                                                            Certificate No. ____
                                                    Dated as of October 19, 2004

     Reference is made to that certain Revolving Credit,  Term Loan and Security
Agreement dated as of the date hereof (as amended, supplemented or modified from
time to time, the "Loan Agreement"), among PHC, INC. a Massachusetts corporation
(the "Company") and certain of its subsidiaries,  NORTH POINT PIONEER,  INC. and
CAPITALSOURCE  FINANCE  LLC (the  "Lender"),  an  affiliate  of CS EQUITY LLC, a
Delaware  limited  liability  company  ("CapitalSource"),  and to the other Loan
Documents,  pursuant to which the Lender has agreed to make certain loans to the
Borrowers  (the  "Loans").  This  Warrant  is issued at  Closing  under the Loan
Agreement  and  means  and  shall  include  any  and  all  warrants   issued  in
substitution  for and/or in replacement of this Warrant.  The obligations of the
Lender  to  execute  and  deliver  the  Loan  Documents  and to  consummate  the
transactions  thereunder are conditioned on, among other things, the issuance of
this Warrant to CapitalSource,  and the Company has agreed to issue this Warrant
to  CapitalSource  in order to  induce  such  affiliate  to enter  into the Loan
Documents and to make the Loans.

     Capitalized  terms used in this Warrant and not  elsewhere  defined  herein
shall have the  meanings  set forth in Schedule 1 to this Warrant or in the Loan
Agreement (if not defined herein).

1.   Grant.  In  consideration  of the foregoing and other value  received,  the
     Company  hereby grants to  CapitalSource  and/or its assigns or transferees
     (collectively,  the "Holder"), at the exercise price set forth in Section 3
     below,  the right to purchase up to 250,000  shares of Class A Common Stock
     (or  other  security  issued in  accordance  with  Section  8)  subject  to
     adjustment from time to time (the "Warrant Shares").


                                    -- 5 --

2.   Exercise Period.  The right to exercise this Warrant,  in whole or in part,
     begins on the date  that  pursuant  to  Section 9 below,  the  Company  has
     informed the Holder that the Company has amended its Charter to provide for
     adequate  authorized  Warrant  Shares and has reserved those Warrant Shares
     for issuance  under this Warrant,  and expires on the tenth  anniversary of
     the date hereof (such date, the "Expiration Date").

3.   Exercise Price.  The exercise price of this Warrant is $1.15 per share (the
     "Exercise Price").

4.   Anti-Dilution Adjustment.

     (a)  Dilutive  Transactions.  Each time the Company  enters into a Dilutive
Transaction,  the number of Warrant Shares issuable hereunder shall be increased
to the number  determined by performing the following  calculation  and rounding
the resulting  number to the nearest whole share:  divide:  (i) the Non-Dilutive
Price of a Warrant  Share  then in effect  multiplied  by the  number of Warrant
Shares then issuable hereunder, by (ii) the Weighted Average Per Share Value.

     (b) Readjustment.  If any option, right or right to convert or exchange any
Common Stock Equivalent issued in connection with a Dilutive Transaction expires
without having been exercised  prior to the exercise by the Holder of its rights
hereunder,  the number of Warrant Shares then issuable hereunder shall forthwith
be  readjusted to such lesser number as would have been issuable had the option,
right or Common Stock Equivalent never been issued.

     (c)  Adjustment of Exercise  Price.  Upon each  adjustment of the number of
Warrant  Shares as provided in  Subsection  4(a),  the  Exercise  Price shall be
adjusted to the dollar figure  (calculated  to the nearest  hundredth of a cent)
obtained by multiplying the Exercise Price in effect  immediately  prior to such
adjustment  by  the  number  of  Warrant  Shares  purchasable   pursuant  hereto
immediately  prior to such  adjustment  and dividing the product  thereof by the
number of Warrant Shares purchasable pursuant hereto immediately  following such
adjustment.

5.   Other Adjustments.

     (a) Adjustment for Change in Class A Common Stock.  If the Company (i) pays
a dividend or makes a distribution  on its Class A Common Stock in shares of its
Common Stock, (ii) subdivides,  splits or reclassifies its outstanding shares of
Class A Common  Stock into a greater  number of  shares,  or (iii)  combines  or
reclassifies  its  outstanding  shares of Common Stock into a smaller  number of
shares (each,  an "Adjustment  Event"),  the number of Warrant  Shares  issuable
hereunder immediately prior to such action shall be proportionately  adjusted so
that the Holder will receive,  upon exercise,  the aggregate  number and kind of
shares of capital  stock of the  Company  which it would have owned  immediately
following  such  action  if the  Holder  had  exercised  this  Warrant  in  full
immediately  prior  to  such  Adjustment  Event.  The  adjustment  shall  become
effective  immediately  after  the  record  date in the  case of a  dividend  or
distribution

                                    -- 6 --


and  immediately  after  the  effective  date  in  the  case  of a  subdivision,
combination  or  reclassification.  The  adjustment  shall be made  successively
whenever any Adjustment Event occurs.

     (b) Adjustment for Reorganization. Subject to Section 11.9, if there occurs
any Change of Control,  there shall thereafter be deliverable,  upon exercise of
this Warrant (in lieu of the number of Warrant Shares  theretofore  deliverable)
the number of shares of stock or other  securities or property to which a holder
of the number of shares of Class A Common Stock that would  otherwise  have been
deliverable  upon exercise of this Warrant in full would have been entitled upon
such Change of Control if such Warrant had been  exercised  in full  immediately
prior to such Change of Control.

