SECTION 1 -- REGISTRANT'S BUSINESS AND OPERATIONS

ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On December 22, 2005, Autocam Corporation ("we", "our", or "us") entered into a
new second lien Term Loan and Guaranty Agreement ("second lien credit facility")
with a syndicate of lenders, Goldman Sachs Credit Partners L.P. as syndication
agent, lead arranger and sole book runner, and The Bank of New York as
administrative agent and collateral agent. On that date we also amended our
existing senior credit facility.

For more information about our second lien credit facility and the amendment to
our existing senior credit facility, see the disclosure under Item 2.03 of this
report, which is incorporated by reference into this Item 1.01.

ITEM 2.03. CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN
OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT.

SECOND LIEN CREDIT FACILITY

As discussed in Item 1.01 above, we have entered into a second lien credit
facility. A copy of the second lien credit facility is attached hereto as
Exhibit 10.1 and is incorporated herein by reference. The following is a summary
of the material terms and conditions of our second lien credit facility, and is
qualified in its entirety by reference to the second lien credit facility.

Borrower, Amount and Final Maturity. Our second lien credit facility provides
for a $60,000,000 term loan and a E12,668,918.92 term loan (U.S. dollar
equivalent of $15,000,000). Each term loan has a final maturity of 6 years. We
are the Borrower under the term loans, which were fully borrowed at the closing
on December 22, 2005.

Use of Proceeds. Proceeds of the new term loans were used by us to repay amounts
under our existing senior credit facility as follows: (i) $12,600,000 of term
loans borrowed by us, (ii) E22,727,848 of term loans borrowed by our French
subsidiary, Autocam France, SARL, and (iii) $29,000,000 of revolving loans
borrowed by us. The balance of the proceeds will be used to pay transaction
costs and interest due on our existing senior credit facility and for future
working capital and general corporate purposes.

Interest and Fees. The interest rates applicable to loans under our second lien
credit facility will be (i) in the case of our U.S. dollar-denominated term
loans, at our option equal to either (x), a base (prime) rate plus 7.50% per
annum or (y) an adjusted Eurodollar bank deposit rate plus 8.50% per annum; or
(ii) in the case of our euro-denominated term loans, an adjusted Euro bank
deposit rate plus 9.50% per annum. We may at our option, in lieu of payment of
interest in cash, pay up to 1.50% per annum of the interest by adding such
interest to the then outstanding principal amount of the term loans
(payment-in-kind).

We may select interest periods (other than for base loans) of one, two, three,
six and, if available to each applicable lender, nine or twelve months for our
term loans.

We have agreed to pay various fees with respect to our second lien credit
facility, including customary arrangement fees paid to Goldman Sachs Credit
Partners L.P. and a customary annual administrative agent fee payable to The
Bank of New York.

Prepayments. Our second lien credit facility requires mandatory prepayments,
subject to exceptions, of an amount equal to:

-    100% of the net cash proceeds from asset sales or other dispositions of
     property by us or our subsidiaries, including insurance proceeds or
     governmental takings, other than inventory sold or disposed of in the
     ordinary course of business, certain other transactions and net cash
     proceeds reinvested in assets used in our business;

-    50% of the net cash proceeds from the issuance of specified equity
     securities, provided that this percentage will be reduced to 25% if our
     "Leverage Ratio", as defined in our second lien credit facility, is less
     than 3.00:1.00;

-    100% of the net cash proceeds from the issuance of specified debt
     obligations by us or our subsidiaries; and

<PAGE>

-    75% of "Consolidated Excess Cash Flow", as defined in our second lien
     credit facility, provided that this percentage will be reduced to 50% if
     our "Leverage Ratio" is less than 3.00:1.00.

Mandatory prepayments (which are permitted to be waived by the lenders in
certain circumstances) will be applied first to repay our obligations under our
existing senior credit facility, and then remaining amounts, if any, to our U.S.
dollar term loans and our euro term loans under our second lien credit facility
on a pro rata basis.

We are permitted to voluntarily prepay loans under our second lien credit
facility on or after December 22, 2006, subject to the terms of our existing
senior credit facility. If we voluntarily prepay all or any portion of our
second lien credit facility, we are required to pay a prepayment premium (as a
percentage of the principal prepaid) as follows: on or after December 22, 2006,
but prior to December 22, 2007, 2.0%; and on or after December 22, 2007, but
prior to December 22, 2008, 1.0%. The term loans under our second lien credit
facility may be prepaid without a prepayment penalty from and after December 22,
2008.

Collateral and Guarantors. Indebtedness under our second lien credit facility is
guaranteed by our holding company (Titan Holdings, Inc.), our Netherlands
subsidiary, Autocam Europe, B.V., and each of our existing and subsequently
acquired or organized domestic and, to the extent no material adverse tax
consequence would result and permitted under local law, each of our foreign
subsidiaries.

