Exhibit 10.29

                               SECURITY AGREEMENT

     This SECURITY  AGREEMENT  ("Security  Agreement")  is made and entered into
this April 30, 2004 by and among Pivotal Research  Centers,  L.L.C.  ("Pivotal")
and PHC, Inc. ("PHC"), a Delaware  corporation  (Pivotal and PHC are jointly and
severally  referred to herein as the  "Companies")  and Louis  Kirby  ("Kirby"),
Carol Colombo  ("Colombo"),  and Anthony Bonacci  ("Bonacci" and,  together with
Colombo and Kirby, the "Creditors").

                                    RECITALS

     A. PHC has  delivered to Creditors  (i) a Secured  Promissory  Note of even
date herewith in the original  principal amount of $1,000,000 ("Note A"), (ii) a
Secured  Promissory Note of even date herewith in the original  principal amount
of  $500,000  ("Note  B") and,  (iii) a  Secured  Promissory  Note of even  date
herewith in the original principal amount of $1,000,000 ("Note C"). Note A, Note
B and Note C are  sometimes  referred to together as the "Notes." The Notes were
delivered  pursuant  to a  Membership  Purchase  Agreement  dated  of even  date
herewith (the "Purchase  Agreement")  between PHC,  Pivotal and the Creditors in
their capacity as members of Pivotal,  pursuant to which PHC acquired all of the
Membership  Interests of Pivotal. All capitalized terms not defined herein shall
have the meaning set forth in the Purchase Agreement. In the event of a conflict
between a defined  term in this  Agreement  and a defined  term in the  Purchase
Agreement, the meaning set forth in the Purchase Agreement shall govern.

     B. In order to secure the  payment  and  performance  of all of the Secured
Obligations  (as defined  below),  PHC has agreed that  payment of the Notes and
performance  of the other  Secured  Obligations  are to be secured by all of the
Assets of the Pivotal Business now existing or hereafter  acquired as well as by
PHC's ownership interest in Pivotal pursuant to that certain Pledge Agreement of
even date herewith executed by PHC as pledgor and the Creditors as pledgees (the
"Pledge Agreement").

                                    AGREEMENT

     NOW,  THEREFORE,  in consideration of the mutual promises contained herein,
and in partial  consideration for the Creditors to accept the Notes, the parties
agree as follows

     1. GRANT OF SECURITY  INTEREST.  To secure  payment and  performance of the
"Secured  Obligations"  (as herein  defined)  Creditors  shall have, and Pivotal
hereby grants to Creditors,  a security  interest in the Collateral  subject and
subordinate  only  to the  lien,  if  any,  created  to  secure  payment  of the
Acquisition  Financing  and the  Letter of Credit (as  defined  in the  Purchase
Agreement).

     2. DEFINITIONS.

"Secured  Obligations"  means all obligations of the Companies,  in each case as
their  respective  interests  may appear,  now or hereafter  existing  under the
Notes, the Pledge  Agreement and this Agreement (in each case including  without
limitation  interest  accruing  after  maturity of any  obligation and after the
filing of any petition in bankruptcy,  or the  commencement  of any  insolvency,
reorganization or like proceeding  relating to either of the Companies,  whether

                                    -- 84 --

or not a claim for post  filing or  post-petition  interest  is  allowed in such
proceeding),  and all other  obligations  of Companies to any of the  Creditors,
whether direct, indirect,  absolute or contingent,  due or to become due, or now
existing or hereafter incurred, which may arise out of or in connection with the
Notes, this Agreement, or the Pledge Agreement, (in each case as the same may be
amended  from time to time by mutual  written  agreement of the parties) and any
other  document  made,  delivered or given in connection  therewith or herewith,
whether on account of principal,  premium, interest,  reimbursement obligations,
fees, costs, expenses (including without limitation,  all fees and disbursements
of counsel) or otherwise.

"Collateral"  means all or any  portion of the assets  described  on  Schedule 1
hereto.