     (c)  Adjustment of Exercise  Price.  Upon each  adjustment of the number of
Warrant  Shares  issuable  hereunder as provided in this Section 5, the Exercise
Price shall also be equitably and proportionately adjusted.

     (d)  Certificate  as to  Adjustments.  In each  case of any  adjustment  or
readjustment in the number of shares, securities or other property issuable upon
exercise  of this  Warrant  and/or in the  Exercise  Price,  the  Company at its
expense will promptly provide written notice to the Holder stating the number of
shares of Class A Common Stock, other securities or other property then issuable
upon  exercise of this  Warrant  and the  applicable  Exercise  Price after such
adjustment, showing how such amounts were calculated.

6.   Participation in Dividends,  Distributions,  Repurchases or Redemptions. If
     the Company declares any dividend or makes any distribution,  in each case,
     that is not in shares of Class A Common Stock,  or  repurchases  or redeems
     any of its capital stock (except forfeitures by holders, and/or repurchases
     by the Company,  of any shares of Class A Common Stock or options  pursuant
     to any employment  agreements with executives of the Company or pursuant to
     any equity  incentive  plan in  existence  on the date hereof that has been
     approved by the  stockholders  of the Company and qualifies as an incentive
     plan under the  Internal  Revenue Code of 1986,  as amended  (collectively,
     "Permitted  Redemptions")),  the Company  will pay the Holder the  declared
     dividend,  or offer to include the Holder in such distribution,  repurchase
     or  redemption,  as if the  Holder  had  exercised  this  Warrant  in  full
     immediately prior to such event or any record date with respect thereto. If
     the Holder  elects to  participate  in a  repurchase  or  redemption,  this
     Warrant shall be modified (as of the date of such event) so that the Holder
     shall be entitled to receive,  upon exercise,  the number of Warrant Shares
     issuable   hereunder  less  the  number  of  Warrant  Shares   redeemed  or
     repurchased.

7.   Prior Notice as to Certain Events.

     (a) Dividends, Distributions,  Subscription Rights. If the Company (i) pays
any dividend,  or makes any  distribution,  or repurchases or redeems any of its
capital  stock  (except  Permitted  Redemptions),  (ii) offers any  subscription
rights to the holders of its capital stock to purchase any additional  shares of
stock of any class or any other  rights,  or (iii)  authorizes  the  issuance of
shares of Common  Stock or Common Stock  Equivalents,  then at least 15 Business
Days prior to the action or record date for such  action,  the Company will send
written  notice to the Holder of the dates on which (A) the  Company  will close
its books or take a
                                    -- 7 --

record for such  action,  (B) such  action  will  occur,  and (C) the holders of
capital stock of record will participate in such action.

     (b) Change of Control. If the Company (i) enters into any Change of Control
or  reclassification  of its  capital  stock or equity  securities,  (ii) is the
subject of a voluntary or involuntary dissolution,  liquidation or winding up or
(iii)  receives  a notice  from any holder of its  equity  securities  that such
holder  desires to exercise its right to "put" or sell such  securities  back to
the Company or to have such  securities  redeemed or repurchased by the Company,
then at least 15 Business Days prior to such action or transaction,  the Company
will send  written  notice to the  Holder of the dates on which (A) the  Company
will  close its books or take a record for such  action,  (B) such  action  will
occur,  and (C) if  applicable,  the  holders  of  capital  stock of record  may
exchange their capital stock for securities or other property  deliverable  upon
such action.

8.   Intentionally Omitted

9.   Reservation of Class A Common Stock; Par Value. The Company shall set forth
     a proposal to amend the Company's  Certificate of Incorporation to increase
     the number of authorized  shares of the Company's Class A Common Stock such
     that it will have upon the  exercise  of this  Warrant  such  number of its
     authorized  but  unissued  shares  of  Class  A  Common  Stock  as  will be
     sufficient to permit the exercise in full of this  Warrant,  at each annual
     meeting of the Company's  stockholders  until such proposal is adopted (and
     at all times thereafter if there are  insufficient  authorized but unissued
     shares  of Class A Common  Stock to  permit  the  exercise  in full of this
     Warrant) or until the Expiration Date has occurred.  Promptly following the
     approval of such proposal by the Company's  stockholders,  the Company will
     cause  the  Company's   Certificate  of  Incorporation  to  be  amended  in
     accordance  with such  approved  proposal and shall provide the Holder with
     prompt written notice thereof.

Upon issuance, each of the Warrant Shares will be validly issued, fully paid and
nonassessable,  free and  clear of all  preemptive  or  similar  rights,  liens,
security  interests,  charges and other encumbrances and/or restrictions on sale
or otherwise. Without limiting the generality of the foregoing, the Company will
(i) not permit the par value,  if any, of its Class A Common Stock to exceed the
then effective  Exercise  Price,  and in  furtherance  of the  foregoing,  shall
promptly cause the Certificate of  Incorporation of the Company to be amended to
reduce  the par  value of the  Class A Common  Stock  if the  Exercise  Price is
reduced below the current par value,  and (ii) not amend or modify any provision
of the Certificate of  Incorporation of the Company or by-laws of the Company in
any manner that would  adversely  affect in any way the powers,  preferences  or
rights of the Class A Common Stock or which would adversely affect the rights of
the Holder.

10.  No Voting Rights; Limitations of Liability. Prior to exercise, this Warrant
     will not  entitle  the  Holder to any  voting  rights or other  rights as a
     stockholder  of the  Company  not  granted  herein.  No  provision  of this
     Warrant,  in the  absence of  affirmative  action by the Holder to exercise
     this  Warrant,  and  no  enumeration  in  this  Warrant  of the  rights  or
     privileges  of the Holder,  will give rise to any  liability of such Holder
     for the Exercise Price.

