                    SEPARATION AGREEMENT AND GENERAL RELEASE


                  This SEPARATION AGREEMENT AND GENERAL RELEASE ("Agreement") is
made and entered into by and between Paul Ludwig ("Ludwig"), on the one hand,
and Advanced Photonix Inc. ("API") on the other.

                                    RECITALS:

                  A.       Ludwig has been employed by API since August 2002,
and the parties wish to terminate his employment with API effective as of August
31, 2006 (the "Separation Date").

                  B.       The parties desire amicably to resolve fully and
finally all issues and claims that Ludwig may have with API and others released
herein, including, but not limited to, any matters or claims arising out of or
related to Ludwig's employment with API, Ludwig's membership on API's Board of
Directors, or any other relationship with API or any other API Releasee, and the
termination of those relationships.

                  NOW, THEREFORE, in consideration of the premises and promises
contained in this Agreement, the parties agree as follows:

                  SECTION 1 -- NON-ADMISSION OF LIABILITY OR WRONGDOING.


                  The parties acknowledge that this Agreement reflects their
desire to terminate all aspects of their relationship (except as otherwise
provided in this Agreement) in an orderly and amicable fashion. The parties in
no way acknowledge any fault or liability to the other party or any other person
or entity, and this Agreement shall not be construed as an admission by either
party or any other person or entity of any fault or liability to any party or
any other person or entity.

                  SECTION 2 -- CESSATION OF EMPLOYMENT AND OTHER RELATIONSHIPS.


                  Ludwig hereby resigns, and API hereby accepts Ludwig's
resignation, as a director, officer and employee of API and of all subsidiaries
of API effective as of the opening of business on the Separation Date. API will
not contest any claim initiated by Ludwig for unemployment insurance benefits
and will characterize his departure from API as a separation from employment.

                  SECTION 3 -- BENEFITS TO LUDWIG.


                  Between the date hereof and the Separation Date, Ludwig will
continue to be employed by API on the same terms and conditions as he is
currently employed by API and in such capacity shall continue to receive
compensation at the same rate as he is currently paid and shall continue to be
eligible to participate in all benefit plans of API on the same terms as he now
participates therein. Following the Separation Date, API will,

                                                                     ---------

and withholdings, all of which will be reported on the appropriate tax forms as
determined by API:

                  (a)               $10,160.88 representing approximately 8
months of API subsidy for the group health insurance Ludwig was enrolled in as
of the date hereof. This payment will be mailed to Ludwig within 5 days after
the Separation Date.

                  (b)               $123,344 representing approximately 8
months of Ludwig's base salary, payable in eight substantially equal
installments of $15,418 each. The first $15,418 installment will be mailed to
Ludwig on or about October 3, 2006. An additional installment will be mailed to
Ludwig on or about the third day of each of the next 7 months with the last
installment to be mailed on or about May 2, 2007.


                  (c)               The full amount, if any, of any accrued but
unpaid vacation and any accrued and unpaid compensation owing to Ludwig as at
the Separation Date which will be payable to Ludwig not later than 5 days after
the Separation Date.

                  In addition, API will pay for Ludwig to receive, from and
after the date hereof, outplacement assistance services selected by API from Lee
Hecht Harrison, Right Associates, or another mutually agreeable company, at a
cost not to exceed $20,000.00.

                  Ludwig acknowledges that the benefits to be received by him
under the provisions of this Section 3 are in addition to any benefits to which
he would otherwise be entitled to receive in connection with his employment or
the termination thereof.

                  SECTION 4 -- RESPONSIBILITY FOR TAXES.


                  Ludwig agrees that he solely is responsible for all of his tax
obligations, including, but not limited to, all payment obligations, which may
arise as a consequence of this Agreement, and all payments made to Ludwig
hereunder shall be subject to tax withholding as required by law.

                  SECTION 5 -- COMPLETE RELEASE BY LUDWIG.


                  As a material inducement to API to enter into this Agreement,
Ludwig irrevocably and unconditionally releases and forever discharges API, all
of API's current and former parents, subsidiaries, related companies,
partnerships, joint ventures, or other affiliates, and, with respect to each of
them, their predecessors and successors; and, with respect to each and all of
the foregoing entities, all of their respective past, present, and future
employees, officers, directors, stockholders, owners, representatives, assigns,

