes. Accordingly, you must promptly report any knowledge or
      information about employment-related conduct by another employee, director
      or agent of the Company that you reasonably believe to be a crime, a
      material violation of law or regulation, a dishonest act (including
      misappropriation of funds or anything of value from the Company or the
      improper recording of the Company's assets or liabilities), a breach of
      trust or any other conduct that might affect the reputation of the
      Company. You must report the relevant facts promptly to your supervisor.
      If the situation cannot be resolved, or if you feel uncomfortable using
      internal resources for reporting your concerns, you must report the matter
      as directed above.

8.    SPECIAL REQUIREMENTS FOR OFFICERS AND DIRECTORS. Any consent or waiver
      with respect to this Code which involves an Officer or Director of the
      Company must be approved by a majority of disinterested directors on our
      Board of Directors.

<PAGE>

9.       NO RETALIATION. We will not tolerate retaliation of any kind against
         any person who in good faith reports to us potential issues relating to
         violations of law or this Code.

This Code only be amended, modified or waived by our Board of Directors or its
authorized committee, subject to the disclosure and other provisions of the
Securities Exchange Act of 1934.

If you are ever unsure about whether some action would be consistent with this
Code of Business Conduct and Ethics, you should ask us. Similarly, any time you
encounter a situation and you are unsure what to do, you agree to tell us and
ask for help.