                                    -- 8 --

11.  Registration Rights.

11.1 Effective Date. The rights of each Holder that holds Registrable Securities
     under this Section 11 are  effective as of the date hereof and shall remain
     in full force and effect  for so long as the Holder  continues  to hold any
     Registrable  Securities  and  regardless of any transfer of this Warrant or
     its termination upon its exercise in full.

11.2 Intentionally Omitted.

11.3 Piggyback Registrations.

     (1) RIGHT TO  PIGGYBACK.  Whenever the Company  proposes to register any of
its  securities  under the Securities Act (other than pursuant to a registration
on Form S-8 or Form S-4 or any successor forms, a registration  covering only an
employee  benefit  plan  (as  defined  in Rule 405 of the  Securities  Act) or a
registration  covering  only  securities  proposed to be issued in exchange  for
securities or assets of another  corporation)  and the  registration  form to be
used may be used for the  registration  of Registrable  Securities (a "Piggyback
Registration"),  the Company will give prompt  written  notice to all holders of
Registrable  Securities  and  (subject to  subsections  (2) and (3) below) shall
include in such  registration  all Registrable  Securities with respect to which
the Company has  received  written  requests  for  inclusion  therein  within 15
Business  Days after the day on which the Company's  notice is deemed  delivered
under the terms  hereof.  The  foregoing  right  shall not apply to the  Company
registration  of shares of its Class A Common  Stock on Form S-3 filed  with the
SEC prior to the date hereof and awaiting SEC effectiveness.

     (2) PRIORITY ON INITIAL  REGISTRATION.  If a Piggyback  Registration  is an
underwritten  registration of shares being sold by the Company, and the managing
underwriter(s) advise the Company in writing that in their opinion the number of
securities  requested  to be  included in such  registration  exceeds the number
which can be sold in such offering without adversely affecting the marketability
of the offering, the Company will include in such registration:

     (i) first, the securities the Company proposes to sell;

     (ii)  second,  to the extent a number of  additional  securities  are to be
included  in  the  registration,  the  Registrable  Securities  requested  to be
included in such registration; and

     (iii)  third,  to the extent a number of  additional  securities  are to be
included in the registration,  all other securities  requested to be included in
such  registration  pursuant  to the  exercise of other  piggyback  registration
rights granted by the Company.

                                    -- 9 --

     (3) PRIORITY ON SUBSEQUENT REGISTRATION.  If a Piggyback Registration is an
underwritten  registration other than a registration of shares being sold by the
Company, and the managing  underwriter(s)  advise the Company in writing that in
their  opinion  the  number  of  securities  requested  to be  included  in such
registration  exceeds  the  number  which can be sold in such  offering  without
adversely affecting the marketability of the offering,  the Company will include
in such registration:

     (i)  first,  Registrable  Securities  requested  to  be  included  in  such
registration;

     (ii)  second,  to the extent a number of  additional  securities  are to be
included in the registration, the securities the Company proposes to sell; and

     (iii)  third,  to the extent a number of  additional  securities  are to be
included in the registration,  all other securities  requested to be included in
such  registration  pursuant  to the  exercise of other  piggyback  registration
rights granted by the Company.

11.4 Intentionally Omitted.

11.5 Registration  Procedures.  Whenever the holders of  Registrable  Securities
     have requested that any  Registrable  Securities be registered  pursuant to
     this Agreement,  the Company will use its best reasonable efforts to effect
     the registration and the sale of such Registrable  Securities in accordance
     with the intended method of disposition therefor, and pursuant thereto, the
     Company will, as expeditiously as possible, do all of the following:

     (1)  REGISTRATION STATEMENT.  Prepare and file with the U.S. Securities and
          Exchange Commission (the "SEC") a registration  statement with respect
          to such Registrable  Securities and use its best reasonable efforts to
          cause such registration  statement to become effective  (provided that
          before filing a registration statement or prospectus or any amendments
          or  supplements  thereto,  the  Company  will  furnish to the  counsel
          selected by the holders of a majority  of the  Registrable  Securities
          covered by such  registration  statement  copies of all such documents
          proposed to be filed,  which  documents  will be subject to the review
          and approval of such counsel) and use its best  reasonable  efforts to
          avoid the  issuance of (or if issued,  obtain the  withdrawal  of) any
          order suspending the effectiveness of a registration statement, or the
          lifting of any  suspension of the  qualification  (or  exemption  from
          qualification)  of any of the  Registrable  Securities for sale in any
          jurisdiction as soon as possible;

                                    -- 10 --

     (2)  AMENDMENTS  &  SUPPLEMENTS.   Prepare  and  file  with  the  SEC  such
          amendments  and  supplements  to such  registration  statement and the
          prospectus  used in  connection  therewith as may be necessary to keep
          such registration statement effective for a period necessary to comply
          with  the  provisions  of  the  Securities  Act  with  respect  to the
          disposition of all securities  covered by such registration  statement
          during  such  period  in  accordance  with  the  intended  methods  of
          disposition  by the sellers  thereof,  which  period shall not be less
          than six months;

     (3)  FURNISH COPIES.  Furnish to each seller of Registrable Securities such
          number of copies of such  registration  statement,  each amendment and
          supplement  thereto,  the prospectus  included therein (including each
          preliminary  prospectus)  and such other  documents as such seller may
          reasonably  request  in order to  facilitate  the  disposition  of the
          Registrable Securities covered by such registration statement;