                                                                     ---------

successors (collectively along with API, the "API Releasees"), from any and all

                  The term "Claims" includes all charges, claims, complaints,
liabilities, obligations, promises, agreements, controversies, damages, actions,
causes of action, suits, rights, demands, costs, losses, debts, and expenses
(including attorneys' fees and costs actually incurred) or similar rights of any
nature whatsoever, known or unknown, which Ludwig now has or claims to have, or
which Ludwig at any time heretofore had or claimed to have, or which Ludwig at
any time hereafter may have or claim to have against each or any of the API
Releasees, arising out of or related to any act, omission, event, fact or other
thing which existed or occurred (i) on or prior to the date Ludwig signs this
Agreement or (ii) in the event but only in the event that Ludwig accepts any
payment made to him pursuant to Section 3 hereof, on or prior to the Separation
Date. This includes but is not limited to a release of all rights and claims
Ludwig may have under:

a)    Anti-Discrimination Statutes, such as the Wisconsin Fair Employment Act

      national origin, ancestry, disability, sexual orientation, marital status,
      sex or age); the Age Discrimination in Employment Act (prohibiting age
      discrimination); Title VII of the Civil Rights Act of 1964 (prohibiting

      discrimination); 42 U.S.C. Sec. 1982 (prohibiting discrimination);
      Executive Order 11246 (prohibiting race, color, religion, sex and national

      discrimination); the Equal Pay Act (prohibiting paying males and females
      different amounts for equal work); and the Americans With Disabilities Act
      (prohibiting discrimination based on disability).

b)    Federal and State Employment Statutes, such as the Fair Labor Standards

      Security Act of 1974 (protecting employee benefits); the National Labor
      Relations Act (protecting the right to engage in union activity); the

      prohibiting discrimination in employment or otherwise, enforcing express
      or implied contracts, requiring employers to deal fairly or in good faith,
      or restricting an employer's right to terminate employees. Ludwig also
      releases any and all other claims, known and unknown, which he may have
      for breach of contract, express or implied; breach of the covenant of good
      faith and fair dealing; and retaliation, defamation, conspiracy,

                                                                     ---------

       infliction of emotional distress, invasion of privacy, misrepresentation,
       or any other tort; and

d)    Benefit Plans. Ludwig acknowledges that he will cease to be eligible to
      participate in any stock option, bonus, incentive compensation,
      commission, medical, dental, life insurance, retirement, and other
      compensation or benefit plans of API or any other party released herein as
      of his Separation Date. Ludwig releases all rights under any such plan,
      except he will retain any right he has to COBRA continuation coverage as
      to any API-provided medical, dental, or vision plan in which he
      participated as of his Separation Date. If Ludwig desires to elect COBRA
      continuation coverage, he must timely elect it and timely pay all required
      contributions. Ludwig also will retain all vested benefits under all API
      qualified retirement plans, and all rights associated with those benefits,
      as determined under the official terms of those plans. Ludwig acknowledges
      that he will cease vesting in any stock option or similar API plan as of
      his Separation Date and any rights he may have shall be determined under
      the official terms of such plan. It is provided, however, that assuming
      that this Agreement is not revoked by Ludwig pursuant to Section 22
      below, all currently outstanding stock option grants to Ludwig will
      become fully vested and exercisable in accordance with and subject to
      their terms.

                  SECTION 6 -- UNKNOWN CLAIMS BY LUDWIG.

                  Ludwig expressly acknowledges that this Agreement is intended
to include in its effect, without limitation, all Claims that he does not know
of or suspect to exist in his favor at the time he signs this Agreement (or, of
applicable as at the Separation Date), and that this Agreement contemplates the
release of all such Claims.

                  SECTION 7 -- NO FILINGS BY LUDWIG/COVENANT NOT TO SUE.

                  Ludwig represents and agrees that he has not filed or caused
to be filed, on his own behalf, directly or indirectly, any complaints, charges,
applications, claims or grievances against any of the API Releasees with any
local state or federal agency, court, self-regulatory organization, or any other
public, quasi-public or private agency, organization, or entity, and that he
will not do so at any time, based on any act, omission, event, fact, or other
thing as to which he has given a release hereunder. Ludwig further agrees that
if any such agency, court, organization, or other entity assumes jurisdiction of
any such complaint, charge, application, claim, or grievance against any of the
API Releasees, on behalf of or with respect to Ludwig, he will request such
agency, court, organization, or other entity to withdraw from and dismiss the
matter with prejudice. This Section, however, shall not prohibit Ludwig from
filing or prosecuting a charge with any administrative agency as long as Ludwig
does not seek any damages or any other relief or remedy for himself.

                  SECTION 8 -- COMPLETE RELEASE BY API.

                  As a material inducement to Ludwig to enter into this
Agreement, API irrevocably and unconditionally releases and forever discharges
Ludwig from any and all "API Claims."

                  The term "API Claims" includes all charges, claims,
complaints, liabilities, obligations, promises, agreements, controversies,
damages, actions, causes of action, suits, rights, demands, costs, losses,
debts, and expenses (including attorneys' fees and costs actually incurred) or
similar rights of any nature whatsoever, known or unknown, which API now has or
claims to have, or which API at any time heretofore had or claimed to have, or
which API at any time hereafter may have or claim to have against Ludwig,
arising out of or related to any act, omission, event, fact or other thing which
existed or occurred (i) on or prior to the date API signed this Agreement, or
(ii) in the event but only in the event that Ludwig accepts any payment under
Section 3 hereof, on or prior to the Separation Date.

                  SECTION 9 -- UNKNOWN CLAIMS BY API.

                  API expressly acknowledges that this Agreement is intended to
include in its effect, without limitation, all API Claims as to which it has
given a release hereunder, and that this Agreement contemplates the release of
all such API Claims.

                  SECTION 10 -- CONFIDENTIAL INFORMATION.

                  (a)               Ludwig represents and agrees that in the
course of employment with API, he acquired confidential information and trade
secrets concerning API's and the other API Releasees' operations, future plans,
customer lists or other information, their methods of doing business, financial
information, ideas, processes and formulae, trade secrets, and other privileged,
confidential, and proprietary information ("Confidential Information"). In
addition, Ludwig specifically agrees that Confidential Information includes all
information or data, in writing or otherwise, or learned by Ludwig orally, by
observation or other sensory detection, relating to any product, product design,
service, research, development, formula, process, method of distribution or
delivery, know-how, contract term, customer pricing, supplier list or price,
business strategy, compensation, plan or practice, operating records, software,
technology, sales data, information or other records, lists or documents used by
API or API Releasees in operating their businesses or otherwise.

                  (b)               Ludwig represents and agrees that disclosure
of any Confidential Information would be extremely damaging to API or other API
Releasees if disclosed to a competitor or made available to any other person or
corporation. Ludwig represents and agrees that such Confidential Information has
been divulged to Ludwig in confidence and represents and agrees that he will
keep such Confidential Information secret and

                                                                     ---------

confidential and not disclose it before it becomes publicly available through no
fault of his own.

                  (c)               Ludwig agrees that he will not, for a period
of two (2) years after his separation from API (the "Restricted Period"),
directly or indirectly solicit, induce, encourage or attempt to influence any
client, customer, salesperson or supplier of API to cease to do business with
API. Ludwig further agrees that he shall not utilize for any such purposes any
names and addresses of customers or clients of API or any data on or relating to
past, present or prospective (at the time of his separation from API) customers
or clients of API.

                  (d)               Ludwig further agrees that during the
Restricted Period he will not, directly or indirectly, solicit for employment or
other business relationship any person who is, or within the preceding 12 months
was, an API or other API Releasee officer, manager, employee, or consultant.

                  (c)               In view of the nature of Ludwig's employment
and the Confidential Information that Ludwig has received during the course of
his employment, Ludwig likewise agrees that API and the other API Releasees
would be harmed irreparably by any violation, or threatened violation, of this
Section 10 and that, therefore, API and the other API Releasees shall be
entitled to an injunction prohibiting Ludwig from any violation or threatened
violation of this Agreement. The undertakings set forth in this Section 10 shall
survive the termination of other arrangements contained in this Agreement.

                  SECTION 11 -- CONFIDENTIALITY AND NONDISPARAGEMENT BY LUDWIG.

                  (a)               Ludwig represents and agrees that he has
kept and will keep any information concerning the circumstances or allegations
giving rise to Ludwig's Claims (if any) released herein to any person or entity
other than his tax advisor and attorneys ("Ludwig Confidants"), and that he only
will disclose such information to the Ludwig Confidants if such persons or
entities are informed of and agree to be bound by this confidentiality
provision. By way of illustration, Ludwig shall not disclose any information
concerning the circumstances or allegations giving rise to his Claims released
herein to anyone including, but not limited to, any representative of any print,
radio, or television media, to any past, present, or prospective employee or
customer of, or applicant for employment with, API or any of the other API
Releasees, to any counsel for any current or former employee or customer of API
or any of the other API Releasees, or to the public at large. This subsection
does not prohibit disclosures to the extent necessary legally to enforce this
Agreement or to the extent prohibited by law, nor does it prohibit disclosures
to the extent otherwise legally required (but only if Ludwig notifies API of a
such an obligation or request within 48 hours after he learns of it and allows
API to take all steps it deems to be appropriate to prevent or limit the
required disclosure).

                  (b)               Ludwig further agrees not to criticize,
denigrate, or disparage API or any other API Releasee.