     3.  WARRANTIES.  PHC and Pivotal each  warrants  that,  except as otherwise
provided in the Purchase Agreement:  (a) each of the Companies has the authority
and has  obtained  all  approvals  and  consents  necessary to incur the Secured
Obligations and enter into this Agreement,  and there is no legal restriction or
agreement  affecting its right to grant a security  interest in the  Collateral;
(b) except for the Accounts  Receivable  (as defined in the Purchase  Agreement,
which definition refers to accounts  receivable existing or created prior to the
Closing  Date and in no way  limits  the  coverage  of this  Security  Agreement
relating to accounts receivable created subsequent to the Closing Date), Pivotal
is,  and will be,  the owner of the  Collateral,  free and  clear of all  liens,
encumbrances and claims  whatsoever except for liens securing the payment of the
Acquisition Financing and the Line of Credit; (c) except for Accounts Receivable
(as  defined in the  Purchase  Agreement,  which  definition  refers to accounts
receivable  existing or created  prior to the Closing  Date and in no way limits
the coverage of this Security Agreement relating to accounts  receivable created

covering any of the property of the type,  kind or class of the Collateral is or
will be on file in any public office without Creditors' consent.  PHC shall have
no liability for the failure of the foregoing  representation to be true if such
failure is caused by (i) the failure of Sellers, or any of them to have properly
transferred the Membership  Interests to PHC in accordance with the terms of the
Purchase  Agreement  or (ii) the breach of any  representation  or  warranty  of
Sellers under the Purchase Agreement.

     4.  AFFIRMATIVE  COVENANTS.  PHC and Pivotal each agrees to: (a) defend the
Collateral and its proceeds against the claims and demands of all third persons;

applicable laws, statutes and regulations as is necessary, to create,  preserve,
validate,  perfect, evidence and/or continue Creditors' security interest in the
Collateral,  and/or to enable  Creditors  to exercise or enforce its rights with
respect to such security  interest;  (h) supply  Creditors with any  information

demonstrate,  sell,  assign,  transfer  or  dispose of the  Collateral  or their
respective  rights therein,  except in the ordinary course of Pivotal's or PHC's
business,  except  as  otherwise  provided  in  Section  3.11  of  the  Purchase

negligence or intentional  misconduct;  or (d) the performance or nonperformance

out of acts or decisions of public authorities,  strikes, lockouts, riots, wars,
acts of God or other causes beyond the control of Creditors,  its correspondents
or agents; or (f) any act or failure to act of their correspondents or agents.

     8. EVENTS OF DEFAULT.

          (a)  Mandatory.  Any of the  following  shall  constitute an "Event of
               Default" under this  Agreement:  (i) any breach of, or failure of
               any party to perform,  any  provision  of this  Agreement  or the
               Notes, or the occurrence of any of the events  described in (a) -
               (e) below,  and the  failure  of such party to cure such  breach,
               non-performance or event within the applicable "Cure Period",  if
               any; (ii)  termination of an Executive by PHC without  Cause,  as
               defined  in  the  Employment   Agreements;   (iii)  an  Executive
               terminates  his  employment  for Good  Reason,  as defined in the
               Employment Agreements;  or (iv) Buyer breaches Section 3.5 of the
               Purchase Agreement concerning  maintenance of the Line of Credit.
               There  shall be no "Cure  Period"  under this  Agreement  for any
               breach or failure  to  perform  that is based in whole or in part
               upon a  failure  to pay  monies  when due under  the  Notes.  For
               purposes of this  Agreement,  the term "Cure Period" shall mean a
               period of time that  commences  upon the giving of written notice
               by a  non-defaulting  party to the defaulting  party(ies)  that a
               breach or failure to perform has  occurred,  or in the case of an
               event  described in items (a)- (e) below the  occurrence  of such
               event,  and  expires  ten (10)  Business  Days from the date such
               notice is given. An Event of Default  hereunder based on any Note
               or the Pledge  Agreement,  but not the  Employment  Agreements or
               other this  Agreement,  shall occur after the  expiration  of the
               applicable  cure  period,  if any,  set  forth in any Note or the
               Pledge  Agreement,  and no  additional  time to cure  under  this
               Agreement  shall be given or is intended to be given  hereby.  In
               the event of  conflicting  cure periods in any Note or the Pledge
               Agreement, the shortest cure period shall control.