     (4)  BLUE-SKY  COMPLIANCE.  Use its best reasonable  efforts to register or
          qualify such  Registrable  Securities  under such other  securities or
          blue  sky  laws of such  United  States  jurisdictions  as any  seller
          reasonably requests and do any and all other acts and things which may
          be  reasonably  necessary  or  advisable  to  enable  such  seller  to
          consummate the  disposition in such  jurisdictions  of the Registrable
          Securities owned by such seller (provided that the Company will not be
          required to (i) qualify  generally to do business in any  jurisdiction
          where  it  would  not  otherwise  be  required  to  qualify  for  this
          subparagraph,   (ii)   subject   itself  to   taxation   in  any  such
          jurisdiction,  or (iii)  consent to general  service of process in any
          such  jurisdiction  other  than  with  respect  to  the  registration,
          qualification or exemption therefrom of the Registrable Securities);

     (5)  NOTIFICATIONS.  Notify each seller of such  Registrable  Securities at
          any time when a registration  statement  related  thereto is effective
          under the Securities Act, of the happening of any event as a result of
          which the prospectus included in such registration  statement contains
          an untrue  statement of a material fact or omits any fact necessary to
          make  the   statements   therein  not   misleading  in  light  of  the
          circumstances  then existing,  and, at the request of any such seller,
          the Company will prepare a supplement or amendment to such  prospectus
          so that, as thereafter delivered to the purchasers of such Registrable
          Securities,  such prospectus will not contain an untrue statement of a
          material  fact  or  omit to  state  any  fact  necessary  to make  the
          statements therein not misleading;

     (6)  LISTING. Use its best reasonable efforts to cause all such Registrable
          Securities  to be listed on any  nationally  recognized  United States
          trading market, if applicable, on which similar securities of the same
          class issued by the Company are then listed;

                                    -- 11 --

     (7)  TRANSFER AGENT; REGISTRAR.  Provide a transfer agent and registrar for
          all such  Registrable  Securities not later than the effective date of
          such registration statement;

     (8)  OMITTED.

     (9)  SUPPLY  INFORMATION.  Make  available for  inspection by any seller of
          Registrable Securities,  underwriter  participating in any disposition
          pursuant to such registration  statement and any attorney,  accountant
          or  other  agent  retained  by any such  seller  or  underwriter,  all
          financial  and  other  records,   pertinent  corporate  documents  and
          properties  of  the  Company,   and  cause  the  Company's   officers,
          directors,   employees  and  independent  accountants  to  supply  all
          information  reasonably  requested  by any such  seller,  underwriter,
          attorney,  accountant  or agent in connection  with such  registration
          statement; and

     (10) OBTAIN COLD  COMFORT  LETTER AND  OPINIONS  OF COUNSEL.  Obtain a cold
          comfort letter from the Company's  independent  public accountants and
          opinions of counsel from the  Company's  attorneys,  each in customary
          form and covering such matters as are customarily  given or covered by
          independent  public  accountants and attorneys,  as applicable,  in an
          underwritten public offering of securities, addressed to the sellers.

11.6 Registration Expenses. The Company shall bear and pay all expenses incurred
     in connection with any registration, filing or qualification of Registrable
     Securities with respect to the  registrations  pursuant to this Section 11,
     including,  without limitation, all registration,  filing and qualification
     fees,  printing and accounting  fees,  listing fees and expenses,  fees and
     expenses  of  compliance  with  securities  or  blue  sky  laws,  fees  and
     disbursements  of  counsel  for the  Company  and the  reasonable  fees and
     disbursements  of one counsel for the  sellers of  Registrable  Securities.
     Underwriting  discounts and commissions relating to Registrable  Securities
     will  be  borne  and  paid  ratably  by the  sellers  of  such  Registrable
     Securities.

11.7 Indemnification Provisions.

     (1) INDEMNITY OF HOLDERS OF REGISTRABLE  SECURITIES.  The Company agrees to
indemnify,   to  the  extent  permitted  by  law,  each  holder  of  Registrable
Securities,  its officers and  directors  and each Person who controls each such
holder  (within the meaning of the Securities  Act) against all losses,  claims,
damages,  liabilities  and  expenses  caused  by any  untrue or  alleged  untrue
statement of material fact contained in any registration  statement,  prospectus
or preliminary  prospectus or any amendment thereof or supplement thereto or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements  therein not misleading,  except insofar as the
same are caused by or contained in any  information  furnished in writing to the
Company or any underwriter by such  holder expressly  for use therein or by such

                                    -- 12 --

holder's  failure to deliver to the  Company  in  writing  the  information  and
affidavits required by subsection (2) of this Section 11.7 after the Company has
furnished  such holder with a  sufficient  number of copies of the  registration
statement or prospectus or any amendments or supplements thereto.

     (2) DISCLOSURE AND INDEMNIFICATION BY HOLDERS OF REGISTRABLE SECURITIES. In
connection with any registration statement in which a holder of such Registrable
Securities  is  participating,  each such holder will  furnish to the Company in
writing such information and affidavits  relating to disclosure  concerning such
holder  required  to be included in the  registration  statement  as the Company
reasonably  requests for use in connection with any such registration  statement
or prospectus  and, to the extent  permitted by law, will indemnify the Company,
its directors and officers and each person who controls the Company  (within the
meaning of the Securities Act) against any losses, claims, damages,  liabilities
and expenses  resulting from any untrue  statement of material fact contained in
the  registration  statement,   prospectus  or  preliminary  prospectus  or  any
amendment  thereof or  supplement  thereto or any  omission  of a material  fact
required to be stated  therein or necessary to make the  statements  therein not
misleading,  but only to the extent  that such untrue  statement  or omission is
contained  in any  information  or  affidavit  so  furnished  in writing by such
holder; provided, however, that the obligation to indemnify will be several, not
joint and several, among such holders; and provided,  further,  however that the
liability of each holder will be in  proportion to and limited to the net amount
received by such holder from the sale of Registrable Securities pursuant to such
registration statement.