Indebtedness under our second lien credit facility is secured by a second
priority lien on substantially all of our and the guarantors' tangible and
intangible assets, including personal property, real property, intercompany
indebtedness and capital stock owned by us and such guarantors, limited to 65%
of such capital stock in the case of certain foreign subsidiaries.

The liens to secure our second lien credit facility are subordinated to the
liens to secure our existing credit facility. The priority of, and certain other
matters relating to, the liens in the collateral under our second lien credit
facility and our existing senior credit facility is set out in an intercreditor
agreement.

Financial and Restrictive Covenants. Our second lien credit facility contains
minimum senior leverage ratios that vary during the term of the facility.

Our second lien credit facility also contains covenants that restrict our
ability to incur additional indebtedness, grant liens, make investments, loans,
guarantees or advances, make restricted junior payments, including dividends,
redemptions of capital stock and voluntary prepayments or repurchase of certain
other indebtedness, engage in mergers, acquisitions or sales of assets, enter
into sale and leaseback transactions or engage in certain transactions with
affiliates and otherwise restrict certain corporate activities. These are
substantially identical to (and in some respects more flexible than) the
covenants in our existing senior credit facility

Representations and Affirmative Covenants. Our second lien credit facility
contains customary representations, warranties and affirmative covenants.

Events of Defaults. Our second lien credit facility contains customary events of
default, which are substantially as set forth in our existing senior credit
facility but with materiality thresholds 15% higher than the corresponding
provisions in our existing senior credit facility, including:

-    failure to make payments when due;

-    defaults under other materials indebtedness;

-    non-compliance with covenants;

-    incorrectness of representations and warranties;

-    bankruptcy, insolvency or dissolution events;

-    material judgments;

-    certain events related to ERISA;

-    impairment of security interests in collateral or invalidity of guarantees;
     and

-    a "change of control," as defined in our second lien credit facility.

<PAGE>

There is a 60-day standstill period with respect to a cross default to our
existing senior credit facility.

AMENDMENTS TO EXISTING SENIOR CREDIT FACILITY

On December 22, 2005, we entered into the second amendment to the Guaranty and
Credit Agreement, dated as of June 21, 2004 (the "Amendment") with Goldman Sachs
Credit Partners L.P. and Citigroup Global Markets, Inc. as Joint Lead Arrangers,
Goldman Sachs Credit Partners L.P., as Syndication Agent, Citicorp North
America, Inc., as General Administrative Agent and Collateral Agent, Citibank
International PLC, as European Administrative Agent, and Bank One, NA, ING
Capital, LLC and National City Bank, as Documentation Agents.

A copy of the Amendment is attached hereto as Exhibit 10.4 and is incorporated
herein by reference. The following is a summary of the material terms and
conditions of the Amendment, and is qualified in its entirety by reference to
the Amendment.

Pursuant to the Amendment, effective December 22, 2005, we amended our existing
senior credit facility to permit us to incur the second lien term loans
discussed above, to replace interest coverage, leverage and senior leverage
ratio covenants with maximum first lien leverage and revised senior leverage
ratio covenants, to amend the consolidated capital expenditures covenant and to
make other modifications.

We also permanently reduced the committed amount of our
multi-currency-denominated revolving credit facility to $28,880,000 and we
permanently reduced the committed amount of Autocam France, SARL's
euro-denominated revolving credit facility to E9,296,800.

The interest rate margins on our existing senior credit facility have changed.
The interest rate margin applicable to the U.S. Term Loans (with a Eurocurrency
rate) is 3.50% and the interest rate margin applicable to our Euro Term Loans is
4.00%, in each case from December 22, 2005 until the later of the first
anniversary of the effective date of the first amendment and the date we
demonstrate a "Leverage Ratio," as defined in our existing senior credit
facility, of less than or equal to 4.50:1.00. Thereafter, the applicable
interest rate margin is determined by reference to the Leverage Ratio in effect
from time to time as set forth below:

<TABLE>

--------------     --------------------------------------   ---------------------
<S>                <C>                                      <C>

     < 3.00:1.00                    3.00%                           3.50%
</TABLE>

If, at any time our "First Lien Leverage Ratio" as defined in our existing
senior credit facility exceeds 2.25:1.00, the applicable margins shown above
shall be increased by 0.25%, and if our First Lien Leverage Ratio exceeds
2.75:1.00, the applicable margins shown above shall be increased by an
additional 0.25%.

The interest rate margin applicable to swing line loans and other loans that are
base rate loans is an amount equal to the margin applicable to Eurocurrency rate
loans at that time, minus 1.00% per annum.

After giving effect to the prepayments made from the proceeds of the term loans
under our second lien credit facility, no amortization of the term loans under
our existing credit facility is required through the quarter ending June 30,
2008, and thereafter required amortization is as follows:
