                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               December 26, 1999
                                   (Unaudited)

NOTE A - BASIS OF PRESENTATION

The accompanying  unaudited consolidated financial statements have been prepared
in  accordance  with  generally  accepted  accounting   principles  for  interim
financial  information and with the  instructions to Form 10-Q and Article 10 of
Regulation  S-X.  Accordingly,  they do not include all of the  information  and
notes  required  by  generally  accepted  accounting   principles  for  complete
financial statements. In the opinion of management,  all adjustments (consisting
of normal recurring  adjustments)  necessary for a fair  presentation  have been
included.  Operating  results for the nine month period ended December 26, 1999,
are not  necessarily  indicative  of the results  that may be  expected  for the
fiscal  year  ending  March 26,  2000.  For  further  information,  refer to the
consolidated  financial  statements  and notes thereto  included in the Advanced
Photonix,  Inc.  (together with its subsidiary,  the "Company") Annual Report on
Form 10-K for the fiscal year ended March 28, 1999.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Net Income (Loss) Per Share: Net loss per share is based on the weighted average
number of common and common equivalent shares outstanding. Net income (loss) per
share  calculations  are in accordance  with  Statement of Financial  Accounting
Standards  ("SFAS")  No. 128,  "Earnings  per Share".  Accordingly,  "basic" net
income  (loss)  per share is  computed  by  dividing  net  income  (loss) by the
weighted average number of shares outstanding for the year. "Diluted" net income
(loss) per share has not been  presented as the impact is either not material or
anti-dilutive.

Inventories:  Inventories consist of the following:

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

RESULTS OF OPERATIONS
- ---------------------
NET SALES

The  Company's  net sales for the third  quarter ("Q3 00") and nine month period
("YTD  00")  ended  December  26,  1999,  were $1.3  million  and $4.5  million,
respectively.  Net sales for the Q3 00 and YTD 00 period  were down 28% and 23%,
respectively,  when compared to $1.9 million and $5.8 million in the  comparable
periods of the prior year ("Q3 99" and "YTD 99").  The decrease in net sales was
primarily due to lower volume in military aerospace products, which decreased by
approximately  65%  in Q3 00,  and  by 58%  for  YTD  00  when  compared  to the
comparable periods in the prior year. The Company completed deliveries on orders
related to a large  military  program during the second half of fiscal 1999. New
purchase  orders under this  military  program  totaling more than $400,000 have
been booked and an additional order in excess of $500,000 is anticipated  during
Q4 00. Deliveries under these new orders are expected to resume during Q4 00. In
addition,  orders on another  military  program  totaling  $500,000  were booked
during Q4 for  deliveries  during Q4 00 and Q1 of fiscal  2001.  During  YTD 00,
shipments of Large Area Avalanche  Photodiode  (LAAPD) products (included in net
sales) were 2% higher  than the same period in the prior year.  While YTD 00 net
sales  from  these  products  represented  7% of total net  sales,  the  Company
anticipates  increasing  volume from sales of LAAPD products as markets begin to
implement this "enabling" technology.

COST OF SALES

Cost of sales  decreased by $287,000  (26%)  during Q3 00 and by $520,000  (15%)
during YTD 00  compared to Q3 99 and YTD 99,  respectively.  The  decreases  are
primarily attributable to lower product shipments. Cost of sales as a percent of
net sales  increased by 2 percentage  points in Q3 00 compared to Q3 99 and by 6
percentage  points  in YTD 00  compared  to YTD 99 due to a number  of  factors,
including  inefficiencies  associated with lower volume,  lower margins stemming
from variability in product mix, and decreased sales from engineering design.