     (3) NOTICE AND DEFENSE.  Any person entitled to  indemnification  hereunder
will: (i) give prompt written notice to the indemnifying party of any claim with
respect to which it seeks  indemnification,  and (ii)  unless in the  reasonable
opinion of such indemnified  party's counsel a conflict of interest between such
indemnified  and  indemnifying  parties  may exist with  respect to such  claim,
permit such indemnifying  party to assume the defense of such claim with counsel
reasonably  satisfactory  to the indemnified  party.  The failure to give timely
notice will not relieve the receiving party of any obligation  unless such delay
unduly  prejudices such party's ability to defend such claim. If such defense is
assumed,  the  indemnifying  party will not be subject to any  liability for any
settlement  or omission made by the  indemnified  party without its consent (but
such consent will not be  unreasonably  withheld) and an indemnified  party will
not be subject to any  liability  for any  settlement  or  omission  made by the
indemnifying   party   without  its  consent  (but  such  consent  will  not  be
unreasonably  withheld). An indemnifying party who is not entitled to, or elects
not to,  assume the defense of a claim will not be obligated to pay the fees and
expenses  of  more  than  one  counsel  for  all  parties  indemnified  by  such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any  indemnified  party  a  conflict  of  interest  may  exist  between  such
indemnified party and any other of such indemnified parties with respect to such
claim.

                                    -- 13 --

     (4)  CONTINUING  AND  SURVIVING  OBLIGATIONS;  RIGHT OF  CONTRIBUTION.  The
indemnification  provided  for under this  Warrant will remain in full force and
effect regardless of any  investigation  made by or on behalf of the indemnified
party or any officer,  director or controlling  person of such indemnified party
and will  survive  the  transfer  of  securities  after  the  completion  of any
offering. The Company also agrees to make such provisions, based on its relative
fault, for contribution to such party in the event the Company's indemnification
is unavailable for any reason. The relative fault of the Company and the selling
holder shall be  determined  by reference  to, among other  things,  whether the
untrue  statement or alleged untrue statement of a material fact or the omission
or alleged omission to state a material fact relates to information  supplied by
the Company or the selling holder and the parties'  relative intent,  knowledge,
access to  information  and  opportunity to correct or prevent such statement or
omission.

11.8 Rule 144  Requirements.  With a view to making  available  the  benefits of
     certain rules and  regulations  of the SEC which may at any time permit the
     sale of the Registrable Securities to the public without registration,  the
     Company agrees to:

     (1) make and keep public information available,  as defined for purposes of
Rule 144 under the Securities Act;

     (2) use its best reasonable efforts to file with the SEC in a timely manner
all  reports and other  documents  required of the Company to be filed under the
Securities  Act and  the  Securities  Exchange  Act of  1934,  as  amended  (the
"Exchange Act"); and

     (3)  furnish to any  holder of  Registrable  Securities,  upon  request,  a
written  statement  by the  Company  as to its  compliance  with  the  reporting
requirements  of Rule 144 under the Securities Act and of the Securities  Act, a
copy of the most recent annual or quarterly report of the Company and such other
reports and  documents of the Company as such holder may  reasonable  request to
avail  itself of any similar rule or  regulation  of the SEC allowing it to sell
any such securities without registration.

11.9 Mergers, Etc. The Company shall not, directly or indirectly, enter into any
     Change  of  Control  transaction  in which  the  Company  shall  not be the
     surviving  Company unless the proposed  surviving  Company shall,  prior to
     such transaction, agree in writing to assume the obligations of the Company
     under this Warrant,  including but not limited to those under Section 11 of
     this Warrant,  and for that purpose  references  hereunder to  "Registrable
     Securities"  shall be  deemed to be  references  to the  securities  that a
     Holder would be entitled to receive in exchange for Registrable  Securities
     under and/or in connection with any such  transaction;  provided,  however,
     that the  provisions  of this  Warrant  shall not apply in the event of any
     such  transaction in which the Company is not the surviving  Company if all
     Holders holding Registrable  Securities are entitled to receive in exchange
     for all of their Registrable Securities  consideration consisting solely of
     (i) cash, (ii) securities of the acquiring  Company that may be immediately

                                    -- 14 --

     sold to the public without  registration under the Securities Act, or (iii)
     securities of the acquiring  Company that the acquiring  Company has agreed
     to register,  and actually does register, for resale to the public pursuant
     to the Securities Act, provided such registration occurs  contemporaneously
     with consummation of the transaction.

11.10 Miscellaneous.  The Company  has not  granted  and will  not  grant to any
     Person the right to request the Company to register  any equity  securities
     of the Company,  or any  securities  convertible  or  exchangeable  into or
     exercisable for such securities or any other Common Stock Equivalents, that
     in any material manner are more favorable to such Person than those granted
     herein.