          (b)  Optional.  At Creditors'  option,  an Event of Default  hereunder
               shall be  deemed  to  occur  upon the  following  events  and the
               expiration  of the Cure  Period  described  above:  (a) either of
               Companies (i) is  adjudicated a bankrupt,  or an order for relief

               entered  naming  either of Companies  as "Debtor",  (ii) fails to
               pay,  or  admits  in  writing  its  inability  to pay,  its debts
               generally as they become due,  (iii) makes an assignment  for the
               benefit of creditors,  (iv) applies for,  seeks,  consents to, or

               for it or any  substantial  part of its property,  (v) institutes
               any  proceeding  seeking  dissolution,  winding up,  liquidation,
               reorganization,  arrangement,  adjustment or composition of it or
               its debts under any law  relating to  bankruptcy,  insolvency  or
               reorganization or relief of debtors or fails to file an answer or
               other  pleading  denying  the  material  allegations  of any such
               proceeding  filed against it, (vi) takes any corporate  action to
               authorize  or  effect  any of the  foregoing,  or (vii)  fails to
               contest in good faith any  appointment  or  proceeding  described
               above;  (b) either of Companies  fails to pay and  discharge  any
               material  indebtedness  when and as due  (except in the case of a

               indebtedness  becomes  entitled to accelerate the stated maturity
               thereof  except  where  failure to do so does not have a Material


                                    -- 88 --

               Adverse Effect;  (c) either of Companies contests the validity or
               enforceability of any document executed in connection herewith or
               with  the  Secured  Obligations  or  denies  it has  any  further
               liability or  obligation  thereunder,  or fails to perform any of
               its obligations  hereunder;  (d) there occurs a sale, assignment,
               pledge, transfer, hypothecation, encumbrance or other disposition
               of the  Collateral  or  any  portion  thereof  (or  any  interest
               therein) other than (i) in the ordinary course of business,  (ii)
               a  disposition  of  obsolete  or  retired  property,  or (iii) as

               injury to, or any destruction, loss or decline in value or market
               price of, the  Collateral  other than in the  ordinary  course of
               business that is not covered by insurance.

     9. CREDITORS' REMEDIES.  Upon the occurrence and continuance of an Event of
Default,  Creditors  (and its  agents)  shall have the rights and  remedies of a
secured creditor,  and Companies shall have the rights and duties provided under
the Uniform Commercial Code in force in Arizona at the date of this Agreement or
as such Uniform Commercial Code may thereafter be amended, and Creditors may, at
their  election and in addition to all other rights,  powers and  privileges and
notwithstanding the cessation of the Companies'  liability,  which the Companies
waive (other than by payment in full of the Secured Obligations), to the fullest
extent permitted by law: (a) declare the Secured Obligations  immediately fixed,
due and payable, the same as if the Secured Obligations had become in default or
past due,  and  proceed to collect  the same;  (b) waive or remedy any  default,
without waiving it or any prior or subsequent default; (c) as appropriate,  take
immediate  possession  of the  Collateral,  without  notice  and with or without
resort to legal  process,  and for such purpose  Creditors  may,  subject to the
restrictions set forth under the Law including,  but not limited to, the Uniform
Commercial  Code as enacted by the state of Arizona  enter upon any  premises on
which the Collateral or any part thereof may be situated and remove it therefrom
or render the Collateral unusable and upon Creditors' demand, each Company shall
assemble the Collateral and make it available at a reasonably  convenient  place
designated by  Creditors;  (d) remove any and all  Collateral  from the state or
country  in which it may be held to any  other  state or  country,  and there be
dealt with by Creditors as provided in this  Agreement;  (e) transfer any voting
securities, if any, constituting all or any part of the Collateral into the name
of  Creditors  for the  purpose  of voting  said  securities  as  Creditors  may
determine in their sole discretion;  (f) at its option, retain the Collateral in
satisfaction  of the  Secured  Obligations  by  sending  written  notice of such
election to PHC; (g) lease all or any part of the  Collateral,  or sell,  assign
and  deliver  all or any  part of the  Collateral  at  public  or  private  sale
(regardless  whether the  Collateral  is present at the place of sale),  without
notice  or  advertisement,  and at any sale or  disposition  of the  Collateral,
Creditors  may bid and become a purchaser at any public  sale,  and may accept a
trade of property for all or a portion of the sale price;  (h) make or have made
any necessary repairs, the reasonable cost of which is to be charged to PHC; (i)
realize  upon  insurance  policies  with a  cash  surrender  value,  securities,
instruments  or  documents  that will be redeemed by the issuer upon  surrender,
without  notice to PHC;  and (j) apply the  Collateral,  or the  proceeds of any
disposition of Collateral,  towards the satisfaction of the Secured Obligations,
in any order that Creditors, in their sole discretion, choose. In the event of a
failure by PHC in so doing,  Creditors may obtain physical damage/loss insurance
(protecting Creditors only if it chooses), pay taxes, assessments,  liens, fees,
charges or  encumbrances,  and order and pay for  repairs  or spend any  amounts
necessary to maintain the Collateral in Companies'  exclusive  possession and in