OPERATING COSTS & EXPENSES

Research  and  development  costs for the Q3 00 and YTD 00 period were higher by
39% and 72%,  respectively,  when  compared  to  $146,000  and  $351,000  in the
comparable periods of the prior year. The increase in R&D costs is primarily due
to two factors: a.) higher overhead rates due to lower overall volume and b.) an
increase in internal R&D efforts as the Company focuses on improving its current
line of LAAPD products as well as expanding into new derivatives of the patented
technology.  The Company is  developing an Extreme Ultra Violet LAAPD capable of
detecting low light levels well below 200 nm. In addition, the Company continues
the development of a new generation  two-dimensional LAAPD Array. R&D costs have
varied significantly in the past, and may continue to do so, due to the level of
activity  associated  with  development  contracts  as  well as the  number  and
complexity of new process and product development projects, the qualification of
new process developments and customer evaluation and acceptance of new products.

                                       8


Marketing  and sales  expenses  decreased by $26,000  (11%) to $211,000 in Q3 00
compared  to Q3 99 and by $48,000  (6%) to $723,000 in YTD 00 compared to YTD 99
primarily  due to a decrease  in  commissions  paid.  The Company  believes  its
marketing  and sales  expenses  will  increase  in the near term as the  Company
pursues its plan of adding  additional  sales  personnel,  increased  trade show
attendance and substantial print media advertising.

General and administrative expenses decreased by $31,000 (12%) to $222,000 in Q3
00  compared  to Q3 99 and  increased  by $80,000  (10%) to  $904,000  in YTD 00
compared to YTD 99 primarily due to severance costs associated with a management
change. General and administrative expenses before the impact of severance costs
decreased  by $100,000  (12%) in YTD 00 when  compared to the same period of the
prior year. These decreases were primarily due to manpower  cutbacks and general
efforts to reduce costs.

LIQUIDITY AND CAPITAL RESOURCES

At December 26, 1999, the Company had cash and cash equivalents of $2.1 million,
working capital of $3.7 million and an accumulated deficit of $17.9 million. The
Company's  cash,  cash  equivalents  and  short-term  investments  decreased  by
$458,000  during the nine months ended  December 26, 1999.  Cash of $334,000 was
used for operating activities (before cash provided by short-term  investments).
Cash of $124,000 was used for capital equipment, compared to $119,000 during the
comparable period of the prior year.

To enable the  Company to meet its  capital  commitment  needs,  the Company has
historically supplemented cash provided by operations with proceeds from private
and public sales of capital stock and borrowings.  These funds have been used to
grow the core business and finance the development and initial commercialization
of the  Company's  LAAPD  technology.  While the Company  believes  that initial
commercialization  has been  completed  and has  reduced  its  expenditures  for
research and development,  it continues  development of other derivatives of the
base technology.  The continued development of LAAPD derivative products as well
as revenue growth in the business may require additional funds.

The Company's  revolving line of credit  agreement with a bank for the lesser of
$1,000,000 or 75 percent of eligible  trade accounts  receivable,  as defined by
the agreement, expired on July 16, 1999. The Company does not foresee a need for
borrowing based upon current projections and,  therefore,  has elected to forego
the costs for  maintaining  the line at this time. The Company  believes that it
would be most efficient to establish a line when the situation warrants.

During the period from January 1, 2000 to February 7, 2000,  the Company's  cash
position has improved due to the exercise of stock options.  During that period,
a total of $1.3 million has been received for such exercises resulting in a cash
balance  of  approximately  $3.2  million at  February  7,  2000.  Total  shares
outstanding at February 7, 2000 was 11,605,839

The Company believes that the moderate rate of inflation over the past few years
has not had a significant impact on the Company's sales or operating results.

FORWARD LOOKING STATEMENTS

The information  contained herein includes  forward looking  statements that are
based on assumptions  that management  believes to be reasonable but are subject
to inherent  uncertainties  and risks including,  but not limited to, unforeseen
technological  obstacles  which  may  prevent  or slow  the  development  and/or
manufacture  of new  products,  limited  (or slower than  anticipated)  customer
acceptance  of new  products  which  have  been and are being  developed  by the
Company  (particularly  its  LAAPD  product  line),  the  availability  of other
competing  technologies  and a decline in the general demand for  optoelectronic
products.