12.  Exercise  Procedure.  To exercise this Warrant,  the Holder must deliver to
     the principal  office of the Company  (prior to the  Expiration  Date) this
     Warrant,  the subscription  substantially in the form of Exhibit A attached
     hereto and the Exercise Price for the Warrant Shares being  purchased.  The
     Holder may deliver the Exercise Price by any of the following  methods,  at
     its option: (i) in legal tender, (ii) by bank cashier's or certified check,
     (iii) by wire transfer to an account designated by the Company,  or (iv) in
     accordance with Section 13. Upon exercise, the Company, at its sole expense
     (including the payment by the Company of any documentary,  stamp,  issue or
     transfer  taxes),  will issue and deliver to Holder,  within five  Business
     Days  after  the  date  on  which  the  Holder   exercises   this  Warrant,
     certificates  for  the  Warrant  Shares  purchased  upon  exercise  of this
     Warrant.  The Warrant Shares so purchased  shall be deemed issued,  and the
     Holder deemed the holder of record of such Warrant Shares,  as of 9:00 a.m.
     (New  York  City  time) on the  date on which  the  Holder  exercises  this
     Warrant.  The Company  shall pay any and all  documentary,  stamp or issue,
     transfer  or similar  taxes  payable in respect of the issue or delivery of
     the Warrant  Shares.  This Warrant may be exercised in whole or in part and
     in the event  this  Warrant  is  partially  exercised,  the  Company  shall
     forthwith  issue and  deliver to the Holder a new  Warrant of like tenor to
     purchase  that number of Warrant  Shares with respect to which such partial
     exercise did not apply.

13.  Cashless Exercise. In lieu of paying the applicable Exercise Price by legal
     tender, check, or wire transfer,  the Holder may elect to receive, upon any
     exercise  of this  Warrant,  that  number of  Warrant  Shares  equal to the
     quotient  obtained by  dividing:

                            [(A-B)(X)] by (A), where:

          A    = the Fair Market Value of a share of Class A Common Stock on the
               date of exercise;

          B    = the Exercise Price for a share of Class A Common Stock; and

          X    = the number of Warrant  Shares (equal to or less than the number
               of  Warrant  Shares  then  issuable  hereunder)  as to which this
               Warrant is being exercised.

                                    -- 15 --

14.  Sale of Warrant or Warrant Shares. Neither the issuance of this Warrant nor
     the  issuance of any of the Warrant  Shares upon  exercise of this  Warrant
     have been registered  under the Securities Act or the Exchange Act or under
     the securities  laws of any state.  The issuance of the Warrant Shares upon
     exercise of this Warrant shall be subject to compliance with all applicable
     federal and state  securities  laws.  Neither  this  Warrant nor any of the
     Warrant Shares (when issued) may be sold, assigned, transferred, pledged or
     hypothecated  or  otherwise  disposed of except:  (i) as  permitted  by any
     effective   registration  statement  under  the  Securities  Act  and  such
     registration or  qualification as may be required under the securities laws
     of any state in question,  or (ii) as  permitted by an exemption  from such
     registration and/or qualification requirements under the Securities Act and
     the  securities  laws  of any  state  or if any  such  registration  and/or
     qualification  is not  required.  For so long  as any  Warrant  Shares  are
     Registrable Securities, the Company shall cause each certificate evidencing
     any such Warrant Shares to bear the following legend:

     THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
     THE  SECURITRIES  ACT OF  1933,  AS  AMENDED  (THE  "ACT"),  OR  UNDER  ANY
     APPLICABLE  SECURITIES  LAWS OF ANY STATE,  AND MAY NOT BE  OFFERED,  SOLD,
     ASSIGNED,  TRANSFERRED,  PLEDGED,  HYPOTHECATED OR OTHERWISE DISPOSED OF IN
     THE ABSENCE OF AN EFFECTIVE  REGISTRATION  STATEMENT UNDER THE ACT AND SUCH
     REGISTRATION OR QUALIFICATION AS MAY BE NECESSARY UNDER THE SECRUITIES LAWS
     OF ANY STATE,  OR AN  EXEMPTION  FROM SUCH  REGISTRATION  OR  QUALIFICATION
     REQUIREMENTS UNDER THE ACT OR SUCH STATE LAW.

15.  Put Right.

     (a)  Exercise  of Put.  At any time or times  during  any Put  Period,  but
subject to the provisions of subsection  15(d) below,  the Holder shall have the
right to require the Company to repurchase  (the "Put") (i) all or any number of
the then Warrant Rights and/or (ii) all or any number of the Warrant Shares then
held by the Holder (collectively,  the "Put Securities"),  at an aggregate price
equal to:

     (x) the aggregate number of Put Securities  specified in the Put Notice (as
     defined below) multiplied by the Purchase Price, minus

     (y) the then Exercise Price  multiplied by the aggregate  number of Warrant
     Rights specified in the Put Notice,

     but in all events a minimum of $100,000 if the Put is fully  exercised  and
     pro-rated if partially  exercised  based on the number of Put Securities so
     exercised  (such  aggregate  dollar amount,  being the "Put Amount" and the
     $100,000  minimum  dollar amount or portion  thereof being the "Minimum Put
     Amount"),

     by delivering a written notice specifying the portion of the Warrant and/or
     the number of Warrant Shares to be purchased (the "Put Notice"). Once a Put
     Notice has been delivered, it shall remain in full force and

                                    -- 16 --

     effect and the Company  shall have the  obligation  to  consummate  the Put
     Closing  (as  defined  below)  notwithstanding  that  the  Put  Period  may
     thereafter  terminate  or be  inapplicable  because  of events  or  actions
     occurring  after  such  delivery.  The  Company  shall not be  required  to
     consummate  the Put Closing if such is  prohibited  by  Massachusetts  laws
     relating to impairment of capital upon redemptions of capital stock, but in
     such case the Company shall consummate the Put Closing immediately upon the
     termination of such prohibition and the Company's obligation to pay the Put
     Amount or Minimum Put Amount, as applicable,  upon such consummation of the
     Put Closing  immediately upon the termination of such prohibition  shall be
     an Obligation under the Loan Agreement  secured by the Collateral under the
     Security Documents.