                                    -- 89 --

good  condition  and repair,  and all amounts so expended  shall,  with interest
thereon at the highest rate contracted with respect to the Secured  Obligations,
constitute  part of the Secured  Obligations  and shall be  immediately  due and
payable.  No such act or expenditure by Creditors  shall relieve  Companies from
the  consequences  of such  default.  The  making  of any  such  payment  or the
performance of any obligation on behalf of either Company shall constitute prima
facie evidence of the necessity and the  reasonableness  therefor.  If notice to
either Company is required,  Creditors shall give written notice to PHC not less
than ten (10) Business  Days prior to the date of public sale of the  Collateral
or prior to the date after which private sale of the Collateral  will be made by
mailing such notice to PHC at the address designated in the Purchase  Agreement.
PHC shall continue to be liable to Creditors for any deficiency  remaining after
application  of the Collateral or proceeds  thereof to the Secured  Obligations,
together with interest  thereon at the rate  applicable upon a default under the
agreement or instrument  evidencing the Secured  Obligations,  and if no rate is
provided, then at 15% per annum.

     10. WAIVERS.  Companies each waive:  (a) any right to require  Creditors to
proceed against any person,  exhaust any Collateral,  or pursue any other remedy
in  Creditors'  power;  (b) any defense  arising by reason of any  disability or
other defense of Company,  or any other person,  or by reason of cessation  from
any cause whatsoever of the liability of Company,  or any other person;  (c) any
right to enforce or compel the enforcement of any remedy which Creditors now has
or may hereafter have against Companies, or either of them, or against any other
person;  (d) any benefit of and any right to  participate  in the  Collateral or
other  security  whatsoever  now or  hereafter  held by  Creditors;  and (e) the
provisions  of  Delaware  and  Arizona  Statutes,  if  applicable,  relating  to
sureties.  Until all of the Secured  Obligations  shall have been  satisfied and
paid in full, neither of Companies shall have any right of subrogation.

     11.  MISCELLANEOUS  AGREEMENTS.  Each Company agrees: (a) to give Creditors
prior written notice of any change of residence,  place of business or insurance
with  respect to the  Collateral;  (b) demands  for  additional  or  substituted
Collateral, and any other demands or notices may be given by telegram, telephone
or cable, or by mailing the same, postage prepaid, to Companies' addresses shown
below;  (c)  acceptance  by Creditors of any  performance  which does not comply
strictly  with the terms hereof shall not be deemed to be a waiver or bar of any
right of Creditors, nor a release of any of the Secured Obligations; (d) each of
Companies  is and shall remain  subject to the in  personam,  in rem and subject
matter  jurisdiction  of the  Courts of the State of  Arizona  for all  purposes
pertaining to this  instrument  and all documents  and  instruments  executed in