                  (c)               In the event Ludwig is subpoenaed by a court
or other legal tribunal to testify or provide documents regarding his employment
with API, others' employment with API, API practices or procedures, or any other
subject matter involving, relating, or referring to API or any API Releasee, he
shall give notice to API within 48 hours by sending a copy of all such subpoenas
to the person at the address listed in Section 21 (or to such other person as
API may designate to Ludwig in writing) by priority overnight U.S. Postal
Service mail or UPS priority overnight delivery. To the extent permitted by law,
Ludwig agrees that he will take no action, direct or indirect, to encourage or
suggest the issuance of such subpoenas.

                  SECTION 12 -- FURTHER CONSEQUENCES OF LUDWIG'S VIOLATION OF
PROMISES.

                  Ludwig further agrees that API and the other API Releasees
would be irreparably harmed by any actual or threatened violation of Sections 10
or 11, and that to the extent not prohibited by law, API and the other API
Releasees shall be entitled to an injunction prohibiting Ludwig from committing
any such violation. Ludwig hereby consents to subject himself to personal
jurisdiction in the State of Michigan.

                  SECTION 13 -- OWNERSHIP CLAIMS BY LUDWIG.

                  Ludwig represents and agrees that he has not assigned or
transferred, or purported to assign or transfer, to any person or entity, any
Claims or any portion thereof, or interest therein.

                  SECTION 14 -- CONSULTATION WITH COUNSEL; FULL AND INDEPENDENT
KNOWLEDGE, UNDERSTANDING, AND CAPACITY.

                  Ludwig is advised to consult with an attorney of his choice
before signing this Agreement. Ludwig acknowledges and agrees that he has been
so advised; that Ludwig has fully discussed all aspects of this Agreement with
his counsel, to the full extent Ludwig so desired; that Ludwig has read
carefully and fully understands all of the provisions of this Agreement; that
Ludwig has taken as much time as he needs for full consideration of this
Agreement; that Ludwig is voluntarily entering into this Agreement; and that
Ludwig has the capacity to enter into this Agreement.

                  SECTION 15 -- NO REPRESENTATIONS.

                  Ludwig represents that in signing this Agreement, he does not
rely on nor has he relied on any representation or statement not specifically
set forth in this Agreement by any of the API Releasees or by any of the API
Releasees' agents,

returned to Ludwig. Existing Obligations Continue.

the lists of both parties, the parties shall strike names alternately from the
list of common names until only one remains. The party who did not initiate the
claim shall strike first. If no common name exists on the lists of both parties,
JAMS shall furnish an additional list and the process shall be repeated. If no
arbitrator has been selected after two lists have been distributed, then the
parties shall strike alternately from a third list, with the party initiating
the claim striking first, until only one name remains. That person shall be
designated as the arbitrator. Anytime a party is permitted under this Agreement
to make an arbitrator strike, such party must make the strike and communicate it
to the other party and JAMS within ten (10) calendar days of the date of the
transmittal communication relaying the arbitrators remaining for selection. In
the event a party does not make a timely strike, the other party may select the
arbitrator from the names remaining.

                  (b)               Costs of Arbitration: Each party shall pay
the fees of their respective attorneys, the expenses of their witnesses and any
other expenses connected with the arbitration, but all other costs of this
arbitration, including the fees of the arbitrator, cost of any record or
transcript of the arbitration, administrative fees and other fees and costs,
shall be paid in equal shared by Ludwig and API. The party losing the
arbitration shall reimburse the party who prevailed for all expenses the
prevailing party paid pursuant to the preceding sentence and for all reasonable
attorneys' fees (as determined by the Arbitrator) incurred by the prevailing
party in connection with the arbitration proceeding.

                  (c)               Exclusive Remedy: Arbitration in this manner
shall be the exclusive remedy for any Arbitrable Dispute. The arbitrator's
decision or award shall be fully enforceable and subject to an entry of judgment
by a court of competent jurisdiction. Should Ludwig or API attempt to resolve an
Arbitrable Dispute by any method other than arbitration pursuant to this
Paragraph, the responding party shall be entitled to recover from the initiating
party all damages, expenses and attorneys' fees incurred as a result and the
responding party shall be entitled to the return of any payments that party made
under this Agreement.

                  SECTION 20 -- FURTHER NECESSARY ACTIONS.


                  Ludwig agrees, without further consideration, to execute or
cause to be executed, and to deliver to API, any other documents and to take any
other action as may be necessary to more effectively consummate the subject
matter of this Agreement, including but not limited to appropriate resignations
from his positions with API.