     (b) Closing. Upon the delivery of any Put Notice, the Company shall in good
faith promptly determine the Purchase Price (including, if applicable,  the Fair
Market Value of the number of Put Securities to be purchased),  and, within five
(5)  Business  Days  after its  receipt  of the Put  Notice,  the  Company  will
purchase,  and the Holder will sell,  the Put  Securities  specified  in the Put
Notice (the "Put Closing"). At each Put Closing, the Holder shall surrender this
Warrant if being  repurchased  in whole or in part and  deliver  to the  Company
certificates  representing  any Warrant Shares to be repurchased by the Company,
in each case without any  representation or warranty (other than that Holder has
good and valid  title  thereto and the power and  authority  to  surrender  such
Warrant and/or Warrant Shares),  and the Company shall deliver to the Holder the
total Put Amount  for the  number of Put  Securities  being  repurchased  by the
Company  by  cashier's  or  certified  check  payable  to the  Holder or by wire
transfer of  immediately  available  funds to a bank account  designated  by the
Holder.  In  the  event  this  Warrant  or  the  Warrant  Shares  are  partially
repurchased at any Put Closing, the Company shall forthwith issue and deliver to
the Holder a new  certificate  evidencing,  or, as applicable,  a new Warrant of
like tenor to purchase  that number of shares with respect to which such partial
repurchase did not apply.

     (c) Survival. Notwithstanding anything to the contrary in this Warrant, the
terms of this  Section  15, if not then fully  exercised  by the  Holder,  shall
survive in full the  exercise of this  Warrant  and (i) each public  offering of
securities of the Company  (including,  without  limitation,  an IPO), (ii) each
Value Event, (iii) each Event of Default,  and/or (iv) the payment or prepayment
in full of the Obligations.

     (d) Company Option in Lieu of Put in Full. If all of the Put Securities may
then be sold by the Holder to the public in normal  brokered  transactions,  the
Company  shall have the right,  to be exercised by written  notice to the Holder
made no later than three (3) Business Days after  delivery to the Company of the
Put Notice,  to decline to consummate a Put Closing that results in payment of a
Put Amount in excess of the Minimum Put Amount and instead (i) pay to the Holder
at the Put Closing the Minimum Put Amount,  (ii) issue to the Holder,  if and as
necessary  based on the allocation of Put Securities  between Warrant Rights and
Warrant Shares,  such number of Put Securities so that the aggregate Fair Market

                                    -- 17 --

Value as of the date of the Put Notice of all Put Securities, including those so
issued, equals the Put Amount minus the Minimum Put Amount and (iii) require the
Holder to sell all Put Securities (after the exercise into Warrant Shares of Put
Securities  that are Warrant  Rights) in normal  brokered  transactions.  If the
Company so elects,  the Holder  shall sell the Put  Securities  with  reasonable
dispatch  in  normal  brokered  transactions.  On the date  that is one  hundred
fifteen (115) days after delivery of the Put Notice under the provisions of this
Section 15, the Company shall pay to the Holder the dollar amount, if a positive
figure, equal to the lesser of:

     (1)  $350,000 minus any portion of the Minimum Put Amount  previously  paid
          to the Holder under this Section; or

     (2)  the Put Price that the Company  would have been required to pay to the
          Holder for the Put  Securities  if the  Company had not so elected the
          provisions  of  this  Section  15(d)  minus  the net  proceeds  (after
          expenses  and  commissions  paid or payable by the Holder in effecting
          the  sale of the  Put  Securities  in  normal  brokered  transactions)
          received  or  receivable  by the  Holder  for  the  sale  of  the  Put
          Securities minus any portion of the Minimum Put Amount previously paid
          to the holder under this Section.

     (e) Company Option in Connection with Refinancing.

          (i)  Notwithstanding  anything  herein  that may be  construed  to the
               contrary, if at any time or times while the Loans are outstanding
               the Company  decides in good faith to fully  refinance  the Loans
               with  any  person  that is not an  Affiliate  of the  Company  (a
               "Refinancing"),  the  Company  shall  have the right to deliver a
               written notice to the Holder (the "Refinancing  Notice") no later
               than  thirty  (30)  days  prior  to  the  intended  date  of  the
               Refinancing, specifying the intended Refinancing and the intended
               closing date thereof.  The Holder shall thereupon have the right,
               by written notice  delivered to the Company no later than fifteen
               (15)  days  prior to the  intended  date of the  Refinancing,  to
               exercise the Put. If so  exercised,  the Put Closing and delivery
               to the Holder of the entire Put Amount (or the Minimum Put Amount
               if the Put is effected  under the  provisions of subsection  (d))
               shall  be  effected   simultaneously  with  the  closing  of  the
               Refinancing.

          (ii) If the Holder does not exercise the Put under this subsection (e)
               and the Refinancing  closes within three months after delivery of
               the  Refinancing  Notice,  then in  connection  with  any  future
               exercise  of the Put under  this  Section  15,  the Put Amount or
               Minimum Put Amount,  as  applicable,  shall not be an  Obligation
               under  the  Loan  Agreement  and  shall  not  be  secured  by the
               Collateral under the Security Documents.

         (iii) If the  Refinancing  does not  occur  by the  date  that is three
               months after delivery of the Refinancing  Notice, then the Holder
               shall  have the  option at any time  thereafter  and prior to the
               closing of the Refinancing to rescind its exercise of the Put and
               the Company  thereafter must wait at least sixty (60) days before
               again invoking the provisions of this subsection (e).

                                    -- 18 --

16.  Transfer. The Company will register this Warrant on its books and keep such
     books at its offices.  To effect a transfer  permitted by clause (ii) under
     Section 14 hereof,  the Holder must present  (either in person,  or by duly
     authorized  attorney) written notice substantially in the form of Exhibit B
     attached  hereto.  To prevent a transfer  in  violation  of Section 14, the
     Company may issue appropriate stop orders to its transfer agent.

17.  Replacement of Warrant.  If the Holder provides  evidence that this Warrant
     or any  certificate or  certificates  representing  the Warrant Shares have
     been lost, stolen,  destroyed or mutilated, the Company (at the request and
     expense of the Holder)  will issue a  replacement  warrant or  certificates
     evidencing such Warrant Shares, as applicable, upon reasonably satisfactory
     indemnification by the Holder (if required by the Company).

18.  Governing  Law;  Interpretation.  This  Warrant  shall be  governed  by and
     construed in  accordance  with the  internal  laws of the State of Maryland
     without  giving  effect  to its  choice  of law  provisions.  Any  judicial
     proceeding  against the  Company or the Holder  hereunder  or with  respect
     hereto  shall be  brought  exclusively  in any  federal  or state  court of
     competent  jurisdiction  located  in the  State  of  Maryland.  Each of the
     Company and the Holder (i) accepts the  non-exclusive  jurisdiction  of the
     aforesaid  courts  and  irrevocably  agrees  to be  bound  by any  judgment
     rendered  thereby,  (ii) waives personal  service of process,  (iii) agrees
     that  service  of  process  upon  it may be made as  provided  in the  Loan
     Agreement,  (iv)  waives any  objection  to  jurisdiction  and venue of any
     action  instituted  hereunder and agrees not to assert any defense based on
     lack of  jurisdiction,  venue or  convenience,  and (v)  agrees  that  this
     Warrant  was  issued  in  Maryland.   Each  party   acknowledges   that  it
     participated  in the  negotiation  and  drafting of this  Warrant and that,
     accordingly,  neither party shall move or petition a court  construing this
     Warrant to construe it more stringently  against one party than against any
     other.

19.  Information Covenants.

     (a) Notice of Stockholder Meetings. If a meeting of the stockholders of the
Company is called or if consents of the Company's  stockholders are solicited to
consider and take action on a proposal for (i) the  declaration of a dividend or
payment of a  distribution  with respect to the Class A Common  Stock,  (ii) the
voluntary  dissolution,  liquidation  or  winding up of the  Company,  (iii) the
issuance of shares of Class A Common Stock or any Common Stock Equivalents, (iv)
any Change of Control or (v) any other  action,  then the Company  send  written
notice  thereof  to each  Holder at least  five (5)  Business  Days prior to the
record date for determining  stockholders entitled to vote at such meeting or to
take action with respect to such consent.

     (b)  Cooperation.  The Company  shall  cooperate  with each Holder and each
holder of Warrant  Shares in supplying  such  information  as may be  reasonably
necessary for such Person to complete and file any  information  reporting forms
presently  or  hereafter  required  by the SEC  and/or  any  other  Governmental
Authority  as a  condition  to  the  availability  of  an  exemption  under  the
Securities Act and any applicable  state securities law for the sale or purchase
of this Warrant or any Warrant Shares.

                                    -- 19 --

     (c) Proper Books and Records.  The Company covenants that it will, and will
cause its Subsidiaries to, keep proper books and records in which full, true and
correct  entries in conformity  with generally  accepted  accounting  principles
shall be made of all dealings and  transactions  in relation to its business and
activities.

20.  Notice.  All notices and other  communications  given to or made under this
     Warrant  shall be in  writing  and  shall be  given to the  Company  at its
     address set forth in the Loan  Agreement and to Holder at its address shown
     on the books of the  Company,  or at such  other  address as such party may
     hereafter  specify  in a notice  given in the  manner  required  under this
     Section  20,  and shall be given  only by, and shall be deemed to have been
     received upon: (i) registered or certified mail, return receipt  requested,
     on the date on which such  received as  indicated  in such return  receipt,
     (ii)  delivery  by a  nationally  recognized  overnight  courier,  one  (1)
     Business  Day  after  deposit  with such  courier,  or (iii)  facsimile  or
     electronic transmission,  in each case upon telephone or further electronic
     communication from the recipient  acknowledging  receipt (whether automatic
     or manual from recipient), as applicable.

21.  Assignment; Registration of Transfer. Subject to Section 14 hereof, Warrant
     and the Warrant Shares may be assigned or  transferred by the Holder.  This
     Warrant may not be assigned by the Company.  This Warrant  shall be binding
     on and inure to the  benefit of the  parties  hereto  and their  respective
     permitted  successors  and  assigns.  Subject  to the  preceding  sentence,
     nothing in this Warrant shall be construed to give to any Person other than
     the Company, the Holder and any holders of Registrable Securities any legal
     or  equitable  right,  remedy or cause of action under this  Warrant.  This
     Warrant  may be amended or modified  only in writing  signed by the Company
     and the  Holder  and  their  permitted  successors  and  assigns.  Upon any
     assignment of this Warrant, a new warrant in substantially the form of this
     Warrant (any such new warrant, a "New Warrant"),  evidencing the portion of
     this Warrant so  transferred  shall be issued to the  transferee  and a New
     Warrant   evidencing   the  remaining   portion  of  this  Warrant  not  so
     transferred,  if any,  shall be  issued  to the  transferring  Holder.  The
     acceptance of the New Warrant by the transferee thereof shall be deemed the
     acceptance  by such  transferee of all of the rights and  obligations  of a
     Holder.

                            IRREVOCABLE SUBSCRIPTION
